TURN DISCOVERIES
Find New Use for ButtermiIk
and Perfect Enamel

PVefessor Robert Kennedy Duncan
.lds announced that important discov-
ert9s have been made and completed in
rhe" department of industrial chemistry
at:flTe University Of Kansas which will
pfoNe of inestimable value 10 many in
dastraes throughout the country
Tile most important of, these discov-
cries. probably is in the manufacture
ef casein. E. J.. Tague. a fellow in in
easIrjal chemistry, has perfected a pro-
eesg of manufacturing this product
fLQlll~. buttermilk something chemists
haTe.beeu unable TO accomplish here
totore- says the New York Herald.
I@g0e spent two years in experiment
Eg* The donors Of the fellowship, an
eastern manufacturing concern, pur-
O. ased all the apparatus and materials
needed 10 carry on the work.
Buttermilk has always been a waste
pE6Quct Millions OF gallons thrown
away by creameries can now be turned
Into a. practical benefit for use in the
manufacture Of casein. which is extern
siyely used in the sizing Of paper by
paper mills. II is also used in manu-
facturing brushes. combs, billiard balls
and many other articles.
When Tague finally completed his
process and submitted it to the donors
the new method Of manufacturing
Cssein was tested thoroughly in a prac-
ticsl way and found TO be a complete
success. The result is that a million
dollar plant viii be built soon for its
manufacture from buttermilk Fur
thermore, a contract has been made
whereby the inventor is TO receive 10
per cent Of the net profits of the busi-
ness
Archie weith and Frank Brock are
80 other students in the same depart
Esnt who have made discoveries
scarcely less important. After work
ing a year and a half these young men
have found a way to make an enamel
for steel containing tanks that has the
same coeficient of expansion as the
steel itself BY the use Of their process
OF manufacture an enamel is obtained
that. .'will not crack under conditions Of
extreme heat or cold. The enamel is
also resistant, will flow over the steel
properly in the enameling process and
IS resistant to acids. It can be used as
lining for steel tanks and towers in
various kinds Of industrial occupations
Professor Duncan left for Rochester.
y 2. 10 day to close contact with an
"a stern concern which has obtained the
rights OF manufacture Of this enamel.
He stated that the inventors, Archie
Weith and Frank Brock, would receive
large royalties.
Two years ago the National bakers
association granted a fellowship pay
8ng $500 a year to Henry Krohman TO
carry on experiments in search Of some
means Of making salt rising bread uni
form in quality.
The, efforts Of KrollThan also have
proved entirely successful. He has
discovered a way TO isolate the microbe
which causes the bread TO rise. This
means that bakers will be enabled to
supply bread Of better quality and
lower in price to consumers all over
the country.
Oat Of Is fellowships these three re-
lnaFkable discoveries have been brought |
about. Other students are now engaged /
in experimental work in various other /
fields, and Professor Duncan stated that |
q number Of them undoubtedly would |
accomplish things fully as important as
the discoveries already made.
The funds for these experimental
purposes come from manufacturing
concerns throughout the United States.
rhlse corporations, of course, refuse TO
lIsTe their names given out until they
are protected by patents for the eXclu-
sive rights Of sale or manufacture of
anE products or processes resulting
frosh the experiments. In order TO OBJ
tain the fellowslips the university
mast sign y contract which protects
Inc donors for 4 period Of three years.
after which all discoveries made and
.Ae names OF donors OF the fellowships
UiG be made public.
