Abstract

1473520 Lift signalling WESTINGHOUSE ELECTRIC CORP 7 May 1974 [8 May 1973] 20062/74 Heading G3N The description is similar to that of Specifications 1473518, 1473519 but the claims are directed to the use of the matrix to operate car position indicators. The indicators are in the car and/or on landings or supervisary centre. The position indicated is that of the car if it is at rest, or the first landing at which it could stop if travelling. Each matrix row represents a group of floors and each column a particular floor within the group.
