(OPERATING MANUAL
I GENERAL DESCRIPTION
STAT
STAT
STAT
is a film viewing table of advanced design. It in-
corporates many features which make the viewing and interpretation of
aerial film or other transparent fil-ns faster, more efficiently, and
less fatiguing to the operator. STAT
STAT
consists basically of a transilluminated table mounted
on a tilting base with provisions for mounting and spooling of film a-
cross the top. The table will accept standard spools of 9 1/2,
5 inch or 70mm =ilm with lengths up to 500 feet. In the case'of the 5
inch and 70mm films, two films may be viewed at the same time. The tilt-
ing base permits the viewing surface to be positioned anywhere from
horizontal to 75 degrees. The instrument may also be swivelled on the
base so that the axis of tilt is changed. When the equipment is used
tilted about the short axis, a third handwheel is available on the back
(now the left side when facing the format) for convenient control of the
rear film.
Film transport is accomplished in one of a number of modes
through a unique electro-mechanical drive system which allows one hand-
wheel to be used for transporting film in both directions. A power
assisted mode of operation is available which relieves the operator of
most of the physical burden of transporting film. A fully automatic
mode in which the handwheels are not used is also available. In this
mode, the operator controls film motion by potentiometers.

STAT
Spooling of film with either the emulsion in or out is ac-
complished by spool drive reversing gear boxes in each drive spindle
head. This allows handwheel motion to control the direction of film
travel regardless of how the film is being spooled (i.e., emulsion in
or out).
A coupling device is included to permit both film drives to
be linked together and controlled from any one of the three handwheels.
Both films may be driven in the same direction, or in opposite direc-
tions by the same control.
II DESCRIPTION OF CONTROLS
(Refer to Figure 1)
On Base
1) Power ON-OFF Switch - Controls all power coming into
equipment.
2) Tilt Control - A momentary contact center OFF switch
which controls direction of tilt. '-!P increases tilt; DOWN decreases
tilt.
3) Fuse - All electrical power passes through this fuse. It
is a type 3AGX 5 ampere (slo-blow).
4) Swivel Lock - A spring loaded plunger which locks the
light table on base in either of two positions. Pull down to release.
On Front Panel
5) Pilot Light - Illuminated whenever main power switch is
6) Brightness Control - Controls general format illumination
brightness. Counterclockwise rotation increases brightness. Switch

actuation at limit of CCW travel increases brightness by removing com-
pletely dimming control from circuit.

7 & 3) Light Shades - 7 and are thumb wheels, mechanically.
P
connected to the front and rear shades respectively. Each shade may be
extended across the format to slightly beyond the middle. Control for
the center shade (17) is located at the rear right corner of the table
and is described later.
9 & 10) Filin SPEED Controls - 9 and 10 are the controls for
mechanically changing the gear ratio between the handwl-eels and the film,
spools. In the "low" position the ratio is 1:1 and in the "high" posi-
tion it is 1:2.5 (spool faster). Control 9 is for the front film, and
10 for the rear. In the mid or neutral position the handwheel drive is
disconnected from the spool drive.
11) DRIVE COUPLING Control Lever - the DRIVE COUPLING con-
trol lever mechanically couples the film drive systems so that any one
of the three handwheels may be used to drive both films. It has three
positions; in the center or "independent" position (which is not labelled,;
the film drives are independent, in the SAME position the films transport
in the same direction, and in the OPPOSITE position the films are coupled,
to transport in opposite directions.
12 & 13) SLEW Controls - 12 and 13 are the automatic slew
controls for the front and rear films respectively. These are operative
only when all three Landwheels are in the disengaged positions (pulled
out). Their direction and angle of rotation from the center position
determines the direction and speed of film transport.
14) POWER ASSIST Switch: - It. the "on" (up) position, this
switch activates the power assisting motors and clutches. It must be in
the up position. when operating in either the power assisted mode or in
the fully automatic mode. In the down position there is only a direct
mechanical connection between the film drive system and the corresponding
handwheel.

STAT
15) LOADI:h3 Switch - The loading switch deactivates (in up
position) the film tensioning rollers and reduces the friction on the
mechanical brakes. This is provided primarily for the purpose of load-
ing film.
16) CONTROL SELECTOY. Switch.- This switch is always left in
the LEFT position except when the Coupling Control (11) is in either
the SAME or OPPOSITE positions. With the equipment in one of these two
coupled modes the Control Selector Switch selects which handwheel (or
slew control knob) is to he effective in transporting film. Thus, in
the coupled mode when this switch is in the LEFT position the left
(front film) handwheel is controlling both films and when in the RIGHT
position the right (or rear film) handwheel is used to control both
films. When in the RIGHT position, however, which of the rear film
handwheels in operation depends on position of the Alternate Handwheel
switch (13) which is described later.
It should be noted that this switch is of concern only
when operating in the power-assisted or fully automatic modes of film
transport. With the POWER ASSIST (14) switch off (dowr:)'the film drives
are only mechanically coupled to the handwheels, thus any handwheel is
operative in the coupled mode regardless of the position of this switch.
On t e Light Table
17) Center Shade Control - The center shade is positioned
by rotating the control crank on the rear left side of the light table.
This crank controls the position of the opaque section of a Mylar belt
that travels down the center of the format. The opaque section is po-
sitioned over the format when two films are being viewed and the clear
section when a single large film is being used.
NOTE: There are stops in the position of the belt. Since
there is a friction drive, no damage can be done, when the stop is
encountered.

