Claim 3

The juncture member recited in claim 1 wherein said curved plate has substantIally 90* of curvature between its edges of least curvature and connects the bottom and side liner plates of a cylindrical cryogenic container.

Claim 4

The juncture member recited in claim 1 formed from two curved plates positioned adjacent to one another, each plate having a side extending inwardly from the concave surface thereof, the edges of said sides being welded to one another to form the said elongated corrugation.

Claim 5

In a cryogenic container, including a vertically extending cylindrical, sealed, outer vessel, having a side, a bottom and a top, an insulating layer on the inside surfaces of said side and bottom and a flexible, thin-walled, metal liner located inwardly of said insulating layer consisting of a flat bottom plate and a cylindrical side plate, said cylindrical side plate being supported from above by vertically movable means affixed to its upper edge, a juncture member for connecting said bottom plate to said side plate comprising: a plurality of inwardly concave curved panels attached at their adjacent sides to one another and attached to said bottom plate and said cylindrical side plate at the inner edge and the upper edge thereof respectively, thereby forming a continuous liquid tight bottom corner of said liner, each of said panels describing a 90* curve between said edges and having an elongated corrugation extending radially of said container and projecting inwardly from the concave surface thereof, said corrugation itself having multiple corrugations therein, the principal axes of which are essentially perpendicular to the concave surface of each of said curved panels.

Claim 6

In a cryogenic container, including a vertically extending cylindrical, sealed, outer vessel, having a side, a bottom and a top, an insulating layer on the inside surfaces of said side and bottom and a flexible, thin-walled, metal liner located inwardly of said insulating layer consisting of a flat bottom plate and a cylindrical side plate, said cylindrical side plate being supported from above by vertically movable means affixed to its upper edge, a juncture member for connecting said bottom plate to said side plate comprising: a plurality of inwardly concave curved panels attached at their adjacent sides to one another and attached to said bottom plate and said cylindrical side plate at the inner edge and the upper edge thereof respectively, thereby forming a continuous liquid tight bottom corner of said liner, each of said panels describing a 90* curve between said edges and having an elongated corrugation extending radially of said container and projecting inwardly from the concave surface thereof, said corrugation itself having multiple corrugations therein, the principal axes of which are essentially perpendicular to the concave surface of each of said curved panels.

Claim 7

A juncture member as recited in claim 4 wherein each curved panel has two side flanges extending inwardly from the concave surface thereof, said flanges being parallel to and welded at their edges to the edges of the flanges of adjacent panels to form the said elongated corrugation.

Claim 8

A juncture member as recited in claim 4 wherein each panel is welded to the two panels adjacent to it along the side edges thereof.

Claim 9

In a cryogenic container including a vertically extending cylindrical, sealed, outer vessel, having a side, a bottom and a top, an insulating layer on the inside surfaces of said side and bottom and a flexible, thin-walled, metal liner located inwardly of said insulating layer consisting of a flat bottom plate, an inwardly concave cylindrical side plate and a curved juncture member connecting said side and bottom plates, the improved liner wherein said cylindrical side plate and said curved juncture member are provided with a plurality of elongated inwardly projecting corrugations, extending vertically in said side plate and essentially radially of said cylindrical container in said juncture member, the corrugations in said juncture member each having multiple corrugations therein, the principal axes of which are essentially perpendicular to the surface of said juncture member.

Claim 10

In a cryogenic container including a vertically extending cylindrical, sealed, outer vessel, having a side, a bottom and a top, an insulating layer on the inside surfaces of said side and bottom and a flexible, thin-walled, metal liner located inwardly of said insulating layer consisting of a flat bottom plate, an inwardly concave cylindrical side plate and a curved juncture member connecting said side and bottom plates, the improved liner wherein said cylindrical side plate and said curved juncture member are provided with a plurality of elongated inwardly projecting corrugations, extending vertically in said side plate and essentially radially of said cylindrical container in said juncture member, the corrugations in said juncture member each having multiple corrugations therein, the principal axes of which are essentially perpendicular to the surface of said juncture member.

Claim 11

The improved liner of claim 7 wherein said side plate and juncture member are formed from a plurality of panels, each having a said corrugation therein, said panels being joined to one another at their side edges.

Claim 12

The improved liner of claim 7 wherein said side plate and juncture member are formed from a plurality of panels, each having two sides flanges extending inwardly from the concave surface thereof, said flanges being welded at their edges to the edges of the flanges of adjacent panels to form the said elongated corrugation.
