Patent number: 8608878Abstract: A heat generating structure includes a substrate, a coating and a polymeric material. The substrate comprises a first material. The coating comprises a second material, different from the first material that covers at least a portion of the substrate. The coating and substrate, upon being thermally energized to their minimum alloying temperature, react in a first exothermic reaction that is an alloying reaction. The relative quantities of the substrate and coating are such that the first exothermic reaction yields a first amount of exothermic energy that is insufficient to cause self-sustained propagation of the first exothermic reaction. The polymeric material covers substantially all of the substrate and coating, and is different from the first and second materials. The polymeric layer, upon being thermally energized, reacts with at least one of the substrate and coating in a second exothermic reaction.Type: GrantFiled: September 8, 2010Date of Patent: December 17, 2013Assignee: Ensign-Bickford Aerospace & Defense CompanyInventors: Richard M. Kellett, David F. Irwin

Patent number: 8603271Abstract: Method and device for mixing and initiating a pyrotechnic charge, comprising at least one coherent porous fuel structure (16) and at least one oxidizer (8). According to the invention, the coherent porous fuel structure (16) and the oxidizer (8) are placed apart in a mixing device (1, 20) to prevent unintentional ignition, and in which the oxidizer (8), in response to the action of a force upon the mixing device (1, 20), for example upon firing of an artillery shell, is transported into the coherent porous fuel structure (16), after which the obtained pyrotechnic charge is initiated after a set time delay.Type: GrantFiled: November 8, 2012Date of Patent: December 10, 2013Assignee: BAE Systems Bofors ABInventors: Mats Runemard, Christian Vieider

Patent number: 8585840Abstract: A process for recovering the energetic component from plastic bonded explosives. The process uses high velocity kinetic energy in the form of gases, liquids, or solids, alone or in combination, to cause the structural failure of the adhesive bonding between the polymer matrix and energetic component for the purpose of providing adequate loci for the solvation of the energetic component by appropriate solvents.Type: GrantFiled: February 6, 2008Date of Patent: November 19, 2013Assignee: G.D.O., Inc.Inventors: Paul L. Miller, Steve J. Schmit
