Abstract

296,493. Sadd, J. A. June 14, 1027. Elastic-diaphragm pressure gauges for use with aneroid barometers and the like has the surface wholly or in part corrugated in two directions at right angles. In the form shown the corrugated part c<1> is bounded at its inner and outer parts by flat annuli a, b. The corrugations are preferably curved to a sine wave formation.
