Abstract: Apparatus and method for treating medical implants are provided. The apparatus may include a vessel having a treatment chamber with an inside surface, an outside surface, an entrance, a plurality of fluid passages passing from the outside surface to the inside surface, and a compressible fluid supply line coupled to at least one of the fluid passages. In this embodiment, passages may be positioned and sized to create a buffer zone of compressible fluids between the inside surface of the treatment chamber and a medical implant placed therein. The method may include placing a first medical implant into a treatment chamber having inside surfaces, retarding the first medical implant from contacting the inside surfaces of the treatment chamber by injecting compressible fluid into the treatment chamber, injecting a therapeutic into the treatment chamber, and removing the first medical implant.

Abstract: Methods and apparatus for recycling office waste paper and the like of the type having ink and laser print particles coated thereon. The waste paper is simultaneously pulped and ink particles dispersed by kneading the waste paper in the form of a high solids content aqueous mixture or sludge. After the simultaneous pulping and dispersing, no additional dispersion step is needed to form deinked paper stock The high solids content aqueous mixture or sludge is diluted and forwarded to wet deinking separation devices such as a froth flotation unit or the like. The thus treated pulp is washed and results in the formation of a high quality pulp stock ready for bleaching and/or paper making procedures.
