A drive mechanism is coupled to the mold and configured to rotate the mold such that the fiber-reinforced plastic article is taken up on the mold. An energy source is operatively associated with the mold and positioned so that the partially cured fiber-reinforced plastic article is cured in a spirally wound shape as the article is taken up on the longitudinally extending mold. The pultrusion apparatus allows for continuously shaping a non-linear fiber-reinforced plastic article, obviating the need for any of the work to be done by hand, which may be labor intensive, not as highly reproducible, and potentially contaminating.Type: GrantFiled: May 29, 2001Date of Patent: January 20, 2004Assignee: University of North Carolina at Chapel HillInventors: Robert P. Kusy, Scott Zufall, Matthew Camp, Glenys Thorstenson, Brian Rucker, Hiawatha Demby, David Ruddell, Elodia Cole, Aditya Patel

Publication number: 20030183986Abstract: An apparatus and method for bonding polymeric materials is disclosed. The apparatus and method both utilize ferromagnetic materials in association with the polymeric materials to be bonded together. The polymeric materials, and the ferromagnetic material, are placed within a magnetic field, which causes hysterisis losses in the ferromagnetic field, and thus elevation in the temperature of both the ferromagnetic material and the polymeric materials to the point where the polymeric materials melt and fuse together. The ferromagnetic materials only rise in temperature to their Curie temperatures, at which point the hysterisis losses cease, and the polymeric material stops being heated. Removing the electromagnetic field allows for cooling and fusing.Type: ApplicationFiled: March 28, 2002Publication date: October 2, 2003Inventor: Jan Weber

Patent number: 6610242Abstract: A mat of polymeric fibers is treated to alter a filtration surface by the application of heat and pressure. The filtration surface is heated to a temperature sufficient to soften the fibers and pressure is applied to compact the softened fibers in order to reduce the average pore size on or at the filtration surface.Type: GrantFiled: May 14, 2001Date of Patent: August 26, 2003Inventors: Malcolm Swanson, Ken L. Parris, Winston F. Budrow, Alan Smithies

Patent number: 6599462Abstract: A method for manufacturing balloon catheters, and the catheters manufactured thereby. In accordance with the method, a workpiece comprising a tube-within-a-tube is placed within a mold, and a first region of the outer tube is distended into contact with the mold to form a seamless balloon of a desired configuration. The distension of the first region of the outer tube may be facilitated by electron beam irradiation, heating and/or longitudinal drawing of the workpiece concurrently with the introduction of a pressurized fluid into the space between the inner surface of the outer tube and the outer surface of the inner tube so as to exert the required outwardly distending pressure against the first region of the outer tube.Type: GrantFiled: July 29, 1999Date of Patent: July 29, 2003Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Manouchehr Miraki

Publication number: 20030064236Abstract: The invention relates to a multi-layered biaxially-oriented film, mainly made of a crystallizeable thermoplastic polyester and economically produceable with a high surface quality, i.e. without pinning bubbles and without electric arcing and film breaks, at production speeds of 340 m/min or higher. According to the invention the multi-layered polyester film has an average specific electrical melt resistance over its total thickness which lies within a range from 1.5×107 to 30×107 &OHgr;×cm. The invention also relates to a method of production of the film.Type: ApplicationFiled: August 24, 2001Publication date: April 3, 2003Inventors: Harald Mueller, Ursula Murschall

Patent number: 6508973Abstract: An ink jet printhead has a number of nozzles each ejecting drops of ink toward a surface. Each nozzle has a nozzle chamber at least partially defined by an apertured roof portion operatively connected to an actuator such that the actuator moves the roof portion away from the surface to be printed to eject the ink. The ink jet printhead also has a projection within each nozzle for effectively dislodging any dried ink clogging the nozzle rim, hence preventing blocking of the nozzle.Type: GrantFiled: February 15, 2001Date of Patent: January 21, 2003Assignee: Möllertech SASInventors: Andreas Beckmann, Eric Lecomte

Patent number: 6464814Abstract: A method for molding an end of a long resin molded article that is obtained by extrusion molding and has a design surface and an attachment surface extended in a longitudinal direction of the long resin molded article, and the attachment surface is attached to other parts. An end portion of the long resin molded article is heated so as to soften the end portion of the long resin molded article. The design surface of the heated end portion is pressed so as to stretch resin on a side of the design surface thereby forming an inclined surface on the end portion, whereby the end portion is inclined from the design surface at the end portion to said attachment surface at the end portion along said inclined surface. The attachment surface of the heated end portion is pressed so as to form a cavity on the attachment surface and stretch resin on a side of the attachment surface.Type: GrantFiled: January 25, 2001Date of Patent: October 15, 2002Assignee: Toyoda Gosei Co., Ltd.Inventors: Yasunobu Teramoto, Shinichi Goto, Tatsuo Ito, Hiroshi Mukai, Hiroshi Iwasaki, Masahiro Nakatani

Patent number: 6447627Abstract: A process forms lightweight molded articles by positioning inserts having gas creating substances at set positions on a matrix layer positioned between mold halves. The matrix layer with inserts is pressed into the mold cavity and sandwiched between molding material. The gas forming substances are activated to produce gas and the mold halves partially opened to allow the gas to form gas cavities at the position of the inserts. The matrix may be a film or net with gas creating substances in attached packets. Alternatively, the matrix may be developed with inserts of gas producing substances encapsulated within molding material by co-extrusion or co-injection nozzles.Type: GrantFiled: January 3, 2000Date of Patent: September 10, 2002Inventor: Georg Michael Ickinger

Publication number: 20010042945Abstract: A method and apparatus for making insignias with a raised design is capable of providing more aesthetic appearance to the insignias thus made. A base material consisting of a base sheet and a surface sheet overlaying the base sheet is prepared for making into an insignia. The base material is coating with a surface coating of decorative material. A bottom mold and an upper mold are used to press the base material to form raised design of patterns. The bottom and upper molds are coupled to a composite heating device including high-frequency induction and electric heating means for applying both high-frequency induction heat and electric heat to the base material while the upper molding is being pressed against the bottom mold. The upper mold is formed with a plurality of edge-defining blades for cutting an edge for the insignia, a plurality of pattern-defining blades for forming a pre-designed pattern on the insignia.Type: ApplicationFiled: November 2, 1998Publication date: November 22, 2001Inventor: SZE TSANG WU
