Abstract
Abstract The ends of a tapered glass capillary are secured in relatively movable mounting blocks for application of axial tension to the capillary. This mounting enables the capillary to be pulled taut so that its axis is straight to facilitate propagation of X-rays. The capillary is coated to provide flexibility and strength. The ends of the capillary extend into their respective mounting blocks, with at least a portion of each end being stripped of the coating material. A bonding material contacts the glass and the coating material and secures both to their corresponding mounting blocks to hold the capillary in place when tension is applied and to provide shear strength for the capillary wall.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
Apparatus for guiding X-rays, comprising: a glass capillary having an outer surface and a tapered, elongated bore having a relatively large first end and a relatively small second end, the bore being defined by a thin glass wall; cladding means on at least a part of the outer surface of said capillary for strengthening the glass wall thereof; support means for at least one end of said capillary, said support means including mounting means and adhesive means fastening said mounting means to said outer surface of said capillary and to said cladding means; and means for applying tension to said capillary.
Claim 2
Dependent Claim
101 words
Apparatus for guiding X-rays, comprising: a glass capillary having an outer surface and a tapered, elongated bore having a relatively large first end and a relatively small second end, the bore being defined by a thin glass wall; cladding means on at least a part of the outer surface of said capillary for strengthening the glass wall thereof; support means for at least one end of said capillary, said support means including mounting means and adhesive means fastening said mounting means to said outer surface of said capillary and to said cladding means; and means for applying tension to said capillary.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1, said apparatus further including means introducing helium into said capillary bore.
Claim 4
Dependent Claim
67 words
The apparatus of claim 1, wherein said support means includes a mounting block for each end of said capillary, and adhesive means securing a first mounting block to a first end of said capillary and a second mounting block to a second end of said capillary, said adhesive means connecting each block to the outer surface of the capillary and to the cladding at corresponding ends thereof.
Claim 5
Dependent Claim
29 words
The apparatus of claim 3, wherein said support means includes means for moving one of said mounting blocks with respect to the other for applying tension to said capillary.
Claim 6
Dependent Claim
50 words
The apparatus of claim 4, wherein each said mounting block includes means for receiving a corresponding end portion of said capillary, for receiving at least an end portion of said cladding means, and for receiving said adhesive means for securing said capillary and said cladding means to said mounting block.
Claim 7
Dependent Claim
13 words
The apparatus of claim 5, further including gimbal means for said mounting blocks.
Claim 8
Dependent Claim
26 words
The apparatus of claim 5, further including means securing said mounting blocks for relative motion to apply tension to said capillary along a longitudinal axis thereof.
Claim 9
Dependent Claim
24 words
The apparatus of claim 7, further including adjustable means for aligning the end portions of said capillary with the longitudinal axis of the capillary.
Claim 10
Dependent Claim
16 words
The apparatus of claim 8, wherein said adjustable means comprises gimbal means for said mounting blocks.
Claim 11
Dependent Claim
31 words
The apparatus of claim 5, wherein each said mounting block includes an aperture for receiving a corresponding end portion of said capillary, the ends of said capillary extending through said apertures.
Claim 12
Dependent Claim
36 words
The apparatus of claim 10, wherein said cladding means is a plastic coating on said capillary, said coating extending substantially the entire length of said capillary and extending into, but not completely through, the corresponding apertures.
Claim 13
Dependent Claim
26 words
The apparatus of claim 11, wherein said adhesive means is located within said apertures to engage the end portions of said capillary and said cladding means.
Claim 14
Dependent Claim
19 words
The apparatus of claim 12, wherein said mounting blocks are adjustable to align the end portions of said capillary.
Claim 15
Dependent Claim
13 words
The apparatus of claim 13, further including gimbal means for said mounting blocks.
Claim 16
Dependent Claim
25 words
The apparatus of claim 14, further including means for introducing helium into said capillary bore under pressure to produce a slow flow of helium therethrough.
