Filed: 1938-11-09
Abstract: 522,833. Aircraft landing-gear. DOWTY, G. H. Nov. 9, 1938, No. 32576. [Class 4] [Also in Group XXXII] In aircraft alighting gear in which a piston and cylinder shock-absorber is comprised within a lever carrying a spindle for the alighting element, the interior of the piston forms a hollow chamber for compressed air, movement of the piston causing flow of liquid between the chamber and the cylinder. As shown. the lever 5 is pivotally mounted on a cantilever undercarriage member 1 and carries a landing- wheel spindle 7. The lever includes the cylinder 5 within which moves the piston 8, which is connected by a link 17 to the member 1. Liquid is metered, by a valve 11, through ports 10 in the piston. A piston 13 separates the oil in the piston 8 from compressed air in the space 14. An abutment 6A supports the wheel when it is unloaded. The link may be replaced by a construction similar to that described in Specification 517,724. Specifications 473,756, 473,768, 517,370, 517,373, 517,380, 520,995 and 521,219 also are referred to.

Abstract: 893,262. Hydro-pneumatic spring-units. EATON AXLES Ltd. Oct. 8, 1959 [Oct. 14, 1958], No. 32760/58. Class 108(3). In a hydro-pneumatic suspension system for a vehicle, a damping valve 21 controlling the flow of fluid from a ram and cylinder reaction unit 2, 6 to a hydraulic accumulator chamber 22 has its effective orifice varied by the pressure in the accumulator system so that the degree of damping is increased with the vehicle mass. In one example a poppet valve 25 is urged away from its seating 24 by a tension spring 27 and is controllably urged towards the seating by pressure in a chamber 35 formed in a guide spider 26 and connected through a bore 28 to the accumulator chamber. The opposite force of the valve is open to low pressure in the hydraulic reservoir through a pipe 31 and cylinder guideway 29. A high pressure may be applied to the valve through a pipeline 32 to reduce the gap to a minimum, a non-return valve 33 being provided in the passage 28 to prevent the escape of high pressure fluid to the accumulator. The suspension system is described in Specification 893,261. Specification 857,554 also is referred to.

Abstract: 925,413. Generating combustion products under pressure. GARRETT CORPORATION. Sept. 28, 1959 [Sept. 29, 1958], No. 32897/59. Class 51 (1). A combustion apparatus such as for a gas turbine engine is provided with means for causing the combustion gases to flow generally axially through an annular passageway and with means for introducing a liquid coolant into the combustion gases by injecting the coolant radially outwardly from the inner periphery of the annular passageway and with further means for causing the mixture of combustion gases and coolant to flow centripetally towards the axis of the chamber whilst swirling about that axis. The apparatus shown comprises an air-jacketed combustion chamber 1 having an outer casing 28 and an inner flame tube 30, to which air under pressure is supplied through inlet duct 2 and fuel through inlet duct 32. The flame tube has air inlet openings 34 in the wall thereof. The chamber 1 has an end wall 10 having a central opening 11, the wall 10 being secured to the outer casing 28 and the flame tube 30 by means of a ring member 27 and bolts 26; a combustion gasoutlet duct 25 is secured to a flange 23 on the end wall. Air under pressure from the inlet 3 is supplied through branch 4 to a reservoir 5 to pressurize liquid coolant such as wateralcohol contained therein. The coolant passes through ducts 6 and 20 to a distribution chamber 7 disposed within the flame tube at the outlet end thereof. The chamber 7 is formed by a disc member 9 having a cylindrical flange 12 to which is secured a cover-plate 15, the flange 12 being formed with radially-directed orifices 17 through which liquid coolant is ejected into the combustion gases flowing through the annular passage formed between the flange 12 and the flame tube wall 30.

Any particles of the coolant not vaporized are thereby flung outwardly and become vaporized before discharging with the combustion gases through the outlet 11. The air under pressure may be supplied from a storage bottle.

Title: Storing- and counting-circuit with magnetic elements of rectangular hysteresis loop
IPC: H03K23/76
Filed: 1963-08-23
Abstract: 1,016,580. Electronic counters. STANDARD TELEPHONES & CABLES Ltd. Aug. 23, 1963 [Aug. 28, 1962], No. 33473/63. Heading G4A. [Also in Division H3] An electronic counter includes a plurality of serially connected magnetic elements having rectangular hysteresis characteristics and reversible at different current intensities. As described, when a pulse E is received, a bistable transistor pair Tr1, Tr2 is switched so that transistor Tr2 conducts and through an inductance L, which may be a marginal relay, produces a gradually increasing current in the setting windings SE of the magnetic elements K1, K2, K3, K4, which require successively higher switching currents to reverse them. When the element K1 switches, a pulse is generated in the read-out loop LS, which pulse is amplified by a transistor Tr3 and used to switch the bi-stable pair Tr1, Tr2 back to its original state. When a further pulse E is received the transistor Tr2 is again switched to conduction until the next highest element K2 is switched. Thus the elements K1, K2, K3, K4 are switched in sequence. In a modification a reset winding SR is provided; if, for example, the element K3 has just been switched, a back current is passed through diode D and resistor R1, which current is insufficient to switch back the element K3 but is sufficient to switch all lower elements K1, K2; thus the elements are switched in a binary manner. In a further modification the windings SE, SR are duplicated in opposite directions through the elements, and a selection switch is provided to produce a reversible binary counter. In yet a further modification the bi-stable circuit may be biased so that it is mono-stable with transistor Tr2 conducting when it is required to read out the numbers stored in the counter. This causes a high frequency chain of zeroizing pulses to be generated, the number of which is the complement of the number stored. In any embodiment when the counter is full, i.e. all the cores are in the reversed state, and another pulse is received, the transistor Tr2 conducts continuously until the relay L responds to indicate an overflow. The elements may be simple magnetic cores, perforated plates of ferrite, angular tape-wound cores, transfluxors &c.
