摘要:
@ A film developing machine adapted to operate under full light conditions and comprising a charging section for charging film support frames, a series of tubs containing chemical baths, a system for conveying the frames through said tubs, and a drying and discharge section. Each section of the machine is enclosed in a light-protected envelope, and the charging section is provided with a carriage for conveying the frames and an opening for positioning the frames on a transfer carrier of said conveyor system, said opening being adapted to be closed by a closure. Synchronization means is provided for ensuring proper transfer of the frames from said transfer carrier to said conveyor system for conveyance through said tubs.

A device for coupling a strip of photographic paper to a conveyor belt in a developing machine comprises a rod to which the paper strip is attached. The rod has a hook-shaped end portion for gripping one lateral edge of the flat conveyor belt. Slidably mounted on the rod is a slide member formed with an obliquely projecting lip for gripping the opposite lateral edge of the belt. A spring-biased toggle linkage is effective to retain the slide member in the engaged position, in which the belt is resiliently compressed between the hook-shaped end portion of the rod and the lip of the slide member.

@ A device for attomatically metering chemical products in a developing machine comprises pump means (2) and valve means (4). An electronic program unit (6) including a memory is connected on the one hand to a photocell (8) sensing the quantity of paper (7) treated, and on the other hand, to a pulse counter (3) and to an electrovalve (4) so as to constantly monitor the consumption of substances from the treatment bath and to actuate said valve means for regenerating the chemical substances contained in the treatment vessel (5).

摘要:
Die Vorrichtung weist eine im Aufbau herkömmliche automatische Belichtungseinrichtung (30) mit Farbkorrekturfiltern (12, 12') im Lampenhaus (11) und zusätzlich eine Farbfernseheinrichtung (32) für die visuelle Beurteilung jeder nach dem Belichten und Entwickeln zu erwartenden Kopie einer Farbaufnahme (5) auf. Zur Erzeugung des Farbfernsehbildes auf dem Monitorbildschirm (37) werden von einem Rechner aus gemessenen Farbdichtewerten der Farbaufnahme (5) Steuerungswerte für die Farbfernseheinrichtung (32) errechnet, mit denen das Farbfernsehbild eine Wiedergabe der auf dem Aufzeichnungsmaterial (20) zu erwartenden Kopie wird. Wenn das Farbfernsehbild als gut beurteilt wird, erfolgt die Belichtung mit errechneten Kopier-Belichtungswerten. Ein mangelhaftes Farbfernsehbild wird mit geeichten Stellelementen (54) in Helligkeit und/oder Farbbalance korrigiert, und vom Rechner (27) werden aufgrund der vorgenommenen Korrekturen korrigierte Kopier-Belichtungswerte errechnet, mit denen das Aufzeichnungsmaterial (20) belichtet wird. Korrekturverstellungen brauchen daher nur bei den Farbaufnahmen vorgenommen zu werden, die mit der Belichtungseinrichtung (30) eine unbefriedigende Kopie ergeben würden. Damit wird eine grosse Arbeitsleistung erzielt, und Ausschusskopien werden weitgehendst ausgeschlossen.
