ABSTRACT:
A totalizer receives output pulses from two different meters and records them on a single data channel of a magnetic recorder. First and second memories are used alternately in successive demand intervals to store the outputs from both meters irrespective of which meter measured an event. For recording, contents of the respective memories are shifted out in alternate demand intervals. Demand interval timing signals are delayed and recorded in synchronism with the data so that the accuracy of recording is .+-. one event pulse per demand interval. Each memory acts as a summing register for both meters. Thus, the proportion of available storage allocated to each meter is varied according to the respective activity levels of the meters up to the maximum capacity of the recorder.
