Abstract: The present invention is a golf cup cutter sharpener. The sharpener consists of one or more grinding wheels affixed in a rigid housing. The grinding wheels are cylindrical metal elements covered by a removable, and thus replaceable, abrasive surface. The wheels are belt driven, and powered by a standard electrical motor. The grinding wheels are aligned according to the geometry of the sharpener. The angle of the wheels is chosen so as to provide the proper angle of grinding to create a sharp cutting edge. If two wheels are utilized, the wheels are positioned to contact two non-adjacent scallops of the sharpener. A mandrel holds the cup cutter in place while the sharpening operation is taking place.

Abstract: A diamond-anvil, high-pressure cell having an apertured steel gasket interposed between the opposed diamonds is lowered into a liquified hydrogen bath at cryogenic temperatures. After the liquid hydrogen permeates the cell through the viewing apertures an initial sealing pressure is applied to the cell by a remotely operated threaded arrangement sufficient to prohibit escape of the liquified hydrogen from the aperture in the steel plate which is closed by the opposed diamonds. The cell is then typically removed from the liquified hydrogen bath and introduced into a lever type pressure applicator to further increase the pressure on the hydrogen at room temperature for the observation of its effects through suitable apertures in the cell and to convert the same to solid form.
