369,596. Discharge lamps. LEDERER, A., Hermesvilla, Vienna. Dec. 12, 1930, No. 37595. Convention date, Dec. 28, 1929. [Class 39 (i).] The getter substance which is introduced into an electric glow discharge lamp for the purpose of removing gaseous impurities is disposed in such a position that when vaporized it will deposit on a portion of the envelope, such as the neck, through which substantially no light is required to be transmitted. In the form shown the bulb 1 is provided with a neck 5 through which the stem carrying electrode supports 4 extends, and a member 7 projecting downwardly from an electrode support carries a ring 6 which serves as a carrier for the getter material. To enable another gas such as mercury vapour to be used in the lamp in addition to the rare gas filling, a small pocket 8 is provided on the ring 6 to receive a compound of the material, which evaporates when the lamp is heated to vaporize the getter. When the lamp cools the getter deposited on the neck absorbs the gas or vapour. Specification 369,987 is referred to.

1,009,700. Tying bag necks. FMC CORPORATION. Sept. 25, 1963 [Oct. 5, 1962], No. 37643/63. Heading B8C. [Also in Division B3] After the neck 20a (Fig. 2) of a bag has been gathered against a stop 68, a tie 100 is applied to the neck by movement in the same direction as the bag to overtake it. In the form illustrated the tie 100 is carried by a double-armed lever 70 which also carries notches 68 forming the stop. When a mechanical sensing device indicates that the package 20e has reached the position where the bag neck is fully gathered, the arm 70 is rotated through half a revolution to apply the tie 100 : immediately before this a spring-biased stop 96 is positioned against the gathered bag neck. The package is carried on an endless belt (not shown) and the neck is flattened and fed firstly by guides 54 and subsequently by rollers 50, 52 whose peripheral speed is the same as that of the belt. One of the rollers may be grooved to fit into the other, which may be surfaced with a friction material. The tie is subsequently twisted by jaws 110 (see Division B3) which advance towards the tie, grip it and twist it, release it, and are then retracted and rotated in the opposite direction. Each tie may consist of a wire 194 (Fig. 13) sealed between two strips 196, 198 of paper. The ties are fed from stock 192 (Fig. 2) by rollers 202, 204, to lie across the notch 102 in the lever 70. The tie is then cut from the stock by a guillotine 244 and immediately afterwards is pressed into the notch 102 by a shaping finger 262. The devices for feeding the tie stock, and for applying and twisting it, together with the equipment for gathering the bag neck, may be formed as a unit separate from the conveyer carrying the filled bags, and the unit may be pivoted to permit its use in conjunction with a laterally inclined conveyer.

Ethylene polymers in powdered form
|
en
|
An ethylene polymer in powdered form is obtained by polymerizing ethylene with/without other monomers, in a tubular zone at elevated temperature and pressure in the presence of a free-radical initiator, the process being characterized in that the reaction mixture is cooled to a temperature such that the temperature of the polymer after reduction of pressure is below the melting point of the polymer (e.g. cooled to below 110 DEG C., for instance to about 80 DEG C.), following which the cooled reaction mixture is withdrawn from the reaction zone, the pressure is reduced and ethylene polymer in powder form is recovered at a temperature below the melting point. The powder may be from 20 to 100 microns.

[Also in Groups XI and XVII] A cooking vessel is provided with an inner cooking wall surface 20 made of a relatively hard material of relatively poor heat conductivity, an exterior layer 24 of an aluminium containing material which is an excellent heat conductor but which cannot readily be metallurgically bonded, i.e. with surface alloying, to the hard material and an intermediate layer 21 consisting of a third material disposed between and forming a good metallurgical bond with both of the two materials and the vessel includes a heating element 13 embedded in the exterior layer. The vessel has, in an embodiment, an electric heating element 13 embedded in the bottom thereof, a handle 12, insulating support legs 17 and a plug receptacle 16 for a power supply and possibly a temperature control device. In making the vessel a composite sheet formed of a sheet of stainless steel 20, 7-12 thousandths of an inch thick, rollbonded or brazed to a sheet of copper 21, 6 thousandths of an inch thick, is deformed to form the body of the vessel with the stainlesssteel on the interior. The copper is cleaned in acid, possibly after abrading, and the composite sheet is placed in a mould 25, 26 in the upper part 26 of which a sheathed heating element 13 is suspended. Aluminium or aluminium alloy is supplied to the mould in a gravity die casting process at a temperature of 1200-1500‹ F. or in a pressure die-casting process at a temperature of 1150-1400‹ F., the dies in this case being initially heated to 500- 650‹ F. to heat the composite sheet. The aluminium layer 24 cast on to the copper of the sheet may have a thickness of #th inch. The mould may include recesses such that integral cast leg supports are provided or tapped leg supports may be placed on the copper surface and secured in position by the cast metal. Alternatively, the cast aluminium may be drilled and tapped to receive the legs. An alluminium alloy containing Cu, Fe, Si, Mn, Zn, Ni, Sn and Mg may be used. The stainlesssteel may be replaced by titanium &c. and the copper by another metal.

The polymerization of ethylenically unsaturated monomers is effected in the presence of ethylene-diamino tetraacetic acid, diethylene triamino pentaacetic acid, nitrile triacetic acid and/or one or more of their water-soluble salts in an aqueous medium having a pH of not more than 4 using a Redox catalyst system comprising chlorate ions as catalyst and reducing sulphoxy ions as activator and in the absence of molecular oxygen. The monomer is preferably acrylonitrile and is present in at least 80% by weight. Other monomers used in up to 20% by weight include aryl olefines, acrylic acid, substituted acrylic acid, their esters, nitriles, and amides, unsaturated ketones and monomers containing an acid function to improve the dyeability of the polymers with basic dyes. The nitrogen-containing organic additive may be present in less than 5% by weight of the initial monomer. As watersoluble salts of these additives that may be used are the di-, tri- and tetra-sodium and potassium salts, the mono- and bi-calcium and magnesium salts, the di-, tri- and tetra-ammonium salts and mixtures thereof. The chlorate ions may be present in from 0À1 to 2% by weight and may be supplied by the addition of a water-soluble ammonium, alkali, alkaline earth or heavy metal chlorate. The reducing sulphoxy ions (these are sulphur compounds in the form of ions or capable of forming ions in the polymerization medium in which the valency of sulphur is not more than 4) are formed by the addition of water-soluble sulphites, bi-sulphites and meta-bisulphites of ammonia, alkali, alkaline earth or heavy metals, or sulphur dioxide, or water-soluble dialkyl sulphites. The molar ratio of catalyst to activator is preferably less than 1 : 6. The polymerization may be conducted in a batchwise, semi-continuous or continuous way preferably at a temperature of 20-70‹ C. In the examples: (I) acrylonitrile, (II) 91% aorylonitrile, and (a) 9% methyl acrylate, or (b) 9% vinylacetate, and (III) 90À5% acrylonitrile, 9% vinyl acetate and 0À5% sodium p-methyl allyl ether are polymerized in the presence of ethylene diamino tetra-acetic acid, and (IV) acrylonitrile is polymerized in the presence of nitrile triacetic acid.

