Abstract

1294907 Automatic phase control systems COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT 28 May 1970 [29 May 1969] 25782/70 Addition to 1,133,009 Heading H3A An arrangement for automatically controlling the relative phase of two high-frequency transmitters 210, 220 according to claims 1, 2 or 3 of Specification.1,133,009 is modified by having as the device for momentarily suppressing automatic phase control a short circuit arrangement 230-234 coupled to the output of the phase comparator 203-206 for earthing the output terminal 209 when the absolute value of the phase comparator output signal exceeds a predetermined value. The device for momentarily breaking the phase control may comprise a measuring device 230 of the needle type, the deviation of the needle indicating the direction and amplitude of the relative phase shift, photoelectric devices 233, 234 and relay members 231, 232 short-circuiting the control voltage applied to adjustable phase shifter 202 when the relative phase shift exceeds a predetermined amount.
