Abstract: An adjustable mattress foundation comprises a lower frame, an upper frame, and a plurality of movable supports attached to the lower frame or the upper frame. The movable supports are adapted to maintain the upper and lower frames in spaced apart relation and are further adapted to permit vertical movement of the upper frame into a plurality of spaced apart relations relative to the lower frame.

Abstract: A method and apparatus for the descaling of metal surfaces without the use of caustic substances is provided. The apparatus includes a first and second blast heads containing nozzles that spray high velocity jets of media at a scale covered continuous sheet of steel. The continuous sheet of steel is advanced into an abrading station containing a pair of brush assemblies that include stainless steel bristled brushes. The stainless steel brushes engage the surface of the sheet of steel and abrade away the cracked scale, leaving a surface clean of scale. The surface produced is pH neutral and therefore resists additional corrosion and does not require oil coatings, or other protective treatments. Eliminating these steps makes for a faster, more robust process and saves considerable cost.
