Title: Improvements in or relating to gear-driven pumps
IPC: F04C14/18
Filed: 1934-02-16
Abstract: 421,868. Gear-wheel pumps. EGERSDORFER, F., 5, Goethepark, Charlottenburg, Berlin. Feb. 16, 1934, No. 5160. [Class 110 (ii)] A gear pump for supplying fuel to an internal-combustion engine is provided with means for varying the supply. Gears 3, 3<1>, Fig. 1, are each placed between two sleeves 4, 4<1> of the same diameter as the gears. In this construction the pump delivery is varied by sliding the sleeves 4<1> and gear 3<1> axially to decrease the width of meshing of the teeth. Grooves are provided in two diagonally-opposite sleeves 4, 4<1>, to permit this sliding action. The engine suction acts through a pipe 7 upon a regulating piston 6<1>, and actuates the sleeves 41 through a lever 8<1>. The sliding may be effected by rodding connected with a throttle valve in the engine suction piping, through the medium of an accelerator. In a second arrangement, Fig. 5, the driven gear does not move axially. A rotary slide valve 12 is driven by a shaft 15 and controls the distribution of the delivery to various engine feed lines 18. A piston 16 is subjected to the delivery pressure, oil passing through a duct 17 to a bore 20 leading to an annular groove 21. The piston 16 is rotated by a handle 23 or automatically to regulate the quantity of fuel passing, the duct 17 being slot shaped so that when the slot is turned horizontally, more fuel passes to the bore 20, than when the slot is vertical. The handle 23 may be coupled to a vacuum regulator or to an accelerator. Fig. 10 shows a further arrangement in which a rotary slide valve 29 has a groove 31 which co-operates with a port 32 in each delivery line 38. The injection time is diminished according to the axial displacement of the valve 29. An accumulator may be provided on the pump delivery side to keep the atomizer pressure constant when the engine speed varies. The accumulator may consist of a spring-loaded diaphragm, or of a piston.

Patent GB-921013-A (GB)
Title: Aircraft
Inventor: DAVIDSON IVOR MACAULAY
IPC: B64C23/00
Filed: 1959-02-17
Abstract: 921,013. Aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Feb. 3, 1960 [Feb. 17, 1959], No. 5457/59. Class 4. An aircraft is powered by a plurality of gas turbine jet propulsion engines of the by-pass type having their turbines connected to discharge their turbine exhaust gas streams clear of the wings of the aircraft through individual rearwardly directed propulsion nozzles, and their by-pass compressors connected to supply at least a part of their by-pass air streams through non-return valves to a common duct, wherein the common duct is connected to supply air to further nozzles arranged to discharge the air as long thin streams extending along the span of the wings and means are provided for reducing the discharge area available for the discharge of the by-pass air streams relative to the discharge area available for the discharge of the turbine exhaust gas streams. The aircraft comprises a fuselage 1, wings 2, tail unit 3, 4 and engines 6 located at the rear end of the fuselage. Each engine is of the two spool by-pass type, part of the by-pass air being supplied to a duct 24 through a non-return valve, (not shown), into a common duct 25 which extends through the fuselage to branch ducts 27 in the wings. These ducts 27 are connected through branch pipes 28 to long shallow rearwardly directed jet nozzles 29 extending along the span of the wing above and immediately forward of narrow chord trailing edge flaps 5 which direct the gases issuing from nozzles 29 to act as jet flaps. The duct 25 has a further connection with a rearwardly directed branch 31 terminating in an auxiliary nozzle 32 which may be closed by flaps (not shown). About a quarter to a third of the propulsive effort of the engines goes. into the air stream supplied to the jet flap nozzles 29 and auxiliary nozzle 32. Also, the discharge area afforded by nozzles 29 and 32 is matched to operation of the four engines at the design by-pass ratio, while the discharge area of nozzles 29 alone is matched to operation of three engines only at the design by-pass ratio. Under normal operating conditions nozzle 32 is fully open, but for take-off it is closed thereby changing the by-pass ratio to increase the mass flow through the high-pressure combustion system of each engine. Should an engine fail on take-off the inherent flexibility of the engines will result in an immediate automatic re-adjustment of their by-pass ratios since the total nozzle area then available is matched to three engines only. A further embodiment is described for a canard type aircraft having a main wing of elliptical cross section with rounded trailing edge in which the jet-flap arrangement previously described is applied to the fore-plane only and further branch ducts are taken from the main duct 25 to feed slots adjacent the wing trailing edge to promote circulation in the manner described in Specification 883,865. Specifications 787,011, 787,012, 787,013, 787,014, 787,015, 790,193, 790,194, 790,298, 823,591, 823,592, 823,593, 829,753 and 866,608 also are referred to.

