Abstract

L'invention concerne un appareil perfectionné de diazocopie. Elle se rapporte à un appareil qui comprend une chambre de développement, un dispositif de transport, une première enceinte entourant la chambre et l'isolant de l'atmosphère, une seconde enceinte contenant la première et l'isolant de l'atmosphère, et un tube perforé d'aspiration destiné à collecter l'ammoniac qui s'échappe de la première enceinte et à retirer l'ammoniac des copies développées avant leur sortie à l'atmosphère Les gaz passent dans un dispositif d'absorption d'ammoniac. Application à la réduction des émissions des appareils de diazocopie.
