for the performance of work; specialized charts, forms and models for determining effi-
cient working procedures and plant layouts. In addition, a large variety of hand tools
and several machine tools including a drill press, band saw, jig saw and bench lathe are
provided to permit the making of labor-saving jigs and fixtures, plant layout models
etc., and to provide operation set-up to be analyzed by time and motion study. Visual
aid equipment includes conventional 8- and 16-mm. silent projectors, a 16-mm. sound
projector and an opaque projector.

 MECHANICAL ENGINEERING LABORATORIES
 Mechanical engineers are employed in the development, design, manufacturing,
and application of all types of machinery. The laboratories are designed to give the
student first hand knowledge of the engineering principles, processes, and equipment
studied in the classroom. Laboratory work supplements classroom study and presents
in a better way those things which are vital to an engineer's training.
 The principal objectives of laboratory training are: (1) To teach the student the
proper selection and use of instruments in connection with problems of research, design,
and testing; (2) To acquaint the student with a wide range of equipment such as air
conditioners, turbines, jet engines, and many other types used today; (3) To train the
student in the preparation of engineering reports so as to give him greater command
of written English.
 The Manufacturing Operations Laboratory comprises a wide selection of modern
machine tools including automatic lathes, milling machines, shapers, belt and disc
grinders, contour saws, filing saws, and a pantograph. Precision testing and inspection
equipment is studied including X-ray, magna-flux, optical comparators, Johansson gage
blocks, and super-micrometers.
 The Welding and Heat Treating Laboratories give the student actual experience
with both alternating current and direct current electric welders, spot welders, atomic
hydrogen arc welding and various types of flame welding and cutting methods, includ-
ing automatic cutting machines. The deposition of metal by means of the metal spray
gun is also included. Many types of electric and gas fired heat treating furnaces are
available including those with controlled inert gas atmospheres.
 The Metallography Laboratory has very complete equipment for studying the in-
ternal crystal structure of metals. Several metallurgical microscopes with camera equip-
ment are used by students to photograph the crystal structure of a wide range of
metals. Suitable polishing, etching, and chemical identification laboratories are avail-
able for this work. Dark rooms are provided for developing pictures made of metal
structure.
 The Steam Power Laboratory includes a complete steam generating station with
boiler, turbines, engines, condenser, cooling tower, pumps, and the necessary specialized
instruments for testing all these devices. An integral part of this laboratory is the fuels
testing laboratory where the student determines the chemical and physical properties
of fuels and also the control tests required for boiler water.
 The Internal Combustion Engine Laboratory includes a wide range of automobile,
aviation, and diesel engines. Electric and hydraulic dynamometers are provided for
testing engines with speeds as high as 6000 revolutions per minute. The laboratory
equipment includes a turbo-jet engine, and a special experimental aircraft engine being
tested in cooperation with the Army Air Force. High speed engine indicators for show-
ing gas behavior inside of aviation and automobile engine cylinders are -used in con-
nection with research in this field.
