We are pleased to provide the ninth in a series of Monthly Progress Reports
covering the effort expended on subject contract during the period of April 2, 1965
to May 1, 1965.
Clean Room Erection:
As previously reported all major work for the installation forthe clean
rooms is complete. The outstanding work may be separated into two phases;
1. Clearing of Quality Control Inspection queries.
2. Qualifying the performance of the clean room to meet the contract
requirements.
Work by to satisfy and clear inspection snags is
proceeding, and is scheduled for completion by May 8th.
Daily record charts of the performance of the control equipment shows varia-
tions outside the contractual requirements of maintaining any selected temperature
between the range of 68?F. and 85?F. within ? 2?F. and 45% relative humidity
within + 5%. An evaluation of the whole system has been conducted by the sub-
contractors concerned, and modifications as necessary put into effect. These
changes included the de-sensitizing of the pneumatic control system to eliminate
transients and the addition of a damper control over the fresh air intake. The
system was designed to accomodate a working load of the HTA/5 processor plus
lighting and a maximum working personnel load of 15 with approximately 60 changes
of air per hour. Modification, are therefore required to reduce the outside air intake
to compensate for the lock of this load. Additional heater strips are also being

installed to assist control of relative humidity. These modifications are scheduled
for completion by May 10. A final scrubbing, washing down, and cleaning of the
rooms is scheduled for the week ending May 16, 1965. The final acceptance tests
to demonstrate the performance of the installation to specification is scheduled
for the week ending May 23, 1965.
Research Program:
1. The following assignments were continued during this reporting period;
Evaluation of the effect of elevated processing
temperatures on emulsions.
To determine the coefficient of friction of film.
Design and testing of air bearings.
Liquid bearing incorporating a built-in pump.
- During this reporting period of the contract, film
type 5427, derographic duplicating was tested in continuance of the
elevated temperature processing studies. The leading particulars of
this film are as follows:
Base thickness - 5.2 mils, acetate butyrate without gel backing.
Emulsion thickness - 0.42 mils.
Sensitivity - Blue sensitivity, fine grain emulsion.
RMS Granularity - Kodak developer DK-50 .043 (D net = 1.0)

Many problems have been encountered during the research on the behavior
of film, type 5427 during elevated temperature processing. During the

preliminary testing of the emulsion, it was apparent that as the processing
temperature increased, the more unstable the emulsion reacted in terms
of gamma. This result suggests that the rigid standards set for this
research program, may require relaxing to accept the lack of stability
in the high temperature processing of this emulsion.
The published data on this film establishes that a gamma of 1.90 would
be obtained for an 8 minute process in D-76 at 68?F. Using this process
as the control, a series of five tests were performed yielding an average
gamma of 2.81. The gamma difference between the highest and lowest
product of all the tests was 0.10 ,,which falls within the tolerance of
+ 0.10 laid down for this program.
In the case of film samples processed for 45 seconds at 118?F., an average
gamma of 2.37 was produced, and the difference between the highest and
lowest gamma was 0.29, well beyond the required tolerance of + 0.10.
In the next reporting period the processing time at 118?F. will be increased
to the point at which the gamma equals that of the control sample (2-81).
Once this is accomplished, further tests will be performed to determine
if a time/temperature combination can be found to produce a result within
the required tolerance (t 0.10)'.
The increase in processing temperature from 68 0 F. to 118?F. resulted in
a sharp increase in chemical fog (base + fog) from .05 to .17. To determine
the repeatability of the results many replicate tests will be necessary.

3. Assignment ~- This assignment has been completed, the data
reduced and the final report prepared and in printing. This report will be
submitted shortly under separate cover.
4. Assi nment Preliminary drawings have been made for an air
bearing in w ich a blower is an integral part of the bearing. Manufacture
of parts is expected to commence as soon as detail drawings are
available.
5. Assignments_____] - A series of pressure determinations at each of the 161
holes in the plastic plenum mounted on the bearing was completed for three
differenct motor speeds - 296, 357 and 420 rpm. The latter proved to be
approximately the limit for reading on the new inclined manometer. The
manometer had a slope ratio of 4.123:1 and was filled with C . P. carbon
tetrachloride (specific gravity 1.585) for fluid. The water above the legs
was tinted with blue dye to facilitate reading the meniscus to 0.01".
The slight solubility of carbon tetrachloride caused some turbidity at the
interface after a few hours operation, so the instrument was cleaned and
the solution replaced for each run.

The manometer was..leveled and its zero reading adjusted to coincide
with the rotary shaft centerline for the series of tests. The hydraulic
head (distance to the surface of the water in the tank) was accurately
measured at the start and maintained constant during the tests by small
additions of water to replace dragout and evaporation. The distance
of each_row of tapped pressure holes above the datum plane was recorded
for a correction factor.
The data has not been completely reduced from inches of water (corrected
from the carbon tetrachloride gravity) to pounds per square inch as yet,
since considerable tedious mathematics is required. However, the
interrelated ratios will not be changed and some interesting hypotheses
can be formulated. As a generalization on all three runs, the pressure
pattern had a characteristic conformation. If observed from the front
end (blades moving in a clockwise direction), there was a sharp pressure
area along the edge of the 1200 masking plate at the bottom of the stator
cage. This fell off somewhat and then built. to a maximum at the top
(according to its design parameter) and continued with some fall-off
around to the trailing edge. It is a reasonable conjecture that this
pressure pattern may be the:-.cause of the fluctuations (or loping) formerly
observed when the bearing was supporting a film loop. This supposition
should be tested. It should be noted that this loping effect was virtually
eliminated by the addition of a perforated screen which is discussed
further on.
It is interesting to note that wherever an individual reading was lower
than the points surrounding it, this phenomenon was repeated at each
of the other speeds. It is proposed to make some three-dimensional
plastic models of the pressure field so that interrelations can be observed
in context. Some surge was noted in the manometer readings, particulary
at the lower speeds and near the outer edges of the plastic plenum where
the velocity gradient fell off. This amounted to approximately f .15
average at 296 to f 10 inches at 320 rpm. On the other hand, there were
occasional slow surges of an inch or more at all speeds examined at the
edges of the plenum. These will be investigated.
If the velocity is assumed to be indentical to impellor speed, the observed
pressure readings follow almost exactly the square of the velocity law.
This gives added credance to the readings. Several point checks were
made for pressure lift and these followed closely the observed measurements
for 4-,7-, and 11-pound spool weights tested earlier in the program at
speeds of about 280 to 425. In one test, the hydraulic head was allowed
to fall to a point at which the pressure pattern closely approached that

shown in one of the photographs in the February Interim Report. When
the room was darkened, a strobe light adjusted to blade speed showed
the various flow patterns, area of cavitation and inlet and outlet stream
paths. Some photographs of this effect will be attempted.
In the next reporting period additional tests will be performed with the
perforated aluminum stabilizing screen added. Thereafter a series of tests in
which the helix-spring cage is replaced with a plastic cage will be conducted.
This latter series of tests will enable us to machine the cage as required to obtain
the most satisfactory configuration.