Preferably the control unit is arranged so that switching over of the operating channel to the substitute channel does not take place solely on the basis of the signal to noise level but occurs only when the pilot signal is absent. It is also preferably arranged that a switch back to transmission of the information signal to the operating channel from the substitute channel takes place immediately after the operating channel becomes serviceable again.

845,892. Fuel injection pumps. PRECISION MECHANIQUE. Dec. 21, 1956 [Dec. 23, 1955; May 25, 1956], No. 38959/56. Class 102(1). [Also in Group XXIX] A fuel injection pump comprises a pump piston 1 Fig. 1, driven from the engine which delivers fuel through conduit 3, non-return valve 5 and conduit 4 to the engine cylinder, the end of the effective stroke of the piston being controlled in the normal way by a groove 9 on the piston. The conduit 3 also leads by a conduit 32 to a valve chamber 14 housing a spring loaded valve member 13 having an axial passage 20 which opens at the upper end into a groove 24 and at its lower end into a groove 22 of variable depth. A piston 15 secured to the pump piston 1 reciprocates in a cylinder 16 and pumps liquid through conduit 17 to a chamber 23 and then through the variable groove 22 to the axial passage 20. By rotation of the valve member 13 the variable groove 22 provides an adjustable throttle for the flow of liquid to the axial passage 20. As the speed of the engine and hence the pump increases the liquid delivered by piston 15 causes the valve 13 to rise on each stroke of the piston and the groove 31 in the valve connects the conduit 32, leading from the delivery passage 3, to a by pass 33 thus providing a control of the quantity of fuel injected in accordance with engine speed. The valve 13 may be provided with a groove connecting the conduits 32, 33 in a certain angular position of the valve as a safety precaution when the engine is stopped. The liquid delivered by the pump 15 may be led to passages in the top of the valve. The invention may also be applied to an injection pump which feeds to more than one cylinder in which the piston 1 reciprocates and rotates and is provided with a groove communicating in turn with each outlet as in Figs. 9 and 11, (not shown), in this case the valve may have suitable passages which lead to grooves on the piston for determing the effective stroke. In the embodiment shown in Fig. 15 where the piston 1 reciprocates and rotates and delivers to the cylinders through a plurality of outlets 4, the valve member 13 is provided with a recess 63 having an inclined edge 64 so that by rotation of the valve 13 the distance h through which the valve must move to connect the conduits 32 and 33 may be varied. Specification 669,762 is referred to.

Improvements in or relating to electrically conducting articles
|
en
|
An electrically conductive article comprises a support body having a smooth continuous surface, a metal compound forming an adhesive layer on said surface. a film of gold, silver, copper, iron or nickel on said metal compound layer, a metal compound forming a second adhesive layer on the film of gold &c., and a film of chromium or nickel on the second metal compound layer. The support body may be a glass or plastic lens or window of a vehicle or instrument, the coating being applied so that the article can be heated to reduce fogging or icing. The metal compound layers may be composed of oxides, sulphides or sulphates; they may be applied by direct thermal evaporation, by first evaporating a metal on to the support and then oxidizing, or by sputtering a metal in a vacuum containing residual oxygen. The metal films may be deposited by thermal evaporation. A protective layer, e.g. of quartz, alumina or magnesium fluoride, may be deposited on the chromium or nickel film, and electrodes may be placed on opposite edges of the support body either before or after applying the protective layer. The coated article is preferably baked, e.g. at 350 DEG -625 DEG F. Specifications 605,871, 605,889 and 682,264 are referred to.

919,879. Measuring temperature electrically. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 23, 1959 [Nov. 26, 1958], No. 39656/59. Class 40 (1). A method of measuring the temperature of molten metal in a bath using a thermo-couple comprising two separated wires of dissimilar metals enclosed within a metal envelope, with the interposition of inorganic insulating material between one pair of ends of the wires and between these ends and the wall of the envelope, the metal envelope having a melting pointlower than that of the molten metal, comprises dipping the end of the thermo-couple in the molten metal in the bath so that the envelope melts and the molten metal in the bath establishes an electrical connection between the ends of the wires. The inorganic insulating material can be MgO or Hl 2 O 3 , the metal of the envelope can be nickel, the wires can be of platinum/ platinum-rhodium and the molten metal can be steel. The metal envelope containing the wires is passed through any slag on top of the bath into the molten metal. After use the ends of the wires can be cut off and the metal obtained therefrom.

810,769. Ships with air cushions between hull bottom and the water. GRAM, K. F. Dec. 20, 1957 [Dec. 27, 1956], No. 39669/57. Class 113. In a ship having an air cushion 2 beneath its bottom 1 for reducing friction during forward movement of the ship, the air cushion is connected (by ducts 3, 5) at its ends into a closed circuit. A pump or blower 4 is provided for importing to the air in the cushion a velocity longitudinally of the ship. Air losses are made up from the atmosphere by a small compressor 7 delivering to a pipe 6 leading to the duct 3. The capacity of the pump or blower 4 may be adjusted automatically in dependence on the speed of the ship. The longitudinal velocity of the air in the cushion assists in stabilising the air cushion during moderate rolling but with large angles of roll air will escape at the sides and this can be avoided by providing the ship with means (such as blowers or anti-rolling tanks) for moving the air in the air cushion during rolling transversely of the ship with a periodically changing velocity and direction. In Fig. 2 a small anti-rolling tank consisting of legs 10 and 11 is arranged on each side of the air cushion 2. The tanks and air cushion are connected by air ducts 12, 13, the latter including a regulating valve 14. The system is brought into operation by the rolling of the ship, the air velocity being controlled by adjustment of the valve 14. The time of oscillation of the water in the tanks is made substantially the same as the period of roll of the ship but phase-displaced in relation to the rolling. Similar arrangements may also be made for adjusting the air in the cushion during pitching.

1,110,355. Packaging gaskets; applying adhesive tape. ROLLS-ROYCE Ltd. 7 Sept., 1966, No. 40045/66. Headings B8C and B8F. [Also in Division B5] Adhesive tape 11 is applied to an edge of an inclined sheet 12, e.g. of cardboard when a carriage 15 carrying a roll of tape 18, traverses the length of the sheet. A clamp 36 holds the end of the tape and the sheet. The carriage which applies the tape from left to right (as seen in Fig. 2) to overlap the sheet edge is driven by a motor 31, operating a leadscrew 24 when a carriage microswitch (60), Fig. 3, is in contact with the sheet. When the board has been traversed microswitch 60 switches off the motor and a heating wire 45 carried on a sliding yoke 46 operated by a pivoted beam 52, is moved into contact with the tape which is thus cut from the roll. Movement of the wire is effected by a solenoid 55 energizing to pivot the beam 52. Switches 61, 62, limit carriage movement, and a sensing finger 63 prevents operation of the motor when insufficient tape remains on the roll. After taping, a gasket may be placed between the sheet and an untaped sheet and the tape bent over on to the further sheet by forcing through a slot (29), Fig. 1, in table (33). The remaining edges are similarly taped.

