| 1. A cartridge assembly adapted for connection to a frame of a high pressure, high temperature press, comprising:
a front end comprising a back up intermediate and coaxial with an anvil and a piston;
the back up comprising an anterior end proximate the anvil and posterior end proximate the piston;
the cartridge assembly comprising a hydraulic system adapted to apply axial pressure to the back-up through the piston to
