Patent number: 7625510Abstract: Composite tooling is fabricated with low cost dry fabrics and a neat resin instead of expensive prepregs. Dry, three-dimensional woven joint preforms are placed on a dry tool substrate and dry, 3D preforms are also placed between pre-cured egg crate-like junctions. The entire tool substrate and substrate-to-support structure joints are then resin-infused simultaneously through the use of rota-molded tooling aids, providing an additional reduction in cost. Tight control of resin content and distribution with vacuum infusion is thereby provided. This process eliminates the primary cause of structural weakness and cooling distortion, which typically occur at the attachment interface when existing methods are used. The preforms provide significantly greater pull-off strengths at interfaces than do hand-laid tie plies. Issues with tool surface durability are addressed through the use of ceramic-filled face coat.Type: GrantFiled: November 29, 2005Date of Patent: December 1, 2009Assignee: Lockheed Martin CorporationInventors: Todd H.

Patent number: 7625516Abstract: A manufacturing method for a sheet molded body having a desired three dimensional shape and an excellent quality of the design, which has no crease, by uniformly expanding a decorated sheet prior to molding, and closely contacting the decorate sheet to the surface of a male die. In the manufacturing method, the pressure at the front side of the decorated sheet is lowered relative to that at the back side. An arm means is then moved towards the decorated sheet from the back side of the decorated sheet so that the decorated sheet is inverted by increasing the pressure at the front side relative to that at the back side. The decorated sheet is then three dimensionally formed along the surface of the male die by, while pressing the male die from the back side and moving the arm means backwards, increasing the pressure at the front side.Type: GrantFiled: August 31, 2007Date of Patent: December 1, 2009Assignee: C.I. Kasei Company, LimitedInventors: Takahiro Aida, Takeo Kobayashi, Yukio Ueda, Hiroshi Fujita

Patent number: 7625517Abstract: A cooling system for the distribution and collection of a fluid coolant in a metallurgical vessel used in the processing of molten materials. The cooling system comprises a distribution system including an intake manifold, a plurality of headers attached to the intake manifold, and a plurality of distribution dispensers positioned along each header. A collection system, including a collection manifold, is positioned to collect the fluid coolant. The distribution dispensers are positioned to direct the fluid coolant towards the collection manifold and utilize the majority of the kinetic energy contained within the coolant to direct the coolant towards the collection manifold.Type: GrantFiled: November 19, 2007Date of Patent: December 1, 2009Assignee: Systems Spray-Cooled, Inc.Inventors: Mark Thomas Arthur, J. Michael Campbell, Troy D. Ward

Patent number: 7625520Abstract: A manufacturing method for producing metal matrix composite (MMC) sheets without intermediate process losses associated with extrusion and rolling edge cracks. The method results in theoretical sheet yield rates from the initial MMC billet of up to 100%, compared to 30 to 60% yield rates for prior-art manufacturing processes. The methods in this invention comprise the following processes: (a) preparing a MMC powder mixture; (b) preparing a frame and a billet consolidation tool; (c) loading and compacting the MMC mixture to form a framed MMC compact; (d) consolidation of the framed MMC compact to form a framed MMC billet; (e) preparing the framed billet to be a framed roll-preform; and (e) rolling the framed roll-preform to MMC sheet.Type: GrantFiled: November 18, 2003Date of Patent: December 1, 2009Assignee: DWA Technologies, Inc.Inventors: Jack Y. Peng, Mark R. van den Bergh, William C. Harrigan

Patent number: 7625521Abstract: A bit body formed of a mixture of matrix material and superabrasive powder and including pockets lined with superabrasive-free matrix material, and a method for forming the same, are provided. The pockets are shaped to receive cutting elements therein. The superabrasive-free matrix material enhances braze strength when a cutting element is brazed to surfaces of the pocket. The method for forming the drill bit body includes providing a mold and displacements. The displacements are coated with a mixture of superabrasive free matrix-material and an organic binder. The mold is packed with a mixture of matrix material and superabrasive powder and the arrangement heated to form a solid drill bit body. When the solid bit body is removed from the mold, pockets are formed by the displacements in the bit body and are lined with the layer of superabrasive-free matrix material. The superabrasive material may be diamond, polycrystalline cubic boron nitride, SiC or TiB2 in exemplary embodiments.Type: GrantFiled: June 5, 2003Date of Patent: December 1, 2009Assignee: Smith International, Inc.Inventors: Saul N. Izaguirre, Thomas W. Oldham, Kumar T. Kembaiyan, Gary R. Chunn, Anthony Griffo, Robert Denton, Brian White
