Abstract: A method for cleaning a surface of an aluminum or aluminum alloy body by immersing the surface in a basic aqueous electrolyte formed essentially from dissolved trisodium phosphate, flowing DC current through the electrolyte and the body for cleaning, and then removing the body from the electrolyte. An additional cleaning step, which may include ultrasonic cleaning, may be performed to remove loose matter adhering to the body after the electrolytic cleaning.

Abstract: A foundry mixture for making molds used for molding cast metal parts includes foundry sand, a non-aqueous binder, and a cleaning agent that includes calcium oxide. Residual foundry mixture remaining on the cast part after removal from the mold is removed by electrolytic cleaning of the cast part.

Abstract: A method for cleaning a surface of an aluminum or aluminum alloy body of coatings, contaminants, dirt, or the like by immersing the surface in a basic aqueous electrolyte containing carbonate ions, connecting the body directly to the negative terminal of a DC current source and flowing DC current through the body. After a time, the flow of DC current is stopped and the surface is removed from the electrolyte. The surface is then rinsed off to remove the coating, dirt, contaminants, or the like from the surface.

Abstract: A method for cleaning a surface of a metal or metal alloy body by immersing the surface in a basic aqueous electrolyte containing carbonate ions, and flowing DC current through the body to make the body anodic. After a time, the flow of DC current is stopped and the surface is removed from the electrolyte. The surface is then rinsed off to remove dirt, corrosion, coatings, and the like from the surface.

Abstract: An apparatus and method for generating a Contact Glow Plasma Discharge in an electrolyte such as 7% K2CO3. A Shrouded Toroidal Anode is partially submerged in the electrolyte directly above a Flat Torus Cathode (totally submerged in the electrolyte), spaced approximately 50 mm apart, and the two electrodes are arranged in a concentric manner. A potential difference is applied from the cathode to the anode causing gas to be formed on the cathode. This is followed by a contact glow plasma being formed on the surface of the cathode and electromagnetically confined by a Spheromark formed by the configuration of the electrodes. This confinement of the plasma prevents a plasma arc from consuming the anode, which in turn allows for the application of 12,000 Watts and the occurrence of “non-linear electron resonance heating”. The effects of nonlinear series resonance increase the total power dissipation by factors of 2-5 for low pressure capacitive plasmas.

Abstract: A method for cleaning residual mold material from a sand casting, the mold material comprising sand, a binder, and an electrolytic material, the method comprising exposing the residual mold material to an electrolytic solution; and subjecting the residual mold material to an electric current.

Abstract: An electrolytic cell for the generation of a plasma field in an electrolyte that heats the electrolyte forms part of a closed-loop heat transfer device, the electrolytic cell fluidly connected to a heat exchanger. A plasma electrode and a second electrode form part of the flow path of electrolyte from the tank to the heat exchanger. The electrolyte must flow through or along the electrodes when flowing from the tank to the heat exchanger.

Abstract: An electrolytic cell for the generation of a plasma field in an electrolyte that heats the electrolyte forms part of a closed-loop heat transfer device, the electrolytic cell fluidly connected to a heat exchanger. A plasma electrode and a second electrode are mounted on a tubular insulating member that forms part of the flow path of electrolyte from the tank to the heat exchanger. The electrolyte must flow through the electrodes when flowing from the tank to the heat exchanger.

Abstract: A method and apparatus for cleaning conductive and non-conductive bodies using a basic aqueous disodium phosphate and sodium bicarbonate cleaning solution. The outside surfaces of a metallic or non-metallic body are cleaned by spraying or brushing the cleaning solution on to body, or by placing the metallic body in electrical contact with the cleaning solution, an anode and a cathode (either of which may be the body itself) and flowing DC current from the anode to the cathode and thus through the chemical solution, thereby causing the cleaning solution to electrolytically clean the body. The DC current is provided by an inverter power source. The body may be immersed in the electrolytic cleaning solution or the electrolytic cleaning solution may be sprayed onto the body.

Abstract: A snowmobile drive assembly includes an engine mounted on a frame by vibration isolation mounts and having an output shaft connected, by means of a flexible coupling, to a first shaft which is rotatably supported on the frame by a first pair of axially spaced bearings. A variable speed primary clutch is mounted on the first shaft between the first pair of bearings and is connected, via a drive belt, to a variable speed secondary clutch mounted on a second shaft disposed parallel to the first shaft and rotatably mounted on the frame by a second pair of bearings.
