Title: Improvements in vehicle brakes
IPC: F16D57/06
Filed: 1949-03-11
Abstract: 678,510. Hydraulic wheel brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. March 3, 1950 [March 11, 1949], No. 6658/49. Class 103 (i). A wheel brake, particularly for light aircraft, such as helicopters, comprises diametrically opposed pairs of cylinders and pistons 9, 10 which are integral and rotate with the wheel hub 1. The pistons 10 are caused to reciprocate, when the wheel rotates, by the action of a hexagonal member 12 slidable upon a guide member 14, which is journalled on a fixed shaft 13, eccentrically secured to the non-rotatable wheel axle. The closed ends of adjacent cylinders 7, 9, which are filled with liquid, preferably oil, are connected by passages 19, the flow through which is controlled by values 22, Fig. 3. When the wheel rotates, the member 12 is caused to reciprocate on a line perpendicular to the axes of the cylinders 9 and by pressure on the inclined faces 11, drives in first one and then the other of adjacent pistons 10 so that the liquid is forced from one cylinder 7 to the other 9. The degree of braking is then controlled by the action of a push-pull rod 26, passing down the centre of the wheel axle and connected to a brake control lever, the rod 26 having a rack 25 at its end which engages pinions 24 that rotate frusto-conical cocks 22 in the passage between the cylinders. A similar brake having two only diametricallyopposed cylinders is also described.

Title: Improvements in electrical connectors embodying switches
IPC: H01H13/08
Filed: 1930-12-22
Abstract: 375,328. Plug-couplings. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. Dec. 22, 1930, No. 7345/32. Divided on 374,418, [Group XXXVII]. [Class 38 (i).] A combined switch and supply lead connector for an electric iron has switch operating members, one in the form of an arm adapted to overlie the handle of the iron and to be actuated by the pressure of the operator's hand, and another extending rearward of the iron to be held selectively in operative or inoperative position by the pressure of the supporting surface when the iron is stood on end. A metal diaphragm strip 9 is held by metal plates 10, 11 situated in the sides of a recess in the connector casing 1, and carries a resilient contact strip 16 attached to a metal bush 12 through which freely passes a pin 3 working in holes in the insulating casing 1. A hollow cover 30 is pivoted at one end to a pair of links 38 attached to the pin 13, and at the other end to a pair of arms 32 extending from the front of the connector, so that when the latter is in position, the hollow cover overlies the handle of the iron. Depression of the member 30 against a spiral spring 36 causes the links 38 to bear on top of the diaphragm and to depress the contact member 16 into engagement with a contact plate 17, closing the circuit from the lead 6 to the connector socket 3. When the cover 30 is released, the spring 36, in expanding, first compresses a spiral spring 26 placed between the bush 12 and a boss on the lower end of the pin 13, and subsequently raises the bush 12 and contact arm 16 until the diaphragm has reached its dead-centre position, when the spring 26 expands and rapidly raises the contact member 16 out of engagement with the contact plate 17. Pivoted to the back of the links 38 and extending through a hole 41 in the cover is a key 43 which is adapted to bear against the supporting surface when the iron is stood on end. With the key 43 positioned as shown in chain-lines, the edge of the opening 41 bearing against the shaped surface of the key causes the links 38 to be depressed so as to close the circuit. When positioned as shown in full lines, the key 43 holds the links 38 in inoperative position. Specification 340,307, [Group XXXVII], is referred to.

Title: Self priming liquid pumping system
Inventor: JARRETT MICHAEL PETER
IPC: F04D9/06
Filed: 1968-02-15
Abstract: 1,260,833. Centrifugal pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. April 16, 1969 [Feb.15, 1968], No.7367/68. Heading F1C. In a self-priming pumping arrangement, e.g. for the fuel system of a helicopter, comprising a centrifugal pump 10 arranged to draw liquid from a low level tank 13 through piping 12 and a highlevel reservoir 11, the volume of the latter is greater than the volume of the piping 12 by an amount dependent on the vapour pressure and on the volume change in the piping during the most adverse conditions. Thus, during priming, the liquid in the reservoir is always sufficient to cause the pump to initiate liquid flow from the tank to the reservoir. An injector 14, powered by the pump discharge, withdraws vapour from the reservoir.

