Abstract

1,182,682. Control of D.C. motors. A. TANNER, E. CHOSID, L. TANN, D. TANN, G. TANN and H. TANN, [trading as TANN CO.] 13 Feb., 1967, No. 47542/69. Divided out of 1,182,681. Heading H2J. The subject-matter of this specification is identical with that described in Specification 1,182,681 but the claims are concerned with an electric motor speed control device comprising cyclical energizing means for energizing an electric motor with cyclical electric power pulses, and timing means responsive to said cyclical energizing means for independently controlling the length of time of one phase of said cycles in a manner to regulate the speed of said motor, said cyclical energizing means being responsive to the speed of said motor, to vary the frequency of said cycles in proportion to the speed of the motor, said timing means being activated by said cyclical energizing means at a predetermined point in each cycle and thereafter providing a timing control independent of the speed of said motor.
