Patent number: 9989341Abstract: Stun grenades may include a fuze configured to ignite a delay material secured to a housing including a delay chamber in which the delay material is located. A handle of the fuze may be located over a final payload chamber of the series of payload chambers, payload material in the final payload chamber being configured to ignite after ignition of payload material in each other payload chamber of a series of payload chambers. Methods of assembling stun grenades may involve positioning an obstruction in a port extending between a delay chamber and a payload chamber of a series of payload chambers surrounding the delay chamber in a housing. A delay material may be packed in the delay chamber. The obstruction may be removed, and a payload material may be positioned in the payload chamber and the port.Type: GrantFiled: April 21, 2015Date of Patent: June 5, 2018Assignee: Orbital ATK, Inc.Inventors: Steven M. Robbins, Royce C. Duke, Reed J. Blau, James R. Hodgson, Dixon Brockbank

Patent number: 9919173Abstract: 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. In one embodiment, the system includes multiple gas generators and is configured to ignite the respective gas generant of each gas generator in a predetermined, time based sequential order. For example, the gas generant of each gas generator may be ignited in a sequential order at specified time intervals. Methods of extinguishing fires are also disclosed.Type: GrantFiled: March 11, 2013Date of Patent: March 20, 2018Assignee: Orbital ATK, Inc.Inventors: Reed J. Blau, James D. Rozanski, Richard M.

Patent number: 9199886Abstract: 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.Type: GrantFiled: December 4, 2009Date of Patent: December 1, 2015Assignee: Orbital ATK, Inc.Inventors: Jerald C. Hinshaw, Daniel W. Doll, Reed J. Blau, Gary K. Lund
