Abstract

Procédé et dispositif permettant de produire sur une pellicule diazo, à l'aide de gaz ammoniac, la copie d'un original sur pellicule revêtue d'une émulsion à base de sels d'argent. Le gaz ammoniac passe en circuit fermé sous vide à partir d'un reservoir susceptible d'être chauffé à la chambre de développement d'où il retourne dans le réservoir, en étant au cours de ce processus comprimé dans la chambre de développement et ensuite à nouveau détendu. L'invention est applicable à la diazocopie.Method and device for producing on a diazo film, using ammonia gas, the copy of an original on film coated with an emulsion based on silver salts. The ammonia gas passes in a closed circuit under vacuum from a reservoir capable of being heated to the development chamber from where it returns to the reservoir, being during this process compressed in the development chamber and then to again relaxed. The invention is applicable to diazocopy.
