Title: Improvements in systems for radio navigation
IPC: G01S1/08
Filed: 1946-07-19
Abstract: 648,246. Phase measurements. SOC. FRANCAISE RADIO-ELECTRIQUE. July 19, 1946, No. 21709. Convention date, May 5, 1944. Drawings to Specification. [Class 37] [Also in Group XL (c)] In a radio beacon system (see Group XL (c)), means are described, Fig. 4 (not shown), for measuring the phase difference between two sinusoidal waveforms of equal frequency. Phase quadrature components are derived from each waveform and applied to the deflection members of a cathode-ray tube in such a manner that each waveform in the absence of the other would rotate the electron beam at the frequency of the waveform, the directions of rotation produced by the two waveforms being opposite so that the resultant effect of the two waveforms is to oscillate the beam along a diametrical line which is inclined with respect to a reference line by an angle equal to half the phase difference. The Specification as open to inspection under Sect. 91 describes an embodiment, Fig. 7 (Cancelled, not shown), in which the two waveforms are combined in opposition and applied to a telephone receiver, a phase shifter being inserted in the path of one waveform so that the phase shift required to produce a zero resultant output is equal to the phase difference. In Fig. 8 (Cancelled, not shown), one waveform produces a circular trace on a cathoderay tube and the other waveform is converted into a pulse train and applied to intensity modulate the tube or to cause a radial deflection, the angular position of the resultant indication on the trace being equal to the phase difference and in Fig. 9 (Cancelled, not shown), both waveforms are converted into pulse trains one set of pulses being applied to strike a neon which is extinguished by the other set so that the duration of the current pulses passed by the neon and hence the amplitude of the average current is a measure of the phase difference. This subject-matter does not appear in the Specification as accepted.
