Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

Abstract: A fuel supply device includes a main body, fuel chamber, fuel supply pipe and a fuel valve. The main body has a main bore with an inlet for air and an outlet through which a fuel and air mixture flows. The fuel chamber retains a supply of fuel. The fuel supply pipe has a passage communicating with the main bore and through which fuel from the fuel chamber flows to the main bore. And the fuel valve has a valve seat, a valve element movable relative to the valve seat between an open position and a closed position, an inlet upstream of the valve seat and is in communication with the fuel chamber, and an outlet downstream of the valve seat. The outlet is coaxially aligned with the passage of the fuel supply pipe and the fuel valve is electrically operated to move the valve element.

Abstract: The present invention is drawn to methods for sampling and/or testing for the presence of whisker-like metallic particulates in data centers or computer rooms. For example, a method for discovering the presence of an undesired whisker-like metallic particulate in a data center is disclosed comprising providing a tool having a conductive adhesive portion wherein the conductive adhesive portion is capable of capturing and retaining the whisker-like metallic particulates in their fragile condition, locating a surface of the data center where metallic particulates may be present, extracting from the surface any whisker-like metallic particulates present in substantially their fragile condition using the tool, and confirming with an electron microscope whether or not any whisker-like metallic particulates are present on the conductive adhesive portion of the tool.
