Title: Improvements in hydraulic control systems for electrical apparatus
IPC: H01H33/34
Filed: 1959-02-18
Abstract: 844,300. Fluid actuation of switches. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Feb. 18, 1959 [Feb. 27, 1958], No. 5619/59. Class 38 (5). [Also in Group XXIX] An hydraulic system for a circuit-breaker 3A comprises an hydraulic jack 1 which is controlled by two similar hydraulic devices 15, 15A having differential pistons 23 arranged to be actuated rapidly by graduated exhausts of pressure effected by associated control valves 14, 14A which are also similar to one another. The differential piston 23 of the device 15 is spring- urged upwardly to close an orifice 25 in a widebored pipe 30 connected by a non-return valve 29 to a chamber 27 in the device 15A, in turn, connected by a pipe 5 to the jack 1. The lower end of the device 15 is connected to a pump 10 by the control valve 14 which has a chamber 16 closed at each end by spring-pressed balls 18, 19 and a sleeve 21 normally urged to the left by a spring 22. In operation, the pump 10 supplies liquid pressure to the valve 14 to move the sleeve 21 to the right to supply liquid through an orifice to the chamber 16 and to the lower end of the piston 23 of the device 15, and through passageways f1, f2 to a chamber 27 connected to the accumulator 6. When the pressure reaches a predetermined value in the accumulator, the pump is stopped by a manometer and the sleeve 21 returned to the left by the spring 22. The circuit breaker 3A is closed by energization of a solenoid 40 which displaces the ball 18 from its seating to connect the chamber 16 to exhaust 17, the decrease in pressure in the chamber permitting downward movement of the piston 23 in the device 15 and the liquid beneath the piston to displace the ball 19 from its seating and pass to the control valve 14A to assist in pressing its balls 18, 19 against their seatings. The downward movement of the piston 23 closes an orifice 26 at the lower end of the device 15 and opens the orifice 25 to connect the pressure in the accumulator to the jack to move the piston upwardly and close the breaker. When a position of equilibrium is reached, the ball 18 of the valve 14 is returned to its seating and the orifice 25 closed by upward movement of the piston 23, any leakage of pressure from the pipe 30 and jack 1 being replaced by the accumulator through a balance valve 31. The breaker is opened by energization of a solenoid 41 causing similar action to the valve 14A and device 15A to open the chamber 16 in the valve and the orifice 25 in the device to connect the jack to exhaust, a spring 4 assisting in the movement of the piston 2 of the jack. The pipe 30 is also connected to a low-pressure valve 35 which, if the pressure in the pipe or jack falls to a predetermined low level, connects the pipe to exhaust to permit rapid downward movement of the piston.

Title: Improvements in contact arrangements applicable to electrical follow-up switches
IPC: G05D3/12
Filed: 1942-04-29
Abstract: 556,288. Follow-up control systems. PRECISION DEVELOPMENT CO., Ltd., and OLAH, G. April 29, 1942, No. 5728. [Class 40 (i)] [Also in Group XXXVII] Two pairs at least of co-operating contacts such as contacts for controlling a reversible motor are actuated by the relative movement of two contact members, an intermediate member or members located in the path of the switching movement of the contact members, carrying at least one each of every pair of co-operating contacts controlled, and being able to float between the limits provided by the relative displacement of the two contact members when contacts are broken. In one example, Fig. 3, an input shaft moves a central member A bearing contacts co-acting with one or other of spaced contacts C1, D2 on an intermediate member CD, which when driven in one direction or the other by movement of A causes other spaced contacts D1, C2 to co-act with the sides of contact member BX on a driven member B shown as co-axial, with A and CD. Thus if member A moves clockwise contacts A1 and C1 are made and by driving the intermediate member CD contacts D1 and B1 are made establishing a circuit to drive a servomotor operating on the output member B in the same direction. When the driven member overtakes the input member A the circuit is broken and the slow-up operation continues in known manner in one or other directions according to the direction and extent of the input movement. In the example, Fig. 4, the member P is a frame holding the planet wheels of a differential gear the two sun wheels of which are connected with the input and output. The movement in one direction of the input shaft will cause movement of contact member AX into contact with one or other of contacts C1, D2 or a pivoted intermediate member CD which is thereby rocked to cause consequential contact movements between member BX and contacts D1 and C2 to operate a servomotor actuating the output shaft to an extent to cause disengagement.
