461,259. Lenses. KODAK, Ltd. Aug. 13, 1935, No. 22792. Convention date, Aug. 18, 1934. [Class 97 (i)] [Also in Group XXXVIII] An optical system for use in sound recording or reproducing apparatus comprises a single lens for forming a reduced image of the light source on a film, the lens having a short focal length and having the face thereof which is the nearer to the source aspherically curved about axes at right-angles to the length of the film, so as to correct for spherical aberration. As shown, a short-focus lens 11, which images an elongated light source 10 on a film 12, is preferably made together with a block 17 from a single piece of glass, and has a front aspherical cylindrical surface 15 and a rear plane surface 16. The surface 15 is almost a parabola. Glass of low dispersion is used, to reduce chromatic aberration. Means such as a slotted diaphragm 13 are provided, to limit the length of the image. In the arrangement shown, the lens employed makes possible a very short over-all distance from the filament 10 to the film 12, and the lens may have a working aperture of F 1À0, with freedom from spherical aberration and a magnification ratio of twenty to one. Instead of the lamp filament 10, a slit illuminated through a condensing system may be provided. The proper curvature of the lens 11 is determined in accordance with a given formula.

Striking plates and staples for locks and latches.-A spring plate is mounted in the crack between the door and door-jam, to prevent the insertion of a gimlet or like tool from the outside of the door, into the crack to force back the latch-bolt. The plate 17, may be made of springy metal, or may be spring-controlled and is mounted adjacent to the lug L of the striking plate 15 which enters the crack 12 across which it extends to engage the edge of the door 10 when the door is closed. The edge 20 of the plate 17 is sharp so that it makes a close contact with the door-edge. A gimlet or like tool inserted through the material of the door-jam 11 to enter the crack 12, is deflected by the plate 17 and cannot force back the latch-bolt 14 of the lock 13. The plate 17 may be mounted on the lug L of the striking-plate as shown in Fig. 1, or between it and the door-jam and may be bent so as to allow the lug L to be fitted flush with the door-jam. The plate 17 may be fitted to the edge of the door and may be secured by screws passing through one elongated slot 18 or a pair of elongated slots 21, to allow of vertical adjustability, or it may be secured by two plain screw holes 22.

359,981. Television. BAIRD, J. L. and TELEVISION, Ltd., 133, Long Acre, London. July 30. 1930, No. 23010. [Class 40 (iii).] For colour television in a system employing a receiver constituted by a bank of lamps of the type described in Specifications 222,604 and 291,121, [both in Class 40 (iii), Telegraphs, Electric], each single lamp is replaced by a set of filament lamps each of which emits light of a different colour. Transmitter. Light from a source 14 passes through apertures arranged in three contiguous spirals 11, 12, 13 on a disc 10, and is reflected from the object 15 to light-sensitive cells 16 arranged in a bank. The spirals 11, 12, 13 are covered with strips 17, 18, 19 of translucent material of different colours, e.g. red, green and blue, so that the object is successively scanned by beams of these colours. Receiver. The receiving screen is formed by sets of three lamps 24, 25, 26, each set being arranged in a cubicle formed by intersecting opaque partitions 22, 23. Corresponding lamps of the sets have their bulbs of glass of the same colour, and each set has bulbs of the three colours according to those employed at the transmitter. Each lamp of the set may be enclosed in a cubicle, and a translucent diffusing screen 27 is placed in front of the lamp bank. The signals from a receiving amplifier 37 are distributed to the appropriate lamps as illustrated diagrammatically in Fig. 3, by the cooperation of a switch arm 32 moving over segments 31 with an auxiliary selector switch 36 rotated over segments 33, 34, 35. Each segment 31 is connected to terminals of a set 30 of the lamps, whilst the segments 33, 34, 35 are individually connected to all lamps appropriate to a particular colour. The arm 32 is rotated three times as rapidly as the arm 36, and during each rotation effects the illumination of all the lamps of one of the three colours. In an alternative method, the arm 36 makes one revolution whilst the arm 32 contacts with a segment 31. In this case the lamps of each set are illuminated in succession, and the sets of lamps are successively actuated. The switching devices employed may be of the type illustrated in Figs. 1 and 2 of Specification 347,741. Synchronism and phase adjustment of the receiving system may be effected by the means described in Specifications 320,639 or 336,655, [both in Class 40 (iii), Telegraphs, Electric]. The signals may be sent over a number of separate channels and applied simultaneously to the lamps of a set, the selector device 33 .. 36 being unnecessary in this case. At the transmitting station the object may be Bood-lighted and explored in the manner described in Specification 283,957, [Class 40 (iii), Telegraphs, Electric]. Specifications 347,254 and 348,211 are also referred to.

533,310. Two-part couplings. ROTAX, Ltd., and ALLEN, A. MASSEY-. Aug. 10, 1939, Nos. 23088 and 27659. [Class 38 (i)] The contacts h of multiple plug and socket couplings, terminal pillars &c. are located in holes s in a body a and locked therein by a plate j having holes r displaced from the holes s so that the edges of the holes r engage grooves q or reduced portions of the contacts The holes r, s may be displaced in the same direction so that the locking engagement is effected by a lateral rotary movement of the plate j relative to the body g or the displacement may be in various directions so that assembly is effected by first engaging the contacts with the plate j and then inserting them in the holes in the body g. This operation can be facilitated by a jig consisting of a set of flexible pins mounted in a base, the pins being inserted through the holes in the body g into the contacts which are previously inserted in the plate j. Another form of jig for use with contacts arranged in straight lines consists of plates v, Fig. 10, notched at x. to hold the contacts and mounted to turn on pivots in a support w. The jig being inserted between the contacts with the plates v at right angles to the position shown, when the plates are turned they move the contacts into position for insertion in the body g.

