Abstract:
A hydropneumatic filament-wound pressure vessel is disclosed. The vessel has first and second cup-shaped tank liners having circular open mouths which are provided with a seal and diaphragm assembly. The seal assembly includes a pocket formed by an inner wall and shelf associated with the first liner and a ledge associated with the second liner. The shelf, ledge and cylindrical wall cooperate with an inner surface of the second liner to provide an O-ring pocket. An O-ring is provided in the pocket and the O-ring defines the periphery of a flexible diaphragm which divides the interior of the liners into separate pressure chambers. A continuous filament is wound over the surface of the liners in an isotensoid pattern. Each liner has a geodesic dome surface extending between a diameter of the liner and a polar opening. The dome surface is defined by oppositely curving surfaces of revolution of a meridia joined by an inflection point. The first surface of revolution curves from the liner diameter to a first point just unto but not at said inflection point. The second surface of revolution curves from the polar opening to a second point just unto but not at said inflection point in a direction opposite the curvature of the first surface of revolution. The first and second surfaces are joined, and the inflection point is traversed by a straight line third surface of revolution closely approximating geodesic curvature through the inflection point.
Abstract:
L'invention concerne un procédé pour remplir des conditionnements de gaz comprimé, ainsi que les conditionnements eux-mêmes, lesquels comportent une enveloppe (1) renfermant un agent de pression, et au moins une poche souple (2) située à l'intérieur et servant à recevoir le produit de remplissage. L'espace intérieur de la poche souple (2) est obturé au moyen d'une vanne (6) disposée dans la région de la bouche (4) de l'enveloppe (1). Pour perfectionner encore le procédé précité ainsi que les conditionnements de gaz comprimé s'y rapportant, afin de pouvoir utiliser non seulement n'importe quel agent de pression, notamment de l'air mais également des emballages en fûts métalliques du commerce, et que la totalité du processus de remplissage s'effectue avec une durée relativement plus courte et ainsi à moindres frais, il est proposé dans l'invention de placer la poche souple (2) dans l'enveloppe (1) de manière à laisser entre le bord d'ouverture (3) de la poche (2) et la bouche (4) de l'enveloppe (1) un intervalle (5) pour introduire l'agent de pression. Le bord d'ouverture (3) de la poche (2) conjointement avec la vanne (6) est relié hermétiquement avec la bouche (4) de l'enveloppe (1). Pour réaliser le vide dans l'espace intérieur de la poche (2), on actionne la vanne (6) et après avoir actionné à nouveau cette dernière, on introduit dans la poche (2) le produit de remplissage sous pression. Pour réaliser le vide dans l'espace intérieur de la poche (2), on y applique un vide. La poche souple (2) se présente sous forme de soufflet dont les plis rentrent vers l'intérieur.
Abstract:
The present invention provides a Type 3 pressure vessel comprising a polar boss that is attached to a metallic liner and provides reinforced static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance of the liner orifice or neck region. In particular, the material of the polar boss has higher static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance relative to that of the liner material.
Abstract:
A method and an apparatus for facilitating purging a vessel (1) by means of an inflatable bladder (3), the bladder (3) being connected to a conduit (53, 55, 57) for communicating a fluid into or out of the bladder (3), wherein the method comprising : - arranging the bladder (3) in a compartment (5) outside the vessel (1), the compartment (5) being provided with a closable sealing means (7) adapted for selectively bringing the compartment (5) in fluid communication with the internal of the vessel (1) via an aperture (9) in a portion of the vessel (1); - bringing at least a portion of the bladder (3) into the vessel (1); - inflating the bladder (3) by means of a fluid provided from a fluid source; - cleaning the vessel (1) by purging a space which is defined by an internal surface of the vessel (1) and an external surface of the inflated bladder (3); - deflating the bladder (3); and - bringing the bladder (3) out of the vessel (1) and into the compartment (5).

Abstract:
Gasspeicher mit zumindest einer einen Gasspeicherraum (30) abschließenden, flexiblen Speichermembran (10, 10') sowie einem Gasbefüll- und ― entnahmeanschluss (5), über den Gas in den Gasspeicherraum (30) einleitbar und aus diesem ableitbar ist, wobei ein transportierbarer Container (14) vorgesehen ist, dessen Innenraum die zumindest eine Speichermembran (10, 10') so aufnimmt, dass die zumindest eine Speichermembran (10) sich je nach Füllstand des Gasspeicherraumes heben und senken kann, und dass eine Einrichtung zur Erzeugung eines Stützgasdruckes (1, 3, 3') vorgesehen ist, mit welcher die zumindest eine Speichermembran (10) an ihrer Außenseite mit einem Stützgasdruck beaufschlagbar ist.
Abstract:
Disclosed is a gas accumulator comprising an outer and an inner diaphragm (1, 2). The inner diaphragm (2) partly surrounds a variable gas accumulator chamber (20). A diaphragm opening (40) for a device for measuring the fill level (41) of the gas accumulator chamber is provided within the outer diaphragm (1). Said device encompasses a level sensor (42) that is attached to a sensor holder (59) which is connected to the edge of the diaphragm opening (40) by means of a connecting element (56'). The connecting element (56') is formed by a tube (46), an end opening of which is connected to the edge of the diaphragm opening (40). The sensor holder (59) comprising the level sensor (42) is mounted on the other end opening of the tube (46) such that the tube (46) is fastened over the diaphragm opening (40) and the level sensor (42) is thus placed at a distance from the diaphragm opening (40) by using the supporting pressure prevailing between the inner diaphragm (2) and the outer diaphragm (1).
