Abstract

Conventional x-ray analysis apparatus employ a simple clip to hold the specimen, under analysis, in the x-ray window. The difficulty with such an arrangement resides in the fact that all specimens are not planar and, therefore, cannot readily be positioned by the clip arrangement. Moreover,in using such a clip arrangement, the plane of the specimen cannot be adjusted.

X-Ray Drawer Elevator

Conventional x-ray analysis apparatus employ a simple clip to hold the specimen, under analysis, in the x-ray window. The difficulty with such an arrangement resides in the fact that all specimens are not planar and, therefore, cannot readily be positioned by the clip arrangement. Moreover,in using such a clip arrangement, the plane of the specimen cannot be adjusted.

In the x-ray drawer positioning scheme shown, an arrangement is provided for adjusting the elevation of a specimen under analysis and wherein the specimen is not required to be mounted on the specimen platform, by clips or the like, in a planar arrangement but rather can be analyzed in its natural state, by embedding it in wax, or the like, for setting it upon the specimen platform for positioning. The platform may be coated with a mucilage to accommodate the holding of the specimen which may be embedded in a suitable potting compound, or mounted on a substrate The positioning apparatus, mounted in the x-ray holder drawer, includes a base support member which houses a Z adjustment screw and a pair of alignment rods on each side of the screw. A pair of tension springs act to hold the specimen platform against the Z adjustment screw while the platform is stabilized by the pair of alignment rods, one of which is shown. The Z adjustment screw acts to adjust the plane of the specimen while the set screw, shown in contact with an arm extending from the left side of the base support,...
