Title: Improvements in or relating to high frequency amplifiers, radio transmitters and the like
IPC: H03H7/48
Filed: 1946-12-06
Abstract: 631,744. Automatic phase-control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., GREEN, E., and STOKES, V. O. Dec. 6, 1946, No. 36178. [Class 38 (iv)] [Also in Group XXXVI] In a radio transmitter or amplifier of the kind in which a drive oscillator feeds a load through a plurality of separate channels, phase agreement at the final stages is ensured by detecting any phase difference and utilizing the resultant voltage to control the tuning of one or more circuits in the channels. As shown, the drive oscillator 1 feeds the load 6 through two channels 2, 3 each including amplifiers and/or frequency-multipliers. A phase discriminator 11 compares the phases of the two inputs to the load 6, and voltages representative of the phase difference are applied from resistors R2, R2<1> to the grids of reactance valves V1, V1<1> in such sense as to vary the tuning of tuned circuits L3, C3, L3<1>, C3<1>, in opposite directions, and to bring the two outputs into correct phase relation. The anodes of the reactance valves are maintained in phase quadrature with their grids by virtue of the resistors Rx. One of the reactance valves may be omitted, and the two control voltages may be applied to grid and cathode of a single reactance valve (Fig. 4, not shown). When several channels are employed, one may be regarded as a standard, and the output phases of each of the other channels may be compared with that of the standard, and the error voltages applied to the grids of the.corresponding reactance valves. The phase discriminator of Fig. 2 comprises a circuit L1, C1, coupled to one load input and in tune at the working frequency, and a second out-of-tune circuit L2, C2, coupled to the other load input. The circuit L1, C1, is connected in push-pull to the anodes of two rectifiers V2, V2<1> and the circuit L2, C2 is coupled in parallel to these anodes by connecting it between earth and the mid-point of the coil L1. When the load inputs are in phase, the voltages across the respective circuits are in quadrature and the currents in the load resistors R2, R2<1> are equal. When the load inputs are out of phase, the quadrature relation is upset and the rectified currents through the resistors become unequal, one rising and the other falling. In a. modified discriminator (Fig. 3, not shown), triode rectifiers are employed, with the circuit L1, C1 centretapped to earth and connected in push-pull to the anodes, with the circuit L2, C2 connected in parallel between earth and the two grids, and with the load resistors R2, R2<1> connected in the cathode leads. A monitoring circuit comprising an additional tuned circuit associated with a rectifier and meter may be equally but oppositely coupled to the load inputs so as to indicate the phase difference between them. Visual or oral indicators may be brought into operation when a pre-set level of phase difference is exceeded, and automatic circuit-breakers may be arranged to operate when a higher level of phase difference is reached.

Abstract: 1506008 Data transmission PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 Sept 1975 [12 Sept 1974] 37030/75 Heading H4P Digital data signals from a source 1 controlled by a clock 2 with a frequency f 1 , are sampled at the frequency f 1  by a device 4 having its output connected to a digital filter 3, each signal element being sampled once in order to ascertain whether it is a binary "1" or a binary "0". The filter 3 has a pass-band characteristic and is arranged to convert the signal samples at frequency f 1  into signal samples at a frequency f 2 , the latter being twice the frequency of a carrier wave derived from a source 6. The carrier wave is also sampled, at the frequency f 2 , and each signal sample at frequency f 2  is multiplied in a modulator 5 by a carrier wave sample. As the carrier wave samples, because of the frequency at which they are derived, can be represented in numerical form by the numbers + 1, - 1, + 1, -1, ..., the modulation process thus comprises an alternating inversion of the signal samples derived from the filter 3. The output from modulator 5 is applied over a D/A converter 7 and a filter 8 to a transmission line 9, and the Specification explains, with reference to Figs. 2a to 2d (not shown, how the information content of the original input signals is retained in the transmitted signal. The Specification states that the modulating and filtering arrangement may be applied to FSK, PSK and AM systems.
