Abstract: The flat spiral reel employed for 6-ft lengths of still camera film is one of the most compact types of processing equipment. After preliminary chemical and physical treatment of the loaded reel it is possible to dry the film on the processing reel, thus diminishing the risk of damage in handling. Complete processing units in 30-ft and 50-ft sizes have been built of stainless steel wire welded to flat radials. Other sizes are possible within limits which are discussed. The 2 mated sides were mounted on a reinforced bakelite hub which provides the bearing for rotation of the reel and terminates in a handle at one side. The stainless steel spirals were built by Nikor Products Co. Accessory equipment consists of a rewind for loading and unloading the reel, processing and washing tanks, loose water stripper, and drying cabinet. The intensity of agitation which can be given is limited. Consequently, while the uniformity of development is satisfactory for still photographs, it is not suitable for the most exacting motion picture work, although it may have some application in small-scale motion picture work.
