The portion of the pressed-together material which initially blocks the string port hole is removed after molding so that the string port holes extend through the frame. Alternatively, the mold elements cause the prepreg tube to follow a serpentine shape, thereby defining string port holes which are open alternately along the top and bottom surface of the frame. A pair of cover rings may be secured to the top and bottom racquet surfaces to cover the open sides of the string port holes.Type: GrantFiled: October 20, 2006Date of Patent: May 3, 2011Assignee: Prince Sports, Inc.Inventors: Roberto Gazzara, Mauro Pinaffo, Michele Pozzobon, Mauro Pezzato

Patent number: 7931839Abstract: A method of manufacturing a structure using a single, hollow primary tube, preferably of a composite material, wherein ports are bonded to the walls of the hollow tube through aligned holes on opposite sides of the hollow tube. The ports improve the stiffness, strength, aerodynamics, and aesthetics of the structure.Type: GrantFiled: April 21, 2008Date of Patent: April 26, 2011Assignee: Prince Sports, Inc.Inventors: Stephen J. Davis, Mauro Pezzato, Mauro Pinaffo, Roberto Gazzara, Michele Pozzobon

Patent number: 7919036Abstract: A process for preweakening the inside of an automotive trim piece cover layer of various constructions by use of a laser beam so as to enable formation of an air bag deployment opening in the trim piece formed at the time the air bag deploys. The laser beam impinges the inside surface of the cover to form a groove scoring or spaced perforations to form a preweakening pattern. A robot arm may be used to move a laser generator so as to form the preweakening pattern. The laser beam can be controlled in accordance with sensed conditions to achieve accurate preweakening, and may also be used to trim substrate panels and to perform other cutting operations.Type: GrantFiled: December 16, 2002Date of Patent: April 5, 2011Inventors: David J. Bauer, John W. Bauer, Jr., legal representative

Publication number: 20110039063Abstract: Disclosed is a process for continuous perforation of fabrics that comprise thermoplastic fibers. The process utilizes a combination of heat and pressure to perforate fabrics where the shape. size, and distribution of the individual fabric perforations is define solely by the design of the pattern embossing roll, In particular, the top side of the individual embossing points are not flat but rather have a raised peripheral edge so that the actual fabric contact area of the bond points is much less than total area circumscribed by each bond point. The small ratio of fabric contact area to total bond area concentrates the thermal and compressive forces in the embossing nip and allows a large perforation to be cut out of a fabric moving at high speed through the perforation nip.Type: ApplicationFiled: October 10, 2007Publication date: February 17, 2011Inventors: Samuel Charles Baer, Jay Darrell Gillespie, David D.

Publication number: 20110024941Abstract: In one embodiment a method for creating a molded-in-color vehicle panel is provided. The mold may have at least first and second mold members, each having a forming surface for forming a portion of the vehicle panel. One mold member may translate relative to the other to collectively receive a heated resin with a molded-in-color to form the vehicle panel. The resin may be formed into a solid molded-in-color interior vehicle panel. After allowing the resin to partially cool, an aperture may be formed by punching through in the molded-in-color resin with a punch.Type: ApplicationFiled: October 14, 2010Publication date: February 3, 2011Applicants: FORD GLOBAL TECHNOLOGIES, LLC, I-FUSION TECHNOLOGIES, INC.Inventors: Michael Alan Samluk, LaRon Brown, Stanley Staniszewski, Richard Jerome Roberts

Patent number: 7879276Abstract: A method and apparatus for a composite stringer. A method is used for manufacturing a hollow composite stringer. Foam is formed with a mandrel installed into the foam. A composite material and the foam is laid up onto a tool in a form of a stringer. The composite material and the foam in the form of the stringer is cured to form a cured stringer. The mandrel from the foam is removed to form the hollow composite stringer.Type: GrantFiled: November 8, 2007Date of Patent: February 1, 2011Assignee: The Boeing CompanyInventors: Juan C. Guzman, Douglas A. McCarville, Daniel M. Rotter, Barry P. Van West

Publication number: 20110009965Abstract: The present invention relates to improved biomedical implantable material comprising a plurality of pores, of which one or more of the pores are interconnected below the surface of the material. The improved biomedical implantable material may be used in biomedical implant devices such as orthopedic implants, spinal implants, neurocranial implants, maxillofacial implants, and joint replacement implants. The present invention also relates to a method of preparing an improved biomedical implantable material, comprising subjecting an implantable material to a pore-forming treatment and optionally further subjecting the material to a surface-modifying treatment. The biomedical implantable material may be used in other applications, which as applications where two surfaces are contacted and bonding between the surfaces is required.Type: ApplicationFiled: April 5, 2010Publication date: January 13, 2011Inventor: Sreeramamurthy ANKEM

Patent number: 7867425Abstract: A plastic closure includes a shell having a base wall with a skirt for securement to a container finish and a lip that extends radially inwardly from the skirt at a position adjacent to and spaced from the base wall. A liner is compression molded in situ against the base wall, and between the base wall and the lip. The lip has a plurality of circumferentially spaced passages that extend through the lip for venting air during compression molding of the liner.Type: GrantFiled: August 11, 2004Date of Patent: January 11, 2011Assignee: Rexam Closure Systems Inc.Inventor: Joseph M.
