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.
