Patent GB-580416-A (GB)
Title: Manufacture of solid and semi-solid polymers from aliphatic mono-olefines
IPC: C08F10/00
Filed: 1943-12-03
Abstract: In the manufacture of solid and semi-solid polymers and interpolymers of aliphatic monoolefines, e.g. ethylene, propylene and isobutylene, at elevated temperature and pressure, preferably in the presence of oxygen or a peroxygen-type catalyst, the temperature, pressure, proportion of olefine converted and nature of the gaseous phase are so correlated that the product is entirely dissolved in the gaseous phase and is removed therein from the reaction zone.  This may be accomplished by (a) limiting the time during which the substances are at reaction temperature and pressure, (b) restricting the amount of catalyst used, (c) in a continuous process, passing the gases through the reaction zone at such a rate that only such amounts of product are produced per pass that they are held in the vapour phase, (d) using exceptionally high pressures, or (e) polymerizing in the presence of other substances, e.g. benzene, which enhance the solubility of the product in the gas.  The process is applicable to copolymerization of olefines with styrene, vinyl acetate, vinyl halides, vinyl ethers, N-vinyl amides, methyl vinyl ketone, acrylic, methacrylic, itaconic, citraconic, crotonic, maleic and fumaric acids, their esters, acid halides and anhydrides.  Other substances, e.g. water, benzene, isooctane, chlorobenzene, nitrogen and methane may be present.  The product may be separated by lowering the temperature and/or pressure of the exit gases, with recycling of the unreacted gases.  Specifications 471,590, 497,643 and 8070/40 (as open to inspection under Sect. 91) are referred to.

Title: Improvements in or relating to looms for weaving pile fabrics
IPC: D03D27/06
Filed: 1946-07-09
Abstract: 621,141. Pile fabric looms. WOODWARD, GROSVENOR & CO., Ltd., and LOCKLEY, J. F. July 9, 1946, No. 20441. [Class 142 (ii)] In a loom in which pile warp is looped over pile wires 16, the pile wires are flat strips mounted between grooved bars 38, 40, the bar 40 being oscillated endwise to rock the wires, thereby moving their tips 34 from one side to the other of the spaces in a comb 29 : the comb is also oscillated in the same direction as the tips 34 but through a smaller' distance'.. After lowering the pile warp threads 20 down one side of the wires 16 (to position 20b), picks 57 of weft are inserted. The wires 16 and the comb 29 are then moved to bring the tips 34 into contact with the teeth 30 on the same side of the wires as the threads 20. Heels 32 prevent the threads from passing under the wires so that when the threads are lifted, they slide up the side of the wires on which they were lowered ; in doing so, the threads deflect the tips 34 away from the teeth 30 until the threads have cleared the wires. whereupon the tips spring back into contact with the teeth. The threads are then on the opposite side of the wires, so that the next lowering of the threads forms pile loops over the wires. It is stated that the threads 20 may alternatively pass under the wires and thus be wrapped round them continually in the same direction.

Title: Improvements in presses for the extrusion of lead and lead alloys
IPC: B21C33/02
Filed: 1945-08-10
Abstract: 597,115. Extruding. BRITISH INSULATED CALLENDER'S CABLES, Ltd., and SPENCER, J. A. Aug. 10, 1945, No. 20533. [Class 83 (iv)] In a press for the extrusion of lead and lead alloys, comprising a ram working through one end of a container to extrude through a die at the other end, the molten metal enters the container from a vessel at a higher level through a port in the container wall, the opening and closing of the port being effected by a power actuated valve which keeps the port closed during the extrusion stroke. The container 1 is mounted on a die box supported on a fixed base and the ram 3 is operated hydraulically. Molten metal from a vessel 43 passes by way of a heated pipe 26 to a metal block 20 bolted to the wall of the container. The passage of the metal from the pipe 26 into the container is controlled by a rod 17 passing through a bore in the block 20 and through a port 14 in the container and operated by a hydraulic cylinder 37. The inner portion 16 of the port 14 is of smaller diameter and the two portions are connected by a taper portion 15 against which the conical end 18 of the rod 17 is adapted to seat to close the port. In this closed position, the end of the rod is flush with the inner surface of the container so that only a thin wall of solid metal can obstruct the inner end of the port when the rod is withdrawn to admit a new charge. Bolted to the block 20, but separated from it by an insulating layer, is a water-cooled casing 27 formed with longitudinally spaced annular grooves 30 adapted to fill with solidified metal which acts as a seal or gland. The block 20 is kept heated by a burner 34. The lowermost position of the ram is indicated by the line 48. In order to increase the rate of cooling of a new charge prior to the next extrusion stroke, the ram is formed with a central tapering opening so as to leave an upstanding column 50 of solid metal on its upward stroke and the port 14 is offset from the radial position so that the entering metal is given a circulatory motion around the column. To speed up the operation still further, the stroke of the ram may be shortened and its lower end provided with grooves adapted to fill with solidified metal to form a packing.

