Abstract:
A closure assembly 10 contains positive and/or vacuum pressure within a pressure vessel 16 having a neck 12 . A circumferential locking member 22 supported on a door 20 locks the door to the neck, and is radially moveable between an open position and a closed position. A seal 26 between the neck and the door maintains fluid-tight integrity. A lever or other hand powered operator may be used for moving the locking member between the open position and the closed position. The locking member may include locking segments interconnected to form the circumferential locking member.
Abstract:
La plate-forme structurelle (11) du véhicule comporte deux réservoir (T1) et (T2) pour le stockage sur un véhicule de fluides sous pression. Chaque réservoir comporte au moins un réseau de cellules (2) connectées entre elles via des orifices (3), les orifices étant conformés de façon à ce que le flux de fluide engendré par la consommation de fluide nécessaire à l'utilisation du véhicule ne présente que des pertes de charge n'affectant pas ladite utilisation, et étant conformés de façon à ce que, en cas de rupture d'une ou de quelques cellules (2), le flux de fuite provoque des pertes de charge suffisamment importantes pour en limiter le débit.
Abstract:
A wholly aromatic polyester amide liquid crystal resin including repeating units of:
(I) a 6-hydroxy-2-naphthoic acid residue: 1 to 15 mol %, (II) a 4-hydroxybenzoic acid residue: 40 to 70 mol %, (III) an aromatic diol residue: 5 to 28.5 mol %, (IV) a 4-aminophenol residue: 1 to 20 mol %, and (V) an aromatic dicarboxylic acid residue: 6 to 29.5 mol %, and having a melting point of 270 °C to 370 °C, and having a melt viscosity of 60 Pa·s to 200 Pa·s at a shear rate of 1000/sec at a temperature higher by 10 °C to 20 °C than this melting point is molten at a temperature of the melting point + 40 °C, and extruded at a rate of 0.3 kg/min or more and less than 5 kg/min to form a parison (P). A pair of molds (30) arranged with the parison (P) interposed therebetween are closed under a prescribed mold closing pressure, so that air is blown into the interior of the parison (P).
Abstract:
The present invention relates to a vessel for dispensing and recovering of technical and medical gases and system for delivery and recovery of technical and medical gases.
Abstract:
The invention relates to a method to transfer a cryogenic liquid from a station tank system (1, 2) to a receipient tank (51). At least a part of said cryogenic liquid is stored at a first pressure highter than the pressure in said recipient tank (51) and is cooled to a temperature below the equilibrium temperature for said first pressure. The cooled part of said cryogenic liquid is transferred to said recipient tank (51).
Abstract:
A mounting structure, for a plurality of high pressure gas vessels (11a, 11b), has a block-shaped vessel mounting member (1) with a high rigidity formed with accommodating portions (5a, 5b, 9a, 9b) for accommodating first neck portions (12a, 12b) formed at one sides of the plural high pressure gas vessels and vessel base-valves (13a, 13b) and formed with a gas flow passage (6) that opens at openings (7a, 7b) of right and left side walls of the vessel mounting member (1) to allow the accommodating portions to communicate with one another. The neck portions (12a, 12b) and the vessel base-valves (13a, 13b) at the one sides of the plural high pressure gas vessels are accommodated in the accommodating portions (5a, 5b, 9a, 9b) of the vessel mounting member 1, and the plural high pressure gas vessels are mounted in the vessel mounting member (1), enabling the gas flow passage 6, formed in the vessel mounting member (1), to serve as a high pressure conduit portion.
Abstract:
A hydrogen storage unit which uses hydrogen storage alloys (10) to store hydrogen, and more particularly a heat transfer management/compartmentalization system for use in such a system. The hydrogen storage alloy may be divided into compartments, separated by disks (13), further divided into subcompartments by a flapper wheel. The disks (13) and flapper wheel provide for optimal heat transfer throughout the system. The compartmentalization of the vessel may prevent compaction of the hydrogen storage alloys, which could lead to excessive strain on the vessel causing damage, deformation, or rupture of the vessel.

Abstract:
A device for heating hydrogen storage canister includes a canister containing chamber for accommodation of at least one hydrogen storage canister, a catalyst bed arranged in the canister containing chamber for catalysis. A blowing device provides an air flow through an air flow leading pipe to a nozzle section which is connected with a heating gas drawing pipe to the catalyst bed. A heating fuel storage tank supplies heating fuel which is conveyed to the nozzle section through a heating fuel supplying pipeline, a coiled pipe and a heating fuel conveying pipe in sequence. When the air flow flows through the nozzle section, the heating fuel is drawn into the nozzle section to mix with the air flow, forming a heating gas. The heating gas is atomized by the nozzle section and flows to the catalyst bed where the heating gas is catalyzed to burn to generate a hot gas to heat the hydrogen storage canister.
