    摘要： A multiple compartment photographic processor particularly adapted to facilitate threading a web to be processed through a predetermined web processing path traveling successively from one processing compartment to another. The ultimate processing web path is defined by two sets of web engaging rollers, one set constitutes web driving rollers mounted above the perspective compartments and the other set constitutes weighted idler rollers positioned in proximity to the bottom of the respective compartments and supported by flexible tape and pulley support systems designed to counterbalance only a portion of the respective weighted rollers. An initial substantially planar threading web path is provided by elevating the idler rollers above the driving rollers to permit the leading end of the web to be passed between the two sets of rollers directly to a takeup roller. The driving rollers are respectively driven through individual clutch mechanisms which are responsive to the positions of weighted idler rollers within their respective compartments so that the clutches are actuated whenever the idler rollers are in their lower-most positions in the compartments and are deactivated when said idler rollers are raised above their lower-most positions. The clutch for the driving roller delivering the web into the next compartment remains disengaged whenever the idler roller in the next preceeding compartment is above its extreme lower position. The clutch arrangement controlled by the idler roller in the last compartment controls the driving connection to the final takeup roller and the entire web transport system constitutes a self-adjusting tension equalizing drive mechanism for the web through its operative processing web path during the operation of the processor unit.

    摘要翻译： 一种多室摄影处理器，特别适用于促进通过从一个处理室到另一个处理室连续传送的预定的纸幅处理路径来加工纸幅。 最终处理幅材路径由两组幅材接合辊限定，一组构成安装在透视隔室上方的幅材驱动辊，另一组构成位于相应隔室底部附近并由柔性带支撑的加重惰辊， 皮带轮支撑系统被设​​计成仅平衡相应加权辊的一部分。 通过将惰辊上升到驱动辊上方来提供初始的基本上平面的螺纹幅材路径，以允许幅材的前端直接在两组辊之间通过卷绕辊。 驱动辊分别通过单独的离合器机构驱动，这些离合器机构响应于它们各自的隔室内的加重空转辊的位置，使得每当惰轮位于隔间中最低位置时离合器被致动，并且当所述惰轮 辊子升高到最低位置以上。 只要下一个前隔室中的惰辊高于其极低位置，用于将纸幅输送到下一个隔间的驱动辊的离合器保持分离。 由最后一个舱室中的惰辊控制的离合器装置控制到最终卷取辊的驱动连接，并且整个卷筒输送系统在操作期间通过其操作处理卷筒纸路径构成用于卷筒纸的自调节张力均衡驱动机构 处理器单元。

    摘要： A uniform developing method of a film for use in an automatic developer in which the film light-exposed is moved in developing solution in a developing vessel, wherein the moving speed of the film is gradually reduced depending on a deterioration rate of the developing solution with respect to the length of the film to be developed.

    摘要： Apparatus for developing film including a shaft rotatably mounted in a film transport rack. The rack includes a film reel loosely mounted on the shaft for rotation therewith when the reel is held against the shaft by film disposed therearound under tension. A stationary brake is associated with the rack for braking the film reel into a stationary position with respect to the shaft independent of the rotation of the shaft when film tension is released from the film reel.