427,471. Controlling variable-speed gearing. REO MOTOR CAR CO., 1331, South Washington Avenue, Lansing, Michigan, U.S.A. Aug. 18, 1933, No. 23115. Convention date, Dec. 27, 1932. [Class 80 (ii)] Relates to means for operating from a handle T, Fig. 11, mounted on the cowl S of a vehicle a two-speed and reversing gear such as is shown in Fig. 1, which is used in series with automatically-changing gearing such as that described in Specification 427,470, so that each forward-speed setting of the handle will result in a drive which is variable automatically within limits. To change from the neutral position of Fig. 1, C being the driving-shaft, to the high-speed position of Fig. 1A, a gear H and a gear cluster E must both be moved left, so that both forks I, F, Fig. 2, must be operated. To change from neutral, Fig. 1, to the low-speed position of Fig. 1B, the cluster E alone, and therefore the fork F alone must be moved. To change from neutral, Fig. 1, to reverse, Fig. 1C, again both forks I, F, Fig. 2, must be moved, but right of Fig. 1 instead of left. The forks I, F are connected to sliding racks L<1>, K<1> engaged by toothed sectors M<2>, M<1>. The sector M<2> is loose on the end of a rock-shaft M with which the sector M<1> is integral. The loose sector M<2>, shown also in Fig. 15, is locked to the sector M<1> by a ball 0 except for one movement. The ball 0 is carried in a long notch O<2>, Fig. 14, in the sector M<2> and is normally held in engagement with a notch O<1> in the sector M<1> by a cylindrical envelope P, Fig. 16. A slot P<1> on the inner surface of the envelope P is right over the ball O in the neutral position shown in Fig. 6. The rock-shaft M is adapted to slide, and for forward speeds is in the position of Fig. 2 and is held there by a spring U and a lock plate V. Each change is effected from the neutral position of Fig. 6. Change to the high-speed position of Fig. 4 is effected by rocking the shaft M clockwise when a shoulder P<5>, Fig. 14, engages a shoulder P<6> so that the segment M<2> must move with the segment M<1>, and both forks are operated. The ball O locks the segments together on return to neutral. Change to low speed is effected by rocking the shaft M anticlockwise. A shoulder M', Fig. 6, on the segment M<2> is immediately stopped by a lug P<2>, Fig. 16, on the envelope P and, as the segment M<1> begins to turn, it thrusts the ball away out of the notch O<1>, Fig. 15, so that the ball rides up into the notch P<1>, Fig. 6, and leaves the segment M<1> free to turn alone anticlockwise moving the fork F only and bringing the cluster E from the position of Fig. 1 to that of Fig. 1B. This rocking of the shaft M has been effected by axial sliding of a rack bar Q <1>, Fig. 2, which engages a quadrant Q fast on the shaft M and is connected by a flexible shaft R, Fig. 11, to the handle T which is thus moved axially to change between high and low forwards speeds each of which is varied automatically by the auxiliary gearing. To bring in reverse, the handle T is brought to middle position with the sectors in neutral, Fig. 6. The handle T is now turned so that the rack bar Q<1> is turned so as to slide the shaft M right of Fig. 2, a notched flange V<2> then passing over to the other side of the lock plate V to the position of Fig. 10, stressing the spring U. The teeth of the sector M<2> now engage both racks L<1>, K<1> so that when the handle T is again moved axially these racks and both forks must move together, as is necessary to change from the neutral of Fig. 1 to the reverse of Fig. 1C.

616,889. Thermionic valves. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 2, 1946, .No. 23142. Convention date, Oct. 30, 1941. [Class 39 (i)] [Also in Group XL (c)] An ultra-short-wave oscillator comprises a valve with pairs of lead-ins connected to the cathode, anode and grid electrodes, the lead-ins being arranged symmetrically around the centre of the valve and forming part of a fourconductor transmission line which is tuned by four other conductors sliding inside them and connected together by a common rigid spacer member, the capacitance and inductance per unit length of the lead-ins and transmission line being made substantially equal. Fig. 3 shows the conductors 28, 29, 30 and 31 of a transmission line connected to the lead-ins of the valve 41 and tuned by the members 32, 33, 34 and 35 connected to the common insulated spacer 36 adjusted by screw 54. Fig. 8 shows schematically the connections to the valve electrodes, the cathode being balanced with respect to earth by inductor 58 and capacitor 59. The positive H.T. supply is connected to the valve anode at the voltage node point 60 and the grid leak 61 is connected to the grid at voltage node point 62. The valve is designed to use a conventional octal base. Figs. 4, 5 show how the symmetry of the electrode connections is obtained by mounting them in a plane parallel to the base of the valve. The electrodes are spaced apart and supported by two end mica plates 66, 67 held in place by turned-over lugs 68 on the anode, the electrodes being connected by short metal straps to the corresponding valve pins. The constants per unit length of the transmission line and the valve lead-ins are made substantially equal by maintaining the same spacing between the four parts of the transmission line and the four lead-ins connected to the grid and anode electrodes, Fig. 6 (not shown).

Improvements in or relating to the manufacture of titanium
|
en
|
Titanium of low hydrogen content is obtained by reacting titanium tetrachloride with sodium in an inert (e.g. argon) atmosphere and in the presence of lower chlorides of titanium and leaching the products with an aqueous solution of a mineral acid containing a soluble phosphite, preferably an alkali metal phosphite. The presence of the lower (or sub-) chlorides is ensured by using an excess of the tetrachloride amounting to more than 0.25 per cent and preferably from 0.5 to 3.0 per cent by weight of the stoichiometric quantity. The acid solution should contain less than 10 per cent sodium phosphite, preferably between 0.5 and 2 per cent by weight; a preferred solution contains 2 per cent hydrogen chloride and 1 per cent sodium phosphite. In an example molten sodium was reacted at 850 DEG C. in argon with 0.8 per cent excess titanium tetrachloride, cooled in the argon, ground to powder, and leached twice at room temperature with the above preferred solution. The hydrogen content of the titanium was 0.003 per cent. Specification 788,308 is referred to.

1,194,480. Transistor amplifier circuits; generating electrical oscillations. TEKTRONIX Inc. 16 May, 1968 [24 May, 1967], No. 23212/68. Headings H3B and H3T. [Also in Division G1] Amplifier circuit.-In a linear direct current amplifier the input is applied between the bases of two transistors 54, 56 whose emitters are connected together through a gain control resistor 58 and whose collectors are connected to the emitter and base, respectively, of a transistor 60. Positive voltages appearing at the collector of transistor 60 are then amplified by a double emitter follower circuit comprising transistors 62 and 72 and negative voltages by a similar circuit comprising transistors 64, 78. The output terminal 80 is connected through resistance 82, inductance 84 and thermal stabilizing resistances 74, 76 to the emitters of transistors 72, 78. The resistance 82 provides a z 0 termination for a coaxial line connectible to terminal 80, and inductance 84 provides additional output drive at low frequencies. An R.C. network 86, 87 compensates for the inductive effects of transistors 72, 78. Transistors 62, 64 are connected to their respective power supplies through current source transistors 68, 70. To prevent a surge of current in a winding 26<SP>1</SP> when a switch contact 83 is moved from a terminal 98 to its normal position on amplifier output terminal 80, a capacitor 146 is charged whilst contact 83 is on terminal 98 to establish heavy conduction through transistor 66 and diode 154. On return of contact 83 to terminal 80 this transistor continues to conduct until the capacitor has discharged, and during this time holds the bases of transistors 62, 64 to earth potential. Oscillator circuit.-To produce a decaying oscillation 139 a capacitor 138 is first charged and then connected to an oscillator circuit to provide the latter with a decaying supply voltage. The oscillator circuit comprises crosscoupled transistors 104, 106 and a tuned circuit formed by capacitor 102 and a winding 26<SP>1</SP> on a magnetic core 12<SP>1</SP>. The embodiment described provides oscillations of 10-15 kHz, decaying in about 0À1 seconds, for demagnetizing the core 12<SP>1</SP>.

322,162. Hertig, E. Aug. 13, 1928. Cleaning.-Clinker is removed from the heating surfaces of boilers &c. by the flame from a burner nozzle 14 which is supplied with oxygen and oil fuel by pipes 11, 12 and is surrounded by a sleeve 15 lined with refractory material. The fuel mixture is ignited initially by the flame from an asbestos wick saturated with naphtha, inserted in the annular space between the burner nozzle and the refractory lining. The refractory lining serves to radiate heat to the burner nozzle to heat the fuel mixture before discharge. The fuel reservoir 6 is fitted with a hand pump 8 and is also connected to the oxygen supply pipe by a valve-controlled pipe 10 so that the pressure of the oxygen can be utilized for forcing the fuel to the burner nozzle. In another form of burner the fuel is heated by passage through a tube coiled around the burner head before mixing with the oxygen.

