  • Fragment prevention screen for explodable fire suppressant panels
    Patent number: 4132271
    Abstract: A military vehicle equipped with a hollow panel containing a fire supprest, the panel being located directly inboard from one of the vehicle fuel tanks, whereby enemy projectiles fired into the tank also penetrate the panel; fire suppressant sprays out of the hole formed by the projectile, thereby preventing formation of or extinguishing a potential fireball within the vehicle before it can grow into a massive holocaust of lethal proportions. A foraminous screen is positioned on the inboard face of the panel to prevent the panel from fragmenting as the suppressant enlarges the hole formed by the projectile.

  • Engine mount
    Patent number: 4131256
    Abstract: An engine mount wherein the engine carries two oppositely-moving jaws adad to clamp against opposite side surfaces of a hold-down element carried by the vehicle. The jaws are actuated for opening or closing movements by means of a single screw extending through both jaws. The screw threads engaged with one jaw are right-handed, and the screw threads engaged with the other jaw are left-handed, for producing the desired jaw motions. The jaws and actuator screw are freely adjustable as a unit whereby the jaws apply equal pressures on the hold-down element.

  • Radiator shutter for arctic vehicles
    Patent number: 4124066
    Abstract: A shutter mechanism for an engine radiator comprising a series of rigid pus tubes having elastomeric sleeves secured thereto. Introduction of pressurized fluid (e.g. compress air or engine coolant) into the porous tubes pressurizes the spaces between the tubes and sleeves, thereby causing the sleeves to balloon outwardly to fully or partly close the air supply passage leading to the radiator. Depressurization of the tube interior spaces allows the elastomeric sleeves to contract onto the tubes, thereby opening the radiator air passage system.

    Patent number: 4121666
    Abstract: In a military vehicle having an upright fuel tank, an improved hollow panel ontaining pressurized fire-suppressant, the panel being located so that the suppressant sprays through an opening formed in the panel by an enemy projectile after its passage through the fuel tank. The hollow panel is reinforced against premature bursting forces by the provision of internal partitions running parallel to the major axis of the panel; the major walls of the panel are curved or bowed parallel to the minor axis of the panel to further reinforce the panel against premature bursting.

  • Self load/unload transporter
    Patent number: 4120413
    Abstract: A trailer for transporting containerized freight, said trailer including ced horizontal rails that can be mechanically spread apart to define a circumscribed space wider than a standard freight container. The trailer can be driven in a reverse direction so that the rails move alongside the freight container. Lift devices on the trailer hoist the container upwardly above the plane of the rails, after which the rails are mechanically shifted toward one another to underlie the container. The container is then lowered onto the rails for transport to another geographical location.

  • Hydraulic control for hydromechanical transmission
    Patent number: 4111074
    Abstract: A power transmission that includes hydraulically-operated clutches that are electively supplied with operating fluids by a selector valve that is controlled by an error signal means constructed to compare prime mover speed and user demand speed. The transmission preferably is a split torque hydromechanical transmission having one power path going through a hydrostatic pump-motor unit and another path going only through epicycloidal gearing system containing the hydraulically-operated clutches. The transmission is controlled hydraulically rather than mechanically, thereby avoiding problems relating to mechanical slack, response lag, and reliability.

  • Non-recurrent pulse generator
    Patent number: 4110812
    Abstract: A load power supply is connected to the load device through a gated switch nd time-delay fuse. The maximum current pulse delivered by the power supply is limited by the "delayed blow" characteristics of the fuse inserted in the circuit. After a selected current-time duration is delivered to the load, the fuse "blows" (opens) and the circuit is effectively de-energized.
