Title: Improvements in valves, particularly for hydraulic brake systems
IPC: B60T11/16
Filed: 1931-09-17
Abstract: 384,724. Fluid - pressure brakes; valves; stuffing- boxes. BARKER, G. G., 14, High Holborn, London.-(Hydraulic Brake Co. ; 2843, East Grand Boulevard, Detroit, Michigan, U.S.A.) Sept. 17, 1931, No. 26061. [Class 103 (i).] A valve device, particularly for retaining a pressure above atmospheric in the brake cylinders of a hydraulic brake system when the brakes are released, to prevent inlet of air to the system comprises a rigid cup-shaped member 44 with an upturned edge 46, normally seated by a spring 48 on the end of the master cylinder 3 to close the passage 56 leading to the brake cylinders. A member 55 of rubber or other resilient material secured within the member 44 by a bead 52 normally closes apertures 54 in the member 44. When the master piston 6 is operated, as by a pedal, to apply the brakes the liquid presses back the member 55 and flows through the apertures 54 to the passage 56 but the liquid can only return to the cylinder 3 during release of the brakes as long as the pressure in the passage 56 is sufficient to unseat the member 44 against the action of the spring 48. In the system shown, the reservoir connected at 36 communicates through passages 34, 33 with the rear of the piston 6 and the chamber formed by a rubber &c. boot 22 secured at one end to the cylinder 3 and at the other to the piston-rod 16 by a nut 20. A second boot 28 for protecting the boot 22 is secured at one end by a collar 31 on the nut 20 and at the other by the ring 25 and collar 27 thereon, the ring 25 serving also to fix the one end of the boot 22. A port 62 connects the reservoir to the forward part of the cylinder 3 in the release position of the piston 6. During the release movement of the piston effected by the spring 48, the pressure in the forward part of the cylinder 3 tends to fall, causing liquid to flow into it from behind the piston through the passages 37 and past the packing-cup 8. The connection of the operating pedal 59 with the piston comprises a rod 58 slidable in the pistonrod 16.

Title: Improvements in or relating to relaying telegraph circuits
IPC: H03K17/66
Filed: 1958-08-13
Abstract: 845,060. Code telegraphy. TELEFUNKEN G.m.b.H. Aug. 13, 1958 [Aug. 16, 1957], No. 26076/58. Class 40(3). [Also in Group XL(c)]. A circuit for relaying single current or double current telegraph signals comprises an input bridge having two adjacent resistance arms of equal value and two further adjacent arms each comprising the base emitter path of two transistors in series, the emitter collector path of the second of the two transistors in each arm forming with two further resistors an output bridge with output terminals connected to the collector electrodes, input signals being applied to the bridge so as to render the transistors in one or other arm of the input bridge non-conductive. In Fig. 4 the circuit takes the form of a push-pull amplifier comprising an emitter follower stage Tr1, Tr2 feeding a common emitter output stage Tr3, Tr4, all the transistors being normally conductive. Double current telegraph signals applied to the input terminals 1, 2 render either one side or the other side of the amplifier non-conductive producing corresponding output potentials at terminals 4 and 5. If one of the input terminals 1, 2 is connected to a suitable reference potential single current telegraph signals can be applied between the other terminal and terminal 3. Zener diodes D1 and D2 limit the potential applied to the collectors more particularly when the circuit feeds an inductive load. Adjustment of the bias resistor R3 varies the delay in switching off the transistors.

Abstract: 898,195. Rocket motor casings. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 1, 1959 [Aug. 15, 1958], No. 26387/58. Drawings to Specification. Class 9(2). A tubular pressure vessel, e.g. a rocket motor casing, is made by applying a parting agent to a mandrel, followed by a layer or layers of thermoplastic or cured or curable elastomeric material adapted to provide a hydraulic seal, and then applying successive layers of helically wound strip metal and bonding material to form a structure in which the edges of the strip metal abut in each layer and the edges are displaced in successive layers; the layers are bonded together, e.g. by internally heating the mandrel, and the tubular structure is removed. The parting agent, e.g. paper sheet, prevents the thermoplastic or elastomeric material from sticking to the mandrel. Epoxy resins, e.g. the condensation product of epichlorhydrin and bisphenol, are suitable bonding materials for steel strip. Polyethylene or polyvinyl chloride may be used as the hydraulic sealing material, which may also act as thermal insulation. Further thermal insulation may be added after removal from the mandrel. In order to attach an end portion to the tube, an extruded rubber or thermoplastic element is bonded to the tube and the end portion. Specification 898,194 is referred to.

Title: Improvements in wheels for resilient tyres for road vehicles
IPC: B60B25/02
Filed: 1922-10-06
Abstract: 204,219. Smith, R. T. Oct. 6, 1922. Detachable - rim attachments to wheels; tyre attachments to rim.-A detachable rim A is formed of segments a, a<1>, a<2> which can be separately placed in position on the tyre. The inner surfaces a<3> of the segments are inclined to correspond with an inclined surface b of the body part B of the wheel so that as the segments move up the incline they are forced radially outwards against the pressure of the tyre. A lug c is riveted to the centre of each rim segment, and pieces c<1> bear on lugs c<2> at the segment ends so that by screwing up nuts d on screwbolts D passing through the part B and the lugs c and pieces c<1>, the segments are forced up the inclines b. To prevent creeping, a projection c<3> on each lug c fits a slot b<1> in the body B of the wheel. In alternative constructions each segment has a flanged piece riveted to it, the inner surface of the flanged piece fitting the inclined part b on the body of the wheel. Screw bolts pass through the body part and the flanged pieces so that by screwing up the nuts d the segments are forced up the incline. In wooden spoke wheels a metal ring is secured to the wooden periphery of the wheel and inclined to fit against the flanged pieces on rhe rim. In rims carrying solid tyres, each segment a has a shoulder forming an abutment for a ring which, when the nuts d are tightened up, forces the rim A and the tyre on to the body part.
