Abstract: A method of and an apparatus for the storage of biological materials at low temperature provides the biological material in containers (biotainers) which are displaced in a vessel subject to low temperature cooling along a closed path. The movement of the biotainers along this closed path has been found to reduce deterioration and increase the storage life thereof. The system is principally effective for the storage of blood.

Abstract: A heat exchanger, reactor or like apparatus capable of carrying out heat exchange, material exchange or combinations thereof, comprises a cylindrical housing formed at one end with a cover and provided internally with a cylindrical partition carried by the cover and reaching toward but terminating short of the opposite end of the housing to subdivide the interior into an inner chamber or space and an outer annular chamber or space. A first fluid is fed to a helical-coil tube bundle in the outer space and then passes into a helical-coil tube bundle in the inner space before being discharged through a manifold and pipe in the cover disposed centrally. The inlet pipe or pipes are also carried by the cover outwardly of the central pipe. The conduits for the second fluid which open into the spaces and which pass around the heat exchanger pipes in these spaces are also carried by the cover and may extend coaxially with the first fluid conduits.

Abstract: An arrangement for the transport of low-temperature fluids, especially liquefied gases such as natural gas (i.e. methane) in a vehicle such as a sea-going vessel having a thermally insulated cargo compartment. The liquefied-gas storage container, composed of metal, has at least one side extending generally parallel to the wall of the compartment and is secured thereto against displacement perpendicular to this wall with at least one degree of freedom of movement relative to this wall in a direction parallel thereto. The storage container is constituted of a multiplicity of individual upright receptacles fastened together at theri outer peripheries at upper and lower portions into at least one group of receptacles capable of thermal expansion and contraction, the storage container being anchored to the juxtaposed wall of the cargo compartment at upper and lower portions enabling relative horizontal movement of the container parallel to the wall.
