    摘要： A resilient multi-layer container is configured to receive a quantity of hyperpolarized noble fluid such as gas and includes a wall with at least two layers, a first layer with a surface which minimizes contact-induced spin-relaxation and a first or second layer which is substantially impermeable to oxygen. The container is especially suitable for collecting and transporting 3He. 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 and/or a port or valve isolation means 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. In addition, single layer resilient containers with T1's of above 4 hours for 129Xe and above 6 hours for 3He include materials with selected relaxivity values. In addition, a bag with a port fitting or valve member and one or more of a capillary stem and port isolation means is configured to minimize the depolarizing effect of the container valve or fitting(s). Also disclosed is a method for determining the gas solubility in an unknown polymer or liquid using the measured relaxation time of a hyperpolarized gas.

    摘要： A support for an air tank of the type used in breathing apparatus has an improved means for releasably gripping the tank. It uses, for this purpose, crank elements rotatable with parallel bars to which are secured arms that clamp the tank between them. The crank elements overlap in a space between the bars, and their overlapping areas are slidably and pivotally interengaged. Swinging movement of one of the elements produces corresponding swinging movement of the other to rotate the bars between opposite extreme positions in one of which the clamp arms grip, and in the other release, the tank or cylinder. A user releases the cylinder by throw of a conveniently disposed handle. The handle rotates a cam in contact with a cam follower in the form of an angular arm rigid with one of the crank elements, to translate rotation of the cam through approximately 90.degree. into a swinging movement of the articulated linkage defined by the crank elements, over a dead center. The clamp arm support bars are in this way jointly rotated in opposite directions to swing the clamp arms outwardly. The cylinder is thus released. The throw of the handle in the opposite direction produces a reverse movement of all of the parts, causing clamping engagement of the supported cylinder.

    摘要： A tubular wall is axially telescoped over an end closure and a wall outer end portion is secured to the end closure so that complete separation between the wall and end closure will not take place up to internal reservoir pressures spaced above a predetermined pressure, but at the same time, such securement permitting fluid flow outwardly between the wall and end closure at reservoir pressures at least as low as the predetermined pressure. A wall inner end portion is formed in an annular zone arcuately inwardly against a resilient sealing ring positioned in an end closure arcuate recess compressing the sealing ring against the end closure. By selecting the physical characteristics of the wall and sealing ring, the compressive force of the wall against the sealing ring retains reservoir pressure up to the predetermined pressure and automatically at least temporarily deforms to permit fluid flow by the sealing ring and outwardly between the wall and end closure above the predetermined pressure thereby providing automatic safety relief of any attempted pressures above the predetermined pressure. The securement of the wall outer end portion with the closure member may be by formation of the wall over an annular shoulder of the closure member depending on inherent rigidity of the wall for securement or formation of the wall along an outer end surface of the closure member with pressure clamping by a clamping ring.
