Title: Electronic switches
IPC: H03K17/74
Filed: 1951-04-13
Abstract: 694,411. Gating circuits. STANDARD TELEPHONES & CABLES, Ltd. April 13, 1951 [April 14, 1950], No. 8656/51. Class 40 (vi). A rectifier gating circuit of known type in which a series arm contains two oppositely poled rectifiers rendered conducting or non-conducting by a switching voltage applied to their common point, is modified by the provision of shunt paths whose impedance is high when the series impedance is low and vice versa. As shown in Fig. 2, point 12 is connected to a positive biasing voltage and point 11 is connected to a switching voltage which is either negative or has a positive value greater than the biasing voltage. In the former case the series rectifiers 13, 14 are backbiased and the shunt rectifiers 18, 19 are forward biased to provide a high loss between points 9, 10. In the later case rectifiers 13, 14 are conductive and the values of the resistance elements are chosen so that points 20, 21 are at a higher potential than that of point 12 so that the shunt rectifiers 18, 19 are back-biased, a low-loss path between points 9, 10 being thus provided. In a modification, Fig. 3, four series rectifiers 25 ... 28 and four shunt rectifiers 39 ... 42 are provided in order to improve the ratio between the losses in the open and closed condition of the network.

Abstract: 725,852. Exciting dynamo-electric machines. IGRANIC ELECTRIC CO., Ltd. April 8, 1953 [April 17, 1952], No. 9535/53. Class 35. [Also in Group XXXVII] A variable voltage system for hoists comprises a compound motor M having a separatelyexcited field winding 13 and a series field winding 32 which is connected in series with a rectifier 39. This rectifier is so connected that, when a master controller 18 is moved in the hoisting direction, the auxiliary series field winding is in circuit and acts accumulatively with the field winding 13. However, in power lowering, the rectifier 39 prevents energization of the winding 32, but if the load is such as to cause the hoist motor to regenerate, the rectifier allows the auxiliary series field winding to be excited accumulatively with the field winding 13. The motor is supplied from a generator G having a separately-excited field winding 15 adapted for variable and reversible excitation according to the position of the controller 18 so as to provide a plurality of hoisting and lowering speeds for the motor. The generator also has a series auxiliary field winding 31 which is included in circuit in the first and second hoisting positions of the controller and acts accumulatively with the field winding 15 under these circumstances. The field winding 31 is also included in circuit in the first lowering position of the controller when it is used accumulatively with the separately-excited field winding for power lowering and differentially for regenerative lowering. The generator auxiliary series field winding is excluded from circuit on all other operating points, the voltage output being controlled by regulating resistors 19-22 in circuit with winding 15. As shown, the field windings 31, 32 are connected across separate resistors 33, 38 in the loop circuit. In a modification, the auxiliary series field windings are connected across a common resistor by means of adjustable taps, Fig. 2 (not shown). The field winding 15 is connected across the armature of the generator in the " off " position of the controller so as to reduce circulating current in the loop circuit.
