  • Diamond-enhanced carbide cutting elements, drill bits using the same, and methods of manufacturing the same
    Patent number: 9328565
    Abstract: Embodiments for diamond-enhanced carbide cutting elements and drilling apparatuses that include a diamond-enhanced carbide material are disclosed. Embodiments of methods for manufacturing such articles are also disclosed. The diamond-enhanced carbide cutting elements disclosed are at least partially enclosed by a refractory metal structure from a refractory metal can assembly used in the fabrication of the diamond-enhanced carbide cutting element. The diamond-enhanced carbide cutting elements disclosed herein have greater abrasion resistance than tungsten carbide, and a greater toughness than polycrystalline diamond cutters.

  • Synthetic gasket material
    Patent number: 6338754
    Abstract: A synthetic gasket material and the method for make such is described. This invention is specifically adapted for use in high-pressure, high-temperature presses. This material is made from a compacted, granulated and dried mixture of talc, garnet, and sodium silicate. This composition provides an alternative to the use of natural pyrophyllite as the material for gasket components, thereby reducing the cost of the materials. This composition can be pressed to net or near net geometry, thereby generating less waste. Moreover, this composition provides more consistency for the gasket components. Furthermore, this material has improved thermal insulator properties, thereby leading to lower power consumption used in the high-pressure, high-temperature presses.

  • Surface geometry for non-planar drill inserts
    Patent number: 6196340
    Abstract: A cutting element insert is provided for use with drills used in the drilling and boring through of subterranean formations. This new insert has a modified diamond surface shape having ridges, facets and/or other discontinuities on the cutting surface topography, formed on or about an otherwise non-planar shape, such as spherical, hemispherical, conical or the like. This modified diamond layer shape provides increased cutting stress at the diamond/rock interface, thereby causing the rock to fail with less over all drilling energy being required, while simultaneously introducing little additional stresses to the cutter or insert.
