Abstract: A system for controlling an automatic vehicle transmission, including a gear system and hydraulic clutches which hold a member of the gear system stationary to produce gear reduction or reverse, having an oil line which connects the clutches to an oil pressure source, a pressure control valve having a solenoid provided in the oil line which generates a regulated oil pressure to be supplied to the clutches in response to a current supplied to the solenoid, a switch valve provided in the oil line which switches the oil pressure to be supplied to the one of the clutches between the regulated oil pressure and a line pressure. In the system, it is discriminated whether the pressure control valve does not supply the regulated oil pressure to the clutches and if so, a dither current is supplied to the solenoid such that the valve repeatedly performs a vibrational motion to remove any grit therefrom, thereby removing grit without causing gear-shift shock or clutch vibration.

Abstract: Disclosed is a method of operating an internal combustion engine (20) with a fuel injection system (11; 12) including an injector (12) for delivery of a fuel-gas mixture to a combustion chamber (60) of the engine (20). The engine (20) includes a gas supply system (11; 13) pressurised at start-up through a pump-up sequence to a desired pressure for injection of fuel to the engine (20). In the pump-up sequence, the injector (12) is opened allowing pressurised gas to flow from the combustion chamber (60) through the injector (12) and into the gas supply system (11; 13). This pressurises the gas supply system (11; 13) when pressure in the combustion chamber (60) is higher than the pressure in the gas supply system (11; 13). Also disclosed is a method of operating an internal combustion engine comprising a plurality of banks of cylinders with a gas supply system for each bank of cylinders and a pressurised source of gas to supply pressurised gas to each said gas supply wherein, in the event of a failure to supply pressurised gas to each said gas supply system, one said gas supply system is employed in place of said pressurised source to provide at least some of the normal operating requirement of pressurised gas to said other gas supply system.

Abstract: A vacuum appliance is disclosed, comprising a collection canister and a powerhead housing a motor and impeller assembly for establishing vacuum pressure within said canister. In one embodiment, the appliance is of the wet/dry variety. A filter assembly comprising a rigid filter cage around which a filter is disposed. The filter cage is supported on an underside of the powerhead and extends into the collection canister such that the bottom of the filter assembly is at or substantially near the bottom of the collection canister. As a result, deflection of the collection canister as a result of vacuum pressure built up in the canister is resisted by the rigidity of the filter cage. In one embodiment, a frame within the powerhead serves the dual functions of supporting the motor and defining one wall or surface of an impeller chamber in which an impeller rotates to create the vacuum pressure. Barbed latches projecting from the powerhead function to removably secure the powerhead over the open top of the collection canister by engaging notches formed in the side of the canister. Substantially flat surfaces are formed in the vacuum's powerhead to facilitate the actuation of the latches, which is intuitively and ergonomically accomplished by a user resting his or her palm, thumb, or fingers on the substantially flat surfaces and grasping the latches with his or her free fingers.
