A. PRESENT STATUS
November 1966
Unit is ready for delivery except for a
problem with the lamp dimming circuit. This difficulty is discussed
in detail below under Problem Areas. *
Unit has same status plus it requires
assembly of the hi-intensity light sources and final checkout.

B. PROBLEM AREAS
Lamp Flicker
The problem with lamp flicker due to electrical
noise generated by the film transport drive circuit still exists.
A number of approaches are being made to find a simple and economi-
cal solution. These approaches are mainly concerned with isolating
the dimming circuit from those generating noise and the use of
radio interference filtering. Thb manufacturer of the dimming
control circuit has also been consulted and there is a good possibil-
ity that he may be able to suggest an effective filtering configur-
ation or possible even a modification of the dimming circuit to make
it less susceptible to the type of noise present.
Film Tracking
The problem originally encountered on the 25X1
with the tendency for the film to track off to the side when being

transported, does not seem to exist ZDAI
This we beleive
is due to the substitution of polished chrome plated rollers for
the segmented nylon ones originally used. We feel that the lower
friction between the chrome roller and the film reduces the tendency
for the film to "walk off" while being transported.
C. PROJECTED WORK FOR DECEMBER
it is expected that the lmap flicker problem
will be solved the equipment modified and receive final inspection
and be shipped.
Unit will be made ready for inspection by the
customers technical representative.
TO CUSTOMERS FACILITY-11-23-66
I r- visited customers facility
to investigate a pr em The problem was found to be
in the mechanical slip clutches in the film drive system. The unit
was disassembled and the defective parts replaced. Subsequent to
this it was noticed that the film was being transported in an irregula=-
manner. This problem was diagnosed as being caused by the tensioning
rollers which were occasionally droping down to the film surface.
This is caused by the heavier chrome plated rollers which replaced
the lighter nylon rollers taped the rollers in the up
position and indicated that e wou look into what could be done
to increase the return spring force on these rollers.
