MEETINGS
Scheduled percentage of completion 89%
Actual percentage this date 89%
The Contracting Officer's Technical Representative
held a review meeting at therplant.
During this meeting the schedule and te'chnical
status of the Stereocomparator program were discussed.
A method of performing preventiive maintenance
and routine calibration tests, for the Stereocomparator, was
suggested and discussed. It is proposed to use diagnostic
computer programs in connection with previously standardized
phtography. This approach to the problem of minimizing service
time and downtime appears quite feasible, however no suitable
diagnostic computer programs presently exist.
The minutes of the meeting appear in Appendix II.

The lasers have been returned to
ment of the plasma tubes by the manufacturer
It was found that due to cable capacitaince, the
10, 000 volt starting potential for the units was not being trans-
mitted by the cables.
A circuit analysis of this system was performed
and it was found that the requirements for capacitance per unit
length of the high voltage lead in the laser connecting cables
were extremely stringent.
The laser power supplies have therefore been
moved adjacent to the lasers, to brackets at the rear of each
measuring engine. The system performance is expected to be
fully satisfactory in this new location.
Electrical connectors have been ordered for the
recabling necessary in connection with this change.

Systematic testing of the digital logic interface is
essentially complete. The computer link to the customer's external
equipment is being thoroughly checked out in order to remove some
extraneous noise in the digital logic associated with this system.
The work performed on the IBM 526 Card Punch has been
found thus far to be satisfactory.
The work remaining on this task Consists mainly of final
debugging and testing of the stage drives and measuring systems.
When the final stage drive loop compensation has been determined, the
Stereocomparator will be ready for installation of the optical assemblies
and also for checkout with the computer tracking program.

JOB 342
Contracting Officer's Technical Representative
Purpose: Discussion of progress on the Ultra High Precision
Stereocomparator
During the meeting several topics were discussed.
? Various methods for transporting the optical assembly from Paris
to the facility were suggested.
The Operating Instructions Manual outline, and a portion
of the draft were reviewed by the Contracting Officer's Technical
Representative. In addition, he discussed the Preventive
Maintenance Service Manual, and the possibility of providing two
diagnostic computer programs.
The results of the meeting were:
1. That military air transport might be the most feasible
method for transporting the optical system to Berkeley
from Paris.
2. The Contracting Officer's Technical Representative
agreed with the general tone of the Operating
Instructions Manual after reviewing the proposed
outline and portions of the draft. He also agreed
with
STAT
STAT
suggestion that specific STAT
operations explained in the Manual be condensed
and printed separately on easy-reference plastic
laminate sheets.
3. The suggested scope and form of the Preventive
Maintenance Service Manual also seemed acceptable
to those present.

2. One of the 4X ratio zoom systems was found to be
mechanically inadequate. The entire guide system for
it is being rebuilt. The other 4X ratio zoom system was
satisfactory.,
3 The air cooling and the electrical insulation for the lamp
mountings in both main lamphouses were found to be
inadequate, found that the present system for STAT
air cooling does not cool the condensers sufficiently,
while it over-cools the lamps.
A quartz plate is being inserted to separate the condenser
and lamp. Baffles will also be installed to limit the air
flow to the lamp.
The present mounting insulation for the lamps is not
adequate to withstand the starting voltage and must be
redesigned.
4. Certain cams for operating the microsw itches in the main
illumination system main casting assembly, must be

are installed and appear operationally satisfactory.
The objectives have been installed but not the air

requires changing cams for the microswitch "dual"

The left system is less complete. As of this visit, the

The other is still exhibiting image wander, and is in the

including the light filter discs, the "red" filter switch
system, and the condenser. The electrical parts are

The detailed test results report is dated December 5, 1969,
A brief summary follows.
In the test the frame containing the entire
objective system was mounted in the optical bridge.
The moving parts of the optical system were clamped in
special tooling which prevented either rotational or
focusing movement, as follows: fiber washers were
arranged so the upper peripheral thrust bearings were
separated by 0.27mm, and the system clamped in this
raised position, which prevented rotation. Focusing
movement was prevented by 2 bolts screwed into the nose
sections of the objective lenses. The bolts were supported
by tooling from the
STAT

casting and were mounted in their STAT
support plate by fiber washers, which are quite hard
material.
The
optical bridge containing the objective system was
then placed in an inner shipping crate and blocked in position
with wood blocks covered with 5mm thick felt. This inner
crate was encased in air bags (inflated to 100gms/cm2, or
1.422 psi), and the whole placed in an outer shipping crate.
The system was shipped by truck 25km outside of Paris over
a badly surfaced road. Accelerometers set at 5 and lOg with

time minimum sensing at 60cps were placed inside and
outside the outer shipping crate. Neither accelerometer
showed a reading after transit. The maximum truck speed
was estimated at 40km/hr.
The test results indicated that this manner of packing and
shipping caused a rotational deviation of 2 seconds of
arc, or the equivalent of 3mm backlash. Prior to shipping
the image wander was 1 second of arc. Other charac-
teristics were unaffected.
In addition, the system was rechecked by passing an
image from the objectives through the 10X zoom system
and the deviation was found to be approximately ? 0.25p.m,
a value within tolerance.

Additional data on backlash are being determined.
has suggested that it might be prudent for
to determine if this method of clamping, used several
times (as it must be in actuality), will increase the back-
lash each time.
16. Review of the main illumination filter disk system shows
that the 24 volt printed circuit motors are underloaded.
The electric system rotates the filters 360? from stop to
stop in 3 seconds at 2.6v and with a current of less than
1.0 amp starting and 0.6 amp running.
Under these conditions the tachometer has an output of
approximately 2.0v, and is operating at the same RPM
as the motor which approximates 300 RPM maximum.
has determined that the 24v servo system will operate
properly under these conditions.
It was also found that the MS plug called for in Drawing
C8534A for the motor could not be used because of the
space available. On their own,

The Representative requested that all the extra pins

has encountered technical difficulties with the STAT
microswitch mounting on the main anamorph. The pre-
limit switches present no difficulties, and the first limit
can be set exactly at 2:1, but the second limit cannot be
set 2% further on because the potentiometer drive quadrant
will hit the drive shaft on one of the prism mounts.
will either have to demount the quadrant and
cut a notch in it, or reduce the range of the anamorph

notch because the re-work may throw the system out of

time.
