AIR

One upon time ozone was the
exclusive property OF the summer and
health resort and folk who needed its
health-sIvins Influence had to jour-
ney 20 the sea shore or to the pine
forests OF the mountain districts. So
many marvellous things are now pro-
duced by electricity that We turn na-
turally To this wonderful power
when We need anything new. Aud.
as usual, II is electricity which now
produces ozone bv artificial means.
Ozone can be found In the atmo.
sphere OF certain mountain districts
md at the seaside. and In either
place especially after hard thunder
the ozone remains a long time before
liz finds oyidizablc matter and con.
sumes itself. Ozone ts produced dur
ling u thunder shower by the dis
charge of lightning which breaks
down and icnizes some OF the oXy-
gen In the air. The atoms freed in
this way soon collide with normal
loNygen molecules and form ozone.
lrhus ozone Is n constant purifier or
the atmosphere and II is well that
This is so. for. otherwise. the air
would have long ago been filled with
fhc yapors OF decomposition.
Ozone Is a colorless gas with tho
odor of chlorine when present in
small quantities and smelling OF
phosphorous In strong concentrates.

Grees cent!gradc. II is one OF the
notifications OF oxygen with a chem
heal formula OF OF. II Is n compound
formed by the absorption Of energy.
and in the presence OF oxidixable or
'ganic substances II readily decompcs-
les into oxygen while the third atom
forms more stable compound with
the substance attacked.
How Ozone ID Made
Just rs the lightning flash pro-
duccs ozone 10 has man learned TO
make II with the aid OF electricity.
An artificial lightning discharge or
considerahlc area Is provided by
means OF electrical plates surround
Ing a field under electric STREET
through which mir passes. When the
intensity oi til. electrical charge Oh
the surface Of the plates reaches a
ccrta!n value the electricity will
flow into the air in tiny streams aud
thus impaired will ionize the oxy-
gen molecules. The resultant Ions,
IN turn. become the centcrs Of AZ
Rregatcs of atoms and constitute o.
zone.
While ozone may be aftificially
produced In number of ways the
machines in general use today are
based upon the principle OF passing
air between electrified plates.
Pure air for breathing purposes Is
valuable asset wherever working
men arc employed. 1t Is not always
possible to secure an adequate SUP
ply OF fresh air through ventilation
alone. by purifying the air with
ozone the quantity OF new air re-
1uircd is decreased and the cost Of
ventilation and heating correspond
ingly lowered.
Ozone. when applied in a room.
shop or office. where number OF
people are congrekatcd. purIfies the
air by burning up the animal re.
fuse. waste products and bacteria
which float in the mir in such crowd.
ed places. 1t destroys all odors. by
oxidizing all organic substances.
Therefore. azone Is especially valu-
able for the sterilization and de-
odorization OF the mir In hospitals.
apartment houses. studios. public
school rooms. theatres. department
stores. churches and wherever large
number Of people conEregate. Where
strong odors prevail, as in rag sort
ling establishments. fertilizer factor
les. gelatine and glue works. or In
any other manufacturing places
where hides, hair. fats, bone. horn
and other animal products are used,
Fozone has recognized commercial
value.
In theatres the addition OF an o.
zonator Is Il decided improvement as
well as q safeguard to the public
health. This il also true OF banks.
land business places. For many years
fthe fumes arising from burning gas
es and molten type-metal imperiled
the lives of linotype operators. The
Implication OF ozone oxidizes and
breaks down these poisonous gases.
and for this reason ozonators are
rapidly being Installed In cmposing
and stereotyping rooms. A large
number of other manufacturing
places and work rooms In the indus
trial arts have found ozone beneficial
and helpful.
Electric. ozonatOrs. such as are
fused in households and factories, con-
fsist of step-up transformer which
raises the supply of voltage. whether
alternating or direct current, suffi-
tciently high to stream off the highly
lChargcd mates and thus produce
