Total Claims: 9
Claim 1
Independent Claim
275 words
A double-walled fluid container, comprising: an inner tank; an outer tank surrounding and completely spaced from the inner tank; and first and second means for supporting said inner tank from said outer tank at opposite ends of the inner tank and for accommodating axial movement of said inner tank relative to said outer tank as the temperature of the inner tank relative to that of the outer tank decreases and the inner tank contracts relative to the outer tank; said first and second supporting means each comprising an elongated beam of elastically deformable material having low thermal conDuctivity disposed midway between opposide sides of and extending across the inner and outer tanks at said one end of said fluid container, the ends of said beam being spaced radially inwardly from opposite edge portions of the end of the outer tank; support means fixed to the inner tank and free of attachment to but so engaged with said beam intermediate its ends as to support said inner tank from and prevent it from rotating with respect to the beam; and means fixed to the outer tank and engaged with said beam at the opposite ends thereof to support said beam from and to prevent it from rotating with respect to the outer tank, said beam being elastically deformed toward the outer tank intermediate the ends of the beam to an extent such that, as the inner tank contracts and the distance between the inner and outer tanks increases, said beam can restore toward its undeformed configuration to an extent sufficient to maintain the engagement between said beam and the supporting means fixed to the inner tank.
