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.
