Patent number: 11911936Abstract: Aspects hereof provide methods for molding a single-phase solution comprised of a polymer composition and a gas. The polymer composition and the gas are maintained under pressure during the molding operation to prevent a cellular structure from being formed by the dissolved gas in the polymer composition coming out of solution. The mold cavity in which the single-phase solution is introduced for molding purposes is pressurized to a mold pressure that is sufficient to maintain the single-phase solution as a single-phase solution as the mold cavity is filled. Subsequent to filling the mold cavity with the single-phase solution under pressure, the resulting article may be exposed to a reduction in pressure causing the entrapped gas to form a cellular structure.Type: GrantFiled: November 30, 2020Date of Patent: February 27, 2024Assignee: NIKE, Inc.Inventors: Jeffrey E.

The fourth, known as the “Cast & Roll” system, whereby a pre-tube, obtained directly from the melting, is laminated by a triple roller system. Finally, the innovative manner whereby a continuous vertical casting manufactures pre-tubes continuously, directly from the melt. The four first systems are widely used in the industry to manufacture what is known as a “pre-tube” that usually has a diameter of 60 mm or higher, which we shall name “old pre-tube”.

Patent number: 8211214Abstract: The present invention is directed toward a method for reducing pattern distortions in imprinting layers by reducing gas pockets present in a layer of viscous liquid deposited on a substrate. To that end, the method includes varying a transport of the gases disposed proximate to the viscous liquid. Specifically, the atmosphere proximate to the substrate wherein a pattern is to be recorded is saturated with gases that are either highly soluble, highly diffusive, or both with respect to either the viscous liquid, the substrate, the template, or a combination thereof. Additionally, or in lieu of saturating the atmosphere, the pressure of the atmosphere may be reduced.Type: GrantFiled: February 5, 2008Date of Patent: July 3, 2012Assignees: Molecular Imprints, Inc., Board of Regents, The University of TexasInventors: Frank Y. Xu, Niyaz Khusnatdinov

Patent number: 8206637Abstract: An apparatus comprises a deformable platform and a laser delivery system. The deformable platform has a surface capable of changing to conform to a shape of an object as the object is being manufactured during a sintering process. The laser delivery system is capable of sintering powder on the deformable platform to manufacture the object.Type: GrantFiled: October 14, 2008Date of Patent: June 26, 2012Assignee: The Boeing CompanyInventors: David Michael Dietrich, Richard L. Eason

Patent number: 8163212Abstract: The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.Type: GrantFiled: July 14, 2003Date of Patent: April 24, 2012Assignee: Kuraray Co., Ltd.Inventors: Naohiko Uchiumi, Noriyuki Kida, Hiroyuki Shimo, Kaoru Ikeda

Publication number: 20120007268Abstract: A method for manufacturing a semiconductor is disclosed. A mold is providing having an interior defining a planar capillary space. A measure of precursor is placed in fluid communication with the capillary space. The precursor is then melted, and the melted precursor is allowed to flow into the capillary space. The melted precursor is then allowed to cool to form a semiconductor.Type: ApplicationFiled: September 19, 2011Publication date: January 12, 2012Applicant: Mossey Creek Solar, LLCInventor: John Carberry
