Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
77 words
For the transmission of X-rays in medical X-ray examination and therapy devices, the use of carbon fiber tissue embedded in epoxy synthetic resin matrices for the patients table top, for the side of the casing of the X-ray image-intensifier directed toward the source of the X-rays, for the side of the casing of the X-ray spotfilm device directed toward the source of the X-rays and for the sides of cassettes directed toward the source of the X-rays.
Claim 2
Dependent Claim
77 words
For the transmission of X-rays in medical X-ray examination and therapy devices, the use of carbon fiber tissue embedded in epoxy synthetic resin matrices for the patients table top, for the side of the casing of the X-ray image-intensifier directed toward the source of the X-rays, for the side of the casing of the X-ray spotfilm device directed toward the source of the X-rays and for the sides of cassettes directed toward the source of the X-rays.
Claim 3
Dependent Claim
19 words
An X-ray device according to claim 1 having a patient's table top manufactured by epoxy resins strengthened with carbon-fibers.
Claim 4
Dependent Claim
33 words
An X-ray device according to claim 2 having a patient's table top with a plate manufactured of epoxy resins strengthened with carbon-fibers, said plate being stretched between longitudinal bars of said table top.
Claim 5
Dependent Claim
