  • Patent number: 5042441
    Abstract: A combustion system for internal combustion engines having a cylinder, at least one piston reciprocal in the cylinder and a combustion chamber with three regions for improving the combustion process, the piston having a piston head with an outer perimeter portion, a central recessed portion and a baffle with ports arranged over the recessed portion, the piston cooperating with a cylinder head or the head of an opposed piston to form an induction region that diminishes in volume as the piston approaches top dead center forcing gases in the combustion chamber through a central region defined primarily by the ports in the baffle to the dispersing region in the recessed portion of the piston, and a fuel injection system with an injector that delivers a staged series of fuel pulses in each cycle.

  • Patent number: 5039244
    Abstract: A toothbrush and toothpaste system utilizing a container for the toothpaste which includes a chamber having a movable piston within the same. A spline is generally centrally located within the chamber with the movable piston circumjacently located relative to the spline. The piston is intended to contact toothpaste which is loaded within the chamber. The pistons movement is biased in one direction along the line. A head is connected to the container and includes a bristle structure usable as a toothbrush. The head includes a passageway which communicates with the adjacent chamber of the container and the bristle structure of the head. A valve separated by movement of the spline opens the passageway permitting communication between the chamber and the bristle structure. Springs means is also included for closing the valve relative to the container. The piston continually moves along the spline during the delivery of toothpaste to the bristle structure in only one direction within the chamber of the container.

  • Patent number: 5013578
    Abstract: An apparatus and method for coating or layering a surface with a metal utilizing a metal vapor vacuum arc plasma source. The apparatus includes a trigger mechanism for actuating the metal vacuum vapor arc plasma source in a pulsed mode at a predetermined rate. The surface or substrate to be coated or layered is supported in position with the plasma source in a vacuum chamber. The surface is electrically biased for a selected period of time during the pulsed mode of operation of the plasma source. Both the pulsing of the metal vapor vacuum arc plasma source and the electrical biasing of the surface are synchronized for selected periods of time.

  • Patent number: 5003766
    Abstract: A gas turbine engine that can operate at a very high efficiency over a wide range of load conditions. In one important feature of the invention, combustion gases are discharged along two paths, one with constant energy and the other with energy that varies in accordance with the engine load. The constant energy discharge drives a turbine that, in turn, operates a compressor for the engine at a constant, high efficiency. Alternatively, the compressor is driven at a speed that varies inversely with the engine load such that the engine operates at a high efficiency for all loads. In another, independent feature of the invention, the combustion occurs at a stoichiometric ratio of fuel and air, with the turbine blades being protected from the vastly increased combustion gas temperatures by an internal array of passageways through which cooling liquid, e.g., liquid fuel, and air are channeled.

  • Patent number: 4974844
    Abstract: A ball structure utilizing a plurality of annular elements or disk-like members placed in side-by-side disposition with one another. Each of the members are constructed of soft, flexible, foam material. The side-by-side members are bound together at one place to cause compression of the foam material. The side-by-side members are bound at a second place along each of the annular members substantially opposite to the first binding place. Such dual binding causes compression of the soft flexible foam material forming the annular members into a ball.