Abstract: 431,589. Recording-apparatus; echosounding apparatus. McGEACHY, J. A., and WOOD, A. B., Admiralty Research Laboratory, Teddington, Middlesex, and DRYSDALE, C. V., Admiralty, London. Feb. 20, 1934, No. 5572. [Class 106 (iv)] [See also Group XXXVIII] In a recorder in which the marking member is reciprocated across the record surface, the marking member is mounted on a carriage which moves along two parallel screws and has a device engaging each screw alternately, the change of engagement being made at the end of each half cycle of reciprocation, one screw thus driving the carriage in one direction and the other in the opposite direction. The screws may be of the same hand and rotating in opposite directions, or of opposite hands and rotating in the same direction. The invention may be used in echo-sounding apparatus. The carriage 2 supports the marker 1 which is moved electromagnetically to press a tape 13 on to the record surface. The carriage 2 has a slidable pin 5 which engages one screw 3 when the carriage is moving in one direction and the other screw 4 when moving in the opposite direction. The change of engagement is caused by the end of the screw thread pushing the pin through the carriage. The carriage may close contacts 6A, 6B when moving from left to right but not when moving in the opposite direction, since the foot 6E which is engaged by the carriage is pivoted. The contacts may be placed in any one of several holes in the bar 8, and may be turned round so that they are closed by the carriage in the opposite direction of travel. In an electrochemical recorder, the marker 1, Fig. 5, is removed from the record during the return of the carriage, this being effected by the rocking of a lever 16 by a fixed abutment. The lever is held in its two positions by a spring 17 and stops 19, 20. Specification 375,375, [Group XXXVIII], is referred to.

Filed: 1926-02-27
Abstract: 266,903. Wild & Co., Ltd., M. B., and Wild, M. B. Feb. 27, 1926. Stopping automatically at end of run; emergency power cut-off gears. - The stop gear is brought into action by means which are actuated by a governor in the case of overspeed and by cam and roller mechanism in the case of an overwind. A lever e carrying a roller d is attached at one end to the governor sleeve f and at the other end supports a rod g having a roller h at its lower end. The roller d rests on a face cam c which is rotated on the governor spindle a through worm gearing k by the winding mechanism. The roller h rests on one end of a lever i which is pivoted to a lever and carries a roller j. The lever l in the position shown engages the lever m of the stop gear and prevents its actuation. An eccentric or cam b is mounted on the spindle a just above the roller j. The shape of the cam c is such that if the speed is normal, the rise and fall of the roller d will correspond with the ordinary acceleration and retardation and there will be no vertical movement of the rod g. If the speed becomes excessive, the governor sleeve will rise in advance of the working face of the cam, and the rod g will be depressed, thereby tilting the lever i and bringing the roller j into contact with the eccentric b. The lever i is thus moved endwise to rock the lever l and release the stop mechanism. At the end of the wind, the roller d falls into a recess in the cam below the normal working face, thus allowing the rod g to drop, and the stop mechanism to be actuated as before. The roller d is restored to normal position by a vertically-movable handactuated slide n which engages the lever e and is provided with a spring pawl o. A lug p on the periphery of the cam engages the pawl o and maintains the roller d at the required height until the cam has been rotated sufficiently to be in position to support it.
