  • Publication number: 20140158250
    Abstract: A gas storage container, such as a gas cylinder, is filled with a gas mixture comprising a first gas and a second gas under pressure by feeding a liquid/solid mixture comprising liquefied first gas and solidified second gas into the gas storage container; closing the gas storage container to the passage of gas into or out from the container; and allowing said liquefied first gas and said solidified second gas to become gaseous within said closed gas storage container. Such a process is easier and more energy efficient as compared to direct compression processes, and is safer and results in less wastage as compared to direct liquid injection processes.

The inert gas may be nitrogen, carbon dioxide, argon, neon or helium or mixtures of any two or more of them. The suppressant and the inert gas are fed under pressure to an output unit (34) comprising a mixing chamber in which the liquid and the gas impinge to produce a mist of the liquid suppressant of very small droplet size which is entrained in the pressurised gas together with vapour from the liquid, the so-entrained mist and vapour and the gas being discharged by a nozzle (44) into an area to be protected. The mist and vapour are therefore carried by the entraining and transporting high pressure gas into regions of the areas to be protected, enabling a total flooding capability.

  • Patent number: 6776920
    Abstract: A gel is produced by magnetically treating and mixing two solutions and in one embodiment subsequently introducing carbon dioxide gas. The first solution is comprised of water and sodium bicarbonate, and the second solution is comprised of water and sodium silicate. The first solution is passed through a positively charged magnetic field, and the second solution is passed through a negatively charged magnetic field. The two solutions are then mixed together to form a gel. The resulting gel has excellent fire-fighting capabilities because of its high heat absorption and emissive qualities. The gel can also be used to aid in the removal of surface coatings.

  • Patent number: 6740250
    Abstract: A biodegradable, non-toxic firefighting concentrate composition. The preferred compositions include a mixture of a C14-C18 5 mole ethoxylated tallow amine, 2 mole ethoxylated coconut amine, and 5 mole ethoxylated coconut amine, wherein the blend is neutralized with a C6 carboxylic acid; an aliquot of 33 parts is added to 3 parts of a 2 mole ethoxylated linear alcohol having 6 to 16 carbon atoms, and enough water to bring the total weight percentage to 70%. Ten to fifteen parts of sodium lauryl sulfate is added and the balance of water is added to bring the total up to 100%. The composition is also effective when mixed with glycol dimethyl ether, the incorporation of a filming protein based agent, dye, or foam forming materials. In addition, the composition is useful with soil bacteria for remediating soil contaminated with hydrocarbon fuel and for facilitating fuel dispersion and degradation within bacterial-action sewage systems.

  • Patent number: RE40651
    Abstract: A class of fire suppressant compounds which have labile bromine atoms bound to atoms other than carbon have been discovered to be more effective at suppressing fires than Halon 1211 and Halon 1301. Moreover, this class of fire suppressant compounds hydrolyze or oxidize rapidly in the troposphere and as a consequence thereof, they have minimal ozone depletion potential.