Di-, tri- and higher polymeric monobasic aliphatic acids (8-24 C) are hydrogenated in the presence of a nickel hydrogenation catalyst and then in the presence of a palladium hydrogenation catalyst to improve the colour and reduce the iodine value. The polymeric acids may be obtained by using a clay catalyst and temperature ranges of 150-225‹ C. for the nickel hydrogenation and 175-275‹ C. for the palladium hydrogenation are preferred. Examples describe the treatment of clay polymerized tall oil fatty acids using a Raney nickel catalyst and a palladium catalyst suspended on carbon. An optional acid treatment of the nickel hydrogenated product before the palladium hydrogenation removes nickel salts.

839,535. Drying powdered coal &c. DAVIES, N. L. Dec. 12, 1958 [Dec. 12, 1957], No. 40231/58. Class 34(2) A method of drying finely-divided coal &c. consists in exposing it to hot dry gas first in a preheating zone in which the surface moisture is heated close to its B.P. and then in a drying zone in which the surface moisture is flashed off as vapour. The coal may be treated in a tower having a preheating zone with annular shelves 32, 34, 36, Fig. 2, supported on radial brackets carried by an exhaust duct 28 secured to, and rotating with, a motordriven turret 15 mounted on rollers 13 and forming the tower cover, and a drying zone having rings 50, 51 supported by a hopper 21 having conveyers 22 for discharging the dried coal. The wet coal is fed by a conveyer 8, Fig. 3, along a trough having a hopper 20 at its inner end through which the coal falls on to the upper rotary shelf 32 and is repeatedly turned over and moved towards an annular gap between the shelf and the duct by helical ploughs 48, 49 depending from radial brackets secured to the wall of the tower. From the shelf 32 the coal falls on to the shelf 34 on which it is repeatedly turned over and moved outwards by helical ploughs similar to those provided on the shelf 32. The coal then passes on to the lowest shelf 36 over which it is moved by helical ploughs towards the gap between the shelf and the duct 28. During its passage over the shelves the coal is subjected to the hot gases from a furnace 23, Fig. 4, which pass into the tower in the space above the upper plate 32 through a tangential duct 25 controlled by adjustable dampers 26. The gases flow downwards with the coal until they reach the flared inlet to the duct 28 at which point they pass up the duct while the coal continues to flow downwards through the cylindrical space formed between the rings 50, 51. During its passage between the rings it is subjected to hot gases admitted through a tangential duct 24 to the space around the rings. The gases flow upwards from the drying zone to the exhaust duct 28. Fresh air may be admitted to the bottom of the tower through an aperture controlled by a damper 27.

Process for deodorising and desulphurising materials that contain hydrocarbons
|
en
|
Materials which contain hydrocarbons, for example oils, coal gas, benzene, toluene, and xylene, are deodorized, desulphurized, and purified by contacting them with finely-divided alkali metal oxides and/or hydrides, which may be supported on an inert carrier, for example carbon or sodium chloride, which may be shaped. Sodium oxide pretreated with hydrogen is preferred. Hydrogen may be present in, or be added to, the material to be purified. The contacting may be effected in the vapour phase, desirably at 150-250 DEG C. and at superatmospheric pressure, or in the liquid phase, desirably at room temperature. The preferred contacting time is 80-120 seconds. The alkali metal compounds may be kept in constant motion during the contacting, for example in rotary tubes, stirrer-type worms, or roasting furnaces, or in a fluidized bed.

1,192,414. Lasers. SPERRY RAND CORP. 15 Sept., 1967 [20 Sept., 1966], No. 42198/67. Heading H1C. Mode locking in a ring laser is prevented by arranging the counter-rotating light beams to be identically plane polarized where they pass through the active medium, and to be polarized in different respects in the remainder of the closed radiation path defined by the resonator mirrors. In Fig. 1 a discharge tube 14 contains a helium-neon active medium excited by r.f. applied to electrodes 18, 19, the tube having windows 20, 21 at Brewster's angle for horizontally plane-polarizing the two emitted beams. The optical resonator is formed by mirrors 10, 11, 12, quarter-wave optical plates 23, 24 being located between mirrors 11 and 12, respectively, for circularly polarizing the two counter-rotating beams in opposite respects in the closed optical path external to the active medium. The direction of circular polarization of each beam is reversed at each reflecting surface, and at no point in the resonator are the respective polarizations such that mode locking by back scattering can occur. Extraction of the two beams is effected at partially-transmitting mirrors 10, 12, respectively, the two beams being combined and applied to a photo detector 26 in the same polarization sense by a mirror 41 and a beam splitter 40. A frequency bias is introduced into the closed optical path by a magnetic-optic birefringent member 22 which, in combination with the circular beam polarizations produced by the quarter wave plates, produces different effective path lengths for the two directions around the resonator. In a modification, Fig. 2 (not shown), the mirrors 11, 12 are replaced by totally internally reflecting prisms (38, 39) each in contact with and located between a Brewster's angle window and a quarter wave plate. Energy extraction in the Fig. 2 and Fig. 3 embodiments is by a single partially-transmitting mirror 10 in conjunction with a reflector 28 and an analyser 25. The Fig. 3 arrangement has the Brewster's angle windows positioned so as to polarize the beams midway between the vertical and horizontal planes, and Faraday rotators 43, 44 are used to rotate the polarizations of the clockwise and anticlockwise beams through 45 degrees to the horizontal and vertical planes respectively in the closed optical path external to the active medium. Frequency bias is obtained by using a natural or electro-optic birefringent member 47 having its orthogonal principal axes S, F aligned parallel to the horizontal and vertical beams. In each embodiment, a polarization change due to one quarter wave plate 23, 24 or Faraday rotator 43, 44 is cancelled out when a beam passes through the second plate or rotator.

1532077 Automatic control CHEMETRON CORP 12 Oct 1976 [7 Nov 1975] 42299/76 Heading G3N The temperature rise of an article heated in a micro-wave oven is controlled by setting the actual initial temperature and the desired final temperature of the article, at 66 and 64 which generates a threshold at IC-3, and then integrating, at IC-2 a signal representing electrical field strength in the cavity until the threshold is reached, at which time the desired temperature should have been reached and the power is switched off. The signal which represents field strength is modified before integration by subtracting a constant to compensate for the reduction in efficiency of the heating effect when large articles are heated, and the integral is normalized for efficiency of absorption of the radiation. A timing circuit IC-4 prevents operation of the oven for longer than a predetermined maximum time and protection is provided by the Zener diode CR7 which switches the oven off in response to an upper limit of field strength representing an empty cavity.

