What the world and the United
States owes to dehocculated graphite
/ in the winning OF the war and the
/ wonders Of dehOcculation is known to
/ only q few persons in the United
/ States. In an issue Of the most widely

That this vast sum OF over one bill
lion dollars was saved and that hun-
dreds OF thousands Of tons Of coal
were available for the use Of war in-
dustries in the manufacture Of the
enormous quantities Of war supplies
needed 70 back up our army and navy,
was rendered possible BY the use Of
dehOcculated graphite. in the drawing
Of Tungsten wire used for incan-
descent lamps.
In the manufacture OF this Tung-
stem wire which is extremely brittle,
Il was found necessary to discover q
lubricant which would lubricate q
hole in a diamond through which
Tungsten wire is drawn. from one TO
eight ten-thousandths OF an inch in
diameter. as oil in its thinnest form
would not pass through these orihces.
The wire in a 14-watt lamp measures
one ten-thousandth OF an inch in de
ameter and ls Approximately one
seventh the size Of a human hair and
when removed from the lamp % near
a A.
when lighted its diameter Is increased
BY its incandescent glow apparently
many times. This difficulty in lubri-
cation was overcome by using dehoc-
culated graphite and distilled water.

Dehocculated graphite combined
with oils Is now coming into extensive I
use in the United States for many pur-
poses, although Il was recognized and !
used for years By many Of the Euro ]

Dehoeculated graphite IS manufac- !
tured from absolutely pure graphite !
Of extreme hneness made In the cleo
trio furnace and subjected TO the enor-
nous heat OF 1900 degrees Fahren- 4

graphite, which IS finer than the finest 4
grains Of flour, is scientifically treated i
BY q special process invented BY DR.. I
Edward g. Acheson, and each grain or
particle Of graphite is dehocculated or
broken up into approximately 1000 or
more molecules.

The great affinity OF this fine
graphite for metals permits IL to en-
ter into the pores and combine with
the metal itself. forming a graphoid
surface by hlling IN the inequalities
Of the metal and coating over all the
high points with its soft unctuous
properties and when used with the
proper lubricating mediums prevents
metal to metal contact, and thus does
away with the majority OF the wear

bearing surfaces.
