Steering wheel with pivotable rim
|
en
|
A steering wheel assembly has a rim 25 pivotably mounted to a single spoke or shaft 28. The spoke may have a bore 30 at one end, a narrowed portion of the rim passing through the bore such that the rim can be pivoted about the bore, for example over the top of the shaft to rest on the dashboard (figure 4), but rotating the rim of the wheel rotates the shaft 28 and thus a hub 35 in turn rotating a steering column. A locking device 40 may be provided so that the rim can only be pivoted about the pivot point 30 when the button 40 is actuated, and/or the spoke is in a desired location e.g. vertical. The assembly may be mounted in a utility vehicle having a rotating seat (16, figure 1) and secondary controls (14, figure 1).

Methods for fabricating a stressed MOS device
|
en
|
Methods are provided for fabricating a stressed MOS device [30]. The method comprises the steps of forming a plurality of parallel MOS transistors in and on a semiconductor substrate [36]. The parallel MOS transistors having a common source [92] region, a common drain [94] region, and a common gate electrode [66]. A first trench [82] is etched into the substrate in the common source [92] region and a second trench [84] is etched into the substrate in the common drain [94] region. A stress inducing semiconductor material [90] that has a crystal lattice mismatched with the semiconductor substrate is selectively grown in the first [82] and second [84] trenches. The growth of the stress inducing material [90] creates both compressive longitudinal and tensile transverse stresses in the MOS device channel [50] that enhance the drive current of P-channel MOS transistors. The decrease in drive current of N-channel MOS transistors caused by the compressive stress component is offset by the tensile stress component.

Coin pusher using differently sized special tokens
|
en
|
A coin pusher 1000 uses coin tokens M, first special tokens AM1, and second special tokens AM2 which are larger than the first special tokens. The tokens M and special tokens AM1, AM2 are dispensed onto playfield 6 during use, and pushed into win chute 4 by pusher section 8. Special tokens falling into the win chute are captured, transported, and sorted by size. The transport means may comprise a spiral mechanism 110 which allows the tokens M to pass through but which captures and transports the special tokens AM1, AM2 via rotation of the spiral. Alternatively, the capture-transfer section may comprise a belt mechanism which allows coin tokens M to pass through but which captures and transports the special tokens AM1, AM2 (see figures 13 and 14). The sorting means may include a small entrance 124 allowing passage of special tokens AM1 but preventing passage of second tokens AM2, and a large entrance 126 allowing passage of second special tokens AM2, with the small entrance 124 being upstream of the large entrance 126. Once sorted, the first and second special tokens are stored for dispensing onto the playfield. Alternatively, one of the first or the second special tokens may be stored, with the other of the first or the second special tokens being discharged to the player as a prize. The special tokens may be spherical polyhedrons of different diameter, and may be used to initiate a bonus game.

Laminated Rack formed from Profiled Strips
|
en
|
A method of forming a rack 45 comprises providing a plurality 30 of elongate strips 10, or laminates, and securing them together, the strips being profiled to provide a profile to the rack. Preferably the profile provides a toothed rack on which a gear or roller of a stair-lift carriage may be driven e.g. of rack and pinion type. The strips may have material removed or apertures formed (16, figure 1) to reduce mass and weight. The strips may be joined using induction or interference brazing or by welding, and copper brazing may allow isotropic bending of the stack to provide a curved stair-lift rail (figure 7). Pressed features such as protuberances and hollows (20, figure 1d) may aid in securing the strips together. The strips may be staggered (figure 6) to aid in joining a plurality of stacks together end to end to form a composite rack and may be made of steel and formed in a continuous process e.g. from sheet metal on a coil. Shielding or housing 44 may be provided so that the teeth are less accessible and to hold a gear on the rack.

1308513 Tufting machine; tufted fabric SINGER CO 3 March 1970 [3 April 1969] 10068/70 Headings DIG and D1K In a tufting machine the direction of travel of the backing fabric F is reversed over the edge of a needle plate 24 so that the descending needle 22 may insert tufts at two spaced points in the fabric, first looper means 30 co-operating with the needle to form a loop 52 extending from one of the points of penetration and second looper means 38 co-operating with the needle to form a second loop 53. In one embodiment a plurality of needles 22 descent between loopers 38, through the fabric and cut out portions (28, Fig. 3 not shown) in the edge of needle plate 24, to project the loop 52 for seizing by the looper 30. After retraction of the needle the fabric is advanced and the needle bar shogged laterally before the needle descends again to penetrate the fabric at the other side of the looper 38 and form a further loop with looper 30. Between the needle penetrations a loop 53 has been formed over looper 38. The tufted fabric resulting has parallel rows of tufts 52 and 54, with diagonal loops 53 between. In a further embodiment upper loopers 58, (Fig. 6) are reciprocable in a direction parallel to the fabric feed and the needles are not shogged. Alternatively the upper loopers 38 and the needle plate 24 may be shogged, (Fig. 8 not shown).

495,254. Vehicle bodies, floors, and underframes. PRESSED STEEL CO., Ltd., and SWALLOW, W. April 9, 1937, N6. 10113. [Class 108 (i)] [Also in Group XXXI] A road vehicle comprises underframe, floor, and body structures, the underframe structure being a self-supporting unit including longitudinal side frame members of open section and of increased depth at their forward ends and the body structure also being a self-supporting unit having forward extensions arranged to mate with the forward ends of the longitudinal side frame members and in combination therewith presenting a rigid framework of closed-section members at the forward end of the vehicle. Figs. 5, 3, 4 show respectively part of the body A, the underframe, and the floor. The underframe comprises longitudinal channel-section members 11, 12 interconnected by channel-section transverse members 13, 14, 15 and a front tubular member 16, the longitudinals being shaped to correspond with the contour of the lower margins of the body and towards their rear ends 17, 18 arched upwardly to accommodate the rear axle. At their forward ends the longitudinals are of triangular shape and have apertures 19, 20, the resulting bifurcated structures presenting upper and lower flanged channel-section members. The transverse members 13, 14, 15 have horizontal flanges 23 and vertical flanges 24 by which they are secured, e.g. by spot-welding, to the webs 36 of the longitudinals, strengthening brackets 25 behind the member 14 serving primarily as the forward anchorages of the rear springs. The members constituting the underframe are preferably of sheet-metal but may be light alloy castings or of moulded material, e.g. synthetic resin. The body 41, Fig. 5, is formed with forwardly-extending portions 42 at its front end embracing the engine space, a cowl portion 43, tonneau portion 44, roof 45, centre posts 46, and threshold portions 47 and may be built up of sheet-metal stampings, or a framework of wood or metal to which exterior panelling &c. is secured, or may be composed of synthetic resin or like mouldable material. When mounting the body on the underframe, the portions 42 are arranged to bear against the bifurcated, flanged, forward portions of the underframe and to be secured thereto through the vertical flanges 32 of the latter, while in the threshold regions the vertical flanges 49 on the body sills 47 are secured to flanges 31 on the longitudinals, and in the front and rear wheelhousing regions the body panels 42, 50 are secured to flanges 32, 33 on the longitudinals which thus constitute, in combination with the body, box-section members. The floor, which comprises a pan 51 having a front footboard 52, a cut-out portion 53 for the gearbox &c., and a transmission-shaft tunnel 54 having its rear end turned upwardly to form a rear seat support 55, is secured on the underframe preferably by welding, the edges 57 of the pan 51 being secured to the horizontal flanges 37 of the longitudinals 11, 12 and to the flanges 23 of the transverse members 13, 14, 15 which thus in combination with the floor also constitute boxsection members. The floor may be secured to the body and the combined structures then secured to the underframe. The body, floor, and underframe may be corrugated or reinforced, and the underframe may include oblique open-section bracing members which may be closed on assembly of the parts. Specification 436,850 is referred to.

