Abstract

1,252,034. Counters. O. H. DRAGER [trading as DRAGERWERK, HEINR. & BERNH. DRAGER], 4 Aug., 1969, No. 39006/69. Heading G4D. Pump cycles are counted by translating each fall. in pressure at 4 into a downward movement of diaphragm-8 and pin 10 to advance a ratchet wheel 11 and numeral disc 12. The casing has a window (14, Fig. 2, not shown). The head.4 may be connected directly to the pump or by a T- junction to a pipe 3 leading to the pump. The pump may be in gas detecting or measuring apparatus or dust collecting or measuring apparatus. Resetting is effected by repeated operation of pin 10.
