Patent number: 7077937Abstract: A large surface area electrode well-suited to electrochemical applications is produced by winding many turns of a metallic fiber tow on to a sheet metal rectangle. In the preferred embodiment, an anode that can be used to purify water by electrochemical production of hydroxyl free radical is made by winding titanium fiber tow on to a rectangular substrate made of titanium sheet, and applying a suitable multilayered electrocatalytic coating. Made of other metals, an electrode of this description can also serve as the cathode of an electrochemical cell, or as a battery plaque.Type: GrantFiled: July 3, 2003Date of Patent: July 18, 2006Inventors: Oleh Weres, Henry Edward O'Donnell

Patent number: 6974634Abstract: A finished laminate is provided. The laminate includes an imperforate metal layer having a metallic surface, and a metallic felt layer having a first surface attached to the metallic surface and an exposed second surface facing away from the metallic surface. Also provided is multi-layer tubing including a thermally conductive metal layer having a metallic surface, and a substantially thermally non-conductive, metallic felt layer having an outer felt layer surface attached to the metallic surface and an exposed inner felt layer surface. The metal layer and the metallic felt layer collectively form a laminate configured as a substantially cylindrical structure with the metallic felt layer positioned radially inward of the metal layer. In certain embodiments, the metal the laminate has opposite side edge portions overlapping and coupled to one another at a coupling portion, without a thermally conductive path through the coupling portion.Type: GrantFiled: November 5, 2003Date of Patent: December 13, 2005Assignee: Material Sciences CorporationInventors: Craig Cless, Gregory Corda

Patent number: 6854171Abstract: The present invention provides a method for producing a bending-resistant, elongated body, preferably a shaft or beam. The invention is characterized in that an elongated blank is produced having at least one cavity extending essentially along the entire length of the blank, the inner surface of which cavity is at a distance from the mass center of the blank seen in a section at right angles to its longitudinal axis and that affixed in the cavity is a fiber composite body with an outer surface essentially congruent with the inner surface of the cavity and that majority of the fibers in the fiber composite body both extend essentially parallel to the longitudinal axis of the elongated blank and are elongated along the whole of its length. The invention also relates to an arrangement produced according to the method.Type: GrantFiled: January 28, 2002Date of Patent: February 15, 2005Assignee: Megtec Systems Amal ABInventors: Jervant Ulf, Max Krogager

Publication number: 20040225175Abstract: A dual lumen catheter system for the positioning of a radioactive material for therapeutic radiation treatment of the body is disclosed. The dual lumen catheter includes a guidewire lumen and a blind lumen provided for introduction of a radiation source wire. The dual lumen catheter provides the advantage that the radiation source wire does not contact body tissue thereby eliminating the need for sterilization of the wire for reuse. Also disclosed are a radiation source wire having a tapered distal end of the wire core such that radioactive material and other components of the source wire can be applied to the outer surface thereof without exceeding a predetermined maximum outside diameter. Also disclosed is a source train cask for use with the catheter system and radiation source wire of the invention. The source train cask permits convenient handling and feeding of the radiation source wire without exposure of the medical personnel to radiation.Type: ApplicationFiled: June 3, 2004Publication date: November 11, 2004Inventors: Michael R. Moody, Anthony D. Coon, Richard A. Brauckman, Jack C. White

Publication number: 20040128776Abstract: A tensioning element (1), especially for the suspension of building components, is provided with a number of wires (3) arranged approximately in parallel forming a wire cable (2). These wires (3) are anchored at each end in an end piece (6) absorbing the tensile forces exerted on the wire cable. The end piece (6) is at least partly provided with a plastic deformable sheath (6b) which serves to house one end of a wire cable, where this sheath (6b) is compressible with the end of the wire cable. This enables rapid anchoring of the wire cable in the end piece and this guarantees a high breaking load.Type: ApplicationFiled: October 14, 2003Publication date: July 8, 2004Inventor: Bernhard Eicher

Patent number: 6735866Abstract: Method for manufacturing elements made from composite material using the co-bonding technique, in which uncured elements (preformed beams (2)) are bonded onto another cured element (the skin (3)) with multiple thickness changes, using a rigid tooling made of invar used for support and positioning during the curing process. Each element is made with preimpregnated material using automated tape laying. The preform of the beams (J-section) is obtained by hot forming of flat laminates. The final curing and bonding to the precured skin (co-bonding) is performed using a direct vacuum bag in an autoclave. A flat development of the vacuum bag is performed, it is traced with a numerical control machine and it is made prior to being placed on the tool. For large surfaces with difficult access the final adjustment is performed with the tool and the part in a vertical position, due to the ergonomic difficulties involved in working on certain areas of same. The invention is applicable to the field of aeronautics.Type: GrantFiled: February 12, 2002Date of Patent: May 18, 2004Assignee: Airbus Espana, S.L.Inventors: Pedro Nogueroles Vi{overscore (n)}es, Aquilino Garcia Garcia, Carlos Cerezo Pancorbo
