During the first week in January, five clocks were subjected to the r~t;o0 r; 67
-40?F. test, of which three clocks failed to fire. Due to the failures
in both the 30 day high temperature storage test the previous month
and the -10OF. test, it was recommended by the Project Officer that
the above tests be repeated with new clocks. Seven canned clocks
were selected from stock and all were subjected to the quick leak
test. After this test in which it was found that one of the cans
leaked, two cans were subjected to the 10 foot drop.test and in
one case the lid split open at the canning seal, (See Photograph)
The other can from the drop test was again subjected to the quick.
leak test and found to leak.
Following these tests all seven clocks were run twice at ambient temp-
erature to determine their accuracy, and the first five were then
placed face down at 130?F. for the 30 day test, The other two clocks,
(numbers 6 and 7, which had been dropped), were subjected to the 200 ft,
water submergence test. Both functioned normally in this test, but
on the ambient rerun to check for accuracy, one failed to fire. This
clock was set aside for dispatch to the Project Officer for examination
after cursory inspection indicated that the clock had failed to run
long enough to fire despite a full wind. ? n
The second clock (no-7) was rerun a second time and then with two
clocks from the original lot (nos. 1 and 2) were attached to soldered
up adapters and run for 24 hours submerged_in gasoline. All three
clocks functioned normally, but on the ambient rerun at the end of
the test, one clock (no. 7) failed to fire. Failure appeared to be
due to the same cause as before, and it was also dispatched to the
Project Officer for examination,
Future Work
The 30 day 130?F test will be completed in the middle of February and
the clocks will then be subjected to the --40?F. test,

At the beginning, of December preparations were made to drop
from two to five canned clocks, dependent, upon the results
of the initial two drops. Photographs No. 1 and 2, show
the deformation of the cans, after each had been dropped
twice, once sideways and once face dove.
Though in the case of can No.' l the rolled edge was deformed
to the point that it might not be watertight, only super-
ficial damage was done to the contents.' Namely the winding
key and chain became detached from the clock.`" (See Photo-
graph No. 3) In the other can the clock fell against the
side of tham,can producing an indentation in the side of the
latter, caused by the starting knob striking the can. This
knob was faand to be slightly stiff to operate, In addition
one of the keys attached. to the outaide of the can broke
off , , (See Photograph No. 2) Both clocks and the other
three belonging to this group were run twice at ambient
to determine their accuracy, at the completion of the above
test;'

Towards the end of the month the thirty day, 130? P,' test was
completed:' After allowing the clocks to return to ambient
temperature they were set and run for twenty-four hours and
all five failed to fire,' After standing over the four day
holiday week-end they were rerun and this time all five
clocks fired` However, there was some deviation from their
original accuracy prior to heating, so it was deemed desir-
able to rerun them to determine their reliability before
using them on the low temperature test. Both the rerun and
the low temperature tests should be completed by early
January.'
During the course of the month two clocks, one taken from
a can that had been dropped and one other, both previously
checked for accuracy, were equipped with an adapter whose
firing pin had been removed and the end soldered water
tight, they were then submerged in water at a pressure
equal to 200 feet and run for twenty-four hours. One clock
functioned normally and one failed, the latter had been
through the drop test and had functioned normally on the
two accuracy tests. This clock was rerun. and when it
failed a second time was examined closely.' The cause of
the failure was found to be due to a broken main spring,
Therefore, another clock will be selected and the test
repeated"
Future Work
The low temperature test and the gasoline submergence test,
including the retesting of one clock with an initiator will
be performed'

