April 1966
11 May 1966
Mechanical and electrical assembly is com-
pleted and equipment is ready for delivery.
A center shade to mask out the illuminated
strip between adjacent films has been installed, servo performance
improved, audible noise reduced, solenoid covers installed and
other problems existing at the customer's visit on April 11 have
been resolved.
Fabrication of parts is completed and mechanical
assembly 50'/ finished.
Fabrication of parts 95% complete with the
few parts required for the high intensity light source and the
main casting being the major unfinished areas. Assembly of main
gear box is approximately 20% complete.

MUM ,M, AREAS
In an attempt to reduce the 60 cycle hum
emanating from the light source, the lamp was disassembled and
a silicone rubber compound was placed between the tube grid and
the supporting pan. This was effective in reducing the audibile
noise, but required the raising of the tube grid about 1/16 of an
inch closer to the diffusor. Subsequent measurements of light
intensity variation revealed that the uniformity had been degraded
to a 15% variation over the 11 x 18 inch format.
The fabrication of this unit has been held up
considerably due to delays in obtaining the main casting and pro-
blems encountered in the sub-contract machining operations. It
is estimated that the [::nechanical assembly will be,completed
on 5/18/66; electrical completed 5/25/66, and equipment ready for
inspection the week of June 6, and i about two weeks later.
