Abstract

907,295. Control of D.C. motors. BROOKHIRST IGRANIC Ltd. March 9, 1959 [March 10, 1958], No. 8021/59. Drawings to Specification. Class 38 (3). [Also in Group XXXV] The subject-matter of this Specification is identical with that described in Specification 907,294, but the claims are concerned with a voltage regulator system comprising means responsive to predetermined incremental values of input reference voltage for providing predetermined values of amplified output voltage, means normally automatically operable for altering said input reference voltage in predetermined steps, and means for testing the magnitude of the output voltage for each step of input voltage when said automatically operable means is inactive comprising manual means operable in steps for sequentially simulating input voltage conditions normally produced by said automatically operable means, and means for adjusting the input reference voltage for each step of said manual means thereby to preset the system for automatically providing said predetermined values of output voltage.
