Abstract
Abstract A thermally insulated storage or transport vessel for low-boiling point liquefied gases comprises a rigid self-supporting inner receptacle or tank and a nonself-supporting outer container. The outer container, formed from a pair of longitudinally spaced opposing rigid end shells interconnected by an intermediate shell provided with stiffening formations extending peripherally of the intermediate shell. The intermediate shell is longitudinally expansible or contractile and may be formed with angular-section or curved-section corrugations.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
177 words
An insulated vessel for the storage or transport of liquefied gas comprising: an inner axially elongated generally cylindrical receptacle receiving said liquefied gas; an outer axially elongated generally cylindrical receptacle spacedly surrounding said inner receptacle and defining an evacuatable space therewith, said outer receptacle comprising at its ends a pair of opposing shell members and an intermediate member sealingly connected to said shell members and disposed between the shell members, said intermediate member being formed unitarily with stiffening formations preventing radial expansion and contraction but permitting elastic axial expansion and contraction; and support elements engaging said shell members and supporting said outer receptacle on said inner receptacle, said shell members being formed as dome cylinder bottoms and said intermediate member being a cylindrical wall, said formations extending circumferentially on said wall, said wall being corrugated with the corrugations having crests and troughs lying in planes perpendicular to the axis of said outer receptacle, said inner receptacle having cylinder bottoms at opposite ends thereof, said support elements being rigidly connected to said cylinder bottoms of said inner receptacle.
Claim 2
Dependent Claim
177 words
An insulated vessel for the storage or transport of liquefied gas comprising: an inner axially elongated generally cylindrical receptacle receiving said liquefied gas; an outer axially elongated generally cylindrical receptacle spacedly surrounding said inner receptacle and defining an evacuatable space therewith, said outer receptacle comprising at its ends a pair of opposing shell members and an intermediate member sealingly connected to said shell members and disposed between the shell members, said intermediate member being formed unitarily with stiffening formations preventing radial expansion and contraction but permitting elastic axial expansion and contraction; and support elements engaging said shell members and supporting said outer receptacle on said inner receptacle, said shell members being formed as dome cylinder bottoms and said intermediate member being a cylindrical wall, said formations extending circumferentially on said wall, said wall being corrugated with the corrugations having crests and troughs lying in planes perpendicular to the axis of said outer receptacle, said inner receptacle having cylinder bottoms at opposite ends thereof, said support elements being rigidly connected to said cylinder bottoms of said inner receptacle.
Claim 3
Dependent Claim
44 words
The vessel defined in claim 1, further comprising a support frame extending continuously beneath said outer receptacle, fixed mounts on said frame engaging one end of said inner receptacle, and longitudinally yieldable mounts on said frame engaging the opposite end of said inner receptacle.
Claim 4
Dependent Claim
54 words
The vessel defined in claim 1, further comprising frame means having a pair of divided frame sections beneath said outer receptacle, fixed mounts on each of said frame sections each engaging a respective end of said inner receptacle, and longitudinally yieldable mounts between each frame section and portions of said receptacle intermediate said ends.
