    Abstract: The invention aims at preventing the risks of deformation and breaking down of the heat exchanger which is part of a plant for the batch treatment of fluids, of the type in which, during active periods which are separated from one another by rest periods, at least one refrigerating fluid is allowed to circulate in first ducts of the exchanger, from the cold end to the hot end of the latter, and at least one calorigenic fluid is circulated in second ducts of the exchanger, from the hot end to the cold end of the latter, characterized in that, during rest periods, heat is introduced at the hot end and cold is introduced at the cold end of the exchanger so as to maintain these two ends at temperatures which are relatively close to those corresponding to the active periods, at least one of these two inputs being supplied by means of a reserve fluid of the plant.

    Abstract: The article of which the verticality is critical, for example a distillation column disposed in a closed envelope, is associated with an indicator of verticality comprising a suspended mass and a locating ring. The envelope, which contains the various inner articles, is placed on a base by means of supports and its inclination with respect to the base is adjusted by controlling the relative position of the mass with respect to the ring. Application for example to cold boxes for the in situ production of gas from air.

    Abstract: Indirect heat exchanger, of the type comprising a series of parallel plates (7) delimiting between themselves passages (8A, 8B; 28, 42, 60) of generally plate form containing undulant spacers (9; 32, 34, 36, 37, 44, 47, 48, 53 to 56). A first assembly (8A; 28, 60) of these passages constitutes thermal exchange passages having structure (3 to 5; 39 to 41, 51) for inlet and outlet of fluids adapted to exchange heat with each other. Over at least a portion of its length and of its width, the exchanger has added passages (8B; 42), in reduced or no heat exchange relation with the thermal exchange passages (8A; 28, 60) and provided to fulfill at least one function in addition to the exchange of heat, namely a function of storing liquid and/or recirculation of liquid and/or liquid-vapor separation.
