Title: Improvements relating to compressed fluid braking apparatus
IPC: B60T15/30
Filed: 1957-09-25
Abstract: 846,314. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and WASHBOURN, J. Sept. 25, 1958 [Sept. 25, 1957], No. 30088/57. Class 103 (1). In a direct release triple valve device for compressed fluid braking apparatus, particularly for railway vehicles, of the kind including an application valve 17 controlling the communication between a source of compressed fluid afforded by an auxiliary reservoir and a brake cylinder, not shown, the valve 17 being operable by a diaphragm 13 subject respectively on its opposite sides to auxiliary reservoir pressure in chamber 15 and the pressure in the normally charged brake pipe in chamber 14, the effective area of the diaphragm 13 exposed to brake pipe pressure is greater, at least in the normal undeflected position of the diaphragm corresponding to closure of the application valve, then the effective area exposed to the auxiliary reservoir pressure. This condition is inherent in the construction shown, as the effective area exposed to chamber 14 is substantially undiminished by the central spindle member whereas the effective area of the lower face of the diaphragm 13 is diminished by the cross-sectional area of the stems 26 and 27, which pass sealingly through bores in the respective valve bodies 28 and 29. The unbalance of effective area above and below the diaphragm 13 provides a biasing force which is sufficient to ensure that the auxiliary reservoir pressure must exceed the brake pipe pressure by more than a certain amount before the diaphragm will be moved upwardly, thus providing a resistance to movement by jolting or small fluctuations of the controlling pressure. Specification 846,313 is referred to.

Abstract: 1,069,076. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 18, 1964 [July 31, 1963], No. 30449/63. Heading B7K. An air cushion vehicle in which the cushion apace is bounded for at least part of its periphery by a deflectable wall structure comprises a flexible diaphragm extending downwardly from the bottom surface of the vehicle body to contain said cushion and strut means disposed outboard of the diaphragm extending downwardly between said bottom surface and the lower edge of the diaphragm, at least the lower part of the strut means being movable relative to the vehicle body, whereby, on inward movement of the strut means, the diaphragm rolls outwardly over the inner surface of the strut means so that cushion pressure acting on the diaphragm resists said movement. The cushion space 4 is supplied with pressure air by fans 3 and the cushion is contained by a flexible diaphragm 7 which is held extended by a plurality of struts 8 pivotally attached to the vehicle body 1 and to the lower edge 10 of the skirt. Deflectors may be provided to cause the air from the fans 3 to flow down the inside face of diaphragm 7 and emerge as a peripheral curtain. In other arrangements the struts 8 are formed by inflatable tubes which may be sealed at their lower ends or open for the outflow of curtain-forming jets. Individual tubes may be connected by diaphragms in order that the cavity formed between the tubes and the skirt 7 may be pressurized. One or more flexible ties may be attached to the diaphragm 7 to limit its. deflection under cushion pressure. Intermediate walls having any of the constructions described may be provided longitudinally or transversely of the cushion space. A rear wall constructed in the manner described in Specification 1,043,351 may be provided. Reference has been directed by the Comptroller to Specification 935,825.

Title: Improvements in or relating to Ball Valves and Parallel Plate Valves
Inventor: DAVISON GEORGE ROBERT
IPC: F16K3/20
Filed: 1966-10-14
Abstract: 1,181,228. Valves. BRYAN DONKIN CO. Ltd. 11 Oct., 1967 [14 Oct., 1966; 3 July, 1967], Nos. 46121/66 and 30557/66. Heading F2V. In a ball or sliding plate valve, enhanced sealing without an increase in wear of the sealing rings is effected by an arrangement whereby fluid pressure is introduced to annular chambers formed between the sealing rings, which are movable, and the valve body subsequent to the valve being closed, and is released from the same prior to the valve being opened, the arrangement being operable by the valve actuating system and incorporating a lost-motion coupling. In the case of a ball valve, opening of the ball valve 14 is initiated by rotation of a handle 246 and hence of a pinion 276, the pinion meshing with a gear segment 274 which has formed integrally therewith a cam surface (298, Fig. 2, not shown), the surface together with a follower (300) serving to actuate the pressurizing arrangement 242. The gear segment is connected through a lost-motion coupling 244 to the valve spindle 18. The follower is mounted on a piston biased against the cam by a spring 306, such that as the cam follower rides down the surface, pressure within chamber 304, and hence within the chambers formed between seat rings 32 and valve body 10, is reduced. Such reduction permits leftward movement of a differential piston 250, the larger face 256 of which is acted upon by fluid pressure present in chamber 258, which pressure is derived from the inlet 12, and by a further piston 266 acted upon by pressure derived from the outlet. The interconnection between pistons 256 and 266 carries a pointer 310 which indicates the state of the valve. As the pressure within chamber 304 is being reduced, a pin 284, pivotally connected to a link 280 which is similarly connected to a lever 278 fixed to the spindle 18, moves inwardly within radial slots 290 formed in the gear segment 274, such inward motion being due to a further cam 274 riding on a cam surface (294, Fig. 2) formed on the housing 296. Upon the pin reaching a stop 288, at which stage pressure within chamber 304 has been fully reduced, further rotation of the gear causes the lever 278 and hence the spindle to be rotated to effect opening of the valve. A similar actuating arrangement, incorporating a lost-motion coupling, may be provided for the sliding plate valve, this, however, being modified to include a rack-and-pinion. In either case, the pressurizing arrangement 242 is such that it permits the flow through the valve to be reversed without changing the operation of the same. Also the differential piston 250 is designed to relate the pressure acting on the seats to that present in the inlet 12.

Abstract: 966, 472. Thread traversing mechanism. S.E.T.I.C. Aug. 2, 1963 [Aug. 10,1962], No. 30660/63. Heading D1J. Thread, fed from a fixed thread guide to a rotating take-up reel to be wound thereon is traversed over the length of the reel by causing the reel to oscillate about an axis which is perpendicular to the axis of rotation of the reel and which passes through the centre point of the reel, the amplitude of the oscillation is selected to cause the planes of the end flanges of the reel to become aligned alternately with the fixed point from which the thread is fed. Thread 17 is fed from a fixed guide point A and wound on a reel 14 forming part of a double-twist thread winding apparatus the reel rotating about the axis XX<SP>1</SP> and oscillating about an axis perpendicular thereto and passing through its centre point B. Oscillation is caused by a radial arm 1 having a roller 2 at its end which engages in a recess 3 in a nut 4 which is moved to and fro along a rotating screw 5 provided with two oppositely handed threads. The amplitude of the oscillation may be varied e.g. for reels of varying axial length by altering the length of the arm 1. Drive to the screw 5 is linked with the rotation of the reel by a suitable gear train (Fig. 3 not shown) and thus the winding pitch and rate of traverse may be determined by the selection of suitable ratios of the gears in the gear train.
