  • Publication number: 20120298578
    Abstract: Filtration systems (40) utilize a pre-treatment method to cause scale formation to occur on particles (94) in the fluid stream (96) rather than on the filter surface and may also destroy microorganisms in the fluid stream. More specifically, but not limited to, a filtration device can be a filtration membrane, such as spiral wound filtration membrane (60), that utilizes an open feed spacer (80), such for example an embossed or printed pattern on the membrane, to create a thin feed spacer channel which replaces a conventional feed spacer mesh material. System (40) further utilizes a treatment device (54) to enable a pulsed power, magnetic, electro-magnetic, electro-static, or hydrodynamic fluid treatment scheme to condition particles in the fluid stream (96) such that scale forming elements precipitate (94) on to the particles in the fluid stream rather than on the filtration surfaces.

  • Patent number: 6045686
    Abstract: A process for the delacquering and detinning of a metal substrate is presented comprising the fully electrochemical removal of both an outer polymeric coating and an inner tin coating from a metal substrate. The disclosed method provides a clean metal substrate, and results in wastes which are easily disposed of with minimal cost and minimal environmental impact. In one embodiment, the present invention comprises a one-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate in a single electrolyte bath through electrolytic removal of both the polymeric and tin layers from the metal substrate. An electrically conductive container having the electrolyte bath therein acts as an anode in the process, and the removed tin is plated out on the cathode. In another embodiment, the present invention comprises a two-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate.

  • Patent number: 4363722
    Abstract: A process and apparatus is disclosed for treating titanium machining scrap to remove both magnetic and non-magnetic high density inclusions, particularly bits or pieces of tungsten carbide broken from the cutting tool or tools associated with the scrap. In the process and apparatus a major portion of the undesired high density inclusions are removed by the novel use of an air separator, particularly one having an inclined, vibrating, air-conducting deck onto which the work product is fed and through which an upward current of air is blown. One or more magnetic separators are also used in advance of a final x-ray inspection station. The overall efficiency of the process and apparatus is such that a high percentage of initial input material is converted to high quality material passing the x-ray inspection and suitable for use in making rotating aircraft parts or other parts subjected to severe service demands.
