Abstract

537,119. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and MONTGOMERY, W. A. Dec. 7, 1939, No. 31703. [Class 40 (v)] In a time-base circuit for feeding the deflecting coils of a cathode-ray tube, frequency and phase distortion due to the leakage inductance of the output transformer are reduced by feeding back to the input circuit a voltage derived from the deflecting current, by a transformer T2, the primary of which is in series with the deflecting coils L2 A preceding amplifier V may be used to reduce frequency distortion at the lower frequencies Specification 535,387 is referred to.