During the first part of November the five (5) clocks that had been ~' ~~ -~o~
in storage for twenty (20) days at 130? P. were removed and tested ~ATEi~
at ambient temperature for accuracy. The results of the test showed
that three (3) clocks fell within the time limits set, but two (2) Z bl:c S ~O
clocks were a little over two minutes respectively fast and slow.
The information was reported to the Project Officer who scheduled
a trip and discussed the program at some length. On the basis of
this discussion the general scope was changed, but only in the
details of each test.
First, the tests would all be rerun using new clocks, instead of the
reworked ones. In addition the clocks would all be run twice before
they were tested in order to determine the accuracy of each clock
more exactly. Further two (2) canned clocks would be dropped ti-rice
from ten (10) feet and the condition of the cans and clocks inspected
and tested. C or,_
Following the above changes in the scope, the test on the five (5)
clocks at high temperature was immediately started. The clocks
were run for two (2), twenty-four periods. Of the five (5)
clocks, four (4) clocks had a variation of from 15 seconds to
1 minute and 55 seconds between first and second runnings. The
fifth clock had a difference of 6 minutes and 41 seconds. The
clocks, each one numbered, were then placed face down at 1300 F.
and will remain for 30 days.
Future Work
The functioning of four (4) clocks after 24 hour submergence under
gasoline will be tested. Adapters will be attached, but the firing
pins will be cut off and the adapters sealed against possible water
penetration.
Two (2) canned clocks will be dropped from 10 feet, both sideways
and on one face.

Work was initiated during the month of October on the testing of the
JAP 2L-hour clocks. Five (5) clocks were placed in the surveillance
cabinet at 130 deg. F and will remain for 20 days when they will then
be started and checked for accuracy at that temperature. This test
is due for ccilpletion early next month.
Tests of the functioning of the clock attached to the limpet were also
canpleted. In this test the clock was set for 20 minutes but not
started and the safety pin was not removed. It was then attached via
its adapter to an M-3L detonator and a limpet. Care was taken to see
that all joints were screwed up as tightly as possible. The assembled
unit was then left submerged in 18 inches of water for 2L hours. The
entire unit was then removed from the water and the outside of the
clock carefully dried off and inspected by visual observation to see
whether any water had entered. The clock was then started and the
safety removed at which time the whole unit was re-submerged. In this
test the limpet was successfully initiated.
A similar test using a clock attached to an initiator was also per-
formed, in which both were put under 18 inches of gasoline for a pe-
riod of 24 hours. However, at the end of 2L. hours, when the unit was
removed for inspection, it was noted that gasoline had in some way
entered the clock. The clock was set for 20 minutes, started as in
the previous experiment and replaced in the gasoline. After waiting
for a period of one hour, the clock had not functioned, and the
initiator was therefore detonated using the secondary electrical firing
system.
At the request of the Project Officer this test will be re-run with
an additional four (Li) clocks. However, the initiator will be omitted,
the adapter will have its pin cut off and the open end will be welded
shut.
Future Work
Complete high temperature storage test, low temperature storage test,
200 foot water immersion test, and the gasoline immersion test.

The month of January bro (10
ught the progress of the contract through
the major portion of the scope. The tripping error test has been
completed on the twelve hour clocks and a portion of the cold test.
The cold test work has been done on the small 4+5 minute clocks
which are now undergoing tests in the hot cabinet.
In general, the small clocks have performed satisfactorily, with
only two units mechanically defective. One other unit has run
consistently fast. In the cold test, most of the clocks worked
satisfactorily at -5?F. although three out of four units failed
to operate at -e100F.
The twenty-four hour clocks, on the whole, are not as satisfactory.
In the sas is" test four units were inoperative. As testing
progressed, some of these units became operative and others
developed defects. During the later part of the tripping error
tests, five units were set aside as being mechanically defective
and others were subject to erratic stoppages. Most of the re-
mainder were functioning correctly at -10'F. although two were
running slow.
The testing program is expected to be completed approximately
February 15, at which time the final report will be written.

Work during December primarily concerned planning each
contemplated test. The details of these tests will be
found on a separate sheet of this report.
Jigs have been completed to test both the large and the
small clocks. A means has been provided so that the
small clock trips an alarm light. The large clock auto-
matically switches off its individual master clock when
tripped.
Tests A and B are completed on the small clocks and will
continue on the large clocks.
