Abstract

1,073,374. Transistor sawtooth circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 20, 1964 [Feb. 6, 1963], No. 4839/63. Heading H3T. [Also in Division H2] The line timebase generators disclosed in Specification 964,609 are modified by replacing the semi-conductor controlled rectifier by a transistor having a diode connected in the collector circuit. Reference has been directed by the Comptroller to Specification 964,609.
