Patent GB-960526-A (GB)
Title: Improvements in or relating to anti-skid brake systems
IPC: B60T8/74
Filed: 1962-06-20
Abstract: 960,526. Anti-skid brake control units; valves. FORD MOTOR CO. Ltd. June 20, 1962 [July 3, 1961], No. 23693/61. Headings F2E, F2F and F2V. An anti-skid braking device for vehicle braking systems comprises a skid control unit 10 including rotatably mounted inner and outer valve parts 56, 52 respectively, which normally rotate together by means of a driving connection 60 with the vehicle wheel, the inner valve part having a shaft extension 80 with a leafspring driving connection 86 to a flywheel 84. The leaf spring members 86 serve as driving members between the inner and outer valve parts 56 and 52. Upon rotation of the outer part 52, the inner part 56 will be driven through the springs 86 and in the event of a rapid slow down of the outer part 52, the springs 86 will flex and the flywheel 84 will cause the inner valve parts to overrun the outer valve part 52 and establish an angular relationship. Upon actuation of the brake, hydraulic fluid is forced from a pressure source through inlet connection 14 of the unit 10 and via outlet connection 12 of the unit to the brake cylinders 46 of a spottype disc brake. Normally, both the inner and outer valve parts 56 and 52 are driven at a speed directly proportional to the wheel speed. When the brakes are applied to reduce the wheel speed, the outer valve part 52 will slow up and the inner valve part 56 will tend to overrun the outer valve part 52 because of the inertia of the flywheel 84 and establish a new angular relationship between the two parts which is directly proportional to the amount of wheel deceleration. If the extent of wheel deceleration is so great as to indicate incipient wheel lock the inner valve part 56 is turned relatively to the outer valve part 52 and the brake outlets 98 are in communication with the ports 102 leading to a reservoir and evacuation of the pressure fluid from the wheel brake cylinders 46 will occur. At the same time, the supply inlet ports 92 are closed. Wheel deceleration will immediately stop and the inner and outer valve parts 56, 52 will return to their original positions and pressure will then be re-applied from the supply ports 92 to the brake ports 98. This condition will continue until the vehicle is brought to a halt or the operator releases his brake control.

Title: Improvements in and relating to fluid actuated operating mechanisms for electric circuit breakers
IPC: H01H33/32
Filed: 1944-11-29
Abstract: 619,944. Fluid-pressure servomotor-control systems valves. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 29, 1944, No. 23857. Convention date, Nov. 29, 1943. [Class 135] [Also in Group XXXVII] The invention, which is an improvement on the mechanism disclosed in Specification 548,520, comprises an operating mechanism for a circuitbreaker 10, wherein there is interposed between a source 42 of operating fluid and a fluid motor 38, a valve 81 for substantially instantanously relieving the pressure acting in one direction on the motor to enable high-speed reversal thereof, the valve being operable in response to the back pressure resulting upon the reversal of the motor, and having a non-return valve 88 for increasing its opening speed. Upon overload, a latch 26 is moved anti-clockwise by coil. 31 to allow levers 16 and 17 also to move anti-clockwise to open the circuit-breaker 10. To reclose the circuit-breaker, a switch 60 is closed to energize a time-delay relay 67 and a, valve operating coil 59, which moves a pilot valve 45 upwards, where it is held open by a permanent magnet 57 after the relay 67 opens. Opening of this valve exhausts the space 52 above main valve 46 which opens, at the same time closing an exhaust valve 47. The flow of operating fluid moves the valve 81 to the left (as seen in the Figures) to close exhaust ports 87, at which point valve 88 opens against spring pressure to supply fluid to the cylinder 39 to cause piston 40 to return the levers 16, 17 to the position shown in Fig. 1. At the end of its upward stroke, the piston closes a limit switch 72 to energize a coil 71 which neutralises the holding flux of the magnet 57, thus allowing valves 45 and 46 to close and valve 47 to open, thereby exhausting the space 48 behind the valve 81. The valve 88 now closes and valve 81 moves to the right to open ports 87 so that the piston 40 is free to move downwards again. If the breaker is reclosed on to a fault, a winding 76 energized simultaneously with trip coil 31, closes the valves 45, 46 in the same way as coil 71. A switch 61 opens when the pressure of the source 42 falls below a predetermined value. In a modification (Fig. 3, not shown), the valve 81 faces the opposite direction to that shown in Fig. 2, so as to reduce the volume of the space 48, thereby to increase the speed of response of dump valve 44. Specification 619,943, [Group XXXVII], also is referred to.