Title: Improvements in pneumatic tyres
IPC: B60C11/14
Filed: 1941-06-11
Abstract: 549,904. Rubber compositions. HENLEY'S TYRE & RUBBER CO., Ltd., and STANLEY, H. T. June 11, 1941, No. 7373. [Class 70] [Also in Group XXXIV] An outer-cover is formed by mixing lumps of hard and soft unvulcanized rubber intimately, forming to shape, and vulcanizing the shaped product. The divisions between the different kinds of rubber may be sharp as illustrated in Fig. 1, the harder rubber being shown by the grey patches, or may be gradual passing through zones of intermediate qualities, as shown in Fig. 2. The hard rubber is caused to predominate in the tread portion and the soft rubber in the sides of the tyre. The cover may be formed from stips of hard and soft rubber from both of which portions are punched out, these portions not registering when the strips are superposed, so that when rolled together under pressure a composite body without holes is formed. The different rubbers may be mixed in a machine and extruded therefrom to form a cover which is subsequently vulcanized.

Title: Improvements in or relating to engine starter gearing
IPC: F02N15/06
Filed: 1952-03-21
Abstract: 710,538. Turning-gear. BENDIX AVIATION CORPORATION. March 21, 1952 [March 23, 1951], No. 7393/52. Class 7(5) In an engine starter drive having a barrel 11, surrounding both a radial flange member 5 that is connected to the power shaft 1 and a driving clutch member 7, and having means such as slots 10 for preventing relative rotation between the members, the barrel enclosing a nut 18 both slidably journalled in the barrel 11 and threaded on a shaft 16 connected to the pinion 14, the clutch member 7 and the nut 18 are provided with interengaging clutch teeth 8 and 23, respectively, whilst spring means, for example discs 27, are interposed between the flange and driving clutch member in such a manner that the clutch permits rotation of the pinion after the latter has been disconected from the engine, and is adapted to act as an overload slip-clutch; a light mesh enforcing spring 12 may also be located in parallel with the spring discs 27 and a ring 21 in the barrel .limits the longitudinal movement of the nut. Rotation of the shaft 1 is transmitted through barrel 11 and clutch member 7 to the nut 18 so that the pinion and screw shaft 16 are traversed rightwardly until the pinion 14 meshes with the engine whereupon its movement is arrested by the shaft 16 abutting barrel flange 19, the nut 18 and clutch member 7 then being moved backward by the screw jack action of the nut and screw shaft and compressing spring 12 until clutch member 7 engages spring discs 27; further backward motion is resisted by the springs so causing the torque to build up and enabling the pinion to rotate the engine. The torque is limited by engagement of the nut 18 with the ring 21 which arrests backward movement of the nut so that increasing torque wedges apart the teeth 8, 23; if a predetermined torque is exceeded the clutch teeth will ratchet over each other due to further compression of springs 27. When the engine starts the pinion 14 is returned to the normal position with the aid of an anti-drift spring 24 so permitting the clutch member 7 to be returned by spring 12; the pinion momentum is dissipated by overrunning of teeth 8 and 23. If tooth abutment should occur the springs 12 and 27 are compressed by the nut 18 until sufficient torque has been built up to effect indexing whereupon the spring 12 expands and completes the meshing operation.

Title: Adjustable eccentric for sewing machines
IPC: D05B73/00
Filed: 1935-03-11
Abstract: 435,303. Sewing-machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. March 11, 1935, No. 7494. Convention date, July 17, 1934. [Class 112] [See also Group XXVI] A variable throw eccentric, particularly for use in the feed mechanism of a sewing-machine, is secured to its shaft with provision for crosswise adjustment by a cam rotatably mounted on the shaft and engaging a projection on the face of the eccentric, relative movement of the cam and eccentric being normally prevented by a spring- pressed, manually operable detent on the cam which engages an internal arcuate rack on the eccentric, the rack having a centre of curvature noncoincident with the centre of curvature of the periphery of the eccentric. The invention is described as applied to a lower four motion type of dog feed, a visible index on the eccentric indicating the length of stitch. The eccentric 35 has an enlarged bore 36 and is fitted with a flange 37 having two radial slots 38 through which pass two studs 39 screwed into a belt pulley 26 on a driving-shaft 5. The studs 39 also pass through concentric slots 42 in a plate 41, Fig. 6, having a cam slot 46 engaging a roller 45 on a pin 44 on the eccentric. Spring washers 43 prevent axial movement of the eccentric and cam plate. The cam plate 41 has radial bore 55 for receiving the shank 56 and spring 60 of a detent 57 which engages a rack 59 formed in a recess 58 in the eccentric. To effect adjustment, a lever 49, Fig. 2, is moved to press its hooked end 48 into a notch 47 formed in the plate 41 at the end of the bore 55 so as to hold the plate against rotation and also move the detent 57 out of engagement with the rack 59. Rotation of the shaft 5 then causes the cam slot 46 to shift the eccentric radially. Index numbers are marked on the edge of the flange 37. Fig. 8 shows a modification in which an eccentric 61 has projections 65 engaging a diametral groove 66 in a disc 67 secured to the shaft, the opposite face of the eccentric having a roller 69 and arcuate rack co-operating with a cam plate, similar to the cam plate 41 and held in position axially by a collar 64.

