Processing Unit

The third unit is a high speed processing unit designed to develop, rinse, fix, wash, and dry exposed 35mm. positive film so that it is ready for use in a standard 35mm. projector in a matter of seconds. This unit processes film at a synchronous sound projector speed of 90 feet per minute, 24 frames per second and using high temperature, high pressure spray techniques. It is claimed that the film quality using these techniques is equal to, or even superior to, standard release quality. It is completely automatic, with one switch starting the camera, processing machine drive and theatre projector. Drying is accomplished by a squeegee in conjunction with hot air. All temperatures are thermostatically controlled and all componets are interlocked so they start and stop simultaneously. The completely processed and dry film may be fed directly from this unit into the standard 35mm. projector, or taken up on a take-up reel provided at the end of the machine for later presentation. The film used in this unit is standard fine grain release safety positive film. Solutions are available

in package form so that the operators


can mix solutions merer by adding water. lnsiallaiion

The compact nature of the ttInterFilmil Theatre TV unit is one of the important features that makes it practical for most houses. In the great majority of cases theatres already have most of the facilities needed for the installation of such a system, with no major alterations or additions necessary. Approximately 60 square feet of floor space is required to house the unit. Although the most favorable location is as close to the projection booth as possible, it can be to the side, above, below or behind it and not lose any of its efficiency. The processed film is run through accessible chutes to the theatre projector from the TV unit. Up to the present time runs up to 100 feet, with as many turns as are necessary, have been used with no difhculty. This means that no seats will have to be sacrified in order to make room for the unit.

Power. Wa'l'er RequiremeMs

As for power requirements, a threephase, three-wire, 220-volt service and a single-phase, llO-volt service are needed for the operation of this equipment. Both of these services are usually readily available in the theatre booth.

The plumbing needs again offer little of a problem. Hot and cold water is required at normal temperatures and pressures, with an ordinary drain needed in the door. Water lines need not be large, since total water consumption is approximately the same as in the ordinary drain needed in the floor. Water lines need not be large, since total water consumption is approximately the same as in the ordinary sink. The water is mixed automatically to maintain a temperature of 1200F. and is used for washing the processed film. The drain is needed for quick disposal of photographic solutions and wash water.

The exhibitor should also see to it that there are enough red and white lights. They should be on separate switches and are needed in the unit area to supply uniform illumination. The red lights are used during the operating period. Another requirement which should be supplied is a sink somewhere near the area in which the equipment is located, in order to facilitate the mixing of the packaged chemicals. If there is enough floor space, a table next to the sink is desirable. An item not to be overlooked is proper storage space,
