The apparatus further includes a bottom passage interconnecting bottom portions of the first and second compartments for fluid communication therebetween.
Abstract:
A lightweight, ergonomically beneficial, hydrodynamic, and volumetrically efficient hybrid pressure vessel having at least two longitudinally extending, semi-cylindrical sections with flattened rib portions at a common interface between the sections. Additional longitudinally extending sections may be employed to provide additional internal volume. One or more apertures extend through the ribs to provide communication between sections. The pressure vessel comprises a cast metal material, optionally including exterior reinforcing structure for containing internal pressure
Abstract:
A method of manufacturing a tank suitable for storing very cold cryogenic liquids, such as liquefied ethylene (LEG) or natural gas (LNG) or a corresponding medium, the basic form of the tank corresponding to a rectangular prism and being manufactured from aluminium or the like material. The tank is produced at least mainly from prefabricated construction elements of few different types so that plane elements to be used as shell panels of the tank, the elements being produced by mechanically extruding aluminium profile elements or the like, are produced, the elements including a plane part and a stiffening part and which are welded by their plane parts to each other using friction welding. The plane elements produced thus are provided with longitudinal and/or transverse stiffeners being produced by mechanically extruding aluminium profile elements or the like, which are welded to each other by using friction welding. The plane elements having stiffeners produced thus are attached to each other and/or to separately produced edge and/or corner elements into self-supporting volume units having at least four sides.
Abstract:
The present invention relates to a multi-cell tank (2) for pressurized gas formed by a group of tubes (2a) immersed in a fibrous resin body (4) and reinforced by means of external texture (7), closed with two covers that feature a intercommunicating series of domes on the internal side, which exactly match the opening of the tubes of the group.
Abstract:
Portable cooling systems, employing a high pressure reservoir adapted to ergonomically interface with a user and/or a wearable article to deliver a flow of cooling gas through a conduit system are provided. Such a system is adapted to provide powered cooling to locations where only very small and portable cooling systems can fit. Various user retainable appliances or articles may have cooling features incorporated therein. The molded plastic high pressure reservoir may have other uses as well.
Abstract:
The storage tank for cryogenic liquids incorporates an ullage vessel that provides for an ullage space. The ullage vessel is in communication through an ullage line to a fill line that provides cryogen to a cryogen space. The junction where the ullage line and fill line meet is of a certain cross-sectional area. Downstream of the junction within the fill line, measured in reference to the direction of cryogen flow during a coruse of filling the cryogen space, is of a greater cross-sectional area than is the case at the junction. This creates a pressure reduction at the junction during a course of filling that causes a net flow of material from the ullage space over the course of filling. Once the cryogen tank is liquid full causing cryogen to be redirected down the ullage line, the smaller cross-sectional area of the ullage line compared to the fill line causes a reduction in flow of cryogen which is detected by the fill pump causing filling to stop providing the ullage space. A means of draining the ullage vessel prior to and during filling of the storage tank is provided.
Abstract:
The tank for fluid under pressure comprises one or an assembled-together plurality of individual containers or modules made at least in part out of composite material. The or each individual container (20) comprises a cylindrical body (22) of composite material, two end plates (30) closing the axial ends of the cylindrical body, and at least one belt passing around the container substantially in a longitudinal direction and bearing against portions of the outside faces of the end plates.
Abstract:
Closure modules are coupled to and enclose ends of a multi-cell pressure vessel, especially a multi-cell pressure vessel having arcuate outer wall segments connected by internal web segments that define a plurality of cells in the pressure vessel. The closure modules each have an arcuate surface portion and at least one interfacing surface portion integrally connected at a marginal extent thereof with a marginal extent of the arcuate surface portion. The arcuate surface and interfacing surface portions define a closure module chamber and have peripheral edges. The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.
Abstract:
A cryostat arrangement for keeping liquid helium comprising an outer shell (2), a helium container (6) installed therein and a neck pipe (4) extending from the helium container to the outer shell whose upper warm end is connected to the outer shell and whose lower cold end is connected to the helium container, wherein the outer shell, the helium container and the neck pipe define an evacuated space (13) containing a radiation shield (15) surrounding the helium container and being connected at a coupling to the neck pipe in a heat-conducting fashion, wherein a refrigerator is installed in the neck pipe having a cold finger (5a) which consists of at least one pipe and projects into the neck pipe, is characterized in that at least one pipe of the cold finger is surrounded by at least one separating body (3a) which divides the neck pipe into two partial volumes (8a and 9a) which are connected to one another through a lower opening (10a) and an upper opening (7a). A cryostat arrangement of this type with active cooling through refrigerators shows considerable improvements over conventional cryostats with respect to thermal properties. In particular, it is possible to completely stop consumption of liquid helium.
