Title: Improvements in and relating to fire arms
IPC: F41A17/14
Filed: 1946-02-22
Abstract: 608,419. Firearms. PODSEDKOWSKI, J., WHEELER, W. E., and MITCHELL, S. S. C. Feb. 22, 1946, No. 5624. [Class 92 (ii)] A device for preventing a round of ammunition being fed into the barrel chamber of a firearm if the case of the preceding round has not been withdrawn, comprises a rotary cylindrical member 7 having abutments 8 which are brought into the path of the breechblock entraining member by rotation of the member 7. In the construction shown, a casing 2 connected to the breech-block recoils against the action of a spring 5 when a shot is fired. On the fixed gun body 3 is mounted the member 7 which is urged by a spring 12 into a position in which its abutments lie in the path of lugs 6 on the casing 2. Normally a roller 16 on a spring-controlled pivoted beam 14 depresses a lever 10 on the member 7 against the action of spring 12 so that the abutments 8 are in the inoperative positions. In operation, when a cartridge is introduced into the chamber it engages and lifts a pin 22 which through a plunger 19 raises the beam 14 and enables the member 7 to rotate to bring abutments 8 to their operative positions. The abutments 8 at this stage however, are past the lugs 6 and the round is fired. On recoil, the case is extracted and the parts assume their original position with the abutments 8 clear of lugs 6. If, however, the case is not extracted a ramp 9 will on recoil engage the member 7 and move it against the action of spring 12, and on the subsequent forward movement of the breechblock casing 2 the abutments will engage the lugs 6 and prevent the loading of a fresh round.

Title: Improvements in or relating to speed and direction indicating mechanism
IPC: G01P11/02
Filed: 1939-02-20
Abstract: 525,424. Speed indicators. OTTWAY & CO., Ltd., W., and OTTWAY, W. R. Feb. 20, 1939, No. 5661. [Class 106 (iii)] [Also in Group XXXVIII] Means for indicating the speed and/or direction of motion of rotating members comprises an instrument having two pointers, one of which is moved over a scale to indicate the speed or mean speed of the members in one direction and the other of which is moved over a scale to indicate the speed in the opposite direction, the position of each pointer being dependent on a controlling member which moves in accordance with the speed with a regular interruption for return to zero. the pointer, however, remaining in its set position on each occasion. Each rotating member drives a cam 6 or 6<SP>1</SP> when rotating forwardly through a free wheel and a cam 10 or 10<SP>1</SP> when rotating backwardly. Switches operated by these cams cause pawls 13 and 13<SP>1</SP> and 17 and 17<SP>1</SP> to operate wheels 14 and 14<SP>1</SP> and 16 and 16<SP>1</SP> and cause, through differentials D and D' and spring, drives 20 and 20<SP>1</SP>, wheels 22 and 22<SP>1</SP> to be rotated at rates proportional to the mean speeds of the rotating members, forwards or backwards. The wheels 22 and 22<SP>1</SP> actuate pawls such as 29 which advance a wheel 30 on the axle 31 'of their particular pointer 35. At regular intervals a wheel 34 rigidly connected to pointer 35 is freed by actuation of a pawl 42 and is moved by a spring 41 to bring a peg 33 into contact with peg 32. The pawl 42 is then engaged and a pawl 40 withdrawn which permits a spring 37 to zeroize wheel 30. Zeroization of the pointer at each period is thus avoided. The two pointers, one for each half of the apparatus, are mounted with their scales in a common casing.

Title: Improvements in Valve-mechanism for Internal Combustion Engines of the Revolving-cylinder Type.
Inventor: HARPER WILLIAM
IPC: F02B57/08
Filed: 1919-03-07
Abstract: 124,433. Harper, W. March 7, 1918, [Convention date]. Valves; valvegear.-In a revolving-cylinder engine the exhaust valves 25 are worked from cams in the crank chamber by overhead levers 29, 37, Fig. 2, supported from a casting 32 which bears on the valve seating 26. Initial movement of the exhaust valve is effected by engagement of the lever 29 with the end 42 of the lever 37, and the valve is afterwards opened quickly when the end 44 of lever 29 engages the lever 37 at an intermediate poinL so as to multiply the motion of the actuating cams. To prevent lateral pressure on the valve stem, the motion of the levers is transmitted by means of a block 39 which rests in a circular recess in the lever 37, and has a stem 40 sliding between pins 41 on the lever 29. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the inlet valve and gear shown in Fig. 1, (Cancelled). The inlet valves 12 mounted in the pistons are opened by oscillating cams 23 carried by the connecting rods. The cam 23 engages a lever 22 pivoted on the piston so as to raise the push-rod 18 and compress a spring 20 within the hollow valvestem until the spring pressure overcomes the resistance of the valve-closing spring 17 and opens the valve. The lever 22 multiplies the motion of the cam so that the spring 20 is compressed quickly to open the valve On the power stroke of the piston, the gear compresses the spring 20, but the valve is held to its seat by the pressure in the cylinder. The exhaust valve is of larger diameter than the inlet valve to permit of removal of the latter with its seating through the cylinder head. This subjectmatter does not appear in the Specification as accepted.

