Abstract

961,144. Temperature-responsive actuating- elements. J. E. LINDBERG. Feb. 21, 1961 [Feb. 29,1960], No. 6367/61. Drawings to Specification. Heading G1D. [Also in Divisions B7, G4 and H2] A temperature alarm (see Division G4) uses a pressure-sensitive switch which responds to a sudden increase in gas pressure created within a housing at a critical temperature, generally as described in Specification 961,143.
