Abstract
1,274,284. Automatic control of speed. T. B. WOOD'S SONS CO. May 21, 1969 [May 22, 1968], No. 51303/71. Divided out of 1,274,283. Heading G3R. The description is identical to that of the parent Specification but the claims are directed to the use of a capacitor (340) in the circuit which comprises the feedback signal with a control signal so as to nullify the effects of high frequency pulses present in the feedback signal while enabling an amplifier to respond to its average value.
