| 1. A high-temperature, high-pressure press apparatus, comprising:
a cartridge assembly adapted for connection to a unitary frame;
an anvil at a front end of a cylindrical body of the cartridge and a hydraulic chamber within the body adapted to apply axial
pressure to the anvil;
a threaded end of the anvil being 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 and adapted to limit radial expansion of the body
proximate the hydraulic chamber; and
at least one mechanism 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.
