Abstract: Methods and apparatuses are provided to reduce combustion time and/or combustion temperature in an internal combustion engine. In an exemplary embodiment, intake air and oxygen-rich gas are introduced upstream of a turbofan, wherein the amount of oxygen rich gas is controlled in proportion to the engine speed.

Abstract: Systems and methods for improving the efficiency and/or reducing emissions of an internal combustion engine are disclosed. The system may comprise a tank configured to store an aqueous solution consisting essentially of water and a predetermined quantity of electrolyte. The system may further comprise a cell configured for aiding in the electrolysis of the aqueous solution, the cell may comprise a plurality of plates arranged substantially parallel to one another and the plurality of plates may be spaced substantially equidistant from an adjacent one of the plurality of plates. In exemplary embodiments, at least one seal may be located between the plurality of plates to create a substantially air tight and substantially water tight seal between adjacent ones of the plurality of plates to aid in preventing the aqueous solution located between adjacent ones of the plurality of plates from leaking out of the cell.

Abstract: A cover for a swimming pool comprises an awning of flexible waterproof sheet material having guide members secured to its longitudinal edges. A pair of side rails are fixed to the longitudinally-extending walls of the pool. The rails are of keyhole cross-section so that the guide members at the edges of the awning can slide into the side rails from their ends and slide longitudinally of the rails to secure the edges of the awning to the walls of the pool along their entire length. A shaft is mounted in a storage box formed adjacent one transverse edge of the pool so that the awning can be rolled around it for storage. Guidelines are attached to the leading edge of the awning and are joined to form a pull-line which runs back to a drum in the storage box. The drum and shaft are driven by means of an electric motor to move the awning along the pool.