Abstract: 226,606. Hailey, F. P., George, W. J., and Little, L. E. Sept. 25, 1923. Couplings, disconnectible; cup-leather overlap joints; swivelling joints; with valves: -Relates to couplings for lubricators, whereby the nozzle of a grease gun is connected to the nipple on the part to be lubricated, of the type wherein one member 4 of the coupling is combined with an elbow joint 3, which permits of a swivelling motion of the coupling relative to the nipple, the connection and disconnection of said coupling being effected by means of a series of radiallymoving balls 8 operable by a spring-controlled longitudinally-movable sleeve 10. The sleeve 10 is partially disposed within a cover 13 which is provided with two opposite guiding slots 12 for the reception of the heads of screws 11 secured on the sleeve 19, thus limiting the motion of said sleeve. Disposed within the coupling is a spring- pressed piston 19 provided with a cup-leather 21 and a central perforation 19<a> normally closed by a spring-pressed ball valve 16. In the action of locking the coupling to the nipple, the nipple makes joint with the cup-leather 21 and also moves the piston 19 and ball valve 16, causing the latter to contact with an eccentric aperture 17<a> in a washer 17 and drop to open the perforation 19<a> to the oil under pressure. Fluid-tightness between the swivelling members 3, 4 is secured by cup-leather washers 6.

Title: Improvements in or relating to thermal storage systems
IPC: F01K1/00
Filed: 1939-08-18
Abstract: 536,603. Thermal storage systems. POLANYI, A. Aug. 18, 1939, No. 23913. [Class 123 (ii)] A thermal storage system in combination with a primary steam raising plant, in which energy is stored when that available from the primary steam raising plant exceeds the demand and from which energy is discharged when the primary steam raising plant is insufficient to meet the demand, comprises a storage capacity mainly constituted by water in a helical or serpentine tube system. The tubes are connected to an expansion vessel from which steam is drawn off, the pressure in the vessel being equal to or below that in the tubes, or equal to or above that in the main. The heat storage capacity may be increased by surrounding the tubes by solids or liquids, or by making use of the supporting structure. The tubes may be embedded in iron filings, metal powder, firebrick, sand, or granulated magnetite. Water is forced by pump 11 into pipe 10 which is heated. Heat is discharged when required by passing the hot water through a throttle valve 13 to a separating chamber 12, the pressure in which controls the valve 13. Steam passes through reducing valve 15 to consumers A, the valve 15 being regulated by pressure in pipe 14. Separated water is returned by pump 16 through valve 17 controlled by water level in chamber 12. In Fig. 3 the separating chamber 12 is replaced by a tube 20 from which steam rises through pipes 21 to a collector 22 and thence to a header 23 and reducing valve 24. Instead of returning the separated water to the storage system, it may be supplied to the next stage of a multi-stage system, or may be utilized as boiler feed. Means may. also be provided to allow water to be drawn direct from the storage pipe for boiler feed. The storage pipe may be heated by flue gases, and may function as an economizer, or the system may form part of a boiler system and may operate at a pressure above that of the boiler.

