Abstract: A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The sleeve receives a gasket that forms a seal between the sleeve and the housing, the gasket having an opening surrounding a side hole of the sleeve to permit fluid to pass through the side hole between a pump volume and an inlet port or outlet port of the housing.

Abstract: A method for removing contaminants from industrial exhaust gas. The method includes contacting the exhaust gas with a mist of water and RNH2 (amine) to form a liquid solution of CO2. The method further includes extracting the liquid solution of CO2 and contacting the exhaust gas with granular activated carbon.

Abstract: Portable objects such as luggage, cases, purses, bags, sporting equipment, weaponry and the like typically have a handle and a detachable shoulder strap. The discomfort caused by the weight of the object and the shock to both carrier and object of walking is alleviated by clipping an elastic apparatus between the ends of the shoulder strap and the portable object. Disclosed is a short elastic suspender that includes an elastic strap to be removably attached by a first connector to the D-ring of a portable object. The other end of the suspender has a D-ring connector configured to removably be attached to by the snap/hook fastener of the original shoulder-carrying strap of the portable object.

Abstract: A tennis racket includes a frame with a head and a shank portion. The shank portion has an outer periphery with top, bottom, side and diagonal outside surfaces arranged generally in an octagonal configuration. A preformed handle includes a core with a hollow interior having upper, lower, lateral and angled surfaces therein arranged to define generally an octagonal configuration. The surfaces in the interior of the core are sized to conform to the outside surfaces of the shank portion of the frame, and may include longitudinally extending flutes to reduce vibration, weight, and shock in the handle.Handles of different grip sizes are preformed separate from the frames. The core elements are one piece, and may therefore be wrapped with leather or other gripping material and stored separate from the frames. When a finished racket frame is desired, adhesive is applied to the shank portion of the frame, and the handle slides over the end of the frame and seats on the outside surfaces.
