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.

Abstract:
The invention relates to a pressure vessel (10) for gases, in particular helium, which is characterized in that the pressure vessel has an outer casing having pressure resistance up to an internal gas pressure of at least 10 bar, in that the outer casing of the pressure vessel has at least one highly diffusion-resistant barrier layer having a leak rate for helium at an internal gas pressure of 10 bar and room temperature of preferably less than 10−2 mbar·l/s, and in that the vessel has an accommodating volume for gas at atmospheric pressure of at least 25 liters. The outer casing of the pressure vessel can comprise at least one barrier layer made of a flexible polymer film having a high barrier function or ultra barrier function or at least one highly gas-tight flexible barrier layer made of EVOH. The vessel can be bag-like or, in particular at higher pressures, inherently rigid. High-strength plastics made of fiber granular materials, for example, can be used to produce the layer, which guarantees the high pressure resistance. Seams (12) can be provided, for example in the lateral edge areas, in order to reinforce and stabilize the pressure vessel. The pressure vessel (10) according to the invention can have a ball valve (11) as a closing element in order to remove the gas.
