The greatest advances made in the
past few years in the radio art have
be^n due in one way or another to
the use of vacuum tubes. In view of
this fact a more careful consideration
of them will be of interest.
All of these tubes, known by a va-
riety of names, such as railiotron, au-
dion, seriotron (trade names of the
manufacturer) -depend upon the same
fundamental principles for their op­
eration. For the sake of simplicity
of brevity these will be referred to in
this column simply as vacuum tubes.
A vacuum tube can be made to func­
tion as a detector, as an amplifier, or
as an oscillator.
The vacuum tube depends on the
emission and control of electrons for
its operation. The electron is the
smallest subdivision of mutter which
mankind recognizes and It carries the
smallest known charge of negative
electricity.
For years previous to
electron research it had been held by
scientists that matter was built up of
distinct particles or units which they
called atoms and molecules. At first
the molecule was assumed to be the
smallest quantity of matter that could [
have a separate existence or take
part in chenfical action, but more vig­
orous research pointed to the fact that
the molecule Is made up of still small­
er elements which are termed atoms;
that is, a molecule may be composed
of several atoms. Then for a time it
was assumed that the atom was the
very smallest quantity of an element
that could exist, but later researches
have revealed that atoms may be

side connected to the filament lead

through the current meter, the plate
becomes electrically positive with re­
spect to the lllainent.
Since like charges repel and unlike
charges attract, there will tie a move­
ment of electrons from the lllainent
to the positively charged plate, and
the current meter will show a deflec­
tion which Indicates that a current Is

ADVICE FOR AMATEURS.
The voltages applied to the
plnte circuits of amplifying
tubes are not extremely critical
and one voltage control will suf­
fice. The detector tube, how­
ever, Is often very critical and
an efficient potentiometer will
work wonders In controlling it.
