Abstract

485,132. Television transmitters. RADIOAKT.-GES. D. S. LOEWE. Nov. 16, 1936, No. 18215/37. Convention date, Nov. 18, 1935. Divided out of 485,119. [Class 40 (iii)] Synchronizing signals are derived by applying the deflecting potential to an amplitude filter 12 biassed to conduct just at the end of a line. The impulses are preferably taken from transformer 14, rectified at 15, and mixed with the picture signals. Alternatively they may be used to suppress the aerial current. Where magnetic deflection is used, the amplitude filter is connected in parallel to the deflecting coils or to a resistance in series with the coils.
