Abstract: 647,948. Automatic voltage control systems. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. Dec. 30, 1946, No. 38032. [Class 38 (iv)] In a system in which an electrical output quantity of a generator is adjusted by control means varying the field excitation, the control means also adjusts a reference quantity which is compared with the generator output to provide automatic trimming of generator output to a desired value from which it would deviate only slightly were the automatic trimming to fail. Automatic voltage control of a D.C. generator 2, the separately excited field 3 of which is supplied from A.C. means 8 through a grid-controlled rectifier 7, is effected by a static phase shifter 24 controlled by a thermionic valve 30, the grid cathode p.d. of which is the difference between the variable voltage of the generator and a preset voltage tapped from a potentiometer 27. The main over-riding control of the generator voltage comprises a manually-operated rotary phase shifter 25 connected to cascade with the static shifter 24 and coupled with the adjustable contact 32 of the potentiometer 27. The generator 2 controls a motor 4. The arrangement is such that should the static phase shifter fail only a relatively small change in the controlled generator voltage results and currents of dangerous value are avoided.

Abstract: 1,029,306. Transistor oscillating circuits. HONEYWELL Inc. Oct. 29, 1962, No. 40847/62. Heading H3T. [Also in Division H2] A blocking oscillator comprises: a saturable transformer ; first and second output circuits; switching means coupled to the transformer for establishing periodically a current in the first output circuit and no current in the second, followed by no current in the first and current in the second; and a control means for varying in accordance with an input control signal, the time that the first and second circuits are conducting and non-conducting. A first embodiment, Fig. 1, comprises a pair of common collector transistors 10, 14 connected to a saturable feedback transformer 20 and producing antiphase outputs in the loads 43, 44. The primary winding of the feedback transformer is split into two halves, with a D.C. control signal source 45 being inserted between the two halves. With zero control signal, the duration of the time period of transistor 10 conducting is equal to that of transistor 14 since the saturation voltage of the transformer is the same in both directions. If the control signal is now increased in one sense or the other the transformer becomes polarized, and the mark/space ratio of the output signal is varied since the switching voltages required are no longer equal. In a second embodiment, Fig. 5, resistors 61<SP>1</SP>, 64<SP>1</SP> are included in the collector circuits and the maximum mark/space ratio is increased by including cross-coupling resistors 60<SP>1</SP>, 63<SP>1</SP> from collector to base to prevent unstable operation. The outputs from this circuit are taken from across resistors 95, 96 in the emitter circuits and are fed via further switching transistors 100, 104 to control a servomotor 115. With equal on/off periods, the mean currents in the two field windings 116, 117 are equal and the motor does not rotate. Increasing the control current causes an unbalance in the field windings, so that the motor rotates, the sense of rotation depending on the sense of the control signal. Diodes 121, 122 and Zener diode 123 protect the transistors from surge currents when the fields round the coils 116, 117 collapse, and diode 125 shorts the armature when its field collapses to provide braking. Fig. 4 (not shown) discloses an oscillator similar to that of Fig. 5 in which the outputs are taken from across the collector load resistors.
