Abstract:
An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.
Abstract:
The present invention relates to the field of membrane gas holders, or gasometers, particularly of the type that can be used to store biogas (organic gas) generated through the digestion of sludge, slurry and organic substances in general, or for storing gas emitted from slurry storage tanks containing fermentable matter. More in detail, the invention relates to an elastically stabilized gasometric dome (1) for a tank (2) containing liquid (3), adapted to delimit, between the surface of said liquid (3), the walls (2') of the tank and the dome, a variable volume storage chamber (4) for gas, wherein said gasometric dome (1) comprises: - a gas impermeable flexible membrane (5); - continuous fastening means (6) of an edge (5') of said membrane (5) to a rim (2") of said tank (2). Said membrane (5) is made of an inextensible material, having an extension of the surface thereof greater than that of the surface delimited by the rim (2") of said tank (2), and said gasometric dome (1) comprises a plurality of linear elastic elements (7) arranged orthogonally with respect to the rim (2") of said tank (2), adapted to cooperate with said membrane (5) to allow elastic expansion and contraction of said gasometric dome (1) and ensure the stability thereof.
Abstract:
Die Erfindung betrifft ein Tragluftdach für einen Fermentationsbehälter einer Biogasanlage, welches mindestens zwei auf einem Silagebehälter möglichst gasdicht befestigte vertikal übereinander liegende Folien beinhaltet, von denen mindestens eine als äußere Schutzfolie zum Schutz vor mechanischer Beschädigung mindestens einer gasdichten inneren Biogasfolie dient, wobei in den Innenraum zwischen Schutzfolie und Biogasfolie Tragluft über ein Luftgebläse einführbar ist, welche die Schutzfolie stützt und von der Biogasfolie auf Abstand halten kann und innerhalb des mit Tragluft befüllbaren Innenraumes, zwischen Schutzfolie und Biogasfolie, mindestens ein, bevorzugt eine Vielzahl von Abstandshaltern vorgesehen ist/sind.
Abstract:
The invention relates to a tank for a cryogenic liquid gas, in particular for LNG; that is, for liquid natural gas or liquid methane. The invention further relates to an aircraft having such a tank and to a method for producing such a tank. A tank is produced, which comprises an outer, dimensionally stable structure and a pressure-resistant, cold-resistant film which is able to suitably capture an overpressure resulting from boil-off gas in the tank. The suitably flexible film is coiled so that a hose-shaped chamber or a hose-like sleeve is thus formed. With the aid of the film, a sufficiently pressure-resistant, cold-resistant, light tank for storing cryogenic liquid gas can be provided according to the invention, which can also be subsequently installed in an aircraft primarily due to the flexibility of the film.
Abstract:
A cryogenic tank for use in a vessel. The tank is mounted between two horizontal fundaments (8,9) or decks, where the tank is resting on the lower fundament (9). The top of the tank is connected to the upper fundament (8) by an upper cylindrical skirt (7), and the upper cylindrical skirt (7) has a diameter smaller than the diameter of the cylindrical part of the tank (1). The upper cylindrical skirt (7) rests on the inner part of a horizontal outer part (4) of the top of the tank. The outer part of the top of the tank has a flexibility arranged to absorb changes of the upper and lower fundaments (8, 9) positions according to each other, and at the same time absorb changes of the dimensions of the tank in consequence of temperature changes.
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).
