Abstract
Abstract A combined, portable crystal mount and goniometer apparatus having built-in vertical and horizontal goniometer members, and an adjustably mounted crystal holder member adapted to be rigidly positioned on the camera track of a standard type of X-ray diffraction apparatus and thereby extend the latter''s inherent ability in taking Laue patterns of small types of crystalline structures to the further capability of taking X-ray diffraction pictures of the relatively large or macro-type crystal.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
119 words
In an X-ray diffraction camera apparatus as in claim 1, wherein said adjustable, indirect, and intermediately positioned arm support comprises a rodlike member releasably and adjustably retained at one end portion thereof in telescopic, mounted relation within the said hollow support member incorporated in one side of said main, crystal specimen-frame support element; and said indirect, plate-holder element comprises an enlarged head portion assembled to the opposite end of said arm support and being further interconnected with a macro-crystal specimen of substantially regular configuration; said head portion being pivotally and adjustably mounted on said rodlike member to enable its independent movement and adjustment relative thereto and thus follow or conform with the contour of the crystal specimen mounted thereon.
Claim 2
Dependent Claim
98 words
In an X-ray diffraction camera apparatus as in claim 1, wherein said adjustable, indirect, and intermediately positioned arm support comprises a clamp device having a main support incorporating one end porTion releasably and adjustably interfitting in an enlarged opening formed in one side of said main, crystal specimen-frame support element, and further projecting outwardly therefrom towards said film-cassette means and film and terminating in a second end portion in close proximity to said film and incorporating a pair of jawlike elements adjustable relative to each other for thereby releasably retaining macro-crystal specimens of different sizes and irregular configurations.
