A tensioned intra-Dewar spider assembly that can support a large system inside the Dewar in a way that adds as little thermal load as possible, doesn't overly stress the coldfinger, maintains alignment, and isolates the components from the vibrations of the cryocooler is disclosed.

A closing element for selectively blocking an opening of a cryogenic storage container is disclosed. The closing element has a head assembly and a bottom member, at least one layer of insulating material disposed between the head assembly and the bottom member, at least one hole extending through the insulating material, and at least one member disposed in the at least one hole and extending through the insulating material. A diameter of the at least one hole is substantially equal to a diameter of the at least one member.

Method, system, apparatus, and/or device for predicting the failure of a shipper. The failure prediction system includes a first sensor configured to detect or measure first sensor data. The failure prediction system includes a memory configured to store a dewar failure model that models a failure of various shippers given one or more constraints. The failure prediction system includes a processor coupled to the memory and the first sensor. The processor is configured to estimate or predict a probability or a likelihood that a shipper will fail before or during a subsequent shipment of the shipper based on the first sensor data and the dewar failure model. The processor is configured to provide the estimated probability or likelihood that the shipper will fail before or during the subsequent shipment of the shipper.

A tube-array-type liquid nitrogen container includes a container body having a mouth; a tube array component received in the container body; and a top cap sealing the mouth from above. The top cap is rotatable in the mouth. The tube array component is composed of a plurality of holding tubes. The holding tube is opened at one end thereof, wherein the opening thereof faces the top cap. The top cap has at least one tube access passing therethrough. Each tube access is atop covered by a tube access cover. The tube-array-type liquid nitrogen container uses a tube-array component composed of the a plurality of holding tubes to store the freezing tubes, and is cooperated with the rotatable top cap and an external robotic arm, thereby improving space utilization and thermal insulation, effectively ensuring safety of the freezing tubes, and facilitating automatic storage of freezing tubes.

A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. A dosing arm has a proximal end and a distal end, with a central passage extending between the proximal and distal ends and configured to receive cryogenic fluid from the doser body. Multiple dosing heads are mounted to the distal end of the dosing arm with each of the dosing heads including a dosing valve. The dosing heads are configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid when the dosing valve is opened.

Method, system, apparatus, and/or device for monitoring a shipment. The vapor plug system includes a vapor plug. The vapor plug fits onto a shipper and partially seals contents within a payload area of a shipper. The vapor plug system includes a sensor that is configured to measure or determine a condition or location of the shipper. The vapor plug system includes an electronic device that has a display. The display is configured to provide the condition or the location to a user. The vapor plug system includes a vapor plug adapter. The vapor plug adapter includes a recessed pocket that is configured to receive the electronic device. The vapor plug adapter includes an opening within the recessed pocket and is configured to receive the sensor and allow the sensor to be inserted into the payload area of the shipper.

A cryogenic fluid containment system is disclosed. The system can store a fluid such as hydrogen at a cryogenic temperature and pressure. As the fluid naturally warms, boil-off fluid is produced by the fluid and can be directed to a backup power system that is configured to consume the boil-off fluid. The boil-off fluid being extracted from the cryogenic fluid containment system causes additional boil-off fluid to be generated from the fluid and refrigerate the fluid within the cryogenic fluid containment system. Additionally, the boil-off fluid can be monitored over time such that as the boil-off fluid accumulates within the storage tank, a boil-off controller can determine whether the boil-off fluid is to be extracted from the storage tank. The boil-off controller can enable the fluid to be maintained below a pressure threshold within the storage tank.

An apparatus includes a Dewar having an endcap. The apparatus also includes a heat sink and a thermal interface material configured to thermally couple the endcap of the Dewar to the heat sink. The thermal interface material includes an amorphous pliable material that is configured to transfer thermal energy between the endcap of the Dewar and the heat sink without structurally coupling the Dewar to the heat sink. A thermal shoe may be positioned between the thermal interface material and the heat sink, and the thermal shoe may be configured to hold the thermal interface material against the endcap. The thermal shoe may have (i) a smaller cross-sectional size in a portion of the thermal shoe contacting the thermal interface material and (ii) a larger cross-sectional size in a portion of the thermal shoe contacting the heat sink.

A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid.

A method for extracting a liquid phase of a cryogen comprising the liquid phase and a vapour phase from an interior volume of a storage dewar through an extraction means, utilizing a push gas introduced into the vapour phase of the cryogen through an outlet of a supply line provided between a push gas supply and the interior volume of the storage dewar, the supply line partially extending through the liquid phase within the interior volume.
