Abstract:
Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.
Abstract:
The present invention concerns a system for storing energy in the form of compressed air, characterized in that it is made up of a set of straight or wound steel tubes (1) assembled to form a storage volume arranged at the surface, or in a subsurface, the assembly being enclosed in a thermally insulating envelope (2).
Abstract:
A storage system, including an outer casing having an evacuated inner volume; a vessel for storage located within the outer casing and having a plurality of protrusions distributed on an outer surface thereof; and a plurality of filamentary strands spanning the inner volume, wherein at least some of the plurality of protrusions are essentially tangentially contacted by a plurality of the filamentary strands to secure the vessel in six degrees of freedom relative to the outer casing.
Abstract:
In accordance with an aspect of the present disclosure, a conformable high pressure gas fuel storage system has a high pressure gaseous storage vessel with a central section disposed between end sections and in fluid communication therewith. The end and central sections have hollow geometric objects. The geometric objects have self-similarity providing the gas storage vessel with a fractal geometry. Each geometric object of each end section branches into a plurality of the geometric objects of the central section. The geometric objects of the central section have a smaller cross-section and thinner outer wall than the geometric objects of the end sections. The geometric objects of at least the central section are formable with bends to a configuration to conform the gas storage vessel to a space in a vehicle in which the gas storage vessel is packaged.
Abstract:
Provided are an LNG storage container with an inner shell, which is capable of efficiently storing LNG or pressurized LNG (PLNG) pressurized at a predetermined pressure and supplying the LNG or PLNG to a consumption place, and capable of reducing manufacturing costs by minimizing the use of a metal having excellent low temperature characteristic, and a method for manufacturing the same. The LNG storage container includes: an inner shell configured to store LNG inside; an outer shell configured to enclose the outside of the inner shell such that a space is formed between the inner shell and the outer shell; a support installed in the space between the inner shell and the outer shell to support the inner shell and the outer shell; and a heat insulation layer part installed in the space between the inner shell and the outer shell and configured to reduce a heat transfer.
Abstract:
There are provided scalable video encoders and decoders and corresponding methods for scalable video encoding and decoding. A scalable video encoder includes an encoder for selectively using spatial intra prediction to code, on a macroblock adaptive basis, an enhancement layer residue generated between an enhancement layer macroblock and a corresponding upsampled base layer macroblock.
Abstract:
A fixed and/or stationary modular unit consists of a hydraulic fluid tank, a pressurization pump, and a compressed gas transportation system consisting of a cylinder or set of cylinders. Each cylinder has two ends, a charging end and a dispensing end, with actuated valves positioned at each end. A pair of valves are located at each charging end of each cylinder, with one valve connected to an incoming hydraulic fluid line and the other valve connected to a hydraulic fluid return line. A valve is connected at the dispensing end of each cylinder. Adapters at each end of the cylinder have curved J-tubes that extend into the cylinder. The J-tube on the charging end curves downward and the J-tube on the dispensing end curves upward. The cylinder or sets of cylinders are inclined to a desired level for the dispensing process.
Abstract:
An apparatus includes a low-carbon steel member. The low-carbon steel member yields plastically more than about 5% before fracturing at temperatures down to about −40° C. when stress is applied to the low-carbon steel member sufficient to cause the low-carbon steel member to so yield.
