Abstract: A computer input system includes a mouse including a housing having an interior surface defining an internal volume and a sensor assembly disposed in the internal volume. A processor is electrically coupled to the sensor assembly and a memory component having electronic instructions stored thereon that, when executed by the processor, causes the processor to determine an orientation of the mouse relative to a hand based on a touch input from the hand detected by the sensor assembly. The mouse can also have a circular array of touch sensors or lights that detect hand position and provide orientation information to the user.

Abstract: A supercharger system for an internal combustion engine in a vehicle driveline that includes a catalytic converter for oxidizing undesirable exhaust gas emissions including a single, dual-purpose air pump for establishing combustion airflow for the engine as well as for the catalytic converter including an automatic control valve system having an electronic microprocessor that monitors varying engine operating conditions for establishing optimum airflow for fuel combustion purposes and for oxidizing exhaust gas emissions throughout a range of operating conditions for the engine, the system including a variable ratio mechanical drive between the engine and the air pump.

Abstract: A locknut having a body portion with an outer surface and first and second ends, a thread extending inwardly into the body portion from the first end, a depression in the second end, an inwardly tapered lobed curvilinear surface defining the periphery of the depression for receiving a mating key, and an external thread extending from the second end onto the outer surface for receiving the internally threaded surface of a sleeve mounted on a key for attaching the key to the locknut. The locknut as described above including a rotatable sleeve mounted thereon with a shroud located radially outwardly of the external thread. A locknut as described above wherein the outer surface extending from the first end is frustoconical and terminates at an annular shoulder which is located radially outwardly of the external thread.

Abstract: A locking valve construction including a housing, a valve member in the housing, a fluid inlet and a fluid outlet in the housing, a valve member rotating key for rotating the valve member to an open position for selectively effecting communication between the fluid inlet and the fluid outlet, a holding member effectively mounted on the housing for holding the housing against rotation relative to a base when the valve member is being rotated by the valve member rotating key, and mounting structure for mounting the housing on the base for permitting the housing and the valve member to rotate as a unit in the event that the holding member is rendered inoperative to thereby prevent movement of the valve member relative to the housing to an open position.

Abstract: A diesel engine fuel supply system having an injector pump, a fuel tank, a fuel inlet conduit between the fuel tank and the injector pump and a fuel return conduit between the injector pump and the fuel tank, a venting fuel valve including a valve body, an adapter for mounting the valve body on the injector pump, a fuel inlet on the valve body for receiving the fuel inlet conduit, a fuel outlet on the valve body for transmitting fuel to the injector pump, a vent in the valve body in communication with the atmosphere, a valve spool in the valve body movable to a first position for effecting communication between the fuel inlet and the fuel outlet to supply fuel to the injector pump while preventing venting of the fuel outlet to the atmosphere through the venting means, and the valve spool being movable to a second position for preventing communication between the fuel inlet and the fuel outlet and for effecting communication between the injector pump and the atmosphere to thereby vent the injector pump and pre

Abstract: A locking valve construction including a housing, a valve member in the housing, a fluid inlet and a fluid outlet in the housing, a valve member rotating key for rotating the valve member to an open position for selectively effecting communication between the fluid inlet and the fluid outlet, a holding member effectively mounted on the housing for holding the housing against rotation relative to a base when the valve member is being rotated by the valve member rotating key, and mounting structure for mounting the housing on the base for permitting the housing and the valve member to rotate as a unit in the event that the holding member is rendered inoperative to thereby prevent movement of the valve member relative to the housing to an open position.

Abstract: A bolt type of lock structure including an elongated bolt member, first and second externally threaded ends on the bolt member, first and second nuts of frustoconical configuration threadably mounted on the first and second threaded ends, first and second faces on the nuts for receiving key members for tightening and loosening the nuts, an anaerobic thread locking compound on the threads, the bolt member being relatively soft throughout to withstand impact and having a hardened zone in a central area wherein it is exposed to chiseling or sawing. A nut of the type described above including a threaded bore in the face which receives a screw for securing the key member thereto. A stud having oppositely threaded ends and an irregular axial bore in one end for receiving a wrench and a hardened surface portion between the threaded ends.

Abstract: A frost detecting device for a refrigeration unit of the type having refrigeration coils and fins. The device is adapted to be mounted on the side of the unit with frost accumulating means projecting from the unit to contact at least one fin in a manner to accumulate frost thereon at about the same rate as the fin. The device carries means for detecting a predetermined amount of frost on the accumulating means, in order to activate a defrosting cycle.

Abstract: Paper or cardboard products are manufactured by mixing an aqueous solution or dispersion of a cationic starch with an aqueous suspension of a kaolinitic clay filler, and adding the resulting mixture to a stock of cellulosic fibres to form a furnish containing the kaolinitic clay filler, the cationic starch and the cellulosic fibres, which furnish is then formed into the desired paper or cardboard products, the amount of shear to which the mixture containing the clay filler and cationic starch is subjected being controlled to ensure that the furnish contains flocs of clay filler and cationic starch of a desired size.
