Title: Improvements in or relating to automatic electric circuit breakers
IPC: H01H71/16
Filed: 1955-02-28
Abstract: 765,276. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 28, 1955 [March 3, 1954], No. 5818/55. Class 38(5) Ambient temperature compensation for the bimetallic tripping element 45 is provided by securing the element 45 near one of its ends to a portion 70 of a resilient conductor 29, the pressure on which portion may be varied by means of a U-shaped compensating bimetal 81 having a screw 93 screwed into one leg 87 so as to maintain a constant overlap between the latch 67 on the end of bimetal 45 and a carrier 33 pivoted at 41, release of which by the latch 67 on overload trips the breaker. The high expansion part of the compensating bimetal 81 is on the inside of the U so that on a rise in ambient temperature leg 89 and ears 97 will bent towards the left while leg 87 will bent towards the right when resiliency of part 70 of conductor 29 acting through screw 93 and leg 72 of bimetal 45 allows the yoke 85 and leg 87 to move towards the right maintaining ears 97 in contact with shoulders 99 on the switch base. The bending of leg 87 towards the right moves the screw an additional distance towards the right thus permitting further movement to the right of leg 72 and part 70. Since the high expansion side of bimetal 45 is on the outside of the loop at the upper end and to the right of leg 72 the increase of ambient temperature will cause the loop to close thus moving leg toward part 70, which can be further moved to the right by the resiliency of strip 29. The cumulative deflection will thus permit sufficient movement of the part 70 and therefore of pivoting of strip 29 about screw 71 to move the latch towards the left and maintain a constant overlap with carrier 33. An electromagnet having an armature 63 mounted on bimetal 45 and a yoke 65 mounted in recesses 66 in housing 11 and cover 13 for limited movement relevant to armature 63 is provided for immediate tripping on short-circuits or severe overloads, the current through bimetal 45 then energizing' the electromagnet sufficiently for yoke 65 to attract armature 63 thus releasing carrier 33. In another embodiment (Fig. 2, not shown) less temperature compensation may be provided by using the compensating bimetal alone and omitting the loop at the top of the tripping bimetal, while for even less temperature compensation, Fig. 4, the compensating bimetal is omitted and a screw 93 and nut 101 is provided, the former acting directly on the leg 72 of the bimetal 45 and the latter being pressed against shoulders 99 by the resiliency of strip 29. Since the high expansion side is on the outside of the loop an increase in ambient temperature causes leg 72 to bend toward the part 70 and a decrease will cause leg 72 to bend away' from it, thus compensating the bimetal for changes in ambient temperature. The movable contact arm 37 can also be operated manually, a spring 39 imparting a snap action in both directions.

Abstract: 974,681. Phase detectors. STANDARD TELEPHONES & CABLES Ltd. Feb. 8, 1963 [Feb. 15, 1962], No. 5858/62. Heading H3A. Two A.C. voltages are phase compared by applying pulses P, Q from them to opposite sides A, B of a bi-stable circuit F3 through AND-gates G3A, G3B which are enabled (opened) alternately but not by every pulse P, Q applied to them. To this end a further bistable switch F2 operated alternately to opposite states by one set of pulses P, applied to opposite sides of F2 through AND-gates G2A, G2B which are alternately enabled from one side A of F3 and from the corresponding opposite side B of bi-stable switch F2. The other side B of output bi-stable circuit F3 then produces rectangular waves of duration greater than the interval between successive Q pulses and dependent on the phase difference between P, Q and the two A.C. voltages which rectangular waves, e.g. through a telegraph line L, operate a meter V. Preferably the pulses P, Q, render non-conducting the sides of the bistable circuits to which they are applied and non-conduction produces an enabling output voltage to the gates. The A.C. waves may be converted to pulses by applying them over Zener or other diodes forming trapezoidal waveforms, which are then differentiated and output pulses of one polarity then suppressed.

Filed: 1961-02-20
Abstract: 920,302. Spray-producers. V. C. HANSEN, [trading as VOLMATIC]. Feb. 20, 1961 [March 2, 1960], No. 6184/61. Class 69 (3). The supply of liquid by a pipe 1 to liquid dispensing plant is automatically controlled by means of a container 3 supplied with liquid from an outlet 6 of the pipe, so that when the liquid in the container reaches a predetermined level 5 a regulator 2 in the pipe is automatically closed. Several outlets 6 are provided, from which lead different lengths of flow-resistant hose 7, and one or more outlets may be opened to thus vary the time taken for the liquid to reach the " shut-off " level and thereby control the dispensing period. Similarly, cocks 8 with flow-resistant hoses 9 lead into a tube 10 feeding back to the pipe 1 via a non-return valve 11. One or more of the cocks are opened so that when the regulator 2 is closed the valve 11 opens and allows liquid to drain away from the container 3. When the level in the container reaches a position 4 the regulator is again automatically opened, the valve 11 closed by liquid supply pressure and a fixed quantity of liquid dispensed. The dispensing and non-dispensing periods are adjusted by opening various ones of the cocks 6 and 8. In Fig. 2, the liquid supply pipe 13 has a valve 14 controlled by a float 16 adjustable along a lever 16. The container 20 is fed from a cock 18 and a flow-resistant hose, and at a liquid level 22 the valve is closed, and at a level 21 is opened. Flow from the container is via a flow-resistant hose 23. The dispensing period is adjustable by moving the float along the lever, and the " shut-off " period is adjusted by vertically adjusting the outlet of the hose along a scale 24.
