Abstract: An elongated particulate trap to fit the area usually occupied by the vertical cylindrical muffler, as on a large diesel truck, consists of rings of axial flow filter elements and a disc-like axial flow end filter element stacked in a trap housing, having an exhaust inlet and outlet at opposite ends, so as to provide a central flow passage for entry of exhaust gases via the exhaust inlet and so as to define with the trap housing and exhaust passage in flow communication with the exhaust outlet. The filter elements are stacked in spaced apart relationship to each other whereby to provide an axial gap therebetween to allow radial flow on one face of the filter elements. The axial gaps are sealed alternately on inner and outer radial ends to define outlet and inlet passages, respectively and to force axial flow through the filter elements whereby particulates will be removed from the exhaust gases.

Abstract: An offshore service vehicle of tricycle configuration employs three vertical legs to support a platform which remains above the water surface as the vehicle travels from a dry land station outwardly to service stations offshore such, for example, as a stationary tower or anchored barge. One of the legs at a forward location is rotatable for steering. Wheels at the bottoms of the legs are individually driven by motors in sealed housings immediately adjacent of the legs.

Abstract: A compression operated diesel fuel injector, for use with an internal combustion engine, is provided with a compression operated piston that is associated with a pump cylinder and plunger to effect pressurization of fuel for discharge from the injector, the piston also defining with the associate injector housing a fuel control chamber. A solenoid actuated valve is operatively positioned to normally block the return flow of fuel from the fuel control chamber to the fuel reservoir for the engine and, a variable flow orifice means is operatively positioned downstream of this valve to control the return fuel flow pressure as a function of engine speed and load to thus regulate the return flow of fuel from the control chamber so as to thereby control engine compression operation of the piston and, accordingly, to correspondingly regulate the rate of fuel injection from the fuel injector.

Abstract: A compression operated injector for delivering fuel directly to the combustion chamber of an engine has a piston which responds to the pressure in the combustion chamber and cooperates with a stepped plunger in the injector to pressurize fuel in both a control chamber and in an injector pump chamber. The discharge of fuel from the injection pump chamber for injection into the combustion chamber is controlled by a pressure operated valve. A solenoid actuated valve is used to control the escape of fuel from the control chamber so as to permit the piston to effect the necessary pressurization of the fuel in the injection pump chamber whereby to initiate the start of fuel injection.

Abstract: A strip of metal under tension is driven over an anvil wheel where the strip is contoured by a milling cutter. The moving strip is punched to provide an indexing hole. The milling cutter is programed to advance toward or to retract from the anvil wheel based upon the linear travel of the metal strip, and the punch is activated based upon the linear travel of the strip.

Abstract: In a compression operated injector, a solenoid valve is used to control the flow of pressurized fuel from a compression operated pump to the discharge nozzle of the injector so that the start and end of injection can be controlled by operation of the solenoid valve.
