Apparatus for developing films

Abstract

Abstract AN APPARATUS FOR DEVELOPING STILL PICTURE FILM, PARTICULARLY COLOUR FILM, OF VARIOUS SIZES COMPRISES A TRANSPORTABLE HOUSING WHICH FULLY ENCLOSES A DARK SECTION AND AN ILLUMINATED SECTION CONTAINING THE NECESSARY PROCESSING TANKS FOR DEVELOPING FILMS, AND A DRYING SECTION. THE HOUSING DOES NOT INCLUDE A SECTION FOR ILLUMINATING THE FDEVELOPED IMAGES ON THE FILMS. EACH SECTION IS EQUIPPED WITH A CONVEYOR FOR CARRYING THE FILM THROUGH THAT SECTION AND A MECHANISM FOR TRANSFERRING THE FILMS FROM THE DARK SECTION TO THE ILLUMINATED SECTION AND FROM THE ILLUMINATED SECTION TO THE DRYING SECTION. PREFERABLY THE CONVEYORS IN THE DARK SECTION AND ILLUMINATED SECTION ARE ARRANGED TO IMMERSE THE FILMS IN EACH TANK A NUMBER OF TIMES BEFORE CARRYING THEM TO THE NEXT TANK, THE FILMS BEING COMPLETELY REMOVED FROM EACH TANK BETWEEN SUCCESSIVE IMMERSIONS. A SUBSTANTIAL PORTION OF AT LEAST ONE OF THE WALLS OF THE HOUSING IS TRANSPARENT SO THAT A WATCH CAN BE KEPT IN THOSE PROCESSES WHICH DO NOT HAVE TO BE CARRIED OUT IN DARKNESS. THE HOUSING IS PREFERABLY AIR CONDITIONED AND ITS ATMOSPHERE CONTROLLED, AND INSTRUMENTS MAY BE PROVIDED FOR MONITORING THE ENVIRONMENTS IN THE APPARATUS.
