Patent number: 8662879Abstract: The invention discloses a mold performing in the micro/nano imprint fabricating process, wherein the mold is utilized to imprint a pattern on a substrate via a material layer. The mold comprises an upper surface, a lower surface, a pre-determined structure and an overflow controlling device. The upper surface and the lower surface are corresponded to each other. The pre-determined structure is disposed on the lower surface of the mold. The overflow controlling device is utilized to maintain the pressure among the material layer and the substrate.Type: GrantFiled: May 25, 2011Date of Patent: March 4, 2014Assignee: National Taiwan University of Science and TechnologyInventor: Fuh-Yu Chang

Patent number: 8662880Abstract: Soluble pouches are formed on a continous motion rotating thermoforming machine having cavities in the surface of a drum into which a web of polymeric film is drawn by a vacuum to form pockets. The pockets are filled with one or more components and closed by a further web of polymeric film. Shrink-back of the polymeric film within the cavities is reduced by heating the cavities with heaters.Type: GrantFiled: May 17, 2012Date of Patent: March 4, 2014Assignee: Rideau Machinery Inc.Inventors: James Fowler, Boris Makutonin

Patent number: 8662882Abstract: The disclosure provides a golf ball mold that may produce a golf ball with a reduced gate defect. The golf ball mold may have a mold cavity having a mold chamber including a surface shaped as the inverse of a substantially hemispherical shape and a parting edge disposed along the perimeter of mold chamber. At least one gate may be disposed on the parting edge to provide a path for a cover material to be injected into the mold chamber. The gate may include a flat middle surface connected by a first side surface and a second side surface disposed opposite the first side surface. A round having a radius of curvature ranging from about 0.2 mm to about 0.5 mm may be disposed along a middle gate edge of middle surface and/or a side gate edge of one of the first side surface and the second side surface.Type: GrantFiled: March 30, 2012Date of Patent: March 4, 2014Assignee: NIKE, Inc.Inventor: Ying-Kai Wang

Patent number: 8662883Abstract: Apparatus is described for combusting exhaust gases output from a plurality of process chambers. The apparatus comprises a plurality of exhaust gas combustion nozzles (22) connected to a combustion chamber (24). Each nozzle receives a respective exhaust gas (26), and comprises means for receiving a fuel (40) and an oxidant (30) for use in forming a combustion flame within the chamber. A controller receives data indicative of the chemistry of the exhaust gas supplied to each nozzle, and adjusts the relative amounts of fuel and oxidant supplied to each nozzle in response to the received data. This can enable the nature of each combustion flame to be selectively modified according to the nature of the exhaust gases to be destroyed by that flame, thereby enhancing the destruction rate efficiency of the exhaust gas and optimising fuel consumption.Type: GrantFiled: May 3, 2006Date of Patent: March 4, 2014Assignee: Edwards LimitedInventors: Darren Mennie, Nicholas Benjamin Jones, Colin Michael Harrison
