Abstract
Abstract Insulation for fluid storage chambers includes a hollow vacuumtight tube or sets of tubes surrounding the chamber and spaced from the chamber and from each other by thermal insulating spacer means, each tube, or set of tubes, being in contact with a heatconductive layer extending circumferentially with or without helical windings and spaced convolutions, around the chamber, and separated from one another and from the chamber by thermal insulating spacer means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
An insulated container comprising: a vacuum-tight inner enclosure; a vacuum-tight outer enclosure; a thermally conductive hollow tube extending axially of said container between said inner and outer enclosures; said tube being in contact with an associated layer of thermally conductive material extending circumferentially about said inner enclosure; circumferentially extending spacing means of thermal insulating material radially separating said layer of thermally conductive material from said inner enclosure; and whereby fluid flowing in said hollow tube tends to establish a substantially stable equilibrium temperature for said conductive layer by absorbing and removing heat leakage via conduction through said conductive layer and tube.
Claim 2
Dependent Claim
101 words
An insulated container comprising: a vacuum-tight inner enclosure; a vacuum-tight outer enclosure; a thermally conductive hollow tube extending axially of said container between said inner and outer enclosures; said tube being in contact with an associated layer of thermally conductive material extending circumferentially about said inner enclosure; circumferentially extending spacing means of thermal insulating material radially separating said layer of thermally conductive material from said inner enclosure; and whereby fluid flowing in said hollow tube tends to establish a substantially stable equilibrium temperature for said conductive layer by absorbing and removing heat leakage via conduction through said conductive layer and tube.
Claim 3
Dependent Claim
50 words
A container as claimed in claim 1 having a plurality of said hollow tubes, each tube being in contact with an associated layer of thermally conductive material contacting that tube and each such tube and associated layer being separated from other tubes and their associated layers by thermal insulating material.
Claim 4
Dependent Claim
77 words
An insulated container for cryogenic fluids having: a central enclosure; an outer enclosure; a series of circumferentially extending layers of thermally conductive material extending around said central enclosure; spacing means between said thermally conductive layers for holding said layers in radially spaced relation; and at least one hollow tube of thermally conductive material extending axially of said central enclosure in contact with one of said layers of thermally conductive material but radially spaced from said central enclosure.
Claim 5
Dependent Claim
77 words
An insulated container for cryogenic fluids having: a central enclosure; an outer enclosure; a series of circumferentially extending layers of thermally conductive material extending around said central enclosure; spacing means between said thermally conductive layers for holding said layers in radially spaced relation; and at least one hollow tube of thermally conductive material extending axially of said central enclosure in contact with one of said layers of thermally conductive material but radially spaced from said central enclosure.
Claim 6
Dependent Claim
40 words
A container as claimed in claim 3 wherein there are at least three of said hollow tubes and more of said tubes contact the outermost conductive layer than contact any other layer of conductive material inside of said outermost layer.
Claim 7
Dependent Claim
39 words
A container as claimed in claim 3 wherein there are a plurality of said hollow tubes and the number of said tubes contacting successive circumferentially extending layers increases in number progressively from the innermost layer to the outermost layer.
Claim 8
Dependent Claim
21 words
A container as claimed in claim 3 wherein at least some of said spacer means are constituted of thermal insulating material.
Claim 9
Dependent Claim
17 words
A container as claimed in claim 3 wherein the innermost spacer means is a spirally wound ribbon.
Claim 10
Dependent Claim
83 words
Semiflexible cryogenic transfer tubing comprising: inner and outer corrugated coaxial vacuum-tight tubes and successively overlying layers of the following materials in the following sequence between said inner and outer tubes; helically wound spacer means having spaced convolutions; a helically wound hollow heat conductive tube; a heat conductive film in heat conductive contact with said helically wound tube; helically wound spacer means having spaced convolutions layed with a pitch opposite to that of said first named spacer means; and a layer of fibrous insulation.
Claim 11
Dependent Claim
83 words

Claim 12
Dependent Claim
21 words
