Title: Improvements in the control means of electromagnetically operated electric switches or circuit breakers
IPC: H01H47/10
Filed: 1940-06-17
Abstract: 539,343. Electromagnetic switches. COATES, W. A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 17, 1940, No. 10489. [Class 38 (v)], Relates to electromagnetic switches or circuitbreakers wherein the closing coil 1 of the circuitbreaker is fully energized by momentary operation of a switch 5, 6 and has inserted in series with it a first economy resistance 2 when switch 5, 6 is opened and a second economy resistance 3 when the circuit-breaker 1 is closed or nearly closed. An overload switch 12 is also arranged to short-circuit, the coil 1 on overload. According to the invention to prevent continual opening and closing of the circuit-breaker should an overload exist at the same time as the contacts 5, 6 are held in engagement, a control coil 13, energized when the contacts 5, 6 are closed prevents short-circuiting of the second economy resistance after the circuit-breaker has once been closed, so that should the circuit-breaker open owing to an overload, the current tending to reclose it will have to pass through the resistance 3 and will not be strong enough to effect closure. The coil 13 by itself is not strong enough to operate the switch in the arrangement shown but holds it operated. In a modification, the coil 13 acts with delayed action on an auxiliary switch short-circuiting the resistance 3.

Filed: 1945-04-26
Abstract: 590,970. Arc-rupturing in switches. REYROLLE & CO., Ltd., A., and FELCE, A. April 26, 1945, No. 10519. [Class 38 (v)] In an air-break circuit-breaker, a coil to drive the arc into a chute is energized only after a delay so that it can be traversed only by small currents having insufficient inherent magnetic effect. The arc formed between contacts A', C' is transferred to arcing horns B, D as the contact C' passes through a slot in the horn D. Magnetic side plates G on either side of the arc assist it to rise immediately on the horns B, D, if the arc current is large enough. If the arc is small and persists until the contact C reaches a fixed contact E, a coil J of many turns on a magnetic core H is energized and the arc is driven into the chute. The chute may be provided with are-splitters and with a further coil of a few turns only connected between the fixed contact and external circuit.

Abstract: 931,799. Electrically - released switches. GENERAL RAILWAY SIGNAL CO. March 23, 1961 [March 30, 1960], No. 10661/61. Class 38 (5). In a relay retained set by permanent magnetism, the permanent magnet 43 is mounted on yoke 11 so as to saturate a slotted portion 21 of the yoke between the poles of the magnet. There are three main paths for the permanent magnet flux: I, from the N pole along part of yoke 11 to the S pole ; II, from the N pole along yoke 11 through armature 23 and its magnetic backstop 27 and across air-gap A to the S pole; and III from the N pole along armature 23 across air gap B, through core 13 and yoke 11 to the S pole. In the first path is provided the slot 21. In the released position shown, since air gap A is smaller than B the reluctance of path II is smaller than that of path III and the permanent magnet attracts that end of the armature provided with magnetic back-stop 27. If solenoid 19 is now energized to provide a south pole at the left-hand end of the core 13 the electromagnetic flux opposes the permanent magnet flux and the armature is attracted to the core against the bias of a spring 40 and spring- sets 36, 37, 38. The armature is retained in the new position because the reluctance of flux path III is less than that of flux path II. In order that there is no leakage flux in the air-gaps B of adjacent relays, the left-hand end of the core is left unwound.

Abstract: 884,302. Automatic exchange systems. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 2, 1958 [April 4, 1957], No. 10673/58. Class 40 (4). In a matrix of thyratrons in which the firing of one thyratron locks out the remainder of the thyratrons in the same column by virtue of a common anode load for each column, the lockout is further reinforced by additional lock-out conditions applied to the grids of the column. As shown, selection of a thyratron is effected by changing over one of contacts Hi . . . Hp (say Hi) and causing one of transistors Vi . . . Vj . . . (say Vj) to conduct. The latter applies anode potential to the jth column via a load resistance Rj and the former applies striking voltage Vs to the grids of the ith row via the left-hand ones of pairs of resistors d. Transistors Tj is conducting at this time and applies striking voltage Vs to the right-hand resistance d of the jth column so that the grid receives voltage Vs and the tube fires. After a short delay imposed by the condenser C, voltage Va applied by the collector of Vj to the base of Tj cuts the latter off so that now a smaller voltage Vh is applied to the right-hand resistor of the pairs d in the column. As a result when an attempt is made to strike another tube in the column, by applying voltage Vs to its left-hand resistor d, the voltage applied to the grid is only ¢ (Vs + Vh) which is insufficient to fire the tube. The switches Hi . . . Hp may be replaced by transistors. Alternatively, the transistors Vi . . . Vj, Ti . . . Tj may be replaced by switches. The tubes when fired control the connection of corresponding horizontal and vertical A.C. path as described in Specification 830,093.