Shutters for photographic cameras

884,180. Photographic shutters. NEUBERT, W. July 7, 1959 [July 17, 1958], No. 23282/59. Class 98(1). A shutter for photographic cameras comprising shutter blades which perform an oscillatory motion for opening and shutting the camera aperture is characterized in that the first half oscillation is produced by forces engendered in springs which act on the element provided for actuating the blades, said forces exceeding in magnitude the spring forces which induce the second half oscillation, and the energy of motion of the blades performing the first half oscillation being used in known manner to energize springs for driving the blades during the other half oscillation, and that the greater power applied to the performance of the first half oscillation is at least partly supplied by an energy storage spring energized by the action of setting or cocking the shutter. As shown, shutter blades 9 pivoted about fixed points 21 are controlled by an actuating ring 8, which-in the rest position shown in Fig. 2-is urged clockwise m the shutter opening direction by a strong spring 26 but is prevented from moving by a leaf spring arresting means 28, 31. On cocking of the shutter by rotation in the clockwise direction of a setting lever (not shown) coaxially mounted in the shutter housing, by way of a lever 39 caused to rotate by an abutment of said setting lever, and further by way of a member 42 pivoted on a lockable arm 41 of said lever 39, an energy storage spring 43 engageable with an abutment 44 of the ring 8 is tensioned. At the same time a lever 46 is moved to the "ready" position shown in Fig. 2 by a second abutment 45 on the setting lever. When the shutter is released, the setting lever is spring moved in the direction of arrow 38, abutment 45 moves lever 46 in the direction of arrow 46a, and abutment face 47 thereon deflects leaf spring 31 of the arresting means 31, 28 out of locking engagement with leaf spring 28, which is then deflected by the sloping portion of an abutment 34 on the ring 8 to allow this ring to rotate in the clockwise direction for opening of the shutter blades 9 under the combined tension of springs 26 and 43. When the blades 9 reach their wide open position, a further abutment on the setting lever engages a pin 59 on locking lever 40 and displaces this lever against spring bias for releasing-underloading of a weak spring 60- the arm 41 and hence also the spring 43. At the same time, an abutment 51 on ring 8 comes against a stiff U-shaped spring 50 and the direction of motion of ring 8 is thereby reversed, the ring 8 being driven during the ensuing blade closing motion by now tensioned spring 27, which is stronger than spring 26 alone but not as strong as springs 26 and 43 together. When the blades 9 reach their closed positions the ring 8 is locked by spring 28 engaging abutment 34 and being itself engaged by spring 31, the abutment face 47 now riding on ring 8 (see Fig. 3) out of interference with this latter spring. Exposure regulation. The shutter as described above and as shown in Fig. 2 is set for a minimum time exposure (say 1 /1000th sec.). For exposures of say 1/500th sec. speed setting ring 49 is moved a short distance to the right, whereupon lever 53 and return spring 50 are spring urged into the positions shown in Fig. 3, and the blade opening motion of ring 8 is reversed by means of spring 27 along. A second leaf spring arresting means 35, 36 co-operating with abutment 37 is provided for arresting the blades in the open position, but is normally held inoperative by the engagement of spring 36 by a finger of a lever 63. For exposure of say 1/250th sec. however, this second arresting means is made operative by moving the setting ring 49 further to the right, into the position shown in Fig. 3, the blades 9 then being arrested in their wide opening positions until an abutment 64 on the setting lever (which may be coupled to a retarding mechanism) engages upturned face 56 of a lever 57, the said finger of lever 63 then displacing spring 36 for releasing the arresting means 35, 36. For exposures of say 1/125th sec. speed setting ring 49 is moved even further to the right so that lever 57 moves into its alternative position (shown in dotted lines in Fig. 3), the blades 9 then being arrested in their open positions until abutment 64 engages upturned face 55 on lever 63. In alternative embodiments (Figs. 5-8, not shown) the second arresting means 35 and 36, and levers 63, 57, are dispensed with and exposure time regulation is by various arrangements of spring devices which are placed in the path of abutment 51 for reversing the direction of motion of ring 8, and which are adjustable in position or strength by the speed setting ring 49. In a further embodiment (Fig. 1, not shown), the two arresting means are in the form of spring urged locking pawls 10 and 16 and the energy storage spring 3 acts indirectly on the actuating ring through a further pawl 6. The springs 26, 27, and 50 may be arranged in symmetrical multiples, and the actuating ring 8 may be mounted on roller bearings to reduce friction (Figs. 9 and 10, not shown). In further modifications the shutter may be used in cine cameras if the tensioning of spring 43 and release of arresting means 28, 31 is effected by motor means.

999,856. Electromagnetic relays. GENERAL ELECTRIC CO. June 19, 1962 [July 3, 1961], No. 23499/62. Heading H2B. In a relay comprising a housing, an axially movable metallic sleeve 55, an armature 57 slidable on said sleeve and arranged to move it between two positions, a cap 65 secured around said sleeve and a spring 69 mounted between the armature and cap, the sleeve is split axially to reduce eddy currents. The sleeve is preferably of brass and carries a contact bridge 59 at one end which co-operates with fixed contacts 77. The operating characteristics of the relay are set during manufacture by suitably positioning the cap on the sleeve where it is held by the resilience of the sleeve. The housing comprises three interfitting parts 5, 7, 9 which are held together by means of a pin 13 which passes through them and a spring fastener 21. The housing has a plurality of projections 107, 109 which co-operate with slots 103, 105 in a mounting frame 95 so that the relay may be mounted in many orientations. When the relay is energized armature 57 moves upwards, compressing spring 69, thereby urging sleeve 55 and contact bridge 59 upwards. On de-energization, the armature strikes the contact bridge a hammer-blow and so breaks any weld which may have been formed.

Improved method of preserving foodstuffs for animals
|
en
|
A pig, cattle or poultry feed consisting partly or wholly of fish, e.g. finely divided herring, is preserved, without development of objectionable odour or taste, by the addition of a culture of lactic acid-producing bacteria which have grown in a liquid medium of pH4 or less and are capable of proliferating in the feed to produce pH4 or less therein. Desirably, the feed should contain a nutrient such as molasses for the bacteria. The preferred culture is of Lactobacillus plantarum. A dry animal food such as rye bran, wheat bran, dry sugar beet slices or dried potato peelings may be incorporated to facilitate storage and transport of the product.

