Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
In combination, an X-ray tube head assembly comprising a housing with a front surface through which an X-ray beam is emitted; a structural support system anchored at a first location and carrying said tube head assembly at a remote location, said structural support system constituting means whereby the position of said assembly and the orientation of said front surface may be adjusted; mounting structure carried by said housing in non-interfering relation with respect to said front surface; and a removable handle element releasably coupled to said mounting structure; said mounting structure and handle being mutually adapted to couple with and decouple from each other; and said handle constituting means whereby said structural support system may be operated to effect changes in the spatial location of said assembly and the orientation of said front surface.
Claim 2
Dependent Claim
134 words
In combination, an X-ray tube head assembly comprising a housing with a front surface through which an X-ray beam is emitted; a structural support system anchored at a first location and carrying said tube head assembly at a remote location, said structural support system constituting means whereby the position of said assembly and the orientation of said front surface may be adjusted; mounting structure carried by said housing in non-interfering relation with respect to said front surface; and a removable handle element releasably coupled to said mounting structure; said mounting structure and handle being mutually adapted to couple with and decouple from each other; and said handle constituting means whereby said structural support system may be operated to effect changes in the spatial location of said assembly and the orientation of said front surface.
Claim 3
Dependent Claim
61 words
A combination according to claim 1 wherein said mounting structure comprises a post element extending from said housing, said post element constituting first coupling means; and said removable handle has a grip section and a coupling section, said coupling section constituting second coupling means; said first and second coupling means being mutually adapted for coupling with and decoupling from each other.
Claim 4
Dependent Claim
41 words
A combination according to claim 2, wherein said removable handle includes a guard section at the end of said grip section closest said post element; said guard section being configured to isolate a hand clasping said grip section from said housing.
Claim 5
Dependent Claim
37 words
A combination according to claim 2, wherein said first coupling means carries first screw threads and said second coupling means carries second screw threads, said first and said second screw threads together forming a male/female threaded coupling.
Claim 6
Dependent Claim
49 words
A combination according to claim 4, wherein said first coupling means comprises male threads at the distal end of said post element; and said second coupling means comprises female threads in a well carried by the proximal end of said handle element opposite said grip section from said guard.
Claim 7
Dependent Claim
47 words
A combination according to claim 4, wherein said handle element includes an approximately prismatic body member including said grip section at its distal end and said second coupling means at its proximal end and said guard comprises an approximately cylindrical disk flange member circumscribing said body member.
Claim 8
Dependent Claim
17 words
A combination according to claim 6, wherein said body member is shaped approximately as a truncated cone.
Claim 9
Dependent Claim
27 words
A combination according to claim 6, wherein said flange member is annular with a central aperture adjusted to releasably engage the outer surface of said body member.
