摘要:
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.
摘要:
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, fiber-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 fiber-reinforced, pressure supporting layer, and winding of the outer, fiber-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.
摘要:
A compact portable transport unit 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 includes a magnetic holding field which is generated from a solenoid in the transport unit. The solenoid includes a plurality of coil segments and is sized and configured to receive the gas chamber of a container. The gas container is configured with a valve, a spherical body, and an extending capillary stem between the valve and the body. The gas container or hyperpolarized product container can also be formed as a resilient bag. The distribution method includes positioning a multi-bolus container within the transport unit 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 to yet another site.
摘要:
An article comprises a containment means comprising 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 to replace rechargeable batteries used in portable computers, camcorders and the like, or for powering remote sensing devices.
摘要:
Structures, such as pressure vessels or pipes, for the storage and transportation of fluids under pressure are wrapped with a composite material including a high-strength unidirectional filament material in a matrix of a flexibilized isophthalic polyester resin which has an elongation at least equal to the elongation of the material of the structure. The index of refraction of the resin is matched to the index of refraction of the filament material so that the pressure vessel is visible through the wrapping. The resin discolors when exposed to a heat above which the material of the structure weakens, thus acting as an indicator that the structure is unsuitable for use.
