| 20120061520 | LOW SHOCK FRANGIBLE JOINT - A frangible joint structure includes shock attenuation features formed as an integral part of the joint structure. Shock attenuation is achieved through use of, for example, slots or grooves that are machined directly, or otherwise formed integrally, into the frangible joint structure. Adequate shock attenuation is achieved solely by the features machined or otherwise formed in the frangible joint together with the typical assembly of the frangible joint into various structures (e.g., as a payload separator for rockets, missiles, satellites, etc.), without the need for additional hardware components and thus without the need for assembly of the frangible joint shock attenuation device. | 03-15-2012 |
| 20120055594 | SLOW BURNING HEAT GENERATING STRUCTURE - 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. The second exothermic reaction yields a second amount of exothermic energy that, when combined with the first amount of exothermic energy, is sufficient to propagate the first exothermic reaction in a self-sustained manner. | 03-08-2012 |
| 20100258914 | SURFACE MOUNTABLE SEMICONDUCTOR BRIDGE DIE - A semiconductor bridge die may have an “H-design” or “trapezoidal” configuration in which a center bridge segment is flanked by one or more angled walls on each side of the bridge segment. Each wall is plated with a conductive material, thereby providing a continuous conductive path across the top surface of the die. A bottom surface of the die may be connected to a top surface of a header by epoxy in various configurations. The plated angled walls facilitate the solderable connection of the walls to a plated top surface of each of several pins on a top surface of the header, thereby providing a continuous electrical connection between the pins and the die. Also, a method is provided for manufacturing a semiconductor bridge die in accordance with the various embodiments of the die. | 10-14-2010 |
| 20100043661 | EXPLOSIVE CUTTING CHARGE - An explosive cutting charge is formed by machining or otherwise forming a cavity of a desired configuration within a circular ring of metal cutting material such as copper or aluminum. The cavity may then be filled with an explosive material. The cutting characteristics of the cutting charge may be controlled by the selected cross-section configuration of the cavity. The ring may contain a booster explosive charge with connections to the active portion of the ring having the cutting metal material. | 02-25-2010 |
| 20090090440 | EXOTHERMIC ALLOYING BIMETALLIC PARTICLES - The compositions of different energetic metallic particles and corresponding coatings are chosen to take advantage of the resulting exothermic alloying reactions when the metals are combined or alloyed through heat activation. Bimetallic particles composed of a core/shell structure of differing metals are chosen such that, upon achieving the melt point for at least one of the metals, a relatively substantial amount of exothermic heat of alloying is liberated. In an embodiment, the core metal is aluminum and the shell metal is nickel. The nickel may be applied to the outer surface of the aluminum particles using an electroless process from a metal salt solution with a reducing agent in an aqueous solution or a solvent media. The aluminum particles may be pretreated with zinc to remove any aluminum oxide. The resulting bimetallic particles may be utilized as an enhanced blast additive by being dispersed within an explosive material. | 04-09-2009 |
| 20090078345 | HEAT GENERATING STRUCTURES - A heat generating structure includes a substrate of a first material and a second material coating at least a portion and preferably all of the first material, where the second material is different from the first material. The structure also includes an additional material or compound such as ammonia borane that is impregnated or located within the structure. When the structure is thermally energized, the first and second materials react with each other in an exothermic and self-sustaining reaction that pyrolyzes the impregnated ammonia borane compound to create a target gas, for example, hydrogen from the ammonia borane. An additional material, for example, a thermite, may be interposed between the structure and the ammonia borane to facilitate the ignition of the ammonia borane. | 03-26-2009 |
| 20090031911 | SLOW BURNING, GASLESS HEATING ELEMENTS - A structure includes a substrate of a first material and a second material coating at least a portion of the substrate, where the second material is different from the first material, where the first and second materials, upon being thermally energized, react with each other in an exothermic and self-sustaining alloying reaction that propagates from a first location within the structure along a travel path to a second location within the structure at a rate that depends upon one or more characteristics of the first and second materials. | 02-05-2009 |
