260 COLLEGE OF ENGINEERING

since the technique of an industry can best be acquired in subsequent prac-
tice. The purpose of the course is to offer instruction in those fundamental
subjects which are essential to the chemical engineer in whatever line he
may follow.

EQUIPMENT

All of the Chemical Engineering Building is devoted to the laboratories,
classrooms and offices of the Department of Chemical Engineering. The
building, 75 feet wide by 125 feet long, comprises a high basement and two
floors with a commodious attic.

GAS AND FUEL LABORATORY. Bomb calorimeters of various types are
available for testing the heating values of coal and oil; gas calorimeters
together with the necessary meters, scales, and water tanks are also pro-
vided. The equipment for gas analysis, for testing of lubricating and road
oils, and for distillation of petroleum products is complete.

PYROMETRY LABORATORY. The pyrometric laboratory is well supplied
with base metal and platinum thermocouples, resistance thermometers, and
optical and radiation pyrometers for the measurement of high and low tem-
peratures. The equipment includes precision potentiometers and Wheat-
stone bridges for highly accurate measurements. The furnaces are electri-
cally heated and for accurate control there is an ample number of trans-
formers and reactance coils. The facilities are well adapted for instruction
in temperature control and measurements under industrial conditions.

METALLOGRAPHY LABORATORY. Besides the general laboratory for pre-
paring the metal specimens for microscopic examination, there is a photo-
graphic dark room for developing negatives and making prints. The micro-
scopes for student use are of a high grade and are provided with attach-
ments for photographing; for research there are larger microscopes capable
of high magnification. Accessory apparatus such as furnaces for heat
treatment, pyrometers, polishing apparatus, and quenching devices are also
provided.

CHEMICAL Factory LABORATORY. About one-half of the basement is
devoted to chemical manufacture and tests on machinery. A complete labo-
ratory with balance room on the first floor is provided for chemical analy-
sis. Among the important pieces of apparatus are: two rectifying stills
each of 20 gallons capacity, three plain oil stills of 10 to 15 gallons capacity,
3 filter presses, a single effect vacuum evaporator, a vacuum drying oven,
pressure digester, two hydraulic presses, one of 40 tons maximum pressure,
an autoclave of 5 gallons capacity, and crushing and grinding machinery.
Besides these there are the necessary wooden, metal and stoneware tanks,
basket centrifugal machine, drying oven, furnaces of the muffle, crucible,
and reverberatory type, and other desirable appliances to conduct experi-
ments on a semi-factory scale.

ELECTROCHEMISTRY LABORATORY. The general laboratory for electro-
chemistry is well equipped with tanks, stirring devices, indicating and re-
cording ammeters and voltmeters, instruments for measuring resistances.
Fither alternating or direct current is available at the desk of each student.

For instruction in electroplating, refining and electrotyping, the equip-
ment comprises polishing lathes, a motor dynamo, and a storage battery.
