Title: Improvements in machine guns mounted on aircraft
IPC: F41A19/05
Filed: 1920-07-10
Abstract: 148,519. Ago Flugzeugwerke Ges. July 18, 1916, [Convention date]. Machine guns; fire between aircraft propeller blades, controlling and synchronizing.-Consists in effecting the entire operation of the gun by gearing from the propeller shaft, so that the gun is fired always when the propeller blades occupy a definite position, known to the operator, in their plane of rotation. Fig. 1 shows in plan a machine gun b disposed laterally of the propeller shaft. It is not rigidly installed in the aircraft, but is provided with a swivel movement. The gun is actuated from the propeller shaft through a coupling o and a cardan joint d actuating a shaft on the gun, which shaft remains in all positions of the gun parallel to the axis of the gun bore. Fig. 4 shows a modification in which the gun b is mounted on an outrigger d riding loosely on the propeller shaft a, so that it may be swung into any position relatively thereto. The gun is counterweighted at c, and is actuated from the propeller shaft through chain and pinion gearing f, e which transposes the working cycle of the gun in accordance with its position relative to the propeller shaft.

IPC: E01B9/18
Filed: 1953-07-23
Abstract: 736,055. Wood-screws; screw-sockets. DUSSELDORFER EISENHUTTENGES. July 23, 1953 [Aug. 6, 1952], No. 20509/53. Classes 89(1) and 89(2). A permanent-way rail fastening comprises a wooden plug 1 embedded in the sleeper, e.g. of reinforced concrete, and having a cylindrical bore 19 for a screw 3. The threads of the screw are such that the angle which the flank 7 facing the head-end 6 makes with the normal to the axis of the screw is greater than the angle which the flank 8 makes with said normal. The angles lie within the ranges 45 to 55 degrees, and 10 to 25 degrees, respectively and are preferably 55 and 15 degrees. The crest 13 of the thread may be flattened or rounded. The plug may have a slot 18 or diametrically-opposed slots transverse to the longitudinal axis of the sleeper.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M7/08
Filed: 1951-09-03
Abstract: 713,545. Spray carburetters. GENERAL MOTORS CORPORATION. Sept. 3, 1951 [Sept. 23, 1950], No. 20692/51. Class 7(3) A carburetter comprises an accelerator pump having a piston 26 operated as described below by a mixture throttle 6 and a suction operated device is employed to prevent flow of fuel through the discharge passage 35 of the pump, Fig. 2, under the effect of suction when the pump is not being operated. As shown the device comprises a piston 67 working in a cylinder 60 and carrying a pin 70 which co-operates with a non-return valve 62. The pin is normally away from the valve 62 and it can open against the force of a light spring 63 when the pump is operated. If suction is communicated to the cylinder 60 through the pump discharge nozzle 61 the piston is drawn down and the pin 70 holds the valve on its seat so that no matter what the suction in the induction passage may be, fuel cannot be drawn thereby through the nozzle 61 into the mixture passage. The exterior of the piston 67 comprises annular ribs not shown with longitudinal slots in them which permit flow of fuel to the nozzle 61 when the pump is operated. When the throttle is operated at moderate speed the pump is operated through, the spring 27 but if the throttle opening is very rapid an arm 29 moves the piston down and then the spring expands forcing the piston further down. The carburetter is in three castings 1, 2, 3, separated by gaskets which limit heat transfer. The choke valve 7 is manually operated and is closed or partly closed when starting from cold to a position dependent on temperature. Suction when the engine starts to run, can pull the choke valve open to some extent against a spring 10. The choke valve also moves the throttle slightly towards the open position when the choke valve is moved to its fully closed position. Openings 52, 53 admit air to the fuel supply conduit 45. A tube, 54, tends to minimize the formation of vapour bubbles in the idling mixture.

