Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
A pressure support unit for limiting strain in a superconducting magnet coil induced by the magnetic field generated by the magnet coil comprising: a restraining member surrounding said superconducting magnet coil for withstanding the force of the magnetic field generated by said superconducting magnet coil; a pressure compartment disposed between said superconducting magnet coil and said restraining member and having a least one segment for receiving fluid pressurized proportional to the intensity of the field generated by said superconducting magnet coil for counterbalancing the force produced by the magnetic field and communicating a portion of the stress and resultant strain to said restraining member and reducing the strain in the said superconducting magnet coil.
Claim 2
Dependent Claim
114 words
