Definitions

  • This invention relates to photographic processing apparatus and is more particularly concerned with the supply of replenishment and clean-up chemistry for use in such apparatus.
  • Replenishment processes are well known in the art and comprise replacing components in a photographic process which become used up during the processing or which deteriorate due to age and/or oxidation.
  • WO-A-91/17478 discloses a method of reducing the amount of retained developing agent in a photographic material by subjecting a processing solution through which the material passes after development but before washing to the influence of an absorbing agent.
  • the absorbing agent may be an ion exchange resin or an activated carbon.
  • British patent application no. 9208185.0 discloses a method of processing photographic material in which wash water or stabilizer solution is treated with an absorbing agent in order substantially to reduce the amount of retained developing agent in the solution.
  • a chemical supply unit for use with a photographic processor having at least one processing stage, the unit comprising a plurality of compartments characterized in that at least one compartment contains replenishing chemistry for the photographic processor, and at least one other compartment contains chemical components for treating such chemistry.
  • replenishment chemistry and clean-up chemistry can be housed in a single unit having a plurality of compartments, each compartment containing either replenishing chemistry or clean-up chemistry.
  • FIG. 1 illustrates a combined replenishment/clean-up unit 10.
  • the unit 10 comprises a plurality of compartments 20, 22, 24, 26, 30, 34 each containing either replenishment chemistry or clean-up chemistry.
  • compartments 20, 22, 24, 26 contain replenishment chemistry and compartments 30, 34 clean-up chemistry.
  • compartments are shown as two separate sets, namely, replenisher and cleaner, the compartments may be intermingled in the unit as desired. Furthermore, there may be a greater or fewer number of each type of compartment according to the type of photographic process carried out in the processor to which the unit is to be attached.
  • compartments are filled as follows:- compartment 20 contains developer; compartment 22 contains base; compartment 24 contains bleach-fix (blix); compartment 26 contains stabilizer; compartment 30 contains blix cleaner; and compartment 34 contains stabilizer cleaner.
  • each replenishment compartment 20, 22, 24, 26 has a single inlet/outlet 21, 23, 25, 27 respectively.
  • the chemistry contained in each of these compartments is removed as required by means (not shown) and fed to an appropriate stage in the photographic processor to which the unit 10 is connected.
  • Each clean-up compartment 30, 34 has an inlet 31, 35 and an outlet 32, 36 respectively.
  • Each inlet 31, 35 is connected to the appropriate processing stage of the processor for receiving used processing chemistry contained therein for treatment.
  • Each outlet 32, 36 can either be connected to the associated replenishment compartment (not shown) or to the appropriate processing stage as desired.
  • the processor (not shown) is fitted with needles arranged to pierce septa (not shown) provided in the outlet 21, 23, 25, 27, 32, 36 of each compartment 20, 22, 24, 26, 30, 34 of the replenisher/clean-up unit 10 to provide the appropriate connections for the transfer of processing chemistry.
  • compartments 20, 22 contain replenisher components for the developer chemistry.
  • Colour developer is contained in compartment 20 and the remaining components are contained in compartment 22.
  • These components are well known in the art and will not be described here.
  • the two component parts of the developer chemistry are added to the developer tank of the processor, as required, by drawing solutions through the needles by means of a suitable pump (not shown).
  • Compartments 24, 26 are filled with conventional bleach/fix and stabilizer replenishers respectively which are used to replenish the appropriate processing tank in the processor (not shown). As before, a suitable pump (not shown) is used to draw each of the bleach/fix (blix) and stabilizer chemistries into the appropriate processing tanks.
  • Compartment 30 contains carbon as the blix cleaner to remove developer and its derivatives from the blix solutions.
  • the method of operation of this cleaner is described in WO-A-91/17478 mentioned above.
  • Compartment 34 also contains carbon. However, in this case, the carbon is used to remove organic species. Ion-exchange resins are also present in compartment 34 for removing ionic species from the stabilizer solution. The method of operation of this cleaner is described in British application 9208185.0.
  • FIG. 2 illustrates another combined replenishment/clean-up unit 100 which can be used with different photographic chemistry, for example, it can be used with a colour paper processor which uses redox amplification chemistry.
  • the unit 100 comprises a plurality of compartments 110, 120, 130, 140, 150 each containing either replenishment or clean-up chemistry as described above.
  • compartment 110 contains developer
  • compartment 120 contains bleach-fix (blix)
  • compartment 130 contains wash or stabilizer
  • compartment 140 contains wash or stabilizer
  • compartment 150 contains wash or stabilizer and ion exchange resins as indicated by the numeral 160.
  • each compartment 110, 120, 130, 140, 150 has a respective inlet/outlet 112, 122, 132, 142, 152 as shown.
  • the chemistry can be dispensed using gravity, and once used can be pumped back into the respective compartments by means not shown.
  • Units 10, 100 in accordance with the present invention provide convenient means of adding processing chemistry to a processor.
  • a unit could be supplied along with the product, thereby making delivery and distribution easy.
  • the unit provides a means of supplying chemicals and clean-up chemistry in a form in which the operator of the processor does not come into contact with the chemistry. This is advantageous when considering the health and safety of the operator.
  • the unit in accordance with the present invention may be of any desired size according to the processor to which it is to be connected.
  • the unit may be small to fit in a desk top processor.
  • Each compartment of the unit may be filled directly with the desired chemistry.
  • the unit may simply house chemistry in a flexible container such as a plastic bag.
  • Plastic bags may be filled at remote sites before insertion into the appropriate compartment of the unit.
  • the unit itself may be recyclable - the top being screwed down and the screws being removed after return for refilling etc.
  • replenishment and clean-up chemistry may be more convenient to have only some of the replenishment and clean-up chemistry in a given unit.
  • one unit may contain replenishment and clean-up chemistry for the developing stage only of the processor.
  • one or more compartment may be provided which contains wash water for the processor.
  • Water may also be included for the automatic washing of rollers in the processor before or after it is switched off. This is to prevent crystallization build up on moving parts of the processing apparatus.
  • the unit according to the present invention may be used with any suitable photographic processor, for example, film or paper processors and/or black-and-white or colour systems.
  • the unit according to the present invention can be fitted to existing processors replacing currently used replenishment tanks.
  • each outlet and/or inlet may be covered for transportation - the covers being removed when the unit is correctly located.
