Abstract
Abstract In an X-ray goniometer an apparatus comprising a specimen holder, a first motor to move the holder in a linear reciprocating path parallel to the specimen face exposed to the X-rays, a second motor to rotate said holder about an X-axis normal to said face and passing through the center of said specimen, a third motor to rotate said holder about a Y-axis normal to said X-axis and lying in the plane defined by the incident and diffracted X-rays and a fourth motor to rotate said holder about a Z-axis normal to said plane and passing through said specimen; all four motors are adapted to be controlled independently of one another.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
160 words
In an X-ray goniometer for determining the complete polar configuration of the texture of a crystalline specimen by sensing the reflected and transmitted X-rays diffracted by certain crystal lattices of said specimen after impinging on one face thereof, the improvement comprising: A. a first means for imparting a linear reciprocating motion to said specimen parallel to said face thereof; B. a second means for imparting a rotation to said specimen solely about an X-axis normal to said face and through the center of said specimen; C. a third means for imparting a rotation to said specimen solely about a Y-axis normal to said X-axis and contained in a plane defined by the impinging and diffracted X-rays; and D. a fourth means for imparting a rotation of said specimen solely about a Z-axis normal to said plane and lying on said face of said specimen, said first, second, third and fourth means being simultaneously operable individually and independently of one another.
Claim 2
Dependent Claim
160 words
In an X-ray goniometer for determining the complete polar configuration of the texture of a crystalline specimen by sensing the reflected and transmitted X-rays diffracted by certain crystal lattices of said specimen after impinging on one face thereof, the improvement comprising: A. a first means for imparting a linear reciprocating motion to said specimen parallel to said face thereof; B. a second means for imparting a rotation to said specimen solely about an X-axis normal to said face and through the center of said specimen; C. a third means for imparting a rotation to said specimen solely about a Y-axis normal to said X-axis and contained in a plane defined by the impinging and diffracted X-rays; and D. a fourth means for imparting a rotation of said specimen solely about a Z-axis normal to said plane and lying on said face of said specimen, said first, second, third and fourth means being simultaneously operable individually and independently of one another.
Claim 3
Dependent Claim
21 words
The improvement as defined in claim 1, wherein said first, second, third and fourth means each includes an independently controllable motor.
Claim 4
Dependent Claim
54 words
The improvement as defined in claim 2, including a ring surrounding and supporting said specimen, said first and said second means; said ring has a normal axis coinciding with said Y-axis; said ring and said specimen are rotatable as a unit about said Y-axis by virtue of said motor associated with said third means.
Claim 5
Dependent Claim
51 words
The improvement as defined in claim 3, including a circular frame; said Z-axis extends diametrically with respect to said frame and passes through the center thereof; said frame, said ring and said specimen are rotatable as a unit about said Z-axis by virtue of said motor associated with said fourth means.
Claim 6
Dependent Claim
18 words
The improvement as defined in claim 1, including a holder means for fixedly supporting said specimen during operation.
Claim 7
Dependent Claim
29 words
The improvement as defined in claim 5, wherein said holder means includes a frame directly engaging and holding said specimen and a holder receiving said frame with said specimen.
Claim 8
Dependent Claim
25 words
The improvement as defined in claim 6, wherein said holder includes means for selectively supporting said frame in either of two fixed, mutually perpendicular positions.
Claim 9
Dependent Claim
97 words
The improvement as defined in claim 7, wherein said holder includes two parallel spaced inner faces each provided with two pairs of grooves, one pair of grooves is perpendicular to the other pair, the grooves forming a pair are parallel to one another and are provided on one of each inner face, said frame is selectively insertable into one or the other said pair of grooves. 9, The improvement as defined in claim 7, wherein said holder is pivotally supported by a base and means are provided to immobilize said holder in either of said two positions.
