List of Contractual Defects on Table Ser. No. 001
Defects
1. The table tilts by lifting the back of the unit and hinging
on the front. This creates a nutcracker effect at the hinge.
The tilt switch is located very close to the hinge, and it has ,
been determined that an operator could very easily suffer crushed
:fingers :while operating the switch..
2. The Y motion is locked when the table is tilted. This systeM
is actuated by a mercury 'switch. The adjustment required to pro-L
vide this locking feature just after tilting starts, and to
release the lock after it becomes horizontal, is quite touchy. ,
The prototype table is just as likely to be locked in the horizon-
tal position as unlocked. If this is relieved, the carriage may
start to roll forward when tilting occurs before locking takes-
place.
3. Using a gauge configured to show the maximum overall width of
a 6.6" film reel, it was found that interferences exist at all.
reel stations. Further checks; on the production models available
at that time showed that 23 of 24 stations checked are too narroW
and will not accept the 6.822 inch dimension specified.
.The cable which connects the focus mechanism to the power
supply and electronics at the back of the table prevents the
focus mechanism from realizing full travel to the back of the
viewing surface.
5. Markers are provided on the table to aid in placing the motors
and idlers for various film configurations. The motors have i
matching markers on one side. However, the motors must be used in,
such a way that the side not containing the marker is in view.
Consequently, markers must be placed on both sides.
6. The MLT is made in two parts, an elevating stand and the light
table proper. If the light table is not put on the stand at the
right place, or if it shifts while being transported, the lower

switch housing. The lower cover will not open when the table
is tilted.
7. The mechanism which takes up the dead loop at the center of
the table employs cable guides which hold the actuating
mechanism in its track. These cable guides have profiles whiCh
prevent the looping mechanism -.Cram reversing direction at one
point in its travel.
8. The lower cover latches are. very difficult to operate, due ?
to their placement and design. .
9. The illumination sources are not equal within 100 fiat
maximum. The left measured 3225 fL max and the right 3010 fL max.
The change in output of one side when the othar is turned
completely down or up should not exceed 100 fL, This change was
measured to be 150 fL on the left side and 165 fL on the right
side.
10. The screws holding, the pod in the optics mount do not
provide adequate force to prevent unwanted motion
11. There have been instances of evidence of poor quality con-
trol. a) The bearing track on the left side was not fastened
tightly. b) The plastic protector covers on the Y chain drives
dragged the chain and drive elements. c) The power cord reel
fell off of the unit. d) The tilt lock mercury switch was not
set properly.

enclosed to prevent inadvertent access by the
operator,
Para. - A manual oriage furnished with i
tilting stand shall be proVided with an optional
fail-safe override to prevent uncontrolled MetiOn T
in the I direction when the table is tilted. To
move the carriage in the Y direction with the tah:
horizontal, it shall be neCessary only to rel
the I friction lock. In a. tilted Position, a laJ,
safe interlock shall be activated preventing Y
translation unless the interlock is purPosely
defeated.
Para. 2 - The table shall accommodate spools .
ranging up to and including the Size of spool
specified in Military Standard MS26565-22 loaded
to Capacity with filM.
Para. 3.4.1.2 - With any of the microstereoscoren
fixed in the mount, and using the .center of the
Scope as a reference; translation in the Y direo-6_
shall be adequate to cover the full 15" depth of
the glass viewing surface.1
Para. 3.3.1.2 - A visual reference scale and indi:,Y
ing device, with positive de-tents shall be providar
to allow accurate poSitioning of the brackets to
hold the various width spools and assure accurate
tracking across the glass viewing surfaces of the
film parallel to: the longitudinal axis of the lic.1!
table and to each other.

cover is prevented from dropping by the tilt and elevating ,
switch housing. The lower cover will not open when the table
is tilted.
7. The_mechanism which takes up the dead loop at the center of
the table employs cable guides which hold the, actuating
mechanism in its track. These cable guides have profiles whiCh
prevent the looping mechanism from reversing direction at One ?
point in its travel.
8. The lower cover latches are very difficult to operate,- due
to their placement and design. .
9. The illumination sources are not equal within 100 fL at
maximum. The left measured 3225 fL max and the right 3010 fL max.
The change in output of one side when the other .is turned
completely down or up should not eXceed 100 fL. This change was
measured to be 150 fL on the left side and 165 fL on the right
side.
10. The screws holding the pod in the optics mount do not
provide adequate force to prevent unwanted motion.
11. There have been instances of evidence of poor quality con-
trol. a) The bearing track on the left side was not fastened
tightly. b) The plastic protector covers on the Y chain drives
dragged the chain and drive elements. c) The power cord reel
fell off of the.unit. d) The tilt lock mercury switch was not
set properly.

Para. 2 - The table shall include a simple film
looping mechanism which shall allow forming a locT
of film below the:table-in order that separated
frames, on the same roll of film, may be arranged.

illumination sources shall not differ by more th:n
100 foot lambertsat'the time of this measurement,
With. one of the two sources set at,. maximum or
