the Agency.
2. Teak Order C involved the development of a Time Event
Marker (TEM), IN-7, and a Signal Actuate Device (SAD), CII-30 for
11+D Projects 2115 and 2116, respectively. The task was formalized
on 28 May 19560 and to date a total of $1530097.00 has been invested.
3. The Time Event Marker is a mtniature time-code generator
(5" x 1-3/4" x 2") controlled by a watch movement. The watch is
driven by a constant-torque spring motor which when fully wound
and mechanically released will operate the movement for a period
of 60 days. When the TEM is electrically interrogated, a series
of pulses is presented at the output terminals. This coded time
group represents the number of elapsed minutes from the time of
activation. TENIwill be used with ELINT systems to denote the
time of day that a sample signal is recorded.
4. The engineering model of the TEM was delivered on
3 April 1958, inspected by R401 then forwarded to SPD/EA for test
and evaluation. Laboratory tests have proven satisfactory electrical
operation; however, the unit appears somewhat fragile for field use.
Experimental field tests are in progress with the unit repackaged in
shock absorbent material.
5. SPD/EA has informally requested that 11+D arrange for the
procurement of 15 prototype Time Event Markers in addition to
initiating a redesign program for ruggedizing the construction.
The purpose of building 15 prototypes based on the present design
is to satisfy pending field requirements as soon as possible.

the time, and changing deliverable items of Teak Order C is in
process. This change will provide delivery of one sample prototype
unit and a more accurate set of engineering drawings. On the
assumption that the above change in contract will be made,
has prepared a cost proposal of $31,440.00 on a CWF basis for the
production of the 15 TEM units.
6. The prime purpose of this meeting was to outline
environmental specifications for the TEM design. The following
design goals were considered feasible:
Operating Temperature: -40�C to +70�C
Humidity: 100% at 70�C for four hours.
(The unit will be completely sealed and may require a desiccant).
Altitude: 11.000 feet at -40�C
(Might iequire pressure release valve).
Shock and Vibration: Specification MIL E-52-72-A
Shock-Paragraph 4.15.2.1
(18 impacts of 15 G's each)
Vibration Procedure No. 9: 10 GIs, 5 to 55 cycles per second
(these specifications should be met without isolators. Isolators
will be added as a safety factor when mounting to vehicle frame.)
Fungus Proofing: MIL-T-152-A
(external coating)

7. In order to meet these environmental specifications certain
changes in mechanical design will be necessary. A positive disc
locking device will be required to prevent accidental disc retheting
due to angular acceleration. It may be necessary to employ an electric
winding mechanism if the present negator spring will not provide
reasonably constant torque over the temperature range. Shaft diameters,
disc and relay contact pressures may have to be increased. This ruggedizatica
process can be accomplished only at the expense of power. Present total
power consumed over a sixty-day period is estimated at 1 ampere hour or
approximately 1 cubic inch of battery. The redesigned TEM (IN-7A) should
not require more than double this power. A technical and cost proposal
for this redesign phase is expected within the next two or three weeks.
8. The Signal Actuate Device (SAD) will be used either with
TEM or independently. Upon signal presence, a bi-stable multivibrator
actuates a relay to turn on a recorder. At the end of a preset recording
time period of 17L 2, or 5 minutes, the SAD will interrogate TEM and
transfer the TEM output to the recorder input. Each of these equipments
performs automatically, what is now a manual operation 50X1

9. The engineering model SAD was delivered in June 1958,
inspected by 114D, and forwarded to SPD/EA for test and evaluation.
These tests confirmed the need for a threshold control. The
contractor is adding such a control to a breadboard model SAD
which remains at the plant. The threshold control will be accessible
t the front panel and will work as a signal voltage divider.
suggested that a separate connector be used for signal
input to possibly eliminate actuation by power switching transients.
10. advised that final engineering reports were
being written on both projects. The contractor's technical progress
is satisfactory and his cooperation during the engineering model to
prototype transition is considered commendable.
