  • Patent number: 6560942
    Abstract: An open-lattice, foldable, self-deployable structure with a number of spaced, bendable longitudinal members each having a curved cross section forming cells each bounded by a portion of two spaced longitudinal members and two spaced diagonal members. The diagonal members are joined to the longitudinal members at the cell boundary intersections of the diagonal members and the longitudinal members. The longitudinal members are made of a material which bends and flattens by a predetermined amount below the material's yield point and the diagonal members are made of a material which both bends and twists by a predetermined amount below the material's yield point so that the structure can be collapsed and then self resurrected.

  • Patent number: 6546837
    Abstract: A method of manufacturing a dual load charge in a single consolidation pressing operation. A first type explosive is placed in a cavity to form a booster charge. A pocket is formed in the booster charge. A second type explosive is disposed in the pocket of the booster charge to form an initiating charge therein. Finally, the booster charge and the initiating charge are preferably simultaneously consolidated to form a dual load charge with intimate contact between the booster charge and the initiating charge. Also disclosed is a press useful for implementing the method of the invention.
