IN such position that 1t can be
readily observed during operation.
The panel Is of best grade bakelIte.
and all insulation has low dielectric
loss. This makes for increased sig

A LOOP FOR THE RADIO RECEIVER

Loop antennae will probably solve
lot of problems connected with the re-
ception of radiophone broadcasts. At
any rate, very large number Of ex-
perimenters and others are using them
to good advantage 1t must be always
understood. however, that loops will not
allow of the same production of sound
volume IN the telephone receivers as
outside antcnnae. unless very special
receiving equipment is used.
The loop is very small. only six inches
square and ore-half an inch thick. II
can be pat inside of cabinet $" that
which forms the loop proper is mounted
upon a mahogany finished wood frame.
\ top and bottom piece of ballelite pro-
vide covers which protect the loop.
Binding posts. which have bakelite tops,
are provided for connecting the loop in
various ways into receiving circuit.
The inductance of the loop in use for
the particular wave length 10 he re-
ceived can be varied by changing the
circuit connections to the binding posts.
sufficient taps being taken from the
coil for this purpose
For best results with such a loop two
or three stages of radio frequency am
pliticaticn should be used. and the out
put of the last radio frequency stage
fed into the grid circuit of detector
tube. The output circuit of this de-
tector may be coupled TO the input cir

ELECTRON THEORY OF ELECTRIC
CURRENT

In all materials regarded as good
conductors of electricity there are
presumed to be minute negative
charges which are not very closely
associated with or bound" to the
atoms of the substance. They are
called free. and move with some We
focity from one atom to another IN
every direction between atoms. Even
In a very hard metal the atoms are
not thought of by scientists as being
crowded so closely together but
what there is space between them
that is, even a very hard substance
is spongy, to some extent. These
free electrons might be compared. as
they have been, to the comets of our
solar system.
The molecules of compound, the
atoms of an element and the eiec-
irons are all regarded as beng IN
constant motion, the motion beng
less hindered in gases and liquids
than in solid substances. suppose
that the steam which rises from a
pan of water heated over a hre IS
considered The steam is. of course.
produced by heating the water. and
If We admit that the motion OF the
molecules and atoms can be speeded
up by increasing temperature. 1t is
not difficult to imagine that the mole
cules might gain sufficient velocity to
fiy up into the air. 1t is only step
TO imagine that even the normal
evaporation of water might be due to
molecules which have been so
speeded up as to fly upward from the
surface of the water. Under certain
conditions electrons may be evapo-
rated in a similar manner from free
electrons. 1t can be easily proven
that II these evaporated electrons
pass through a vacuum from one
electrode to another current of
electricity flows between the two
electrodes. This seems to prove that
a flow or drift of electrons from one
point to another is what constitutes
an electric current.
If at one end of a copper wire n
force produces concentration of
electronS so that there are more
than at the other end. there will be
q drift of electrons tending to equal
4ze the number of electrons dis
tributed all along the wire. Such a
force can be created by the action of
an acid upon a zinc plate. If the
plate is connected through a copper
wire back to the acid the electronS
which accumulate on the plate flow
along the wire back to the acid to
take the place of those lost by the
acid. If the action is continued there
Is continuous flow of electronS
through the wire, and we have what
is known as an electric current.
1t is thus seen that an electric cur
rent, either in a conducting wire (or
other conductor) or through a
vacuum, is really a flow or drift of
electrons.

STOCK Quotations

Radiophone Being Used for
Many Purposes in the
Netherlands.

The government of the Netherlands
is now broadcasting weather reports
by radio telegraph twice daily, but is
planning the installation of radio
telephony service In order that farm
ers who do not know code can
listen in.
Every fifteen minutes the Amster-
dam Stock Exchange sends out bulle-
tins by means of wireless telephony
giving the ruling quotations of the
exchange. When the exchange is
closed press bureau makes use Of

illustration shows the same set wired
for vario-coupler with a tapped prim-
airy or stator coil using ten and unit
taps already described.
III using any of these sets, tuning is
accomplished exactly as described for
the single circuit set except that the
movable secondary should be about half
withdrawn from the primary coil. You
should secure the best possible adjust
ment of the taps and sliders. and it
must be carefully moved out or in un-
til the best results are obtained.
To Use Vario-COupler.
If the vario coupler is used, proceed
i'll the same way, starting with the
switches as described and with the rotor
or secondary coil at zero, or in series
with the primary. Get your final ad-
justment by rotating this slowly and
carefully. until the signals come in as
loudly and clearly as possible.
In using any of these vacuum tube
sets. it is advisable TO employ
forty-five-volt "B" battery for the
plate with tap or connection
which will enable you to use
volts of the battery at a time. BY using
first one portion and then the other.
your battery Will give much better and
longer service, for while you are using
one part the rest will recuperate to a
large extent. If you use smaller bat
terry constantly, you will repidly eX-
haust it if you use your set each day
or for long time at a stretch. But be
careful and do not use the full forty
five volts.

BY A. HYATT VERRILL.

Just as double circuit crystal de-
tector sets give better results and af
ford finer adjustments than the single
circuit sets. so, with~a tube set, the
double circuit type is more efficient
There are many reasons for this
In the first place, an induced current,
or in other words the current formed
IN the secondary coil by the passage
OF a current through the primay coil,
is stronger or more intense than the
primary current. In the second place,
by having adjustments or varying
devices upon both the primary and
secondary, much closer and finer tuning
may be obtained.
In making double circuit tube set
either loose-coupled coils with slid
crs on the primary and taps on the
secondary: taps on both primary and
secondary: taps on the primary and
IT. adjustments on the secondary or
siiders on the primary and no vari-
able adjustments on the secondary
may be used. In fact. it is not even
absolutely necessary to have 4 NOV
able secondary coil, but this is highly
desirable to give proper variations
in adjustment. You should bear in
mind that the more adjustments you
have. the more troublesome it is to
tune your set, but of course You get
better results.
Advantage of Nario-COupier.
In place of a loose coupled coil, you
may use a vario-couplcr coil. if you
prefer. This may be made either with
a tapped or slider primary. The only
advantage of Tarlo-cOupier over an
ordinary loose coupler is that by re-
volving the rotor or secondary almost
any variation in induCtance may be
secured with one adjustment. BY thus
turning the secondary il may be set
with. against or at any point be-
tween, the direction Of the primary
winding with the result that II may
receive a fun induced current. :. por-
tion of it or may buck" against sud
thus repel it. Many beginners have
an idea that any tube set is a :e-
gene-atiVe" set and others think that
every double circuit is regeneratlve.
AS n matter of fact. there is a very
great difference between either an
ordinary single circuit or a do Iole
circuit tube set and a regeneralive
set.
In the first Illustration. We show a
simple double circuit tube set using a
loose-coupled coil with two sliders on
the primary and a tapped secondary
