10.3.i Liners and discs shall be heated in a dry oven to approximately
200?F for at least one (1) hour prior to use. Materials allowed
to remain unused or open to ambient conditions for more than
two (2) hours shall be redried.
10.3.4 Cans and liners - two (2) dried cushioning discs shall be inserted
into the can and pushed tightly against the bottom closure. A
single-faced corrugated liner shall then be rolled, corrugated
face inward, to fit the can I.D. and then inserted to line the

to prevent movement.
10.3.5 The clockwork mechanism, after having been finally checked, shall

10.3.5.1 The mainspring shall be wound one half (1/2) tight and
the bottom cover cap left off.
10.3.5.2 The cocking device shall be removed from the neck

10.3.5.3 The time setting dials shall be rotated until the
tripping lever falls into the slot and the firing pin
is released. The starting ring shall be turned to the
"stop" (Steht") position.
10.3.5.4 The safety screw plug shall be screwed tightly into
place in the clockwork case neck.
10.3.5.5 The front window retainer ring shall be loosened one (1)
full turn.
10.3.5.6 The bottom cap shall be replaced and screwed only halfway
on to the case threads.
10.3.5.7 The entire clockwork case shall then be placed in an
evacuation chamber and slowly evacuated to at least
24" Hg vacuum and held at that pressure for at least two
(2) minutes. The chamber shall be slowly filled with

 Sanitized Copy Approved for Release 2011/05/04: CIA-RDP78-03642A000600090003-3
nitrogen gas to return the pressure to atmospheric over
a two (2) minute period. The front window retainer
ring and the bottom cap shall then be quickly and
tightly sealed.
10.3.5.8 The base of the clockwork case shall then be wrapped in
a single layer of aluminum foil. The base shall be
placed in the center of the foil and the foil edges
gathered up toward the case neck. The arming screw
and chain, shall be led out of the foil gathering and
the foil shall then be tightly compressed about the
case. The foil about the neck shall be gathered and
tightly secured by a double turn of tape. A one (1)
inch section of tape shall be folded back upon itself
to provide a removal tab for the tape.
10.3.5.9 A "doughnut" disc, complete with two (2) coupling base
adapters and one (1) special aluminum adapter shall then
be pushed over the neck of the clockwork case and down
against the safety screw.
10.3.5.10 L wath er shall then be placed over the arming screw
stem and the stem pushed upward through the remaining
hole in the "doughnut" disc. A second washer shall
then be placed over the arming screw stem and the nut
screwed tightly in place. The disc shall then be
rotated about the clockwork case neck to remove all
slack from the arming screw chain.
10.3.5.11 The cocking device shall then be screwed tightly into
place in the case neck threads.
10.4 Method of Unit Packaging
10.4.1 The foil-wrapped clockwork case and its installed "doughnut" ring
shall be inserted carefully into the lined can. The "doughnut"

 Sanitized Copy Approved for Release 2011/05/04: CIA-RDP78-03642A000600090003-3
ring shall be guided into place to prevent its being creased
or broken, and shall be pushed downward in the can until it
contacts the upper edge of the can liner.
10.4.2 At the discretion of the Contracting Authority, the instruction
sheet may be inserted into the can at this point. If this is
to be done, the sheet shall be folded to approximately 4" x 1"
dimensions and rolled to fit over the cocking device and around
to clockwork case neck.
10.4.3 Three (3) flat cushioning discs shall then be placed over the
cocking device and the can cover put in place.
10.4.4 The can cover shall then be machine-sealed in place.
10.4.5 The 1/1611 D holes in the can covers shall then be punched through
with a sharp pointed tool.
10.4.6 Nitrogen gas at a regulated pressure of three (3) psig maximum
shall then be bled into the top hole, via a hypodermic needle
or similar tube, for a minimum of three (3) minutes.
10.4.7 Upon removal of the gas bleeder tube, the top tear-strip key shall
be immediately sweat-soldered in place over the top bleeder hole.
Sufficient solder shall be used to completely seal the hole. A
minimum of flux shall be used.
10.4.8 The same process shall be repeated immediately for the bottom
bleeder hole.
10.4.9 Both soldered joints shall then be cleaned of excess flux and
brush- or spray- coated with a moisture-proofing paint or lacquer
of the same base color as that used on the can.
10.5 Testing and Inspection of Unit Package
10.5.1 Leakage Tests shall be run on each can to establish the complete
air tightness of each joint, seam and closure. This test shall
consist of the following:
10.5.1.1 The can shall be completely immersed in water at a
Sanitized Copy Approved for Release 2011/05/04: CIA-RDP78-03642A000600090003-3
 Sanitized Copy Approved for Release 2011/05/04: CIA-RDP78-03642A000600090003-3
temperature of between 140 and 160?F.
10.5.1.2 Bubbles entrained on the can surface at entry shall
be brushed or wiped off immediately after immersion.
10.5.1.3 Immersion shall continue for at least two (2) minutes.
10.5.1.4 Acceptance of the package shall be made if no bubbles
are observed from any of the seams or closures except
the rolled, double-seam can--top seals. Small, slow
forming bubbles for a maximum of 15 seconds from these
seams are acceptable.
10.5.1.5 Rejecti on of the package shall be made if any bubbles
are observed from any source but the can-top seams.
Rejection shall be made if rapidly forming bubbles are
observed from the can-top seams or slow continuously
forming bubbles from these points are observed for
more than 15 seconds after immersion.
10.5.1.6 Rework of any seal or closure, except the can-top seals,
is acceptable. Reworked cans shall be reinspected as
specified above. No resealing or rework of top rolled
seams is acceptable.
10.5.1.7 Drying - If a can is to be reworked for reason of
leakage, it shall be wiped dry immediately after removal
from the water bath in order to prevent moisture entry
into the package via the lead as a result of the partial
vacuum formed as the can cools to ambient temperature.