Title: Jet engine assembly
Inventor: KERRY THOMAS HENRY
IPC: F02K1/60
Filed: 1961-06-07
Abstract: 942,593. Jet deflectors. ROLLS-ROYCE Ltd. June 4, 1962 [June 7, 1961], No. 20647/61. Heading B7G. [Also in Division F1] A jet engine assembly for use on a supersonic aircraft is provided with a convergent-divergent final nozzle, there being means including an apertured portion of the aircraft structure, for introducing when required, into the nozzle an annulus of air so as to alter the effective crosssectional area of the throat of the nozzle, the apertured portion of the aircraft structure being disposed adjacent the throat so that atmospheric air may be drawn directly therethrough and into the throat, there being also provided means for opening and closing the apertured portion. Thrust reverser members are also provided and they may be moved into and out of a thrustreversing position in which they direct the jet gases through the apertured portion of the engine casing. In Figs. 1 and 2, the jet pipe 10 of a gas turbine engine is mounted within aircraft structure 11, the jet pipe terminating in a convergent portion 12 which together with the divergent portion 13 forms part of the aircraft structure, constitutes a convergent-divergent nozzle. A pair of oppositely-disposed ports 18 are provided between the nozzle portions 12, 13 and a pair of flaps 15, 16 which are pivotally mounted at 14 is disposed adjacent the openings or ports. The flaps constitute a thrust reverser device and when moved to the position shown in Fig. 2 deflect the gas stream forwardly through the openings 18. The openings 18 are controlled by axially-movable doors 21, there being two doors associated with each opening. The doors are axially movable on rollers 20. Air under pressure such as ram air or air from the engine compressor may be supplied through a pipe 22 under control of a valve 23 to a space between the jet pipe 10 and a surrounding shroud 24. In operation, when the aircraft is travelling at a speed of, say, 1.3 Mach, the doors 21 and the valve 23 are maintained closed, but at speeds below this value it is necessary to reduce the effective cross-sectional area of the throat of the nozzle 12, 13. The doors 21 are therefore opened whereby the ejector effect of the gases passing through the nozzle will draw atmospheric air in through the ports 18 to form an annulus of air at the throat, thereby serving to reduce the effective cross-sectional area of the throat. At low flight speeds, the valve 23 may also be opened, whereby further air is admitted to the throat thus acting to reduce still further the effective cross-sectional area thereof.

Title: Improvements in or relating to the reduction of zinciferous materials
IPC: C22B19/04
Filed: 1927-08-08
Abstract: 300,519. Jackson. L. Mellersh-, (New Jersey Zinc Co.). Aug. 8,1927. Roasting furnaces; charging.-In a method of reducing zinciferous materials a porous charge of agglomerates of the material and a reducing agent passes progressively through a horizontal, externally heated reducing chamber without substantially breaking down or relative movement of the agglomerate. The reducing chamber is relatively long and narrow and of large capacity. The charge is fed to the reducing chamber 10 from a hopper 39 and carried through the chamber by a pan conveyer 30 which is covered by a bed of fine material fed from a hopper 37. A layer of spent agglomerates fed from the hopper 38 prevents the charge from being embedded in the fines. The chamber is heated by gaseous fuel in an overlying flue 12. The zinc vapour is led off by conduits 44 to a number of condensers 51 which are mounted on rails 58 and may be of the type described in Specification 295,115, [Class 82 (i), Metals, Extracting &c.]. The fumes may be led off to suitable apparatus for the production of zinc dust or zinc oxide. In a modification, Fig. 7, the charge is preheated by exhaust gases from the regenerator entering the the 12' at 72 and leaving at 81. The agglomerates are fed by a conveyer 75 from the briquetting-press 74 on to a screen 76 and are dried by hot gases in a pipe 79 which passes beneath the screen. Reference has been directed by the Comptroller to Specification 298,921.

Title: Improvements in or relating to electric discharge apparatus for rectifying alternating currents
IPC: H01J1/42
Filed: 1929-07-08
Abstract: 336,563. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 8, 1929. Vacuum tubes; metallic-vapour apparatus.- Apparatus for rectifying alternating currents comprises a gas-discharge tube in which an incandescent cathode, prsferably an .oxide cathode, and one or more anodes are located in separate chambers, means being provided to maintain in the anode chambers a lower pressure than in the cathode chamber. The tube may be operated at high voltage, e.g. 10,000 volts, and disintegration of the cathode is reduced by the high gas pressure in the cathode chamber. As shown, an incandescent cathode 3 and a graphite anode 5 are contained in chambers 2, 4 respectively. Mercury is vaporized from a cup 9 by means of an electric heater 10 and the vapour is condensed in the anode chamber by means of cooling air from a fan 11. The mercury in the cup 9 may be heated to ensure a vapour pressure of some mm. in the cathode chamber. Transfer of heat between the chambers is prevented by a metal or asbestos screen 20. Condensed mercury is returned to the cup 9 by a channel 6 or by separate tubes. The circulation of vapour between the chambers may be impeded by contracting the diameter of the channel 6 or by screens fitted therein. To ensure quiet operation, nickel wires connected to the anodes and extending towards the cathode may be mounted on the tubes as described in Specification 311,254. The construction may be modified for use with multiphase currents by providing a number of anodes mounted in separate chambers. The discharge may be initiated between an auxiliary eleotrode 13 and the cathode 3 by means of a direct current obtained from a rectifier 14, the anodes 17 of which are connected through resistances 16 to the mid-point of a transformer secondary winding 8 supplying the cathode filament current.