182,228. Marks, E. C. R., (Marswerke Akt.-Ges.). April 6, 1921. Reversing.-In an engine in which reversing is effected by means of an additional fuel-pump, working out of phase with the normal fuel-pump, the stroke of the additional pump actuates means for stopping the additional pump and re-starting the normal pump. In the form shown, the pumps I, II are actuated by rollers 3, 4 on a common rocker g. Between the roller 3 and the picton v of the normal pump I are interposed a plate 19 and a rod b slidable in a guide 20 and in a hollow toothed wheel 8 with an externally threaded hub c. Between the roller 4 and the piston w of the pump II is a piston a carrying a striker n for engagement with an inertia tappet m pivoted at o on the piston w. Reversal is effected by a spindle u adjusted by means of a handle Y and bevel-gearing 11, 13. The spindle u carries a slidable coupling-member f held by a spring 22 in engagement with the hub of a pinion 7 on the upper end of a spindle h, which is held in the normal position by a torsion spring t. A cam d on the lower end of the spindle h normally engages beneath the piston a and holds it clear of the roller 4. When the shaft u is turned into the reversing position, the pinion 7 rotates the pinion 8, the threaded hub of which causes the pinion to lift the plate 19 out of the range of the rod b so that the pump I ceases to act. The cam d is withdrawn from beneath the piston a, which is brought by a spring 14 into contact with the actuating roller 4. A cam p on the pinion 7 releases an arm 18 on the tappet m, which is moved by a spring 15 into the path of the striker n and is actuated thereby when the speed has fallen sufficiently. The resulting stroke of the piston w reverses the engine and also lifts the coupling member f by means of a disc i, allowing the spindle h and associated parts to be returned to the normal position by the spring t.

960,638. Injection moulding machines. TOS RAKOVNIK NARODNI PODNIK. March 21, 1961 [March 24, 1960], No. 10193/61. Heading B5A. In an injection moulding machine, hydraulic cylinders 3, 7 for the operation of the injection piston 4 and for closing the die parts 26, 27 respectively, are mounted on the same side of the die, the die part 26 being fixed to a plate 10 which is directly connected to piston rods 12 actuated by hydraulic cylinders 7. When fluid under pressure is supplied to spaces 20 in the cylinders 7 the die part 26 is closed against the die part 27 causing it to move against springs 11 until stopped by adjustable inserts 21. This brings the die part 27 into engagement with the nozzle 6 of the injection cylinder, and the piston 4 is then actuated to fill the die. To open the die fluid under pressure is supplied through bores in plungers 25, which are fixed inside the cylinders 7, to cylindrical spaces 24 formed inside the piston rods 12.

493,467. Type - printing telegraphy. FINCH, W. G. H. April 9, 1937, No. 10217. Convention date, April 10, 1936. [Class 40 (iii)] A telegraph transmitter suitable for use with the receiver described in Specification 437,303 or other code telegraphy system generates, on the depression of any key, a predetermined number of short impulses some of which, according to the key depressed, are modified to become long impulses. A number of permutation bars 12, are arranged beneath the key bars 10 so that on depression of a key they are either held or capable of lateral movement when urged successively by rotating cams 14 on a shaft 60 driven through a friction clutch 63, 64 by a constantly rotating motor 69. The permutation bars, when so moved, close contacts 16, 17 by means of a common bar 41. The construction of the central permutation bar is such that it is not held by any of the key bars and its associated cam has twelve equally spaced projections so shaped as to send eleven dots and one dash per revolution. The remaining cams each have one projection only corresponding to a dash and are arranged helically so that each is in a position corresponding to one of the projections on the central cam. Thus any bar which is not held by a key, when moved, converts the corresponding dot of the central bar into a dash. A detent, Fig. 4 (not shown), operated directly by the depression of any key releases the cam-shaft, and allows it to make one revolution and a mechanism operated through a lever 88 by a cam 62 holds the keyboard locked until the revolution of the cam-shaft is almost completed.

1367474 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 6 March 1972 [12 April 1971] 10270/72 Heading H3B Bubble domains are propagated in a magnetic sheet 10, Fig. 2, by current pulses in straight conductors 12-1 to 12-N. The magnetic field associated with a conductor such as 12-1 opposes the domain stabilizing field Hz on one side of the conductor and enhances it on the other; this effective variation of bias field causes a domain to move, and if alternate conductors are pulsed 180 degrees out of phase the domain will move along the sheet, following the region of least bias field. The stable domain positions are to one side or the other of the conductors as shown by numbers 1-8 on Fig. 2. Because the conductors pass to and fro across the sheet bipolar propagation pulses are used, the motion from positions 1-8 being as shown in Fig. 3; propagation in the opposite direction occurs if the currents I 1 or I 2 are reversed. In Fig. 2, a domain generator 16 has four current hoops 16L, 16S, 16R and 18. Initially 16S is pulsed to create a domain, then 16L and 16R are pulsed with loop 18 and the domain splits into two portions which move under loops 16L and 16R. The latter portion is offset by permalloy dots 20 and can be propagated by currents I 1 and I 2 . The portion under loop 16L may be returned to loop 16S and split to form another domain for propagation, the process being repeated as required. At the other end of the sheet a bubble busting loop 32 is provided. Readout is by a magnetosensitive resistor 26 connected to constant current source 28 and voltmeter 30 as described in Specifications 1,334,603 and 1,358,546. Parallel propagation paths may be used along the sheet with an appropriate number of generators, detectors and busters. The one set of propagation conductors remain sufficient however, though permalloy keeper regions are applied to them to prevent the domains drifting sideways, Figs. 4 and 5 (not shown). The keepers also raise propagation efficiency. The conductors may be arranged to give a closed recirculating path. A looped conductor may be provided adjacent the input of each path to collapse a domain when it is desired to write a binary 0.

1,185,705. Retarding action of switches. L. TROXLER. 6 March, 1967 [5 March, 1966], No. 10404/67. Heading H1N. Operation of a latching push button closes a microswitch and engages a clutch to a time drive which after a preset interval releases the latch to open the switch and disengage the clutch to allow the mechanism to return in readiness for subsequent operation without resetting. A frictionally restrained setting knob (8, Figs. 1 and 3, not shown) is rotatable between 180-degree limits to predetermine a time interval and directly moves a coaxial limiting member 22 carrying an integral abutment 25. A member 24 having an actuating nose 27 and an internal abutment 24a is carried on a loose shaft 16b and is coupled to member 22 by a spring 26 such that abutment 24a is normally held against abutment 25. Depression of the end of a lever (9, Figs. 1 to 4, not shown) urges a pin 6 axially inwards against a lever (5) which actuates a microswitch (3) and clutches shaft 16b to a drive from a geared synchronous motor (1, Fig. 3, not shown). Pin 6 is latched in this position by a shoulder 21 thereon engaging behind a spring-urged lever 19, until the drive to shaft 16b has rotated nose 27 to engage the extension 28 and thereby disengage lever 19 from shoulder 21. The pin 6 is thus released, the microswitch opens and the clutch to shaft 16b is disengaged, whereupon spring 26 returns abutment 24a to its starting position (preset by abutment 25) in readiness for another operation without resetting abutment 25 unless it is desired to change the time delay interval.

