Title: Regenerative braking on electrically driven vehicles
IPC: H02P3/14
Filed: 1935-06-21
Abstract: 461,881. Control of D.C. motors. MALEY, A. W., and TAUNTON, E. M. June 21, 1935, No. 17899. [Class 38 (iii)] Regenerative braking.-The regenerative circuits of series motors 1, 2, having field windings 3, 4, each divided into sections which are equivalent to a normal series winding when connected in parallel, are established and regeneration governed upon controller notches other than the power notches, and the circuits include a main circuit in which motor armatures are in series, and a field circuit in which the sections of field winding are connected in series and supplied by a part only of the voltage generated in the main circuit. When the power controller is moved to the " off " position contacts 11 are closed to energize a contactor 6 which connects the series-connected sections of the field windings 3, 4, across the armature of the motor 2. The field windings 3, 4, may be divided into sections each of the same number of turns as the normal winding but of cross-section reduced in proportion to their number as described in Specifications 430,029 and 434,189. When the generated voltage is approximately equal to that of the line a contactor 16 closes to energize a shunt winding 14 of a contactor 13 which completes the connection to the supply. A series coil 15 of the contactor 13 is energized by the regenerated current, and the regenerative supply connection is maintained until the regenerated voltage falls and current flows to the motors. If the regenerated voltage reaches an unduly high value a contactor 22 having a coil 23 connected across the armatures 1, 2 opens to insert a resistance 21 in the field circuit the regenerative braking is controlled by a resistance 7 in the field circuit. The current flowing through the coil of the contactor 16, before the supply connection is completed also passes through the field windings and serves for hastening the building-up of the regenerating field. A second contactor 17 may be provided, operating on small currents and carrying the pre-excitation current, to maintain open the circuit through the coil 14 of the contactor 13, until its operating coil 25 is short-circuited by operation of the contactor 6. The regenerative controller may have air brake notches on the opposite side of its " off " position. The power controller may also have wheel or track brake notches, and be interlocked electrically or mechanically with the regenerative controller, so that when it is moved to its brake notches regeneration is prevented.

Abstract: 996, 355. Testing yarn fault detectors. S. PEYER. May 10,1962 [May 15, 1961], No. 17998/62. Heading G1A. [Also in Division H3] The invention relates to an arrangement for testing a photoelectric yarn fault detector having an adjustable tolerance response, and comprises a selectively operable switch means for periodically varying the supply voltage of the lamp forming part of the yarn fault detector, on an impulse basis, wherein the amplitude of the variation is adjustable. In the embodiment shown the lamps L of fault detecting units F have a stabilized supply voltage provided by a known circuit comprising transistors T 4 , T 5 , T 6  the voltage being determined by a reference voltage at the emitter of T4 which is connected to a potential divider formed by resistors R 1 , R 2  connected across a Zener diode Z. An impulse source to vary the stabilized voltage and hence the brightness of the lamps is connected selectively by a test switch S which initiates the operation of an unsymmetrical multivibrator formed by transistors T 1 , T 2 , negative square pulses, of for example 0.1 sec. at a rate of one per sec., from which are fed to a resistor Re. A further transistor T3 acts as a switch controlled by the said pulses, the normally non-conductive emitter collector path of T 3  being made conductive for each impulse, and a variable resistor R v  is connected in parallel with the resistor R 2  so that the reference voltage for the stabilizer circuit is reduced, the amplitude of the alteration being controlled by adjustment of R v . The tolerance of the units F can be adjusted by adjustment of a potentiometer P.

Abstract: 398,977. Electric-battery lamps. EVER READY CO. (GREAT BRITAIN), Ltd., Hercules Place, Holloway, and BEESTON, F., Iredene, Barrowell Green, Winchmore Hill, both in London. June 29, 1932, No. 18408. [Class 39 (ii).] In electric torches, spot-lights, &c. of the kind wherein focusing is effected by moving a reflector-carrying member relatively to the battery casing or other means supporting the lamp bulb the endwise movement of the reflector-carrying member 4 relatively to the battery casing 1 is limited by means of a ring 7 located within a housing 8 formed between the parts. The upper end of the battery casing is screw-threaded to receive a screw-threaded sleeve 3 which is preferably screw-threaded exteriorly for the reception of an extension 6 on the reflector support 4. Alternatively the members 3, 4 may be formed integrally. A portion of the battery casing is pressed inwardly and an adjacent part of the sleeve 3 pressed outwardly to form the housing 8 for the ring 7, which is preferably split so that it can be compressed to enable the sleeve 3 to be passed over it when assembling the parts, the subsequent expansion of the ring preventing the detachment of the sleeve 3 from the casing. Inward movement of the reflector may also be limited by a flange 9 on the member 4 abutting against the upper end of the battery casing. When the reflector-carrier 4 and sleeve 3 are connected by screwing the latter is preferably in relatively loose screw-threaded engagement with the battery casing to prevent the member 4 from unscrewing completely during focusing. The ring 7 may consist of one or more convolutions of wire.
