SUBJECT: Briefing Print Enlarger (Prototype)
TASK/PROBLEM
1. Design, fabricate, and test a prototype briefing print enlarger
(BPE) based upon tests and observations of the breadboard equipment de-
veloped on the combined PAR 202/22+.
2. During this quarter, effort on the project was at its highest
level. The last of the subassembly designs was completed and all detail
drawings for parts fabrication were finished. The electrical system
drawings were completed. All parts have been fabricated with the exception
of a few, and drawings for these were released recently.
3. Activity by the engineering group will continue at a lower rate
in the completion of assembly drawings and in providing engineering follow-
up service for the project,
4. The manufacturing department has started several minor subassemblies
and will proceed with assembly work at a lower man-hour rate than has been
possible in parts fabrication.
5. For the last design work on the project, a series of tests was
made. The purpose was to explore the value of heater elements at the upper
edge of the negative gate enclosure in shortening the time required for
evaporation of the immersion fluid from the film as it is withdrawn upward
from the gate. During these tests it was found that after injection of the
fluid and closing of the gate:
a. There is a bead of excess fluid between the film and the gate
glasses at the periphery of each gate glass.
b. If the gate is opened and the film is withdrawn before the bead
of fluid evaporates, the excess fluid runs down the surface of the film form-
ing a fluid bead along the bottom edge of the film.

c. An extended period of time--one to two minutes-is required
for fluid removal if the excess fluid is not removed by means other than
evaporation.
6. The gate assembly has been designed to remove the bead of fluid
by momentarily touching the bottom edge of the web with two special animal-
hair brushes as the web is withdrawn upward from the gate. Solenoid-
actuated mechanisms move the brushes to touch only the bottom edge of the
film and only as it is moving upward. At other times, the brushes are held
) away from the film. At the end of this report period, a source for the
special brushes was being actively sought..
7. A subcontract was arranged and awarded for the design and fabri-
cation of the prototype Easel Photometer based on the subcontractor's
proprietary commercial product. The prototype Easel Photometer is scheduled
to be delivered by 7 March 1967.
8. On 14 and 15 September, the customer's representative held a con-
ference at the contractor's facility to acquaint three technical liaison
men from other organizations with progress of the development effort. The
discussion covered:
a. Achievements in the completed breadboard, PAR 202/224
b. Design goals
c. Configurations
d. Status.
During this conference, the following comments were made by the customer's
representatives for consideration by the designers:
a., The interchangeable objective lens and the condenser assemblies
should be identified with a particular enlarger-perhaps by serial number.
b. Service covers should be readily removable.
c. Transport caster dollies should be mounted on the frame by
machine screws.

d. De-activation of the lockout of the hand-knob used-for fine
film-position control should not be possible for the operator.
e. Interchangeable lens assemblies should have "full-hand"
handles. All the features suggested were already incorporated or have
since been incorporated in the design.
9. On 9 November, the customer's representatives visited the con-
tractor to review progress (1) on this project and on others under the
contract, and (2) on the seven-unit procurement of BPE's on Contract
t_ I
Task 4.
10. It was expected that the following data would be delivered to the
customer's representatives on 29 Nov 1966:
a. A preliminary Spare Parts List for recommended FAK and Base
Spares, based on engineering judgment.
b. A revised edition of the tentative specification for the BPE,
Specification 469-333, and
c. Installation data for the BPE.
This material was not complete on 29 Nov 1966 and is now scheduled for
delivery by mail by 23 December 1966. Eight copies of each are to be
provided. Copies of a questionnaire used by the customer for installation
engineering data were provided to the contractor to serve as an outline for
the presentation of that information.
PLANNED ACTIVITY
11. In the next quarter it is expected that:
a. The prototype BPE will be assembled and will be nearly ready
for testing.
b. The data described in paragraph 10 will be delivered.
c. The assembly drawings will be completed. This will complete
the drafting effort required on this project except for changes which may
result from problems encountered in fabrication, assembly, and testing work.
