  • Combustion engine
    Patent number: 6386838
    Abstract: A reciprocating rotating engine having a combustion chamber and a pumping chamber is provided with two sets of free pistons and pumps vanes each set having two pistons and two pump vanes. The two sets of pistons and pump vanes define four separate combustion chamber portions and pumping chamber portions and reciprocally rotate in concentric circular paths under the force of compression ignited internal combustion forces, pumping and pressurizing hydraulic fluid contained within the pumping chamber.

  • Dual-mode inertia reel system
    Patent number: 4925124
    Abstract: An inertia responsive mechanism employs a freely mounted inertia mass in combination with a seat belt retractor mechanism wherein the inertia mass is sensitive to vehicle deceleration or to strap acceleration, or to both. Disclosed are a variety of arrangements for supporting an inertia mass in a manner to permit free movement of the mass including balls and recesses, conical post ends in holes, frusto-conical surfaces on tube ends and frusto-conical surfaces in combination with balls in grooves. Anti-lock mechanisms prevent inertial locking while the strap is retracting. In a compact inertia reel arrangement, a reel ratchet wheel directly supports the inertia mass. Also disclosed are mechanisms for manually resetting inertia reels.
