SAVES MILLIONS EARLY.
American ereameries are Indebted
10 the laboratory work Of a uni
iversIty professor for the machin.
which has enabled them TO save
millions OF dollars yearly in separst-
ing cream from milk. according 20
the Engineering Foundation. which,
with the National Research Council
and other agencies. Is organizine
Industrial research on a nationwide
scale. The invention Of this ma
chine was another striking iIlustra- q
uon OF laboratory researches car
REC on with no immediate motive
other than the discovering Of the
laws OF nature resulting in inven-
uons or priceless value TO this coun-
try. says the statement Of the
Foundation issued from its national
Headquarters. 20 West Thirty-ninth
Street. New York city.
The immediate suggestion OF the
valuable invention OF the centri-
fugal creamer came from teaching
and laboratory research which had
been undertaken to extend the
knowledge Of centrifugal action"

In 1876 while teaching In the
Central High Schol % Philadelphia.
Professor Elihu Thomson had been
using before his classes the whirlinE
machines and models. common in
ca binets OF philosophical apparatus 4
for illustrating the central forces"

promptness with which the sedi-

vessel. and IL occurred TO him that
the applications OF the phenomena
of centrifugal force might be con-
sidersbly extended. a. in the cellar
ing OF Clayey or muddy liquids. or
liquids having materials in suspen-
sion: the separation Of fluids Of
different densities. especially the re
moval Of cream from milk. which. of
course. was carried out on a large
scale by other methods. with ProfeS-
sor Z. J. Houston. who assisted.
4 was believed that 81 a continu-
ousiy operating machine could be
devised for separation. especially ~
cream from milk. notable step il
advance would be made. such 4 ma ,
chine would involve the feeding in
Of the milk while the machine was
kept at high speed. and the de
livery OF cream and the skinned
milk from separate outlets

for the separation Of bacteria from
cultures and for other roncentra-
tinns. was invented. This type y,
apparatus found application through
a friend Of the inventor to the con
,centration Of Photographic emul-
sionS.
The development % this type OF
centrifuEe was however, incidental
only 20 the further and greater an
pI:cation for cream separation In
the meantime inventions which had
before then been made in this par
tIc,rlar field were looked up care
fully: but NJ example was FOUND
of any such machine having been
produced. which could be kept run

Who h,d before this period dc
iyaloped and patented an intermit-
zen, tyne 81 centrifugal Creamcr. IN
which the machine was stopped be

moved before the reception OF an
other.
De T.aveI apparently made the
same invention independently later.
snd in applying for patent found
,ba, thomson & Houston were ahead
: This resulted in his conceoins

combination Of interests soon FOL
LEVIED which led TO the production
and exploitation on large scale OF
the earliest types Of centrifuEai

considered an essential IN every
