Abstract: This invention relates to a process for the application of organic materials, such as powders, to hot dip or electroplated galvanized metal which provides a finished material with a higher level of corrosion resistance than that obtained from organic coatings on mild or black steel. Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation of the substrate is necessary as is required with existing processes on mild or black steel. Also, the invention relates to the hot dip or electroplated galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating. Hot dip or electroplated galvanized metal treated by this process leads to a uniform coating which is virtually impervious to acid, basic and salt solutions, and which will not scratch or flake off on impact.

Abstract: A slide structure for sleds for human occupancy is disclosed, and is designed to have human occupant sleds sliding down into a body of water. The slide structure has a support framework on which a plastic sheet material is provided and a water supply means supplies only a thin film of water to the upper surface of the plastic sheet material. This conserves power and water, yet the thin film provides a very low coefficient of friction, so that the sleds attain a high speed for a quiet, fast, smooth, and more exciting ride, yet with reduced wear on both the slide and sleds.
