Title: Improvements in or relating to electric motor control systems
IPC: H02P7/00
Filed: 1948-02-11
Abstract: 643,772. Automatic control systems for D.C. motors. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. Feb. 11, 1948, No. 4045. [Class 38 (iv)] [Also in Group XXXVII] An automatic control system for a reversible D.C. motor supplied from gridcontrolled rectifiers or from a motor generator set includes a resistance capacity circuit, the time constant of which limits the rate of rise of starting current. The motor 1 is supplied by full-wave connected rectifiers 3, 4, the output of which is controlled by phase shift of the grid voltage by a phase-shifting network 17 including a saturable reactor. 20 controlled by a valve 21 which, at low values of load current, is controlled by a valve 23 in accordance with the resultant of the rectifier output voltage and an opposing reference voltage derived from a potentiometer 30 and a battery 31. When the load current exceeds a predetermined value, valve 21 is controlled by a valve 24 in accordance with the resultant of a voltage proportional to load current and a variable reference voltage. The load current is measured at 37 by means of saturable reactors controlling an A.C. supply in accordance with load current, or by means of current transformers in the rectifier anode circuits. The reference voltage, obtained from battery 43 and potentiometer 41 is applied to a condenser 38 through a resistor 49. Condenser 38 is short-circuited by series connected contacts 39, 40 on the forward and reverse motoring contactors 15, 16 when the contactors are not energized. Thus the reference voltage is zero and the rectifier output is zero. On energizing either contactor, contact 39 or 40 opens, and the reference voltage rises at a rate determined. by the time constant of resistor 49 and condenser 38. This is so arranged that the rise in load current is limited and transient overcurrents on starting or reversing are substantially reduced. Specification 643,771 is referred to.

Filed: 1941-04-02
Abstract: 562,948. Bomb sights. SLONIMSKY, L. April 2, 1941, No. 4441. [Class 92 (ii)] A bomb sight for aircraft comprises means for setting a sighting telescope from data derived from the use of a coincidence type range finder, a connection being provided between the range finder and the telescope for automatically and continuously adjusting the setting of the telescope to. the release angle in accordance with the setting of the range finder. Fig. 3 shows in plan a range finder 10 of the coincidence type combined with a telescopic bomb sight 20 mounted for graduated movements in elevation and azimuth with respect to a platform 21 to set the sight for release angle and for drift. The settings are determined by the adjustments of the range finder which is mounted as in Fig. 1 with its base across the wing span. To determine automatically the adjustment of the bomb sight for the speed of the aircraft, the adjustment of the range finder mirrors 24 effected by a motor 29 through gear 30, screw 28 and rods 26, is conveyed to the bomb sight by a circuit including a variable rheostat 31 and an arcuate solenoid 32. When the current to the motor 29 is varied by the rheostat to keep the range finder adjusted to suit the speed of the aircraft, the current through the solenoid acts on the armature 33 to adjust the bomb sight.

Abstract: 379,626. Reproducing or recording music & c . . TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin.-(Assignees of Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) Feb. 15, 1932, No. 4500. Convention date, Feb. 13, 1931. Drawings to Specification. [Class 40 (iv).] Non-linearity of response in microphones, amplifiers, loud-speakers, recording or other apparatus used in the electrical transmission of sound, gives rise to combination frequencies (sums and differences) forming dissonant intervals with primary frequencies. The frequency separation between a combination frequency and a primary frequency giving maximum dissonance increases with the primary frequency. The number of possible combination frequencies is reduced by splitting the frequency band into two non-overlapping sub-bands which are separately treated throughout the whole or part of the transmission system, and according to the invention a frequency lying between 100 and 750 cycles is selected as the most favourable point of subdivision of the band. If the whole range from 32 cycles upwards is to be transmitted, the separating frequency should lie between 150 and 450 cycles, but if 50 cycles is the lowest transmitted frequency it may lie between 150 and 700 cycles. The whole transmission system from microphone to loudspeaker may be subdivided, acoustic filters being used for the input to the two microphones, or the subdivision may occur immediately preceding an amplifier or loudspeaker or other distorting stage in the transmission. In optical recording, separate traces of the two sub-bands may be made on the same film, the traces being treated separately in reproducing if distortion occurs in the amplifier or loud-speaker.
