Title (EN) PHOTOGRAPHIC PROCESSING APPARATUS
(FR) APPAREIL DE TRAITEMENT PHOTOGRAPHIQUE
Abstract:
(EN) In photographic processing, the chemistry needs to be replenished periodically in order to produce optimum results. Known replenishment systems utilise replenishers in liquid form which are dispensed according to volume. These systems require the use of a pump which is both accurate and relatively inexpensive. Described herein is a replenishment system which uses a weighing system with a series of intermediate containers to dispense replenishment materials. The system comprises a weighing device (2) which has three intermediate containers (11, 21, 31) supported on it. Each container (11, 21, 31) is connected to its associated processing stage (10, 20, 30) by a pipeline (12, 22, 32). Flow of replenisher materials from each container (11, 21, 31) is controlled by respective valves (13, 23, 33) which are interfaced with a computer (3). The computer (3) is also interfaced with the weighing device (2) and monitors the decrement in weight of the intermediate containers (11, 21, 31) so that the exact amount of replenisher materials can be added.
(FR) En traitement photographique, il est nécessaire d'effectuer un remplissage périodique des réservoirs de produits chimiques afin d'obtenir des résultats optimum. Les systèmes de remplissage connus utilisent des produits de remplissage sous forme liquide distribués en fonction du volume. Ces systèmes nécessitent l'utilisation d'une pompe à la fois précise et relativement économique. L'invention décrit un système de remplissage qui utilise un système de pesage possédant une série de réservoirs intermédiaires servant à distribuer les matières de remplissage. Le système comprend un dispositif de pesage (2) pourvu de trois réservoirs intermédiaires (11, 21, 31) reposant sur celui-ci. Chaque réservoir (11, 21, 31) est relié au stade de traitement correspondant (10, 20, 30) par une conduite (12, 22, 32). La sortie des matières de remplissage de chaque réservoir (11, 21, 31) est commandée par des soupapes respectives (13, 23, 33) reliées à un ordinateur (3). L'ordinateur (3) est également relié au dispositif de pesage (2) et contrôle la perte de poids se produisant dans les réservoirs intermédiaires (11, 21, 31) afin de compenser la quantité exacte de matière de remplissage.
