Abstract: A bearing for use with a snowmobile track is disclosed. The bearing includes an axle surrounded by a sleeve which is free to rotate when the snowmobile track is driven by the machine. The rails of the suspension systems of the snowmobile ride on the rolling surface resulting in reduced friction. The bearing can be used in a clip on the track or can be included in the track itself. A lubricious coating is utilized to reduce friction between the axle and the sleeve or bushing rotating about the axle.

Abstract: Heat transfer fluid compositions comprising (a) a terpene component, comprising at least one terpene; and (b) an alkylbenzene component, comprising at least one alkylbenzene; wherein the components are provided in an effective amount such that the 5resultant composition retains the liquid phase at temperatures in the range from about 0.degree. F. to below about -120.degree. F., preferably from about 0.degree. F. to about -175.degree. F.

Abstract: A precision high-pressure control assembly for supercritical fluids comprises a continuous flow system having a pressure control loop which includes a source of fluid communicating with a piston driven pump. A pressure sensor monitors the pressure of the supercritical fluid in the outlet line of the pump. A pressure controller has an input for receiving a signal relating to the pressure sent by the pressure sensor and the pressure controller yields an electronic output signal to an electropneumatic regulator. A source of air communicates with the electropneumatic regulator to provide pressurized regulated driver air directed to the pump. The electropneumatic regulator controls the regulated driver air pressure of the pump in accordance with the signal received from the pressure controller. The piston head of the pump is in a cryogenic chamber to minimize flash and cavitation.

Abstract: A process of and device for separating fluids of different densities involving transporting the fluid mass from a turbulent flow region and into a laminar flow region and then into a further separation area having a geometry sufficient to provide for the natural separation of fluids due to fluid density and then forcing the separated fluids from the chamber by system backpressure.

Abstract: A fuel injection system that includes an injector having a pintle movable within a housing for selectively opening and closing communication between inlet and outlet ports in the housing. The inlet port is connected to a source of fuel under pressure, while the outlet port is connected to a nozzle for delivering fuel under pressure to the engine. A section of magnetic material is coupled to the pintle, and a permanent magnet is mounted on the engine flywheel, such that magnetic forces imparted as the permanent magnet moves therepast moves the pintle against a spring to open communication between the inlet and outlet ports, and thereby deliver fuel under pressure from the source to the nozzle. A cam mechanism is rotatably positioned within the pintle housing and operatively coupled to the pintle for adjustably varying stroke of the pintle within the housing, and thereby varying time duration during which the injector opens communication between the fuel source and the nozzle.
