Abstract: A tubular pipe joint section has a) a first circular rim portion, b) a non-coaxial second circular rim portion, and c) an elliptical body wall extending from the first circular rim portion to the second circular rim portion.

Abstract: The present invention provides a feeding system suitable for mounting to a wheelchair and usable for individuals who have limited or no use of their hands. The system includes a housing that stores food product, and delivers the food product to a transfer mechanism. The transfer mechanism delivers the food product to a serving assembly that is positioned at a location proximal the user's mouth for consumption.

Abstract: A flow control structure is provided for the selective control of a liquid flow from an external body of liquid or for liquid and/or solid separation. The flow control structure includes a container, a float, and a valve. The container has an inlet, an outlet, and a closed bottom surface. The float is buoyantly positioned within the container and rises and falls in response to the level of liquid in the container. A valve is positioned inside the container and is coupled to the float by a linkage so that the valve opens when the float rises above a preselected height and the valve closes when the float falls to the preselected height within the container. The length of the linkage between the valve and the float determines the height of liquid required to open the valve. The valve may be positioned at an angle relative to the horizontal.

Abstract: A fuel injector includes an injector body and a three-way control valve having a valve element movable between first and second positions in the injector body. A check is disposed in the injector body and is movable to inject fuel when the control valve is in the second position and to block fuel injection when the control valve is in the first position. An actuator is selectively operable to move the valve element between the first and second positions. The injector includes a single clearance fit located in the control valve wherein the clearance fit is not exposed to a substantial pressure differential when the control valve is in the first position.
