    摘要： It is known to wash dispersion noodles in a `batchwise` fashion in which the noodles are retained in a kettle or kettle and water is sprayed onto the surface of the noodles. Agitation is achieved by bubbling air into the kettle from the bottom. Described herein is a method and apparatus for continuously washing dispersion noodles. The apparatus includes continuous pipe work in which the noodles are washed, the pipe work including at least one separating device (10) for separating the noodles from the water in which they have been washed. The device (10) comprises a housing (12) having an inlet (14) and an outlet (16). A separating element (22) is located in the housing (12) between the inlet (14) and the outlet (16) and is surrounded by a collection chamber (24), the element (22) comprising a tube of mesh material through which water passes into the collection chamber (24) and which is then drained off through drain (32). The housing (12) includes jets (28, 30) through which water, hot or cold, or steam can be introduced for cleaning the device (10). Water jets (34, 36) are provided in the outlet (16) for introducing clean water to the noodles.

    摘要： A method of gelation of a photographic emulsion, oil in water emulsion, or a gelatin-containing solution comprising continuously rapidly cooling the photographic emulsion, oil in water emulsion, or the gelatin-containing solution, which has good thermal efficiency and requires no adjustment of the amount of water contained in the rapidly cooled product prior to use, and a unit therefor comprising a static mixer-installed double pipe for rapidly cooling the photographic emulsion, oil in water emulsion, or the gelatin-containing solution by a conduction type heat exchange system, and a double pipe without static mixer for conveying the rapidly cooled product to a storage vessel while avoiding adhesion of the rapidly cooled product transformed into a gel state to the inside surface of the inner pipe of the double pipe by warming the inner pipe with water kept at 30.degree. C., although transformation of the rapidly cooled product to a gel state successively proceeds in an inner portion of the inner pipe.

    摘要： Photosensitive matting agents for photosensitive recording materials that are known can be prepared only at considerable expense. A much simplified process involves preparing a photosensitive matte material from photoinsensitive matting agent particles by incorporating the particles into the starting solutions for the silver halide precipitation. The invention is particularly useful in reprography and in medical diagnostics.

    摘要： An object of the invention is to overcome disadvantages of prior practices. A further object of the invention is to provide a process for providing particles that result in improved UV absorption in photographic products.An additional object is to provide lower cost polymer particle dispersions.The invention is generally accomplished by mechanically grinding a crystalline material to a desired particle size in a liquid that is not a solvent for the material, heating said crystalline particles dispersed in said liquid to above their melting temperature, and cooling the melted particles in said liquid to form amorphous particles. In preferred forms of the invention, the material is a photographically useful material, such as ultraviolet light absorber or coupler.
