Abstract
The interior chamber of a tanker is subdivided into at least two compartments by a partition wall that is formed of Invar steel and is at the same temperature as the liquids in the two compartments. The partition is rigidly secured to the bottom wall of the tanker and generally planar, with limited ability to expand and contract in the direction of its plane. This is effected by forming the partition of one or more upright tubes of round or square cross section interconnected, if desired, by webs lying in or at an angle to the plane. It is also possible to connect the outer edge of the partition to the side wall of the tanker by means of a panel tightly secured in a frame but slidable relative thereto to allow limited expansion and contraction.
