  • Patent number: 6016753
    Abstract: An explosive material-energized plasticized metal slug cutter for use within tubular cylinders, or pipe or similar structures-especially in buried or otherwise inaccessible locations is disclosed. The cutter includes explosive material initially disposed in a particular hourglass or dogbone shape and surrounded by a layer of explosive-plasticizable copper or similar material which becomes both heated to plasticity and imparted with kinetic energy upon explosive material detonation. The hourglass or dogbone shape of the explosive material provides focus or shaping of the copper metal into a confined slug pattern enabling a clean and relatively low expended-energy cutting of a surrounding tubular cylinder into axial segments. The cutter employs a cutting action inclusive of spalling at the outer surface of the cut tubing opposite the region of slug impact.

  • Patent number: 5910638
    Abstract: A castable explosive composition consisting essentially of about 50 to 90 weight percent tungsten powder, about 3 to 40 weight percent of a high energy explosive, about 3 to 16 weight percent of an energetic binder, and about 2 to 10 weight percent aluminum powder. The aluminum powder acts as a processing aid, virtually eliminating tungsten settling.

  • Patent number: 5698814
    Abstract: A penetrating bomb weapon comprising a long hollow cylinder constructed of high strength steel or similar material and including a pointed nose to aid in penetration of media such as concrete, soil, steel or a hardened surface. The cylinder contains an insensitive explosive that is separated into segments by shock attenuating materials so that one segment of the cylinder may detonate without detonating or destroying adjacent segments. The number of segments may be two or more depending on the complexity of the target to be attacked. Initiation of the main charge within each segment is achieved using explosive boosters positioned so that shocks transferred to adjacent segments, and the initiation train of these segments, is minimized. Separation of the segments is accomplished using explosive cutter charges which perforate and/or spall through the case wall of the penetrator bomb.
