Abstract: A method for coating a metallic substrate includes applying a powder coating composition to a majority of a surface of the metallic substrate, and applying an autodepositable coating composition to less than the majority of the surface of the metallic substrate. According to a preferred embodiment, the powder coating composition is applied to at least one continuous surface of the metallic substrate, while the autodepositable coating composition is applied to at least one discontinuous surface, such as an edge, of the metallic substrate.

Abstract: A modular paint line includes a plurality of modular stations positioned in series and defining a transportation path. At least one of the modular stations includes an immersion tank. The paint line also includes means for moving at least a first carrier in a forward transport direction along the transportation path while maintaining at least a second carrier in a stationary position, above the immersion tank, along the transportation path. The aforementioned means includes an article transportation system having a plurality of carrier tracks.

Abstract: Apparatus and methods for dissolving a gas into a liquid comprises a saturation tank, a high pressure liquid pump in fluid communication with the tank, and a pressurized gas source in communication with a regulated gas head space of the saturation tank. The saturation tank comprises a pressure vessel for containing the liquid and has a regulated gas head space above the liquid, contains at least one liquid spray nozzle that permits passage of liquid into the pressure vessel, and an outlet for the liquid containing dissolved gas. Upon passing the gas-containing liquid into a second fluid, the gas is released in the form of microbubbles. The microbubbles aid in flocculation of suspended particles and promote dissolution of the gas in the second fluid. Preferred gases for use with the apparatus are oxygen, air, and ozone. Anticipated uses include treatment of rivers, streams, and ponds in natural or industrial settings, as well as smaller scale applications.