1527595 Modulation transfer function of an optical component SIRA INSTITUTE Ltd 22 Dec 1975 [30 Sept 1974] 42341/74 Heading G1A Apparatus for measuring the modulation transfer function of an optical component comprises a source of electromagnetic radiation, a MoirÚ fringe generator having two linear gratings with their planes parallel but not their lines and being linearly moveable relative to one another, a detector arranged to receive radiation via the generator and the component, and an analyzer of its output for determining the function. The source, of nickelchromium wire on a ceramic cylinder electrically heated to 1000 K is followed by a germanium condenser lens and a filter. A source of visual wavelength may be used instead. A collimator lens and the component being tested image the radiation on to a slit on the detector 16 via a 100Hz chopper. One grating is circular and the other rectangular and slidable normally to it lines and reciprocated by a stepping motor, both being rotatable about the axis of the circular one in the opposite sense to change the spatial frequency but not the orientation of the fringes. The detector 16 is connected to an analyser as shown in Fig. 3, where 43 is a phase sensitive rectifier and 42, 45, 47 and 57 are band, low, high and low pass filters respectively and meter 52 indicates modulation transfer function.

1,172,986. Brake adjusters; cams. GIRLING Ltd. 6 Sept., 1967 [26 Sept., 1966], No. 42840/66. Headings F2E and F2K. In a brake adjuster mechanism, particularly for drum brakes, a rotatable cam 3 is provided with a cam surface in the form of a helix, preferably an Archimedean Helix, decreasing in diameter from one end towards the other and cam followers, in the form of brake shoe engaging tappets 4, arranged for relative movement along the helix so as to be displaced transversely of the axis of rotation of the cam. The cam is rotatably supported at its ends in an adjuster housing 1, the upper end portion 2A of the cam member being plain and circular and journalled in the housing while the lower end portion 2B is screw threaded into a bush 6 keyed to the housing by a peg 7, the cam being adapted to be rotated by means of a projecting spindle 8 having a squared end 9. The upper end portion 2A may be formed with a plurality of axially directed notches for the co-operation of one or more click springs (not shown) which afford stepwise adjustment of the cam. The inner ends of the tappets which engage the cam surface 3 may be shaped to have single line contact with the surface or may be generally V- shaped and profiled at each side of the V to have a two-line contact with the surface throughout the rotation of the cam. Several modifications are disclosed in the Specification, but not illustrated, for example the screw threaded members could be eliminated by spring-urging the cam axially to bring the axially facing shoulder of the helix to bear against the sides of the tappets. In an alternative arrangement the cam member may be rotatable but fixed axially and a separate, axially movable cam follower is interposed between the cam and the tappets. In a further modification the cam may be of other than an Archimedean Helix form and the tappets may not have constant velocity for constant cam angular velocity.

911,098. Drafting-apparatus. SKF. KUGELLAGERFABRIKEN G.m.b.H. Dec. 16, 1960 [Dec. 17, 1959 ; Oct. 20, 1960], No. 43356/60. Class 120 (2). In double-apron drafting-mechanism where a bridge-guide for the lower apron is at least adjustable transversely of the drafting-field and is detachably connected by a fixing member, e.g. a screw 14, to a fixed part of the machine, the guide 10, Fig. 2, is rigid and is located relatively to the fixed part 1, e.g. the bearing- bracket in which the lower rolls are mounted, through positioning members 16, Fig. 3, which can be exchanged to vary the position of the guide and which are secured by the screw &c. 14 which connects the guide to the fixed part 1. As indicated in Fig. 2, a lower apron 11 and a guide 10 are arranged on either side of bracket 1 ; one set of members 16 serves both guides at each bracket and each member 16 is slotted to receive a screw 14. Each guide has downturned parts 10<SP>1</SP>, Fig. 3, which engage the sides of a recess either in the bracket or a member secured to it by the screw 14, and inclined parts 10<SP>11</SP> to guide the apron. A block 15 may be provided between the guide and the members 16 and one or other of these parts may be magnetized to hold them together when they are removed. In an alternative form, Fig. 4, the bracket has ribs 19, co-operating with the members 16 which take the form of curved strips 16<SP>1</SP> which may be such as to permit the guide to be canted. To enable the position of the guide to be adjusted e.g. along the line of draft, the screw 14 may extend through a slot either in the guide or the holder above referred to; in the former case, the ends 10 do not extend as far as the sides of the recess in the bracket and the guide and the block may have co-operating ridges, Fig. 8. To permit the guide to be accurately positioned, markings may be provided on the bearing bracket 1, or on the locating means in Fig. 8.

948,077. External shoe drum brakes; fluid pressure control of brakes. G. A. BLACK. Dec. 16, 1960 [Dec. 21, 1959], No. 43374/59. Headings F2E and F2F. An external shoe drum brake for winding apparatus is applied by springs and released by fluid-pressure, and comprises two separate spring units for applying the same brake in a winding mechanism, means opposing the force exerted by one of the units being provided whereby this unit may be held out of operation while the other is being actuated, and means whereby both units may be operated together to produce a braking force equal to the sum of the braking forces derivable from each unit. In one embodiment, the brake comprises two spring units 6, 7, Fig. 2, carried respectively by shoes 1, 2 pivoted at 3, 4 for movement into and out of engagement with a drum 5. Each of the units 6, 7 acts on both shoes through levers 8, 9 pivoted on the respective shoes and linking rods 10, 11 each independently adjustable for wear by nuts engaging threaded portions of the rods adjacent their connecting points. One rod, i.e. the rod 11, is connected at the end remote from the corresponding spring unit 6, via a lost-motion connection 12, 13 to the opposite shoe 2. Each spring unit comprises a set of springs for applying the brake and a pair of cylinders which act against the springs to release the brake. Oil is supplied by pumps 21, Fig. 5, via non-return valves 29 and by-pass 22 to a control valve 23 which acts to pass oil either directly to and from the pairs of cylinders in both units 6, 7 associated with each of two winding drums, in one position, or in the other position to pass oil directly to and from the cylinders in units 6 but via non-return valves 23b to the cylinders in units 7 so that these units are held off. Either both units 6 and 7 or just the units 7, according to the position of valve 23, are further controlled by a driver's regulator valve 24 for varying the oil pressure between the maximum and zero, at which latter maximum braking is obtained. A trip valve 25 can be opened in an emergency to give maximum braking instantly. The valve 23 is operated by a solenoid or automatically according to the direction of movement of the winch drums so that, e.g. where the position of one cage in a mine shaft is adjusted relative to another, so that the cages are temporarily unbalanced requiring greater braking force to hold the respective winding drums, the valve 23 is moved to a position in which both units 6 and 7 are operative. In normal use the two cages are balanced and are moved together in opposite directions so that lighter braking, provided by moving the valve 23 into its other position in which units 7 only are operative, is all that is required. In order to cope with failure of the units 7 should e.g. a link rod break, the cylinders of the normally inoperative units 6 are arranged to be automatically connected to the oil feed to the cylinders of the units 7 via an annular port way 26 in each cylinder of unit 7, and a port way 27 in the associated piston which communicates by a passage 28 with the pressure side of the piston, the arrangement being such that the port ways 26 and 27 are aligned should the piston overstroke. The corresponding unit 6 is then placed under control of the driver's valve so that braking is restored. In a modification, Fig. 6, separate control valves 32 are used for the pairs of units 6, 7 associated with the respective winding drums, each movable between the position shown, in which oil is supplied direct to the associated units 7 and via non-return valves 35 to the associated units 6 so that the latter are held off, and another position in which d, e and c are interconnected for exhausting the cylinders of the associated units 6, 7, and a, f are connected in place of a, b, so that each valve supplies oil direct to both pairs of units 6, 7 of the other winding drum so that maximum braking on either drum can be doubled while still under control of driver's valve 33, the brake being held by both units 6 and 7 on the other drum independently of driver's valve 33. Solenoid valves 39 may be added if desired so that double braking can be used on both winding drums while retaining driver control. The cylinders of units 7 again have provision for coupling units 6 to the driver's valve should their pistons overstroke, so that, in the normal condition with only units 7 operative, braking is automatically restored by units 6 should a link rod associated with units 7 break. In a modification of the brake itself, Fig. 7, the units 6 and 7 are mounted side by side on one of the two brake shoes and coupled through levers 40, 41 on that shoe and link rods 42, 43 to the other shoe. Operation of the brake is identical with that shown in Fig. 2 since each spring unit operates both shoes as before. In a further modification however, Fig. 10, the units 7 are replaced by units 44 acting separately on the shoes 1, 2 so that they may be controlled independently to provide further control of maximum braking, while a unit 45 is mounted on shoe 2 and is connected by lever 46 and link rod 47 to the shoe 1 to provide emergency or additional braking as did the units 6 in the previous embodiments. The shoes 1, 2 in this embodiment are pivoted at 3, 4 on sliding blocks adjustable by screw-and-nut mechanism. Specifications 691,941 and 782,023 are referred to.

