Abstract

624,603. Automatic phase control systems. WILLIAMS, F. C., and MOODY, N. F. June 22, 1945, No. 1379/48. Divided out of 624,559. Drawings to Specification. [Class 38 (iv)] [Also in Group XL (c)] The subject matter of this Specification is substantially the same as that described in Specification 624,559. The claims relate to circuit arrangements for providing a control voltage when the relative timing of a recurrent input signal and a locally generated recurrent signal is such that the two signals co-exist for at least part of their duration comprising means for generating a local signal consisting of two substantially square waveforms having coincident front edges and different widths, means for obtaining a current proportional to the degree of co-existence of the input signal with one of said square waveforms and for obtaining a second current in opposition to said first current and proportional to the degree of co-existance of the input signal with the second of said square waveforms and means for deriving a control voltage in accordance with the magnitude and sense of the resultant of said two currents. Specifications 582,758, [Group XL], and 624,558, [Group XL (c)], also are referred to.
