A rigid base portion of an applicator tip assembly is mounted into an upper rim of the cup section and liquid silicone material is poured into the volume defined in the cup section portion beneath the base portion. The silicone cures and bonds to extending elements from the base portion, providing a firm connection between the cast tip portion and the base portion. When the combined part is ready for use, the tear-away sections are removed by the user, which results in an easy ejection of the part, which can then be installed by the user in the formulation applicator.Type: ApplicationFiled: May 29, 2009Publication date: December 2, 2010Applicant: Pacific Bioscience Laboratories, Inc.Inventors: Richard A.

Patent number: 7837919Abstract: An open cell or highly porous woven composite truss utilizes fibers of carbon, glass, ceramic, or the like that are woven together in a loom. The warps or tow are woven with the wefts, while the fibers are impregnated with resin. The resin impregnation step may be performed before or after the weaving step. The truss is then cured on the loom and later may be machined as needed. A rigid foam material may be used to stabilize the shape of the truss prior to curing and while machining. The foam may be later chemically dissolved or otherwise disposed of.Type: GrantFiled: September 28, 2005Date of Patent: November 23, 2010Assignee: Lockheed Martin CorporationInventors: Slade H. Gardner, Brian T. Rosenberger

Patent number: 7833453Abstract: Process for producing an injected article to which a flocked decoration is applied that includes the production of a flocked substrate (11) based on a temporary substrate (1) covered by a temporary adhesive (2) that keeps the flock fibers (3) in place, positioning of the flocked substrate in an injection mold of the article to be produced, injection of a polymer (12) being melted in the closed mold through an injection opening (4), removal of the injected article from the mold and the peeling off of the temporary substrate (1) and the temporary adhesive (2) from the injected article, characterized in that the flocked substrate (11) is positioned in the mold so that the flock fibers (3) are oriented toward the interior of the mold.Type: GrantFiled: November 23, 2007Date of Patent: November 16, 2010Assignee: Societe d'Enduction et de FlockageInventors: Jean-Pierre Lion, Pierre Marie Congard

Patent number: 7824171Abstract: An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions.Type: GrantFiled: October 31, 2005Date of Patent: November 2, 2010Assignee: The Boeing CompanyInventors: Steven F. Hanson, Amitabh Vyas

Patent number: 7811500Abstract: The present invention relates to a method for manufacturing at least a portion of a sports racquet frame that comprises a step a) of providing a moldable tube structure containing a first inflatable bladder and a second inflatable bladder. The first and second inflatable bladders are positioned on opposite first and second regions of the moldable tube structure. At an intermediate region, the tube structure comprises one or more cross channels, which pass through the moldable tube structure. The method according to the present invention comprises also a further step b) of inserting said tube structure inside a mold forming a mold cavity of a desired shape. Mold members are inserted into the cross channels of the tube structure, so that the outer surface of the mold member faces the inner surface of the corresponding cross channel.Type: GrantFiled: February 15, 2007Date of Patent: October 12, 2010Assignee: Prince Sports, Inc.Inventors: Roberto Gazzara, Mauro Pinaffo, Michele Pozzobon, Mauro Pezzato

Patent number: 7811486Abstract: Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.Type: GrantFiled: August 19, 2004Date of Patent: October 12, 2010Assignee: 3M Innovative Properties CompanyInventors: Naimul Karim, Darin J. Meyertholen, Robert M. Biegler, Kevin M. Cummings, Lance C. Gore, James R. Kvitrud, Robert W. Peterson, Daniel T. Scott

Publication number: 20100252957Abstract: A method of compacting material such as but not limited to cathode material for electrochemical cells. A mixture is inserted into a die cavity and the mixture is compacted into a disk shape by the action of a first plunger pressing down on the material and a second plunger pressing upwardly on the material. Flashing of material during ejection of the disk from the die is prevented by fitting a polymeric sleeve around the outer surface of the first plunger. The sleeve flexes to bulge outwardly and does not enter the die cavity during compaction of material and returns to its original position during ejection of the compacted disk from the die. Contact between the disk and sleeve prevents flashing during ejection. Alternatively, a polymeric seal ring is placed around the outer surface of the first plunger. The disk presses against the seal ring preventing flashing of material during ejection.Type: ApplicationFiled: April 1, 2009Publication date: October 7, 2010Inventors: Albert A. Andrews, Robert D.
