Patent attributes
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.
