Title: Improvements in or relating to the manufacture of artificial filaments, films and the like
IPC: D01D5/04
Filed: 1940-08-05
Abstract: 543,062. Artificial filaments, films &c. DREYFUS, H. Aug. 5, 1940, No. 12587. [Class 2 (ii)] Filaments, films and the like are produced by extruding a solution of a filament-forming polymer or mixture of such polymers in an organic solvent under a pressure of about half an atmosphere. An elongated spinning chamber 1 is shown with heating pipes 2, and an outlet 3 to which suction can be applied to evacuate the chamber to the required degree. The solution of the polymer is fed from the container 4 to a measuring pump 5 by means of nitrogen or other inert gas supplied to the container through the pipe 6. It then passes through the filters 7, 8 to the jet 9, and the extruded filaments 10 are set, while passing through the chamber 1 and are cooled in the lower chamber 11 before being delivered by the roller 12 to the twisting spindle 13. The jet 9 may be filled with heated solution before being applied to the supply pipe, and steam pipes 16 serve as common heating means for the container 4 and the space 14 in which the pump and filters are situated. The solution contains at least 25 per cent. by weight of polymer and the solvent liquid comprises at least one of the following-: phenol, cresol, xylenol, formic acid and acetic acid. The solution also contains a small quantity of an aromatic hydrocarbon.

Title: Improvements in disc brakes
Inventor: BUTLER HENRY JAMES
IPC: F16D65/14
Filed: 1962-04-10
Abstract: 1,034,172. Disc brakes. DUNLOP RUBBER CO. Ltd. April 1, 1963 [April 10, 1962], No. 12753/63. Divided out of 1,033,083. Heading F2E. In a servo disc brake wherein a pair of friction elements are moved obliquely to engage a braking surface of the disc by a brake-applying mechanism adapted to apply a thrust perpendicular to the braking surface, compensating means ensure that each friction element is subjected to an equal thrust. In one embodiment, Fig. 3, pairs of friction pads 29 on each side of the disc which have triangular backing plates 30 are applied against the disc by pistoncylinder device 17, 18. The thrust from each piston 17 is transmitted to each pair of pads by a pressure plate 22 in rocking engagement with a stem 20 of the piston 17 and a pair of thrusttransmitting pivoted levers 32 which abut surfaces 31 of the backing plates 30 and thereby apply a thrust in the direction of movement of the pads the latter being guided by oblique surfaces 28 on the caliper. The pads may be removed through apertures created when the torque-taking members 26 are unbolted from the caliper. In a modification the pressure plates 22 bear directly on the friction pads 29. In another embodiment, Fig. 4 (not shown), the caliper is so pivoted that it can move axially to force the pad 41 secured to the caliper against the disc when the pads 46 are applied against the disc by piston-cylinder device 48, 49. The pads are guided by oblique surfaces 45 and have thrust transmitted thereto by pivoted levers 51 which abut arms 50 formed by the cylinder 49. The latter can rock on the piston 48 so as to ensure that equal pressure is applied to each pad 46.

Title: Arc welding
IPC: B23K9/073
Filed: 1971-05-03
Abstract: 1395318 Supply circuits for arc welding WELDING INSTITUTE 3 Aug 1972 [3 May 1971] 12779/71 Heading H2H A pulsed A.C. arc welding system, in which a main A.C. supply TR2 for supplying heavy current welding pulses is intermittently connected across an arc maintained by a background A.C. supply TR1, comprises a thyristor T1 for temporarily isolating the main supply from the arc at the start of each positive half cycle of arc current so that the background supply voltage reaches a value sufficient to reignite the arc after each negative to positive current reversal. A contactor P1 controlled by a timer determines the duration of the bursts of A.C. welding pulses. The thyristor prevents the high re-strike voltage provided by the background supply from being dissipated in the low impedance of the main supply and the delay in firing the thyristor at the start of each positive half cycle whilst the background supply restrikes the arc is determined by a trigger circuit including two monostable multivibrators and a high frequency astable multivibrator. A diode D1 short circuits the thyristor during the negative half cycles since a high re-strike voltage is not required during this time. In a modification the contactor is omitted and the diode is replaced by a thyristor. Fine control of the welding current is provided by phase controlled firing of the thyristors whilst coarse control is provided by a variable inductance X1. The current in each half cycle may be balanced by varying the inductance in circuit with each thyristor or by connecting the thyristors to different tappings on the transformer TR2.

Filed: 1938-04-29
Abstract: 514,213. Wireless receiving apparatus. BOSCH GES. R. April 29, 1938, No. 12789. Convention date, April 29, 1937. [Class 40 (v)] Tuning of a receiver over the whole of its range from, say, 200 to 2,000 metres, is effected by a single continuous movement of the condenser shaft through 180 degrees, this movement, effecting a simultaneous variation of the inductance by displacement of an iron core and switching over at appropriate points from one coil winding or part winding to another. In the apparatus shown, the operating shaft e drives through a worm f the condenser shaft h and through gearing i, k a screw l which meshes with an insulating block m attached to an iron core c projecting into the coil d. Switching over from one winding to another is effected by a cam or cams v controlling contact springs x and mounted on a shaft u driven from the shaft e by Geneva-type gearing s, t. End-play between block m and screw l is avoided by a transverse wire o passing through the block and sliding resiliently on guides p at its ends, and end-play between worm f and wheel g is avoided by forming the latter as two similar superposed discs connected by a spring q.

