2. The sub3ect task provides for the fabrication of 15 IN-7 time
event markers (TEM) and the development of one ruggedized IN-7 prototype
(TEM-A). Initial development of the IN-7 was accomplished under RD-76,
Task Order C. The TEM and TEM-A are miniature time code generators
controlled by a watch movement. In the TEM the watch is driven by a
manual wind negator spring which when fully wound will provide operation
for a 60-day period. In the TEM-A the watch is driven by an electrically
operated solenoid which pulses the watch winding mechanism once per
minute. In this manner, operation of the unit will continue for a period
determined by the life of the external battery source. When TEM or TEM-A
is electrically interrogated, a series of pulses is presented at the
output terminal. This is a binary coded time group representing the
number of E1.apssl minutes from the time of activation. The TEM and TEM-A
will be used with ELINT systems to denote the time that sample signals
are recorded.
3. The contractor is still experiencing difficulties in fabricating
15 IN-7 prototypes. The primary trouble still remains the same, operation
at room temperature of the remaining 12 units has been satisfactory
however very precise adjustment is necessary to get the units to function
properly at low temperatures. This has been extremely time consuming and
costly and it appears that at the present rate of progress the contractor
will not remain within the contract time and funds. The original
contract provided $31,440 and due to the difficulties experienced by the
contractor the contract was ammended to increase this by $13,585. It had
been previously suggested by the contractor that by relaa~ing the low
temperature specification from -30?C to 0?C $5,000 of the $13,585 could
have been saved. This was presented OC-SPS~EA for consideration. A
decision based on the savings per unit, which is low for what may have
been bought, was made and the -30?C specification was not relaxed.

4. was questioned as to the present status of the 12
units and has stated that all units are completely assembled and have
been checked for operation at room temperature. Several units were
checked at low temperature operation and failed to perform properly.
Considerable time has been spent on these units and they still have not
passed the low temperature specification. was requested 25X1
to run low temperature checks on all units, taking t em down in
increments to -30?C, and report to the writer the results of these tests
At this time the contractor will make an evaluation of the remaining
funds and the work to be accomplished to determine if additional funds
and time are required. It is suggested by the writer that at this time
an evaluation be made to determine if the specification should be
relaxed.
5. Progress of the ruggedized IN-7 was discussed and the present
status is:
a) The unit has been completely serviced and checked and
is ready to be cased and the final testing performed.
b) Case design is in the final stage.
c) The moisture indicator and housing has been selected
and is ready for incorporation in the IN-7 case.
The nitrogen purging adapter kit has been designed and
a procurement source for spare nitrogen bottles has been
located.
e) A storage and shipping case for the IN-7 and accessories
is being procured.
6. The moisture indicator is a small desiccant package contained
in a removable housing which screws into the back of the IN-7. A
plastic window is provided for viewing the indicator. The nitrogen purg-
ing kit consists of an adapter which replaces the indicator package. A
small nitrogen bottle is screwed into the adapter and is punctured by a
needle valve to release the gas into the IN-7. A screw in the front of
the IN-7 is removed to allow the atmosphere in the unit to escape and be
replaced by the nitrogen. One bottle contains eight times the volume
contained in the IN-7. After purging is completed the screw and moisture
indicator are replaced.
7. The storage and shipping case for the IN-7 is a hinged wooden
box with a securing clasp. It is large enough to provide foam mounting
for shock protection and contain the IN-7, mating connector plug, twq
spare moisture indicator units, two spare nitrogen bottles and the
nitrogen purging adapter.

8. The completed ruggedized IN-7 is scheduled for delivery ~+
December 1959? The contractor was requested to notify the writer of
the TN-7 status two weeks prior to the scheduled delivery date so that
the necessary arrangements for evaluation can be initiated.