Abstract: 139,545. Rushworth, G. A. W. Dec. 16, 1918. Hand-stamps.-A self-inking turn-over handstamp is fitted with means for locating the impression comprising a transparent index plate lettered or otherwise marked to correspond with the impression and movable, by the movement of the stamp, between a position where it shows exactly where the impression will be made and a position clear thereof. The index plate may be made of celluloid, gelatine, mica, tracing-cloth, fine muslin, &c. In one arrangement, the under plate f, Fig. 1, is carried by arms E pivoted to a clip e engaging the top plate A of the stamp frame, and normally rests between guides f at the base of the frame.

Title: Improvements in and relating to steam turbine plants
Inventor: CALDWELL JOHN
IPC: F01D21/00
Filed: 1957-07-03
Abstract: 884,294. Steam turbine plant. ENGLISH ELECTRIC CO. Ltd. June 27, 1958 [July 3, 1957], No. 21010/57. Class 110 (3). A steam turbine having a dump valve provided between the control valve and the cylinder directly controlled by it, a reheater between the cylinder and the following cylinder of lower pressure and an interceptor valve between the reheater and lower pressure cylinder, has the control of the dump valve co-ordinated with that of the control and interceptor valves so that the dump valve is opened when these valves are closed. High-pressure steam is supplied through pipes P, stop valves S and throttle valves T to the high-pressure turbine cylinder H. The cylinder H discharges through a reheater R to an intermediate pressure cylinder I which exhausts through a divided flow low pressure cylinder L. Interceptor valves N and emergency interceptor valves E are located between the reheater R and the intermediate pressure cylinder I. A dump valve V is arranged in a branch D leading off the pipes P between the throttle valves T and high-pressure cylinder H. Upon a sudden increase of speed, the throttle valves T and interceptor valves N are closed and the dump valve V opened. At a predetermined pressure the valve V is arranged to reseat and so prevent air entering the cylinder H. When the interceptor valves N are closed the flow of steam through the cylinder H is reversed so that it acts as a braking torque on the rotor.

Fresh washing liquid is introduced at the final beck and is passed rearwardly through the becks to be removed from the first beck.  Open width fabric 9, Fig. 1, is immersed successively in baths 1, 2, 3 and 4 in which washing liquid is heated and agitated by steam from pipes 21.  Squeezing rollers 5, 6, 7 are mounted at the delivery side of becks 1, 2, 3 respectively, and squeezing rollers 8A, 8 at the delivery side of beck 4.  Liquid removed by rollers 5 and 6 is collected in trays and allowed to drain away, whilst that removed by rollers 7 and 8 is collected by trays and fed back to becks 1 and 2 and beck 3, respectively.  The squeezing rollers are loaded by springs 18 and/or weights and are driven by a common shaft 15 through worm gearing. According to the Provisional Specification the successive squeezing rollers apply increasing pressure to the cloth as it passes through the apparatus.

Abstract: 948,345. Carding-engines; winding yarns. BRITISH BELTING & ASBESTOS Ltd. June 16, 1960, No. 21179/60. Headings D1J and D1N. In apparatus for controlling the winding of rovings, slubbings or sliver from a carding machine on to a condenser bobbin which is driven by frictional peripheral contact between a revolving drum and the winding (the drum and bobbin axes being parallel) the bobbin spindle ends are carried by slidable members guided to have straight line movement under the control of a variable friction brake. The resistance to movement of the winding and bobbin away from the drum is controllable whereby the tension and winding density of the roving &c. may be varied. As shown, sliding movement of a block 7 (carrying one end of a bobbin spindle 8 in its forward cradle) along a bar 4, in a bracket 2 attached to the machine frame 1, is resisted by a brake pad 15 held in place by U-plate 9 releasably locked by a bar 10. The block may be reversed so that its rearward cradle replaces a worn cradle 8. Movement of bar 10 (limited by a a stop 18) turns a pivot 13 so that an adjustably protruding end of bar 10 bears against a plate 14 thus lifting the pivot and plate 9 and applying pressure to the pad 15 by pressing it between bar 4 and a plate 16 held against a rubber insert 17.
