Title: Improvements in or relating to apparatus for projecting rounds of ammunition
IPC: F41A9/34
Filed: 1947-02-03
Abstract: 626,923. Rocket launching apparatus. MOTLEY, L. Feb. 3, 1947, No. 3181. [Class 92 (ii)] Rounds of ammunition, particularly rockets, are discharged by an apparatus comprising two containers 1, 2, for the rounds 3, a breech element 6 adapted to reciprocate to and from two positions, and means whereby the element 6 as it reciprocates alternately conveys rounds from each container to a location where they can be discharged. In the construction shown, the two containers 1, 2 extend upwardly from a chamber 11 and each is provided with pushers 5, as in Specification 592,714, which urge the rounds downwards towards the element 6. This element is formed with channels 7, 8 for receiving the rounds, the channels being so arranged that when one is in a position to receive a round from a container the other is positioned in line with a launching tube 4 extending from the front wall of the chamber and with an exhaust gas escape tube 15 at the rear. The element 6 is made to oscillate to and from its two positions by two pneumatic units each comprising a tube 16 which passes through the element 6 and which is divided by a partition 17 into two cylinders to which air is supplied by pipes 21 through hollow fixed piston-rods 19 and pistons 18. The control of compressed air is so arranged that it tends, after driving the element in one direction, to cushion it and return it, such return motion being initially prevented by catches 39. When a round is launched it engages with and moves a pivoted shoe which, by a pawl-and-ratchet device, moves a cam for controlling an electric switch arranged under a cover 73. This switch is in circuit with a pair of solenoids which move a valve controlling the supply of pressure fluid to pistons which through cam slides serve to unlock the catches 39, thus permitting the element 6 to move to its new position. The downward motion of the rounds in the two containers is controlled by arms 101 on spring- driven shafts 100, which arms project into the containers to hold the lowermost round. Rotation of each shaft 100 is normally prevented by a pawl 104, but is momentarily deflected by a pivoted arm 105 on the element 6 to release a round into the channel which is moving into a position to receive it. Thus in Fig. 2, a surface 113 on the right-hand arm 105 will, when the element 6 moves to the right, engage a flange 109 on the adjacent pawl 104, thus releasing a round in the container 2, while at the same time the left-hand arm 105, by reason of the shapes of the parts 113 and 109 will be depressed against spring action by the left-hand pawl 104, thus causing no release of a round in the container 1. Specification 589,177 is referred to. The Provisional Specification describes also a modification in which the element 6 oscillates about an axis parallel to the launching tube, and refers to Specification 588,920.

Title: Cylinder locks
IPC: E05B17/14
Filed: 1954-03-20
Abstract: 775,098. Barrel locks. BIRO, L. J. March 20, 1954, No. 3238/54. Class 44. An anti-picking device in a revolving barrel lock of the pin tumbler type comprises a spring- loaded plunger mounted in the barrel which screens the tumblers by blocking the keyway and, when deflected to clear the keyway, locks the barrel. The plunger 21, Fig. 7, is mounted on a spring arm 26 secured in the barrel 12, and bevelled faces 18, 19, on the side of a key 16 deflect the plunger into engagement with a recess 22 in the lock cylinder 10 when the key is inserted or withdrawn. A slot 17 in the key 16 permits the plunger to free the barrel when the key is fully inserted. A depending flange 24 on the plunger 21 screens the lower part of the keyway. The outermost pin tumblers and locking pins are loosely fitted in their guideways to prevent picking the lock by lodging the locking pins on an arris of the barrel 12.

Abstract: 395,056. Thermionic valves. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and KAPTEYN, P., 5, Schwalbacherstrasse, Friedenau, both in Berlin. Feb. 4, 1932, No. 3305. Convention date, Feb. 16, 1931. [Class 39 (i).] In a thermionic valve having three or more electrodes, one electrode is positioned intermediate two others which have different potentials and given sizes and positions, in such manner that the sum of the two capacities formed between the intermediate electrode and the outer electrodes is a minimum. In the case of cylindrical electrodes, it is shown that the radius of the intermediate electrode is the geometric mean of the radii of the other two. The invention is described with reference to resistance capacity coupled screen grid valves. In the first valve the screen grid SG1, Fig. 2, is placed as far as possible from the anode A. In the second, the radius of the control grid G2 is the geometric mean of the radii of the cathode K2 and the screen grid SG2. In a modification, resistance capacity coupling is employed between valves having screen grids and space-charge grids. In the first valve the screen grid SG1, Fig. 4, is placed as far as possible from the anode A1 and the radius of the control grid G2 is the geometric mean of the radii of the screen grid SG2 and the space charge grid RG2. The coupled systems together with circuit elements may be housed in a single envelope.

Abstract: 401,262. Valve circuits. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ;. 2, Friedrich Karl-Ufer, Berlin.) Feb. 6, 1932, No. 3604. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 8, 1932]. [Class 40 (v).] In circuits employing valves the cathodes of which are directly heated by alternating current the anode voltage supply also being alternating the relative phase position of the heating and anode currents is so chosen that the effective value of the sum of the heating and anode currents is a minimum or approximately so. This desideratum is illustrated in Fig. 2, the shaded portion a being the anode current of a single phase rectifier and h the cathode heating current ; the sum of the two is a minimum when they are 90‹ out of phase, as shown. Fig. 4 shows a three-phase rectifier arrangement in which the anode transformer 20 is connected in star-star, the heating current for valve 8 being taken across the phases 4<1>, 5<1> giving 90‹ phase displacement between the cathode and anode currents as shown by vectors 6, 121 in Fig. 5. Where such connections are impracticable, as with delta-star connection of the anode supply transformer, phase changing means may be inserted in the leads from the anode to the cathode transformer, Figs. 6 and 7 (not shown). Alternatively, a polyphase heating transformer with star-connected primary and separate secondary windings may be used with a deltastar-connected main transformer, Figs. 8 and 9 (not shown). Figs. 10 and 11 show the application of the invention to a six-phase rectifier system comprising three double-anode valves. In this case the phase voltages 6<11>, 6<111> are co-ordinated with the heating voltage 12<1>, Fig. 11.

A method of forming a body 12 of insulating material between a cylindrical member 1 and a surrounding metal sleeve 4 (e.g. forming an armouring seal on an electric cable) so as to minimize penetration of moisture therebetween comprises applying a sleeve 11 of elastomeric material on to the cylindrical member, with an expanded fit, so that it lies at least partly within the metal sleeve, and introducing insulating material, e.g. epoxy resin, into the space between the two sleeves to form a cast or moulded body which adheres to a complete annular part of both sleeves. The cylindrical body may be of plastics or metal and the sleeve of neoprene or rubber. To prevent the cast insulation from pulling the elastomeric sleeve away from the cylindrical body due to shrinkage an annular portion of the sleeve may be coated with an adhesion inhibiting substance. An end seal for an electric cable with a plastics sheath 2 and helically applied armouring wires 3 comprises a metal cylinder 4 with a flanged end 5, the ends of the armouring wires being lifted clear of the sheath, bent outwardly, and clamped between the flange 5 and a metal ring 6.