STAT
18) Alternate Handwheel Switch - Located on the light table
casting next to the rear left (when facing front panel) handwheel, this
switch actuates this handwheel when in th up position. It is intended
to be used only when the instrument is tilted up about its short axis
and is being operated from the end. Actuation (up position) of this
switch in effect transfers control of the rear film drive from the front
right handwheel to the left rear handwheel.
19, 20 & 21) Handwheel Clutch and Interlocks - Each handwheel
has two axial positions on its shaft. In the "in" (handwheel pushed in
toward the casting) or engaged position, the handwheel is mechanically
coupled to its respective film drive. The engaged position also causes
the handwheel interlock switch to?actuate which prevents the film from
being transported by using the slew controls. With the handwheel in the
"out" or disengaged position, it is decoupled from the film drive and is
free to rotate on the shaft. In this position, the handwheel interlock
switch is deactivated, which (when all three are deactivated) allows the
film to be transported using the slew control knobs, while the handwheels
remain stationary. This is primarily a safety feature.
NOTE: All handwheels must be in the disengaged position in
order to operate in the fully automatic slew mode.
On the r i.lm Drive Gear Boxes
22) ROTATIO1` Controls - On each of the four film drive gear
boxes there is a ROTATION control. This controls the direction of
rotation of the film spool relative to that of its corresponding hand-
wheel. Thus, when the lever is set at SAME, rotation of the handwheel
rotates the spool in the same direction as the handwheel and when in
REVERSE opposite directions occur. This feature is included to allow
any combination of emulsion up or down viewing with emulsion in or out
spooling.

23) Drive Spindle Lock - On each,. of the four driving spindles
there is a locking device which locks the spindle in one of two positions.
For loading film the spindle center button is depressed and the spindle
withdrawn until it locks in its "o-.it" position. When the film is loaded,
the button is depressed and the spindle driving dog allowed to enter the
film spool until the in" detent position is reached where upon the
button pops out and the spindle is prevented from moving axially.
24) Drive Gear Box Position Lock - On each of the four drive
gear boxes there is a thu-,lbscrew type locking device which holds the
gear box in the proper position for the different film spool sizes. De-
tents are provided on the guide rods for the most common film widths of
9 1/2 inch, 5 inch and 70mm. Other film widths may be used by disre-
garding the position of t:-e detents. In these other cases, care should
be exercised to prevent excessive tightening of the thumbscrews since
they could be clamping outside of the detent area.
25) Center Support Lock - The center spool supports located
at either end of the table have thumbscrew type locks. Detented position..
are provided on the guide rod for the common film spool widths, although
other spool widths may be accommodated by clamping outside the detents.
Care should be exercised in such cases not to excessively tighten the
thumbscrews.
The unit may be carried by two people by lifting on the
underside of the light table. Do not lift by the handwheels, gear box
guide rods, or film rollers. The unit is most easily lifted when the
viewing surface is h-,orizontal. when in the rear vertical position
(tilted about short axis) the unit may be carried by two people lifting
on the underside of the tilting base,.

STAT
is designed to be used on a table of normal or
lower height. It should be positioned so that the edge
of the base
plate comes right to the front edge of the supporting surface. This
position allows handw'-.eels to clear table top when instrument is tilted
about the long axis to 45 degrees. Do not , t;le front edge of Jhe
base plate eztend over t:-:e edge Qf, t_e table otherwise the stability of
the instrument may be jeopardized when it is erected to its near-vertical
position.
Ap121yir.1 Power
All power is obtained from the conventional 115 volt, 60
cps single phase supply. The instrument is supplied with a power cord
and common three wire grounded plug. The ground wire is connected to
the frame of the instrument to prevent accidental shocks in the event
of an electrical malfunction.
The equipment is fused at 5 amperes with a standard 3AGX
5 ampere slo-blow buss fuse (3).
Plug equiaaent into properly wired outlet and set SLEW
control knob pointers (12 and 13) to tueir reference marks. Turn on
Power Switch (1), pilot light (5) should glow indicating power is being
supplied to the equipment. No warmup time is required before operation.
B) Orientation of Format
The light table is mounted on a base which provides two de-
grees of freedor.i in the orientation of the viewing format. The base
tilts forward and may be adjusted at any angle from horizontal to 75
degrees although when ti,e table is in one position (long axis parallel
to edge of support table) the angle of tilt should be limited to approxi-
mately 45 degrees because of interference between handwheels and table.

The light table may also be pivoted through 90 degrees on the
base assembly to allow the short dimension to be parallel to the edge of
the table. The Swivel Lock (4) provides a positive lock in either of
these two positions. In addition, there are mechanical stops to prevent
the light table from grossly exceeding its swivel limits.
To adjust the table for viewing, withdraw spring loaded Swivel
Lock (4) pin by pulling down and swivel table to desired viewing orien-
tation. Make sure Swivel Lock snaps into the locked position. Turn on
power (1) :end actuate Tilt Control (2) in direction of desired tilt.
This is a spring centered switch and must be held in position for as
long as one wishes the tilt angle to increase (or decrease). Releasing
the switch stops the tilt motor and locks the tilt mechanism. No ad-
ditional supports or stays are necessary, nor are any provided.
The tilting mechanism is capable of providing up to 75 degrees
of tilt with both mechanical stops and electrical limit switches pre-
venting overtravel. However, the operator should be aware of the
following limitations:
