Abstract:
The invention relates to a fibre-reinforced pressure vessel (1, 6) comprising a rigid gas- or fluid-tight body (2, 7, 13, 19) overwound with fibre filaments (3, 10, 11, 18), whereby the fibre filaments are wound such that at least a number of fibre filaments can freely move in respect of one another and when the pressure vessel is under internal pressure the fibre filaments are strained exactly in their longitudinal direction. The invention also relates to a method of manufacturing a fibre-reinforced pressure vessel whereby no matrix material (for example, resin) is used so that at least a number of fibre filaments would be incorporated in a matrix for that section of the pressure vessel in which the fibre filaments can freely move in respect of one another.
Abstract:
A method and an installation for alternating storage of CO2 and natural gas in a way that ensures minimal mixture of the gases, is described. CO2 and natural gas are alternately stored in a tank installation comprising a plurality of tanks connected in series, where CO2 is always filled and emptied through a first tank in the series of tanks, and where natural gas always is filled and emptied through a last tank in the series of tanks.
Abstract:
A fitting (260) with a dual locking swaging mechanism includes a projection to be inserted into the open end of an elastomeric tube (262). A ferrule (280) is connected at one end thereof to a body portion of the fitting and is swaged (286) over the tube to hold the tube onto the projection inserted into the tube. The tube is thereby held to the fitting by both frictional engagement of the tube with the projection and the ferrule and by the connection of the ferrule with the main body of the fitting.

Abstract:
The invention concerns safety tanks, toric or not for motor vehicles with dual-fuel carburation LPG, to be generally located in the spare wheel housing, characterised in that their structure consists of the assembly of two shells completed or not by a central portion, 19 models as per figure 1. They are all fitted with novel single-piece multiple flanges (8 a, b, c and d), oval-shaped and comprising two orifices, one for the operating multiple valve and the other for the pressure control valve as per R 67 standards and capable of being open-air mounted for economising energy and protecting the environment.
Abstract:
Flat, pressure-resistant reservoir (7) of metal, suitable for containing a material under pressure, for example, for the storage of liquid gas to be used as motor fuel, whose opposing walls (1) having the largest area are partly fixedly interconnected by means of hourglass-shaped hollow profiles (2) interposed between these walls, and which reservoir (7) is further provided with supply and discharge means for the material to be contained, the reservoir being made of a metal, the hollow profiles (2) being formed by deep drawing, and the contacting parts (4) of the dished longitudinal halves being interconnected in a leak-proof fashion by welding (8), the form of the generators of the frustoconical profiles and the curved profile of the dished longitudinal halves having the form of a quarter-circle, and owing to the selected distribution pattern of the profiles over the central part of the dished halves, the interior of the reservoir (7) being subdivided into interconnected spherical pockets (10).
Abstract:
A method of manufacturing a high-pressure fluid vessel includes forming a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded to the first portion of the high-pressure fluid vessel.
Abstract:
In order to enlarge a tank volume of a hydrogen powered aircraft, an aircraft tank for storing cryogenic H2 is configured as a non-circular dorsal tank. The aircraft tank may be configured as a conformal fuel tank fitted to an outer contour of an aircraft fuselage. Further, an aircraft is provided with such an aircraft tank.
