  • Patent number: 8608878
    Abstract: 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.

  • Patent number: 8603271
    Abstract: 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.

  • Patent number: 8568543
    Abstract: An explosive composition is provided that is comprised of a Heavy ANFO and grain hulls. In one embodiment, the grain hulls are comprised of rice hulls. The grain hulls serve both as an inert bulking additive that reduces the density of the composition and as a sensitizer that reduces the energy needed to reliably detonate the composition. Also provided is a method for manufacturing an explosive composition comprised of Heavy ANFO and grain hulls, such as rice hulls. Additionally, a method of using an explosive comprised of ANFO and grain hulls in a mining operation is disclosed.
