Abstract:
The present invention concerns a light weight composite pressure container for fluids adapted to hold fluids under both high and low pressures, such as H 2 , industrial gases, CNG (compressed natural gas) and LPG (liquefied petroleum gas), as well as a method of manufacturing the same.
Abstract:
Pressure container for fluids, such as propane and butane, comprinsing an inner, fluid-tight liner layer (1) and a pressure supporting layer (2) outside the liner, as well as an outer, protective casing (5). As known per se the said layers (1, 2) consist of transparent or translucent materials, and the casing (5) comprises a middle section (7) having surface portions (7A, 7B, 7C) being cut-away so that parts of the actual container (3), being located inside the casing (5), are visible from the outside, and that the casing has shock-absorbing properties.
Abstract:
An article comprises a containment means supporting pressurized gas-filled microbubbles, the gas being controllably releasable on demand by fracturing the microbubbles. The article of the invention is useful as a fuel or oxidant storage and delivery system to supply electrochemical power devices, such as fuel cells and chemical batteries, particularly those used in portable power applications. Specific applications include a fuel source for a hydrogen/air fuel cell replacement of rechargeable batteries used in portable computers, camcorders and the like, or for powering remote sensing devices.
Abstract:
An apparatus for storage of compressed hydrogen gas is provided. The apparatus includes a sealed housing having an outlet pipe coupled to the housing and equipped with a controllable discharge valve. The sealed housing defines a chamber that includes a cartridge comprising a plurality of cylindrical voids containing said compressed hydrogen gas. The apparatus also includes a hydrogen liberating tool configured for controllable liberating the hydrogen gas from the cartridge into a volume of the chamber that is not occupied by the cartridge. The apparatus is controlled by a control system operatively coupled to the controllable discharge valve and the hydrogen liberating tool, and configured for controlling operation thereof. According to another aspect of the invention, there are provided a system and method for filling the cartridge. The filling includes vacuumizing a chamber into which the cartridge is placed; preparing the cartridge in order to let the hydrogen gas diffuse into the cylindrical voids; and controlled hydrogen gas compressing in the chamber over a predetermined compression time interval until the pressure in the chamber reaches a predetermined pressure value.

Abstract:
A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.
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 a method for manufacturing a pressure container comprising an inner liner layer of polymer material, such as polyolephines or a similar material, and an outer, fibre-reinforced and pressure supporting layer, characterized by treatment of the outer side of the inner liner layer so as to increase the wetting and adhesive properties of the polymer material, employing an adhesive at the outer side of the inner liner layer and/or in direct contact between the outer side of the inner liner layer and the inner side of the outer fibre-reinforced, pressure supporting layer, and winding of the outer, fibre-reinforced and pressure supporting layer onto the inner liner layer. In a preferred embodiment the treatment of the outer side of the inner liner layer comprises flaming, but also corona-discharging, possibly in combination with ozone treatment, or a corresponding method for improving the wetting and adhesive properties of the polymer material can also be employed.
Abstract:
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 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 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 Xe and above 6 hours for He 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.
