Abstract

459,400. Television. FARNSWORTH TELEVISION, Inc., 505, Crocker Building, 620, Market Street, San Francisco, U.S.A. Nov. 2, 1935, No. 30344. Convention date, Nov. 5, 1934. [Class 40 (iii)] The framing saw-tooth oscillation A, Fig. 4, is combined with a square-topped wave B to produce an oscillation C which produces intercalated scanning. Alternatively, the square-topped wave may be replaced by a saw-tooth wave, the line and frame oscillators being then interlocked. The line and frame oscillators are interlocked by an interconnection of an oscillator operating on a common harmonic. Specification 423,101 is referred to.