In a back-hoe bucket excavator means are provided between the chassis 20 and the boom 24 of the excavator to positively prevent upward movement of the boom whilst the bucket 27 is digging into material and yet automatically allow upward movement of the boom as the bucket moves from the digging to a discharge position. The means may be hydraulically or mechanically actuated in response to the tension in the drag rope 31 of the excavator. The drag rope 31 either acts on a linkage operating a rotary valve controlling flow of liquid under pressure to and from an hydraulic jack 62 extending between the mast structure 43 and boom 24 of the excavator or a brake band of a brake drum associated with a gear-wheel mounted in the mast structure and co-operating with a toothed rack extending to and secured to the boom. -

970,660. Gas turbine plant. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 20, 1962 [Dec. 6, 1961], No. 43717/61. Heading F1G. [Also in Division G3] A control system for a gas turbine power plant comprises means providing an indication of the temperature of the gases flowing through the turbine, means sensitive to that indication and upon occurrence of an excessive temperature acting to reduce the supply of fuel to the combustion chamber, there being also means providing an indication of the speed of the gas turbine and means arranged in accordance with that indication to effect suitable adjustment of the means acting to reduce the supply of fuel to the combustion chamber so that during starting up of the gas turbine plant, a rate of fuel supply to the combustion chamber is allowed which would be excessive for normal full speed operation. The plant shown comprises an air compressor 1, combustion equipment 11 and a turbine 5, an electrical tachometer 7 being mounted on the compressor-turbine shaft 3. Fuel is supplied to the combustion equipment through line 17 through control valve 19, the valve being connected at 39 to an E.M.F. comparison unit 35. Thermocouples or groups thereof are disposed at 21 at the outlet of the combustion equipment and at 23, 25, 27 at spaced locations along the gas flow path through the turbine. Signals from the thermocouples are passed through lines to the electronic scanner 31 which selects each of its inputs in sequence and applies the selected input to the unit 35 through lead 33. A signal indicating turbine speed is also passed to the unit 35 from the tachometer 7 through line 37. The comparison unit 35 repeatedly compares the selected signal applied through lead 33 with a reference signal and if the signal applied through lead 33 indicates an excessively high temperature the unit acts to adjust the valve 19 to reduce the flow of fuel. During starting, it is permissible to operate at temperatures which would be excessive for continued operation and the reference signal therefore has a high value. As the turbine approaches its normal speed, the signal from the tachometer acts to change the reference signal to a lower value. The unit 35 will thereafter act to reduce the rate of fuel flow at lower temperatures at the points monitored by the thermocouples. In place of thermocouples, there may be means which sense the air and fuel flows and provide an indication of the air/fuel ratio and thus the temperature attained in the combustion chamber. Again in place of a tachometer the means providing an indication of the speed of the gas turbine may comprise a device sensitive to the pressure of the gas stream through the power plant at a suitable point; alternatively, it may comprise a device sensitive to the fuel pressure at a point in the fuel supply system at which the pressure varies in a suitable manner with the turbine speed.

New products derived from starch
|
en
|
A cooled mixture of starch or flour, having not substantially less than its ordinary equilibrium moisture content, and a substance which will promote gelatinization of the starch granules is mechanically sheared, the consistency of the mixture being such that the shearing forces disrupt the starch granules, and the magnitude and duration of the shearing forces being sufficient to produce a product which exhibits rubbery or plastic-like properties. The process may be applied to wheat starch or wheat flour containing e.g. 12-13% moisture. The gelatinization-promoting substance may be glycerol, ethylene glycol, propane-1; 3-diol, butane 1;4-diol, aqueous formaldehyde; phenol, glyceryl monoacetate, 2-amino-propane-1;3-diol, pyrogallol, phloroglucinol, aniline, catechol, resorcinol, hydroquinone, butane-2; 3-diol, water, dihydroxyacetone, diethanolamine, oxalic acid, dimethylol urea cyclohexane 1;3-diol and formamide. The flour or starch is mixed with the gelatinizing agent and fed into a machine, preferably having a grinding or similar action, capable of exerting strong shearing forces. The reaction mixture may be cooled by an external bath to prevent charring. The proportions of starch or flour and gelatinizing agent are chosen so that a substantial degree of resistance to the machine is provided. For example, the proportion of water or glycerol, when used, should not exceed 20% by weight, giving a mixture which is still a free-flowing powder. In an example, a mixture of raw flour or wheat starch (85%) and water or glycerol (15%) is masticated in a vertical masticator (uni-rotary mixer) for 0.5 hours, the reaction mixture being cooled by a cold-water jacket. Residual gelatinizing agent may be removed from the resulting plastic or rubbery mass by extraction with a solvent e.g. alcohol. The product may be used as a baking additive, edible packaging material, and on the formulation of plastic compositions, detergents, adhesives, paper, textile sizes and coating compositions.

