    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.

    摘要: A high impact resistant pick in a holder having a super hard 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 bolster. A bore is formed in a base end of the carbide bolster generally opposed to the front end. A steel shank being fitted into the bore of the bolster at a bolster end of the shank, and a portion of the shank is disposed within a bore of the holder at a holder end of the shank.

    摘要: An impact tool for use with a driving mechanism, the impact tool including an impact tip formed from a super hard material and having an apex and an attachment end, with the attachment end being bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded in turn to the front end of a cemented metal carbide bolster. The carbide bolster is securable against an outer surface of a driving mechanism through a press fit.

    摘要: In one aspect of the present invention, a high-temperature, high-pressure press apparatus has a cartridge assembly adapted for connection to a unitary frame. An anvil is attached at a front end of a cylindrical body of the cartridge and a hydraulic chamber within the body is adapted to apply axial pressure to the anvil. A threaded end of the anvil is adapted for mating with a threaded inside diameter of a borehole disposed within a wall of the frame. A radial compression element disposed around an outer diameter of the body is adapted to limit radial expansion of the body proximate the hydraulic chamber. At least one mechanism is attached to the radial compression element; the at least one mechanism being adapted to preload the threaded connection between the cartridge assembly and the frame.
