Abstract:
A transport unit includes a plurality of permanent magnets arranged to provide a magnetic holding field for protecting hyperpolarized gas during storage and/or transport. The permanent magnets are configured in a relatively light weight manner to project a substantially cylindrical magnetic holding field or spherical holding field in space. The magnet arrangements can include primary magnets and field shaping secondary magnets which act to enlarge the region of homogeneity. The permanent magnet arrangement can also be provided with a cylindrical shaped flex sheet magnetically activated to provide the magnetic holding field. The permanent magnet arrangements do not require disassembly to insert or remove one or more containers of hyperpolarized gas in or out of the transport unit.
Abstract:
The present invention relates to the field of membrane gas holders, or gasometers, particularly of the type that can be used to store biogas (organic gas) generated through the digestion of sludge, slurry and organic substances in general, or for storing gas emitted from slurry storage tanks containing fermentable matter. More in detail, the invention relates to an elastically stabilized gasometric dome (1) for a tank (2) containing liquid (3), adapted to delimit, between the surface of said liquid (3), the walls (2') of the tank and the dome, a variable volume storage chamber (4) for gas, wherein said gasometric dome (1) comprises: - a gas impermeable flexible membrane (5); - continuous fastening means (6) of an edge (5') of said membrane (5) to a rim (2") of said tank (2). Said membrane (5) is made of an inextensible material, having an extension of the surface thereof greater than that of the surface delimited by the rim (2") of said tank (2), and said gasometric dome (1) comprises a plurality of linear elastic elements (7) arranged orthogonally with respect to the rim (2") of said tank (2), adapted to cooperate with said membrane (5) to allow elastic expansion and contraction of said gasometric dome (1) and ensure the stability thereof.

Abstract:
A resilient multi-layer container (10) is configured to receive a quantity of hyperpolarized gas and includes a wall with at least two layers (41,44), a first layer with a surface which minimizes contact-induced spin-relaxation and second layer which, e.g., is substantially impermeable to oxygen. The container is especially suitable for collecting and transporting 3 He. The resilient container can be formed of material layers which are concurrently responsive to pressure such as polymers, deuterated polymers, or metallic films. The container can include a capillary stem (26s) and/or a port or valve isolation means (31i) to inhibit the flow of gas from the main volume of the container during transport. The resilient container can be configured to directly deliver the hyperpolarized noble gas to a target interface by deflating or collapsing the inflated resilient container.
Abstract:
A system and method utilising compressed gas according to which the gas is compressed at a location (10) above ground and transported to an underwater location(16). The gas is stored at the underwater location and later returned from the underwater location to the above-ground location for utilisation as energy.
Abstract:
A compact portable transport unit (10) for shipping hyperpolarized noble gases and shielding same from electromagnetic interference and/or external magnetic fields includes a means for shifting the resonance frequency of the hyperpolarized gas outside the bandwidth of typical frequencies associated with prevalent time-dependent fields produced by electrical sources. Preferably the transport unit (10) includes a magnetic holding field which is generated from a solenoid (20) in the transport unit. The solenoid (20) includes a plurality of coil segments (21, 22, 23) and is sized and configured to receive the gas chamber of a container (30). The gas container (30) is configured with a valve, a spherical body, and an extending capillary stem (35) between the valve and the body. The gas container or hyperpolarized product container (30) can also be formed as a resilient bag (30b). The distribution method includes positioning a multi-bolus container (30) within the transport unit (10) to shield it and transporting same to a second site remote from the first site and subsequently dispensing into smaller patient sized formulations which can be transported (shielded) in another transport unit (10) to yet another site.
