Abstract: A non-obtrusive activity monitor is proposed for advantageously monitoring and tracing disjunct, concurrent computer system operations in heavily queued computer systems. For each traced and pending computer system operation, the monitor uses a hardware implementation of an event triggered operation graph to trace the path of the computer system operation through the computer system. For each followed path, a unique signature is generated that significantly reduces the amount of trace data to be stored. In a preferred embodiment, the trace information is stored together with a time stamp for debugging and measuring queuing effects and timing behavior in a computer system.

Abstract: An integrated fuel delivery module for a fuel injected engine includes a fuel rail having a fuel distribution channel and a plurality of spaced-apart fuel injector sockets connected with the fuel distribution channel. A high-pressure fuel pump has a high-pressure chamber connected internally to the fuel distribution channel without external high-pressure fuel lines.

Abstract: A protective packaging unit for a bottle or jar is described. Said unit comprises a molded plastic sheath which is closed at the top, open at the bottom, possesses a means for releasably holding the bottle or jar, and has cutaway sections in opposite sides that enable the bottle or jar to be grasped between finger and thumb and pulled from the sheath. The packaged consumer product comprising the bottle or jar and the sheath is easy to assemble and to use.

Abstract: A fuel delivery module integrates a fuel rail, with its associated connections, features and components, with the injectors for one bank of a direct injection engine. When the module is secured to the engine, loading springs between the inlet ends of the injectors and abutments in the mounting recesses accommodate variations in manufacturing and assembly tolerances to provide adequate but not excessive loading of the injectors against associated seats of the engine. Manufacturing and assembly costs are reduced by the use a module with injectors pre-installed. Also, the module may be pretested in a suitable test fixture prior to installation to assure proper flow and spray development from each of the injectors. The module may integrate other components also, such as intake air passages, EGR passages and coolant passages and their associated components. Various examples of injector loading springs are described.

Abstract: An intake manifold assembly includes an improved air intake manifold receiving novel side feed fuel injectors. A fuel rail is integrated as a common part defining a common fuel passage integral with the air intake manifold. The common fuel passage supplies the side feed fuel injectors through openings that are spaced away from the injector nozzles toward an opposite connector end of each injector. The injector design concentrates an actuating coil, armature and nozzle valve in a lower or nozzle end of the injector. The fuel is fed from the side feed opening through an axially centered fuel passage that extends through the coil and the associated armature to the injection valve in a manner identical to corresponding top feed injectors. Thus, the performance advantages of top feed injection systems are provided while gaining the reduction in cost attributable to elimination of the separate fuel rail and subassembly. Various arrangements are disclosed for retaining the injectors in the manifold assembly.

Abstract: Disclosed is a lubricating composition having a major amount of an oil of lubrication viscosity and a minor amount of (A) a nitrogen containing dispersant with a total base number of from 20 to 160 on an oil-free basis wherein the improvement comprises adding to said dispersant; (B) a sludge preventing/seal protecting additive of at least one aldehyde or epoxide or mixtures thereof.

Abstract: A fuel rail has a high pressure inlet and a low pressure outlet. The high pressure inlet feeds pressurized fuel to a plurality of injectors along the fuel rail. A fuel return line, which is connected with the low pressure outlet, is positioned substantially centrally of and coaxial with the fuel rail. The fuel return line is non-circular in configuration having a width to height ratio greater than one. The configuration of the return fuel line and the flexibility of the walls thereof provide a damper that reduces the pressure pulsations in the high pressure fuel.

Abstract: Disclosed is a lubricating composition having a major amount of an oil of lubrication viscosity and a minor amount of(A) at least one thiocarbamate wherein the improvement comprises adding to said thiocarbamate(B) a sludge preventing and seal protecting amount of at least one aldehyde or epoxide or mixtures thereof.
