  • Patent number: 6354182
    Abstract: A launch assist system for supplementing the launch acceleration forces of a projectile, rocket or missile. An airtight chamber covered by a flexible elastic membrane supports a platform in the center of the membrane; the platform is electromagnetically coupled to a cocking mechanism that withdraws the platform into the chamber. Air within the chamber is removed and compressed to be stored in a holding tank as the platform is lowered into the chamber and as the flexible elastic membrane extends into the chamber. The electromagnetic coupling may be triggered to release the platform to permit the stored energy in the extended flexible elastic membrane, and in supplemental force members, to apply acceleration forces to a launch vehicle; the compressed air stored in the tank is simultaneously released to fill the chamber as the flexible elastic membrane is withdrawn.

  • Patent number: 6345460
    Abstract: A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.

  • Patent number: 6321630
    Abstract: A line charge for deploying explosive charges across obstacles and mines to clear a safe lane has explosive charges spaced apart on a common detonating cord, and axial passageways in the explosive charges are sized to permit free longitudinal travel of the detonating cord through them. A composite strength member includes an inner fabric sleeve of high strength flexible material covered by an outer sleeve of thermoset/thermoplastic material and contains the explosive charges and detonating cord. Heat-curing the inner fabric sleeve and outer sleeve shrinks and conforms them to the outer contours of the explosive charges and combines the high strength flexible material and thermoset/thermoplastic material. Composite strength member absorbs energy during deployment of the line charge over its entire length and circumference and absorbs more energy prior to structural failure to allow the use of more powerful rocket motors to fly longer line charges from much greater and safer standoff distances.
