1. The purpose of this trip was to obtain firsthand information concerning
systems developed by the above-mentioned companies and their capabilities
25X1 A9a applicable to our follow-on OWVL (One Way Voice Link) synthesizer program.
25X1 C4a
25X1 C4a The undersigned and Mr9 represented themselves as
at both of the above establishments.
25X1A5a1 At the operation of their audio teaching machine and its possible
?- a lication to our requirements were discussed in detail with Messrs. 25X1 A5a1
25X1A5a1 . The audio teaching unit operates with servo or solenoid-
actuated heads on a tape loop that has one hundred and twenty-eight 4 second
tracks. The servo-controlled head did not seem to be reliable. The solenoid-
actuated slide bar of 16 heads was their approach to the problem to improve
over the servo-controlled head. It seemed to work quite well, but the system
_ as a whole is not very impressive in that it is very little different than our
present system with the exception that the head is positioned automatically.
The disadvantages would be in tape and head wear and its inability to handle
our requirement for fast tape preparation. 25X1A5a1

Systems; and , Supervisor, Digital Systems Development. The
25X1A5a1 system consists pri~~~ marily of 4 film strips, 32 tracks per strip with 7 seconds
per strip. It accommodates message lengths of o.6 to 4.2 seconds. Equipment
consists of a photo tube which is illuminated through matrix shutter plates
that position a light source on film strips attached to a rotating drum.
25X1A5a1 developed a system for the FAA for automatic weather broad-
-- c?n.^tini(. This system has been functioning well. The advantage of the system
It, that there is no head wear and that a life of 1000 hours can be expected
.Prom one illuminating lamp. The lamp has a single hot filament and therefore
has no alignment problems. The photo mu tiplier tube can withstand +20 volts
variation with only 1.5 signal variation. There are two possible disadvantages:
it is not known to what degree of ruggedness the system could be built; and
all known methods to date for making master storage film strips are involved
costly. has an idea in semi-breadboard form for a
25X1 Asa himpler unit, and the system quite possibly could lend itself to fast master
tape preparation.
