Section I
INTRODUCTION
This proposal includes revisions and changes made in the Variable
Width Film Reader specifications up to 5 April 1963. These changes
relate to the overall size of the machine, the illumination source,
and the film transport mechanism. Drawings F145A (figure 1) and
B931A (figure 2) are changed to show the new requirements. In other
major features - such as film measurement, rotation, lens selection
it remains the same as described in the NRI proposal dated
15 February 1963.
The instrument described in the following sections is an operating
engineering prototype, but throughout its design and construction
every effort will be made to inCiude the refinements necessary to a
production model.

INTRODUCTION
This technical proposal outlines a system which will have the operating
features specified in "Design Requirements for a Variable Film Width
Reader" and revisions. Image rotation, high resolution r-Ulumination and
high-speed film transport are the major design problems.
STATOTHR
Preliminary study by ^ has resulted in an outline proposal for a system
to meet all the operational specifications for the Variable Width Film
Reader. In this discussion, we will present design and support data for
each necessary subsystem, along with the performance that can be
expected from optimized components.
The equipment configuration shown in the specification drawing will be
followed, in general, in the layout of the final measuring machine. An
overall height of 64" and length of 108" should be sufficient to contain
all necessary components. The width at the front of the machine will not
exceed 34 inches o As will be explained, the design process must begin
with the requirement for high intensity illumination, which demands a

liquid cooling system. This in turn affects the film drive design,
and the complete film transport dictates characteristics of the
rotating mechanism

1. FILM COOLING
The major problem in the specification is the intense illumination
required on the screen. For metered film drive, the film can not be
in contact with a glass platen. Government sponsor--d research
is now in progress on a liquid Freon film gate, in which the film is
suspended between horizontal planes of lendnar flow in a stream of
liquid Freon, (see figure 1) . The Freon flows between parallel
glass plates, which form a platen containing the film and holding it
in the viewing plane. It absorbs heat from the illuminated film area
and re-circulates through a heat exchanger, where the Freon is cooled.
Figure 2 shows the supply and take-up reels both suspended over the
cooling fluid, ds they will be during measurement. Freon 113 will be
used as the cooling liquid. It will be filtered as it recircul_:rtes, to
remove any dust which enters from the film. A pressure differential
across the :..late of approximately S psi is expected to produce.
appropriate flow rates. A spacing between the glass plates and the
film of . 001" to , 00 5" seems to be stable for a range of flow rates.

In the proposed Screening Projector, the major purpose of the
"liquid gate" approach is to cool the film by a process of
conduction (film to fluid) and convection (heated fluid is
pumped from the platen to a heat exchanger) . A mixture of
nine parts of toluene and one part of Freori-113 liquid is
recommended; this mixture is colorless, has low toxicity, is
less expensive than Freon-i 13 liquid alone, and has an index
of refraction of 1 .50. Therefore scratches and other marks on
either side of the film itself are not visible in the projected
image. Eastman Kodak has established that there are no
dimensional changes to their film (all types) as a result of
being exposed to a liquid Freon cooling system.

2. FILM TRANSPORT
2.1 Measurement
Distances on the film are to be measured to a least count
of 10 microns over a range of 30 inches along the film, and up
to 9 1/2 inches across the film. The Instrument will accommodate
film widths from 70mm to 9 1/2 inches. Measurement accuracy
will be as specified; that is:
Accuracy of Z25 microns over any area on the film
70 mm square
Accuracy of Zlmm over an area on the film of
9 1/2" x 30" .
Such a measurement of film distances implies a driving and
metering roller which maintains tension on the film In tho
viewing region, and also a transverse movement of film across
its width. The first is described below under "Film Drive" and
the second in paragraph 3. under "Stage and Rotation" .
2.2 Film Drive

may be from 70mm to 9 1/2" wide. Power for driving the two
reels is supplied by their respective servo motors and ampli-
fiers, but film speed is controlled by a capstan drive in the
pressurized side of the film chamber, The film is driven by
the pressure differential capstan shown in figure 3, and
metered by an Optisyn encoder which gives film travel in
increments of 10 microns over a range of 30" . Tension
sensing rollers supply feedback signals to the servo amplifiers
which drive the film reels. The film speed control for measure-
ment is interlocked with magnification selection (see Section 6
for more detail).

