Title: Fluid operable braking system
IPC: B60T13/36
Filed: 1966-09-15
Abstract: 1,112,404. Fluid-pressure brakes. COMPAGNIE DES FREINS ET SIGNAUX WEST INGHOUSE. 15 Sept., 1966 [16 Sept., 1965], No.41182/66. Heading F2F. In a compressed-air braking system for a road vehicle of the kind which includes locking rollers 12 which are engageable with piston-rod 15 of an actuator cylinder 6, under the action of spring 14, and are releasable by a piston 13 when compressed air is supplied to a chamber 1 11bis, an emergency/park control valve 8 is provided, operable manually by a handle 16 adapted to rotate a cover 41, Fig. 4A, about an axis 19 to control, through mating camming members 42, 47, the calibration of a spring 49 controlling a self-lapping valve assembly 48, 50 feeding air to emergency chamber 10bis and, in addition, to control, in the park position, beyond the range in which the calibration of spring 49 is varied, a further valve assembly 56, 57 so as to cut off the supply of air to the chamber 1 11bis, the arrangement being such that when the handle 16 is moved from the park position to the range in which air is supplied to the chamber 11bis to release the locking rollers and a controlled air pressure is supplied to the chamber 10bis, the pressure supplied to the chamber 10bis is initially higher than that which obtained at the time the locking rollers were engaged by movement of the handle 16 into the park position. For this purpose, the cam 42 has a special profile (Fig. 4c, not shown), such that the compression of the spring 49 controlling the self-lapping valve assembly 48, 50 reaches a maximum before the point at which handle 16 enters the park position and then falls to a lower value, causing a reduction of pressure in the chamber 10bis on reaching this point. The locking rollers 12 are thus applied to the piston-rod 15 when a pressure less than the maximum pressure is present in the chamber 10bis and, conversely, when the handle 16 is returned to the emergency braking range, the pressure in the chamber 10bis is temporarily increased to assist release of the locking rollers by re-application of pressure to the chamber 11bis. Handle 16 is slidable along a rod 43 against the action of a spring and must be thus pulled out to enable a flange 44 to clear the end of a guide 69 before movement to and from the park position can be effected. The valve 56, 57 is controlled via a plunger 65 by a cam surface 68 on the cover 41. It is also independently controllable by pressure in a service brake line 7 which is arranged to act on a piston 55 integral with valve member 56, in addition to its acting in a service chamber 4bis of the actuator cylinder 6. separated from the emergency chamber 10bis by one of two pistons (24, 26, Fig. 2, not shown) acting on the rod 15. A non-return valve 61 bypassed by a calibrated orifice 63 causes release of air from the chamber 10bis to be effected gradually when handle 16 is in the park position.

Abstract: 1,170,232. Fluid pressure brakes. SIMMS GROUP RESEARCH & DEVELOPMENT Ltd. 28 Dec., 1966 [29 Sept., 1965], No. 41282/65. Heading F2F. In an apparatus for providing fluid pressure to operate a vehicle wheel brake, the pressure is generated by a pump 1 adapted to be driven at a speed dependent on the speed of rotation of the vehicle wheel so that less fluid is pumped to the wheel as the latter tends to lock, thereby reducing the braking force. When the apparatus shown in the Figure is mounted in a vehicle, the pump 1 is associated with one wheel of the vehicle such that the pump 1 pumps fluid from a tank 12 and developes pressure in a conduit 2 which, through a conduit 8, is supplied to brake cylinders associated with that wheel. When a valve member 5 of a pressure control valve device 3 remains unactuated by pressure from a brake master cylinder (not shown) through a conduit 4, substantially no pressure is supplied to the wheel brake cylinders of that wheel as the hydraulic circuit formed by conduit 2 and the open valve member 5 allows the fluid to return to the tank 12. On actuation of the brake pedal the master cylinder is actuated to displace the valve member 5 in the conduit 4 against the action of a spring 7 to restrict the flow of fluid back to the tank and to increase the pressure in the conduit 8 leading to the wheel brake cylinders to apply the brakes associated with the wheel. Should the wheel lock, the pump 1 will cease to rotate and the fluid is returned to the tank 12 via restricted orifice 10 in the line 9a to reduce the braking force. Should the build-up of pressure in the conduit 2 exceed a predetermined value, a spring-loaded release valve 11 opens to permit escape of pressure in the conduit 2 back to the tank 12. A plurality of pumps 1 may be associated one with each wheel and supplied by a common tank 12. The gear-wheel pump may be replaced by a transfer pump and it is stated that a clutch may be incorporated so that only when the brake pedal is depressed is the pump arrangement rendered inoperative to pump fluid into the conduit 2.

