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.

An apparatus for analyzing the content of at least one contaminant in a liquid cryogen comprising a cylindrical enclosure, an annular enclosure arranged around the cylindrical enclosure, means for dividing a flow of liquid cryogen in two, means for delivering a first part of the liquid cryogen to the cylindrical enclosure, means for delivering a second part of the liquid cryogen to the annular enclosure, a pipe connected to the cylindrical enclosure to allow vaporized liquid to pass through, a pipe connected to the annular enclosure to allow vaporized liquid to pass through, a heater for heating the cylindrical enclosure vessel and means for stopping the delivery of liquid cryogen to the cylindrical enclosure.

A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.

A cryogenic pressure container for a motor vehicle has an inner container and an outer container. An evacuated space is arranged between the inner container and the outer container at least in some regions. The inner container has a synthetic material layer. A barrier layer is arranged at least in some regions between the synthetic material layer and the evacuated space. The barrier layer is designed and arranged so as to at least reduce the transfer of constituents leaking out of the synthetic material layer into the evacuated space, wherein a gap is formed at least in some regions between the barrier layer and the synthetic material layer.

A low vibration cryostat includes a cryocooler with a cold head having a flange and a cooling body extending from the flange. A housing is coupled to the cold head, with the housing having an opening receiving at least a portion of the cooling body. A first bellows extends between the housing and the flange to mitigate the transfer of vibrational forces between the housing and the flange. The first bellows, the flange, and the housing collectively define a first chamber. A force balancing assembly containing a second bellows is coupled to the housing and includes a second chamber spaced from the first chamber. The two chambers are arranged to create a net zero force on the cold head when the pressure in the bellows changes. A viscous damping assembly mitigates bouncing of the cold head on support springs.

Methods, apparatus, and device, for a cryogenic storage system that stores and/or transports a liquid or gas at a temperature below ambient temperature. The cryogenic storage system has an enclosure and a cavity. The cryogenic storage system has a dewar that is positioned within the cavity of the enclosure. The dewar has a payload area that is configured to hold a liquid below ambient temperature. The dewar is configured to hold a liquid below ambient temperature and passively stabilize in an upright position. The dewar is formed with an inner wall and an outer wall and has an opening that allows access to the payload area.

A dewar vessel storage apparatus configured to hold at least two dewar vessels containing liquefied gas or cryo-compressed gas, comprising; a box having an outer, thermally insulating, wall; the box comprising a plurality of insulating cavities, each cavity configured to receive a single dewar vessel and is thermally insulated from each other cavity; a thermally insulating closure arrangement configured to close an open end of each cavity; a ventilation assembly comprising at least one conduit within the box configured to provide for venting of gas released from the dewar vessels when stored in the respective cavities of the box, the ventilation assembly configured to provide a gas outlet flow path from each cavity.

Disclosed herein is an attachment system, for providing a component mounting location, that comprises a laminated structure and a bracket. The bracket comprises an interface surface configured to interface with a first side of the structure, and a through hole open at the interface surface. A shear stud of the attachment system comprises a projection, shaped to pass through the hole of the structure and engage the through hole of the bracket, and a seal region, positioned to interface with a second side of the structure to form a seal with the second side of the structure. The attachment system additionally comprises a fastener comprising a head and a shaft, the shaft being shaped to pass through the through hole in the bracket and engage the shear stud to secure the shear stud relative to the bracket thereby reducing shear at the fastener.
