Title: Photographic disc film developing machine with electric motor
IPC: G03D3/08
Filed: 1983-08-24
Abstract: The machine includes a rotating structure with a series of needles hanging down so that each may hold a film disc on its end. The needles are situated above a correspondingly spaced set of containers holding film developing solutions. A mechanism is provided for lifting and lowering the set of needles and rotating them by the space between an adjacent pair to move discs onto the next bath. - A hook (27) is arranged in the path of the film discs to remove discs once they have been immersed in each of the required baths. The discs are held on by friction, and the whole assembly moves according to a timed program.  (0/8) GBAB- GB2125711 B A film disc developing machine having a light-tight casing, means therein for supporting a film unit consisting of an emulsion bearing disc having a hub member secured thereto, with a central hole therein, in a substantially horizontal attitude, means supporting a plurality of vertically extending spindles arranged around a closed path passing over said hole, a plurality of photographic solution containers arranged below said spindles and in a path corresponding to said closed path, means for causing simultaneous relative vertical movements at predetermined intervals between both said means for supporting a film unit and said containers, and said spindles towards and away from each other whereby said spindles are caused to enter said solution containers and after a predetermined time are withdrawn from them and for moving said spindles, after each movement of said parts away from each other, a distance along said path corresponding to the spacing between adjacent spindles, e one of said spindles being situated immediately above said hole during said relative vertical movements, the lower free end of each spindle being shaped to pass through said hole during movement of said parts towards each other and to engage frictionally in said hole, and support the film unit during processing, the arrangement being such that on each occasion that said parts are moved toward each other, film units are immersed in solutions in said containers and retained therein for a predetermined period before being removed from said solutions whereby, on having been immersed into each of said containers in turn, a film unit is completely developed, means for continuously rotating said spindles about their axes, means for detecting a developed film unit from a spindle and timing means controlling and synchronising the operation ofthe machine. - GB2125711 B A film disc developing machine having a light-tight casing, means therein for supporting a film unit consisting of an emulsion bearing disc having a hub member secured thereto, with a central hole therein, in a substantially horizontal attitude, means supporting a plurality of vertically extending spindles arranged around a closed path passing over said hole, a plurality of photographic solution containers arranged below said spindles and in a path corresponding to said closed path, means for causing simultaneous relative vertical movements at predetermined intervals between both said means for supporting a film unit and said containers, and said spindles towards and away from each other whereby said spindles are caused to enter said solution containers and after a predetermined time are withdrawn from them and for moving said spindles, after each movement of said parts away from each other, a distance along said path corresponding to the spacing between adjacent spindles, e one of said spindles being situated immediately above said hole during said relative vertical movements, the lower free end of each spindle being shaped to pass through said hole during movement of said parts towards each other and to engage frictionally in said hole, and support the film unit during processing, the arrangement being such that on each occasion that said parts are moved toward each other, film units are immersed in solutions in said containers and retained therein for a predetermined period before being removed from said solutions whereby, on having been immersed into each of said containers in turn, a film unit is completely developed, means for continuously rotating said spindles about their axes, means for detecting a developed film unit from a spindle and timing means controlling and synchronising the operation ofthe machine. USAB- US4497559 A Spindles are moved intermittently around a closed path by mechanisms which raise and lower the spindles intermittently. The whole assembly is indexed through a predetermined angle in the raised positions. Each time the spindles are lowered the lower end of the spindle passes through the hole in the hub of a film disc to engage if frictionally. Beneath the path of the spindles several processing solution containers are arranged including at least one for drying. - A disc picked up on the end of a spindle is introduced into each solution in turn and retained in it for a set period. The spindles are rotated about their axes by a common drive to enhance contact between the emulsion and the processing solutions. A disc in the drying container is rotated at a higher speed to throw off surplus solution.