Abstract: 1285445 Access control equipment SMITHS INDUSTRIES Ltd 29 Aug 1969 [30 Aug 1968] 41425/68 Headings G4T G4V and G4X  In access control equipment comprising a central station and at least one terminal station, the or each terminal station is adapted for receiving a request for access and for transmitting information concerning the request to the central station, the terminal station and the central station each include means for deriving a word from the information by using the same wordderiving programme, the central station is operative in dependence upon the information to transmit the derived word to the terminal station to signify approval of the request, and the terminal station is arranged to operate access means on receiving the approval signal providing the latter corresponds to its own derived word. The equipment described is identical with that described in Specification 1,285,443. Fig. 6 shows the word-deriving means at the terminal station. Similar means (not shown) are provided at the central station. When a customer finishes entering his personal identification number to a store 43, a unit 71 selects and stores the random sixteen digit binary number being generated at 70 at that time. The state (0 or 1) of these sixteen digits is used by unit 76 to determine which of sixteen gates 74 are open. A particular one of several programme cards is inserted at 76 to determine which gate is controlled by which digit. The gates 74 determine which bi-stable stages of a sixteen stage shift register 73 have their outputs added at 75. As each of a series of pulses enters the register at 67, the lowest order digit of the sum registered at 75 is entered in stage I of the register, whilst all other stages assume the state of their next lower order stage, i.e. stage n assumes the state of stage n-1. The feedback configuration of a corresponding shift register at the control station is identically arranged, the random number selected at 71 being fed to the corresponding unit(76<SP>1</SP>) and the same programme card being used at (76<SP>1</SP>). The number initially held by the register is determined by unit 78 in accordance with the customers account number fed from store 43. The initial condition of the register at the central station is set in the same way. After a programmed number of shifts, i.e. after a programmed number of pulses at 67, the number then held by the two registers is held in means 77, (77<SP>1</SP>). If the central station determines that the status of the customers account &c. is satisfactory, the number held at (77<SP>1</SP>) is sent to the terminal station as the "approval" signal and if 72 finds this signal identical with that held at 77, a signal is sent to a gate 56 to operate the access means.

Weft 23 from a bobbin 14.is fed to longitudinally moving belts 1 which revolve about a shaft 5 so that a coil 22 is formed which is drawn off endwise in a balloon 41 and is fed to a weft inserter, e.g. a gripper shuttle. The continuous draw-off from the bobbin 14 is in excess of the pick so that the coil 22 rides over and depresses levers 15 which move the belt support 6 to engage braking surfaces 21, 28 to reduce the draw-off to maintain a constant supply. The belts 1 (Fig. 7, not shown) may be moved outwardly in place of the levers 15. In Fig. 4 the weft 23 is drawn through a ring 24 on a disc 25 which revolves with the belts so that, when draw-off is equal to insertion, the ring 24 is stationary. In Fig. 8 the weft 23 is fed to the inside of the belts 1 by rollers 67, 66.

Abstract: 1,183,370. Grinding crank-shafts. CHURCHILL MACHINE TOOL CO. Ltd. 24 Sept., 1968 [13 Sept., 1967], No. 41872/67. Heading B3D. A method of grinding a crank-shaft 2 comprises rotating the crank-shaft by workhead means 5, maintaining the axis of rotation of a part of the crank-shaft being ground substantially coincident with the axis of the workhead means, and producing a cyclic variation in the depth of cut into the crank-shaft in accordance with the rate of rotation of the crank-shaft so as to grind the part in such a manner that the desired axis of the part is brought on to the axis of rotation of the part. The maintaining of the axis of rotation is effective by steadies 4 on a support 5 longitudinally slidable on a base 1. A slide 6 is traversable longitudinally of the base and carries a transverse slide 7 formed with a pivot 10 for a frame 8 mounting the grinding wheel 9. The frame rests on an eccentric 11 which is rotated in synchronism with the rotation of the crank-shaft. A clock-type micrometer gauge 14 is disposed on the support 5 for engaging the journal 13 of the crank-shaft. The gauge is adjusted initially so that it indicates the difference between the desired and actual throws of the crank-shaft. During grinding, the eccentric oscillates the grinding wheel to produce a cyclic variation in the depth of cut of the wheel and the steadies are continuously adjusted until the crank-pin is ground such that the crank-shaft has the desired throw. The rotation of the eccentric is stopped to permit finish grinding of the crank-pin. In other arrangements, the cyclic variation may be produced by movement of the steadies or the slide 7. The invention may be applied to the grinding of the journals of the crank-shaft.