Abstract: 609,490. Making compound sheets. KINTNEY, J. Sept. 17, 1945, No. 23924. Convention date, July 24, 1944. [Classes 83 (ii) and 83 (iv)] Soldering and brazing.- A method of .making a multi - ply sheet of austenitic stainless steel and oxygen-free copper or silver comprises separately rolling each metal to sheet of substantially final gauge, cutting from the sheets pieces of substantially final form, cleaning the surfaces of the cut pieces, forming a multi-ply assembly by matching such pieces with their cleaned faces in contact then pressing them into intimate contact while maintaining them at a temperature of from 1500‹ to 1850‹ F. for a period sufficient to anneal the stainless steel and to bond the pieces together. A number of sets of component sheets to be bonded are stacked with intervening separator sheets on a base 6 formed with a surrounding trough 10 filled with an inert salt which melts at the temperatures employed. A cover 8 rests on the stacked sheets and the sides 7 of the cover dip into the trough 10 to form a seal. The sheets are heated to the required temperature as by means of resistance elements 11 and are compressed by the press ram 16 bearing on the top of the cover 8. If it is desired to bond outer stainless steel layers to a copper sheet, the steel layers are preferably rolled to a thickness of 0.01 inch and the copper to 0.03 inch. In order to facilitate bonding, the steel is preferably given an undercoating of nickel 0.0005 inch thick and a coating of silver 0.00002 inch thick. Alternatively, the silver may be applied to the copper instead of to the nickel coating of the steel sheet. After assembly in the apparatus, the sheets are heated to 1850‹ F. and pressed for about two hours at a pressure of 1000 lbs. per square inch. The sheets should preferably not exceed 15 inches square. A two-ply sheet of copper and stainless steel or of silver and stainless steel may be formed in the same manner, the bonding temperature being from 1500‹ to 1650‹ F. in the latter case.

Title: Improvements in or relating to apparatus for light source tracking and scanning devices therefor
IPC: G01S3/786
Filed: 1961-07-04
Abstract: 946,424. Light source tracking means. KOLLSMAN INSTRUMENT CORPORATION. July 4, 1961 [Aug. 5, 1960], No. 24139/61. Heading H4D. A scanning device for light source tracking apparatus comprises either a plate formed with an aperture or a photo-electric means, driven, by means coupled to the plate or photo-electric means, in simple harmonic motion about a central position to bring the aperture or the photo-electric means into intermittent registry with an image of the light source. In an embodiment utilizing the apertured plate aspect of the invention, the plate 9, Fig. 2, is formed with an aperture 10 substantially the same size as the source image, and is vibrated in simple harmonic motion by a magnetic reed 8 and a solenoid 13, energized at a frequency fo. When mounted in an automatic tracking telescope 1, Fig. 1, the plate vibrates in a plane 12, through the image of a light source (e.g. a star), produced by lens 2. The interrupted light source rays, impinge via condenser 4 on a photo-electric detector 5, the arrangement being such that the detector output signal is at a single frequency 2 #o if the image is at the central position and further contains a component of frequency fo if the image deviates from this position. The magnitude and phase of the two frequencies are shown in Figs. 4 and 5. Tuned amplifiers, Fig. 10 (not shown), may be used to separate out the two frequencies in the detector output and feed them to control circuits and a servomotor to automatically align the telescope in altitude or azimuth on to the light source, to bring the image to the central position and reduct the fo detector component to zero. The source image may be tracked alternately in altitude and azimuth by housing the base 11 of the magnetic reed 8 in an annular bearing 17, Fig. 6, having a 90 degree arc of movement bounded by stops 18 and 19, and shifting the base from one stop to the other, possibly by means of solenoidoperated mechanism 20. Alternatively, Figs. 11 and 12 (not shown), two alternately vibrated orthogonally mounted reeds and plates may be used, the plates overlapping and being formed each with slit apertures at right angles to the direction of vibration of the respective plate, the apertures coinciding at rest to define a resultant square aperture, at the central position of the source image. Alternatively, the two plates may be simultaneously vibrated in quadrature so that the resultant aperture describes a circular path, the central positioning of the image producing a 4 #o component in the detector-output signal. In the embodiment of Fig. 1 and the variations thereof described, the plate may be replaced by a photo-cell vibrated by the magnetic reed about the central position and giving its output directly to the control and servo circuits. The extent of movement of the aperture or photo-cell is preferably at least three times the diameter of the image. U.S.A. Specification 2,905,828 is referred to.
