摘要: In one aspect of the present invention, a high impact resistant tool has a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem formed in the base end of the carbide segment opposite the front end is press fit into a bore of a steel body. The steel body is rotationally fixed to a drum adapted to rotate about its axis.

摘要: In one aspect of the invention, a wear resistant assembly has at least one hard insert disposed within a recess formed within a surface. A hard material substantially surrounds the hard insert and is also disposed within the surface. The hard material is separated from the insert by an intermediate material softer than both the insert and the hard material.

摘要: In one aspect of the invention, a high impact resistant tool having a superhard bonded to a cemented metal carbide substrate at a no n-planar interface. The superhard material has a substantially pointed geometry with a sharp apex having 0.050 to 0.125 inch radius. The superhard material also has a 0.100 to 0.500 inch thickness from the apex to the non-planar interface. The diamond material comprises a 1 to 5 percent concentration of binding agents by weight. The tool further comprises a central axis which intersects the interface between the diamond material, substrate, and the radius of curvature.

摘要: The present invention includes a piston valve for charging and discharging a first fluid chamber. The piston valve includes a piston shaft and a ring comprising a seal element. The piston shaft has a first end and a second end with the first end including a counter bore having at least one vent. The ring is disposed within a cylinder and the seal element is disposed intermediate the piston shaft and the ring. The piston valve may be used for intensification purposes such as in a high pressure high temperature hydraulic cartridge.
