ENGINEERING REVIEW
A Conventional Arc Furnace Finds a New Use in
        the High Strength Cast Iron Field
  Recently the rocking type, indirect arc furnace has been
adapted to the smelting of iron after having baen used satis-
factorily with non-ferrous alloys for some time. The arc
in this furnace is maintained in the center of a cylindrical
unit, thereby heating the melt in the lower part of the
barrel and the refractory lining above by radiation. By
rocking the furnace back and forth the heat of the lining
is transferred to the metal giving a fairly good heat transfer.
  The reasons for the delay in applying this type of furnace
to ferrous uses were the lack of a suitable refractory for use
with iron and the constantly fluctuating demand for any
one type of high strength cast iron. The high temperatures
required in the modern cast iron manufacturing practices of
from 2950 to as high as 3000 degrees Fahrenheit can now
be resisted by a new refractory of mullite mixed with a
diaspore clay.
Convention of Engineering College Magazines as a
      Link in the Technical Journalism Field
  When the organization of Engineering College Magazines,
Associated, held its annual convention at Rose Polytechnic
Institute in Terre Haute, Indiana, last month, a group of
70 editors and business managers convened and in two days
learned a good deal about this business of publishing an
amateur publication. Inasmuch as the field of teaching
technical journalism is still in the first stages of develop-
ment, the engineering journalist is somewhat handicapped
as compared with the student engaged in publishing daily
periodicals, who is usually a student in a journalism de-
partment.  The discussions at the convention, lead by
Leonard H. Church, McGraw-Hill publication representa-
tive, were for the primary purpose of acquainting the dele-
gates with the methods and means of combining straight-
forward engineering thought with accepted and conventional
editorial and business policies.

  Robley Winfrey, professor
of civil engineering at Iowa
State, and retiring chairman
of the group, conducted the
business sessions at which
Leonard Church was elected
chairman, Professor J. Doland,
University of Illinois, with
Professor R. Beckman, of the
technical journalism staff of
Iowa State, were elected vice-
chairmen of the organization.
  In the annual competition
conducted between the twenty
members of the group, the
Wisconsin Engineer received
two awards. The alumni notes
section was awarded third
place with the Iowa Transit
and the Iowa Engineer carry-
ing off first and second place.
