Abstract
Abstract The invention is a multi-stage support system between the inner and outer vessels of a cryogenic fluid tank. Under low inertial loads the inner vessel is supported in the outer vessel by a flexible beam having low thermal conductivity so as to minimize the heat transfer through the tank. A second stage support engages the inner vessel only after the beam has sufficiently deflected due to increased inertial loadings.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
A tank for storing and transporting cryogenic fluids under varying inertial loads comprising the combination of: an inner vessel adapted to contain cryogenic fluids; an outer vessel substantially surrounding the inner vessel and defining therewith a vauum-tight insulated space around the inner vessel; a multi-stage supporting system including a first support means comprising a beam of flexible insulative material supporting the inner vessel within the outer vessel under low inertial loads; and a second support means of insulative material located between the vessels for high inertial loads, said second support means engaging only when the inertial load on the tank is sufficient to cause the first support means to reach a certain point of deflection, at which point the second support means provides positive support between the vessels for any additional inertial loads.
