A simple change in construction
of electric furnaces was said today to
hold promise of extending iron ore
resources Of the United States by
many years.
/ w. B. Wallis Of Pittsburgh described
in q paper read before the Electro
chemical Society how this new type OF
furnace permits the salvaging of old
scrap iron and mill sweepings for
merly discarded because re-melting
of them was too expensive.
The society Is meeting at the VIII
lard Hotel for q three-day convention.
There are 167 members In attendance.
Some concern has been expressed
recently by conservationists over the
amount of iron ore left in this coun-
try's deposits. once believed inexhausti-
BILE. With the use Of steel alloys in
creasing yearly, many were said to
be pessimistic over the outlook. The
new electric furnace offers now, how
ever, Wallis said, possibility for much
more economical use Of the available
supply.

The major point in which it differs
from older types Is in the method Of
charging or putting the metal to be
melted into the furnace, formerly done
laboriously through q door in the
side of the furnace. Instead, the new
model has a top which lifts of and
swings completely to one side. max
ing it possible for machine to dump
the entire charge. ranging from S
to 20 tons, into the furnace in one
operation. A marked saving in time
and power consumption is claimed for
the change.
Stars with an interior temperature
of 1000, 900 900 degrees were discussed
yesterday at the eighty-sixth meeting
of the society in Washington-where
a temperature Of 95 degrees in the
shade is considered something to talk
about.
Energy Is Visible.
In estimating that the gaseous in
teriors OF ordinary stars produced a
temperature of about 2.000, 0,000, 900 de-
grees Fahrenheit, DR.. T. e. Sterne Of
the Harvard College Observatory told
the electrochemists that radiation IS
leaving the stars, or else we should not
see them. So far as is known" he
continued, mo appreciable energy en-
ters q star from outer space. There
must therefore be flow Of energy
from the inside of star toward its
surface. There are good grounds for
believing this energy Is mainly in the
form of radiation, while it is quite GER
tain that the temperature must in
crease as the center Of star is ap-
preached"
The electrochemists also considered
a sun furnace used by DR.. w. M. Cohn
Of Berkeley, Calf, to produce tenn
peratures Of about 5000 degrees
Fahrenheit, and to make an extremely
hard glass called zirconia for use in
kilns and high-temperature furnaces.
DR.. Frank j. Tone of Niagara Falls,
N. Y. president of the Carborundum
Co., was awarded the Edward Good
rich Acheson Medal and a 81 900 prize
at a banquet of the society lest night.
DR.. Tone, father of Franchot Tone,
actor, said he would turn the $1,000
prize back to the society. The Ache
son medal is presented biannually by
the society for the most outstanding
accomplishment in electrochemics.
The presentation was made by
James H. Critchett of New York City
and witnessed by DR.. Tones two sons.
Franchot and Jerry.
