The Straight Line Developing Machine

IN MY PAPER at the Ottawa convention I treated a friction feed developing machine in which the film was fed spirally through the various units. A casual observation of the field has led me to believe that by far the largest percentage of machines in use today are what I term straight line machines. I have coined this name because in these machines the film is fed along a series of loops in the same perpendicular plane. (Fig. No. 1 illustrates a straight line tube machine. Fig.No. 2 illustrates a straight line tank machine.)