288,343. Miller, Inc., W. J., (Assignees of Miller, W. J.). Oct. 16,1925, [Convention date]. Divided on 259,965. Blowing. - A machine for forming glassware comprises a stationary base, ' supporting means movable on the base, and a. number of sets of moulds mounted in the supporting means, each set of moulds and the associated operating-devices being so arranged that they can be mounted on, or removed from, the support as assembled units. The mould table consists of a hollow hub 6, Fig. 2, which rotates about a hollow column 2 and is formed with a number of hollow arms 8, Fig. 3. The pipes for conveying compressed air to the moulds are led through the hollow arms 8, and air for cooling the moulds passes through the spaces in the arms. Each set of moulds, with their operating-gear, is carried by a structure consisting of an upper frame 9 and a lower frame 10 which are bolted together. The whole structure, with the moulds completely assembled, can be lifted on to a pair of table arms 8, and when placed in position, ports in the mould structure register with corresponding ports in the arms 8 to which the air supply pipes are connected. The halves of the parison mould are clamped to holders 36, Fig. 2, hinged on a pin 38 and opened and closed by a. sliding plate 26. The plate is operated by a fixed cam and is connected with the mould holders by a spring dog 31, Fig. 3, which yields if the mould resists movement and thus prevents damage to the machine. The pin 38 is eccentrically mounted, as shown in Fig. 2, and may be turned to adapt it for variations in the length of the hinge members. The holders 36 are hollow, and cooling air passes from the interior of the arms 8 through the holders and is blown to the mould parts and hinge members. The lower end of the mould closes around the ring mould 79 which is carried by a transfer arm 53 secured to a shaft 54. This shaft is oscillated by a rack 59 which reciprocates vertically and is operated by fixed cams. The oscillation of the shaft 54 turns the parison over and transfers it from the parison mould to the finishing mould. In order to compact a charge of metal into the parison and ring moulds, suction is applied through the ring mould and compressed air through a mould cover which is brought down on to the open end of the parison mould. The mould cover is carried by an arm 86, Fig. 3, which is reciprocated vertically, and is swung to one side when raised in order to clear the parison as it turns over. The plug 122, for forming the initial opening in the parison, is moved up and down by a rod 121, Fig. 2, operated by a fixed cam 126. After a charge is compacted, the plug 122 is lowered and air is supplied through the ring mould to blow up the charge to fill the parison mould. The rod 121 slides through a sleeve 119 which acts as a pivot for the finishing-mould holders. The halves of the finishing mould are carried by holders 141. which are hinged on the sleeve 119 and are opened and closed by a sliding yoke 150 operated by fixed cams 155. The yoke also operates parallel sliding rods 158 which open the ring mould when it is in position on the finishing mould. When the ring mould has been turned over and the finishing mould has closed around the parison, the ring mould is opened and releases the parison and is then swung back under the parison mould to receive a new charge of metal. While the new parison is being formed, a blowhead 178, Fig. 3, descends on the finishing mould and completes the blowing of the first parison, so that one parison is being blown while another is being formed. The bottom plate 163, Fig. 2, of the finishing mould is hinged to its support and is raised to the mould by a fixed cam 177. The cam allows the bottom to tilt, when the mould opens, to discharge the finished articles. Specification 156,569 is referred to. Reference has been directed by the Comptroller to Specification 164,764.

934,113. Loading silos on to vehicles. PORTASILO Ltd. March 22, 1962 [March 22, 1961], No. 10502/61. Class 78 (4). A strut 10 pivoted at 11 to a concrete silo 1 or similar container can bear on the load surface 8 of a vehicle to control tilting of the silo on to and from the vehicle. In the form illustrated the strut 10 is a U-shaped member carrying rollers 12, and its movement is controlled by a cable 14 connecting it to the legs 4 of the silo and operated by a winch 13 mounted either on the strut or on the silo. A removable brace can be connected from the legs 4 of the silo to the lower end of the strut 10 to locate it while the silo is tipped to effect initial engagement with the vehicle. This tipping may be effected by connecting a chain 17 to a line passed round a pulley (not shown) at the forward end of the load surface 8 to the winch 13. The chain 17 is subsequently connected as illustrated. After a cross brace 6 on the silo has engaged on the load surface 8 the silo pivots about the cross brace 6, still under the control of the winch 13. The winch 13 is similarly used to raise the silo from the vehicle. Jacks may be provided under the feet 5 of the silo to effect the initial tipping. The winch 13 may be replaced by a chain-puller. The keel 9 of the silo may be continued to reach the ground, and may form a skid for engagement with the load surface 8. Further lashings may be provided for preventing undesired movement of the silo. The loading and unloading operations may be assisted by movement forwards or backwards of the vehicle.

690,215. Delivering powder in measured quantities. ROSE BROS. (GAINSBOROUGH), Ltd. July 6, 1950 [April 21, 1949], No. 10588/49. Class 106 (v) [Also in Groups XVII and XXX] In apparatus for filling containers, such as bags or cartons, with measured quantities of powdery, granular, flaky or like fluent solid materials in which the powder, etc., is fed from a stationary hopper or supply line to the apertures of a rotatable apertured wheel below which the containers are conveyed in succession, the powder passes from the hopper into a collecting tunnel forming with the operative surface of the wheel a substantially enclosed space covering one or more of the apertures, the tunnel extending forwardly of the hopper and converging to a width substantially equal to that of the apertures, and a wall of the tunnel acting as a deflector for guiding the powder towards the moving apertures. As shown, powder 11 flows from a hopper 12 into a collecting tunnel 13 forming with the surface of an apertured wheel 16 a substantially enclosed space, the wheel being formed with a number of apertures 14 constituting the entrances to measuring pockets 17, 18 having pivoted bases 19 which are opened at intervals by cam mechanism to discharge the powder through shoots 22 into cartons 23 moved into position by a chain conveyer 24. The apertures are arranged in an annular channel 26, the outer wall of which is extended upwardly as a flange 25 to form the outer wall of the tunnel. The converging inner wall 15 of the tunnel acts as a deflector for guiding the powder into the channel and its forward wall 30 extends downwardly into the channel to form a scraper for levelling off the powder. The wheel 16 carries the upper portions 17 of the pockets and is carried by pillars 27 extending upwardly from a chain wheel 28 driven by worm and wheel gearing. The lower parts 18 of the pockets are carried by a wheel 33 which is formed with bosses 34 slidable on the pillars and is adjustable axially to vary the volume of the pockets by rotation of a shaft 41 which is in threaded engagement with a sleeve 38 supporting the wheel. The shaft is rotatable through worm and wheel gearing 66 driven by a shaft 64 which may be operated manually or automatically as described in Specification 686,906. The cartons are carried in pockets 58 on the conveyer which have movable bases carried by pivoted arms 61 which are raised by a stationary cam 63 as the cartons approach the filling position so that their open ends embrace the mouths of the shoots 22.

