Technical Examples
  1. A magnetic field generating assembly comprises a superconducting magnet located in a cryostat defining a bore accessible from outside the cryostat, and a mechanical refrigerator having at least two cooling stages for at least partly cooling the cryostat. A coolant path extends from the refrigerator into the magnet bore. The coolant path is coupled for heat exchange with a cooling stage of the refrigerator other than the coldest cooling stage, so that the refrigerator is adapted also to cool coolant in the coolant path.
  2. A refrigerator adapted for use in low ambient temperature conditions such as in an unheated garage or outdoors on a deck or patio. The refrigerator is provided with a low ambient heater to add heat to the refrigerated space when ambient temperatures outside the refrigerator are low enough that items stored in the refrigerator could freeze. The low ambient heater is controlled by an ambient thermostat located to sense temperatures outside the refrigerator. The low ambient heater and ambient thermostat are connected in the refrigerator control so that the ambient heater can not be energized when the cooling system is operating.
  3. This invention provides a superconducting magnet apparatus capable of preventing or restraining the heat invading into the apparatus and reducing the refrigeration load of an external refrigerator, at the time of changeover of a switch in transiting to a persistent current mode, and capable of quick changeover operation. In the superconducting magnet apparatus of the present invention (1), in transiting to a persistent current mode, a thermal superconducting switch (41) placed in a low-temperature domain and a mechanical switch (42) placed in a mid-temperature domain are turned on. Since the mechanical switch (42) is placed in the mid-temperature domain, even if a heat load is generated through the drive mechanism (60), it is not necessary to cool the mechanical switch to an extremely low temperature. In short, heat generated at the contact point of the mechanical switch (42) and heat invasion through the drive mechanism (60) are applied not to the low-temperature domain, but to the mid-temperature domain, so that an external refrigerator can easily absorb the heat load and the capacity of the refrigerator can be reduced.
  4. An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The bottom freezer refrigerator includes an automatic ice maker in an insulated module positioned outside the freezer compartment. The insulated module can be mounted to the exterior of the refrigerator cabinet. An ice cube storage bin can be provided in the insulated compartment or on the inside of the refrigerator compartment door. A passage can connect the insulated module with the ice dispenser on the refrigerator compartment door.
  5. An ice making and dispensing system suitable for making and dispensing ice through the refrigerator compartment door of a bottom freezer refrigerator. The ice maker is positioned in an insulated sub-compartment in the refrigerator compartment maintained at a temperature below 0° C. An insulated ice cube storage bin and ice dispenser are positioned on the refrigerator compartment door for dispensing ice cubes through the face of the refrigerator compartment door.
