Abstract

455,048. Valve circuits. TINGLEY, G. R., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. April 9, 1935, No. 11008. [Classes 40 (iii) and 40 (v)] According to one aspect of the invention, synchronizing signals are intercalated in television signals by applying them to the winding 5 of a magnetron which has cathode 2, anode 4 and grid 3 and which acts as an amplifier of the television signals applied across resistance 6. The synchronizing signals inhibit the anode current. According to the other aspect of the invention, synchronizing signals are isolated from the mixed signal by applying the mixed signal to the winding of a magnetron which has a biassing current so that only the synchronizing impulses allow the magnetron to conduct or alternatively to pass current. The invention is not restricted to its application to television, but is applicable to mixing or separating other electric signals.