1503713 Fusible cut-outs McGRAWEDISON CO 30 May 1975 [28 June 1974] 23662/75 Heading H2G An electric fuse 10 comprises a high thermal conductivity ceramic housing 12 with an elongate passage 18 therein containing a constricted (at 40) fusible element 20 of silver, copper or other high melting point metal and a sand filler 45, the fusible element being fusible by a sudden heavy overload or by a sustained low overload. On passage of the rated current, the constriction 40 is heated nearly to its melting point, excess heat being carried away via the sand filler, the ceramic housing and a cooling medium, which may be blown air, surrounding the housing. The constriction is positioned closer to the inner surface of the housing than to the end cap 44 aiding removal of most of the heat through the body of the fuse and preventing a rise in temperature at the terminals sufficient to melt the soldered connections of the fusible element with the cap 44 or of the cap with the terminal lug 56. Fuses may have three passages in the housing with fusible elements inserted in one, two or all three passages as required giving three different current rating fuses from a common set of components. Two or three such three-passage housings may also be bound in parallel by suitably shaped end caps for further ranges of current rating. The fusible element may have a number of constrictions along its length each of which may blow thus reducing the possibility of arcing subsequent to a heavy overload.

619,145. Attachments for screwing; die-heads. HOGFORS, H. F. B., and LARSSON, E. V. U. Aug. 9, 1946, No. 23707. Convention date, Aug. 20, 1945. [Class 83 (iii)] A screw-threading attachment for a lathe has a die or tap holder 8 rotatably and slidably mounted on a support 1 fitted to the tailstock of a lathe, an adjustable rod 6 disposed to prevent the holder from rotating while permitting the latter to move longitudinally to effect the screw-thread cutting over a length determined by the setting of the rod, and a rod 14 movable into and out of an operative position in which it secures the holder against rotation and permits retraction of the die or tap. The work is rotated by the headstock spindle and the die is brought into contact with the work by movement of the tailstock. During the cutting operation, an arm 9 attached to the holder bears against the rod 6 which extends beyond a flange 2 fixed to the support by an amount equal to the desired length of thread. This arm traverses the rod 6 and on reaching the end of the latter, stops the cut by allowing the holder to rotate. To unscrew the die, the rotation of the headstock is reversed, and the rod 14 pushed forward until its head 15 contacts a stop 16 on the rod 6. The rod 14 now arrests the arm 9 so that the work is unscrewed from the die. To ensure that the rod 14 is returned to its inoperative position, a plate 17 frictionally pivoted on the arm 9 is provided. During the cut, this plate occupies the position shown in Fig. 2, so that it overlaps the end of the rod 14 during the unscrewing operation. The holder 8 is provided with an adaptor (not shown) for tapping.

501,369. Purifying and de-waxing oils. STEVENS, A. H. (Standard Oil Co. (Ohio)) Aug. 31, 1937, No. 23799. [Class 91] A process for de-waxing oils consists in treating the oil below 5‹ F. with a solvent composed of 10 to 15 per cent by volume of sulphur dioxide and 90 to 85 per cent of isopropyl ether, and then removing the separated wax. The oil may first be freed from non- paraffinic components by extraction with the same mixture of solvents containing a larger amount of sulphur dioxide. In examples: (1) a wax-containing oil is mixed with 3 volumes of a mixture of 15 per cent sulphur dioxide and 85 per cent isopropyl ether, and the mixture is chilled to 4‹ F. The wax is removed in a filter press, and the filtrate freed from solvent by distillation; (2) a lubricating oil is mixed with 3 volumes of a mixture of 75 per cent sulphur dioxide and 25 per cent isopropyl ether at 60 to 110‹ F. After separation, the raffinate layer is treated with 3 volumes of the solvent mixture used in example 1, and chilled to 4‹ F. The wax is removed by a filter press, and the dewaxed oil is freed from solvent. Specification 441,705 is referred to.

870,059. Digital electric calculating apparatus. OWEN, C. E. July 25, 1958 [July 27, 1957], No. 24028/57. Class 106 (1). An electronic multiplying device 1 in which successive multiplier digits cause repeated additions of the multiplicand to a result register together with appropriate denominational shifts, the shifts being counted by a counter 4, is augmented by a source 6 of three predetermined numbers and a group of gates 7 controlled by the counter, to form a sterling to pence converter. The sterling amount, ú12: 13: 11, as shown, is entered into the multiplier register; the first two digits, both ones, are multiplied by 1000 which is entered into the multiplicand register from source 6 via gates 7 under control of the counter (this results in 11000 being in the result register); the second two digits 3 and 1 are multiplied by 120 which is entered into the multiplicand register from source 6 as before (this causes the addition of 13 x 120 x 100 to the result register since the basic multiplier is designed to give a cumulative digit shift for each digit of the multiplier used giving 157100); and the remaining digits, 2 and 1, are multiplied by 24 which is entered into the multiplicand register (this causes the addition of 12 Î 24 x 10000 to the result register) giving 3047000 which is 1000 times the number of pence in ú12: 13: 11. A similar arrangement for converting from pence to sterling using a dividing device is described. Conversions from other mixed bases are possible, it is stated, by appropriately modifying the factors used.

1353449 Photographic camera indicating devices SEIKO KOKI KK 23 May 1972 [31 May 1971] 24146/72 Heading G2A A photographic camera has an indicating device, e. g. a lamp L, a light emitting diode or a liquid crystal, which operates in a steady manner, e.g. continuous light emission, when the light incident upon a photoconductor Rc is above a predetermined maximum strength, and which operates a varying manner, e. g. periodic light output, when the light incident upon the photoconductor is less than a predetermined minimum strength. In the former event over exposure is likely and in the latter camera vibration is likely. Contact slides a 1 , b 1 of changeover switches S 2 A, S 2 B are both ganged for movement with the shutter release. In the first position the contact slides contact a 3 , b 3 respectively. If light incident on Rc is such that V > V o , strong lighting condition, then transistors T 1 , T 2 and T 3 all conduct to cause steady illumination of the lamp L. If the light incident is below the predetermined maximum strength determined by resistor R 1 so that V x <V o then the transistors are non conducting and the lamp L is not lit. Further movement of the shutter release causes the contact slides to contact a 4 , b 4 . In this condition transistors T 3 , T 4 together with resistors R 7 , R 8 and capacitors C 1 , C 2 constitute an astable multi-vibrator. If the light incident is below the predetermined minimum strength determined by resistor R 2 so that V x <V o , transistors T 1 and T 2 are cut off, but transistor T 3 conducts, base current flowing through the lamp L, slide switch S 2 B and capacitor C 1 . Thereafter the circuit of transistors T 3 , T 4 causes periodic illumination of the lamp L. If the incident illumination is above the predetermined minimum strength so that V x >V o , transistors T 1 , T 2 and T 3 continuously conduct and transistor T 4 is permanently cut off the lamp L remaining unlit. In a further embodiment, Fig. 2 (not shown) changeover switch S 2 A has a further contact so that further depression of the shutter release connects photoconductor Rc in series with a shutter timing capacitor the common point being connected to a Schmidt trigger which controls the closing action of the camera shutter.

