Abstract:
The main opposite surfaces (4a, 4b; 5a, 5b) of the inner (1) and outer (2) coverings are directly linked to each other by rigid coaxial linking elements (9;10), flexible linking elements (15) joining a main surface (5a) of the outer covering to an opposite surface (4b) of the inner covering (1) and vice-versa. The invention can be used for the storage of cryogenic fuel used as a power source for motor vehicles.
Abstract:
Substantially rectangular-shaped tanks are provided for storing liquefied gas, which tanks are especially adapted for use on land or in combination with bottom-supported offshore structure such as gravity-based structures (GBS). A tank according to this invention is capable of storing fluids at substantially atmospheric pressure and has a plate cover adapted to contain fluids and to transfer local loads caused by contact of said plate cover with said contained fluids to a grillage of stiffeners and stringers, which in turn is adapted to transfer the local loads to an internal truss frame structure. Methods of constructing these tanks are also provided.
Abstract:
Portable cooling systems, employing a high pressure reservoir adapted to ergonomically interface with a user and/or a wearable article to deliver a flow of cooling gas through a conduit system are provided. Such a system is adapted to provide powered cooling to locations where only very small and portable cooling systems can fit. Various user retainable appliances or articles may have cooling features incorporated therein. The molded plastic high pressure reservoir may have other uses as well.
Abstract:
A sealed, thermally insulated tank consists of tank walls fixed to the load-bearing structure of a ship, the tank walls having, in succession, in the direction of the thickness from the inside to the outside of the tank, a primary sealing barrier, a primary insulating barrier, a secondary sealing barrier and a secondary insulating barrier, at least one of the insulating barriers consisting essentially of juxtaposed non-conducting elements (3), each non-conducting element including a thermal insulation liner, at least one panel and load-bearing partitions rising through the thickness of the thermal insulation liner in order to take up the compression forces. These partitions include at least one anti-buckle partition (14) that includes a plurality of anti-buckle wall elements that have a respective orientation forming an angle relative to a general longitudinal direction of the anti-buckle partition, for example forming corrugations or double-wall portions.
Abstract:
A vessel for containing a fluid under pressure comprises essentially flat parallel surfaces connected by hemispherical edge closures. Internal tension members are connected between the parallel surfaces to distribute the pressure of the fluid in the vessel. The shape of the vessel can be generally square, triangular, toroidal, or other variation to conform to an available space. The skin of the vessel, the hemispheric edge closures, and the internal tension members are typically fabricated from a high strength lightweight material, such as titanium.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
Abstract:
Methods and systems for transportation of a cryogenic fluid. The system includes a floating liquefaction unit receiving a gas from a source, a shuttle vessel for carrying liquefied gas away from the liquefaction unit, and a floating regasification unit for receiving the liquefied gas from the vessel, regassifying the liquefied gas and providing the gas to a distribution system.
Abstract:
The tank for fluid under pressure comprises one or an assembled-together plurality of individual containers or modules made at least in part out of composite material. The or each individual container (20) comprises a cylindrical body (22) of composite material, two end plates (30) closing the axial ends of the cylindrical body, and at least one belt passing around the container substantially in a longitudinal direction and bearing against portions of the outside faces of the end plates.

Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The vessel may be formed in a variety of useful shapes and the tubes may have various internal and external cross-sections. The end caps may be filled with sintactic foam with canals leading to the passageway. Microtubes through the syntactic foam may connect the tubes to the passageway. The vessel is further strengthened by overwrapping with high-strength braiding material, hoop winding or by overlayment with high-strength fabric. The vessel is further strengthened by coating with plastic resin. Apparatus and methods for forming the cellular reservoir flexible vessels are described.
