Tournapull has devoted consider-
able study to coolants and cutting oils
s machine tools, especially Tourna-
matics, which have special require-
Tents because they hog off much
iao metal to a revolution than do
reast machines. The Tournapull lab
her these studies has developed cut-
rng oil and coolant specifications.
Penia lab, on the other hand, prefers
unload its cutting oil problems on
meliable petroleum product vendors
who are equipped with laboratories
voted exclusively to petroleum
ridies and in whom it has confidence.
Each lab is satisfied its method of
kaling with the problem is best.

slower Gamma ray process. Peoria
requires a full shift to determine the
molybdenum content of a steel sam-
ple. Tournapull does it in 40 minutes.
Tournapull finds the carbon content
i steel with the volumetric Leco car-
*n determinator in three minutes,
xhile Peoria, which has no foundry
urnaces waiting on its analysis, em-
ploys the more leisurely and possibly
more exact gravimetric process. And
so the differences go.
The Georgia lab has the rare dis-
tinction of operating on standards;
is routine determinations and other
activities indexed so that the com-
petent chemists or analysts can make
daily bonus. The Illinois lab keeps
i staff busy, but not on standards.
Control of the Peoria lab is divided.
Walter Brooking, research director, is
responsible for the chemical lab and
for the wire rope and weldrod physi-
nI lab. Norman Dirks, superinten-
dent of heat treat and chief metallur-
gist, manages the general physical-nd oieo specific graviy of Peoria's lubricating
