Abstract

655,859. Diaphragms. BARKER, A. C. July 26, 1948, No. 19914. Drawings to Specification. [Class 40 (iv)] A conical diaphragm has a spiral corrugation, or a series of concentric circular corrugations; the distance between successive turns of the corrugation, or between successive corrugations, increases exponentially with the distance from the centre of the diaphragm. The profile of the corrugation may be symmetrical or asymmetrical. In the latter case the shorter side of the groove is approximately parallel to the axis of the diaphragm. A central portion of the diaphragm may be uncorrugated.