610,290. Feeding sheets to machines. CRABTREE & SONS, Ltd., R. W., and BURLS, J. A. E. April 6, 1946, No. 10672. [Class 100(i)] For feeding folded signatures to sewing- machines the folded edges of the signatures are opened out so as to permit pushing devices 9 with pushing fingers 7, 8 to engage between the centre pages of the signature. This is effected as shown in Fig. 2 by causing grippers 2 to engage the folded edge of a signature near the edges thereof, and striking devices 6 with inclined surfaces 4, 5 are moved to contact the folded edges and by movement away from the fold to cause the edges to bulge which permits the pushing fingers 7, 8 to move between the centre pages and when the motion of the fingers is reversed and the grippers 1, 2 opened, the pushers 7, 8 carry the signature to a position in which it can be engaged by a V-shaped stitching head 34, Fig. 5, which is oscillated on a guide 36 by an oscillating lever 37. As shown in Fig. 5 the signatures are fed singly from the bottom of a hopper 12 by means of oscillating,suction devices 16, which withdraw the bottom sheet past a flexible support 15 through an aperture in the bottom 13 of the hopper, and deposit the fold of the signature on a fixed gripper 2 against which moves a gripper 1 carried by a member 41 mounted yieldingly in an oscillating carrier 21. The member 41 assists separation of the signatures as it passes between the separated one and the pile. The gripping action is followed by advance of the striking devices 6 which are moved against the action of springs 33 by advance of the pushing rod 9 which finally is moved so that the pushers 7, 8 engage the opened fold of the separated signature. The rod 9 is reciprocated by a slitted lever 30 which engages a pin 29 on the rod, and the lever 30 also actuates link work which effects oscillation of the lever 17 carrying the suckers 16. The rod 9 also by means of a block 46 actuates a pivoted member 47 connected to a tappet shaft 25 which lowers the gripper member 1.

944,536. Making commutators; soldering. ROBERT BOSCH G.m.b.H. March 21, 1962 [April 28, 1961], No. 10756/62. Headings B3A and B3R. [Also in Division H2] A method of making a commutator having U-shaped connecting lugs at one end of its segments comprises lifting a portion of the segments by paring, fitting the web of the U-shaped connecting lug within the resultant recess, and fixing it therein by means of said pared portion. In order to facilitate the paring operation two grooves 16, 17, Fig. 3, may be cut in each segment; these grooves may also be used to assist in the location of the connecting lugs, which in this case have projections extending downwards of the web from the lugs (Figs. 5 and 6, not shown). The connecting lug may also be soldered to the commutator segment during a dip soldering operation which is carried out to join the armature windings to the connecting lugs, or the lugs may be soldered to the commutator segments prior to assembling the armature. Bridging of the commutator segments during the dip soldering is prevented by forming the insulating layers separating the segments such that they project slightly above the outer diameter of the segments. The invention is particularly suited to the assembly of commutators for machines utilizing high currents, such as I.C. engine starter motors.

Improved suspension means for the superstructures of motor vehicles

498,978. Vehicle suspensions. KOLBE, J. April 8, 1938, No. 10770. Convention date, Aug. 12, 1937. [Class 108 (ii)] In a suspension for a motor-vehicle superstructure of the kind in which the supporting elements on the axle comprise inclined links or guide members adapted automatically to tilt the body inwardly on a curve, the links or guiding elements of the front and rear axles are positively coupled so that their movements take place in the same direction. In the arrangement shown in Fig. 1, the superstructure 1 is supported on the front and rear axles 4, 7 respectively by means of inclined pairs of links 2, 3 and 5, 6, which are associated with a common longitudinal rotary tube 8 through the medium of levers 9, 10 and links 11, 12. In a modification, Fig. 5, the links 2, 5 are provided with arms 22, 23 which co-operate with pistons 24, 25 in the cylinders 20, 21 of an enclosed fluid system, while in a further construction the links 2, 5 are inter-connected by wires passing around pulleys and attached to bellcrank levers. With such constructions the movements of the links are necessarily also equal, so that the axles remain parallel. If, however, the vehicle is intended for less smooth roads, an initially stressed spring or equivalent device may be interposed between the links 2, 5 and the common mechanical or fluid connection, such device tending to constrain the axles to move in the same direction, but yielding to permit a certain differential movement. Thus, as shown in Fig. 9, between the link 11 and the common connecting tube 50 are arranged a pair of pivotally connected bifurcated elements 40, 41 and a stressed spring 43, which tends to constrain the elements 40, 41 to move as a rigid unit but which yields on excessive stress resulting, for example, from the axles assuming a non-parallel position on a rough road. In other modifications the yielding elements may consist of torsion tubes or of springs associated with a fluid system.

659,650. Molding hollow rubber balls. SWIFT TENNIS BALL CO. PROPRIETARY, Ltd. April 26, 1949, No. 11080. Convention date, May 4, 1948. [Class 87 (ii)] A method of moulding a hollow rubber ball from natural indiarubber, synthetic rubber, or rubber substitute material, comprises shaping integrally with one another a major ball part 11, Fig. 3, and a minor ball part, the part 11 being formed as a hollow spherical segment and the minor part being formed as a plurality of petals 13, 14, 15, 16, integrally connected to the segment around the opening thereof and arranged so that they may be united to close the opening of the part 11 to form a hollow spherical rubber ball. The petals have bases which lie in a common plane where the converging edges 17, 18 of adjacent petals meet. Between the edges of adjacent petals are V-shaped notches or slits 22 which are prevented from extending by a bead 24 formed upon the outside of the ball, which bead reinforces the petals and forms a fold line for them. Apparatus for moulding the major and minor parts, comprises a core, Figs. 5, 10, and mould halves 41, 42. The core has a stem 32 upon which is formed a pearshaped extension composed of a truly spherical solid portion 33 combined with a frusto-conical portion 34. An annular bead 33a is formed around the lower boundary of the part 34, which part 33a produces the bead 24 on the ball part 11. Four tenons, 35, 36, 37 and 38, having outer convex surfaces, Fig. 10, are formed on the part 34, and the petals are moulded in the V-shaped recesses formed between the tenons. In operating the method a quantity of mouldable rubber material 40a is placed in the lower mould half 42, Fig. 5, prior to closing the mould on the core, and heat is then applied to the core by means of steam or electrical elements. After this stage the mould is broken, and the core removed by expanding the formed hollow rubber shell 11, Fig. 10. The shell is then placed in a single or multiple curing mould, the petals are pressed down to complete the spherical shape, and the mould is subjected to heat to complete the curing. Internal pressure may be applied either by a gas generated from pills introduced before sealing the ball or by compressed air. The petal edges 17, 18, come together as a butt joint when they are pressed down, but a mitred or overlapping joint may be used instead. The joints so formed are sealed with a suitable cement before the ball is cured. In the curing operation the annular bead 24 is obliterated. In the Provisional Specification the V-shaped slits between the petals are prevented from extending by small nipples formed on the inner surface of the ball at the extremity of each slit, or each slit may be terminated by a circular aperture afterwards filled with cement.

