  • Differential pressure filling system and method for a dosing vessel
    Patent number: 11585489
    Abstract: A dosing vessel includes a reservoir having an inlet and an outlet and is configured to contain a supply of a cryogenic liquid with a headspace above. The outlet is configured to be connected to a dosing arm having a dosing head. A low pressure sensor is configured to detect a vapor pressure in the headspace. A high pressure sensor is configured to detect a pressure in a bottom portion of the reservoir. An inlet valve is in fluid communication with the inlet of the reservoir and is placed in communication with a source of cryogenic liquid.

  • Interchangeable dosing arm device, system and method
    Patent number: 10451221
    Abstract: A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. The dosing arm has a proximal end and a distal end and a central passage extending between the proximal and distal ends. Furthermore, the dosing arm is configured to receive cryogenic fluid from the doser body. A bayonet connection removably connects the proximal end of the dosing arm to the doser body. A dosing head is mounted to the distal end of the dosing arm and is configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid.