1362213 Vibrators VULCAN IRON WORKS Inc 28 Sept 1971 [10 Dec 1970] 45219/71 Heading F2X A linear vibrator comprises a piston member 50 reciprocal within bores 18a, 20a defined in a cylindrical body 12 and including an elongated rod with an enlarged diameter radial piston 52 midway between opposite ends of the rod. A pair of piston-rings 54 are mounted on the piston 52 which reciprocates in a large diameter bore 18a of a central expansion cylinder 18 of the body 12. The rod end sections or piston-rods 56 each have a plurality of piston-rings 58 adjacent their outer ends and slide in the bores 20a of compression chambers 20 of the cylindrical body 12. The body 12 terminates in heads 16 secured together by tension rods 22, and the lower head (not shown) is provided with a pair of coupling jaws. The vibrator is supported from a cable or pin by means of a clevis (not shown) attached to a support plate mounted on the rods 22. Stacks of spring washers (or coil springs) are provided on the rods 22 on either side of the support plate 40. The inner ends of the chambers 20 are formed with annular recesses 20c housing sealing ring assemblies 64 which seal opposite ends of the expansion cylinder bore 18a. Pressurized fluid from a supply line 70 passes via a feed passage 19 to annular passages 20d formed in the chambers 20 coaxially and outwardly adjacent the sealing ring recesses 20c. As shown, with the piston member 50 in its uppermost position, the pressurized fluid can flow from the upper annular passage 20d via passages formed by flats 56b in the upper pistonrod 56 to the expansion cylinder 18 above the piston 52, forcing the piston member 50 downwards. The supply of pressurized fluid is cut off when the upper flats 56b fall below the upper sealing ring assembly 64 and the fluid in the cylinder 18 then further expands adiabatically until the piston 52 exposes a pair of exhaust ports 18b in the wall of the cylinder 18. During the downward stroke, the fluid entrapped in the lower chamber 20 below the lower piston-rod 56 is being compressed and acts as an air spring with a cushioning effect. When the fluid being compressed attains a sufficient pressure, downward movement of the piston member 50 is stopped and the compressed cushioning fluid begins to expand and move the piston member in the upward direction. In the lowermost position of the piston member 50, flats 56b on the lower piston-rod 56 are adjacent the lower sealing ring assembly 64 so that pressurized fluid may enter the expansion cylinder 18 below the piston 52. The rate of reciprocation and the forces developed by the vibrator are controlled by supplying pressurized fluid to the opposite ends of the chambers 20 from a feed pipe 78 through a bore 18e defined in the expansion cylinder 18 and communicating with the chambers 20 by inclined bores 20g in the walls of the latter. Annular resilient shock-absorbers 60 provided in the heads 14, 16 are used only for safety purposes in case too great a pressure is used on the power side of the system.

1,132,751. Centrifugal pumps; turbines. WORTHINGTON CORP. Oct. 26, 1965 [Feb. 24, 1965], No.45226/65. Headings F1C and F1T. A submersible centrifugal pump for pumping ballast water from a compartment of a ship comprises an impeller 28 which draws the water through an inlet passage 12 and delivers it via a diffuser passage 50 to an outlet 55 connected to a rising main. The pump is driven by a turbine comprising rotor blading 30 formed on the impeller 28 or otherwise connected to it. An auxilary pump located above the compartment delivers water via a downpipe and an inlet passage 16 to nozzle vanes 33 and thence through the turbine rotor blading 30 to drive the turbine. On leaving the blading 30, the water enters the diffuser passage 50 to join the water discharged by the impeller 28 and to exert an ejector effect which assists the pumping action. The diffuser vanes 54 have projections adjacent the rotor blading 30 to form ejector vanes. Alternatively, separate ejector vanes may be used. The diffuser passage 50 reduces the fluid velocity to minimize the losses incurred in passing around the obstacles 16, 24. Thereafter, the velocity is increased towards the outlet 55. The turbine may be driven by a liquid different from that being pumped. The two liquids thereby mixed together may subsequently be separated in a settling tank or a centrifuge. Alternatively, the turbine may be driven by steam which condenses and mixes with the pumped water. The turbine nozzle may be of partial admission type. The impeller 28 may be carried by a shaft journalled in a bearing. Alternatively, it is carried by a bush 66 which is journalled on a stationary shaft 27, either directly as shown or through the intermediary of ball bearings. Lubricant, which may be the fluid being pumped and may be cleaned by passing it through a cyclone separator, is supplied through passages 81, 82, 83, 84 into chambers 85, 85' formed by flats 61, 62 on the shaft 27, and returns to the pump inlet via the clearance between the bush 66 and a thrust collar 69 and also via passages 90. In an alternative arrangement, Figs. 18-20 (not shown), the pump discharges through a volute (201), while the turbine driving fluid is admitted through a centrally disposed inlet (200) at the top of the casing.

A shield 8 is positioned near the cathode Y of an ionization manometer to shape the field so that electrons emitted by the cathode are directed towards a cylindrical grid 5 surrounding a central ion collector 3, the cathode 7 being positioned outside and adjacent to one side of the grid. The shield 8 which is preferably maintained at the same potential as the cathode 7 (e.g. 50 volts) may be a solid or perforated plate or a grid, and may be semi-cylindrical or straight-sided as shown. The emitted electrons follow paths such as 9 through the grid 5 which may be maintained at 150 volts. A conductive transparent coating on the inner surface of the envelope 1 is maintained at the same potential as the ion collector 3 (e.g. 0 volts). Alternatively the envelope 1 may be replaced by a cylindrical metal grid, the manometer being mounted directly in a vacuum system to be measured.

1278138 Spray producers ATLAS COPCO AB 25 Sept 1970 [6 Oct 1969] 45690/70 Heading B2F A hand held spray gun has spraying material supplied to it through a hose 16 from a receptacle 19 including an ejector 24, the ejector tube 20 being supplied with compressed air via a pressure reduction valve 18, the degree of pressure reduction being controlled by a trigger 14 on the gun via a second pressure reduction valve 31 in the gun, this being supplied with compressed air by a conduit 15 and connected to a balance chamber 29 in the first pressure reduction valve by a conduit 17. The first pressure reduction valve 18 is supplied with compressed air from a conduit 22, a valve body 25 connected to a diaphragm 21 urged against a valve seat 26 by a spring 27, preventing the flow of gas to chamber 28 and the ejector 24 unless there is compressed air in the balance chamber 29 acting against the diaphragm 21 to open this valve. The pressure of air from the conduit 17 in the chamber 29 also determines the size of chamber 28 as a result of the movement of the diaphragm 21 and consequently controls the amount of pressure reduction in valve 18 and so controls the pressure of air supplied to the ejector. The pressure of air in conduit 17 is controlled by the trigger 14 acting through an adjusting spring 6 and a valve lifting finger 18 on a valve body 8, the degree of compression of this adjusting spring 6 determining the pressure of air delivered from conduit 15 to conduit 17 and thus the trigger 14 determines the flow of spray material from the ejector 24. A fine pressure equalisation opening 30 in balance chamber 29 allows the release of pressure from this chamber. In the embodiment described the spray material is charged electrostatically, this being by way of a high voltage supply cable 9 to the gun. The gun may be used to spray such materials as paint powder, concrete, fiber cuttings, sand and steel blasting grit. When the gun is not adapted for electrostatic spraying the spray may be assisted by auxiliary pneumatic spray nozzles at the tip of the gun.