The foil 1 is drawn from a web by means of an electromagnetic gripper 3 and is clamped in the right-hand groove 17 by the bar 21 whilst the gripper returns to its initial position. The frame 29 is then raised pneumatically and clamped electromagnetically to the housing 15, clamping the remainder of the foil periphery in the grooves 17 and severing the foil from the web by means of a blade 31. A contact heater plate 36 is then lowered into engagement with the foil, the housing 15 being evacuated through a pipe 33 to facilitate engagement. When the foil is soft, the heater plate 36 and the foil are raised, a table 44 carrying a box 40 to be covered is raised so that the upper edges of the box contact the foil, compressed air is forced through the pipe 33 forcing the foil on to the box and its contents, and the frame 29 and bar 21 are released. The foil may be stretched over the housing 15 by engaging it with the gripper 3 as this returns to its initial position.

769,454. Liquid-liquid extraction process. GROLL, H. P. A. Aug. 23, 1954 [Aug. 24, 1953], No. 24446/54. Class 81(1) Oils and other soluble mixtures of organic substances are fractionated by liquid-liquid extraction under such conditions of temperature and pressure that the solvent power of the selected solvent is reduced by increase of temperature, the material to be fractionated being extracted selectively with a solvent whose solvent power has been adjusted by control of temperature and pressure and the extracted part of the oil being precipitated from the solvent by increasing the temperature of the extract, the process being characterized by increasing the hydraulic pressure of the extract before carrying out its precipitation by increase of temperature. The process is applicable to the fractionation of crude oil residues, tar oils, synthetic hydrocarbons, hydrogenation products,. glycerides, tall oil, mixtures of fatty acids and resinous acids and mixtures such as boiled linseed oil, tandoils, voltolized oil and liquid alkds. Specified solvents include ethane, propane, butane, petroleum ether and hydrocarbon mixtures, dichloromethane, dichlorodiffuoro-methane and carbon dioxide. As shown oil is pumped from tank 1 via heater 3 into the middle of column 4 operated at a temperature T1 such that the greater part is extracted leaving a heavy residue. This residue Fl is withdrawn through valve 5. Solvent passes through valve 6 and rises up the column, the extract leaving through line 7. It is pumped to a heater 9 and separator 10, the required increase in pressure being by throttling valve 23 while running pump 8 at a constant rate, or by adjusting the rate of pumping while keeping the valve position constant. Precipitation takes place in separator 10, part of the precipitate being returned to column 4 through cooler 11. The other part passes through line 13 to cooler 15 where its temperature is adjusted to the operating temperature T2 of column 16. It is then fractionated in column 16 into two parts, a bottom fraction F2 being withdrawn and top fraction F3 separated from the extract. The solvent from separator 10a is returned via cooler 21a and valve 6 to column 4. Solvent for starting the process is taken from tank 17 via pump 18, line 19 and heater 20 (which heats it to the temperature T2 of column 16) and then to column 16. The oil for column 4 may be pre-diluted with solvent before it is heated in heater 3. Solvent withdrawn with th separated fractions may be recovered and returned to the process. In this process, T1<T2, and the first heavy fraction F1 is not further, separated. The method of operation is also described in which the first heavy fraction is further separated, the temperature of column 4 in this case being greater than that of column 16.

The Specification refers to sulphur-containing hydroxy acid of formula: HO-R2-S-R10-COOH where R2 is an alkylene group containing 2-20 carbon atoms and R10 is an alkylene group containing 1-10 carbon atoms, and to the lactones of these hydroxy acids. In Example (4) Hydroxylpropylmercaptopropionic lactone was prepared by heating gamma-mercapto propanol with acrylic acid in the presence of hydroquinone; (5) Hydroxyhexylmercaptopropionic acid lactone was similarly prepared from omega-mercapto hexanol; (7) gammahydroxypropylmercaptoacetic acid lactone was prepared by heating mercaptoacetic acid with gamma-chloropropanol in the presence of aqueous sodium hydroxide, extracting the resulting solid with acetone and then suspending it in ethanol and hydrochloric acid to obtain a salt which was washed with alcohol and distilled.ALSO:Polymers for increasing the sensitivity of photographic silver halide emulsions have at least three recurring units of the formula: -R10-COO-R2-S-where R2 is an alkylene group containing 2-20 carbon atoms and R10 is an alkylene group containing 1-20 carbon atoms The polymers may have a molecular weight of 500-10,000 and are made by the auto-condensation of a hydroxyacid of formula: HO-R2-S-R10-COOH or its corresponding lactone. The latter condensation may be effected in the presence of p-toluene sulphonic acid, chloracetic acid or zinc chloride. Examples describe the polymerization of (1)-(3) Hydroxyethylmercaptoacetic acid lactone; (4) Hydroxypropylmercaptopropionic acid lactone; (5) Hydroxyethylmercaptopropionic acid lactone; (6) Hydroxyhexylmercaptopropionic acid lactone; (7) Hydroxypropylmercaptoacetic acid lactone; (8) Hydroxyethylmercaptoacetic acid.

1348923 Multicolour hetero yarns VICKERSZIMMER A G PLANUNG UND BAU VON INDUSTRIEANLAGEN 19 April 1971 [15 April 1970] 24530/71 Heading B5B [Also in Division D1] Blended, multicolour yarns comprising filaments of two or more fibre-forming polymers, preferably polyesters and polyamides, are prepared in a process which comprises melt extruding two or more polymers, one of which is dyed, simultaneously through spinnerets, each of which is associated with a single polymer, to form at least two groups of filaments which are solidified and guided in a single plane so that filaments of different colours alternate and lie next to one another and thereafter joining the groups of filaments into a multifilament yarn which is then wound up by conventional winding means. At least one of fibre-forming polymers may contain a delustrant and/or may exhibit higher thermal shrinkage than the other component polymers, when the multifilament yarns produced by the process combine not only filaments of different colours but also of varying lustre and/or, after suitable heat treatment may be yarns of high-bulk or loop yarns. Between formation of the yarn and wind-up the multifilament may be given a spin-finish, drawn and textured. In apparatus suitable for preparing the multicolour blended yarns two polymer streams are fed from separate tanks 1 and 2 to spinnerets 6 and 7 in spinning beam 5 and extruded as two separate groups 8 and 9 of filaments which are solidified and pass through a guide 10 in which filaments of group 8 alternate with those of group 9 (Fig. 2, not shown). The groups 8 and 9 are combined on roll 11 to form a multifilament and fed to draw rolls 13, 14 via roll 12 which applies a spin finish to the yarn. After drawing the multifilament passes through texturing zone 15 where it is optionally crimped and is then wound up on bobbin 16. Blended yarns of different counts useful in the preparation of fleece-covers, cut-pile carpets and boucle goods may be prepared by using spinnerets in which the orifices have different diameters, the colour effect of the blended yarn being further affected if the orifices have different cross-sectional shapes.

