Abstract
614,557. Cathode-ray oscillographs. FORBES, I. S., and HARROD, K. W. G. May 20, 1946, No. 15259. [Class 37] [Also in Group XL (c)] The time base of a cathode-ray tube used for indicating signals from a rotating member, driven by an A.C. motor, is subjected to corrections dependent upon frequency fluctuations of the motor supply from a predetermined value. In one embodiment, a radar directionfinder 3, of the spinning radio-goniometer type, is driven by a synchronous motor 2 supplied from A.C. mains 1, the signals passing through a deflection amplifier 10 to a cathode-ray tube 11. The voltage supply to the charging circuit of the time base 6 passes through a frequency discriminator 8, whose output voltage varies with the mains frequency, and through a rectifier 9.
