Publication number: 20020182352Abstract: A three-dimensional, multi-layer plastic product that is resistant to damage caused by environmental factors such as heat, chemicals, desiccants, oxygen, and/or weather is disclosed. The multi-layer product includes an engineering resin layer affixed to a commodity resin layer. The engineering resin layer of the multi-layer film may be directly fused to the commodity resin or post-consumer regrind layer. Alternatively, the engineering resin layer may be tied to the commodity resin or post-consumer regrind layer through the use of one or more adhesive and/or tie layers. The commodity resin layer may be manufactured from an economical polymer material such as a polypropylene, polyethylene, polystyrene or post-consumer regrind.Type: ApplicationFiled: May 23, 2002Publication date: December 5, 2002Inventors: Michael R. Mitten, Elena Y. Sapatova, John F. Travers, Gregory S. Floyd

Publication number: 20020171172Abstract: The present invention involves a process that includes injecting a potting compound such as an epoxy through a hollow portion (2B) of the central mandrel (2) and onto the inner layer(s) of a multi-layered fiber bundle (3) and through the outside of the bundle and onto the outer layer(s) of the bundle. By potting through the central mandrel (2), the potting compound distributes evenly throughout the inner fibers of the bundle (3). The steps may be sequentially or simultaneously. Preferably it is done as a two-step process, with the first step being to apply the potting compound through the central mandrel (2) and onto the inner fibers first. The second step is to pot around the outer layer of the fiber bundle (3) to finish the process. The resultant product is also disclosed.Type: ApplicationFiled: May 10, 2002Publication date: November 21, 2002Inventor: Paul Lowell

Publication number: 20020158371Abstract: A method is provided for manufacturing a painted plastic component such as painted air bag covers, side cladding or exterior bumpers, which includes a painted film sheet and a one-piece thermoplastic elastomeric structural carrier. A bottom contact surface of the film sheet bonds with a front contact surface of the structural carrier by diffusion between the contact surfaces thereof within a mold cavity of an injection mold separate from the mold cavity of a vacuum mold which is utilized to vacuum-mold the film sheet to form the desired painted plastic component.Type: ApplicationFiled: April 24, 2002Publication date: October 31, 2002Applicant: Patent Holding CompanyInventors: Larry J. Winget, Darius J. Preisler, Jason T. Murar

Publication number: 20020142127Abstract: A process for forming an injection molded article including multiple appliques. The process generally includes the steps of: positioning in a mold a first applique including a edge; positioning in the mold a second applique including a terminating end; abutting the second terminating end against the edge in a non-overlapping, substantially perpendicular configuration; injection molding a thermoplastic resin around the appliques to form an article. Because the first and second appliques do not overlap, they will not separate from one another over the life of the injection molded article. Accordingly, multiple applique articles formed according to the process of the present invention maintain their structural integrity and are resistant to warping, peeling and/or separation of the appliques from one another.Type: ApplicationFiled: March 30, 2001Publication date: October 3, 2002Inventors: Victor D. Hansen, Aron I. Palmer, Eric L. Seath

Publication number: 20020135091Abstract: A female mold for plastic sanitaryware manufacture has an open top to promote improved air escape from the mold as resinous backing resin fills the mold in order to reduce the number of gas inclusions within the backing material after it is cured. The female mold also provides thermal insulation for the curing backing material to permit better curing and to reduce the potential for delamination in the finished product. A production fixture is equipped with a gas impermeable lid for selective contact with the female mold, after the air has been expelled from the mold, in order to control undesirable styrene emissions.Type: ApplicationFiled: January 22, 2001Publication date: September 26, 2002Inventors: Hiram Rivera, Dan Spiecher

Patent number: 6454977Abstract: A continuous paste making process for lead acid batteries that includes the steps of mixing water with a lead oxide, reaction an acid with the lead oxide in a mixture to produce lead acid compounds, and forming a paste including interlocking lead acid crystals from the lead acid compounds, where the mixing, reacting, and crystal forming steps occur in an extrusion apparatus. The method also includes the step of extruding the paste from the extrusion apparatus into a grid where the paste is dried to form a battery plate of the lead-acid battery.Type: GrantFiled: March 6, 2000Date of Patent: September 24, 2002Assignee: Delphi Technologies, Inc.Inventors: Wellington Y.
