  • Patent number: 5490748
    Abstract: A stanchion for supporting a semi-trailer for transport on a bed of a rail car comprises a generally vertically-oriented support member having a base end and a top end, with a fifth wheel mounted to the top end. A diagonal strut attached to the support member extends angularly downward. A first plate member is positioned on the rail car bed and has a first pin extending therethrough and into the rail car bed for pivotally attaching the plate member to the rail car. A second pin extends through the plate member and into the rail car bed to prevent rotation of the plate member about the first pin. Flanges on a top surface of the plate member are attached to the support member and the strut, allowing orientation of the fifth wheel to be reversed by rotating the plate member about the first pin.

  • Patent number: 5458292
    Abstract: A fuel injection nozzle has an outer body member and an inner body member, the inner body member being slidingly positioned in a secondary axially extending cavity in the outer body member and including a valve needle slidingly positioned in a primary axially extending cavity in the inner body member. The inner body member acts as a first fluid pressure actuated valve needle for injecting fluid between the inner member and the outer member when the inner member is displaced axially by fluid pressure. The valve needle acts as a second fluid pressure actuated valve member for injecting fluid through an extension of the second axially extending cavity when the valve needle is displaced axially by other fluid pressure. First fluid orifices extend through an end of the outer member for spraying fuel released by displacement of the inner body member. Second fluid orifices extend through an end of the inner member for spraying fuel released by displacement of the valve needle.

  • Patent number: 5271357
    Abstract: Apparatus and a method of introducing a primary fuel, which may be a coal water slutty, and a high combustion auxiliary fuel, which may be a conventional diesel oil, into an internal combustion diesel engine comprises detecting the load conditions of the engine, determining the amount of time prior to the top dead center position of the piston to inject the main fuel into the combustion chamber, and determining the relationship of the timing of the injection of the auxiliary fuel into the combustion chamber to achieve a predetermined specific fuel consumption, a predetermined combustion efficiency, and a predetermined peak cylinder firing pressure.
