PROGRESS REPORT - 552 and 552A
for January 1967
552 #101
Trip was made 26 January to prepare laser equipment
for return shipment to factory and replace transistors in reg-
ulator circuits. Laser power supplies and heads will be mod-
ified and returned to customer early in February.
552A #102
During trip made 26 January, inspection of this system
was made. The following was observed:
a) Left channel would move + and -X and -Y only. Joy-
stick output OK and direction relays were OK. Found a circuit
card in "Slo-Syn" translator faulty and when replaced, normal oper-
ation was seen.
b) Right channel barely move + or -Y axis.
Joystick output and direction relays OK. Time allotment
ran out preventing further study of right channel.
An estimate to correct anticipated problems above, has been
prepared and forwarded to customer.
552A #103
A trip was made January 19-20 to replace repaired joy-
stick potentiometer. Joystick was refurbished together with
repair of problems with left objective turret, right zoom mag-
nifier, right dot reticle, widening scanning limits, reduction
of film scratching with rear holddown and manufacture of more
comfortable gear selector switch operator. At conclusion of the
visit, equipment was to begin the two week trial period for acceptance.
552A #104
Image Alternator and Power Assist Film Drive are in-

stalled and operating with a few "bugs" remaining in the film
drive circuitry. Problems plaguing scanning drive electronics have
debugged to allow completion in early February. Principal difficulty
was to discover cause for damaged joystick potentiometers. Induced
transients from adjacent circuits appear to be the culprit and have now
been effectively reduced for safe operation of scanning systen.
With the favorable scanning drive situation completion
in February is assured. Final timing on optics and other sub-systems
can now proceed for completion.

PROGRESS REPORT 552, 552A FOR DECEMBER 1966
The following work has been done on these systems:
552 #101
Mercury displacement relays to interrupt laser high
voltage has been received and is in a test circuit to check its
performance. These relays will require modification of laser power
supplies for their mounting.
Power transistors to replace marginally rated units in
laser reticle drive circuit have been received and are ready to be
installed in system.
To install relays we are making plans to return laser
power supplies to factory. This will assure minimum interuption
of customers equipment area. Transistor replacement and laser checkout
at customers shop will follow completion of relay rework at factory.
552A #103
Service call to search out repeated failure in scanning
drive was made early in December. An open joystick potentiometer
proved to be the trouble and was sent promptly to its manufacturer
for repair. Potentiometer is expected to be installed in January.
At that time joystick mechanism will be thoroughly adjusted and checked
out.
552A #104
Installation work on 'Image Alternator and Power Assist
Film Drive is advancing well. Image Alternator is wired and will
be checked out in January. Film Drive modification has wiring and
mechanical assembly about 70% completed. Work on film drive is
expected to be completed in January.

A continuing problem in scanning drive has prevented
completion of its adjustment. After damaging (2) joystick
potentiometers due to excessive output currents, an intensive
search for the circuit fault is being made to prevent further dam-
age. Resolving this difficulty will determine when system is
ready for shipment, hopefully by the end of January.

PROGRESS REPORT 552, 552A FOR OCTOBER 1966
The following has been the work on these systems:
552 #101
No action has been taken on proposed methods for measure-
ment improvement.
552A #102
No action has been taken on proposed attack on scanning
drive problem. Other work to check over optics remains to be done
in a service cell.
552A #103
Customer has informed us of repeated failures in scanning
drive with relation to length of "on" time where acceptable operation
after 3 to 4 hours of "warm up". Other times instrument required
no such preparation for use. A service call will be made early in
December to trace this problem out.
552P #104
Work has advanced on image alternator, film drive and
system adjustment and debugging. Image alternator is moored ar}d
electrically operable. Wires for power input have to be installed
into existing harness and transformer supplying power has to.be
installed. Detailing of film drive components has been nearly com-
pleted with many parts already for assembly. Electrical harness
conversion is underway to bring power into film drive motor amplif-
iers and to writing. The electrical work will continue during.
December as well as other system electrical work in scanning drive.
Optical adjustments should be completed in December leaving film
drive modification and system debugging left for late December and
January.