530,568. Cathode-ray tubes. ARDENNE, M. VON. April 12, 1939, No. 11134. Convention date, April 13, 1938. [Class 39 (i)] [Also in Group XX] In an ultra-violet microscope the whole path of the U.V. rays-except in the immediate neighbourhood of the object-is through spaces substantially free from atmospheric air; the space may contain hydrogen. The rays-of less than 2000 A.U.-are formed in a discharge tube A with a filling of xenon or krypton in combination with argon and neon, and a fluorspar window B; they pass through a Christiansen filter C- consisting of fluorspar narticles in a liquid having the same refractive index as the fluorspar-to a lens E, which closes an orifice in an exhausted chamber F and through a second lens I on to the object K. The position of the object is adjustable for focusing purposes; the object is in an immersion liquid such as hexane which does not absorb the desired wave length and with the fluorspar filter and lens passes substantially monochromatic light. The object support is of fluorspar. The rays then enter a second evacuated space H through the lens M on to an eye piece N, which for focusing directs the image on to the photo cathode P of an image transformer; the emission therefrom is focused and accelerated on to a screen S by electrodes T, R, a window V permitting observation of the screen S. The electron optical arrangement is used only to focus the object, the electron apparatus being slidable with a photographic plate holder O; the plates, which take up the position of the photo-cathode, must be sensitive to U.V. rays. Alternatively the photographic plate may take up the position of the screen S when ordinary plates can be used; or the cathode may act also as a mirror to reflect part of the U.V. rays on to a photographic plate while the other part is used to energize the screen S the electrons being deflected electromagnetically. The envelope containing the electron device and the photographic plates is connected to the space F by a channel G. The photo cathode may be translucent in which case the image produced thereon mav be directly observed and photographed. The cathode may be a layer of platinum or aluminium deposited by evaporation.

513,542. Hydraulic machines. ALDOUS & CAMPBELL, Ltd., and HALLIDAY, J. W. April 12, 1938, No. 11214. [Class 69 (ii)] [Also in Group XXX] Hydraulic apparatus is brought to rest gradually and exactly at a selected point, for example a hydraulic lift is stopped at a selected floor, by mechanism operated automatically by the cage or moving body as it approaches the stopping place to cause restricted delivery of the operating fluid to, or exit from, the ram cylinder. In the illustrated form showing the application to a hydraulic lift, the main delivery and exhaust valves are cut out on approaching a floor at which it is desired to stop, and a small auxiliary valve automatically brought into operation. Fig. 1 shows in plan a main control valve having a port 4 leading to the ram (not shown) and communicating alternatively with an inlet port 2 from the pressure main and an exhaust port 3. Depression of an appropriate button on the cage or at a floor energises the motor 14 and the solenoid 23. The motor drives worm gear 15 and epicyclic gear 13, while the solenoid applies brake blocks to fix the outer ring of the gear so that the drive becomes effective to move the crank 6 through 90 degrees in one direction or the other until stopped by a limit switch 17, and thus through the connecting rod 5 slides the valve into one or other of its extreme positions, in which the ram is connected to the main or to exhaust. The pressing of a floor-selector switch causes ramps in the well to operate a switch as the car approaches the selected landing and so close the main valve and open one of the auxiliary valves to enable the cage to creep up or down to the landing. The circuit thus established energises one or other of the solenoids 29, 30, Fig. 5, and raises the armature 43 to tilt the bar 40 about the remote pivot 39. This opens one of the needle valves 35 and also compresses the restoring spring 50. At exact floor level another ramp in the wall opens the circuit and all valves are closed. Should the cage creep away from the landing one or other of the needle valves are opened automatically, and restoration takes place. The two needle valves are connected by pipes 55, 57, Fig. 1, to the corresponding pipes of the main valve. Should the current fail, the main valve can be controlled immediately from a hand rope on the wheel 11 which is connected to the crank 6 by chain gear 8, 9. This latter drive is isolated from the motor 14 by reason of the de-energising of solenoid 23 rendering the epicyclic gearing 13 non-effective.

681,811. Vaporizers. WILLIAMS, K. April 28. 1949 [May 17, 1948], No. 11365/49. Class (iii). In a method of producing fuel for an internalcombustion engine having a carburetter 10 and a heat-exchanger 3 comprising admixing water in a firely divided state, with the working substance to be induced in the engine between the carburetter and heat-exchanger and raising the temperature of the water and working substances gradually over a range from the existing atmospheric tempeature to approximately 170‹ to 180‹ F. whereby the water in the mixture is vaporised at tempeatures below its boiling point, at least part of the heat required for the vaporization of the water is supplied by the latent heat of condensation of water vapour in the exhaust gases; the water may be introduced in sufficient quantity to substantially saturate the mixture at the upper limit of temperature. The fuel-air mixture from the carburetter 10 has water added to it from another carburetter 7 and an atomizing jet 5, the water being cut off at starting until normal operating temperature is reached. The air-fuel-water mixture tnen traverses a reverse flow heat-exchanger 3 before entering the inlet manifold 19. The heat exchanger 3 which comprises a number of curved, fine-bore tubes 14 is connected to the exhaust, and the condensate either escapes with exhaust gases or is passed from a water trap in the exhaust outlet 17 to an economizer, not shown. The engine water jacket and radiator may be materially reduced in size or dispensed with. In a modification the water is atomized and injected directly into the fuel-air mixture in the heat-exchanger by a nozzle supplied from an engine driven pump whilst in compression-ignition engines, air only is passed over the water atomizing means. The heat-exchanger, cylinders, cylinder heads and inlet and exhaust manifolds are lagged. The Provisional Specification describes also a heat exchanger with one through conduit instead of a number of fine-bore tubes; the exhaust pipe passes through the conduit, and the spaces between and within the conduit and pipe are filled with such material as copper wool. The condensate from the exhaust may be removed to the container from which the water nozzles are fed.

Pigmented cellulose esters and ethers suitable for enamels, fillers, primers, &c., are obtained by causing a suspension of pigment in a suitable liquid to penetrate, under pressure, a more or less compressed mass of the ester &c. For example, a quantity of the ester or ether wet with water is charged into a centrifuge and, after removing the bulk of the water, the centrifuge is slowed down and an aqueous slurry of pigment is run in by gravity or pressure feed; when all the pigment has been added, the speed is increased until the bulk of the liquid is removed. To bring the mass into condition for working up into an enamel &c., it is treated with mixtures of industrial spirit and water containing progressively increasing quantities of spirit, followed, if desired, by treatment with isopropyl alcohol, toluol, xylol or other non-solvent for the ester &c. The contents of the centrifuge are removed and stored or dispersed in a suitable solvent mixture with suitable gums, softeners, plasticizers, inhibitors, &c. An hydraulic press may be used instead of a centrifuge. In an example, water wet nitrocellulose is pigmented with an aqueous suspension of Prussian blue, the water being subsequently displaced by industrial spirit. Cellulose esters and ethers include the nitrate and acetate, and methyl, ethyl and benzyl cellulose. Pigments include blanc fixe, chrome yellow and green, Prussian blue, lakes, lithopone, iron oxide with or without dyestuffs or precipitated organic or inorganic dyestuffs. The ratio of pigment to ester or ether may range from 4-300 parts of dry pigment to every 10 parts of dry ester &c.ALSO:Pigmented cellulose esters and ethers suitable for enamels, fillers, primers, &c., are obtained by causing a suspension of pigment in a suitable liquid to penetrate, under pressure, a more or less compressed mass of the ester &c.