1437942 Change-speed control AUTOMOTIVE PRODUCTS Ltd 25 May 1973 [25 May 1972] 24784/72 Heading F2D In a four speed and reverse automatic transmission (not described) on a motor vehicle, liquid - pressure - engaged ratio - establishing clutches 14, 19 and brakes 21, 64, 65, are controlled by a single automatic shift valve 15, the spool 39 of which is moved stepwise between four axial positions by liquid pressure supplied selectively through two flow paths to ports 71, 79, through an auxiliary valve or valves, e.g. 74, 75, to act on separate end pistons 49, 51 shifting the valve spool as described below. Figs. 6 to 9, not shown, use a single auxiliary valve (211) moved into three positions by speed-responsive pressure supplied by an output-driven pump and opposed by a spring, loaded by the engine accelerator and a manual mechanical override. Figs. 1A, 1B, shown, use two auxiliary valves 74, 75, opened by energizing solenoids through an electronic circuit (not described) responding to output speed and load. Pressure supply and regulation.-A single input-driven pump 10 feeds a main pressure regulator valve 11 which spills to a chamber 107 under the influence of delivery pressure 104 opposed by a spring 109, by pressure from the reverse port 35 of a manual selector valve 23, and by line pressure supplied at 111 by a solenoid valve 76 energized when engine throttle opening exceeds a predetermined value. The spill chamber 107 feeds a spring-loaded secondary regulator valve 101 feeding a torqueconverter 103 and lubrication line 122, and, through a manually or thermostatically controlled valve 127, an oil cooler 126. Manual selector valve 23 has four settings, drive, neutral (shown), reverse and park lock. Operation. Drive. First ratio.-Moving the manual selector 23 one step left supplies pressure from a port 29 to a line 30 which directly feeds the clutch 14, which is a forward clutch, engaged in all forward ratios. Line pressure 30 also passes to inlet ports 57, 58 of the automatic shift valve 15, but is initially blanked there, so that the forward clutch engages alone and provides first ratio for starting. 1-2 Upshift.-Under the appropriate speedload condition the electronic circuit energizes the solenoid valve 74 which feeds line pressure 30 at 77 to the left face of the piston 49 and at 78 to the right face of the opposite piston 51 of the automatic shift valve 15. Both pistons 49, 51 move inwards to shoulders 47, 48, the piston 51 taking along the valve spool 39 one step left in opposition to a spring 56 between the spool and the left piston 49. Line pressure 30 now passes through ports 57, 59 of the shift valve to engage the brake 64 for second ratio. 2-3 Upshift.-The appropriate signal energizes the solenoid valve 75, whilst maintaining 74 energized. Line pressure through 75 and a port 79 is applied to a space between the right piston 51 and the right face of the valve spool 39, shifting the latter a second step left, until stopped by a central stem 54 on the left piston 49, whereupon the second brake 64 is exhausted at 66 and the third brake 65 pressurized at 58, 61. 3-4 Upshift.-The solenoid valve 74 is de-energized leaving 75 energized alone, whereupon the left piston 49 and valve spool 39 are moved together a third step left, exhausting the two brakes 64, 65 and pressurizing the clutch 19, which is used with 14 for fourth ratio. Reverse.-Movement of the manual valve 12 one step right from neutral (shown) to reverse, supplies line pressure 29 past a ball valve 81, through ports 97, 98 of a shift smoothing valve 68 (described below) and the automatic shift valve 15, to the direct-reverse clutch 19 and, closing the valve ball 82 on to a seat 83, to the reverse brake 21 through a restrictor 84, which ensures prior engagement of the clutch 19. On release of reverse brake pressure, the brake 21 exhausts rapidly by lifting the ball valve off its seat, thus by-passing the restrictor 84. Transient pressure control.-During a shift, the automatic shift-valve exhaust ports 71, 66, 67 communicate with exhaust through the shift smoothing valve 68 which is loaded to the left position, shown, by a spring 87 and torqueconverter pressure 124 to permit unrestricted exhaust of an off-going clutch or brake, and rightwards, to restrict the exhaust, by line pressure 30 applied to the left face through a solenoid valve 73 energized during gear shift. In Figs. 5, 5A and 6 to 9, not shown, the two pistons (167, 168) for stepping the automatic shift valve are both at the same end of the spool (137) one on a smaller third piston (169) the other abutting the latter. In Figs. 5, 5A, not shown, the smoothing valve 68 of Fig. 1 is omitted, and pressure for the reverse brake (193) is reduced in relation to that for the directreverse clutch (162) by a reducing valve (189). In Figs. 6 to 9, not shown, the two flow paths for stepping the automatic shift valve are provided by a single four position auxiliary valve (211) the spool of which is moved axially in three steps by speed-responsive pressure from an output driven pump acting directly on one end face in opposition to a spring (224) loaded by the engine throttle control, acting on the opposite end face. A manually operable rod can be moved to act directly on the latter face for forced downshift.

861,303. Feeding sheets. HARRIS-INTERTYPE CORPORATION. Aug. 8, 1957 [Aug. 16, 1956(2)], No. 25018/57. Class 100(1) In apparatus for stream feeding underlapped sheets to a processing machine, the sheets are each registered at the front and side whilst the preceding sheet partially overlies it, and side registration is effected by means which lift the preceding sheet and grasp the sheet to be registered from above and below. As shown in Figs. 2 and 4, sheets in underlapping relationship are fed by tapes 19 over a feed-board 18 up to front stops 20, and are then fed by driven rollers 21 and co-operating drop-rollers 22 to the grippers 17 of a cylinder 15, which may be an impression cylinder, or an auxiliary feed cylinder, in a printing-machine. A lifting finger 24, tapered at the front end, moves transversely inwardly in a slot 14 in the board 18 and beneath a sheet S <SP>1</SP> at a time before the front edge of an underlying sheet S<SP>2</SP> arrives at this point; the finger then moves up to lift the edge of the sheet S<SP>1</SP> and allow the next sheet S<SP>2</SP> to pass beneath the finger. The finger 24 then moves down to grip the sheet S<SP>2</SP>, which is now registered by the front stops 20, against an idler roller 26, after which it moves out to pull the sheet outwardly against a side registration gauge 25. Next, the finger 24 moves out beyond the feed-board 18 and downwardly preparatory to its next inward movement. The finger 24 is transversely slidable in a bracket 28 vertically slidable on a frame portion 27 under the action of a roller 33 bearing on a cam 34 secured to a shaft 35 which rotates once for each printing press cycle. In and out movement of the finger 24 relatively to the feedboard is by a pivoted lever 36, having a roller 38 engaging a groove in a barrel cam 39 fixed on the shaft 35, connected by a link 40 to the finger. The roller 26 is mounted on an arm 29 pivoted to the bracket 28 and urged upwardly by a compression spring 31 against a stop 32 so that the roller remains at the level of the board 18. In the modification shown in Figs. 16 and 18, a gauging finger 133 moves inwardly of the feed-board 18 above a roller 132 and beneath the first sheet S<SP>1</SP>, then downwardly to press the second sheet S<SP>2</SP> against the roller and outwardly to draw that sheet against a side gauge 25, but a sheet-lifting finger 128 first lifts a side edge portion of the first sheet S<SP>1</SP> to the dotted line position, shown in Fig. 18, before the finger 133 moves inwardly. There are two radial fingers 128 on a hub secured to a shaft 126 which rotates through an angle of 180 degrees for each press cycle. The shaft 126 is rotated rapidly to bring a finger 128 up through a slot in the board 18 to lift the edge portion of the first sheet S<SP>1</SP>: this recurs shortly after the feed rollers have gripped the sheet S <SP>1</SP>. The shaft 126 may be rotated by a Geneva mechanism which provides an extended stop period and relatively short periods of acceleration, constant speed, and deceleration.' The finger 133 is integral with a vertical post 134 having a castor 135 adapted to run on a plate 144 which is arranged to be swung up and down by cam means. An L- shaped bar 137 engages in a groove in the post 134 and is extended to accommodate a coil spring 138 which presses the post downwardly. The bar 137 is grooved to receive a fixed guide 1381, and carries a roller 140 which runs in a groove in a barrel cam 142 secured on a shaft 143. Thus both vertical and horizontal movements are imparted to the finger 133. Since the edge of the first sheet S<SP>1</SP> is raised by the finger 128, the finger 133 moves in between the sheets S<SP>1</SP>, S2 without touching either of them. In order to allow more time for registration the cylinder 15, to which the sheets are fed, may be driven at non-uniform speed by an arrangement as described in Specification 743,453, whereby the rear edge of a sheet is moved rapidly over the feed-board 18 by the grippers 17. Specification 676,389 also is referred to.

