Embodiments of the present invention include a press base assembly, a strengthening ring for use with press bases and related methods. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.

The invention relates to a powder press having preferably a plurality of stamps (11) which are movable for a transverse press in a feed housing (10), said stamps partially delimiting a hollow chamber of a matrix in the feed housing (10) and being able to be coupled to a press device (40) by one connector piece each. An adjustable positioning means, which is formed from a wedge arrangement (20) having a stop surface (22) and placed crosswise to the moving direction of the stamp (11) is allocated to the respective stamp (11) for determining the pressing position thereof. Said wedge arrangement (20) comprises at least one wedge (21), which is adjustable crosswise to the moving direction of the stamp (11) and has the stop surface (22), which contacts a stop surface (11″) at the stamp (11). Such a wedge arrangement can achieve very accurate pressing positions of the stamp, first of all, and extremely stable positioning of the stamp to be pressed with high pressure, second of all.

A cartridge assembly comprising a chamber for containing hydraulic fluid, an intensifier element capable of reciprocating in the chamber and displacing the hydraulic fluid responsive to a drive means acting on the intensifier element, and a piston capable of reciprocating in the chamber and being displaceable responsive to a change in the pressure of the hydraulic fluid. The cartridge assembly is configured so that when the pressure in the fluid increases responsive to a first force being applied by the drive means on the intensifier, the hydraulic fluid will exert a second force on the piston, the second force being greater than the first force; the mass of the hydraulic fluid being substantially conserved within the cartridge assembly.

A press, an automated loading system for a press and related methods are provided including a loading system having a first assembly configured to carry a reaction cell to an anvil of a press base and a second assembly configured to assist in positioning and orientating the reaction cell on the anvil. In one embodiment, the first assembly may include a trolley displaceable along a guide member to carry the reaction cell to the anvil. The first and second assemblies may each include guide members that are displaceable relative to the anvil that are configured to position the reaction cell at a desired location and orientation on the anvil. In one embodiment, each of the guide members include arms that engage distinct sides of a cubic reaction cell. A clearing mechanism may also be incorporated to clear the surface of the anvil during operation of the system.

The present invention provides a multi-anvil machine, more specifically, a multi-anvil cubic machine that generates substantially hydrostatic pressures and high temperatures inside an industrial reaction chamber. In said chamber materials such as diamonds, cubic boron nitride and similar materials. These conditions are attained in a stable and efficient manner. The generation of force is produced by hemispherical pistons having a short travel path and housed in semi-spherical chambers. The number of mobile components has been reduced in order to simplify and facilitate the assembly during each working cycle.
