various standard controllers that are manufactured for railway service,
with special reference to the operating conditions for which each type
is suited. Among the controllers described are Type B, which include
the necessary contacts and connections for electric braking, Type K for
series parallel operation of the motors, Type L, also in the series
parallel class, but which completely open the power circuit when changing
from series to parallel; Type R, which are designed to control the
motor speeds by means of resistance only, and a brief outline of the
Sprague-General Electric Type M control system. The General Electric CQ
motor is described in detail in a 16-page bulletin. This motor is for
direct-current circuits, and is made up to 20-horsepower in size, and for
voltages, of 115, 230 and 550. The application of the motor to linotype
equipments, ventilating outfits, machine tools, etc., is also outlined.
The extensive tables of dimensions, capacities, etc., in the bulletin,
will be found very useful in preparing specifications.
