Abstract: An apparatus that regulates a flow of hydrogen and oxygen generated by fuel cells as supplemental fuel for an internal combustion engine, in which a microprocessor controller receives engine operating parameters, determines a fuel demand for the engine responsive to the operating parameters, and regulates the supply of power to the fuel cells for generating the supplemental fuel. A supply body holds process water supplied to the fuel cells. The generated hydrogen and oxygen communicate to an intake manifold of the engine. A method of regulating the disbursement of hydrogen and oxygen for supplemental fuel for an engine is disclosed.

Abstract: A system for managing moisture content of hydrogen and oxygen gas produced by a fuel cell for a fuel supplement for an internal combustion engine, with a tank holding process water and respective separate hydrogen and oxygen header spaces for receiving hydrogen and oxygen gas having moisture content wherein some moisture content forms droplets and falls into the process water yielding dried hydrogen and oxygen gases for communicating through supply lines to the engine as a fuel supplement during operation. A method is disclosed for managing moisture content of hydrogen and oxygen gas produced by a fuel cell for delivery as a fuel supplement to an engine.

Abstract: A wheeled collapsible stand for a power driven machine includes first and second frame units pivotally connected to each other and respectively pivotally connected to a tabletop bracing member that is adapted to support the machine thereon. The first frame unit includes front and rear frames pivotally coupled to each other such that the front frame is movable from an unfolded position to a folded position to displace the tabletop bracing member from a working position to a collapsed position. An extendible lifting unit is disposed to provide a lift to a front end of the tabletop bracing member to move toward the working position, and a buffer during movement of the tabletop bracing member to the collapsed position.

Abstract: A wheeled collapsible stand for a machine includes first and second frames pivotally connected to each other, a wheel unit mounted on a fulcrum region of the first frame, and a tabletop bracing member pivotally mounted on a pivoted end of the second frame and a weight end of the first frame for supporting the machine thereon. When the weight end is lifted by forcing a power end, the pivoted end is turned and lifted while a foot end of the second frame is lowered to rest on the ground so as to permit the tabletop bracing member to be displaced to a working position.

Abstract: A clamping apparatus for clamping a workpiece-blocking plate of a table saw includes a mounting member attached to a machine base, and a retaining plate mounted pivotally on the mounting member. The retaining plate has an L-shaped plate portion that supports the workpiece-blocking plate thereon and that is biased to press the workpiece-blocking plate against the mounting member. When the workpiece-blocking plate is removed from the apparatus, the retaining plate can be turned to a storage position, where the retaining plate is disposed within a notch in the mounting member and where the L-shaped plate portion is disposed within an L-shaped notch portion of the notch.

Abstract: A vacuum system (14) for a motor vehicle (16) comprising a litter box (18) mounted in any convenient location within an interior compartment (20) of the motor vehicle (16). A vacuum canister (22) is provided that holds trash in disposable vacuum bags to be disposed at a later date. A facility (24) is for electrically connecting the vacuum canister (22) to a battery (26) in the motor vehicle (16), to operate the vacuum canister (22). A component (28) is for fluidly coupling the vacuum canister (22) to the litter box (18), so that any litter deposited within the litter box (18) will be drawn through the fluidly coupling component (28) and deposited into the vacuum canister (22) to be disposed of at a later date.