1,140,874. Grinding. NORTON CO. 16 March, 1966 [19 March, 1965], No. 11596/66. Heading B3D. Apparatus for cutting thin hard material comprises multiple blades 123 separated by spacers 124 extending substantially over the whole length and width of the blades and clamped therewith in backing plates 42 carried by a blade support frame 31 which is reciprocated along slideways 23, 24 on a main support frame 14, and a workpiece feed mechanism 81 mounted on a bracket 71. The workpiece may be a thin wafer of semi-conductor material having a plurality of microminiature electronic circuits which is to be cut into a plurality of small dice of, for example, 0À030 x 0À030 inch, each bearing a complete circuit, the wafer being 0À010 inch thick. Support-structure 14 is mounted on three pads 16 on a support 12 having three feet 17. A blade-supporting frame 31 is connected by a quick-release device 61 to a plate 56 having a slot 57 engaged by an eccentrically driven pin 55 whereby the frame is reciprocated along the slideways. One end of the backing plates 42 is located by pins 131 on the frame, and the other end of the frames has means for aligning the blades with the movement of the frame. The edges of the blades may be ground so as to be in a common plane, and when worn may be adjusted by shims. The bracket 71 is secured to the support structure 14 by bolts 77 and has a nylon bearing 91 slidably supporting a cylindrical plunger 94 of the feed mechanism which is prevented from rotation by rollers 104 engaging a bar 101 fixed to an upper flange 95 supporting a workpiece supporting plate 96. The plunger is urged upwardly by weights 115 on a lever 110, which is pivotally mounted on the support 12 and is formed with a yoke having rollers 117 engaging the flange 95 and can be lowered by movement of a pivoted lever 192 engaging a roller 191 on the plunger. The plate 96 supports a series of vacuum assemblies 141 for holding the workpieces, each assembly being disposed between a pair of supports 151 having clamp member 153. To locate and orientate the workpieces, a thin transparent flat member (161, Fig. 7) is mounted on the supports and the blades are reciprocated over the member in the presence of abrasive to scribe reference lines thereon. The member is then replaced by two short blocks (162, Fig. 8) and reference lines are scribed thereon by the blades. The workpieces are then bonded to circular workpiece supports (175) and held by a light vacuum on the assemblies (141), and the thin transparent member (162), with spacing blocks (163) secured thereto, is inverted end for end and aligned, by means of a viewing device and the reference lines with the short blocks (162). The workpiece is then accurately positioned beneath the reference lines and held in position by a high vacuum. The procedure is repeated for each assembly and the transparent member removed so that the blades can be reciprocated to cut the workpiece. The procedure is then repeated with the workpiece displaced through a right-angle to produce the dice.

1302595 Washing textiles RIMAR SpA 11 March 1970 [26 March 1969] 11671/70 Heading D1L Textile fabrics are washed with a solvent (which may be an organic solvent, water or detergent solution) in an apparatus comprising a perforated chamber or basket 1 which is swingable about an axis Z and through which the fabric 19 passes in folded form, this chamber being within a stationary tank 12 containing the solvent 2. The chamber 1 is, as shown, of semicircular shape the passage being broader at the outlet end B for the fabric than at the inlet end A. Blades 17 are arranged protruding from the perforated sides 15 and 16 of the chamber, alternately on one side and the other similar blades 4 being arranged on the surfaces 13 and 14 of the stationary tank 12 interleaving with those on the chamber 1, such that when the chamber is swung back and forth by means of bar 18 and crank 5 and 5', alternate pressure increases and decreases on either side of the chamber where the blades approach one another or move apart cause a pumping action of the solvent across the chamber through the perforations. The increasing width of the chamber from A to B also causes the fabric to move through the chamber from A to B as the chamber swings. The solvent 2 is circulated by pumps 28 and 29, these drawing solvent from the tank and passing it to sprays 30 and 34, to the latter spray via a distillator (not shown). The fabric is drawn off via hollow rolls 22 and 23 both of which are subject to a suction draught of air, this drying the fabric.

1430499 Retractor reel SIGMATEX AG 15 March 1974 [16 March 1973 1 Oct 1973] 11688/74 Heading A3V A reel locatable by a pawl 74 engageable with ratchet 32 includes a flywheel 42 rotatable on the reel shaft and a locking member couplable between the shaft and flywheel so that on relative rotation there between at a predetermined acceleration of shaft, locking of the pawl is initiated. The reel is mounted on a shaft 22 having an enlarged end 34 which entrains the flywheel 42 by means of a peg 46 and coil, spring 50 housed in a slot 38. A locking dog 54 is lodged in mutually opposite recesses 40, 52 in the end 34 and flywheel. An annular actuator 56 having an internal ratchet 60 surrounds the end -34 and is urged against a stop by a spring 66. When the belt is un-reeled rapidly, relative rotation between the end 34 and flywheel 40 forces the dog radially outwards to entrain the ratchet 60. Rotation of the actuator takes arm 64 anti-clockwise so that it strikes pawl 74, forcing it into the path of the teeth of a ratchet 32 fixed to the reel shaft. The reel is thereby arrested. In a modification the dog and coil spring are replaced by a leaf spring (110 Fig. 7 not shown) flexed to project beyond the flywheel periphery on relative rotation of the flywheel and shaft to initiate locking. The reel will also lock if pendulum 86 is displaced thereby raising lever 96 against the pawl.

Switches, quick-action.-A quick make and quick break action mounted in brackets A independently of the switch mechanism and connected on one side, with lost motion, to the operating handle and on the other to the switch spindle comprises a double cam F loose on a short spindle C mounted in the bracket and driven by the operating handle so as to react with a roller G on a spring-held bar H to give a snap-action. The cam member has a crosspiece J<1> engaged by the fork of the usual loose switch handle and engaging at its central portion with a gapped intermediate sector E fixed on the short spindle C. In opening the switch, the contacts remain in the closed position bv friction while the cam member reaches the deadcentre position in relation to the spring roller, whereupon the projection J<1> strikes the sector and drives the switch to the open position where it is retained by the spring-controlled detent L pivoted on the bar H. In closing the switch, the depression of the bar releases the detent when the dead-centre position is reached and a snap-action results as before.

[Also in Division C1] Carbons produced by carbonization of pitches having a highly aromatic hydrocarbon content are hardened and their graphitizibility reduced by adding from 10 to 16% by weight of ammonium sulphate as a solid or in solution to the pitch before its carbonization. Suitable pitches are those obtained from the distillation of high temperature coal tars or cracking bitumens. In one example the mixture is carbonized at a speed of 1‹ C. per minute in a neutral atmosphere up to 550‹ C. and is then carbonized at a heating speed of 3‹ C. per minute up to 1000‹ C. and is maintained at that temperature for half an hour. The hard carbon product has high electrical resistivity and may be used as a reducing agent in electro-metallurgy, as a furnace heating element, as resistance granules in graphitization furnaces, and as raw material to prepare active carbon.

331,948. Houdaille, M. A. M., and Etablissements M. Houdaille. April 19, 1929. Fluid friction vibrationdampers of the rotary or oscillating type are provided with a thermostat utilizing the volumetric expansion of a fluid or semi-fluid to control the flow of the damping-fluid, the thermostat being of the cylinder - and - piston type and arranged along the axis of the rotating elements. When the viscosity of the damping-fluid varies in accordance with changes of temperature, the effective size of the leak orifice is correspondingly varied by the thermostat control so as to ensure a constant damping effect. The apparatus shown in Figs. 2 and 3, is of the type disclosed in Specification 299,798 and includes a movable vane secured to the shaft 15 and oscillating in a circular casing within limits determined by a semi-circular abutment 16. The chambers 13 on opposite sides of the vane are connected by passages 17, the flow through these passages being controlled by a leakage orifice in the end of a piston rod 18, the other end of which is provided with a piston 10 working in a cylinder filled with fluid, for example vaseline. A spring forces the piston 10 into its cylinder. In the modification shown in Fig. 1 the end of the thermostat piston-rod 19 bears against a ball 4 which rests in a conical recess in the end of an expansible valve 3 by which the flow of damping-fluid is controlled. When the temperature rises the piston-rod 19 is forced towards the left and the walls of the valve 3 are expanded so as to reduce the area of the leakage space between the outside of the valve and the passage in which it is placed.

