- of silica gel about 6' [feet] tall + 10" [inches] in
diam [diameter] (contains the gel in removable
serum cannisters) then through a
cannister of (KOH?) [potassium hydroxide] + then another
Silica gel [therefore symbol] air flow is monitored
by a ball type flowmeter.
O2 [oxygen] is bled into the system as
follows. O2 [oxygen] comes from cylinders into
a water bath type of spirometer
that keeps the pressure constant.
This is kept operating by a water
tube gadget that activates switches
when empty + when full thus
starting + stopping the filling
procedure. O [oxygen] is metered on
a circular dial flowmeter.
There are gadgets on the
side of the chamber to permit
the adjustment of internal pressure.
Temp. [temperature] control is handled by
a best exchanger system consisting
of panels of coild [coiled] [illegible word crossed out] copper pipes
between what looks like magnesium or
anodized aluminum sandwiches. These
are controlled in 3 batteries, Head,
middle + tail. They are fron [word crossed out]
loaded [word crossed out] or brine loaded + operate
from a refrigerator bath in
which coils are immersed in
a brine bath that is either heater
with immersion heaters or
cooled by standard refrigeration.
Motors or moving parts
then are refrigerator, oxygen
pressure equalizer, air pumps.
A battery of leads passes
into the unit for attaching 12
separate thermistors.
He has done some very interesting
work on the reactions of sheep to
changes in temperature etc. It
is in press just now but I
saw his graphs. They are just
what we are driving at.
He finds that the greater part
of the water loss even of non
sweating animals is through the
skin. He has found that the living
skin constantly changes its
heat conductivity contrary to the
finding of Irvine et al on dead skin
Small thermocouplers in the ears have
revealed them as important heat losing
organs