Title: Milling machine
IPC: B23F15/02
Filed: 1954-05-04
Abstract: 756,241. Gear-cutting; copy-milling. ETABLISSEMENTS BOUTILLON SOC. ANON. May 4, 1954 [July 4, 1953], No. 12941/54. Class 83(3). A machine for milling elliptical or irregular gears, or workpieces of elliptical or other cross-section, comprises a cutter 12 on a slide 13 movable transversely to the axis of a blank 9, a train of gears 64 interconnecting the slide with a second parallel slide 42 carrying a worm 57 interconnected with the cutter, and a master gear 58 meshing with the worm and coupled with the blank 9. The milling-cutter 12 is mounted in an angularly-adjustable casing 25 on the cross-slide 13 on the saddle 14. The cutter is rotated by a motor 4 through a gearbox 6, a splined shaft 3, helical wheels 23, 24, bevels 20, 21 and gears 18-16. The cutter-drive includes a flywheel 26. The saddle 14 is traversed by a screw 27 rotated, through change gearing 32, from the shaft 3. The slide 13 is moved in and out by oscillation of a shaft 41 carrying a pinion 40 meshing with rack teeth 39 on a block 35 attached to the slide 13 by the handadjustment screw 33. A cam 65 engages a roller 66 adjustable on the slide 42 which carries rack teeth 59 to oscillate a pinion '60 which, through change gearing 64, oscillates the shaft 41 and thus gives a similar or proportionate movement to the slide 13. The cam 65 is shaped to ensure correct meshing of the master gear 58 with the master worm 57 which is mounted and driven in the same way as the cutter. The cam 65 and gear 58 are mounted on the headstock-spindle 11 which carries the work 9 supported additionally by a tailstock 8. The roller 66 is held against the cam 65 by fluid-pressure jacks 70, or other counterweighting means, acting on the slide 13. By changing the gear train 64 and the cutter, varying sizes of gears may be cut from a single cam. If a conventional side-milling cutter is used instead of a hob, work of plain elliptical section is produced. In a modification the cam 65 is dispensed with.

Abstract: 1,166,214. Cooking food under pressure. R. H. ANGOLD. 18 March, 1968, No. 13028/68. Heading B1X. [Also in Division F2] Food, e.g. chicken, is cooked under pressure in a chamber through which hot fat (or other cooking liquid) is circulated by way of inlet 5 and outlet 7, the hot fat being pumped up through pipe 1 from a fat fryer, and being returned thereto via pressure-control valve 10 and an exhaust zone where the fat is separated from vapour, the latter being vented. The cooker contains an imperforate plate which is movable up or down, and acts so that an air-cushion is provided in the upper part of the cooker. The fat is filtered as it flows from the exhaust zone to the fat fryer. Pipe 2 leading away from the circulation pump is connected to by-pass 3, and to control-valve 4 which is connected to cooker-inlet 5 and to drain-pipe 6. The cooking-period is controlled by an automatic timer in the circuit which operates the pump motor. Upon completion of the timer cycle, the pump is automatically shut off. The relief of pressure against valve 4 opens the drain-pipe, and the cooking chamber empties to the fryer via the filter.

Title: Improvements in apparatus for controlling the holding of milk or other liquids during pasteurisation
IPC: A23C3/033
Filed: 1945-05-25
Abstract: 601,462. Pasteurising-apparatus. COW & GATE, Ltd., and MAIN, W. May 25, 1945, No. 13157. [Class 49] [Also in Group XXXV] An apparatus for pasteurising liquids such as milk and beer comprises a holder 1, means for effecting turbulence of the liquid in the holder, e.g. a disc 29 having holes 291 round its flange, an outlet pipe 20 extending into an inner sleeve 21, to prolong the path of the liquid entering by the pipe 18 in its passage through the holder, the outlet pipe being connected to delivery (39) and diversion (40) valves operated by compressed air, the supply valve of which is actuated by a thermosensitive device having a bulb 31 at the outlet side of the holder. Preferably, the delivery valve and diversion valve operate in unison, so that the opening of the diversion valve, upon fall of the temperature below that specified for pasteurisation, e.g. 165 degrees F., to return the liquid to the source of supply, closes the delivery valve; for example, the effect of such fall in temperature on the liquid in the bulb 31 and consequent movement in a Bourdon spring connected therewith is to open a valve 54 connected to a supply of compressed air, the compressed air flowing into a cylinder 53 pushes up a piston 52 therein, and the consequent movement of a lever 45 on a spindle 47 opens the diversion valve 40 and, simultaneously, through an eye-bolt coupling 41 between the valves 39 and 40, closes the delivery valve 39, and the effect of restoration of the specified temperature at the bulb 31 is to cause closure of the compressed air valve 54, allow a spring 154 to push down the piston 52, and through the agency of the lever 45, close the diversion valve 40 and simultaneously re-open the delivery valve 39. Preferably the apparatus includes in addition provision for delaying the closure of the valve 54, and hence the closure of the diversion valve 40, upon restoration of the specified temperature at 31, in order to ensure complete clearing through the valve 40 of liquid from the holder 1 and the pipe 20 before flow through the delivery valve 39 is restored. Steam heating apparatus may be employed for heating the liquid undergoing pasteurisation, the supply of steam being increased on decrease of temperature at the bulb 31 below the specified pasteurisation temperature and the supply of steam being decreased on rise of temperature at the bulb 31 above the specified temperature, e.g. by the opening of a valve 56 to a supply of compressed air to exert a throttling action on a diaphragm-controlled valve for the supply of steam.
