  • Patent number: 7169296
    Abstract: A collapsible water treatment digester includes a flexible bladder, a frame, and a plurality of filter plates. The flexible bladder is movable from a collapsed position wherein the bladder is folded into a substantially flattened state to an expanded position wherein the bladder forms a water treatment chamber. The frame is connected to the bladder so as to support the bladder in the expanded position. The filter plates are disposed within the water treatment chamber of the bladder so as to cause a substantial portion of the solids from a wastewater stream introduced into the water treatment chamber to produce a reconditioned water stream dischargeable from the bladder.

  • Publication number: 20050241438
    Abstract: The material and method for making a textured flexible sheet of a precious metal involves using a precious metal paste, having a consistency whereby the precious metal paste may be brushed onto a textured surface, to create a thin and flexible precious metal veneer. The precious metal paste is applied to a textured surface and allowed to dry, becoming a veneer sheet of a precious metal material having a flexible, leather-like consistency. Once dried, the precious metal material is removed from the substrate in the form of a flexible precious metal veneer having a textured surface. The veneer retains the properties of a precious metal material from which it was made, including amount of shrinkage and range of firing temperatures. The precious metal veneer can be formed into, or applied to, an article of jewelry or artwork or another article, and sintered to become a piece of fine precious metal.
