Abstract

928,023. Lift control systems. WESTING- HOUSE ELECTRIC CORPORATION. April 20, 1961 [April 25, 1960], No. 14242/61. Drawings to Specification. Class 78 (3). In a lift control system, the call registering means, the landing selector means, the direction determining means, the stopping means and the door control means each comprise a plurality of electrical static 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 a system, incorporating NOR, OR, MEMORY and DELAY elements, for a lift serving five floors, in which the components of the control system associated with each floor are mounted on a board corresponding to the floor supported withdrawably in a rack, Fig. 7 (not shown) together with a terminal circuit board and a relay board. Each board is provided with a printed circuit board into which the static elements are plugged.
