Abstract

398,512. Television. BANKS, G. B., WILSON, J. C., and BAIRD TELEVISION, Ltd., 133, Long Acre, London. March 15, 1932, No. 7654. [Class 40 (iii).] In a television system in which a sound accompaniment is transmitted with the picture, but over a separate channel, the signals for synchronization of the picture receiving apparatus are transmitted over the sound channel. The synchronizing signals, which may be produced by a small electric generator on the shaft of the scanning device, are, at the receiver, filtered out and applied to synchronize the reconstituting device. The synchronizing signals may be fed in parallel to the sound reproducing device through a rejector circuit, eliminating the synchronizing impulses, and to a tuned circuit incorporating a power valve in the output circuit of which are the field coils of a phonic-wheel motor. Alternatively the synchronizing signals may be used to control a relaxation oscillator which drives the scanning apparatus of the receiver. The synchronizing signals may contain two components for effecting the scanning movements in a cathode-ray receiver. The synchronizing frequency may form the carrier for the sound signals.
