Abstract: 1,177,208. Automatic speed control. INTERNATIONAL STANDARD ELECTRIC CORP. Aug. 1, 1968 [Aug. 2, 1967], No. 36738/68. Heading G3R. Electric motor speed control apparatus including a shift register arranged to receive as inputs a reference pulse train having a repetition frequency related to a desired speed of the motor and a feedback pulse train having a repetition frequency representing the actual speed of the motor; each pulse of the reference pulse train acting to drive a marker condition of the register one stage in a forward direction and each pulse of the feedback pulse train acting to drive the marker condition one stage in the reverse direction and includes means for interrogating the stages of the register in succession in the forward direction and means for applying driving power to the motor during a part only of the interrogation cycle beginning when the interrogation process reaches an end stage and ending when it reaches the stage in the marker condition. As shown the shift register is a 16 stage unit comprising bi-stable elements FF1 to FF16 arranged to be successively set in their "ON" condition by reference pulses in line TL1 and reset from the highest set stage by pulses in line TL2 fed from a photo-cell PC controlled by a disc D on the motor M. Afourstage binary counter FF17 to FF20 controls coincidence gates G2 to G16 which in each 160 milisecond cycle operate an "OR" gate 17 at a time, after a gate 18 operates, dependant upon the number of stages of the register that are in the "ON" condition. Provided that the bi-stable element FF1 provides a coincident pulse, the gate G18 operates a further bi-stable element 21 to energize a switch S which controls the supply to the motor and is subsequently switched off when the element FF21 is reset through gate G17 as mentioned above. The speed of the motor will depend on the time the switch S is closed during each 160 milisecond cycle and this will depend on the relative number of pulses in the two trains.
