a complete aescription of it including flow diagrams; if it is a method capable of being illustrated by a sketch or
where it is an apparatus, circuit or mechanical device, the disclosure should consist of a sketch with the parts
numbered with a description of the sketch and method of operation making reference to the numbered parts. If
possible a sr,-t:ific illustrative example and operative description of the invention should be included.
If the space below is inadequate, attach separate drawings or prints and description, properly signed, wit-
nessed and dated.

ceepeeeion of this ring beyond the preeectine tip of the re-entry body anra
ther' -r ineee failure of the front ring.
To preeent this we have designed and tested a compact cooling unit to reduce
this ring temperature to 200' F - 300? F.
re7STe7e:
The design (see Figure 1) consists of forming a water jacket in the ring by clos-
ing th'.) open side with a bonded in fibre glass wall, packing enclosure with an
absorbent material that will hold a maximum amount of water, but will readily.
releace steam upon heating.
Eeeericted escape holes vented to the outside are plugged with a fusible material
deeiened to melt at a specific temperature.
A eIeze weave fibre glass wool baffle across inside of escape holes acts as a
trap and increases efficicnCy.
eeeratine principle is as skin temperature rises heat is condueted to the
eed causes tha water held in the absorbent packing to boil, the 2usf1ie
r
_eelt Alowing the steam to escape to the outside, removing the heat.
S:
pressure is maintained by the sized restricting escape holes.
e epecimen construction (see Figural.) duplicates a 10" eection of ring arei
e.eee en cross sectional area.
The was .10" thick x 10" long x 3" high magnesium thorium sheet. The ring
was cut from magnesium thorium to duplicate the cross sectional area of actual
flieht ring.
The jackets were fibre glass formed over a mahogony mold and held in place by
high temperature rubber and cured in an oven.
The specimens were then packed with absorbent material and the jacket bonded
in place with aero bond p. O. and cured for 30 minutes at 250? F.
_ .
After cure, the specimen was filled with syringe thru escape holes
and sealed. A pressure gage was then attached to a few op. samples
(see figure 1). The specimen was then thermocoupled (seeFigur6'1)4ndaquadaged

Tencrature was recorded with a visi-caeder using chromel-alumal thermocouples,
calibrated in 4n 0? to 500? F oven and .e:etropolated for higher temperatures.
Ice was used as reference junction.
Et source was a bank of 8 G. E. radiant heat quartz lamps, with a polished
linum reflector mounted behind.
ariST P7.7CEDURE
Th specimens were weighed before and after jacket installation to determine
jacket weight, and after waterinstallation to determine water weight.
The specimens were then placed 2.5 inches from heat lamps. This distance
was determined by testing a celibration magnesium sheet .1 x 8 x 10 with a
thermocouple installed on the center of the side away from lamps and within .03
inches of heated side. All skin thermocouples were installed in this manner.
The specimen was then painted with a thin layer .of aquadag and distance tested
Lor 950o F in 100 seconds. (See Figure 2 Temperature vs TiM3 Curve)
A second calibration specimen with skin and ringbut no packing or water
jacket was tested for comparison purposes (See Figure 3).
All jacketed specimens were then tested, all had a thermocouple installed in
:in as well as the ring to determine heat sink characteristics and constant
?ere? output. For locations, see Figure 1.
