Abstract
492,665. Supply systems for vacuum and low -pressure discharge apparatus. BAIRD TELEVISION, Ltd., and MERDLER, L. R. March 23, 1937, No. 8515. [Class 38 (iv)] In a television receiver the cathode-ray tube 1 or other electronic picture re-constituting device has its control electrode supplied with a bias voltage from a power pack 3 which is connected in series in the anode-cathode circuit of the tube with at least part of a second power pack 4 which supplies the anode potential whereby the anode to cathode potential is increased. The biassing source 3 for the modulating electrode also supplies the receiving valves or scanning oscillators. The power pack 3 for the modulating electrode is connected to a potentiometer 2 from which appropriate tappings are taken to the cathode and modulating electrodes so that part of the voltage of the source 3 is added to that of the pack 4 in the anode to cathode circuit.
