Abstract

768,277. Electrical measuring systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 11, 1955 [Oct. 11, 1954], No. 29261/54. Class 40 (1). [Also in Group XXXVII] In a motor control system (see Group Group XXXVII), the slider 5 of a potential divider is automatically maintained in the position in which its voltage balances that of a tachometer generator 2 coupled to the driving motor. In a predetermined position of the apparatus driven by the rotor, switch 3 cuts-out the - tachometer generator and the slider is driven at uniform speed to its lowest position in which it completes a circuit for stopping the motor. The time interval between arrival at the predetermined position and operation of the stopping circuit thus depends on the speed of the driving motor. The potential divider may have a non-linear law appropriate to the inertia of the driven apparatus. The stopping circuit is completed without operation of switch 3 if the speed becomes excessive.
