Title: Improvements relating to fluid pressure transmission systems
IPC: F16D65/22
Filed: 1947-12-30
Abstract: 646,825. Fluid-pressure brakes. FIAT SOC. PER AZIONI, and BALDWIN, P. S. Dec. 30, 1947, No. 34743. Convention date, Oct. 21, 1943. Addition to 646,824. [Class 103 (i)] [Also in Group XXIX] A fluid-pressure actuator has a conventional piston 21 and a compound piston as in the parent Specification but is characterized in that the valve for controlling the supply of pressure fluid is wholly enclosed within the cylinder. Pressure-fluid is admitted to the cylinder 1 via the inlet connection 3 and passes through conduit 29a to the interior of the expansible element 16 and also past the grooves in the valve piston 11 and the aperture 14 in the metal stop washer 13 into the space behind the conventional piston 21. When the pressure exceeds a predetermined value, the force acting on the front face of valve piston 18 overcomes spring 19 and the valve piston 18 moves to the right, followed by the push-rod 15 and the valve piston 11, which then seats on the sealing ring 10 to trap the liquid behind the piston 21. Fluid is then directed solely to the interior of the expansible element 16 which then exerts an axial force on the part 20 due to the tendency of the arcuate springs 17 to straighten. When the fluid pressure in the inlet drops below the predetermined value the spring 19 will move the valve piston 18 to the left, thereby unseating the valve piston 11 through the action of the push-rod 15 and the fluid behind the piston 21 is released.

Abstract: 1,062,154. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. Sept. 12. 1963 [Sept. 14, 1962], No. 35063/62. Heading H2K. A protective arrangement includes a plurality of input circuits 15 ... 17 and a like plurality of bridge rectifiers 10 ... 12 with smoothing circuits connected to their D.C. terminals which are interconnected to provide an output proportional to only the largest mean value of the current in any one of the rectifiers. The input circuits may be current transformers as shown, the bridge rectifiers being connected in series with capacitors 18 . . . 20 constituting the smoothing circuits. Alternatively, the input circuits may be transformers to which voltage input signals are supplied. In this ease the rectifier bridges are connected in parallel and the smoothing circuits may be chokes. The output of one of the currentresponsive arrangements may be applied to a motor pattern time-overcurrent relay. Fig. 2 shows two current-responsive arrangements interconnected by pilot lines 33 and protecting a section 32 of a polyphase line against internal fault conditions. A polarized relay 37 connected to each arrangement operates when the highest current applied to that arrangement sufficiently exceeds that applied to the other, the relays operating successively when an internal fault fed from both ends occurs. In a modified system, Fig. 3 (not shown), each polarized relay has a restraining winding and an operating winding, the latter being connected in the pilot circuit by a further bridge rectifier so as to respond to current in either direction so that both relays operate simultaneously. In both these systems the current transformers are connected to the neutral conductor to provide earth fault protection. To provide protection against faults fed equally from both ends, a simple directional or circulating current A.C. phase comparison system may be added.
