Patent number: 6461461Abstract: A process for producing multi-layer game ball products includes the steps of extruding an inner layer precursor as a parison in a partial melt state, forming an outer layer, introducing the inner and outer layers into a mold and expanding the parison within the mold to form the multi-layer game ball product. The outer layer may take the form of pre-cut panels vacuum supported in the mold and an intermediate layer may be provided for dimensional stability in the product. Subsequent to expanding the parison a filler such as foam may be injected into the center space for forming a core.Type: GrantFiled: June 28, 2001Date of Patent: October 8, 2002Assignee: Spalding Sports Worldwide, Inc.Inventor: Thomas J.

Patent number: 6461463Abstract: Processes for producing a holographic material involve producing the holographic image on a polished, substantially smooth surface and then transferring the holographic image to a substrate. A metallic coating is applied to a smooth surface of a printing element to provide a coated surface, the coated surface is embossed to provide the holographic image, and the holographic image is transferred to a substrate via a bonding material, thereby producing the holographic material. The holographic material may be used to provide a decorative cover for an object or item, such as a floral grouping or a potted plant.Type: GrantFiled: August 8, 2000Date of Patent: October 8, 2002Assignee: Southpac Trust International, Inc.Inventor: Donald E. Weder

Patent number: 6461464Abstract: A colinear laminate honeycomb panel permits the use of two or more different materials to form a single panel. In this manner, a retractable cover for an architectural opening may be formed that has a different appearance depending upon which side of the panel is being viewed. The resultant panel is formed by attaching a plurality of elongated precursor tubular cells, wherein each precursor tubular cell itself comprises at least two strips of material held in proximity to one another by a common carrier strip.Type: GrantFiled: May 9, 2000Date of Patent: October 8, 2002Assignee: Hunter Douglas Inc.Inventor: Paul G. Swiszcz

Patent number: 6461465Abstract: An apparatus for manufacturing a liquid crystal panel in which two substrates are faced to each other with spacers interposed therebetween, applied with heat pressure in an overlapped condition, and adhesive arranged between the two substrates is cured for fixing, characterized in that at least of a pair of pressurizing plates for applying pressure to the two substrates is a graphite plate and in that upper and lower pressurizing plates are made to be of different rigidity. The graphite plate of low rigidity is made to stick to the substrate, and shifts between substrate can be prevented while securing uniformity in gap between substrates.Type: GrantFiled: January 23, 2001Date of Patent: October 8, 2002Assignees: Advanced Display Inc., Mitsubishi Denki Kabushiki KaishaInventors: Masahiko Tada, Kohei Adachi, Hiroki Toyoshima, Susumu Kono, Kazuo Yoshida, Yoshihiro Kashiba, Yoshimi Kinoshita

Patent number: 6461466Abstract: In a transcribing method for making a steering wheel rim of an automobile using water pressure and a printed transcribing sheet having a different pattern or brightness at the left and right sides, two symmetrical printed transcribing sheets are prepared using computer graphics for fitting to the steering wheel rim. In a first transcribing step, a first sheet is transcribed using a masking method. The surface where the first transcribing is performed is cleaned and masked, and the steering wheel rim is rotated by 180°. In a second transcribing step, on the surface of the steering wheel where no transcribing has been performed, a second printed transcribing sheet is transcribed to the steering wheel rim.Type: GrantFiled: March 30, 2000Date of Patent: October 8, 2002Inventor: Youn-soo Cho

Patent number: 6461467Abstract: Medical dressings are disclosed that include multiple exposed pressure sensitive adhesives. One of the pressure sensitive adhesives includes a bioactive agent and is substantially contact transparent. In some embodiments, all of the adhesives are substantially contact transparent. Also provided are methods of manufacturing the medical dressings. By providing multiple exposed pressure sensitive adhesives, the pressure sensitive adhesive formulations can be varied to provide desired properties in different areas of the dressing. A pressure sensitive adhesive that exhibits relatively high tack to skin may be provided around the periphery of the dressing while a pressure sensitive adhesive incorporating a bioactive agent is provided in the center of the dressing. Alternatively, a higher tack pressure sensitive adhesive may be provided at two opposing sides of the dressing with a bioactive adhesive located in between the opposing portions of higher tack adhesive.Type: GrantFiled: April 23, 2001Date of Patent: October 8, 2002Assignee: 3M Innovative Properties CompanyInventors: Todd A. Blatchford, Steven B. Heinecke, Donald H. Lucast, Donald G. Peterson

Patent number: 6461468Abstract: A method and apparatus for making a dripper line by feeding the dripper units (DU) into the extruded tube (ET) at a linear velocity, at the instant of their initial contact with the inner surface of the tube, which is greater than the linear velocity of the inner surface of the tube where initially contacted by the dripper units. The dripper units are fed between a track (10) within the extruded tube and a moving backing surface (20) externally of the tube spaced from the track to determine the final thickness of the extruded tube and the dripper unit welded thereto.Type: GrantFiled: November 29, 2000Date of Patent: October 8, 2002Inventor: Amir Cohen
