Abstract

581,996. Radiolocation. COCKCROFT, J. D., CHICK, D. R., EASTWOOD, W. S., and OXFORD, A. J. H. Dec. 11, 1942, No. 15190/44. Divided out of 581,980. Drawings to Specification. [Class 40 (v)] In a radiolocation or other system of the pulse repetition type, means for selecting at will one signal to the exclusion of others comprises means for varying the timing of a source of recurrent signal-selecting impulses, a cathode ray oscillograph to indicate the relative timing of the impulses and the desired signal, and an electronic switch (e.g. a valve) controlling a channel conveying the signals to a point of utilization, the switch being responsive to the signal-selecting impulses. The arrangement described is identical with part of that described in Specification 581,980.
