JOB #552
The work in this reporting period has been to complete
design layouts and empha_ize purchase of long lead time items
throughout the instrument.
Optical configuration has been arranged that pro-
vides a practical optical and mechanical layout. This design
will allow all major subassemblies to be separately mounted
to a single plate so that servicing and adjustments are
simplified. In addition, the entire objective assembly optics
can be easily removed from the viewer for laboratory alignment.
Features, such as laser film marking, reticle, and objective
lenses can be added or deleted relatively easily. Design
layout should be completed in December.
Detailing is progressing and should be completed
in Deceiber. . No fundamental changes have been made, although
there have been minor alterations for clearance, adjustments
and machining.

2. EYEPIECE ASSENE Y (Contd.
Eyepiece support linkeage has been designed and are
awaiting final space requirements of cabinet and objective
assemblies. The design features a dead weight counterk;alance
and worm gear angular adjustments that should provide easy.
handling of eyepiece assembly.
Motion damping and locking are to be done by hydrau-
lic cylinders.
F1 MMME ASSEMBLY
Pattern and casting have been ordered and machining
and heat treat~3ent sources have been located. Because of the
many steps involved in processing this casting, close traffic
control will be exercised to minimize lost time. Delivery of
frame casting with completed machining will be in rrebruary,
representing at least one month delay in equipment delivery.
Design of x carriage is firm but Y carriage is held
up pending objective assembly design. Release for manufacture
of Y carriage is expected in December. Design work nearly
complete except for small changes for machining aids.
STAT
Although screw and its mounting configuration are
firm, order has been held up pending decision to use 2 1/2mm
or 5mm lead. screw drive will also be held up. Customer has
been advised by that delivery will be at least
three months as well.

6. SCAN DRIVE A ;SEMhLY
:;.can velocity aljust;-)ent circuits are being designed
so that :iaxi;,,ui1 velocity of It /second will always be attained
on one channel, regardless of nagnification setting of optics.
This feature is thou jht to simplify oscillator design and give
operator rapi. steering control. ;i bypass wilt be required,
however, to iregar~i zoom magnifier's factor on scan velocit/.
turfy of slo-syn motor's resonances has not been completed.
Two-,peed transrjissioo required for the scanning drive has
been ordered and is expected here in 'January.
7. LIGHT TABU / ND FIt..\l DRI1L
Final stages of design of light tartle are underway
with detailing and release for manufacture completed for
castings and other long lead time items. Cold cathode lamps
and vacuum plates will be released for manufacture early in
December. vacuu;:1 holddown system design should oe firm for
manufacture in December. Devising a practical means to retain
vacuum manifold is the principle problem being solved,
Film drives configuration is firm with many specially
designed parts in manufacture. r,alance of manufactured and
purchased parts will be released in December.
The followinc are conclusions made at a meeting with
customers personnel at i:ovember 19,
1963.
A. Maximum film temperature is now defined as ambient
+ 300 F or 13U? F maximum.
3. Design objective of equipment accuracy is .0001
inch/inch accumulating with travel.
C. scan drive velocity in either axes, either channel,
is to be auto3vatically reduced as magnification is
increased.
