Abstract
In one aspect of the present invention, a cartridge assembly for connection to the frame of a high-pressure, high-temperature press comprises a front end comprising a back-up intermediate and coaxial with an anvil and a piston, the anvil comprising a proximal end in contact with the back-up and a distal end that forms part of a pressurized chamber within the frame, the back-up comprising a proximal end comprising a first diameter proximate an interface with a distal end of the piston, and a distal end comprising a second diameter proximate an interface with the proximal end of the anvil, the back-up comprising one or more circumferential reliefs disposed on the first diameter.
