Abstract

1369788 Counter systems PRODUCTION ENG RESEARCH ASSOCIATION OF GREAT BRITAIN 21 Sept 1971 [22 July 1970] 35452/70 Heading G4D A counter associated with a power press or similar machine is arranged to count only working strokes and not idle strokes. A strain gauge is attached to the machine to provide an electrical signal. The magnitude of the signal during a working stroke exceeds the reference level set in a threshold unit but at all other times lies below the reference. The output of the threshold unit controls an electromagnetic counter. The threshold unit includes a variable resistor providing a coarse calibration control.
