Patent number: 7014883Abstract: A method for forming a composite structure is disclosed. The method includes four steps. Step one calls for applying a primer (104) to a surface (102) of a tool (100). Step two requires applying a coating (106) to primer (104). Step three calls for curing primer (104) and coating (106). The last step calls for forming the composite structure on tool (100). More specifically, primer (104) may be a powdered primer, and coating (106) may be a powdered fluorinated organic compound.Type: GrantFiled: January 14, 2004Date of Patent: March 21, 2006Assignee: Northrop Grumman CorporationInventors: Ernie R. Silva, Jerry W. Brimer, Sandra J. Stash

Patent number: 7011869Abstract: A process for coating a substrate is provided which includes the following steps: (a) applying a waterborne base coat composition to a surface of the substrate; (b) applying infrared radiation at a power density of 1.5–30.0 kW/m2 and a first air stream simultaneously to the base coat composition such that a pre-dried base coat is formed upon the surface of the substrate; and (c) applying a second air stream in the absence of infrared radiation to the base coat composition such that a dried base coat is formed upon the surface of the substrate. Various embodiments of the invention are disclosed including continuous, batch, and semi-batch processes, which may include additional process steps, such as subsequent application of a topcoat. The process may be used to coat a variety of metal and polymeric substrates, for example, those associated with the body of a motor vehicle.Type: GrantFiled: September 2, 2003Date of Patent: March 14, 2006Assignee: PPG Industries Ohio, Inc.Inventor: Donaldson J.

Patent number: 6998155Abstract: The invention relates woven and knit materials with an incorporated particulate solid and to a process for producing woven materials incorporated with a particulate solid. The process comprises: entraining a particulate solid in a gaseous carrier; disposing one face of a woven material in the path of a stream of said gaseous carrier and entrained particulate solid; maintaining a pressure drop across the woven material from said one face to the other face of said material, thereby to obtain a woven material with at least some of the entrained particulate solid in the gaseous carrier; and fixing the incorporated particulate solid.Type: GrantFiled: May 23, 2001Date of Patent: February 14, 2006Assignee: TrapTek LLCInventors: Gregory W. Haggquist, Richard A. Mellor

Patent number: 6991830Abstract: A process for the manufacturing of a decorative surface element, which element comprises a base layer and a decorative upper surface. A wetting repellent lacquer is printed in a predetermined pattern on the decorative upper surface. The wetting repellent lacquer covers only parts of the decorative upper surface. A wear layer of a UV or electron beam curing lacquer is then applied on top of the decorative upper surface which UV or electron beam curing lacquer is repelled from the parts of the surface being covered by the wetting repellent lacquer whereby a surface structure is achieved.Type: GrantFiled: November 24, 2000Date of Patent: January 31, 2006Assignee: Pergo (Europe) ABInventors: Krister Hansson, Johan Lundgren, Hakan Wernersson

Patent number: 6969546Abstract: A ceramic tile includes a ceramic core material and an oxide ceramic matrix composite (CMC), where the ceramic core material has at least one surface covered by the oxide CMC. The oxide CMC includes a ceramic fiber, with a cured metal oxide ceramic material impregnating the ceramic fiber. An exemplary embodiment of the ceramic tile provided as part of the invention further includes a tough low temperature cure coating (TLTC) which infiltrates the ceramic core surface before it is covered by the oxide CMC. The TLTC includes a cured ceramic powder together with a binder. The metal oxide ceramic material impregnating the ceramic fiber, and the TLTC are co-cured, meaning that neither is cured when the CMC is wrapped around a surface of the TLTC-infiltrated ceramic core, and a curing step is performed on both uncured ceramic materials at the same time.Type: GrantFiled: October 20, 2003Date of Patent: November 29, 2005Assignee: The Boeing CompanyInventor: Robert A. DiChiara, Jr.

Patent number: 6942900Abstract: A process for producing insulations for electrical conductors by powder coating, which results in aging which is improved compared to glass-mica or casting-resin insulation, and a powder which is suitable for such a process. The powder is applied a number of times in succession, in the form of individual layers which follow one another, until a layer thickness of ?10 mm is reached, and each of the individual layers undergoes intermediate heat curing before the next individual layer is applied. The intermediate curing of each individual layer uses a curing time which corresponds to 2-10 times the gel time of the powder used. Finally, the entire insulation undergoes final curing. The result of an electrical life test carried out on various specimens insulated with epoxy-resin powder which contains fine filler.Type: GrantFiled: December 21, 2000Date of Patent: September 13, 2005Assignee: ALSTOM Technology Ltd.Inventors: Thomas Baumann, Johann Nienburg, Jörg Oesterheld, Jörg Sopka
