Abstract: 515,303. Field control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., and FOX, K. M. April 25, 1938, No. 12355. [Class 38 (iii)] The field 4 of a motor 1 is fed from a potentiometer resistance 5 in circuit with which is a variable voltage source 6 by adjustment of which the variation of voltage applied to the field effected by a given movement of the potentiometer 5 can be made of any desired value. The invention is applicable particularly to multimotor drives in which the motors 1 are fed from a variable voltage source 2, 3, the regulator 10 for the field 11 of a generator 6 connected in circuit with the potentiometer 9 across a constant potential source 7, 8 being adjusted to give low voltage across the potentiometer when the motor speed is high and a higher voltage when the motor speed is low. Thus for a given adjustment of the potentiometer, a smaller charge in the voltage applied to the motor field is effected at high speed than at low speed. The generator 6 may be replaced by a variable resistance and may be common to a number of motors. The constant voltage source 7, 8 may be constituted by the source 2, 3.

Abstract: 1,262,667. Supply circuits for discharge lamps. GENERAL ELECTRIC and ENGLISH ELECTRIC COMPANIES Ltd. 1 May, 1970 [11 March, 1969], No. 12714/69. Heading H2H. A supply circuit for a discharge lamp 18 comprises a rectifier-capacitance arrangement 3-6 connected to supply the lamp with unidirectional current pulses due to the capacitance charging from the supply and discharging through the lamp and a variable impedance network which has a low impedance when the current supplied to the lamp is below a predetermined value and a relatively high impedance when the current supplied to the lamp exceeds this value. The variable impedance network includes a transistor 10 which is initially biased into a highly conducting condition via a resistor 13. When the current through the lamp reaches its maximum desired value a Zener diode 14 breaks down thereby maintaining the voltage across a resistor 11 at a constant value to limit the current through the lamp. A thyristor 15 protects the transistor against excessive voltage. Several modifications of the rectifier-capacitance arrangement are described and the circuit may supply a sodium or mercury vapour lamp.
