Abstract
519,789. Fire-extinguishing. CARDOX (GREAT BRITAIN), Ltd. (Cardox Corporation). Oct. 1, 1938; No. 28604. [Class 47 (ii)] Liquid carbon-dioxide at a low temperature; preferably below. 32‹F., is charged by a pipe 20 into an insulated container 18 of large capacity and strong enough to resist the vapour pressure corresponding to this low temperature. During storage, it is maintained at a constant low temperature by means of a refrigerating plant 21 having its coil 22 in a dome 23 above the liquid level in the container and by means of a blow-off valve 24 operative if the pressure in the container rises. Thus, the liquid carbondioxide, drawn off by a pipe 19, is always discharged, when required, at a low temperature and pressure; and, consequently, under good snow-forming and cooling conditions. The pipe 19 is connected to various discharge devices suited to particular fire risks. As shown, a room 6 is provided with a sprinkler system 7, 8 a' hose and nozzle 9, 10 and a fixed pipe 12 to an enclosed danger point 11, and a heap of combustible material 13 is fitted with fixed nozzles 14 and a hose 17 with a perforated spear 16.
