FOUR MAGNETIC SOUND TRACKS AND
THE PICTURE ON 35MM FILM

At the right is illustrated by a drawing a section of the film which has now simplified and standardized projection of stereophonic sound: The CinemaScope film.

Note that sprocket holes have been narrowed from .110 to .078, requiring a slight reduction in width of the teeth of the intermittent and other sprockets.

A. The new film driven sound mechanism for picking up the four magnetic channels of the CinemaScope film, which is illustrated in the above cut. This is a tight loop, rotary stabilized type and is complete with Pre-Amplifier. (not illustrated).

B. The Anamorphic Lens: Furnished in two sizes, this lens is adjusted to the picture throw by means of the knurled rings and the adjusting scale on the forward section of the barrel.

While the barrel of the anamorphic lens is threaded and fits the threads of some makes and models of projection lens, MOUNTINGS ARE PROVIDED FOR ITS SUPPORT by all manufacturers of projection heads.

The adjustment of these lenses can be checked by the projection of test patterns, designed for that purpose.