Method of dehydrating gypsum
|
en
|
In the dehydration of gypsum to the hemihydrate in a sealable indirectly heated vessel, the vessel is alternately sealed for at least three minutes and then vented, until the desired dehydration has occurred. Venting is generally effected at 30 to 40 p.s.i.g. and temperatures at about 300 DEG F.; the vessel is preferably resealed before the temperature drops below 212 DEG F. and the product is finally dried by heating to 320 to 340 DEG F. The apparatus employed is the same as that disclosed in Specifications 866,126, 897,923 and 897,925. As shown in Figs. 1 and 2, a drum 7 is supported by and rotated with an axial pipe 21 which rests on rollers 5 carried by support 2. Inside the drum the tube 21 carries a concertinalike arrangement of annular dished members 26 peripherally joined to form a series of chambers communicating with the interior of pipe 21 through perforations 25. A gas burner 22 delivers a blast of hot combustion products into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26. The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the container, by means of pipes 30. Tubes 8 are provided with exhaust passages 31 having a terminal elbow whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhaust 31 in contact with the exterior of the drum 7. Gypsum is fed to the drum through removable closures such as 11 and the steam formed by dehydration is vented through valves 13. As shown in Fig. 2 the valves 13 are operated by a lever 16 which abuts a valve-operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.

599,999. Refrigerating. KRAMER TRENTON CO. Sept. 27, 1945, No. 25111. Convention date, Nov. 7, 1944. [Class 29] The evaporator 15 of a compression system is defrosted by hot gas supplied direct from the compressor 1, the gas being condensed in the evaporator during defrosting and the liquid passing to a heat storing element 5, 18 normally heated by the hot gases, where it is evaporated and flows back to the compressor. The defrosting may be automatically controlled by electric timing apparatus. In normal operation, the gas from the compressor 1 passes through a pipe 4 into a coil 8 immersed in a solution of alcohol or ethylene-glycol in an insulated vessel 5 and thence through a condenser 9, receiver 11 and expansion valve 13 to the evaporator 15, returning by pipe 17, tank 18 and pipe 3 to the compressor. When a solenoid valve 30 is opened by the timing mechanism the hot gases pass by pipe 25 coil 27 beneath a drip tray 47 and pipe 29 tothe evaporator. Condensed liquid refrigerant passes through pipe 17 to the hot tank 18 where it flashes into vapour and returns to the compressor. The coil 27 prevents freezing of the drip water. A pipe 51 of small bore returns any oil from the bottom of the tank 18 to the compressor.

Film-forming organic materials
|
en
|
The tendency of certain organic, film-forming compositions to corrode metal processing apparatus is removed by adding 0.05 to 3 per cent, by weight of the film-forming material, of a hydroxy compound having a carbon to carbon triple bond. Examples of such compounds are acetylene alcohols and hydroxyalkylation products thereof, e.g. propargylic alcohol, 1,4-butindiol, and their hydroxyethyl ethers and poly-hydroxyethylation products. The corrosive constituent may be the film-forming material itself or another material such as ammonium nitrite, in the form of a mixture of sodium nitrite and an ammonium salt, used for expanding the composition into porous shapes. The film-forming materials include polymers and interpolymers of vinyl chloride, vinylidene chloride, vinyl esters and acrylic esters; and cellulose esters, e.g. the acetate. Plasticizers, e.g. dibutyl and dioctyl phthalate, may be included.

688,763. Washing drinking glasses and the like. WADE & SON, Ltd., J. T., WADE, S. C., and MOONEY, F. L. H. Oct. 2, 1950 [Sept. 30, 1949], No. 25176/49. Class 138 (i). [Also in Groups XXIV and XXX] A drinking glass and like washing machine comprises a conveyer 13 having a pair of parallel belts 15,16, Figs. 3 and 4, on which glasses are placed inverted, water nozzles 41, 42, 43, 44, Fig. 2, to direct jets upwardly between and/or on opposite sides of the belts, to wash the inside and outside of each glass, and an injector, Fig. 5, for continuously introducing bactericidal or detergent liquid into the water before it reaches one or more of the nozzles. The machine, Fig. 2, comprises a sheet metal casing 10 formed with an opentopped tank 11 having a drain 12 and in which the endless conveyer 13 is removably mounted. The conveyer 13, Figs. 3 and 4, includes a base 14 of inverted channel section. The belts are driven from a friction clutch 25, Fig. 2, mounted with its axis parallel to the length of the conveyer. One part of the clutch is a plug 39, Figs. 3 and 4, carried by a worm shaft 24 mounted in a worm housing 26 on the conveyer. The shaft 24 drives through reduction gearing a shaft 27 which drives two pulleys 28, 29 carrying the belts 15, 16. The plug 39 is surfaced with friction material and is engageable in a sleeve 38 carried by a driving shaft 23 driven by belt and pulleys from a motor 19 mounted under the tank 11. The conveyer base 14 rests at one end on the tank bottom, at 40, but at the other end the weight is taken by the clutch 25. Should the clutch parts become slack due to wear of the friction material, the drive will be transmitted due to sideways pressure between the sleeve and plug. In a modification the sleeve 38 carries three or more longitudinal ribs spaced around its internal cylindrical surface and projecting inwardly therefrom. These ribs engage the friction material, preferably rubber, of the plug 39. The ribs may be formed by brazing or otherwise securing metal pins longitudinally along the internal surface of the sleeve. The top 17 of the base 14 is provided with holes 45, 46, 47 and 48 through which jets of water are projected upwardly from the nozzles. Washing water is supplied through a pipe 70, Fig. 5, to the injector body 71 which is connected at 82 to an inlet 54 of the machine (see Fig. 2). Bactericidal or detergent liquid is supplied to the injector through a pipe 79 from a reservoir (not shown). The inlet 54 communicates with a combined valve and distribution manifold 55 operable by a handle positioned outside the casing 10. The manifold supplies cold water to the nozzles 42, 43, 44, by a pipe 59, and to an electric heater 63 by a pipe 60, the heater connecting with the nozzle 41. The water pressure in the manifold 55 communicates by a pipe 61 with a diaphragm 65, the movement of which actuates a mercury switch 64 to close the electric circuits of the heater, motor 19, and a lamp 53 in a transparent tunnel 49 removably supported over the jets on projections 50 on the sides of the base 14. Baffles 51 and hanging gates 52 are provided in the tunnel.

