Abstract
628,349. Pistons. CAZIOT, P., [Representative of CORBLIN, H.]. July 18, 1947, No. 19332. Convention date, Feb. 25, 1939. [Class 122(i)] [Also in Group XXVIII] A device for giving warning of damage to the diaphragm of a diaphragm pump (see Group XXVIII) consists of a diaphragm comprising three separate diaphragms f, h, g, clamped together, the outer diaphragms f, g, being whole while the intermediate diaphragm h is provided with a narrow radial slit h<1> terminating in a lug h<2> on the periphery of the diaphragm. The diaphragms f, g, are provided with similar lugs f <2>, g<2>, and on assembly the three lugs register and are connected by a tube i which depends into a vessel j containing liquid to indicate es. cape of gas or liquid through the diaphragms f, g. In a modification five diaphragms are employed two of which are slit and arranged as above to indicate separately leakage from either of the outer diaphragms.
