    Abstract: PROBLEM TO BE SOLVED: To provide a cryogenic dewar bottle having the selectable substantially uniform storage temperature.
    SOLUTION: This invention has an inside tank 44 surrounded by an outside shell 42, and is characterized by vacuously insulating a space 46 between these. For example, a pressure vessel 60 including a cryogenic liquid coolant such as liquid nitrogen, is at least partially arranged inside the dewar bottle 40 for cooling a coolant. The pressure vessel 60 is pressurized so that the temperature of a cryogenic liquid can be controlled. A cooler and a temperature or pressure sensor communicate with the cryogenic liquid in the pressure vessel 60. When the sensor detects that the temperature of the cryogenic liquid is warmed by exceeding a predetermined level, the cooler is automatically operated for cooling the cryogenic liquid in the pressure vessel 60.

    Abstract: A cryogenic fluid delivery system includes a tank (22) adapted to contain a supply of cryogenic liquid (26), with the tank (22) including a head space (36) adapted to contain a vapor above the cryogenic liquid (26) stored in the tank (22). A liquid withdrawal line (28) is adapted to communicate with cryogenic liquid (26) stored in the tank (22). A vaporizer (32) has an inlet that is in communication with the liquid withdrawal line (28) and an outlet that is in communication with a vapor line. A pressure building circuit (55) is in communication with the vapor delivery line and the head space (36) of the tank. The pressure building circuit (55) includes a flow inducing device (52) and a control system for activating the flow inducing device (52) when a pressure within the head space (36) of the tank drops below a predetermined minimum pressure and/or when other conditions exist.

    Abstract: A system for dispensing cryogenic liquid to a use device tank from a bulk storage tank containing a supply of cryogenic liquid features a pump in communication with the bulk storage tank, a dispensing line in communication with the pump and a heater in communication with the dispensing line. A system control device controls the operation of the pump and heater. A liquid level sensor and temperature or pressure sensor communicate with the use device tank and the system control device and the system control device. As a result, the conditions of the cryogenic liquid initially in the use device tank may be used by the system control device to calculate the appropriate amount of cryogenic liquid and heat that should be added to the cryogenic liquid as it is dispensed so that the use device tank becomes substantially filled with saturated cryogenic liquid. A liquid level sensor may alternatively be used as the sole use device tank sensor.

    Abstract: A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increase.
