    • Apparatus for processing exposed photosensitive elements comprising: a cylindrical container having an open end and having a plurality of circumferentially disposed containment vessels for containing processing fluids; an index plate which is rotatably mounted on the container at the open end; a holder for holding an exposed photosensitive element; support structure for mounting the holder on the index plate for movement downwardly and upwardly; and a member on the index plate for manually rotating the plate to sequentially align the holder with the plurality of containment vessels so that at each vessel the holder is manually moved downwardly to submerge the photosensitive element in the processing fluid contained in the vessel and then moved upwardly to remove the element from the fluid.
    • 用于处理曝光的感光元件的设备,包括:具有开口端的圆柱形容器,并具有多个周向设置的容纳容器,用于容纳处理流体; 折板,其在开口端可转动地安装在容器上; 用于保持曝光的感光元件的保持器; 支撑结构,用于将保持器安装在分度板上用于向下和向上移动; 以及用于手动旋转板以使支架顺序地与多个容纳容器对准的构件,使得在每个容器处手动地将保持器向下移动以将感光元件浸没在包含在容器中的处理流体中,然后移动 向上以从流体中去除元件。

    • Black-and-white elements, such as radiographic films, can be processed in roomlight because they include certain light absorbing dyes and desensitizers. Processing of such elements can be achieved using a processing kit and a two-stage process carried out in the same light- and fluid-tight processing apparatus. In the first stage, development is initiated with a developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent and a sulfite. After an appropriate time, a non-sulfite fixing agent is introduced into the processing apparatus or container to provide a combined developing/fixing composition, and development and fixing are carried out simultaneously. The processing method is carried out quickly, usually within about 90 seconds. The presence of sulfite and high pH in both stages decolorizes or deactivates the particulate dyes. The processing kit includes the photographic element, a vessel containing a developing composition, a vessel containing fixing composition, and a light-tight, hand-held container for holding an exposed element as it is inserted into the first and second vessels to carry out processing.
    • 黑白元素,如放射照相胶片,可在室温下进行处理,因为它们包括某些光吸收染料和脱敏剂。 可以使用在相同的光和流体密封处理装置中执行的处理套件和两阶段处理来实现这些元件的处理。 在第一阶段中,开发具有pH为约10至约12.5的显影组合物,并且包含适当的黑白显影剂和亚硫酸盐。 在适当的时间之后,将非亚硫酸盐固定剂引入加工设备或容器中以提供组合的显影/定影组合物,同时进行显影和定影。 处理方法快速进行,通常在约90秒内。 两相中亚硫酸盐和高pH值的存在使颗粒状染料脱色或失活。 处理套件包括照相元件,含有显影组合物的容器,含有定影组合物的容器,以及用于在暴露元件插入第一和第二容器中时保持暴露元件的不透光手持式容器,以进行处理 。
