  • Magnetic resonance imaging cryocooler positioning mechanism
    Patent number: 6144274
    Abstract: An insertion and positioning mechanism to assist in inserting the cryocooler into the sealed cavity of a recondensing superconducting magnet during superconducting operation utilizing guide assembly and slider assembly combinations to resist forces of cryocooler interaction with the magnetic field of the superconducting magnet to avoid misalignment, and to ensure good thermal contact at the cryocooler thermal interfaces.

  • Method and apparatus for precooling a mass prior to immersion in a cryogenic liquid
    Patent number: 5960636
    Abstract: An apparatus and method for precooling a mass to be cooled to a final low temperature by immersion in a cryogenic liquid, e.g. liquefied helium. The gaseous phase of the cryogenic liquid is cooled by heat exchange with a cryogenic liquid having a higher boiling point than the cryogenic liquid within which the mass is to be immersed. The cooled gaseous phase is circulated through a vessel containing the mass, recovered, recooled and recirculated until the mass and its containment vessel are at the desired precooling temperature. Thereafter cryogenic liquid can be introduced into the vessel to immerse the mass.
