Present :
The purpose of the visit was the finalization of the Black Box design, with
special emphasis on the control points and method.
1. The first item to come up was the operators chair. The final one is
in place and will require some drawing modifications. See attached
sketch .for dimensions and details. These should be incorporatedthat
into the working drawings before they go out for bid. It seems
overturn may be a problem because of a limited turn radius in the
cockpit and no limit outside the cockpit.

3. The pipes thru the foundation were discussed briefly.
4. The discomfort of the air velocity was discussed. Their system has
a 5 fps velocity which is felt to be too high and is to be modified
downward to 3 fps by changing the pulleys.
5. Their facility was discussed and completion has been slowed due to
conditions beyond control. Tentatively, the test visit is planned
for two days during the weeks of 7 or 14 July. Terry does not
necessarily have to be present. We are going to test the room for
temper._a.-ture control and for cleanliness. The reason for the testing
was discussed also. That is the establishment of the conditions under
which it will operate in our building. They have no humidity control

6. The, control points of the two high velocity air jets came wer

Several alternatives were discussed. We decided that iall two Barrier Blocks downstream of the heat source and carry two low im-
pedance leads to the back of the instrument. Our contractor would
attach a 3500 ohm thermistor on the Barrier Block, attach a small
screen cover open on two ends and apply the required amplification,
signal conversion and other controls for proper of the
(Spring-
field equipment. (Send for
field N.J.) (VLCO 35 A 1 Thermistor R 8). We are o send the Barber STAT
Coleman Cone Thermostat time constant to Terry. The Barrier Blocks
are by Cinch - Jones Series 172 in Allied Cat.

7. The Black Box and controls came into focus. Several ideas were
discussed. The final plan is as follows:
We will. have a 12 wire terminal block. (This includes the
r loin controls for the Punka Reheat Coils). -The other eight
terminals will be from the thermistors that will control the
black box outputs. Four may be all required, but we will have
eight just in case. We will-base the design of a thermistor by
others with 3500 ohm resistance similar to those called out
above.
We are to ascertain the time constant for the Barber Coleman Cone
thermostat and send this information t
The thermistor sensor should be investigated because of their inherent
requirement for calibration. .Mast catalog items list plus or minus
25% for range in the .010 to .013 dia beads. We will probably require
shunt or series resistors or. T pads.
10. The hIL ick box compressor will have to have an oiless compressor.
11. The black box should have 50 cycle capability just in case. It will
be needed in September 1, 1969, F.O.B The shipping
conLa-aine.r shout be suitable for re-use a minimum o ive (5) times.
Delivery to be by Air Freight. We will send two copies of the pro-
posal tol for review and continent. The unit should have
flow measuring. devices for permanent indication (not recording).
These should be pressure adjustment and pressure gages. One
excellent gage with a manifold tap so it can be used for all readings.
12. We made the statement that the run-around electronic air system
has a 1?F plus or minus temperature control capability.
13. We confirmed back door access to the space with an adjustable truck
unloading dock device and a crane for straight lifting. Also, the
ability to roll pneumatic packages to the use point for unpacking.
14. The requirement for security conduits and telephone conduits was
discussed. These should be added to the drawings if required.
