Abstract: Mobile storage apparatus comprises a wheeled container for the storage of materials and a handle for facilitating the wheeling of the container across the ground or other supporting surface. The handle has extensible and retractable sections thereby enabling the handle, when in its extended condition, to provide hanging support for the contents of the container. The handle sections are hinged for rocking movements relative to one another to enable such handle sections to occupy any selected one of a number of angularly adjusted positions.

Abstract: An engine (10) and a method of operating it during cold start and ensuing running using a cold start aid such as a glow plug control (24) and glow plugs (22). The control (24) monitors all glow plugs to distinguish between one that is effective and one that is ineffective. When a glow plug is disclosed to be ineffective, the engine control system (14) reduces the quantity of fuel introduced into the respective combustion chamber (12) in comparison to the quantity of fuel that would be introduced were the respective glow plug effective. This is beneficial in keeping the collection of hydrocarbons of surfaces of a diesel particulate filter (20) from increasing due to an ineffective glow plug.

Abstract: An improved, large-format digital inkjet print engine that includes a group of co-operating print engine subassemblies that embody various novel elements that both discreetly and cumulatively advance the current art. The group of subassemblies and sensors cooperate to produce high quality graphic images using a plurality of different colors of ink and different types of print media at speeds several times faster than similar conventional inkjet printers. In addition, the use of cooperating elements permit the manufacture of complex, large-format digital color inkjet print engines that are less expensive to fabricated, operated, and serviced. The present invention finds use in large-format digital color printing and imaging, where successful repeatable printing requires precise placement of droplets of ink, toner or other marking material on a print medium such as paper, vinyl, film, or similar substrate.

Abstract: A motor vehicle, ATV and lawn tractor three-point hitch adapter that provides attachment of standard agricultural category one three-point hitch implements such as scraper blades, landscaping rakes or box blades. The adapter comprises of a tube that interfaces with the motor vehicle hitch receptacle, a bracket that interfaces with the category one implement's two pivot post attachment points, and a winch that interfaces with the category one implement's upper attachment point for raising and lowering the implement. The electric winch is connected to the vehicle battery and contains a switch for controlling up and down movement of the implement by the vehicle operator. The motor vehicle adapter can be also used with all-terrain vehicles and lawn tractors when a wheel assembly and hitch assembly are added. The wheel assembly comprises of a welded tube assembly that is bolted to the motor vehicle adapter, an axle, two wheels and cotter pins to hold the wheels in place.

Abstract: A liquid pump with a brushless motor constructed to be received within a liquid reservoir of a cooling system to deliver liquid coolant under pressure to a manifold assembly through which the coolant is discharged onto various electronic components to cool them. The pump has a pumping assembly, a rotor, a stator and an electronic control circuit which controls the operation of the pump and each of which is immersed in liquid coolant in the pump housing to cool them as the coolant flows through the pump. Further, because each component within the pump can be exposed to the liquid in the pump, no sealed enclosures are needed for the pump as a whole or for any component therein and the pump can be received directly in the reservoir.

Abstract: A fuel injector has a body containing a mechanism that is operable to cause fuel to be injected out of the body and into an engine combustion chamber. An electric actuator operates the mechanism to initiate fuel injection and to terminate fuel injection. The injector has an identity circuit that possesses an identity characteristic identifying a calibration category into which the fuel injector has been previously categorized based on data obtained from actual operation of the fuel injector. In some embodiments the identity circuit is electrically connected in shunt with the electric actuator and imposes no significant effect on the response of the fuel injector to the initiating and terminating electric signals. In others, it is connected between engine ground and one actuator terminal.

Abstract: A motor vehicle trailer hitch adapter that mates with a motor vehicle trailer hitch receptacle and provides attachment of standard agricultural category one three point hitch implements such as scraper blades, landscaping rakes or box blades. The adapter comprises of a tube that interfaces with the motor vehicle hitch receptacle, a bracket that interfaces with the category one implement's two pivot post attachment points, and a winch that interfaces with the category one implement's upper attachment point for raising and lowering the implement. The electric winch contains a wire harness that is routed into the vehicle for power attachment and vehicle operator control of the winch. The motor vehicle battery powers the winch through an interface such as a cigarette lighter socket.

Abstract: An adapter is mountable to a trigger mechanism of a conventional fire extinguisher to form a portable automatic fire extinguisher. The adapter comprises a compressed spring held in place with a heat release fusible link. If fire occurs in the vicinity of the adapter, the fusible link separates allowing the compression spring to depress the fire extinguisher trigger mechanism.

Abstract: A bridge failure alarm system designed to be used with bridges has a plurality of spans across the length of the bridge, activates an alarm whenever the distance between any two adjacent spans is greater than a predetermined safe distance. This is accomplished by providing a conduction path extending from one end of the bridge along a first side of the bridge to the other end of the bridge and then back to the first end of the bridge by a conduction path located on the other side of the bridge. Between every expansion joint located between each adjacent span of the bridge are two jumpers to provide electrical connection across the expansion joints, one jumper located on each side of the bridge proximate to each expansion joint. In this manner, should any one of the expansion joints exceed a predetermined width placing two adjacent spans at a distance greater than the predetermined safe distance, at least one of the jumpers located therebetween will break the conduction path causing the alarm to be activated.

Abstract: A throttle valve arrangement for an engine air intake includes an engine intake air passage having a longitudinal direction of air flow. A cylindrical bore extends laterally across the passage and has diametrically opposed openings longitudinally aligned with the passage. A cylindrical valve barrel or element is journalled for rotation within the bore and has an aperture extending diametrically therethrough for variably interconnecting the bore openings as a function of rotation of the valve element within the bore. A channel extends around the periphery of the valve element between opposite ends of the air aperture. A linkage projects from one end of the valve element for variably and controllably rotating the valve element within the bore between a fully open position in which the barrel aperture interconnects passages in the bore and a fully closed position in which air flow between the passages is routed through the channel around the periphery of the valve element.
