Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
126 words
WITH A SUPERCONDUCTING MAGNET COIL, IN COMBINATION, A CRYOSTAT DEVICE FOR COOLING THE COIL TO A TEMPERATURE BELOW THE CRITICAL VALUE BY EVAPORATION OF CRYOGENIC MEDIUM, COMPRISING AN EVACUABLE HOUSING, AN EVACUABLE CONTAINER ENCLOSING SAID MAGNET COIL, SAID CONTAINER BEING INSERTED IN SAID HOUSING AND FORMING THEREWITH AN ANNULAR INTERSPACE, AN EVAPORATOR STRUCTURE MOUNTED IN SAID CONTAINER, AND SURROUNDING SAID MAGNET COIL, SUPPLY MEANS FOR GASEOUS HEAT EXCHANGE MEDIUM CONNECTED WITH SAID CONTAINER FOR FILLING AND REPLENISHING IT WITH SAID HEAT EXCHANGE MEDIUM, A CRYOGENIC CIRCULATION SYSTEM INCLUDING SAID EVAPORATOR STRUCTURE FOR EVAPORATING CRYOGENIC MEDIUM IN SAID EVAPORATOR STRUCTURE TO COOL SAID HEAT EXCHANGE MEDIUM IN SAID CONTAINER, SAID CRYOGENIC MEDIUM IN SAID EVAPORATOR STRUCTURE BEING SEPARATED FROM THE GASEOUS HEAT EXCHANGE MEDIUM IN SAID CONTAINER.
