Abstract:
An impact resistant tank for storing cryogenic fluids, includes an inner metal tank having a metal side wall and a metal bottom and a concrete outer wall around the inner metal wall and having reinforcement therein to resist impact loads thereon, and to serve as a secondary containment for the cryogenic fluid.
Abstract:
Component parts of a steel container for storing a gas, specifically a mixture of stabilized methylacetylene and propadiene (C.sub.3 H.sub.4), are joined by a brazing alloy consisting of about 48% to 67% by weight copper; about 4.5% to about 7% by weight phosphorous and the balance nickel. During manufacture of the container, component parts may be joined either by brazing the joint with the specified alloy in wire or rod form or by applying to the joint a brazing paste comprising the specified metals unalloyed in powdered form and heating the joint in a furnace to melt and alloy the metals to form the joint. The brazing alloy has desirable metallurgical characteristics and is nonreactive to exposure to the specified gas stored in the container. The brazing paste has characteristics which enhance its utility for mass production techniques.

Abstract:
A storage tank having an inner shell, an outer shell surrounding and spaced from the inner shell, a flexible main membrane between the inner shell and the outer shell, granular insulation between the inner shell and the membrane, and tension line means girding the membrane and pressing it into contact with the granular insulation. The tank can be spherical, cylindrical or other shape.
Abstract:
Thermal insulation material is affixed to the outer surface of the inner sidewall of a double walled storage tank but spaced from the outer sidewall to form a gaseous space therebetween and a blackish wall on the radially outer face of said insulating material faces said tank outer sidewall.
Abstract:
A composite construction is provided comprising a load-bearing substrate, an impermeable liner, and disposed therebetween a circulatory system defined by a network of cells having side walls which are generally in lateral orientation to the liner and the load-bearing substrate, at least some of said side walls having apertures therein whereby at least some adjacent cells are in communication with each other. This construction has the capability of being formed with a variety of flow paths through the circulatory system whereby provision may be made for leak detection, inert gas circulation, heat exchange and the like.
Abstract:
A wall construction for fluid handling devices, especially fluid storage tanks, which is adapted for expansion and contraction, has a moistureproof expansion joint which does not materially weaken the wall construction. The expansion joint includes a slit in a portion of the wall and a shaped expansion member of substantially rigid material overlaying the slit. The member is integrally bonded to the wall on opposite sides of the slit and is shaped to allow for movement of the wall. The expansion joint is particularly suited for insulated tanks having a sandwich construction comprising reinforced plastic layers separated by a layer of polyurethane foam. The expansion member is preferably of glass fiber reinforced plastic.
Abstract:
Heat for maintaining operating pressure in a single phase cryogenic fluid at or above the critical pressure is provided by controllably circulating a portion of the warmed delivery fluid in heat exchange with the storage fluid. The circulated delivery fluid is reheated and recombined with the remainder of the delivery fluid. A regulator device having a double acting valve element movable between two opposite positions controls flows respectively to a pressurizing heat exchanger coil and to a bypass leading directly to delivery.
Abstract:
An apparatus is provided for holding fluid material distinguished by being balanced in such a way that when placed on a horizontal surface its position will change depending upon whether the fluid contents exceed or fall below a pre-selected minimum.
Abstract:
A vessel supported by a plurality of rigid members, each of said rigid members being supported at the bottom on a base by at least two pivots, and each of said rigid members being pivotally connected at the top to the vessel at spaced apart locations such as below or about the periphery thereof. The rigid members permit expansion and contraction of the vessel, such as during post-weld heat treatment, internal pressure testing of the vessel, or when the vessel is subjected to a wide temperature cycle during use such as for storage of a cryogenic liquid on land or in a barge or ship.
Abstract:
A structural light-weight panel of high strength, having thermal insulation properties that render the panel particularly suitable for cryogenic and elevated temperature applications. The panel is constituted by a composite core bonded to a carrier membrane or laminated to facing skins, the core including at least one layer formed by a series of balsa beams in spaced relation, the spacing between the beams being filled with slabs of an insulating material such as rigid foam plastic material whose k-factor is similar to that of balsa, whereby the overall thermal insulating characteristics of the composite core are effectively equivalent to that of a homogeneous core composed entirely of foam plastic material, whereas the structural characteristics of the composite core are far superior thereto. The panels are useable as liners for structural enclosures for the storage of fluids at cryogenic to high temperatures.
