Title: Improvements in and relating to fluid pressure control apparatus
Inventor: WILKINS BERNARD CHARLES JOSEPH
IPC: F15B21/08
Filed: 1957-11-20
Abstract: 909,823. Fluid-pressure brakes. ENGLISH ELECTRIC CO. Ltd. Nov. 18, 1958 [Nov. 20, 1957], No. 36157/57. Class 103 (1). Fluid pressure-control apparatus comprises a valve member 21 movable from a neutral position to connect a conduit 16 with a fluidpressure source 22 or with exhaust passage 20, an electrical transducer means 25 exerting a controlling force on member 21 to connect conduit 16 with source 22, the controlling force being dependent solely on the magnitude of the control signal applied to means 25, and feedback means 27 exerting a feedback force dependent on the pressure in conduit 16, on the member 21 in opposition to the controlling force. The brake 10-12 biased by a force F to the applied position, is released by pressure from conduit 16 acting on piston 13 on energization of transducer means 25. The pressure in conduit 16 acts in feedback means 27 on piston 29 to move valve 21 to a neutral position closing both passages 19, 20 when the forces from the transducer and means 27 on the valve member are equal. A reduction in the magnitude of the signal in transducer 25 permits means 27 to move valve member 21 to open passage 20 to release fluid from cylinder 15 and reapply the brake by force F, the valve member returning to a neutral position on balancing of the forces on it. The force F may be a fluid pressure, a weight or a spring acting on the piston 13. In modifications of the feedback means, in Fig. 2, not shown, fluid from cylinder 15 and conduit 16 acts on a reduced under surface of the lower land through ports in the land; and in Fig. 3, not shown, the lands are of different areas so that fluid from conduit 16 gives an upward bias to the valve. In Figs. 4 and 5, not shown, a weight controlled by a solenoid and fluid pressure controlled by an electrically-operated valve respectively, may be used to bias the valve member 21 down on de-energization of the transducer to apply the brake with a force below the normal maximum force; the weight may be replaced by an electrically-controlled spring. Specification 863,262 is referred to.

Abstract: 899,613. Press-button retractive switches; indicators for switches. SMITH & SONS (ENGLAND) Ltd., S. Oct. 27, 1960 [Nov. 4, 1959], No. 37408/59. Class 38 (5). [Also in Group XXXV] A push-button switch which is operated manually to disengage an aircraft automatic pilot (see Group XXXV) is provided with a greater opposition to operation when the automatic pilot is functioning than when the automatic pilot has been disengaged. Operation of a push-button 59, Fig. 3, moves contacts 72 relative to fixed contacts (not shown) to deenergize self-holding relays (not shown). An electromagnet 56 connected in parallel with the relays attracts an armature 63 and thereby increases the initial force necessary to operate the push button. If, however, the operator experiences only the much smaller resistance of a spring 64 when operating the push button, he knows that the relays have already been deenergized and the automatic pilot disengaged by some other means. A spring 62 provides a further increase of resistance to operation when a telescopic member 61 meets a fixed member 52 during operation of the push button.

Class 27 A vending machine comprises a number of article magazines M arranged in two tiers T-1, T-2 and at least some of the magazines are provided with means for holding a reserve stack S-2 of articles behind the primary stack S-1 and for advancing the reserve stack when the primary stack is depleted. In each magazine, the lowermost article of the forward stack is supported on an ejector E until the ejector is withdrawn by pulling a knob 65 and spring return of the ejector then pushes the article off a shelf 29 to a delivery trough 241, articles from the upper magazines being directed by a plate 47 to drop behind the lower magazines. The ejectors of the upper and lower magazines are coupled to interlock levers 137, 139 co-operating with coinfreed latches L-1, L-2, L-3 which are operated through price-change shafts 185 and 187 as described in Specification 799,720. When an ejector in one tier is operated the movement of one interlock lever blocks the movement of the other so that all the ejectors in the other tier are locked and, in the first tier, a nose 77 on the operated ejector spreads tumblers 69 so that all the other ejectors in that tier are locked. Full-stroke pawls 171 co-operate with teeth 153 on the interlock levers. On depletion of a primary stack of articles, the reserve stack is moved forward by a pusher plate 87 operated by spring-loaded lazy tongs 89, the plate preferably being angled slightly rearward so that the reserve stack does not tend to wedge the uppermost articles in the primary stack. A side plate 111 extends forwardly from the pusher plate and at the forward end of the side plate is a spring-loaded hinged flap 115 which is normally held in a transversely-extending position by a finger 121 engaging the side wall of the magazine, thus forming a partition between the two stacks; when the pusher plate is fully forward and a door 123 is opened, the flap is allowed to swing outward to allow reloading. To relieve the primary stack from the pressure of the reserve stack when an ejector is operated, each ejector is coupled to a rockshaft 223 carrying pawls 225 which engage teeth 221 on each pusher plate to move it slightly backwards.
