Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
57 words
An X-ray tube having a rotary anode and a focal spot path upon said anode having an outer surface consisting of the same material throughout the focal spot path, said anode and said focal spot path consisting of sectors separated by adjoining surfaces extending through the anode from the center of the anode to its outer edges.
Claim 2
Dependent Claim
57 words
An X-ray tube having a rotary anode and a focal spot path upon said anode having an outer surface consisting of the same material throughout the focal spot path, said anode and said focal spot path consisting of sectors separated by adjoining surfaces extending through the anode from the center of the anode to its outer edges.
Claim 3
Dependent Claim
53 words
An X-ray tube in accordance with claim 1, having a plate-like or ring-shaped anode plate, wherein said separating adjoining surfaces extend radially to divide the anode plate into a plurality of sectors, said sectors having an annular groove upon their bottom surface, and a ring engaging said groove for holding said sectors together.
Claim 4
Dependent Claim
33 words
An X-ray tube in accordance with claim 1, having a cathode and wherein said separating adjoining surfaces extend at least partly in a direction different from that of electrons emanating from the cathode.
Claim 5
Dependent Claim
16 words
