Title: Improvements in or relating to pneumatic machine guns
IPC: F41B11/54
Filed: 1934-03-23
Abstract: 433,389. Machine guns. MACIEJEWSKI, K., 32, Polna, Warsaw. March 23, 1934, No. 9213. [Classes 92 (ii) and 119] A pneumatic machine gun firing lead shot is operated both as to discharge and shotfeed by a supply of compressed air at constant pressure admitted through a trigger-controlled passage 7 to a chamber 4 to build up pressure therein to open a valve 10 and discharge a shot through the barrel 1, the pressure also acting to operate a rotary or sliding member 17 for feeding shot to the barrel from a hopper 16. In the example shown, the ball valve 10 is connected by a spring 11 with a piston 9 sliding in a cylinder 3 against the action of a return spring 13. The valve is also loosely connected with the piston by a spring-controlled rod 11<b> which acts to open the valve 10 when a pressure sufficient for discharge has been built up, the spring 11 causing rapid closing of the valve 10 when the pressure falls after discharge thereby causing automatic discharge by puffs of air. The piston is connected by a rod to a ratchet device on the member 17 for feeding the shots one by one to the barrel and for agitating the shots in the hopper 16. The gun shown is adapted to form an attachment to the stripped casing of an ordinary machine gun for the discharge of lead shot for practice purposes.

Title: Improvements in Trusses.
Inventor: BEST WILLIAM NEWTON
IPC: A61F5/30
Filed: 1917-06-28
Abstract: 107,592. Best, W. N. June 28, 1916, [Convention date]. Trusses.-A truss pad comprises two cup-shaped telescoping members 10, 11 having pin and slot connexions 21, 22 so as to have limited sliding and rocking movement, and normally pressed apart by springs 16 held in place by projecting studs 15. A band 23 of cloth, rubber, &c., connects the parts 10, 11 so as to seat the pad and prevent pinching of the body between the two parts. The member 11 is fitted with transverse bars 14 forming a guide for the truss belt. In modifications, the springs 16 are held in place by annular flanges in place of the studs or may be replaced by leaf springs. The pads are formed of hard rubber or metal suitably covered or coated.

Abstract: 552,884. Aircraft undercarriages. PHILLIPS & POWIS AIRCRAFT, Ltd., BOURNON, R. N., and FENNER, R. J. July 23, 1941, No. 9333. [Class 4] An undercarriage leg 5 pivoted to the aircraft about a pivot 4 and braced in its extended position by a breakable strut 14, 15 is retracted by movement in an anticlockwise direction of an arm 19 connected by a rod 20 to a bell crank lever 21 pivoted on an extension 26 of the strut member 15, initial movement of the arm 19 causing the lever 21 to unlock the joint and afterwards rotating the strut member 15 away from the leg until it reaches the position shown in chain lines. The lever 21 has a pin 22 movable in a cam slot 23 in a plate 24 on the strut member 14 and in a slot in the extension 26. When the pin reaches the end of the latter slot it is clear of the slot 23 and movement of the strut members 14, 15 causes the pin 22 to move along a cam edge 28 in the plate 24 until it reaches the position shown in Fig. 3. In this position the extended pivot pin 29 at the end of the rod 20 engages a spring catch 30 acting as an up-lock. To lower the leg, the rotation of the arm 19 is reversed, initial movement causing the pin 29 to leave the catch 30 after which the pin 22 during the relative movement of the strut members 14, 15 moves along a cam edge 35 in the plate 24 until it reaches the shoulder of the slot 23 after which the lever 21 moves to lock the strut in its extended position. The wheel 13 is mounted on a trailing lever 9 pivoted to a bracket 7 on the leg 5 which houses a shock absorber connected by a rod to the lever 9.

Abstract: 493,361. Discharge lamps. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) April 5, 1937, Nos. 9636/37, 6263/38, and 6264/38. [Class 39 (i)] A discharge lamp containing either neon or neon and mercury vapour is arranged to have a nearly constant or slightly positive voltagecurrent characteristic. For this purpose the gas pressure, apart from mercury is from 4 to 8 mm., and the current density is not greater than 30 mA (sq. cm. of cross section of envelope) ; also to the neon are added argon and krypton or xenon, so that if the percentage of argon is y and krypton or xenon x, 2x+y lies between 0À2 and À05 if no mercury is present, and between 0À2 and 2 if mercury is present, the vapour pressure of the mercury not greatly exceeding À001 mm. Furthermore, if thermionic electrodes are employed the tube must be so long that the total characteristic is substantially that of the positive column. Preferably, however, the electrodes are hollow metal cylinders. To keep the mercury vapour pressure at the desired level the electrodes may be formed as nearlv closed canisters containing mercury. The canister may be polished highly on its outer surface, or covered with heat insulating material or a vacuum jacket, the 'discharge entering the mouth of the canister. Specific examples are given and Specifications 227,832, [Class 39 (i)], 395,851, 405,499, 418,027, 431,382, and 476,240, are referred to.

Filed: 1932-04-05
Abstract: 397,590. Moistening air. LINDSAY, T., Windsor House, Victoria Street, London. April 5, 1932, No. 9690. [Class 55 (ii).] A differential thermostat comprising a dry temperature sensitive member 1 and a similar member 2 covered with moistened fabric 5, combined with two hydraulic regulators of leak port type (such as described in Specification 116,074*, [Class 69 (ii), Hydraulic presses &c.]) has a lever 22 carrying the checking member 23, 24 of each regulator and is acted on by member 1 whilst member 2 acts on a lever 27 carrying the aperture 26 for the escape of non- compressible fluid of one of the regulators. Whilst the regulator comprising jet 26 operates to maintain a constant difference between dry and wet bulb temperatures, the regulator comprising jet 25 maintains a constant temperature. On a rise in temperature tube 1 acts on lever 22 to cause checking member 24 to move away from aperture 26 and so reduce the pressure of the air, water, oil or other fluid in conduit 41. A diaphragm valve which may be of the type described in Specifications 218,370 and 232,304, [both in Class 135, Valves &c.], is thus operated to increase the water supply to the humidifier. Jet 25 is however suppressed by the member 23 and the pressure increase in conduit 40 is caused to throttle a valve supplying heating fluid to the heater for the humidified air and so reduce the temperature to its original level. Specification 363,630, [Group XIII], is referred to.
