SUBJECT: Briefing Print Enlarger Deficiencies
1. A meeting was held on 7 September 1967 at NPIC for the purpose
of discussing the operational deficiencies of the Briefing Print En-
larger (BPE) encountered b PSD since installation of the equipment
on 26 June 1967A I
2. The major problem, according tol is the fluid gate
design, which allows bubbles to remain in the projection path. Other
problems discussed was the permanent condensor lens mountings which
prevents the lenses from being thoroughly cleaned, the coordinate
counter should be in millimeters instead of centimeters, and a cut-
off is desired on the vacuum easel to permit an operator to more
accurately position the print paper.
representatives,the operational problems the following decisions were
reached:
3. After operating the Enlarger for a time, to show the
a. Qwill provide a larger knob on the lamphouse to
move the gate into position more slowly.
b. 0 will look into the fluid gate (bubble) problem
by devising some method of holding the film equidistant
from the gate glass when injecting fluid, by trying dif-
ferent nozzle configurations, and trying various gate
fluids. The breadboard equipment, still at =will be
used for this investigation insofar as possible. It may
be necessary to use the DIA machine for a week or two if
the breadboard will not suffice. Verbal permission has
been granted by DIAAP-10 to hold up delivery on their
Enlarger if necessary.

c. The redesign of the condensor lens and gate glass
was held-up pending further field use. However, it was felt
that any change from the solid permanent mounting would de-
grade the quality of the product.
4. PAR's 247 and 248 for BPE spare parts and High Magnification
Lenses were also discussed with regard to shortening delivery time.
DIA was queried as to whether they wanted to go ahead with their High
Magnification Lenses before the prototype was completed. They said
to go ahead with the order under existing funds.
5. 0 will advise us of any design changes required as a result
of the above investigations, with the estimated time and costs associated.
