SUBJECT Trip Report
1. On 13 March 1967, a visit was made
25X1A
to investigate a company developed motorized film transport system. A 25X1A
bread board model had been fabricated and it performed very well.
2. The system consists of employing a printed circuit torque motor to
each reel. There are three modes of operation, all controlled by a single
handwheel. The first mode consists of the operator rotating the handwheel
in the direction and at the rate he desires to transport the film. The rate
and direction of handwheel rotation generate appropriate signals to drive
the motors. Therefore, all of the torque required to advance the film is
supplied by the motors. This mode of operation gives extremely fine control
over the film for precise positioning.
3. The second mode of operation consists of a scanning drive. The
operator merely pulls the handwheel out axially to the first detent position.
The handwheel now controls a potentiometer, whereby the angle of rotation of
the handwheel relative to a null position determines the speed and direction
of film transport. One important feature of this mode is that it provides a
relatively constant film velocity for the entire reel once the operator deter-
mines what speed he desires.
4. By pulling the handwheel to the second detent position, a slew or
rewind capability can be achieved. As in the above two modes this system is
very positive in that regardless of the fi:Lm speed employed there is no film
looping or spillage. A maximum velocity of 11 ft/second can be achieved and
is constant over the entire reel as in the second mode.
5. 1.s also initiating a program to investigate inorganic photochr- 25X1A

6. agreed to submit an unsolicated proposal to develop a light source
