Fabrication of parts and procurement is complete with
exception of a few items associated with the electronics. These
delinquent items are not affecting the assembly however.
Mechanical assembly of the table is 25% complete and of
the elevating table 50P/. complete,
PROBLEM AREAS
I
Tracking Light Sources
Difficulty has been encountered in the, design
..of the high intensity tracking light sources in obtaining full,
coverage over the viewing area. The problem is with the design of
the mechanical linkage which is used to position and hold the master
magnets. Last month is was reported that interferences exist when
the magnets are toward the rear (away from the operator) of the
viewing format; it was also suggested that this may not be a serious
limitation. However, since that writing, it has been established
by the customers representative that the rear potion of the viewing
format is of great importance becuaae of the more favorable position
of the microscope eyepieces with'reict to the operator when the
rhombiods are positioned toward the'tear. Consequently, the des,gti
has been changed so that the rear part of the format is favored.
This, however, only shifts the problem area from the rear to the
front of the format. Fabrication of the new design is proceeding

with the realization that there may be an area in the front of the
format where the high intensity sources may not be useable.
Platen Raring Mechanism
Initial testa of the platen raising mechanism
showed that friction and alignment tolerances resulted in marginal
performance. The design was immediately changed and the modifica-
tion is currently being incorporated. The change does not alter
the basic actuating device (a linear induction motor- "Polynoid")
but only requires modification of the actuating linkages.
PROJECTED1 WORK FOR NO DER
Mechanical assembly will be 80% complete. Electrical
assembly will be 50% complete.
