1. A vessel for cryogenic fluids and the like, comprising:

  • a plurality of longitudinally extending containers supported one within another in spaced apart relation, one of said containers being an inner storage container adapted to receive such fluid therein, a second thEreof being an intermediate heat shield enclosing the inner container, and a third being an outer jacket enclosing all of said containers; and

    support means interconnecting said containers to maintain the same in spaced apart relation and at the same time minimize conductive heat migration through the support means between said outer and inner containers, said support means including transverse support structure providing adjacent each end of said vessel a plurality of relatively thin and narrow spaced apart inner transverse supports substantially confined within the space between said inner storage and intermediate heat shield containers and extending outwardly from the center portion of said inner container at each end thereof generally adjacent its longitudinal axis to the outer portions of said heat shield generally adjacent its cylindrical surface to interconnect the same adjacent the ends thereof, said transverse support structure further providing adjacent each end of said vessel a plurality of relatively thin and narrow spaced apart outer transverse supports substantially confined within the space between said intermediate heat shield and outer jacket containers and extending outwardly from the center portion of said heat shield at each end thereof generally adjacent its longitudinal axis to the outer portion of said outer jacket generally adjacent its cylindrical surface to interconnect the same adjacent the ends thereof, said inner and outer transverse supports disposed in structural parallelism and functional serialism and being relatively long with the length of the thermal path defined thereby between said inner container and outer jacket being materially greater than the transverse distance therebetween to define relatively long thermal paths restricted in cross sectional area and effective to reduce conductive heat migration therethrough.
