Abstract

1,046,558. Radio navigation. WAYNE KERR CO. Ltd. June 15, 1965 [July 22, 1964], No. 29600/64. Addition to 1,011,513. Heading H4D. [Also in Division G1] In the I.L.S. apparatus described in the parent Specification (see Division G1) improved automatic control for the phase of the 120 c/s. reference signal is effected in accordance with the integral of the output of a phase-sensitive detector, or a voltage-controlled oscillator (which may be a multivibrator) is provided.
