Title: Improvements in or relating to high frequency selective signalling systems utilisingpower lines
IPC: G08C19/48
Filed: 1933-04-20
Abstract: 417,205. Wired wireless systems; copying telegraphy. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald, A. S.; Warwick Road, Wynnewood, Pennsylvania, U.S.A.) April 20, 1933, No. 11590. Convention date, April 20, 1932. [Classes 40 (iii) and 40 (v).] A glow-discharge tube, which is conductive only during the maximum-voltage periods of an applied L.F. cycle, is utilized to control the emission from a high-frequency oscillator. Fig. 1 shows the arrangement applied to the selective operation of relays associated with a power - supply system. The high - frequency transmitter 2 is only operative for a timeinterval represented by b, Fig. 4, of the applied E.M.F. shown in Fig. 2. The lower-frequency voltage is supplied from a secondary winding 11 through a primary winding 9 connected across the three-phase power line 1. At the receiver 3<1>, when the secondary winding 121 is alined with the winding 11, the relay 4<1> is operated by the conjoint action of the current in the transformer 141 and in the transformer 61 fed from the transmitter 2. On the other hand the relay 4 of the receiver 3 is not operated because, owing to the different alinement of the winding 12, one of the two currents required to operate the relay is 90‹ out of phase. The Specification as open to inspection under Sect. 91 describes the application of the invention to a copying telegraph in order to produce a sharply-defined response, for a comparatively slowly-varying level of light-intensity, corresponding say to greyish typewriting on a white paper. The facsimile signals from a source 24, Fig. 5 (Cancelled) are rectified at 22 and are fed to a glow-discharge tube 15, which, at a predetermined voltage, spills over and throws a heavy negative bias on the amplifier 21 from a resistance 28. This in turn interrupts the current through a resistance 17, which, by removing the negative bias from a valveoscillator 2, brings the latter sharply into action. The discriminating effect of the glowdischarge tube 15 may also be used to prevent undesired line noise from affecting the transmitter 2. This subject-matter does not appear in the Specification as accepted.
