Publication number: 20100272923Abstract: A method and apparatus are disclosed for improving densification of porous substrate using a film boiling process. In particular, the disclosed method and apparatus permit more complete densification of a substrate (i.e., densification closer to the surface of the substrate) by selectively providing a sort of barrier that reduces cooling of the surface of the substrate being densified caused by contact with the relatively cool boiling liquid precursor of the densifying material, such as carbon. In particular, contact between the substrate and the liquid precursor is reduced using one or both of physical barriers (such as a mesh material) or structures that promote the formation of an insulating gaseous layer between the substrate and the liquid precursor (such as a plate closely spaced apart from the surface of the porous substrate). The barrier is moved into operational position before the applied power level increases sharply (as is known) near the end of the film boiling densification process.Type: ApplicationFiled: April 22, 2010Publication date: October 28, 2010Applicant: MESSIER-BUGATTIInventor: Arnaud Fillion

Publication number: 20100247808Abstract: A method of depositing a solute (34) on a metal thread (4), comprising the steps of: depositing a liquid solution (3), formed from a volatile solvent and said solute (34), on the thread (4); and then rapidly raising the temperature of the thread (4) to a temperature above the vaporization temperature of the solvent so as to vaporize the solvent placed in contact with the surface of said thread (4) and to form vapour bubbles (32) which, by expanding, generate a pressure pulse that ejects the liquid (33) remaining on the periphery of the thread.Type: ApplicationFiled: June 5, 2008Publication date: September 30, 2010Applicants: SOCIETE DE TECHNOLOGIE MICHELIN, Michelin Recherche et Technique S.A.Inventors: Henri Hinc, Guy Chevrel

Patent number: 7744798Abstract: When integrally producing a lamp holder, which is provided with a lamp body and a lens portion, by using a mold-sliding injection system, a lamp holder having a reflection surface formed on the interior surface thereof is produced. A fixed mold is provided with a vacuum deposition apparatus, wherein a lamp holder having a reflection surface is produced by a reflection surface forming process, which is provided between a primary injection process for molding a lamp holder and a lens portion and a secondary injection process for integrating the lamp holder and the lens portion by matching the same together, for vacuum-depositing the reflection surface on the interior surface of the lamp holder.Type: GrantFiled: May 17, 2004Date of Patent: June 29, 2010Assignee: Mitsuba CorporationInventors: Motosuke Ishizawa, Takao Umezawa

Patent number: 7704553Abstract: A process for depositing nanometer-sized metal particles onto a substrate in the absence of aqueous solvents, organic solvents, and reducing agents, and without any required pre-treatment of the substrate, includes preparing an admixture of a metal compound and a substrate by dry mixing a chosen amount of the metal compound with a chosen amount of the substrate; and supplying energy to the admixture in an amount sufficient to deposit zero valance metal particles onto the substrate. This process gives rise to a number of deposited metallic particle sizes which may be controlled. The compositions prepared by this process are used to produce polymer composites by combining them with readily available commodity and engineering plastics. The polymer composites are used as coatings, or they are used to fabricate articles, such as free-standing films, fibers, fabrics, foams, molded and laminated articles, tubes, adhesives, and fiber reinforced articles.Type: GrantFiled: February 23, 2007Date of Patent: April 27, 2010Assignees: National Institute of Aerospace Associates, The United States of America as represented by the Administrator of NASAInventors: Kent A. Watson, Michael J. Fallbach, Sayata Ghose, Joseph G. Smith, Donavon M. Delozier, John W. Connell

Publication number: 20100098551Abstract: The present invention relates to a method for coating components of a gas turbine, in particular for producing a wear-resistant, temperature, oxidation and/or corrosion-resistant protective coating on the component, wherein the protective coating is made of at least one solder film or slurry coating, which is connected to the corresponding region of the component by means of an inductive high-temperature soldering method. The bonded connection between the component and the solder film or slurry coating disposed on the component is achieved by locally heating the component in the region of the solder film or slurry coating to be applied, and simultaneously heating the solder film or slurry coating by means of thermal energy generated and emitted by at least one induction amplifier, wherein the induction amplifier is disposed between the inductor and the component in the region of the solder film or slurry coating.Type: ApplicationFiled: February 28, 2008Publication date: April 22, 2010Applicant: MTU Aero Engines GmbHInventors: Herbert Hanrieder, Alexander Gindorf, Hans Pappert