199,555. Holt, H. E. S. May 2, 1922. Transferring articles to conveyances in motion. -In transferring mailbags or like articles from the ground to aircraft in flight a coupling-member such as a tapered weight o is attached to the end of a hoisting-rope n, lowered from the aircraft and, by means of a guide structure d, is guided into engagement with a coupling - member b attached to the load. In the construction shown in Fig. 1 the structure d is in the form of a conical tube with a wide entrance and a slot along its upper edge, and guides the weight o into gripping engagement with the tapering tube or coupling-member b attached by a cord c to the mail-bags j, j<1>, j<2>. In order to relieve the aircraft from excessive shock due to the inertia of the load, the latter may be divided into several portions j, j<1>, j<2> which are successively lifted, or the supporting platform a may be arranged to release the load with an initial velocity. As shown, the platform a is mounted on a pivoted bar g connected to a spring h but normally held by a catch i so that, when the latter is released by the movement of the coupling-member b, the platform and load are actuated by the spring h. A single cord c provided with a seal may be arranged to close a number of mail-bags by passing it through holes in a socket m, Fig. 4, at one end of a securing-band k and through holes l at the other end of the band. The platform a and guide structure d are mounted on a pillar f revoluble on a base e so as to be adjusted according to the direction of the wind. The rope n, Fig. 2, is prevented from trailing at too great an inclination to the vertical by an inclined vane p connected to a parachute r. This Figure also shows a modified form of guide-structure consisting of a base d<2> mounted on wheels d<4>, converging sides d<1> and a pivoted end plate d<3>.

248,594. White, A. E., (Wellman-Seaver- Morgan Co.). May 12, 1925. Valves controlled by pilot or relay valves ; casings.-A valve of the kind in which the main valve member slides in an inner casing arranged axially in the pipe line has the nose of the valve member and the rear part of the inner casing formed with a convex longitudinal curvature. The valve is actuated by pressure derived from the centre of the conduit through a pipe 20 acting on a piston 15 arranged to work in a cylinder 17 mounted in the inner casing. The inner casing is attached to the outer casing by webs 12 which are extended to form guides for the valve member and the lower one is widened with a stream line contour and is formed internally with two passages 23, 24 leading to the space 17<a> behind the piston and the interior of the valve member respectively. A pressure equalizing pipe 18 fitted with a stop valve 18<a> connects the passage 24 with the main conduit beyond the valve seat, one or both ends of the pipe being below the axis of the valve. Fluid pressure under the control of an auxiliary valve is admitted to or exhausted from the chamber 17<a> through the passage 23 and a pipe 21 secured to the cover 25 while a pipe 22 arranged within the passage 24 serves the chamber 17<b> on the other side of the piston. Pressure is admitted to the chamber 17b through a port 27 in the side of the cylinder adapted to be obturated by the piston and through a port 27a in the end of the cylinder fed through a pipe 26 provided with a non-return valve 29. Pressure is exhausted through the port 27 alone so that the closing movement is cushioned by fluid trapped in the cylinder. The indicator rod 34 is connected to the control valve lever 36 and is moved by a stanchion 30 secured to the valve member just behind the valve face. This stanchion is guided and protected by depending walls 3 formed on a cover 32 detachably secured to the casing. In a modification the stanchion is guided by a keyway on the cover and is protected by a single wall on the cover co-operating with one of the ribs 12. Specifications 182,156 and 182,414 are referred to.

956,478. Tent frames. I. R. POLLARD. April 5, 1962 [April 10, 1961; April 28, 1961; Sept. 14, 1961; Oct. 20, 1961], Nos. 12830/61, 15475/61, 33045/61 and 37781/61. Heading E1A. [Also in Division B7] Relates to a tent framework incorporating a vehicle luggage rack (see Division B7). The vehicle roof luggage rack 20, Figs. 1 and 2 comprises longitudinal tubular frame members 21, 22, 27 and 28, and transverse tubular frame members 23, 24, 25 and 26, tubular diagonal members 32 to 35, and tubular central transverse members 36, 37, the members 32 to 37 being connected to a central boss 29 and having slidable extensions 32<SP>1</SP> to 37<SP>1</SP>, the latter being securable to leg members 47 or 56, whereby the rack and legs form the tent supporting framework. The extensions are urged to their outer positions by springs and are lockable in those positions or in their retracted positions by spring-urged locking pins 38. The legs for each corner of the rack are as shown in Fig. 4, and have telescopic lower and upper parts 49, 50<SP>1</SP> securable by grub screws 51. The portion 50 has tubular sockets 52, 53 disposed at right angles to each other and a central socket 48 for connecting to an extension e.g. 34<SP>1</SP>. The sockets 52, 53 are connected to adjacent leg sockets by brace members 69 of the form described with reference to Fig. 10 (not shown). The leg members 56 are as shown in Fig. 7 and sockets 57, 58 for connection to brace members 69 are aligned with one another and normal to the central socket 59 for connection to the extension 36<SP>1</SP> or 37<SP>1</SP>. Cords, e.g. 55, extend from the upper end of one leg to the lower end of an adjacent leg and serve to brace the tent framework. The boss 29 is provided with a tubular pillar 30 housing a spring-urged peg 31 which is adapted to pass through a hole in the tent fabric. The legs 47, 56 are connectible to the extensions 32<SP>1</SP> to 37<SP>1</SP> whilst the rack 20 is on the vehicle. Thereafter the rack feet 40, in the form of suction pads, are released from the vehicle roof and the vehicle driven from under the framework. In another embodiment the outer ends of the diagonal extension members are connected together by telescopic struts. In a further embodiment the roof rack is formed of two longitudinally telescoping parts as described with reference to Fig. 16 (not shown). According to yet another embodiment, the rack may have solid side and end walls rotatable outwardly of the rack about horizontal axes to horizontal positions in which they may be locked, the cords then serving for the same purpose as the extensions 32<SP>1</SP> to 37<SP>1</SP> The framework of the embodiment of Fig. 1 is covered with fabric to form a tent as described with reference to Figs. 12 to 15 (not shown).

