Abstract: A device for removing molecular pollutants from exhaust gasses has a cylindrical chamber and a rotating probe extending axially through the length of the chamber. A spark pin projects from the outer surface of the probe, and a train of high voltage electric pulses is applied across a cylindrical contact around the inner wall of the chamber and the spark pin. The train of high voltage pulses cause a pattern of sparks to form in the chamber which reduce molecular pollutants to non polluting compounds.

Abstract: A multipurpose gymnastic apparatus comprises a frame unit, a pulley unit, and a load carrying unit. The frame unit is composed of a ladder frame having a front end on which a dual-purpose pushing and rotating device is mounted, a chair set and a leg stretching device. The pulley unit comprises a plurality of independent ropes running through the pulleys and having free ends connected with the pushing and rotating device and the leg stretching device. The load carrying unit is capable of being lifted and lowered by the ropes. The pushing and rotating device comprises two wheel fitting members, two arresting pieces, and a protective rod. The ropes running on the two fitting members can be actuated by the two arresting pieces to permit a chest building exercise to be done while the ropes can be pressed against by the protective rod to permit an arm building exercise to be done.

Abstract: The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

Abstract: A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.

Abstract: A method for etching a bevel edge of a substrate in a processing chamber is provided. The method includes flowing an inert gas into a center region of the processing chamber defined above a center region of the substrate and flowing a mixture of an inert gas and a processing gas over an edge region of the substrate. The method further includes striking a plasma in the edge region, wherein the flow of the inert gas and the flow of the mixture maintain a mass fraction of the processing gas substantially constant. A processing chamber configured to clean a bevel edge of a substrate is also provided.