A second one-axis Joystick will be used for film rewind and
fast advance. Maximum deflection of this "film slew" joystick
will produce a minimum speed of 250 ft/rr,in. It will override
the "measurement" joystick. At this time insufficient data is

available to establish a final design; however it appears
that for protection of film and film platens, the fast slew
..r~:i rewind should take pluo_, with Freon running through the
:,ate .is it does during viewincT and measurement.
Connected to the driving shaft (see figure 2) are the < encoder,
the or_,ssur differential capstan (described in more detail
b^low), the speed control servo motor, a clutch-brak-, and a
selsyn. Inputs to the servo smplifier may conic eithc_r from one
ootentiomete?r on the joystick or from the primary wining of
the receiver selsyn, which senses position of the handwheal
(see figure 4). When the speed control joystick is off zero,
the clutch disengages the selsyn from the drive shaft. When
the joystick is at zero, the clutch engages the secondary of
the selsyn to the drive shaft.
Output of the servo amplifier is a DC signal, controlling
velocity of the Model 368 printed circuit motor. This motor
turns the capstan and encoder, giving the :{ coordinate for
film measurement. The capstan circumference is 163,840
microns. The encoder is a Model 35 Optisyn with 16,334
counts per turn, each count representing 10 microns.

Because of the solvent properties of Freon, all electrical
components are in the room atmosphere, separated from the
Freon by seals o The pressure differential capstan which
supplies film speed control consists of a slotted roller moving
over a stationary cylinder, also filled with fluid at lower
pressure. Since the Freon hydrostatic pressure in the chamber
is approximately 8 psig, the differential pressure between this
and atmosphere holds the film tightly against the roller as it
turns. By blocking off different regions of the low pressure
side, the same roller can be adjusted for the various film
sizes. See figure 3 for capstan details.
The film reel drive motors are Model 488 DC printed circuit
motors driven by servo amplifiers. Input signals for these
amplifiers come from tension sensing rollers on either side
of the platen, and maintain a constant film tension across
the platen region.
Liquid Freon 113 recirculates from the atmospheric side
through a heat exchanger to the high pressure chamber. The
pressure chamber and the configuration of platen and film

rollers will be designed to sustain constant laminar flow
through the platen region, Spacing between film and the
glass plates must be approximately .004 inch, according
to information currently available.
Both Freon and air are pressurized in the right-hand side of
the chamber, A strip of 70mm leader material is permanently
attached to the take-up reel, and the " supply" film will be
taped to the leader end, on loading, so that the operator need
not thread film through the platen each time o An "air knife"
at the supply side, removes liquid Freon so that the reel will
be dry when removed a
When the Freon pump is turned off, the liquid is removed from
the platen region into a reservoir so that all guide rollers are
accessible. To change film width, different size rollers and
adapters are placed on ec-wh spindle. The center of the film
will always be on the same line, no matter what width film is
used, so that the center of rotation always lies in the film
frame, Interlocks and "end-of-film" detectors will be
included to prevent the operator from pulling the end of the
film off the supply reel.

3. STAGE AND ROTATION
The image on the display screen should be rotatable 180? about
its normal position so that Imagery can be oriented In the most
readable direction for the operator, However, C and Y measurement
must be referred to film coordinates; therefore a crosswire measure-
ment on the screen is not appropriate, since it involves encoding
rotation and adding this data to the screen measurements in order
to find true film positions. Therefore we must rotate the film itself,
and with it the measuring system A simple and practical method of
rotating the film, film drive, and measuring devices is based on
development work with air bearing granite engines.
Assume that the film reels, platen, motor, vacuum rollers and
