Publication number: 20080237194Abstract: An arc extinguishing composition including an arc-quenching metal hydrate (herein defined as a metal compound that produces water vapor (H2O) when in contact with an electrical arc), and one or more binders. The compositions contain an arc-quenching metal hydrate compound, such as Mg(OH)2, with or without a second arc-quenching compound, such as melamine, and these metal hydrate-containing compositions are used in a method of extinguishing an arc by disposing the molded compositions along a path of an electrical arc, for contacting the arc.Type: ApplicationFiled: June 12, 2008Publication date: October 2, 2008Applicant: S & C ELECTRIC CO.Inventors: Jeffrey A. Moore, Keith W. Benson

Patent number: 7407598Abstract: The present invention is directed to pyrotechnic aerosol fire suppression compositions that burn rapidly, but coolly. The rapid burning of the compositions of the present invention produces a voluminous flame-suppressive aerosol that is useful in suppressing and/or extinguishing both small and large fires. The compositions of the invention contain at least one oxidizer and a fuel component comprising at least one organic acid salt, which combination produces a rapid burning composition that burns at low temperatures with little or no flame.Type: GrantFiled: April 30, 2004Date of Patent: August 5, 2008Assignee: Goodrich CorporationInventors: Philip L. Posson, Mark L. Clark

Patent number: 7343981Abstract: The present invention relates to methods of using at least one fluoroketone selected from monobromoperfluoroketones, monohydromonobromoperfluoroketones, (perfluoroalkoxy)monobromoperfluoroketones, (fluoroalkoxy)monobromoperfluoroketones, and monochloromonobromoperfluoroketones for i) extinguishing fire by applying to the fire such a fluoroketone, ii) preventing fire in an air-containing enclosed area containing combustible materials by introducing into the area such a fluoroketone and maintaining the fluoroketone in an amount sufficient to suppress combustion of combustible materials in the enclosed area, and iii) reducing or eliminating the flammability of a flammable working fluid, by mixing between about 0.1 to about 99 percent by weight of such a fluoroketone with the flammable working fluid.Type: GrantFiled: June 18, 2004Date of Patent: March 18, 2008Assignee: E.I. du Pont de Nemours and CompanyInventors: Mario J. Nappa, Velliyur Nott Mallikarjuna Rao, Allen C. Sievert

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
