Title: Improvements in Fixed Ammunition for Non-recoil Guns.
Inventor: SPEAR LAWRENCE YORK
IPC: F42B5/05
Filed: 1918-11-05
Abstract: 130,237. Spear, L. Y., and Davison, G. C. Nov. 5, 1918. Ordnance, design. - Relates to non-recoil guns as described in Specifications 23512/11 and 18268/13, adapted to discharge a mass rearwards to balance the forward ejection of the projectile, which arrangement is specially suitable for use on aircraft. According to the invention, the cartridge case E is made in one with or is fastened to the mass E<1> and both the cartridge case and the projectile C are made with rifling bands e<3>, c respectively, to cause them to robate in opposite directions, both front and rear barrels being similarly rifled. Projections such as bevelled rings c are formed on the case, and the wall of the case between these rings is perforated to allow the powder gases to pass to the outside of the case to prevent it sticking in the gun. A stud F on the cartridge is adapted to fit into corresponding notches in the gun to ensure the radial primer G being in line with the firing-pin D of the gun. The projectile has a flat rear end and a flat or cupshaped nose to ensure a straight course when the projectile falls in water at a high angle.

Title: Improvements in and relating to hydraulic power transmission means
IPC: B23B47/22
Filed: 1931-06-24
Abstract: 381,547. Gear-wheel pumps. JONES & LAMSON MACHINE CO., Springfield, Vermont, U.S.A.-(Assignees of Flanders, R. E. ; Cherry Hill, Vermont, U.S.A.) June 24, 1931, No. 18277. Convention date, July 15, 1930. [Class 110 (ii).] In hydraulic power transmission means, especially for traversing tool carriages, pressure liquid is supplied by a pump having variablespeed driving mechanism, which is controlled by means responsive to the pressure on the delivery side. The operated machine comprises a cylinder 10, Fig. 1, a distributing valve 22, a metering device 28, which may be constructed as in Specification 352,809 and is capable of being bye-passed by a valve 31, and a pump 25. The pump driving mechanism comprises a slidable pinion 60, Figs. 12 and 18, on the pump shaft 59, a pinion.63 rotatable on a shaft 61, a pinion 70 fixed on a driving shaft 71 and a pinion 73 rotatably mounted on the shaft 71. High speed drive is obtained by moving the pinion 73 axially so that it is clutched to the shaft 71, and the drive takes place through 73, 60 ; for low speed, the pinion 73 is freed, and the pinions 60, 63 clutched together, so that the drive takes place through 70, 63, 60 ; no drive is obtained when both clutches are out. The position of the clutches is determined by levers 110, 126, actuated by a cam 107, Fig. 13, on a shaft 106. The pump delivers past a non-return valve 57 to an accumulator cylinder 82 having a plunger 84 loaded by a spring 140, and thence to the valve 22. When the valve 22 admits liquid to the cylinder 10, with the metering device bye-passed, the plunger 84 is moved to its extreme left-hand position, and moves a rod 97 so that a rack 102 turns the shaft 106 to drive the pump at high speed. When the metering device is interposed, the resistance created moves the plunger 84 to the right to cause the pump to be driven at low speed. Further movement of the plunger renders the pump drive inoperative and the accumulator alone supplies liquid until such time as the plunger has returned to the low speed position. In order to prevent hunting, the cam 107 has a projecting member 150 engaging a roller on a spring pressed lever 153, so that the cam is not turned until there is sufficient pressure to allow the member 150 to snap past the roller.

[Also in Group XXXIII] Thrust reverser doors 1 of a jet propulsion engine are moved by at least one actuator 10 and are latched in the inoperative position by mechanism 3 each including an actuator 11 fed, with actuators 10, from a common supply, control valve 9 and pressure source 7, movement of the doors to the inoperative position initiates actuation of actuators 11 to latch the doors in the inoperative position. The mechanisms 3 comprise a hook 12 and crank 16 pivoted at 14, 17 respectively, to beam 15 and interconnected by rod 18; stops 29, 32 on crank 16 co-operate with stops 30, 33 on beam 15 and with overcentre mechanism 35 to define limit positions of the hook 12. A lever 24 pivoted to crank 16 at 26 is connected via a slider 21 to a piston 41 in actuator 11. With valve 9 as shown, fluid is supplied via conduits 58, 54 to move pistons 65 of actuators 10 to move doors 1 to the inoperative position. The door stirrup 4, Fig. 2, engages and rotates hook 12 to move piston 41 to the left, to uncover port 42 and fluid then moves piston 41 to fully engage the hook 12 with stirrup 4, the over-centre mechanism 35 holding the hook engaged and the stops 32, 33 in abutment, Fig. 3, not shown. The piston 41 moves a piston 47 to uncover ports 44, 45 to allow the fluid in conduit 58 to flow back to reservoir 8, an adjustable orifice 6 maintaining a pressure in pipe 58 at a sufficient low level to hold the doors in the latched position. Fluid also flows to reservoir 8 via passages 65 in piston 45 and conduits 56, 59, 64. For thrust reversal, valve 9, which may be operated by a throttle lever, is moved to the dotted line position, Fig. 1, to supply fluid via conduits 59, 56 to firstly move pistons 41 to the right to rotate hook 12 clockwise until stirrup 4 is disengaged, the overcentre device 35 moving crank 16 until stops 29, 30 abut. Springs 51 move pistons 47 to close ports 44, 45 and fluid moves the piston of actuators 10 to move the doors 1 to the operative positions. Pistons 41 close ports 42. A simpler fluid pressure system is given in Fig. 4, not shown.

