Abstract: The present invention provides a workpiece positioning device for precisely positioning a workpiece in a predetermined position relative to a power tool or other device quickly and efficiently. This device provides a simple and dependable apparatus for quickly and easily positioning a workpiece, and adjusting the position of the workpiece in small increments. The workpiece positioning device includes a fence member, having a surface thereon for abutting against a workpiece, the fence being disposed adjacent to a locator member for limited slideable movement right and left thereof, whereby a workpiece abutting the fence will be exactly located in the precise position selected.

Abstract: A method of conducting a racing competition among a plurality of racers comprising the steps of conducting qualifying races among the plurality of racers; awarding qualifying (Q) credits based on a predetermined formula and the results of each of the plurality of racers' qualifying races; arranging the racers in a reverse-qualifying order arrangement for the start of the race and assigning passing (P) credit values to the plurality of racers based on a predetermined formula and the racer's position in the reverse-qualifying starting order arrangement. The race is then started with the plurality of racers arranged in the reverse-qualifying order arrangement, the plurality of the racers are then awarded P credits during the course of the race based on a predetermined formula and the other racers each of the plurality of racers passes. At the finish of the race, the finish time and position of each of the plurality of racers is determined.

Abstract: A radon stripper system for removing radon from well water including a draft tube and an air supply line that is interfaced with a gas supply. The draft tube is vertically aligned beneath the surface of the water in a well. Gas is delivered into the draft tube a sufficient distance induces a flow in the well water. The gas interface between the gas delivered to the radon stripper system and the well water is increased. The induced water flow and increased gas to radon-contaminated water interface removes the radon from the well water.
