Abstract:
The present invention concerns a pressure container (1) with a jacket comprising partial cylindrical jacket shells (2, 4) that are located parallel next to each other and define a bead (8, 10) in the longitudinal direction. The end faces thereof are closed off by a curved bottom (16, 18), wherein between the partial cylindrical shells (2, 4) a tractive element designed in particular as a flat wall (6; 6a, 6b) is arranged, the upper or lower edge (12, 14) of which extends into or penetrates the upper or lower bead region (8, 10). There is furthermore provided a shell element (42) running in the longitudinal direction and connecting the jacket shells (2, 4) and the tractive element (6), being firmly connected at least in sections to the jacket shells (2, 4) and to the particularly beveled edge (12, 12a; 14, 14a) of the tractive element (6), so that a girder structure is formed in the bead region (8, 10). The invention further relates to a transport container arrangement, particularly a tank container unit (100) having a pressure container (1) according to the invention.
Abstract:
A pressure vessel for holding a pressurized fluid such as compressed natural gas (“CNG”) includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.
Abstract:
A tank for cryogenic liquids, which is intended for installation in motor vehicles and which consists of an outer container and of an inner container suspended in the latter in tension or compression struts. In order to take the contrasting requirements in motor vehicles into account in an optimum way, between the outer container and inner container abutments and supporting faces are additionally provided, which can be spaced apart from one another when the vehicle is at a standstill and can be brought to bear when the vehicle is driving. The abutments inside the outer container Co.-operate with supporting faces on the inner container and can be displaced by means of an actuator.

Abstract:
A reinforced composite structure (29) is disclosed. The structure is formed by opposed layers of material extending over a core and continuous bundles stitched in a repeating pattern through the opposed layers (30, 32) and the intermediate core (28) to form the reinforced composite structural member (29).
Abstract:
A tank for compressed natural gas utilizes internal tension members. The tank has an upper half and a lower half, each half being formed with at least two cylindrical portions separated by a Y-shaped junction. The sections of each half have engagement members in the interiors. The engagement members include a head and a socket which slide longitudinally together to secure the upper and lower halves against tension due to the gas pressure.
Abstract:
The invention provides cryogenic structures, e.g. vessels or tanks joined by longerons, which are made of durable plastic composite materials rather than of metal, which vessels can contain cryogenic materials including fuel, without need of a liner or other weighty layers of the prior art. The structures are made of, e.g. a fiber network impregnated with a matrix of thermoset plastics, thermoplastics or a combination thereof. Thus the invention includes a cryogenic vessel of, e.g. 3 tank lobes, made of a composite of plastic reinforced with fibers, which lobes are joined together and supported by woven, cruciform shaped longerons which are also impregnated with plastic, to define a composite support member.
Abstract:
A container for pressurized fluid has a generally rectangular outer shell with relatively flat partitions across the width thereof forming a plurality of compartments. The opposite inner surfaces of each compartment along the length of the vessel are cylindrical. End closures are sealed around the outer shell and they are dished to leave a space around the partitions to enable flow between the compartments.
Abstract:
The tank is a modified form of the lobed tank described in British Pat. No. 1522609, whereby the tank ends are of simpler constructional form. Thus, the tank comprises, top, bottom and two opposed side walls (1 to 4) each consisting of parallel, part-cylindrical lobes (11) which are connected and tied together by tie-plates (13, 14) and elongated armed insert elements (16, 17 and 17a). The invention is characterized in that each one of said other two opposed side walls (5, 6) comprises at least two part-lobes (11c) which present straight edges to which the common straight end edges of a series of two-way corner transition (12c) and part-transition (12d) pieces are joined, and in that the end of each part-lobe (11c) has a respective part-transition piece (12d) joined thereto to present a curved edge to which a part-spherical three-way corner (12b) can be joined to close-off the side wall (5 or 6). Preferably, the transition and part-transition pieces are joined together via elongate curved insert elements (12e) in which there is a smooth transition from being of generally "Y" cross-section at one end to "T" cross-section at the other end.

1,050,954. Carrying liquefied gases. LINDE A.G. Feb. 17, 1964 [Feb. 15, 1963], No. 6486/64. Heading B7A. [Also in Division F4] A substantially rectangular or trapezoidal storage container for liquefied gases has walls formed from a plurality of outwardly curved sections and the intersections of the curved sections on two opposite side walls are provided with external supports which bear against fixed walls whereas the intersections on the other two opposite side walls are connected by internal ties or partitions. The rectangular container, Figs. 1 and 2 (not shown), is supported externally by the walls 27 of a ship and is formed from four vertical part-cylindrical edge sections connected on two opposite sides by upper and lower part cylindrical horizontal edge sections 2, 3, and at the other sides by similar horizontal edge sections 2a. The edge sections are filled in by welded part-cylindrical sections or by rectangular plates 21 which are outwardly bowed in two directions. The external walls may be of single or double walled construction. The sections are preferably joined together by welding adjacent edges to junction pieces which extend inwardly where they are either welded to the partition walls or ties 22, and outwardly where they support the container by means of pivoting supports 24 which allow the container to move vertically or horizontally, and hinged horizontal pivots 23 which allow only vertical movement of the container. The vertical edge plates are provided with upper and lower cylindrical extensions closed by covers 16 and bases 17. Alternatively the outer corners of the container may be formed at the top and bottom by hollow part spherical components 4 fabricated by welding together triangular subsections cut from a part cylindrical plate. In the generally trapezoidal container of Figs. 3 and 4 (not shown) the curved sections 35, 36, 37 thereof are hollow part-conical plates the intersections of which are provided with support plates 44 reinforced by transverse ribs 47. The plates 44 carry brackets 46 which coact with plain bearing surfaces 51 secured to the fixed wall of a ship which thereby allow relative horizontal and vertical movement therebetween. The middle support plate 44 along each opposite side wall coacts with a plain bearing surface 49 having lateral guide surfaces 50 which allow only vertical movement of the container. The part-conical corners 35, 36 are reinforced by internal vertical chordal plates 39, 39 1 and internal horizontal apertured plates 41. Horizontal plates 40 are provided for reinforcing the side walls 37.
