Abstract

451,379. Pressure gauges. NEGRETTI, H. N., NEGRETTI, P. E., ZAMBRA, M. W., and IBBOTT, H. W., 38, Holborn Viaduct, London. May 28, 1935, No. 15553. Drawings to Specification. [Class 106 (ii)] A flexible corrugated metal diaphragm for a pressure gauge or the like is made of elongated form with the corrugations in substantially closed curves following the form of the periphery of the diaphragm. In one form described in the Specification, the diaphragm has straight parallel sides and rounded ends.
