Abstract: 169,899. Moy, E. F., and Bastie, P. H. Sept. 13, 1920. Automatic circuit-breakers. - The tripping- mechanism of a reverse current circuit-breaker of the general type described in Specification 5232/05, consists of a rotatable magnetic structure mounted within the gap formed between the poles of a permanent magnet and an inner fixed core portion carrying a winding through which a portion of the main current flows; the magnetic structure carries a hook which, on rotation, releases a weight to knock out the latch. As shown in Fig. 2, the circuit-breaker is held in the closed position by the engagement of a spring catch 6 with an insulated projection 7 on the member 3 of the closing mechanism, and is tripped by the fall of the guided weight 13 engaging a hardened projection on the catch. When the weight is lifted by hand, a roller 17 thereon automatically engages with a hook formed by recessing the face of a disc 19, the hook having an inclined nose and the recess a cam formation. The disc is secured upon the projecting spindle of a magnet structure made up of two armature segments 23 held together by end plates formed with spindles. A core 29 carrying a coil 30, energized by a shunt in the main circuit, is fixed within the pivoted armature structure to the bracket 28. The poles 31, 32, Fig. 3, of a permanent magnet surround the pivoted armature structure. With current in the normal direction, the pivoted armature experiences a torque tending to reinforce the hold on the roller 17, but with reversal of current through the coil 30 the disc 19 is rotated to free the roller, whereupon the weight 13 falls, knocksdown the lever 9, and raises the latch 6.

The light source 19 may be incandescent or LED, the light being carried through plate 16, reflective coated on its back, to roughened areas 20 opposite the electrodes which are transparent, e.g. SnO 2 . In an alternative design (Fig. 2) the electrodes 20 are illuminated by individual light guides 16. A semi-reflecting layer 15, e.g. with a reflecting coating applied over grooves on the face next to polarizer 14, and opaque insulating and reflecting diaphragm layer 17, e.g. MgO, with nematic liquid crystal material 5 between crossed polarizers, ensures that with source 19 OFF, unsignalled un-energized elements merge with the diaphragm background, signalled energized elements appearing dark. At night the cell is illuminated and the logic is inverted so that signalled elements are de-energized, scattering the polarized light and appearing light against a dark background, while unsignalled energized elements appear dark. The electrodes are supplied with square wave trains of clock pulses, the polarity being selectable so that only energized elements receive an alternating p.d.; the control B to reverse the logic to de-energize signalled elements at night may be combined with the light switch. An exclusive OR gate 12 in electronic control 10 (Fig. 1) or two AND gates with inverters (Fig. 4, not shown) may be used to select the logic.

Abstract: 771,874. Control of A.C. motors. GENERAL ELECTRIC CO. Sept. 16, 1955 [Sept- 16. 1954], No. 26606/55. Class 38(3)  A split-phase motor having running winding 2 and starting winding 3 is pro- 'tected against over-heating when stalled by means of an auxiliary circuit, comprising resistor 14 and coils 17, 18, which is connected in parallel with that portion of the running winding circuit which includes bimetal member 8, heater 9, and relay coil 10, the coils 17, 18, being in transformer relation with the starting and running windings respectively. When the motor is operating normally, a high current passes through the auxiliary circuit so that the current passing through the elements 8, 9, is insufficient to open the spring- biased overload contacts 7. When the motor is stalled, however, or fails to start, no speed-responsive voltage is induced in the winding 17, the current in the auxiliary circuit is reduced, and that passing through the other branch circuit increases until the contacts 7 are actuated to disconnect the motor. A heavy surge of current when the motor is started causes coil 10 to close contacts 11 and energize the starting winding which is disconnected when the motor reaches a predetermined speed.