Abstract: 776,143. Winding wire &c. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 15, 1954 [March 18, 1953], No. 7509/53. Class 120 (2). [Also in Groups XXXV and XL (b)] A machine for winding delay lines having distributed capacitance and inductance is designed to produce a repeated group of turns a, b, c, d on a mandrel 10. Each group is slightly displaced from the preceding group so that neighbouring groups overlap to a large extent. To this end, the mandrel 10 is caused to oscillate axially by means of a cam 21 driven by gears having a double reduction ratio of 4:1 x 28 : 24. The 28: 24 factor provides for a progression of the crossover point x of turns b, d along a helical path y. The wire guide 27 is traversed by means of a lead screw 28.

Filed: 1918-05-04
Abstract: 124,318. Rulkens, W. J. May 4, 1918. S p e e d indicators actuated by accelerometers.-Relates to indicators of the type in which the accelerations are integrated. The horizontal speed is indicated by a pointer actuated by a roller on an acceleration pendulum, the roller being in frictional contact with a clock-driven roller which is also displaced, in a contrary direction,.by the acceleration of the aircraft. The roller 5 actuating the pointer 11 is carried by a bar 3, which is pivoted on an horizontal axis 1 and is over-weighted at 15 but supported by springs 14 attached to arms 13 on a second member. This member, also pivoted on the axis 1, carries a roller 4 which is driven by clock-work 6 and bears against the roller 5. Relative displacement of the rollers produces a driving component on the roller 5, the total rotation of which is a measure of the speed. Both rollers may be shaped as shown, so as to increase the movement of the pointer. As the apparatus indicates the actual speed only when the aircraft is flying horizontally, an attachment is provided for obtaining a true speed reading when flying at an incline. It consists of three bars, one secured at rightangles to the line of flight, a second bar hanging freely, and the third slidable along the first and at right-angles to it. The third bar being set on the first bar to the indicated horizontal speed, its intersection with the second bar will indicate the true speed.

Abstract: 701,955. Electric indicating systems. PHILLIPS PETROLEUM CO. March 25, 1952 [April 9, 1951], No. 7631/52. Class 40 (1). In a device for detecting the production of ions by e.g. a flame or a chemical reaction, the charged particles resulting from the reaction impinge on an electrical noise resistance of high value to produce random noise voltages therein which are amplified, filtered, and rectified to produce an indicating voltage representing the ionic concentration. Fig. 1 shows a reaction chamber 10 for e.g. the 'high temperature combination of chlorine and benzene entering through valved conduits 11, 12 to form chlorobenzene which is withdrawn through valved conduit 13. A high value electrical noise resistance element 16 of e.g. ceramic material is insulatedly sealed through the chamber walls, and connected across the input of a wide band low noise high gain alternating current amplifier 23, which energises a capacitanceresistance high pass filter 24, 25, followed by a half wave rectifier 26 developing unidirectional output voltage across the averaging load resistance 27 and capacitance 28 which energises a D.C. amplifier 30 feeding a D.C. recorder 31. Ions produced by the reaction bombard the resistance element to produce random noise voltages therein, which after rectification produce a recorded indication of the ionic concentration. and of the reaction activity. Fig. 2 shows a flame detector wherein the ions emitted by the flame impinge on a resistance element in the form of a probe comprising a metal casing 48 enclosing an electrode 49 embedded in a ceramic tip 40. The output is amplified as before and applied to an A.C. voltmeter 46 indicating the ionic concentration, or to a known warning device. The detecting resistance element may comprise merely the gas in a gap between two electrodes on which a flame plays, and across which the ionic noise signal appears, Fig. 3 (not shown). A metallic resistor may be used for the detection element, which should have as large a surface area as possible.
