Bell system of controlBell system of control Bell system of control (A["e]ronautics)
See Cloche. cascade tandem or concatenatedCascade system Cascade system (Elec.)
A system or method of connecting and operating two induction
motors so that the primary circuit of one is connected to the
secondary circuit of the other, the primary circuit of the
latter being connected to the source of supply; also, a
system of electric traction in which motors so connected are
employed. The cascade system is also called
tandem, or concatenated, system; the connection a
cascade, tandem, or concatenated, connection, or
a concatenation; and the control of the motors so obtained
a
tandem, or concatenation, control.
Note: In the cascade system of traction the cascade
connection is used for starting and for low speeds up
to half speed. For full speed the short-circuited motor
is cut loose from the other motor and is either left
idle or (commonly) connected direct to the line. Chautauqua system of education

1. (Bot.) Any tree or shrub of the genus Quercus. The oaks
have alternate leaves, often variously lobed, and
staminate flowers in catkins. The fruit is a smooth nut,

recognized about three hundred species, of which nearly
fifty occur in the United States, the rest in Europe,
Asia, and the other parts of North America, a very few
barely reaching the northern parts of South America and
Africa. Many of the oaks form forest trees of grand
proportions and live many centuries. The wood is usually
hard and tough, and provided with conspicuous medullary
rays, forming the silver grain.

of by American type founders, but is substantially correct for
England. Agate, however, is called ruby, in England, where,
also, a size intermediate between nonpareil and minion is
employed, called emerald.
Point system of type bodies (Type Founding), a system
adopted by the type founders of the United States by which
the various sizes of type have been so modified and
changed that each size bears an exact proportional
relation to every other size. The system is a modification
of a French system, and is based on the pica body. This
pica body is divided into twelfths, which are termed
``points,' and every type body consist of a given number
of these points. Many of the type founders indicate the
new sizes of type by the number of points, and the old
names are gradually being done away with. By the point
system type founders cast type of a uniform size and
height, whereas formerly fonts of pica or other type made
by different founders would often vary slightly so that
they could not be used together. There are no type in
actual use corresponding to the smaller theoretical sizes
of the point system. In some cases, as in that of ruby,
the term used designates a different size from that
heretofore so called. Post-mortem examinationPost-mortem Post-mor"tem, a. [L., after death.]
