Interesting Lectures at Carnegie Tech
Two distinguished European scientists and five
prominent American chemical engineers were included
on the program of free public lectures during April
and May of this year at the Carnegie Institute of
Technology in Pittsburgh. All of the lectures, an announcement
points out, were arranged in connection
with the policy of the institution to encourage a greater
interest in scientific research among Pittsburgh
District engineers and scientists.
As a special service to the scientists of the district,
the lectures were scheduled for presentation evenings
to permit many engaged during the day to attend the
discussions.
The first of the series was given on April 15 by
Dr. Franz Fischer, Director of the Institute for Coal
Research at Mulheim-Ruhr, Germany, who lectured
on "Liquid Fuels from Water Gas." The other prominent
European scientist included in the series was
Dr. R. V. Wheeler. Professor of Fuel Technology at
the University of Sheffield, and Director of the Mines
Department Experimental Station of Great Britain,
who was scheduled to give a series of two lectures
April 22 and 23 on "Constitution and Origin of Coal"
and "The Relation of Constitution and Origin of Coal
to Practical Problems in Mining, Storage, and Utilization."
Both the Fischer and Wheeler series were
given in co-operation with the Pittsburgh Experiment
Station of the United States Bureau of Mines.
Other lectures during April and May comprised a
second annual series on chemical engineering problems
given under the joint auspices of Carnegie Institute
of Technology and the Association of Chemical
Equipment Manufacturers. This series, it is announced,
was arranged primarily for chemists and
chemical engineers in the Pittsburgh District, although
open to any one interested.
The schedule for this series follows:
April 17, "The Importance to Industry of Properly-
Designed Chemical Equipment," by G. O. Carter,
Consulting Engineer, Linde Air Products Company.
April 21, "The Role of Chromium Alloys in Chemical
Plant Apparatus," by C. E. McQuigg, Metallurgical
Engineer, Union Carbide and Carbon Research
Laboratory.
May 8, "Continuous Processes in the Chemical Industry,''
by J. A. Baker, Engineer, the Dorr Company.
May 13, "The Equipment Manufacturer and His
New Relations to the Chemical Industry." by Dr. K.
C. Parmelee, editor of "Chemical and Metallurgical
Engineering.
May 22, "Art in Filtration" by Charles Fuhrneister,
Jr., Oliver Continuous Filter Company.
To Install Induction Furnace
The Hoskins Manufacturing Company, now using
two electric induction furnaces in the production of
chromel and similar alloys, recently ordered a third
electric unit for installation with the others in the
Hoskins plant in Detroit. These furnaces have been
found valuable in working to the close analysis necessary
in such manufacture, and the Hoskins Manufacturing
Company has obtained excellent results with
May, 1925
the existing installation in producing metals of extreme
uniformity with every heat.
The two original furnaces are of General Electric
manufacture and the third, now on order, will be of
the latest type with the winding located above the
bath and cooled by air blast. The furnace will be
tilted on trunnions by a handwheel in the usual manner.
The new unit will have a holding capacity of 650
pounds of metal, and each pour will be about 400
pounds. It will be rated 100 kilowatts and will operate
directly from the city power lines through a singlephase
transformer which will step down the voltage to
440 volts, 60 cycles. Power regulation will be obtained
by means of taps in the transformer and an induction
regulator.
Open Hearth Committee
Steel works executives and open hearth superintendents
representing 22 companies in the Middle
West, the East and the South, attended a conference
at the William Penn Hotel, Pittsburgh, April 15 and
16, and formed an open hearth committee for the exchange
of operating ideas, standardization of furnaces,
practices and of materials.
J. V W. Reynders, president of the American Institute
of Mining and Metallurgical Engineers, presided
at the conference, and L. B. Lindemuth, of the
consulting engineering firm of Carney & Lindemuth,
New York, who is secretary of the iron and steel
section of the institute, was secretary. Another conference
will be held in about six months, and every
six months thereafter. A general committee composed
of E. A. Witworth, Bourne-Fuller Company,
Cleveland; W. A. Maxwell, Inland Steel Company,
Chicago; L. F Reinartz, American Rolling Mill Company,
Middletown, Ohio; A. R. Maxwell, Pittsburgh
Steel Company, Pittsburgh; A. W. Smith, Youngstown
Sheet & Tube Company, Youngstown, and L.
B. Lindemuth, Carney & Lindemuth, New York,
will conduct the affairs of the new organization.
Papers were presented by L. B. Lindemuth on
"Furnace Operation;" by R. S. Poister, Norristown,
N. J., on "Pit Practice;" by L. F. Reinartz, on "Open
Hearth Fuels," and by C. H. Hunt, Weirton Steel
Company, Weirton, W. Va., on "Furnace Construction."
Mr. H. C. Thomas, Alan Wood Iron & Steel
Company, Philadelphia, and A. R. Maxwell, Pittsburgh
Steel Company, as well as Mr. Reynders, spoke
on the advantages of the movement.
