A sealed and thermally insulating tank for storing a fluid, the tank being anchored in a load-bearing structure, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the tank having a support foot that is fastened to the load-bearing structure in a zone of a bottom wall of the tank, the support foot being arranged to guide a vertical translational movement of the loading/unloading tower, the tank having at least one sump that is formed in the bottom wall of the tank, the bottom wall of the tank having a corrugated sealing membrane that is intended to be in contact with the fluid having at least first corrugations extending in a first direction and spaced apart from one another, the sump and the support foot are spaced apart by a distance at least three first corrugations pass between the sump and the support foot.

A propane tank seat accessory device provides an upper seating surface to support a user seated thereon on a portable propane tank with a cylindrical body and a protective cage surrounding a valve at the top end thereof. The device has a seat with a lower supporting surface for being supported on an upper edge of the protective cage and which defines the upper seating surface thereon. A sleeve extends downwardly from the lower supporting surface having an exterior diameter receivable within the protective cage of the propane tank in which a bottom end of the sleeve can be engaged upon the top end of the tank body. The sleeve has a valve opening therein for communication of the valve structure therethrough.

A valve comprising a first chamber (111) and a second chamber (112), wherein a movable member (204) is arranged to selectably bring the first and second chambers into and out of fluid communication with one another, the movable member arranged such that when in an open position wherein the first and second chambers are in fluid communication, gas at a first pressure in the first chamber provides a closing force to a first surface area (222) of the movable member to overcome an opening force provided by gas at a second pressure in the second chamber on a second surface area (223) of the movable member whereby the movable member moves to a closed position to isolate the first and second chambers, and further arranged wherein as the movable member moves to the closed position, the second surface area of the movable member exposed within the second chamber is reduced thus reducing the opening force provided by the gas at the second pressure and providing a bias towards the closed position.

A high-pressure tank comprises a liner, a strengthening layer including a first helical layer and a first hoop layer each including a carbon fiber, and a protective layer including a second helical layer and a second hoop layer each including a glass fiber, in this order. The high-pressure tank is provided with a stress-generating portion, a reinforcement layer includes a first area α overlapping the stress-generating portion in a stacking direction and a second area β that is an area except for the first area, and a one-round portion including a final crossing portion at an end of winding of the glass fiber constituting the second hoop layer overlaps the second area in the stacking direction.

A gas supplying apparatus includes a compressor, a housing having an exhaust port, and an exhaust duct. The housing has a circumferential wall and a top wall. The circumferential wall has an access section. The exhaust port is provided on at least one of the circumferential wall and the top wall at a location higher than the access section. The exhaust duct includes a discharge port for discharging the air, exhausted from the exhaust port, to the outside. The discharge port is opened upward or opened downward in an area overlapping the top wall in an up-and-down direction.

Disclosed herein is an attachment system, for providing a component mounting location, that comprises a laminated structure and a bracket. The bracket comprises an interface surface configured to interface with a first side of the structure, and a through hole open at the interface surface. A shear stud of the attachment system comprises a projection, shaped to pass through the hole of the structure and engage the through hole of the bracket, and a seal region, positioned to interface with a second side of the structure to form a seal with the second side of the structure. The attachment system additionally comprises a fastener comprising a head and a shaft, the shaft being shaped to pass through the through hole in the bracket and engage the shear stud to secure the shear stud relative to the bracket thereby reducing shear at the fastener.

A pressure vessel mounting structure (10) includes a plurality of bands (11) made of a composite material cured about the exterior surface (35) of the pressure vessel (30) to form an integral part of the vessel. The bands (11) may be spaced apart from one another to form a crisscrossing helical grid pattern with opposing ends (21) of the bands extending past a respective end (31) of the pressure vessel (30) and toward a longitudinal centerline (33) of the pressure vessel (30) to form a skirt (17). The skirt (17) provides mounting points (15) as well as a vertical standing mount for the vessel.

A design and construction method for a Collapsible Cryogenic Storage Vessel can be used for storing cryogenic liquids. The vessel provides the ability to be packed for transport in a compact state and erected at the point of use. The vessel can be used multiple times. The vessel's volume can also be adjusted during use to minimize or eliminate head space in the vessel.

A restraining structure for a structural body includes: a restrained portion that is a tubular body or a stacked body; a pair of holding portions provided at the restrained portion; a first CFRP belt wrapped around the restrained portion in an axial direction of the restrained portion so as to extend between the pair of holding portions and having carbon fibers of a 0° direction along the axial direction; and a second CFRP belt stacked adjacent to an outermost layer near an end of the first CFRP belt and having carbon fibers of 45° to 90° directions with respect to the axial direction. One of the holding portions is provided at an end of the restrained portion. The other of the holding portions is provided at the other end of the restrained portion.

The invention provides a device for protecting a high-pressure gas tank of a motor vehicle. The device includes at least one heat-conducting plate and a thermal triggering unit. The heat-conducting plate has a distal region and a proximal region. The proximal region is arranged immediately adjacent to the thermal triggering unit and the distal region is arranged at a distance from the thermal triggering unit. The heat-conducting plate may be shaped so that it tapers from the distal region to the proximal region. The proximal region itself may be shaped in a tapering fashion. The heat-conducting plate may include heat-conducting fibers.
