摘要： A rigid composite structure includes a tubular body made from a metallic material and having a first bore formed therein along a longitudinal axis, and one or more segments formed from a super hard material disposed within the first bore. Each segment has a hole formed in the center thereof, and the segments may be positioned end-to-end and adjacent to one another to align the center holes about the longitudinal axis and form a second bore. The segments can be held under compression within the first bore of the tubular body. The segments may be made of super hard materials such as natural diamond, synthetic diamond, polycrystalline diamond, single crystalline 10 diamond, cubic boron nitrate or other superhard composite materials which exhibit low thermal expansion rates and are generally chemically inert. The resultant rigid composite structure may possess higher tolerances to high pressures and high temperatures within the second bore.

摘要： In one aspect of the invention, a pick comprises a carbide bolster disposed intermediate an impact tip and a shank assembly. The impact tip comprises a superhard material bonded to a carbide substrate, and the tip is bonded to the bolster opposing a base of the bolster. The shank assembly comprises a central axis, a first end that protrudes into a cavity formed in the base of the bolster, and also an inducible attachment mechanism disposed proximate the first end. The inducible attachment mechanism is adapted to attach the shank assembly to the carbide bolster and restrict movement of the shank assembly with respect to the carbide bolster. The attachment mechanism may restrict movement of the shank assembly in a direction parallel to the central axis.

摘要： In one aspect of the invention, a cartridge assembly is adapted for connection to a frame of a high pressure, high temperature press having a front end with a back up intermediate and coaxial with an anvil and a piston. The back up has an anterior end proximate the anvil and posterior end proximate the piston. The cartridge assembly has a hydraulic system adapted to apply axial pressure to the back-up through the piston to axially move the front end with respect to a cartridge body. The assembly also has a centralizing assembly with a rod rigidly attached to the cartridge body at a first end and a second end adapted to slide within a peripheral bore formed in the front end.

摘要： In one aspect of the invention, a tool has a working portion with at least one impact tip brazed to a carbide extension. The carbide extension has a cavity formed in a base end and is adapted to interlock with a shank assembly of the cutting element assembly. The shank assembly has a locking mechanism adapted to interlock a first end of the shank assembly within the cavity. The locking mechanism has a radially extending catch formed in the first end of the shank assembly. The shank assembly has an outer surface at a second end of the shank assembly adapted to be press-fitted within a recess of a driving mechanism. The outer surface of the shank assembly has a coefficient of thermal expansion of 110 percent or more than a coefficient of thermal expansion of a material of the driving mechanism.
