Mechanical assembly is complete and electrical
wiring is essentially complete with only trouble shooting left.
Unit was shown to the customer's representative in its nearly
completed form on June 20, 1966.
Fabrication of parts is complete with exception
of a few items required.for the high intensity light sources.
Electrical assembly is approximately 50% complete.
PROBLEM AREAS
25X1
It is understood from conversations with the
customer's representative that there are certain characteristics
the noise level of the instrument during operation in various
modes. This noise is objectionable because it is loud relative
to the "~ paswe t F~t#~e~31~~~Q(!'2/@~d8~ie& -R?~'~~4 3~4~iE~l~q.'~4~@ r1to inter-
pretation cubicle. There appears to be three sources of noise;
which he believes are objectionable. One of these is

the light source, the film drive motors, and the nylon film
rollers. With respect to the light source, there is a source of
60 cycle hum which is undoubtedly associated with the SCR dimming
circuit. This hum is present only when there is a particular
sequence of control operation. it may be eliminated by operating
the "loading switch" momentarily. The cause of this trouble is,
at present, still a mystery, however, there is no reason we can
now see why this noise could not be eliminated with electrical
noise filters, or perhaps shielding of sensitive leads. The cause
of this noise is currently being investigated.
In regard to motor noise, the writer sees no
ready solution to the problem. The motors used were selected
because of their small size to fit within the available instrument
envelope. It is doubted whether vibration isolation or acoustical
insulation would appreciably affect the noise level.
With respect to the nylon rollers, the problem
exists only because in certain modes of power assisted or automatic
slew the linear velocity of the film over the rollers is rather
high and causes them to chatter or "sing" due to vibration of the
roller on its shaft. This we are sure can be remedied, but there
is a question as to whether this can be done without exceeding the
target cost of the contract. Our latest cost to complete estimate
shows that we shall spend funds to the target cost level. There
is not much allowance left for changes or improvements. This
necessitates close scrutiny of any further changes or improvements
deemed desirable either or by the customer. 25X1
Another characteristic deemed worthy GJ"
of mention by the customer's representative was the variation in
film speed during slew, and in particular the laboriously slow
speed obtained when approaching the end of a 500 foot spool of

9 inch film. The variation in speed is a characteristic of the
type of drive employed. The overall speed of transport could be
increased somewhat by the replacement of the motors with those
wound for higher power operation. Motors like these have been
ordered just in case it is found necessary to make this improve-
ment.
The Product Engineer intimately associated
with the fabrication, assembly, and mechanical trouble shooting
of the instruments will not be available for the duration
of the contract due to a sudden serious illness. Although the
instruments are essentially complete there is still a considerable
amount of work in perfecting their operation. This type of effort,
found commonly in prototype development, requires a talent for
suggesting and executing the small but necessary design modifica-
tions to make the unit operational. This responsibility will be
assigned to another product engineer, however, there will undoubt-
edly be some delay caused by this occurrence.
A problem has arisen in the tracking of the
film during transport. This we feel is due to the more compli-
cated path the film must travel. It is believed that more careful
alignment of the roller axes will remedy this.

Assuming that there is a relatively efficient
recovery of our manufacturing section from the sudden loss of the
cognizant product engineer, will be finished and made
ready for final inspection.

SUMMARY OF CORRESPONDENCE
Meetings 120 July 1966 between
Customer's technical representative).

Customer's representative had the following comments.
1) He found the noise of the nylon guide rollers ob-
jectionable during rapid film transport. This is the same type
of noise that he recently objected to in- 25X1
dicated that this would be investigated.
2) Customer's representative asked if the noise of
raising and lowering the platen could be reduced in- 25X1
dicated that this would be difficult to do.
3) Customer's representative would like to have pro-
tective covers over the platen raising solenoids similar to those

The writer) (visited the customer's facility
to investigate problems customer's representative was having
shaft and was not free to rotate in the disengaged position. This
was quickly remedied by removing the handwheel and cleaning the
shaft and bushing. A minor interference restricting the proper
operation of the shade was also corrected.
The left front handwheel was found to be sticking on its
In addition to these obvious problems, customer's rep-
resentative expressed concern over:
1) Noise level during operation due to lamp, motors,
and guide rollers.
2) Variation of film speed during slew, and in particu-
lar the slow slew speed when approaching the end of a 500 foot
spool of film.
A more detailed description of these problems is given
above under Problem Areas.