Title: An electronic phase failure, earth leakage and unbalanced overload protection device
IPC: H02H3/34
Filed: 1953-07-03
Abstract: 734,326. Protective cut-out arrangements. CHAPMAN, G. S., and GOODALL, J. S. H. Feb. 4, 1954 [July 3, 1953], No. 18430/53. Class 38 (5). An unbalance-protection device for a system having any number of phases comprises current transformers in each phase with their secondaries in series and connected to a voltage-doubler and rectifier network and to the control grid of a multi-electrode, highvacuum valve which, on unbalance, operates control relays to cut off the supply. In the arrangement shown, when a switch S7 is closed, at ransformer T2 supplies current to the series-connected heaters of valves V1, V2 and through a rectifier Q3 and smoothing circuit C3, C4, T1 applies high tension to the anodes of the valves. The diode V1 conducts and energizes relay coil X1 which closes contacts S2 in the circuit of the contactor closing coil T6 and opens contacts S3 to extinguish a warning lamp N2 to indicate that the protective circuit is free from fault. The pentode V2 remains non-conducting due to the standing negative bias on the control grid derived from resistors R2, R3, so that relay coil X2 is not energized and the circuits of the coil T6 and an indicator lamp N1 are completed at contacts S5. The contactor closes. In the event of unbalance in the protected circuit, the resultant voltage produced by open delta-connected current transformers T3 ... T5 is applied to the control grid of the pentode V2 as a positive D.C. potential by means of the rectifying and voltage-doubling circuit C1, C2, Q1, Q2. The pentode V2 conducts and the relay coil X2 is energized to open contacts S5 to cause the opening of the contactor, to close contacts S4 to operate indicator lamp N3 and the warning bell, and to close contacts S6 to complete a holding circuit through a resistor R5 for the relay coil X2. Resetting is effected by opening and closing S7 and remote control warnings and operation may be obtained by connecting indicators and a switch in parallel with the indicators N, &c. and S7 respectively.

Switches, latching.-A switch lock to be applied to the ignition circuit of a motor car or cycle to guard against theft has a permutation lock composed of a number of disks with a notch in the interior periphery to admit a spring-operated lever when the notches coincide, the circuit being completed by the lever or by contacts carried by the disks. In the form shown in Fig. 1, the letter disks 8, 9, 10, 11 rotate upon a tubular spindle 1. The disks 8, 9, 10 carry a fixed plate contact on one face and a spring-plunger contact on the other face. The disk 11 has a spring- plunger contact on each face. When the correct letter combination is obtained the contacts are in line and connect terminals 3 with terminals 6 through the contact plates 7 on the end plate 5, Fig. 3. In this position, the pivoted lever 16 is pressed by a spring 20 through a slot in the tube 1 into notches in the contact disks to hold the links in position. The lock is released by raising the end 21 of the lever. In a modification, the disks 8 - - 11 do not carry contacts, but the lever 16 acts as a switch lever and completes a circuit with the contact 23, Fig. 6, when the spring 20 causes it to enter the notches in the disks. The lock in this case is released by rotation of the end disk 11 which carries a cam to raise the lever.

Abstract: 653,697. Electrolytic treatment of dissolved gases. BAULE, M. E. A. July 9, 1948, No. 18575. [Class 41] [Also in Group XL (a)] Gaseous organic substances, particularly fuels, are treated by an electric discharge in the presence of an alkaline solution of caustic soda or potash or water-soluble salts of sodium or potassium. An aqueous solution is mixed with the alkaline solution or if the gas is not soluble a foam formed by the gas and alkaline solution is subjected to the discharge. A reaction chamber 13 which acts as one electrode is connected by a pipe 14 to a supply chamber 18 containing a solution of, e.g., sodium resinate and 2 per cent of pure caustic soda, the other electrode 26 having a large number of sharp points of high melting-point metal directed towards the surface of the liquid where a foam is created by introduction of gas through an immersed perforated box 15. Excessive pressure developing in the reaction chamber causes a drop in the liquid level by transfer of solution back to the supply tank, the foam then losing contact with the electrode. A number of chambers 13 may be arranged in series. In another embodiment the foam is produced by a paddle and passes to a separate reaction chamber with similar electrodes or with two electrodes within it.