Abstract: 439,397. Automatic guns. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST, BRNO, 7, U Lazaretu, Brunn, Czecho Slovakia. Feb. 22, 1935, No. 5764. Convention date, Feb. 22, 1934. [Class 92 (ii)] Relates to firing mechanism for guns which are operated by and synchronized with an external power-driven element such as an aircraft propeller shaft, and consists in providing tensioning means for the percussion spring 16 and releasing means for the sear 11 both of which are operated by a common member 34 actuated during the last part of the closing movement of the breech. The invention is shown applied to a gun in which the barrel 1 moves forwards on discharge the member 34 being in the form of a sliding rod engaged by a projection 5 on the barrel. Fig. 1 shows the position of the parts immediately after firing. The rod 34 is connected firstly by a lever 31 with a sliding spring-pressed box 17 containing the firing spring 16 and secondly by inclined surfaces 15 with the rear end of the pivoted sear 11. When the barrel moves forwardly on discharge, the rod 34, Fig. 3, moves forwardly under the action of the spring 24 which through a projection 22 on the box causes the retraction of the firing pin until it is held by the sear. On the return of the barrel, the rod 34 is engaged by the projection 5 and moved rearwardly to slide the box forwardly, compress the percussion spring, and finally release the sear.

Abstract: 887,068. Transistor multivibrator circuits. GENERAL ELECTRIC CO. Ltd., and PUGSLEY, P. C. Feb. 12, 1960 [Feb. 19, 1959], No. 5777/59. Class 40(6). A multivibrator circuit comprising transistors 1, 2 reciprocally coupled through capacitors 3, 4 is modified by the insertion of a normally non-conducting transistor 13 in the emitter circuit of the transistor 1 so that the circuit normally assumes a stable state with the transistor 2 conducting but will oscillate on the application of a negative control pulse at the terminal 17 to render the transistor 13 conductive. A feedback connection via a diode 19 is provided from the collector of transistor 2 to the base of transistor 13; during the portion of the cycle in which transistor 2 is not conducting a negative potential is fed back to maintain transistor 13 conductive whether or not the control pulse at 17 has terminated. Hence that part of the cycle in which transistor 2 is not conducting is always completed when the pulse at 17 ceases during it. Resistor 24 is provided to produce a sharp leading edge when transistor 2 is switched off; the collector of transistor rapidly assumes a potential determined by that of line 8 and the ratio of resistors 11 and 24, line 7 being set to that potential also. The diode 23 prevents the collector from going more negative than this. Resistor 20 is of small value compared to resistor 21 and applies a small negative bias to the base of transistor 1 during the quiescent state of the circuit.

Abstract: 452,582. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and DITCHAM, W. T., Tudor House, Broomfield Road, Chelmsford. Feb. 25, 1935, No. 5993. [Class 40 (v)] In a carrierwave transmitting system employing a power amplifier following the modulating stage, distortion is avoided by rectifying the modulated carrier derived from circuits preceding and following the power amplifier, combining the rectified voltages in opposition, and applying the resultant voltage as grid bias to the modulating valve in such a way as to compensate the distortion. As shown, a carrier amplifier Vl is connected in series with a valve V2 to the grid of which modulating-voltage is applied through a transformer M. The modulated output in the circuit LC1 is fed to a power amplifier V3 having an output circuit LC2. Coils MA, PA coupled to the circuits LC1, LC2 feed rectifiers D1, D2, the rectified current being smoothed and passed through load resistances R1, R2. These are connected in series opposition in the grid biassing circuit of the valve V2. Any distortion introduced by the valve V3 causes compensating-voltages to be applied to the valve V2. The voltage across the combined resistances R1, R2 may be amplified by a direct-current amplifier before application to the grid circuit of the valve V2, Fig. 2 (not shown). A single rectifier may be fed jointly by the coils MA, PA, Fig. 3 (not shown). Specification 262,820, [Class 40 (v)], is referred to.
