Abstract

536,930. Fire detecting &c. devices. ETABLISSEMENTS PHILLIPS & PAIN. March 19, 1940, No. 5133. Convention date, March 21, 1939. [Class 47 (ii)] A fire detecting device which operates extinguishing means by direct pressure comprises a charge of powder enclosed in a casing and exploded by conduction of heat through the wall of the casing. The charge 3 is carried in the heat-like end 2 of a member 1 screwed to a sleeve 7 carrying the main charge 8 of fuse powder and connected to an extincteur which it operates pneumatically when the charge 8 is ignited from the charge 3. The latter is ignited by conduction through the wall 2 which may be surrounded by rapid burning powder enclosed within a protecting cap 5 of easily inflammable material which may be provided with firing filaments 6.
