52 HARSH AND SCHADLICH July dependent to a great extent on the quality of processing which could be realized and the flexibility of the machine for experimental changes. In order to obtain a smooth screen quality every attempt has been made to provide the optimum developer turbulence conditions based on the available experience from the industry and consistent with other requirements. The basic design is the same as the Ansco 4C 16-mm color machine described by Forrest.1 Substitution of 35-mm spools results in a Fig. 3 — White-light section of processing machine. lower machine speed of 30 feet per minute which for experimental purposes is quite adequate. The bottom-friction-drive principle, combined with an underdriving take-up spool, provides a smooth motion of the film through the machine which is very important for effective use of the high-pressure jet agitation system which will be described below. The first section of the machine consists of the elevator and seven spool banks in four tanks. This section accommodates the first development, short stop, and hardening steps of reversal processing and when in operation is in no light. A lighttight pass box is
