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.Type: GrantFiled: July 13, 2001Date of Patent: May 25, 2004Assignee: Hazard Control TechnologiesInventors: Michael T. Greiner, Thomas G. Legare, III

Patent number: RE40651Abstract: 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.Type: GrantFiled: July 16, 2004Date of Patent: March 10, 2009Assignee: Eclipse Aviation CorporationInventors: John H. Huntington, Peter D. Haaland
