Abstract: It is known to apply processing solution to photographic material using a high speed moving surface. High speed rotating drums have been used to transfer processing solution from a reservoir to the material. Horizontal belts are also known. However, such arrangements require large volumes of processing solution in order to operate effectively. Described herein is a processor (1) comprising a vertically mounted high speed belt (10) which both transfers processing solution (26) from a reservoir (20) onto photographic paper being processed, and provides agitation at the paper surface. Two transport belts (30, 32) are provided, one on either side of the belt (10) to assist in the transport of paper through the apparatus. An arrangement according to the invention has the advantages that only low volumes of processing solutions are required, good surface agitation is provided, and it can be fitted into conventional photographic processing apparatus.

Abstract: It is known to dry photographic paper using radiant heat and air streams passing over the surface of the paper. However, it is important that the paper is not over- or under-dried. Described herein is a method and apparatus which dries photographic paper without the risk of over- or under-drying it. This is achieved by sensing the moisture remaining in the paper after it has passed through an initial heating stage, and using the sensed moisture content to control the power supplied to heaters and other devices in subsequent heating stages which assist in the removal of moisture from the paper.

Abstract: It is known to treat the effluent resulting from photographic processing apparatus. Such treatment takes the form of either neutralization where the effluent is mixed with a neutralizing solution prior to disposal, or evaporation where the effluent is heated to form a precipitate and a concentrated liquid portion prior to disposal. However, both these techniques have disadvantages they do not account for toxic particles which may be suspended in the solutions. Described herein is apparatus in which photographic effluent can be treated to provide harmless end products which can be disposed of directly. The apparatus comprises a mixing unit (10) in which the effluent (S1) is mixed with treatment chemicals (S2, S3, S4, P1, P2, P3) and is then passed to a separation unit (20) in which the treated effluent is separated into non-toxic liquid and solid phases. A computer (100) is used to control all stages of the treatment of the effluent.

Abstract: A method of treating photographic effluent containing one or more metal ions with an oxidation number greater than one, comprising the addition of a water-soluble silicate to the effluent in an amount to render it glass-like and less permeable to water. Conveniently the effluent has been treated by the addition of calcium hydroxide and the silicate, preferably 'water-glass' may then be added either to the treated effluent suspension and the mixture separated or to the pre-separated solid.

Abstract: A method of separation of a precipitate from a treated or untreated photographic processor effluent by the addition of an inert powder of high bulk prior to filtration or settling. The inert powder may be a diatomaceous earth, such a kieselguhr, or aluminium hydroxide or wet sawdust. The separation time and the pressure required to give rapid filtration is reduced. The rate at which the solid phase will settle is similarly improved.
