Abstract: An arrow rest arrangement for an archery bow and a quick change launcher formed from a friction reducing noise arresting polymer composition in selected sizes and shapes to facilitate different types of arrows. The launcher supports the arrow prior to launching and provides initial guidance to the arrow at launch. The arrow rest includes a holder for retaining the arrow in position prior to shooting.

Abstract: An apparatus and method for stripping volatiles from a feed stream and concentrating the volatiles in the overhead vapors forming a condensate product and simultaneously producing a low percent volatiles outlet stream as a concentrate product. The volatiles separator and concentrator, ("VSC"), unit has many applications in the reduction and the concentration of volatiles in the beverage, fuel, and industrial alcohol industries, as well as in chemical applications for removing or stripping volatiles from heat sensitive feed substrates which require low temperatures and a short residence time to prevent degradation of the product. The preferred embodiment of the VSC unit utilizes a short feed stream preheat contact time in combination with turbulent high velocity flow at temperatures below 100.degree. F. to provide flash vaporization for volatiles separation with reboil capability to adjust volatiles concentration in the residue and product. The application of high vacuum in the range of 27" to 28.

Abstract: Method and apparatus for handling water used in plating processes to eliminate discharge of pollutants including a plating tank for chrome plating selected materials, at least one rinse tank which holds rinse water where parts from the plating tank are rinsed to remove chrome compounds used in the plating tank and transfer means to transfer water from the rinse tank to a purification tank where hydrazine is added to the rinse water in quantities sufficient to maintain selected pH in the water returned to one of the rinse tanks for precipitation of the chromic compounds to chromic hydroxide which can be easily filtered for disposal as a dry material. High quality water such as deionized water is added to the rinse tank to makeup lost water and a catalyst such as cobalt salt can be added to the purification tank to assist in reduction of the chromic compounds.

Abstract: A universal pump coupling system that allows various style submersible pumps to be mounted to a pump mounting frame assembly to be used interchangeably within a single pump station system. The universal pump coupling system comprises a submersible pump holding device and universal guide rail assembly for use in both submersible and converted dry pit pump stations that allow numerous brands of pumps to be utilized in a single interchangeable system. The universal pump coupling system is particularly suitable for conversion of wet well/dry well pump stations to a single wet well pump station.

Abstract: A lightweight, high strength disposable or recyclable corrugated pallet and corrugated collapsible container pack.
