Abstract

Cette installation est du type décrit au brevet principat Suivant l'addition il est prévu à l'intérieur de l'enceinte ou carter en forme de boîte des dispositifs de séparation ou de cloisonnement transversal pouvant prendre deux positions dont la première, dite position d'ouverture, permet le passage de l'air et dont la seconde, ou position de fermeture, ne permet pas le passage de l'air, en réalisant une étanchéité à peu près complète à l'air, le dispositif de cloisonnement, en position de fermeture, constituant la ligne de séparation des deux régions amont et aval. Le nombre de ces dispositifs de cloisonnement transversal est d'au moins trois et, lorsque l'installation est en fonctionnement, seul l'un d'entre eux se trouve en position de fermeture, formant ainsi, suivant le type de mousse fabriqué, un volume donné constant pour les régions amont et aval, ce volume pouvant cependant etre modifié d'un type de mousse à l'autre.
