Patent number: 7390448Abstract: A process for dispersion spinning non-melt-processible fluoropolymer fiber in which a mixture of an aqueous dispersion of non-melt-processible polytetrafluoroethylene or modified polytetrafluoroethylene fluoropolymer particles and an aqueous solution of matrix polymer is formed. The non melt-processible particles have an SSG of less than about 2.40. The aqueous dispersion contains an aliphatic alcohol ethoxylate nonionic surfactant having a 20% residuals temperature determined by thermogravimetric analysis (TGA) of less than about 290° C. and is essentially free of surfactants containing aromatic groups. The dispersion has a fluorinated surfactant content of less than about 300 ppm. The mixture is extruded into a coagulation bath containing a concentration of ions which coagulate the matrix polymer to form an intermediate fiber structure. The intermediate fiber structure is sintered to decompose the matrix polymer and coalesce.Type: GrantFiled: July 28, 2006Date of Patent: June 24, 2008Assignee: E.I. du Pont de Nemours and CompanyInventors: Devin Flowers, Clay Woodward Jones, Robert John Cavanaugh

Patent number: 7390449Abstract: A method of manufacturing ceramic bodies comprising the steps of: preparing a ceramic sheet; forming through holes in the ceramic sheet, each of the through hole forming at least one part of the contour of each ceramic bodies; and cutting the ceramic sheet into pieces of ceramic bodies. The ceramic sheet can be a single ceramic sheet or a laminate of ceramic sheets. The method of manufacturing ceramic bodies further comprises a step of forming a recess in the ceramic sheet, or pressure molding or partially removing of the ceramic body, as required. The manufacturing method provides inexpensive production of small ceramic elements having a complicated shape and extremely smooth surfaces with less uneven filling and nonuniform density.Type: GrantFiled: November 6, 2001Date of Patent: June 24, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akihiko Ibata, Michio Oba, Toshihiro Yoshizawa

Patent number: 7390450Abstract: A process for producing a fire resistant polycarbonate composition comprises preparing an aqueous solution of a flame retardant salt; and compounding the aqueous solution of the flame retardant salt with a polycarbonate composition to form the fire resistant polycarbonate composition. The process reduces the level of haze, color and inclusions compared to fire resistant polycarbonate compositions compounded with the same flame retardant salt in solid form.Type: GrantFiled: June 7, 2002Date of Patent: June 24, 2008Assignee: General Electric CompanyInventors: Theodorus Lambertus Hoeks, Adrianus A. M. Kusters

Patent number: 7390452Abstract: The invention is directed to an apparatus and methods for electrospinning composite fibers including polymeric material and mesoporous molecular sieve material. The methods include in one aspect electrospinning fibers from a conducting solution to which a high voltage electric current is applied. The apparatus includes in one aspect one or more conducting solution introduction devices for providing a quantity of conducting solution, the conducting solution introduction devices being electrically charged thereby establishing an electric field between the conduction solution introduction devices and a target, and means for controlling the flow characteristics of conducting solution from the conducting solution introduction devices.Type: GrantFiled: March 10, 2003Date of Patent: June 24, 2008Assignee: Board of Regents, The University of Texas SystemInventors: Kenneth J. Balkus, Jr., John P. Ferraris, Sudha Madhugiri

Patent number: 7390453Abstract: A container and closure package in that includes a container having a body, a finish wall extending from the body with at least one external thread, a circular throat at an axial edge of the finish wall remote from the body and having a lesser inner diameter than the finish wall, and a pour spout extending axially from the throat at greater inner diameter than the throat. The container body, finish wall, throat and pour spout are of integrally blow molded construction as formed, with the inside diameter of the throat being optionally reamed as required for sealing engagement with the closure. The closure has a base wall, a peripheral outer skirt extending from the base wall with an internal thread for receipt over the external thread on the container finish wall, and an internal skirt extending from the base wall and spaced radially inwardly from the outer skirt for sliding plug-sealing receipt within the throat, with the pour spout being disposed between the inner and outer skirts of the closure.Type: GrantFiled: August 4, 2006Date of Patent: June 24, 2008Assignee: Graham Packaging Company, L.P.Inventors: William W. Brecheisen, John W. Safian

Patent number: 7390454Abstract: A thermoforming methodology for laminated thermoplastic sheets which preserves the class “A” finish and high gloss thereof. A thermoformer has a vacuum box component which includes a mold, and a pressure box component which is selectively sealable in relation to the vacuum box component. A heated laminated thermoplastic sheet is placed in the thermoformer, the class “A” side thereof facing away from the mold, and the thermoformer sealed. Vacuum is applied to the vacuum box component and simultaneously air pressure is applied to the pressure box component, including application of chilled compressed air, resulting in forming of the sheet on the mold and controlled cooling of the sheet which preserves its class “A” finish and high gloss.Type: GrantFiled: August 19, 2004Date of Patent: June 24, 2008Assignee: General Motors CorporationInventors: Catherine A. Ostrander, Steven J. Schmidt, Charles Calvin Mentzer, Jr., Michael A. Szymberski, Charles K. Buehler
