Abstract
Procédé de régulation du circuit de l'ammoniac dans un appareil de développement utilisé pour le développement du matériel de diazocopie, caractérisé en ce que le mélange de gaz ammoniac et de vapeur d'eau provenant de l'évaporateur est transformé entièrement par le phénomène de la condensation en eau ammoniacale, à teneur en ammoniac relativement élevée, que l'eau ammoniacale est stockée dans un réservoir d'alimentation et que l'eau ammoniacale s'écoulant de ce réservoir d'alimentation est dirigée, sous forme d'un flux constant, dans un évaporateur qui est directement relié à la chambre de développement et qui dirige le mélange de gaz ammoniac et de vapeur d'eau ainsi produit par évaporation, dans la chambre de développement à laquelle il est relié.
