Abstract:
The invention can be used for the pressurised storage of gases. The aim of the invention is to provide a pressurised container consisting of fibre-reinforced plastic with flat or practically flat lids. To achieve this, wound axially aligned reinforcement structures run through the interior of the body and absorb the major part of the required forces on their plane of alignment. The invention is characterised in that fibre strands are distributed uniformly over the cross-sectional surface of the cylindrical pressurised container, are aligned axially and fixed to flat or practically flat lids. In one advantageous embodiment of the invention, a container is formed by the spiral winding of an essentially unidirectional fibre-layer, which is thicker at its edges. Reinforcement layers, which are arranged in a circumferential direction and exert a radial action, cover the reinforcement strands or the spirally wound unidirectional fibre-layer, said layers forming the casing of the pressurised container.
Abstract:
Disclosed is a flat inner container (3), especially an internal tank for a road vehicle, which is surrounded by an outer container (1) and is used for receiving a cryogenic liquid, particularly a fuel. Said inner container (3) is characterized by a combination of the following features: a longitudinally extending monolithic base (4) with a top wall (5) and a bottom wall (6) which are connected to also longitudinally extending sidewalls (7), and with at least two longitudinally extending, substantially straight webs (9) that connect the bottom wall (6) to the top wall (5) so as to form at least one longitudinally extending chamber (10) which is arranged between the webs, extends along the entire length of the base (4) as well as from the bottom wall (6) to the top wall (5), and has a predetermined width between the webs; and at least two caps (11) which tightly seal the two open ends of the base (4) at the periphery; the top wall and/or the bottom wall is/are provided with an arch relative to a planar reference top wall and/or reference bottom wall, the distance of said arch between the inner contour of the top wall and/or the bottom wall and the planar reference top wall and/or reference bottom wall amounting to less than 30 percent of the width of the chamber in the center between the webs.
Abstract:
The invention relates to a container for cryogenic fuel, which has a flat construction and which is surrounded by super insulation. The aim of the invention is to produce a container which can be adapted automatically and in an economical manner to various vehicle models and/or installation situations and can resist mechanical as well as thermal loads. As a result, it is composed of several similar straight and closed profiles (4, 5) which are arranged adjacent to each other in various configurations, said profiles being straight profiles which are arranged in a parallel manner in relation to each other, whereby the at least one external defining wall (14, 15, 16, 17) maintains a functional distance in relation to an external defining wall (18) of an adjacent profile and a common closure is embodied as a common connection chamber of the profile (6, 7) which is closed on the open end thereof (28, 29) on both sides. The reinforcements (24, 25) are, preferably, symmetrical to the sides of the external walls thereof (14, 15, 16, 17) in rectangular profiles.
Abstract:
The invention relates to a cryostat (1) for studying samples in a vacuum. This cryostat comprises a cold finger (2) provided with a finger part (5) as well as with a finger base (10) connected to the finger part. The cryostat also comprises a sample carrier (32) mounted at an end of the finger part that is free from cooling, this finger part being placed in a vacuum enclosure (4). This vacuum enclosure is partially delimited by a hollow part (6) consisting of a single piece and defining an open cavity (46) with a single opening (44) through which the finger part passes. The sample carrier is located inside this open cavity (46). The enclosure is also delimited by a cryostat body (8) whose cylindrical outer surface (36) with a circular cross-section interacts with a device (62) for rotating.
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:
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.

Die Erfindung betrifft einen Druckbehälter zur Speicherung von kryogenem Kraftstoff in einem Kraftfahrzeug, dessen Mantel aus Behälterteilen zusammengesetzt ist, die mindestens in einer zu deren Mittellängsachse parallelen oder schiefen Ebene abgeschnitten und an den Schnittstellen miteinander und mindestens teilweise durch Einlagen in der Schnittebene verbunden sind. Die Erfindung ist dadurch gekennzeichnet, dass die Form der Behälterteile erzeugt wird, indem ein Kreisquerschnitt mit oder ohne Durchmesserveränderung entlang einer Leitkurve gezogen wird und dass die Einlagen gerade und/oder gewölbte Zwischenböden und/oder Rohr- und/oder Profilverbinder sind.
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 polymorphous reservoir structure for a pressurized liquid, comprising at least one outer shell, an enclosure for receiving a pressurized liquid, whereby said structure (2) is provided with one or more means of reinforcement (7,8, 9) and the choice and/or distribution of said means of reinforcement is determined by taking the mechanical characteristics into account in addition to the stress exerted by said pressurized liquid in order to meet at least one given stress state.
