摘要： This invention pertains to an ultrafiltration process which maintains a constant developer strength in a printing plate developing operation. Such a process enables development of more plates than conventional processes while using less developer and generating less liquid waste. The ultrafiltration process is suitable for both batch and continuous plate development operations. By this process, used developer is filtered and the fluid portion returned to the working developer solution. The filtered out remainder mass is treated with an absorber to convert it into a solid.

摘要： Coating is removed from polyester film which is formed into flakes by use of an alkali stripping solution containing surfactant wherein the surfactant is not optimized in a stripping step to remove redeposited coating but rather is optimized to aid in rinsing based on residual surfactant present on the stripped flake.

摘要： A process is described for recovering cellulose triacetate from scrap photographic film, using aqueous solutions free of organic solvents, by the steps of:a) reducing the film to segments of handlable size;b) oxidizing the film with an oxidizing agent comprising an alkali metal permanganate and a strong acid;c) oxidizing the product of step b) with an alkali metal hypochlorite to remove stain from iron compound and yellow dye;d) bleaching the product of step c) with an alkali metal metabisulfite in an acidic environment; ande) recovering cellulose triacetate.The recovered cellulose triacetate prepared in accordance with this invention has essentially the same spectral absorption at 400 nm as virgin cellulose triacetate and can be used to prepare photographic film base of acceptable color purity.

摘要： Silver is recovered from the rinse water from a photographic film processing unit by means of a silver recovery device in which the rinse water is passed through at least one bed of ion exchange resin particles maintained in fluidized condition by the water flow. A plurality of such beds are preferably connected in series with rinse water being recirculated until fresh rinse water causes overflow to the next bed and finally to a collection vessel. Fluidization is interrupted periodically to create quiescent periods which aid in removal from the resin particles of accumulated gelatin from the processed film.

摘要： A process for recovering a support from a photographic film is disclosed. The photographic film comprises the support and an undercoating layer provided thereon. The support is made of cellulose triacetate film base. The undercoating layer contains gelatin and cellulose nitrate. According to the present invention, the process comprises the steps of: (I) treating the photographic film with an aqueous solution of a surfactant; and then (II) treating the photographic film with an aqueous solution of a protease to remove the undercoating layer from the support. The aqueous solution of the protease used at the step of (II) preferably further contains an anionic surfactant. It is also preferred that the process further contains the step of (III) treating the recovered support with an aqueous solution of hydrogen peroxide to bleach the support.
