Abstract: 359,880. Maintaining proportional speeds. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) June 5, 1931, No. 16482. Convention date, June 6, 1930. [Class 38 (iii).] Field control.-For maintaining definite speed relations between the several motors driving, for example, the separate units of a paper-making machine, a compressible carbon resistance is used as the synchronization regulating device. A synchronous motor h connected to a supply g common to the synchronous motors associated with all the units, drives the casing of a compressible carbon resistance b, a power screw k for the resistance being driven by the working motor a through coned pulleys d, e. If the speed of the motor a varies, relative motion between the screw k, and the casing of the resistance occurs, and the resistance b in the motor field circuit is varied to bring the speed of the motor a back to its proper value. The machines h may be synchronous machines designed to run synchronously as reaction machines. In a modification, Fig. 2 (not shown), the rotor of the motor h is driven from the motor a, and its " stator " is arranged to actuate the resistance b. The invention is stated to be applicable to a mechanical synchronization regulating device using a leading shaft, and differential gear.

Title: Improvements relating to the regulation of current supplied from an a.c. source
IPC: G05F1/32
Filed: 1947-06-26
Abstract: 637,663. Rectifying; automatic control systems. HARMER, H. M. June 26, 1947, No. 16883. [Classes 38 (ii) and 38 (iv)] [Also in Group XXXIX] The power output of a system with a regulated direct voltage or current output is amplified by a transductor which comprises two series connected secondary windings each on its separate magnetic circuit and supplying the load from the D.C. output, and one common or two series or parallel connected primary windings, which supply the load from an A.C. source through a rectifier, the proportion of load current supplied from each source remaining constant. Fig. 2 shows the load supplied at 4 through series connected secondary windings S of transductor 1 from terminals 2 to which a regulated direct voltage or current source is connected. The load is also supplied from an A.C. source 3 through rectifiers 5 and parallel connected windings P of transductor 1. The transductor is so designed that the A.C. current is 2n times the D.C. current, where n is the turns ratio between the A.C. and D.C. windings. As the load current drawn from 4 varies, it remains proportional to the input D.C. current at 2, the voltages at 2 and 4 remaining equal. The proportions of the load current supplied from the two sources-A.C. at 3, D.C. at 2- thus remain constant. The voltage drop in the D.C. windings S may be compensated by a supply from the A.C. through transformer 8 and rectifier 9, the characteristic may be improved at low loads by condenser 10 and the inductance of transformer 7, and the amplification factor may be varied by a variable resistance 11 connected across the windings S. To vary the circuit characteristic the resistance 11 may be a carbon pile regulator with its coil connected across the output terminals 4. An arrangement is described for energization by three-phase A.C., Fig. 5 (not shown). Several amplifier stages may be connected in series. A constant voltage, current limited supply may be obtained by connecting in series the output terminals of two amplifiers connected respectively to circuits with voltage and current regulation respectively. Constant current may be obtained from a D.C. source through a barretter, from an A.C. source through a barretter and rectifier, Fig. 4 (not shown), or from circuit as described in Specifications 521,314 and 637,518. Constant voltage may be obtained at 21, Fig. 3, from A.C. through a barretter 11<1>, rectifier 18 and transformer 12, the voltage of which transformer is locked by a second circuit comprising rectifier 14, neon tube 16 and, if desired, terminals 17, or from circuits such as those described in Specifications 493,362, 515,207, 524,565, 554,467, 555,004, 573,185, 637,518 and 637,664.
