WhatJ)e Wc Mean
It la always a stlrprlse te a I'haftl I'haftl
belled liaiii," as they call an old-time
radio operator.) te talk te n layman,
using the most familiar' terms of. wire
less and then suddenly find nls listener
doesn't knew what he mcAns. ' ''Yeu
don't knew what si 'tapped roll' Is?
,wny, a tapped con. is myn coil tnat
Is tapped., Kvcryb6dy knews: that."
But he finds' that everybody doesn't
knew. It. nut a tapped roll Is really
n verf simple piece of apparatus and,
as'lt Is used in virtually every recelv
Ing'set. let's spend a few minutes ex
amining one. ' tn '
But first let's forget wireless and
think of 'ordinary plumbing. 'Ypu've all
seen these cells 'of water pipe' that. go
V . TANK
n
e ie ae 30 4e
RECEIVING
TANK
.
OKOUMD
This dlngrnm represents a cell of
pipe In a water heating apparatus.
There are supposed te be spigots
en each pipe at the supply tank
and also en each pipe at the receiv
ing tank. The accompanying
.article explains Its similarity te a
cell In radio
Inte modern heatlng systems for the
rapid heating 6f water. The mere pipe
surface you expose; te -the flames, the
mere het water you will get.
Our illustration shows such a heal
ing cell its It might have been built
by a man with the nightmare. Suppose
we have such a coil, with flames all
about it but. with different pipes run
ning from the supply tank te different
turns of the roll and different ether
pipes taking the water from different
ether turns of the pipe and delivering
It te the receiving tank, which may
be considered the' rest of thp heating
system. ' Remember that there" are
flames all around the whole cell and.
every' square Inch of Its surface Is
heated.
Yeu 'sec spigots en nil the pipes from
the supply tank and all emptying into
the receiving tank.
New, Mipiwsc wc open spigot
marked "0" from the supply tank and
the spigot marked "O" te the receiv
ing tank. Obviously, we aren't going
te get any het water, for the water is
going te run straight from the upper
tank te the lower because the two "O"
spigots arc directly connected by pipe.
But (assuming the cell pipe Is always
full of water), suppose wc open supply
spigot Ne. 0 nnd receiving spigot Ne.
10. Then, following the pipe connec
tions', wc find that the water will run
through ten turiiw -of the het coil and
be heated as much as these ten turns
ran heat It. If wc want it n little
hotter, wc can use supply spigot Ne. 5
and receiving spigot Ne. 10 and then
wc will get the heating effect from fifteen
turns of the cell.
If wclitive ten supply spigots, num
bered from 0 te 0. and eleven receiving
Mdgets, numbered from 0 by tens te
100, with the two 0 pipes connected,
we can get any lientlng effect from zero
te 100 turns.
New, that's nil n "lapped .coil" in
radle.is. The electricity. Is the water,
the wire is the piping nnd. Instead of
getting heat from the cell. wc get cer
tain electrical effects which give us
greater or less wave length. .The .mere
turns of cell wc use Tn the pipes, the
greater the heat : the mere turns of
wire we include in the radio coil, the
greater the wave length wc tune te.
The supply tnnk In the. illustration
is the lrndlng-Iii wire from your aerial.
The supply spiggets are the "unit"
switch points numbered from 0 te 0.
The receiving tank Is your ground wire
nnd the receiving npigets nre your
''tens" switch-points .numbered from
0 te 100.
On an ordinary amateur aerial with
nn ordinary cylindrical coil,-you will
use. something like twenty or thirty
turns te get 200 meters nnd the whole
100 turns "ought, te give you close te
1000 meter". The broadcast concerts
ought (e conic In somewhere around
fifty or sixty. Of course, this Is only
giiPSMvnrk. ns length, lieight, number
of wires, length of lead-in nnd ground
nnd local conditions vary the natural
ware length of any adjustment. But
It will give you nn idea of what te
expect.
.Moving the "lens" switch will
iiuully let you henr the signal mere or
less faintly. Yeu tune your secondary
by changing coupling and condenser
until you get best response nnd then
try moving the unit switch efthe tapped
cell te sec if you can still further im
prove It.
Tn the next article, we'll see hew
easy it Is te wind and tnp such coils
ns this.
