摘要： An apparatus for compressing a workpiece is disclosed. The apparatus has a die to receive the workpiece in powdered or other form. An abutment holds the workpiece in a fixed position against the application of force, while a hydraulic cylinder is positioned to exert force against the die in the direction toward the abutment. A pump feeds hydraulic fluid to the hydraulic cylinder, and a pressure control valve is coupled to the hydraulic cylinder to control the maximum pressure in the hydraulic cylinder. The pressure control valve has a sealing member, a seat which engages the sealing member with the sealing member closing the outlet, a spring which urges the sealing member towards the seat, closing the outlet, and a backing member putting the spring under compression by maintaining a distance between the backing member and the seat. A stepping motor is rigidly mounted with respect to the seat. The stepping motor has a shaft which may be advanced towards and away from the valve seat whereby the degree of compression on the spring may be adjusted.

摘要： A monochromator of the Czerny-Turner type includes an entrance slit, a collimating mirror for receiving light output by the entrance slit, a planar grating for receiving light reflected by the collimating mirror, a focusing mirror for receiving light reflected by the grating, and an exit slit for receiving light focused by the focusing mirror. Light generally proceeds from the entrance slit to the collimating mirror, form the collimating mirror to the grating, from the grating to the focusing mirror and from the focusing mirror to the exit slit. The improvement comprises the use of a single toroidal collimating mirror in the system in combination with a spherical focusing mirror.
