1. On 20-21 June 1967, the in-plant chank-out of the n-ratntyna Brief g
Print Enlarger (BPE) was made at thel
25X1
25X1
2. The first day (1/2 day) was spent in familiarizing the NPIC_.personnel
with the operation of the instrument. The second day was entirely devoted to
instrument performance, using the BPE Preliminary Specification 469-333B, dated
15 March 1967, as a guideline for anticipated results. Check-out was made
primarily with the "A", "C" and "F" lenses due to the limited time available.
All parameters of the test specification were met or exceeded with the excep-
tion of the 550 1/mm called for with the "F" lens at 62.5X magnification and
80" OAC. The best resolution obtainable in the testing was a positive 522
1/mix. This, however, was felt to be the result of a defective target in the
original material and n t the::. lens set. The film transport problem encountered
in the late stages of testing appears to be solved. Both 70mm and. 9 1/2" 25X1
material was transported at all speed's with no creeping, back-lash, etc. The
fluid gate system operates satisfactorily, although it is felt that operator
experience will be required to assure optimum operation. Several instances
occurred when the gate was closed too quickly or too slowly and trapped air
between the glass plates and the film.
3. As a result of the successful check-out the prototype BPE will be
crated and delivered to NP on 26 June 1967 for installation and acceptance.
An installation team from will be on hand through 30 June 1967 for this
effort.
4. Additional funding above the estimated total of will prob-
ably be requested by far co letion of the prototype BPE. This amount is
estimated to be around

5. The f n items concerning the RT-12 and T-24, processors were
disucssed wit
a. RT-12 -- A cost estimate was requested for 232 stain"
.ssa:stgel studs,to:replace decomposed plastic studs
in the bleach tank racks and for twelve gears #459240
for both processors.
b. RT-24 -- A cost estimate was requested for removal of
the dryer cabinet and providing a print exit into a
Pakosol bath.
A cost estimate was requested to add another air
tube in the dryer adjacent to the exit squeeze.
A leak in the ferrotype drum dryer was reported
and a proposal was requested to correct the deficiency.
Replacement costs were requested for a defective
terminal contact in the dryer circuit breaker.
c. The costs involved in the above would be chargeable
to PAR 246.
d. Spare parts - RT-12 and RT-24 -- A total of 504, of the
contracted spare parts have been delivered. Fabrica-
tion of the remainder is behind schedule. Consequently
delivery will not be made until the end of July.
6. The prototype high magnification lens set being designed and tested
under PAR 245 is progressing well. The condensor elements for both lenses
are on hand as well as one objective lens. The mechanical assemblies for
both the condensor lenses and the objective lenses are in manufacture. Once
the lenses are assembled, they will be transported to NPIC for focus, align-
ment and calibration on the prototype BPE. This is anticipated to occur some-
time in mid August and will require about 1 1/2 days time on the BPE.