1534556 Electronic timepieces DAINI SEIKOSHA KK 10 Nov 1976 [11 Nov 1975] 46800/76 Heading G3T An electronic timepiece functions as a stopwatch and also to selectively indicate time in two different time zones, all indications being on the same digital display devices (e.g. liquid crystal). In Fig. 1, a frequency divider 2 supplies 1 Hz timing pulses, derived from a crystal-controlled oscillator 1, to three sets of secs, mins and 24 hour counters 4, 5, 6 and 8, 9, 10 and 14, 15, 16. One set, e.g. set 3, may be for GMT; set 7 may be for time of day in another time zone, and the remaining set is for chronograph time. A switching circuit 20 (detailed Fig. 6 not shown) including a ring counter, stepped by each closure of a manually operable switch, produces three outputs to selectively control three sets of transmission gates in each of circuits 17, 18, 19 (as detailed in Fig. 8 not shown) whereby to couple a selected one of the counter sets to a decoderdriver circuit 21 for display of the contents thereof on a common display unit 22 which comprises 7-segment type display devices. A circuit 11 is for setting the time of day counters to the correct time. A circuit 13 is a switching circuit (detailed Fig. 4 not shown) including ring-connected flip-flops stepped by a manual switch to produce control signals for chronograph operation. One signal controls an AND gate (42) to start and stop the supply of 1 Hz pulses from the divider to the chronograph counters; the other functions to reset the chronograph counters to zero.

1,209,025. Target detection and location system. ELECTRIC & MUSICAL INDUSTRIES Ltd. 23 Oct., 1967 [21 Oct., 1966], No. 47413/66. Heading H4D. General.-The Specification describes a withinpulse frequency modulated radar or sonar target detection system, wherein each pulse, e.g. 0À1 sec. long, is divided into intervals during which it has a constant frequency, no two intervals having the same frequency. All described embodiments are sonar systems transmitting pulses having the frequency variation shown in Fig. 1A. The order of frequencies is selected by quasi-random and the frequencies are separated by equal amounts (90 c/s.). Generation of the pulse is such that the phase from one interval to the next is continuous (Fig. 1B). The echo of the pulse is detected by matched filter techniques or by correlation techniques, Doppler shift also being detected. Production of pulse.-Four methods of producing the transmitted frequencies are described:- (A) Fig. 2. The frequencies present in the pulse centre around 9900 c/s. and are: 9540 c/s.; 9630 c/s.; 9720 c/s.; 9810 c/s.; 9900 c/s.; 9990 c/s.; 10,080 c/s.; 10,170 c/s.; 10,260 c/s. A generator 1, thus produces a frequency of 9000 c/s., and this is fed to an upper side band mixer 30 for selective mixing with the frequencies 540 c/s. &c. produced by mixers 9/12. " By 10 " divider 2 produces a 900 c/s. signal which is fed to one input of each of the mixers 9/12. Frequencies of 90 c/s., 180 c/s., 270 c/s. and 360 c/s. are produced by divider 3, and multipliers 6, 7 and 8 respectively and are fed to the second inputs of respective mixers 9/12. Upper and lower side band products together with the output of divider 2 provide the required range of frequencies 540 c/s. to 1260 c/s. A resetting pulse train of 10 p.p.s. is produced by divider 4 and this is fed to reset a 9-stage shift register 5 shifted by the 90 c/s. output of divider 3 such that a signal appears at each stage of the register in succession for periods defining the interval of the pulse, Fig. 1A. The 540 c/s. to 1260 c/s. range of frequencies are fed via respective gates 21/29 to a combined second input of mixer 30. The gates are opened in the correct order to produce the frequency variations of Fig. 1A, by the outputs of the register, by means of a " random " selection matrix, whereby a selected register stage output is connected to a selected gate. The pulse output of mixer 30 is fed to a transmitting transducer, via gate 32 enabled for 0À1 sec. every 30 sees. (B) Fig. 3. Each frequency 9540 c/s. &c. is generated directly by an oscillating circuit 35 including turning capacitors 51/59. The " random " selection matrix connects each capacitor in turn to the oscillating circuit, according to the predetermined programme. (C) Fig. 4. Each frequency 9540 c/s. &c. is produced by dividing the 1À09 Mc/s. output of oscillator 1 by corresponding factors of 114, 113, 112 . . . 106, by means of binary divider chain 60. Use of all the stage of divider 60 gives a division of 128 and to produce the lesser factors in the required order, selected ones of the stages are preliminarily reset by the output of the chain under the control of signals from the selection matrix enabling the selected ones of gates 62/66 feeding the output of the chain to the resetting inputs of the stages. (D) Fig. 5. The selection matrix is omitted, and the pulse is continuously generated by mixing a 9000 c/s. signal with the output of a frequency synthesizing network, comprising a 300-stage shift register 70 shifted along by a 300 c/s. signal in 0À1 see., each stage output being connected via a weighting resistor to a combining amplifier 75. Thus, the 540 c/s.- 900 c/s. - 1260 c/s. - 630 c/s. &c. signal required to produce the frequency variation of Fig. 1A is synthesized as comprising 300 portions each 1/3000 sec. in duration and having amplitude determined by the weighting resistors. Detection of echo.-Several methods of detecting the echo and extracting Doppler information are also described:- (E) Fig. 6. The received echo is heterodyned down to a centre frequency of 900 c/s. by means of oscillator 104 and mixer 103 and is then fed to a transversal filter comprising a tapped delay line 105. If no Doppler shift were present a single channel of suitable weighting resistors connected to respective tappings would produce an output from combining amplifier 107 and threshold device 108 on reception of an echo of the pulse of Fig. 1A. To allow for Doppler frequency shift, 40 channels of weighting resistors are provided each detecting echos shifted by increments of 10 c/s. Output, from a specific threshold device indicates a target with a corresponding velocity. (F) Fig. 7. The various frequencies are separated out by filters 109/117, having bandwidths wide enough to accommodate any Doppler shifts and the filter outputs connected to a tapped delay line 105 via a " random " matrix corresponding to that used in transmission. (G) Fig. 8. To separate out Doppler frequency shifts with a resolution of 10 c/s., the nine contiguous filters of Fig. 7 are sub-divided into 112 overlapping filters 118, each 90 c/s. wide and having centre frequencies spaced by 10 c/s. Filters having pass bands 295/385 c/s., 385/475 c/s., 475/565 c/s. . . 1015/1105 c/s., i.e. the filters occupying the corresponding lowest parts of the nine pass bands of Fig. 7 (suitably heterodyned down), are connected to a first random matrix and delay line assembly. Successive sets of nine filters are similarly connected to matrixes and delay lines, whereby forty outputs are available corresponding to forty target speeds. (H) Fig. 9. The transmitted pulse, heterodyned down in mixer 127 is sampled in gates 128 by 1 Ás pulses at intervals of 333 Ás from generator 129. Each sample passes through a 332 Ás delay 120 to arrive back at the delay input via gates 123, 124 immediately before the next sample. The samples are successively combined at the input of the delay, whereby when the transmitted 100 ms pulse has finished, there are 300 samples circulating in the loop 120-123-124 at the rate of once. per 332 Ás and representing a compressed version of the transmitted pulse. The thus repeated compressed pulse is fed to a correlating bank described below. The received echo pulse is heterodyned down at 103 and is passed to 40 sampling/ delay/loop channels 130/131/132/133 similar to that described for the transmitted pulse, whereby circulating repeated compressed versions of the echo pulse are produced. The sampling rate varies about a mean of 3000 kc./s. from the 40 channels to allow for 40 different Doppler shifts. The compressed echos are multiplied with the compressed transmitted pulse in multipliers 134 and the product integrated at 135, to analogue a correlation function, whereby the output of one of integrators rises to a maximum at the time that one of the repeated compressed transmitted pulses coincides with the compressed echo pulse, the channel of said one integrator indicating the Doppler shift of the echo pulse.

