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.
Abstract:
An improved inflammable liquid safety tank comprising a double walled tank body with the tank walls being interconnected by support plates. An intermediate container is formed by the inner wall structure of the tank and is adapted to hold inflammable liquid. A pressurized gas bottle is threadably mounted to a sleeve secured to and extending into the intermediate container. The pressurized gas bottle is selectively connected to the intermediate container to pressurize liquid held in the intermediate container. The pressurized gas bottle also communicates with the tank to pressurize a foam, nonflammable fluid, or cleaning agent placed in the chamber or outer compartment defined by the outer wall structure of the intermediate container and the inner wall structure of the tank body so that the foam, fluid or agent will be expelled from the tank if the tank wall is accidentally punctured. The outer compartment is preferably pressurized at a lower pressure than the intermediate container. A conduit is connected to an inlet/discharge fitting and extends into the intermediate container adjacent the floor of the intermediate container and below the level of liquid placed in the intermediate container. A flexible hose with an adjustable nozzle is mounted to the tank body for selective communication with either the outer compartment or the intermediate container so that the material contained within either of the containers can be selectively discharged from the nozzle.
Abstract:
A substantially rectilinear tank for the storage of cryogenic fluids or the like wherein corrugated baffle plates are oriented with respect to each other and to the sideplates of the tank to provide maximum support both for the pressures built up when the container is in use and the pressures exerted on the structure during fabricating processes.
Abstract:
Tank for use in storing low temperature liquefied gas comprising a rigid outer vessel, a thin film inner vessel with rigid partition walls, and a heat insulating layer inserted between these two vessels. Each of the partition walls extends through the inner vessel and is slidably supported by the outer vessel to permit expansion and contraction of the partition walls. The thin film inner vessel walls are secured to the partition walls at points near where the partition walls pass into the heat insulating layer to form a closed vessel having a large capacity.

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.
