Abstract: A fuel saver and contaminant reduction device, comprising: a cylindrical housing with a tubular fuel conduit through which the fuel flows, the pipe with a fuel inlet in fluid communication with the fuel tank of a vehicle, and a fuel outlet in fluid communication with the fuel line feeding into a vehicle's engine. The cylindrical body including at least two sets of aligned transversal orifices in each of which a permanent magnet is inserted where each magnet includes distinct north and south poles. Each pair of permanent magnets is arranged such that a north pole of each magnet faces the other, and the axis of magnetization is perpendicular to the flow of fuel. The cylindrical housing is covered by an external rigid case.

Abstract: A beat finder is provided for accurately and repeatably setting a speed control on a turntable, for use by a disk jockey in quickly matching the beat of successive music selections using two turntables and a technique for matching the start of each beat, in a "no-pressure" environment, in as much time as required to accurately match the speed of the switchover. The position of the speed control at a the proper transition speed for a current musical selection as well as for a following musical selection is displayed for each of the corresponding turntables. These numbers are recorded on a "program form" to be used as a reference during the actual "real-time" club or disco performance.
