  • Patent number: 5839927
    Abstract: The invention provides a water jet system with higher efficiency and better steering. The water jet system uses cantilever bars for an inlet grating, to prevent blockage. The water jet system also uses an elliptical impeller shaft housing to reduce turbulence and snagging of debris by the rotating impeller shaft. The water jet system uses impeller blades with a curved cross section that curves towards the direction of forward rotation. The water jet system uses U-shaped flanges mounted to the outlet of the water jet to provide steering.

  • Patent number: 5819068
    Abstract: A simulation engine for temporally driven functional causal model application program is disclosed. An object oriented approach is used to create model definitions in which a system of interacting agents are assembled into a tree structure of agents and subsystems. The interacting agents which exhibit or endowed with time dependent behaviors are identified and are given priority in a queue. The temporal nature of the interacting agents and other characteristics are considered in the simulation of the model.

  • Patent number: 5773747
    Abstract: This invention relates to a material handling system. More particularly, the invention pertains to the method and apparatus for automatically loading a two-piece ammunition into a gun tube. A continuous rammer mechanism having a plurality of strategically spaced pawls is structured to accelerate the two-piece ammunition into the gun tube. The system compensates for different angles of gun trajectory by adjusting the speed and output of a drive motor to thereby provide a consistent ramming acceleration of the ammunition.

  • Patent number: 5752862
    Abstract: A center mounted power train configuration for a high water speed tracked amphibious vehicle which mounts the engine above the waterjet inlet plenum to shorten the power train length, so as to allow the vehicle length and weight to be optimized for land and water mobility. The short power train length provides for use of alternate longer components which may be required to obtain adequate power and thrust. Center mounting the power train reduces air ingestion into the waterjets and maximizes the sharing of support structure to lighten the vehicle. Center mounting of the power train also optimizes efficiency by using one propulsion gearbox to transfer power and improves access to components for repair or replacement. The power train arrangement features a rearward center of gravity for enhanced land and water mobility and provides space for locating personnel, for mission equipment and for access to floor level suspension components.

  • Patent number: 5723807
    Abstract: A method, apparatus and article of manufacture is disclosed for using stand-up expanded metal armor members for protecting vehicles or other objects from ballistic threats. One or more spaced expanded metal member has projectile engaging faces which present sharp edges and arcuate surfaces to the small point of the projectile. When the point of the projectile engages the faces of the expanded metal members, the projectile is progressively deflected or shattered causing the wide arcuate side surface of the projectile to stop the projectile, or to pass through some or all of the members and engage the protected object with less than lethal force.

  • Patent number: 5705218
    Abstract: The invention provides a rotary processor, which uses magnetic fields to increase the heating or cooling of containers. The invention provides the magnetic fields along the sides of the rotary processor before or after the containers are rotated under the force of friction due to gravity. The magnetic field increase the number of transition phases of rotation, by creating a force of friction caused by the magnets which will rotate the containers and then removing the magnetic fields so that the containers stop rotating.
