Abstract
388,370. Converting. CLAY, R. S., Eskdale, Fortis Green, London. Aug. 14, 1931, No. 22981. [Class 38 (ii).] A saw-toothed oscillation for deflecting cathode rays in television is produced by a circuit containing a self-oscillating system W, which rapidly.builds up a charge on a condenser K biasing the triode to stop the oscillation. The condenser K discharges slowly through a diode D and is in parallel with the deflecting condenser S. When the cathode rays strike the plate B, the charge formed completely discharges the condenser so that the system W may again oscillate. Specification 271,131, [Class 40 (iii), Telegraphs, Electric], is referred to.
