Abstract: A jump starter unit for starting large vehicles and other equipment using jumper cable at lengths up to fifty (50) feet. The jump starter includes a high output (200-300 amp) alternator and a large (2000 Farad) capacitor. The alternator is also used to maintain the capacitor's charge when the boost charge is not needed. The alternator and capacitor are integrated into an electrical system that includes an electronic control and a plurality of relays that provide the various charging and boost functions of the unit. In certain embodiments, the jump starter unit may take the form of a portable or mobile self contained apparatus having its own combustion to drive the high output alternator. In other embodiments, the jump starter unit may be integrated into a service vehicle, such as a tow truck or utility vehicle, and utilize the vehicle's engine to drive the jump starter's high output alternator.

Abstract: Methods and separator suitable for separating a gas from a liquid within a gas-liquid mixture. The separator includes a tank having a sidewall and oppositely-disposed endwalls that enclose an interior of the tank. An inlet to the tank directs a gas-liquid mixture against the sidewall of the tank within a first primary separation section to impart a circumferential flow direction to the mixture along the sidewall and initiate separation of a gas and liquid from the mixture. A reservoir located in a lower region of the tank collects the liquid separated from the mixture. A passage within a second primary separation section receives the gas separated from the gas-liquid mixture through an entrance thereof located in an upper region of the tank, and the passage directs flow of the gas into a secondary separation section, from which the gas exits the tank through an outlet.

Abstract: A pressurized fluid delivery system and method that can be used to interrogate objects, such as the interrogation and detonation of IEDs. The system and method entail pressurizing a liquid within a vessel with a compressed gas source so that the liquid within the vessel is at a pressure above atmospheric pressure. The pressurized liquid, the compressed gas, or a mixture thereof is then selectively delivered to an outlet, and then discharged from the outlet to physically interrogate the object.

Abstract: A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.

Abstract: An improvement in vehicle power take-off equipment is disclosed wherein a generator is affixed to the rear of the housing of a rotary air compressor of the type that is driven from a vehicle power take-off to an input shaft at its front end. The generator's housing is attached to the rear end of the air compressor's housing and the generator includes an armature mounted for rotation in the generator's housing. A rotary shaft extension projects from the rear of the air compressor. The armature receives the extension shaft and is coupled thereto by a friction fit and a threaded stud therebetween so that the armature turns with the extension shaft. The extension shaft is coupled for operation by the input shaft of the compressor so that both compressor and generator are directly operated by the input shaft of the compressor.
