Abstract
814,735. Fire extinguishing systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 12, 1956 [Sept. 15, 1955], No. 26436/56. Class 47 In a combined ventilation and fire extinguishing system, a stream of fire extinguishing liquid is mixed with the ventilating draught to form a fire extinguishing mist or fog which is projected into the space being ventilated, e.g. a ship's cabin or other location. Ventilating air flows from an air supply pipe 3, Fig. 1, into a port 19 in a casing 8, Fig. 2, and through a passage 9, to outlet perforations 24 which project the flowing stream fanwise into the cabin 1. A fire extinguishing liquid supply passage 10 in the casing 8 is normally closed by a frangible plate 11. At a predetermined temperature a fusible metal link 15 releases a spring- loaded pin 13 which fractures the plate 11 allowing liquid in the passage 10 to flow into the chamber 9 and mix therein with the air entering the port 19 to form a mist or fog which is projected into the cabin 1 through the perforations 24. Downward movement of the pin 13 is limited by a collar 20 thereon having serrations 22 which prevent obturation of the passage 10. Ventilating air is also introduced into the cabin through an air diffuser 2 connected to the air supply pipe 3. Temperature controlled means may be provided for automatically shutting off the passage of air through the diffuser when the temperature in the cabin reaches a predetermined maximum. The air entering through the diffuser entrains and mixes with the air in the cabin, and in the case where no provision is made for shutting off the passage of air through the diffuser, the diffuser may be so disposed that when the mist or fog is projected into the cabin, some of it will be projected at the diffuser and be entrained with the air entering through the diffuser. Vitiated air normally passes out through an outlet 7 which may be automatically closed when the fire extinguishing means comes into operation. In another arrangement, both the forced draught ventilating air and the liquid are fed to a nozzle so that the liquid is atomized by the air passing through the nozzle.