As shown, a semi-conductor 21 is mounted on a jig, (not shown), and is scanned by a flying spot scanner 31, mounted in an inspection module supported by an arm of a lead-wire cutting and attaching mechanism, (not shown), through a lens 33. Part of the light reflected from the semiconductor 21 is fed through an objective lens 34 and a fibre-optic tube 35 to a multiplier photo-tube 32. Part of the view of the scanner 31 is fed via a mirror 38 and lens 39 through a reference standard, comprising a photographic transparency, to a multiplier photo-tube 41. The output signals from the photo-tubes 32, 41 are compared in an analyzer unit 44 producing quadrature and rotational error signals x, y which are fed to a servo unit 45 producing a mechanical movement aligning the lead-mechanism with the semi-conductor device. The signals from the multiplier photo-tubes 32, 41 are alternatively fed, through a switch 50, to a viewing monitor tube 49. The size of the raster on scanner 31 is adjusted by a zoom control 165 whereby the scanned area of the semi-conductor device is reduced as the misalignment decreases.

1,017,470. Pleating fabrics. H. NATHANSON. Nov. 24,1964 [March 26,1964], No. 47661/64. Heading D1S. Apparatus for forming pleats in a sheet 31 of drapery material comprises (a) a base member 11 having a plurality of spaced pleating stations A, A, B, B, . . ., each station having a plurality of fixed crease-forming elements or tines T1, T2, T3, T4 defining channels and a plurality of movable crease-forming elements or fingers F1 F2, F3, one for each respective channel; (b) reciprocating means to move the fingers F1, F2, F3 into the channels in ordered relation beginning with an interior finger location and progressing successively outward in opposite directions from the interior location, element by element and station by station, until a sheet 31 interposed between the tines T1, T2, T3, T4 and the fingers F1 F2, F3 is impressed with creases at at least a plurality of the stations; and (c) stapler fastening means 17 mounted to reciprocate at each station A, A, B, B,... to secure the creases to form a pleat at each station. Horizontally spaced rollers 19 are mounted on a frame 13 which is movable vertically by a pneumatic unit 25 through rods 23 and a rack and pinion 24. The means 17 comprises horizontally spaced stapler guns mounted on a frame 15 movable vertically by a pneumatic unit 29 through a support 27. At each pleating station, the tines T2, T3 extend above the tines T1, T4 and all of the tines T1, T2, T3, T4 have a recess 35 into each of which a stapler gun 17 may be positioned. The fingers F1, F2, F3 are normally held in their upper positions by tension springs 37 and each is pivotally mounted on a bracket 39 on a carriage 41 horizontally movable on rollers 43. The bracket 39 is connected by a link 45 to a plate 47 horizontally movable by a pneumatic unit 49 through arms 51, the plate 47 being guided by rollers 53 riding on a track 55. A horizontally reciprocable cam 59 driven by a piston 61 of a pneumatic unit 63 acts on a cam follower 57 to force each finger F1, F2 or F3 down. The unit 63 is horizontally movable on rollers 65 and is connected by a link 67 to the plate 47. In use, the sheet 31 is placed so that the end or near end thereof to be pleated rests on the rollers 19 and aligning rollers 69, 73 are lowered to hold the sheet yieldably against rollers 71, 75 so that it can slide easily therebetween. The plate 47 moves forward to the position shown in full lines in Fig. 2 and then the frame 13 is raised so that the rollers 19 lift the sheet 31. The innermost fingers F1 in the stations A, A are lowered simultaneously or in succession to form crease No. 1 and then the fingers F2 followed by fingers F3 of the stations A, A are lowered to form creases Nos. 2, 3, respectively. Similarly, pleats are formed at the stations B, B. If an odd number of pleating stations are provided the last pleat is formed separately. After pleating, the fingers F1, F2, F3 are simultaneously withdrawn and are lifted by the springs 37. The stapler guns 17 move into the recesses 35 and are activated simultaneously to staple the creases formed over the tines T2, T3, Fig. 6. The guns 17 are withdrawn, the rollers 69, 73 are raised, the rollers 19 are lowered and the sheet 31 is withdrawn.

1510550 Microtomes LKB-PRODUKTER AB 25 Nov 1975 [26 Nov 1974] 48465/75 Heading G2J [Also in Divisions F1 F2 and H2] A linear actuator in a microtome for effecting stepwise displacements of a driven object includes an elongate member I which can be caused reversibly to expand and contract in length by the action of an activating device 5, and two releasable clamps 2, 3, in each of which the elongate member 1 may be held stationary in a V-shaped groove 11, Fig. 2. Each clamp may be comprised of a contact screw 13 carried by a spring arm 12 which may be lifted by means of a lever 15 on a fulcrum 16, impelled by an electromagnet having a coil 18 and core 17. A mechanical link 6 may convey the displacements to a driven object (not shown). A sequencing switch 7 is provided, for connecting a power supply 8 to the clamps 2, 3, and the activating device 5, in such a manner that unidirectional stepwise displacements are produced. For example, with clamp 3 released and clamp 2 secured, the activating device 5 may produce an expansion of member 1, causing link 6 to be driven in a leftward direction as shown in Fig. 1, and then clamp 3 is secured, clamp 2 is released, and the activating device 5 then causes contraction, until clamp 2 again becomes secured, clamp 3 is released, and the foregoing cycle is repeated. The switch may alternatively be set to provide displacements in an opposite direction. In one embodiment the member 1, or a portion of that member, is composed of a magnetostrictive material. In another embodiment, a material susceptible to a Piezoelectric effect is employed. In a third embodiment, the member may include a material which expands or contracts when heated, and the activating device 5 is a heater.
