  • Patent number: 8052765
    Abstract: Contoured solid polycrystalline superabrasive material such as twist drill tips and endmill flank segments can be formed by preparing a precursor mold having a plurality of shaped openings each corresponding to a predetermined shape. A specially prepared charge feed can be placed into the shaped openings to form a charged precursor. The charge feed can include a substantially homogeneous mixture of superabrasive source particulates, sintering binder, and optional inorganic bonding medium. A loaded reaction cup-assembly including the charged precursor can be subjected to a pressure, temperature and time sufficient for sintering and formation of the contoured polycrystalline superabrasive material. Reduced finishing steps and increased tailorability of grade and quality of final polycrystalline products can be readily achieved.

  • Patent number: 7585342
    Abstract: A polycrystalline superabrasive composite tool can be produced using high pressure high temperature processes allowing for increased thermal resistance, wear resistance and toughness of abrasive tools, and additionally allowing for increased effective thickness of abrasive tools. A polycrystalline superabrasive compact can include a support substrate and a superabrasive polycrystalline layer having a diffusion bridge embedded therein that includes a carbide former. Additionally, a working layer can be attached adjacent to the superabrasive polycrystalline layer and opposite the support substrate to form a drill bit sandwich segment. The diffusion bridge matrix of the present invention allows for a new welding phase at each interface between the superabrasive polycrystalline layer and support substrate and between the polycrystalline layer and the metal working layer, thus eliminating delamination failure at the interfaces.

  • Patent number: 7553344
    Abstract: A new industrial thermally stable polycrystalline diamond (TSP) is disclosed and described as a replacement of natural as well as synthetic diamond grit in concrete cutting, grinding, polishing, and surface-set grinding or core bit drilling applications. Conventional diamond is too strong and brittle for self-sharpening and polishing and has a lower thermal stability inferior to the industrial standard for high temperature tool segment bonding. TSP grits can be tailor-made having unique properties as well as an engineered shape of grits over naturally or synthetically produced diamond grits. The TSP grits have a high thermal stability of up to 1200° C. and are self-sharpening. Further, economical production of coarse TSP grit size up to 1-2 mm from 50/60 mesh size in almost any preferred shape such as blocky, round, hexagonal, thin elongated, spherical, needle like, and any desirable tailor-made shaped etc can be realized.

  • Patent number: 7435377
    Abstract: A weldable ultrahard insert can include an ultrahard working layer and a weldable metal layer metallically bonded with the working layer. The ultrahard working layer can be any ultrahard material such as PCD, PCBN, metal carbide, ceramic, diamond, or the like. The weldable ultrahard inserts can be formed by charging a reaction vessel with ultrahard materials, including precursors thereof, and placing a weldable metal layer in the reaction vessel with an optional intermediate layer. The assembly can be subjected to a pressure and a temperature sufficient to metallically bond the weldable metal layer to the ultrahard material. The weldable layer is formed as part of the insert in situ which facilitates subsequent welding of the insert to a tool substrate without risking damage to the ultrahard material.

  • Publication number: 20080106198
    Abstract: A display apparatus includes a plasma display panel (PDP) and a filter having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes an external light shield having a first base unit and first pattern units. The first pattern units absorb external light from the viewer side and are substantially parallel to a first axis. The filter includes an electromagnetic interference (EMI) shield overlapping the external light shield. The EMI shield includes a second base unit and second pattern units. The second pattern units are conductive and substantially parallel to a second axis. An interior angle between the first axis and the second axis can be within a range of 40 to 50 degrees.
