In an electro-mechanical disc brake, for an electric motor of the kind in which a brake disc 13 secured coaxially on the motor shaft 11, is arranged between non-rotatable movable brake members 14 and 15, which are normally biased towards each other to exert a braking pressure on the faces of the disc 13, when the motor is switched off, the movable brake member is movable against the bias of spring 27 to release the braking pressure, by an electro-mechanical mechanism, the mechanism being energized when the motor is switched on. A solenoid 35 is arranged at one side of the axis of the motor shaft, and operates a lever 32 extending from the solenoid to a pivotal connection 31 at the opposite side of the axis to one of the brake members 14. The movable brake members are interconnected by a spring system biasing them towards each other to grip the disc 13 between them. The other movable brake member has in the path of movement of the lever an abutment which will be acted upon by lever 32 when the solenoid is energized to overcome the spring system bias whereby to release the grip of the movable brake member on the disc.

Abstract: 350,418. Oil-break switches. WHITNEY, W. B., WEDMORE, E. B., and BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, 36, Kingsway, London. Dec. 9, 1929, No. 37752. [Class 38 (v).] Arc-rupturing devices.- In a circuit-breaker of the type in which a flow of insulating liquid can take place from a container by reason of the opening or enlargement of an outlet, so as to prevent arcing, the means for producing the flow of liquid comprises a compressible cushion, or equivalent, operation on the surface of the liquid, the liquid being arranged to flow under a pressure head to compress the cushion for use before relative movement between the electrodes to break circuit commences. The movable contacts 30 of all phases are mounted on a frame 31 .. 34 actuated by a pair of rods 35 passing through sleeves 67 in respective cylinders 13. The sleeve 67 leads to a pipe 65 and reservoir by means of which a head of liquid is maintained so as to compress a pocket of air or gas 68 in each container 13. A hollow conical insulator 17 has an oiltight joint with the casing 10 and the mounting 16 for each fixed electrode 15, the latter being in sections which are held in position by a two-piece screwed ring 18 and helical spring 19. The mounting 16 is threaded into a hood 20 and engages, in the closed position of the switch, with a valve 63 on the moving contact 30. Valves 71, 72 on the rods 35 engage, respectively, upper and lower seats on a sleeve 69 around which is a further air cushion. When the rods 35 are lowered to open the switch, the cushion 68 causes a flow of liquid past the valve 72, which flow raises the pressure in the casing 10 and compresses the lower air cushion. At the same time the valve 63 leaves the mounting 16 and a stream of liquid is squirted through the contact 15 to extinguish the arc, the hood 20 deflecting the liquid and preventing it from obstructing the flow of further liquid. When the valve 71 reaches its seating, further flow due to the cushion 68 ceases and the latter is compressed ready for a further operation. The lower cushion, however, prolongs the flow for a further period. Owing to the arrangement of the valves 71, 72 a similar action takes place in closing the switch. Numerical examples are given in the Specification, which further describes a switch in which the pressure is supplied by a pump to a spring-plunger cushion arrangement, the plunger surrounding the sleeve 67. Specification 330,616, [Class 38 (v), Electric switches &c.], is referred to. The Provisional Specification refers also to an arrangement wherein the contacts make two movements in opening, with a period of rest between them.
