Abstract: A storage system useful for storing cryogenic liquids is disclosed. The storage system includes a storage vessel, insulation surrounding the storage vessel and a flexible vacuum jacket enclosing them both. The flexible vacuum jacket can be made from a flexible plastic film such as polyimide. Polyimide is preferred due to its ability to remain flexible at cryogenic temperatures. The inner volume of the flexible vacuum jacket is placed under vacuum such that the insulation is maintained under vacuum. The flexible vacuum jacket can collapse against and conform to the insulation when it is evacuated, saving substantially on volume. A fitting for combining multiple passageways is also disclosed, so that multiple passageways can proceed through the vacuum jacket through a single penetration.

Abstract: A sealing gland for accommodating a ribbon-shaped element is provided to include a fitting, a bore, an alignment assembly and a cap portion. The bore extends along an axis through the fitting. The alignment assembly is configured to be mounted within the bore and includes an element slot such that the ribbon-shaped element can extend through the alignment assembly. The element slot is cuboidal in shape and is defined by a length, a height and a width. The alignment assembly is arranged so that the length is parallel with the axis. The cap portion is configured to be mounted on the fitting to retain the alignment assembly.
