Abstract 402,121. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, both in London, and PLAISTOWE, D. L., 21, Oakleigh Park Drive, Leigh-on-Sea. May 25, 1932, No. 14877. [Class 40 (v).] A direction-finding or navigation system comprises a plurality of television transmitting stations including at least one master station A which generates and transmits synchronising signals and picture signals characteristic of the station, and at least one sub-station, which receives the synchronising signals and uses them to synchronise mechanism BND for transmitting picture signals characteristic of the sub-station. Neon tubes ANT1, ANT2, BNT1, BNT2 and extra spirals on the scanning- discs AND, BND monitor the local transmission and the signals from other stations. At a receiving station C, a directional receiver CTR builds up a television picture from received signals, and a non-directional receiver CSR receives synchronising signals to synchronise the mechanism CND which builds up the picture.
