Patent number: 9868639Abstract: There has been a problem that wrinkles easily occur on a carbonaceous film produced by the use of a continuous production method and on a graphite film obtained by heat-treating the carbonaceous film. In the present invention, heating treatment is carried out on a polymeric film while applying pressure to the polymeric film in the film thickness direction with the use of a continuous carbonization apparatus. This makes it possible to obtain a carbonaceous film and a graphite film in which wrinkling is reduced.Type: GrantFiled: September 19, 2013Date of Patent: January 16, 2018Assignee: KANEKA CORPORATIONInventors: Satoshi Katayama, Yusuke Ohta, Takashi Inada, Makoto Kutsumizu, Yasushi Nishikawa

Patent number: 9663879Abstract: Disclosed is a method of strengthening existing structures containing the following steps. An existing structure made of concrete, steel, timber, masonry to be reinforced and a reinforcing sheet are provided, where the reinforcing sheet contains an alternating arrangement of reinforcement zones and slitting zones. The reinforcement zones contain unidirectional strengthening fibers in the warp direction of the reinforcement sheet and the slitting zones have an absence of strengthening fibers. The reinforcement sheet is slit through the slitting zones and the reinforcement zones are adhered to the existing structure.Type: GrantFiled: August 20, 2015Date of Patent: May 30, 2017Assignee: Milliken & CompanyInventors: Gregg J. Blaszak, Gregory A. Norton, Pradipkumar Bahukudumbi

Patent number: 9144171Abstract: Techniques for efficient routing of wires and electrical components within a device are disclosed. A wire can be routed, for example, in the space between two battery cells (or other components/structures) with the use of a bracket inserted between the cells to provide structural support. Electrical tape surrounding a battery may be breached to expose a cavity between distinct battery cells. In some embodiments, multiple brackets may be inserted between the cells, creating a trough through which a wire or other component may be routed. After routing a wire through the trough, another electrical part or housing may be fixed above the battery cells. One example case includes a first electrical component placed within the bracket, and a second electrical component routing in a divergent path to the first electrical component external to the bracket, wherein the first and second electrical component have a common start and end point.Type: GrantFiled: January 24, 2013Date of Patent: September 22, 2015Assignee: Nook Digital, LLCInventors: Karla Robertson, Nina Joshi

Patent number: 8980062Abstract: An industrial fabric, belt or sleeve and a method of making the fabric, belt or sleeve are disclosed. The industrial fabric, belt or sleeve is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, around two rolls in a side-to-side manner in which a gap between adjacent edges is formed. A second material, for example a gap filler material, is placed between the adjacent edges, and the adjoining edges are joined by melting the filler material, strips of polymeric material, or both. The gap filler material can have a specific cross-sectional shape corresponding to the gap.Type: GrantFiled: December 26, 2012Date of Patent: March 17, 2015Assignee: Albany International Corp.Inventors: Jonas Karlsson, Anders Nilsson, Mikael Danielsson, Marcus Backstrom
