Abstract: An arrangement for developing photomaterials has a rotatable drum arranged to accommodate a photomaterial, a plurality of vessels for various treatment fluids, an arm having a free end rotatably connectable with the drum and turnable together with the latter between a substantially horizontal initial position for supplying a treatment fluid from one of the vessels into the drum for treatment of the photomaterial and an inclined emptying position for discharging a used treatment fluid from the drum after the treatment, a guide arranged so that the vessels are located near one another in a stack and displaceable to the drum for filling the latter, a stepping element including the arm and arranged to displace the vessel of the stack by a respective one of the vessels in a cycle with the turning of the arm, and a lifting member provided on the arm and arranged so as to upwardly tilt the vessel which has been displaced to the drum, to its pouring position of the treatment fluid.

Abstract: A spool for developing (and optionally drying) strip-shaped film material has a core and two axially spaced end flanges provided with many large cut-outs so as to leave only a few narrow, spoke-like portions of material. A pair of inserts is provided which are placed against the outer sides of the respective end flanges and have projecting plug-like portions which enter the respective cut-outs. The inner surface of each of these plug-like portions has a plurality of major fragments of the turns of a spiral groove. The inner surfaces of the spoke-like portions have spot-support portions defining on each spoke-like portion a plurality of minor fragments of the turns of the same spiral groove, so as to complete the groove when the plug-like portions are inserted into the cut-outs. The film strip or strips is (or are) then inserted into the groove to spirally surround the core. Thereafter, the inserts are detached from the spool and can be immediately used to load another spool.
