  • Patent number: 8650756
    Abstract: Methods and systems to manufacture bonded corrugation truss-based structures. This allows the ability to change the dimensions of the individual structural features of the corrugations, i.e. thickness of the core, face sheet thickness, relative density of the core, and the alloys. The nodal design which provides ideal stress/strain distribution for in-plane and out-off plane loading. The node has a curved/smooth triple point intersection which in turn can provide best load transfer interface with high integrity/toughness. The bonded corrugation truss based structure can be continuous to any length only limited by the volume of the extrusion billet and the press capacity. An aspect of the bonded corrugation structures may include friction stir welding of the face sheets or any fusion welding of panels with edge members for strengthening allows fabrication of panels of any width and length. Bonding panels enables the fabrication of structures of any width.

  • Patent number: 4414610
    Abstract: A laser-sighted firing device adapted to be carried in a portable enclosure, such as a briefcase, to conceal the device from detection. The device includes a firing piece and a laser-type sighting device mounted on a rigid base. The sighting device is adapted to project an aiming spot to a target along a sight line generally parallel to the line of fire of the firing piece. The sighting device is resiliently mounted on the base and means are provided for adjusting the device to calibrate the laser spot relative to the line of fire of the firing piece. The firing piece has a trigger mechanism that is operated by a lever pivotally mounted at one end on the base and connected at the other end to a solenoid-actuated operating means. The lever is operatively connected intermediate its ends to the trigger mechanism for firing the piece in response to actuation of the solenoid.
