Abstract: An apparatus and method for enhancing dissolution of gases in liquids by ejecting the gas-liquid mixture through nozzles in a reaction vessel. The nozzles are pressurized, sized and directed to produce micro-fine gas bubbles in the liquid and to initiate rotational flow of the gas-liquid mixture in the reaction vessel. The small bubble size and rotational flow maximizes the time the gas is in contact with the liquid. The apparatus and method are used to increase the dissolution of ozone gas into aqueous solutions to increase the decomposition of aqueous-based organic compounds, precipitation of heavy metals, and destruct and/or deactivate enteric viruses, enteric bacteria, and protozoans. An alternative embodiment mixes the gas with the liquid prior to ejection through the nozzles.

Abstract: The present invention describes a workholding apparatus for holding workpieces that are to undergo various machining processes. The workholder apparatus is particularly suitable for numerically controlled machining applications. The workholder consists of a main body having a generally flat work surface and two or more clamping assemblies slidably located beneath the work surface. The invention includes a means for accurately and repeatably clamping a workpiece to the work surface, so that a part may be removed at an intermediate stage for examination or other processing, and returned to the workholder in the same location. A major advantage of the present invention is the clamping is accomplished without producing undesirable stresses in the workpiece, and all sides of the workpiece can be exposed for machining without changing the attachment of the workpiece in the workholder. A modular and extensible embodiment of the invention is also described.

Abstract: A stack of plastic T-shirt type bags for use with a dispenser. Each bag in the stack has a pair of handles with aligned apertures for receiving the prongs of the dispenser. The stacks are retained in alignment by a releasable flap on the periphery of the aperture in each aperture integral with the bag. The stack provides for the releasable securement of adjacent flaps together for retention of bags in overlying aligned relation in the stack. Each bag has at least one discrete region of weakness between each aperture and the inward side of the respective handle stack which can be broken for detachment of a bag from the dispenser. The stack is adapted to dispensers with prongs carrying surface projections (i.e. transverse ridges) to restrict unwanted sliding of the stack along the prongs.