663,419. Grinding lenses &c. ABBEY, A. (American Optical Co.). May 13, 1949, No. 12862/49. Class 60 A surfacing-machine has a work-supporting member and a tool-supporting member, the latter being adjustable about an axis substantially perpendicular to the axis of a rotating cup tool and intersecting the effective abrading portion of the latter, means for yieldably feeding one of the supporting members in an arcuate path about a second axis parallel to the first-mentioned axis, and means for displacing the second axis to vary the curvature produced on the work. The machine base 15 supports a bed 16, Fig. 1, on which is slidably mounted a supporting plate 19 rotatably carrying a post 32, Fig, 3, in roller bearings 36 and 45. This post is keyed to a turntable 33 fixedly secured to a table 77 on which is slidably mounted a carriage 85 connected by a pivot 95 with a quadrant plate 94 carrying, by means of a transverse slide 120 and a longitudinal slide 130, an electric motor 137 for driving a cup-type abrasive tool 140 with a curved edge 141. The lens blank 183, Fig. 9, is stuck by pitch to a block 184 secured to an adaptor 186 which forms a tapered fit on a plug 173, Fig. 6, secured to the end of a spindle 153 and provided with a nut 175 for the purpose of dislodging the adaptor. The spindle contains a spring 181 bearing against one end of a displaceable rod 178 which may be secured with respect to the spindle by a screw 182 and abuts the screwed member 162 of a micrometer adjustment 157 supported on a head 143 attached to the bed 16. The spindle rests in a V-grooved chuck 145, which is preferably magnetic, and may be displaced longitudinally with respect to the chuck by turning the adjustment 157 which thereby controls the depth of feed. During the cut, the tool is swung through an arc about the post 32 by the descent of a weight (not shown) which is attached to the turntable 33 by a cord 49, the turntable being locked or released by a cam device 72 and the rate of rotation being adjustably governed by a valve-controlled dashpot the piston of which is engaged with the post 32 by a rack 59 and a gear 60. The radius of this arc corresponds to the curvature to be imparted to the blank in the horizontal meridian and is determined by the adjustment of the carriage 85 which is effected by a screw 76 provided with a handle 81, the extent of the adjustment being indicated by two scales 92, 93 calibrated in diopters and millimetres. The curvature of the lens in the vertical meridian is determined by the tilt of the tool about the pivot 95 and the quadrant plate 94 co-operates with an arcuate scale on the carriage 85 to show the extent of this adjustment. A clamp 113 holds the plate 94 in the position to which it has been approximately adjusted and, after the clamp has been tightened a fine-screw adjustment between the clamp and the plate is used to obtain the precise setting. Wear of the tool is allowed for and its correct positioning in relation to the axis of the pivot 95 is ensured by inserting a gauge 195 in a bore in the pivot and adjusting the slide 130 by means of a screw 132 until the rod makes contact with the face of the gauge, and then adjusting the slide 120 by means of a screw 122 until the centre of the curved edge is aligned with the edge of the gauge 195 when the latter has been rotated through a right angle about the pivot axis from the illustrated position. The gauge is provided with one or more locating pins to fit holes in the pivot which is covered by a cap 101 when the gauge is not in use. A jig 188 provided with two V-grooved members 189 and an axiallyadjustable pin 192 is used to adjust the rod 178 so that the distance from the end of the rod to the face of the lens blank exactly corresponds to the distance between the tip of the screwed member 162 and the abrading surface of the tool. To enable a zero setting of the micrometer to be made and to allow for wear of contacting parts, a bush 161 in engagement with the member 162 is adapted to be axially displaced with respect to the head 143 and locked in adjusted position. Since the work, and hence the position of the rod, is more or less fixed in relation to the bed 16, the adjustment of the carriage 85 has to be compensated by an equal and opposite adjustment of the supporting plate 19 which is similarly provided with scales 30, 31, the adjustment being affected by a screw 26 connected by gears with a handle 21. During operation the tool is enclosed in a casing provided with splash guards and a hinged cover and is fed with coolant or lubricant from a tank in the base 15 by means of a pump, the fluid being returned to the tank by gravity. A vacuum system may be used to draw the mist formed by the fluid upon engaging the tool from the casing and expel it into the tank.

130,776. Robinson, J. T. Aug. 8, 1918. Benches, work.-A fabric-covered ironing board 5 is hinged at one end 6 to an open frame 1 having inwardly folding hinged legs or supports 2 held in the. setup position by removable strips 4 engaging staples 3 in the supports and frame and projecting above the frame at one end on either side of the narrow end of the board 5. Below the frame is arranged a loose fabric sheet 11 to prevent the work from dropping on the floor. The sheet is mounted on rods 10 supported in hooks 9 depending from the frame, one of the rods being fitted with a crank handle 12 to serve as a roller. A staple 13 on this rod may be engaged over the corresponding hook 9 when the fabric is in position, to prevent accidental unwinding.

1-Phenyl-2 : 3-dimethyl-4-methyleneamino-5-pyrazolone is manufactured by treating an aqueous solution of 1-phenyl-2 : 3-dimethyl-4-amino-5-pyrazolone with formic acid. The product may be isolated as an oily monomer or preferably as a solid polymer which is formed on heating, or prolonged standing in the cold or on stirring with water and a water-immiscible solvent, e.g. benzene or toluene. In examples: (1) the reaction is effected in neutral aqueous solution in the cold, with or without stirring, and the oily monomer is separated; (2) alkali e.g. sodium carbonate, caustic soda or caustic potash, is added to the solution in which the reaction is effected, and the oil formed is taken up in benzene, the benzene solution is decanted and rapidly evaporated, and the residue isolated in the form of a salt, e.g. hydrochloride or sulphate; (3) in the process of (1), a large amount of benzene is added before or after the addition of the formaldehyde, the whole is stirred, the benzene evaporated and the polymer separated in powder form; if a smaller amount of benzene is used, a granular powder is obtained directly without evaporation of the solvent; (4) the process is effected with heating in the presence of a moderate amount of benzene, which is then evaporated, causing the polymer to separate in powder form; (5) the process of (4) is carried out in the cold with rapid stirring; (6) a solution of 1-phenyl-2 : 3-dimethyl-4-amino-5-pyrazolone hydrochloride and hydrochloric acid (obtained by hydrolysis of 1-phenyl-2 : 3-dimethyl-4-sulphamino-5-pyrazolone) is neutralized with sodium carbonate and treated as in (3) (using a large amount of benzene); (7) the solution neutralized as in (6) is made alkaline with caustic soda or other alkali and further treated as in (2), with the alternative of boiling the benzene or stirring it with water to obtain the polymine product; (8) the process of (6) is carried out with a smaller amount of benzene to produce the polymer in granular form. 1 - Phenyl - 2 : 3 - dimethyl - 4 - dimethylamino - 5 - pyrrazolone is manufactured by simultaneous or successive reduction and methylation of monomeric or polymeric 1-phenyl-2 : 3-dimethyl-4-methyleneamino-5-pyrazolone. The single stage process may be effected by means of formaldehyde and a reducing agent, e.g. metal and an acid, formic acid or hydrogen in the presence of a hydrogenation catalyst, such as platinum, palladium or nickel. For the two stage process, reduction may be effected, for example, with acid and a reducing metal, e.g. hydrochloric acid and zinc, with formic acid under heat, or with hydrogen in the presence of a metal hydrogenation catalyst, and the resulting 1-phenyl-2 : 3-dimethyl-4-monomethylamino-5-pyrazolone may be methylated with a methyl halide, dimethyl sulphate, or formaldehyde in the presence of a reducing agent. In examples, simultaneous reduction and methylation are effected by means of formaldehyde under the following conditions: (9) in alcoholic solution in the presence of hydrogen and active nickel, by stirring at ordinary temperature and pressure or with the use of elevated temperature and superatmospheric pressure; (10) in the presence of zinc (or other metal, e.g. aluminium) and dilute hydrochloric acid (or other acid, e.g. sulphuric); (11) in the presence of aqueous formic acid at 85-95 DEG C. A sample has been furnished under Sect. 2 (5) of 1-phenyl-2 : 3-dimethyl-4-dimethylamino-5-pyrazolone prepared by reducing the methyleneamino compound with aqueous formic acid and treating the resulting solution of 1-phenyl-2 : 3-dimethyl-4-methylamino-5-pyrazolone formate with formaldehyde and formic acid.
