Abstract:
The present invention relates to a metal nozzle boss provided with a sealing device, which has highly improved tightness and is combined with a plastic liner of a composite vessel used as a high-pressure vessel. The metal nozzle boss uses an elastic seal ring and a tightening piece in the plastic liner, so that the nozzle boss reliably seals the junction of the nozzle boss and the liner and prevents gas leakage from the vessel. The blade part of the nozzle boss has a dovetail-shaped locking groove, with locking ridges formed in the locking groove. Thus, when the plastic liner is produced by injecting molten resin into the locking groove, the plastic liner is securely combined with the metal nozzle boss. The composite vessel having the metal nozzle boss can be used as a fuel tank for natural gas vehicles or a hydrogen tank for fuel cell vehicles.
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure tank and an internal defect detecting method in a pressure tank, capable of surely and quickly detecting, such internal defects as cracks and the like in the liner, after improving the maintenance efficiency by reducing man-hours and cost for maintenance, while continuously using a vehicle. SOLUTION: In a fuel gas tank 9, the outer surface of liner 23 is reinforced with a reinforcing layer 24 constituted of fiber reinforced plastics and is provided with an ultrasonic sensor 37, connected to the liner 23, which detects the radio transmitting through the liner 23 and a diagnosis circuit 38, connected with the ultrasonic sensor 37, determining whether a crack C exists in the liner 23, based on the detection results of the ultrasonic sensor 37. The diagnosis circuit 38 determines generation of the crack C of the liner 23 with the radio detected by the ultrasonic sensor 37, when hydrogen gas is to be filled inside the liner 23, and outputs an abnormality signal, when the crack C of the liner 23 generates.

Abstract:
Fluid storage and dispensing systems, and processes for supplying fluids for use thereof. Various arrangements of fluid storage and dispensing systems are described, involving permutations of the physical sorbent-containing fluid storage and dispensing vessels and internal regulator-equipped fluid storage and dispensing vessels. The systems and processes are applicable to a wide variety of end-use applications, including storage and dispensing of hazardous fluids with enhanced safety. In a specific end-use application, reagent gas is dispensed to a semiconductor manufacturing facility from a large-scale, fixedly positioned fluid storage and dispensing vessel containing physical sorbent holding gas at subatmospheric pressure, with such vessel being refillable from a safe gas source of refill gas, as disclosed herein.

Date Oct. 14, 1993.An assembly comprising an intermediate volume of medium-pressure gas (8) in a transportable housing (3) which is advantageously combined with a user apparatus (4) and selectively connectable to a high-pressure gas supply (1) by coupling it to a filling unit (2) via a quick connection system (15, 16). The assembly is particularly useful in portable welding apparatuses.
Abstract:
Apparatus for storing a combustible gas including a pressure storage vessel, a pressure relief valve communicating with the storage vessel for venting the gas from the vessel when the pressure therein is too high, and a catalytic reactor communicating with the pressure relief valve to catalytically combust the gas exiting the valve and thereby reduce the amount of such gas that enters the environment.
