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.

The invention is related to a storage vessel (1) comprising a shaped body (3) of a porous solid, wherein the storage vessel (1) comprises a wall (5) with a section (7) comprising at least one inlet (9), wherein the storage vessel (1) has a central axis (11) and the central axis (11) is a longitudinal axis of the storage vessel (1) and/or perpendicular to a cross-sectional area of the at least one inlet (9), wherein the shaped body (3) covers at least 85% of an inner volume (13) of the storage vessel (1) and the shaped body (3) comprises an opening (19) in an axial direction (17), axial referring to the central axis (11) of the storage vessel (1), wherein the opening (19) extends from a first end (21) of the shaped body (3) to an opposing second end (23) of the shaped body (3) and wherein the storage vessel (1) comprises exactly one shaped body (3), which is formed in one piece. The invention is further related to a shaped body and use of the shaped body.

This invention relates to a safety valve for a pressurised gas cylinder, the valve comprising: (a) a housing comprising a proximal end and a distal end, the housing comprising a conduit which extends through the housing from an inlet at the proximal end to one or more outlets at the distal end, the inlet being connectable to a gas cylinder so that it is capable of providing fluid communication between the conduit and the gas cylinder; (b) a closure member within the conduit which is movable from a closed position in which it substantially seals the inlet to an open position which provides fluid communication through the conduit from the inlet to the one or more outlets at the distal end of the housing; and (c) a thermal release element within the conduit in the form of a fluid-filled glass bulb comprising a first end which abuts a stop on the housing and an opposing second end which abuts a distal side of the closure member in order to hold the closure member in the closed position.

A cryogenic vessel includes an outer vessel at least partially formed from a reinforced concrete. The cryogenic vessel further includes an inner vessel disposed in the outer vessel. The cryogenic vessel further includes an airtight liner disposed between the inner vessel and the outer vessel, wherein the liner is anchored to the outer vessel. The cryogenic vessel further includes a vacuum space disposed between the inner vessel and the liner, wherein an insulation material is disposed in the vacuum space.

A pressure vessel has a first end with a first boss, the first boss having a first outer surface. The vessel includes a liner having a second outer surface, a shell disposed over the second outer surface, and a first vent. The first vent is formed onto at least a portion of the first outer surface and at least a portion of the second outer surface. The first vent includes a texture that provides a higher rate of gas flow through the first vent than through a portion of an interface of the liner and shell lacking the texture. In another aspect, a pressure vessel has a first end and a second end, a plurality of first longitudinal vents and a plurality of second longitudinal vents. At least one of first longitudinal vents is circumferentially offset around the pressure vessel from at least one of the second longitudinal vents.
