Materials for the Construction of Motion Picture Processing Apparatus

J. I. Crabtree, G. E. Matthews, J. F. Ross

An analysis is made of the factors which affect the choice of materials to be used for the construction of various types of processing apparatus. Three general classes of material are considered, namely: (1) metals, (2) coated metals, and (3) non-metallic materials. In addition to the direct action of solutions on metals, the possibility of electrolytic corrosion effects must be recognized. The results of an exhaustive series of tests on the effect of photographic solutions on single metals and metallic couples are summarized, including the effect of the materials on the solutions. — Practical recommendations are given regarding materials suitable for the construction of apparatus such as processing machines.
