  • SPARK PLASMA SINTERED POLYCRYSTALLINE DIAMOND
    Publication number: 20180208511
    Abstract: The present disclosure relates a spark plasma sintered polycrystalline diamond and methods of spark plasma sintering leached polycrystalline diamond. Spark plasma sintering produces plasma from a reactant gas found in the pores left by catalyst removal from leached polycrystalline diamond. The plasma forms diamond bonds and/or carbide structures in the pores, which may produce polycrystalline diamond that is has a higher impact strength than the leached polycrystalline diamond or other improved properties.

  • SPARK PLASMA SINTERED POLYCRYSTALLINE DIAMOND COMPACT
    Publication number: 20180200789
    Abstract: The present disclosure relates to polycrystalline diamond covalently bonded to a substrate by spark plasma sintering and methods of covalently bonding polycrystalline diamond and a substrate. Spark plasma sintering produces plasma from a reactant gas found in the pores in the polycrystalline diamond and, optionally, also the substrate. The plasma forms carbide structures in the pores, which covalently bond to the substrate.

  • MECHANICALLY STRENGTHENED BOND BETWEEN THERMALLY STABLE POLYCRYSTALLINE HARD MATERIALS AND HARD COMPOSITES
    Publication number: 20180163322
    Abstract: The strength of the bond formed by a braze material between a polycrystalline hard material and a hard composite may be physically strengthened. For example, a method of physical strengthening may include etching a bonding surface of a polycrystalline material body to produce a synthetic topography on the bonding surface of the polycrystalline material body, the bonding surface opposing a contact surface of the polycrystalline material body; and brazing the bonding surface of the polycrystalline material body having the synthetic topography to a bonding surface of a hard composite using a braze material.

  • Chimaeric surrogate light chains (SLC) comprising human VpreB
    Patent number: 9963716
    Abstract: The present invention relates inter alia to improvements in the production of chimaeric antibodies in non-human transgenic vertebrates such as mice and rats bearing one or more chimaeric antibody transgenes. In particular, the invention provides for improved non-human vertebrates and cells in which VpreB has been species-matched with the variable region of the chimaeric antibodies. Also, embodiments also provide for species-matching of the entire surrogate light chain for efficient pairing with chimaeric heavy chains during B-cell development in vivo in a non-human transgenic vertebrate setting.

  • Catalyst material extraction from polycrystalline diamond tables
    Patent number: 9878957
    Abstract: Catalyst extraction from polycrystalline diamond table may be achieved by treating with a halogen (in the gas phase or dissolved in a nonpolar organic solvent) to convert the catalyzing material to a salt. Then, polar organic solvents may optionally be used to leach the salt from the polycrystalline diamond table. The polycrystalline diamond (with the salt of the catalyzing material present or at least partially leached therefrom) may be brazed to a hard composite substrate to produce a cutter suitable for use in a matrix drill bit.
