Abstract

864,384. Thermally - actuated valves. MATHER & PLATT Ltd. Dec. 18, 1959 [Dec. 29, 1958], No. 41846/58. Class 135. [Also in Group XXI] A frangible bulb a contains liquid, for controlling fire-extinguishing systems, and has in the liquid therein an electric resistance coil b. A detecting system causes electric heating current to flow in the coil under emergency conditions and shatter or assist in shattering the bulb by expansion or vaporization of the liquid. Expansion of the liquid is also effected when the bulb is exposed to an increased temperature. Fig. 1 shows a sprinkler application in which the bulb a holds a valve, in the end of the pipe c on its seat. When the bulb is shattered, water issues from the pipe and is spread out by the member d. Fig. 3 shows a pipe exit valve j held on its seat by a lever i and the bulb a. The lever and valve are released when the bulb is shattered.
