  • Patent number: 9199886
    Abstract: Gas-generating compositions and methods for their use are provided. Metal complexes are used as gas-generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite amine, metal nitrate amine, and metal perchlorate amine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas-generating compositions and to permit efficient combustion of the binder. Such gas-generating compositions are adaptable for use in gas-generating devices, such as automobile air bags.

  • Publication number: 20150203415
    Abstract: A reactive material that includes at least one of a fuel, an oxidizer, and a class 1.1 explosive and is formulated for use in a reactive material projectile. The reactive material is formulated to provide at least one of an overpressure of greater than approximately 9 pounds per square inch at a radial measurement of 12 inches from a point of impact on a target, a hole greater than approximately 2 square inches at an optimum penetration level in a target, and pressure, damage, and a flame when the reactive material bullet impacts a target. The fuel may be a metal, a fusible metal alloy, an organic fuel, or mixtures thereof. The oxidizer may be an inorganic oxidizer, sulfur, a fluoropolymer, or mixtures thereof. A reactive material projectile having the reactive material disposed therein is also disclosed.

  • Publication number: 20140048291
    Abstract: A fire suppression system for producing an inert gas mixture having a minimal amount of carbon monoxide, particulates, or smoke. The inert gas mixture may be generated by combusting a gas generant. The gas generant may be a composition that includes hexa(ammine)-cobalt(III)-nitrate. The fire suppression system also includes a heat management system to reduce a temperature of the inert gas mixture. A method of extinguishing fires is also disclosed.
