Title: Regulated power supply equipment comprising parallel connected rectifiers
IPC: H02M7/08
Filed: 1947-06-13
Abstract: 631,697. Rectifying; automatic regulation. STANDARD TELEPHONES & CABLES, Ltd. June 13, 1947, No. 15646. Convention date, March 10, 1943. [Classes 38 (ii) and 38 (iv)] Regulated power supply equipment comprises rectified units L1-L4 adapted to supply in parallel a D.C. load circuit from an A.C. supply and provided with D.C. saturable reactors having regulating windings V1-V4 in their A.C. supply circuits and is characterised by a cascade connection of the rectifier units whereby the units are successively brought into use as the load increases, the rectified current from one rectifier unit passing through a regulating winding on the reactor of the succeeding rectifier unit with the exception of the last unit the rectified current of which traverses no other unit. When the voltage output of the rectifier unit L1 is higher than that of the remaining units it only supplies the load circuit but as the load increases the output voltage of the rectifier unit L2 increases (if the winding V2 has the appropriate direction of magnetization) until it equals that of the unit L1 at which point the unit L2 begins to supply current to the load circuit. Further increases in load current bring the rectifier units L3, L4 into operation. The load voltage will, however, always be determined by the voltage of the rectifier unit L1 which may' have a smaller output rating than the remaining rectifier units and which may be regulated by any suitable means, manual or automatic. The system may also be arranged to be selfregulating without the provision of additional means to the first rectifier unit by a suitable choice of voltage/current characteristic for the rectifier units so that the load voltage may increase, decrease or remain constant as the load current increases. The characteristic of each unit may be given a particular form by providing its associated 'reactor with an additional winding supplied with feed-back from the rectifier unit output. A stabilizing device S may be included so that a constant D.C. output voltage may be obtained independent of any A.C. supply voltage fluctuations which D.C. voltage may be regulated manually by tappings on a transformer TR1 or on an additional transformer placed in circuit before the reactor R1. The equipment may be provided with any known system of automatic regulation on the first rectifier unit based on, for example, the output voltage or current.

Title: Improvements in or relating to oscillation generating and modulating arrangements suitable for use in wireless signalling
IPC: H03C3/26
Filed: 1931-06-01
Abstract: 378,998. Valve generating and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Hansell, C. W. ; Port Jefferson, Long Island, New York, U.S.A.) June 1, 1931, No. 15992. Convention date, June 25, 1930. [Class 40 (v).] Frequency modulation is effected by providing two valve generators with their different frequencies determined by long-line frequency control, the two oscillators feeding a common circuit which causes them to adopt a common frequency, and the modulating currents being utilized to vary this common frequency by changing the relative intensity of oscillation cf the generators. As shown in Fig. 1, the natural frequencies of the generators 10, 12 are determined by the Lecher-wire control circuits 22, 24, and they feed a common output circuit 118. The relative intensity of the oscillations is varied by varying the grid voltage of the valves 10, 12 in phase opposition, by means of the push-pull transformer 8<1> fed by the microphone 2 or other signal producers 4, 6. The frequency-modulated output in the coil 118 feeds a carrier-suppression modulator 30, 32 supplied by a generator 34 of higher frequency, and the side bands are fed through a filter 34<1> and limiter 36 to the aerial. Alternatively, the frequency-modulated wave may be fed direct to the aerial. Inductive back coupling may be employed between the plate and grid circuits of the valves 10, 12. In the modification shown in Fig. 3, screen-grid oscillators 10<11>, 12<11> are employed, with separate tuned grid circuits 40, and a common output circuit 46. Back coupling is effected by means of long lines 22<1>, 24<1> in the form of coils, the lengths of which are an odd number of half wavelengths at their respective desired frequencies. Signal voltages are applied from the microphone amplifier 62 in phase opposition to the two grids. In a further modification, Fig. 4 (not shown), push-pull amplifiers are used in the low-frequency circuits, and the tuned output circuit 46 is connected in the grid circuit of a further amplifier, the plate circuit of which is back-coupled through longline coils such as 22<1>, 24<1> to the tuned grid circuits of the respective oscillators. The longline coils are in this case of a length equal to an even number of half wavelengths of the desired oscillation. The modulating voltages are applied in phase opposition to the screen grids of the oscillator valves. Specification 369,009 is referred to.