Photographic emulsions
|
en
|
The preparation of interpolymers of acrylic or an a -substituted acrylic acid and an acrylic acid or a -substituted acrylic acid amide is described for use in photographic emulsions comprising a light-sensitive material dispersed in a thermal-reversible gel containing gelatine and the interpolymer. Terpolymers may be used by including acrylic acid esters or vinyl esters in the interpolymerization mixture, and alcohol groups may be introduced into the terpolymers prepared from vinyl esters by hydrolysing or partially hydrolysing the terpolymer formed. Preferably, the interpolymer components contain polar substituents, specified are hydroxyl, amino, amide, formyl, carboxyl and nitrile groups. The interpolymerization is preferably carried out in aqueous emulsion at a pH of 4-9 in the presence of an oxidizing catalyst. Products containing carboxyl groups may be partially esterified with ethylene glycol or glycerol. The gel may be hardened by addition of aluminium and chromium ions and its permeability to water increased by addition of polyvinyl alcohol. Examples are given of the interpolymerization of methacrylic acid and methacrylamide with or without the addition of methyl acrylate. Specification 626,626 is referred to.

Improvement in process of oil-proofing material and product therefor
|
en
|
Fibrous material such as fabric, paper, for example in the form of containers, or the braided covering of wires, is rendered oil-proof by coating one surface with an aqueous solution of a soap having as base triethanolamine or a monovalent metal such as sodium or potassium, which may contain a plasticizer such as ethylene glycol, glycerine, dextrine, or casein, solubilized for example with triethanolamine. Vegetable oils such as cotton seed, rapeseed, linseed, soya bean, olive, peanut, sesame and castor oil, their fatty acids and also sulphonated derivatives or resin or shellac may be used in making the soap which is dissolved in water to form a concentrated solution. Alcohol may be added to prevent foaming and gelling. In examples (1) shellac soap made by boiling shellac with borax solution is mixed with casein solubilized with ethanolamine and a sulphonated vegetable oil soap. (2) Casein is dissolved in an aqueous solution of triethanolamine and mixed with a sulphonated vegetable oil soap into which pigments such as calcium and lead carbonates have been ground. The composition is applied to braided insulated wire. (3) Powdered rosin is saponified with sodium hydroxide and the solution concentrated; sulphonated vegetable oil soap alone or with triethanolamine resinate is then added. Compound paper may be made by using the oil-proof layer as an adhesive to bind together the laminations. The Specification as open to inspection under Sect. 91 describes also the use of ammonium soaps. This subject-matter does not appear in the Specification as accepted.

In a method of producing alloyed or unalloyed cast iron, lithium or lithium with an alkali or alkaline earth metal, magnesium, cerium, silicon, or manganese is added to the molten metal in a quantity sufficient to ensure that the greater part of the carbon in the iron when cast will have a nodular microstructure, adding a graphitizer and casting, the iron to be treated containing so much sulphur that the as cast metal contains at least .02 per cent sulphur after treatment. The lithium may be added as the metal encased in copper or as an alloy with calcium, barium, strontium, magnesium, sodium, or potassium and a preferred alloy is one containing lithium and magnesium in the ratio of 1-3 to 1-30 in the metal as cast. The graphitizing agent may be ferro-silicon, silicon - manganese - zirconium, calcium-silicon, nickel - silicon, or aluminium-calcium-silicon. The iron as cast may contain 2.2-4.5 per cent total carbon, 1-6 per cent Si, 0.001-0.1 per cent Li, 0.001-0.2 per cent Mg, up to 1 per cent P, 0.025-0.08 per cent S and may or may not include up to 40 per cent Ni, up to 5 per cent Cu, up to 2 per cent each of Mo or Cr and up to 2 per cent Mn.

Improvements in or relating to electrical signalling systems

584,358. Signalling over power circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SAVILLE, W. Dec. 29,1944, No. 26064. [Class 40 (iv)] In a signalling system in which high-frequency signalling currents are superimposed on electric supply mains, a test is made immediately prior to signalling to ascertain whether any currents of signalling frequency are present on the line. Any output from the transformer L1, L2, which is tuned to the signalling frequency, is superimposed on the standing voltage on the grid of a gas-filled valve CCT and, if of sufficient amplitude, causes it to fire and operate relay TR. Contact TR1 renders the signalling master switch MS inoperative for as long as the parasitic currents persist, at the same time actuating an audible or visible alarm over lead 14. Alternatively, the glow of the valve CCT may be used as an indicator. If there are no parasitic currents on the mains when the master switch is first operated, relay MSR operates and locks over MSR1 while MSR2 initiates signalling. Thus, disturbances occurring during signalling have no effect. The master switch MS can be made to open a point in lead 14 to prevent an alarm being given by signalling currents and switching can be incorporated at points 10, 11, 12, 13 to make the equipment responsive to other desired frequencies. A contact voltmeter as described in Specification 580,393 may be substituted for the gas-filled valve.

1391118 Recording-apparatus GITAC 7 June 1972 [7 June 1971] 26496/72 Heading G1J Recording-apparatus 1 for writing legends on front and rear discs (or stacks of discs), partially or wholly superimposed, comprises a main recording device 37 driving an associated intermediate recording device 44 wherein the main device has writing means for recording on the rear disc, the intermediate device has means for driving the front disc and legends written on both discs are visible. A viewing window 7 in a fixed front part 2 of the apparatus 1 allows continuous observation of the progress of recording and in embodiments Figs. 2 and 4 (not shown) with wholly superimposed discs, observation of the rear disc is made possible by optical means e.g. prisms or mirrors, one part at least being fastened to a plate 48. The rear disc support 37, free on a fixed shaft 43, is geared to a time controlled electric motor and is secured by a bay onette joint 45, 46, 47 to the casing 44 rotatable on a shaft 49 (fixed by splines or square sections to shaft 43) and covered by the plate 48. An assembly 54, centering and rotationally positioning the front disc, is supported by a pinion 53 engaging a pinion 52 (both rotatably carried by the plate 48), the pinion 51 secured to the casing 44, whereby the front and rear discs are driven in synchronism. A disc, Fig. 6, for use in recording-apparatus on a vehicle has a peripheral zone 67 in which to register graphically a driver's working time, a zone 68 for instantaneous speed recording and an inner zone 69 for distance run. A speed recording member would be arranged to move radially outwards to record increasing speed on this disc, but if greater precision were needed at low speeds a recording member moving radially inward with increasing speed would be arranged to record over a suitably graduated scale in the zone 68. The fixed casing part 2 has an extension 39 serving to position the apparatus on a mounting panel and to prevent rotation with respect thereto. Indication from measuring mechanism, in the rear part of the apparatus I are transmitted to indicating and recording members at the front by shafts extending outside the peripheries of the discs but may be temporarily displaced to facilitate the positioning of the discs.
