Abstract

817,989. Lift control systems. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 3, 1957 [May 7, 1956], No. 14156/57. Drawings to Specification. Class 78 (3). The electromechanical selector switches 20- 25 and M of the lift control system described in Specification 396,629 are replaced by sets of stationary contacts which are successively energized in accordance with the position of the car by static circuit elements which respond to operation of a notching relay carried by the car and operated by inductor plates mounted in the shaft. The Specification describes in detail circuits for selectively energizing the contacts, and the manner in which the device operates in the system of Specification 396,629.
