Plan Airplane Service to South America

Honduras, Nicaragua, Costa Rica, PAN
anna and thence to Barranquilla, which
is on the north coast of South America.
The New YorkBuen0s Aires route
will go along the coast and over Flor
ida to Key West, whence it will cross
to the West Indies, by way of Cuba,
Porto Rico, Haiti and other islands
1t will touch South America first at
Ciudad Bolivar in Venezuela. Then
the following countries of South Amer
lea will be trayersed: Colombia, Bra
I'll. Peru, Paraguay, Uruguay and Ar
gentina.
In connection with the New York
Buenos Aires route the organizers of
the service point out that natural con-
ditions favor its success. Hydroplanes
will be used. When the machines leave
Key West they sweep around an arc in
the Caribbean sea formed by the West
Indies. The largest distance between
any of these islands is Is miles, an
easy distance.
In South America, even though the
route lies through its center, there viii
always be facilities for easy landing
in hydroplanes.

Combination Tuning
and Grid Condenser

Herein is described combination
tuning and grid condenser which will
save considerable space and at the
same time increase the efficiency of
any receiver in which 1t is used In
structions for building radio sets al
most invariably advise the builder to
use short leads in wiring the instru-
ments. This is particularly true in the
grid circuits. The resistance of leads
six inches or more in length is not
high, but when we take into consider
alton the extremely low voltage in
duced III the secondary circuit, the
value of short leads becomes ap-
parent. In order to avoid body ca
pacity effects, the grid condenser is
usually connected to the stationary
plates of the secondary condenser.
Since the plate of the grid condenser
is connected to the stationary plates,
why not do away with one plate of the
grid condenser entirely and substitute

Electric Lamp for Miners Gains Favor

years later before the safety flame
lamp was introduced. At first coal
was undoubtedly obtained from out
crops, and mining was done by day
light. AS the outcrops were worked
out, the miners advanced gradually
further and further into the coal bed,
until the openings became quite ex-
tensive and somewhat resembled the
small mines of today.
Even the approximate date when
lamps or tallow candles were first used
in mines Is unknown, but some source
of artificial light was probably used in
metal mines long before coal mining
began. Agrieola, in a treatise on metal
mining published In 1856, gives
sketches that show conditions prevail,

Admitting that static is a bugbear TO
radio, 1t knows no fayorite type of set !;
II affects all, but engineers have de-
signed circuits and methods of recep-
ton which at the present stage Of de-
velopment can be termed as highly sat
isfactory means.
One of the greatest steps along these
lines is the development Of the loop
aerial.
But TO get down TO the point of our
talk. 1t has been said that a loop will
pick up but ITO the signal voltage that
could be obtained with the use of an
outdoor aerial. If this Is so 1t is
easily seen that we must increase or
amplify this signal to such value that
1t will operate a detector; the method
OF wiring up and operating a radio
frequency amplifier has been published
IN detail many times, therefore it will
not be given now. Our thought is the
construction of the loop itself. In
laboratories and work accomplished by
the vast number of radio experiment.
ers different types and sizes of loops
have been used, ranging in size from
small coils one inch in diameter, honey
comb coils and receiving coils of vari-
Gus tuners up to massive single-turn
loops measuring 10 feet on side
Best Type of Loop.
Experiments proved that the best
type of loop for use on the broadcast
ing wave lengths measured about 81
feet on q side and consisted of but
single turn of No. IS green and yellow
single conductor lamp cord. This loop
was tuned by means of .0006 variable
low loss condenser and the results ac-
complished by ii fully equaled those
obtained with an outdoor aerial meas
uring 10 feet long.
Owing to its awkward dimensions it
was impractical for home use. There
are, however, smaller and more con-
venient sizes TO handle which will give
very good results.
The illustrations will give the expe-
rimenter an Idea Of types of loops
which can be constructed at very
small cost. Figure l shows the loop
used In the Sleeper Monotrol receiver.
The crosspieces measure 81 inches, or
1914 inches on a side. 1t is wound with
10 turns of standard flexible loop wire
spaced one-half inch apart, the outside
turn measuring IS inches. It is pro-
vided with a set of taps, which are con-
nected to the I'd, 4th. 9th. Sth and 9th
turns. This arrangement, which is
found in no other loop, performs the
unique duty of controlling the potential
The Ely miner. [volume] (Ely, Minn.) 1895-1986, 1924-08-15

on the grid of the first tube, thereby
eliminating the usual potentiometer.
The switch does not vary the induc-
tanCe of the loop. The frequency Is
only varied by the condenser, which Is
shunted across its terminals, the low
er one of which is connected TO the
filament and the upper one to the grid
of the first tube.
Other Kinds of Loops.
Another type of loop. of the pancake
type, which will afford interesting food
for thought is shown in Figure 8. This
loop was experimental with by 81. G..
Silbersdorff of Jersey City, n. j., and
has the added feature of being able to
not only rotate on its axis but can be
tipped TO any desired angle as well.
Experiments with the use of reson-
ance wave coil led up TO the loop in
its present form, and 1t was found to
have certain defined advantages over
the average loop. 1t seems to at least
partly solve the great summer question
of signal TO static ratio. When tipped
at certain angles the static Is weaker
and the signal stronger. The theory
is as follows: If radio waves travel
parallel to the surface of the earth
and static disturbances travel in a
more or less perpendicular path 20 1t
the adjustment of the pickup coil can
he so arranged to pick up most radio
waves, which is at such an angle that
it will pick up a minimum of static
waves.
The crossarms of the l6op measure
IS inches each and the outer frame
work pieces measure 1914 inches each.
Thirteen turns are made, which are
spaced three-eighths of an inch apart.
C-shaped brass angle pieces are
fastened into the Formers of the outer
frame, which serve to support the inner
crossarms. The entire loop is tuned
by means of .001 variable condenser.
Still another form of looi, is shown
in Figure 3. This is known as the box
type and, while IT requires more room
TO set up, is claimed by many en-
gineers TO be more efficient than the
ordinary spiral or fiat pancake loop. A
good size to use for the broadcast
waves measures four feet on the arms,
the ends of which are provided with
bakelite or other insulating material
in the slots on which are wound 10
turns of loop wire, five on either side
of the lower upright support. Like the
other types, it is tuned with a variable
condenser and is recommended highly
for use with supersensitive receiving
instruments, owing to its large dimen-
sions.-New York Evening World.

The introduction of G battery in
the audio frequency ampIifier will
greatly improve the clarity of the OUT
put. This C battery consists of two or
more fiashlight cells, and as there is
very little current drawn from them
the batteries should last between
six and eight months. The C battery
should be interposed between the fla
inent lead OF the transformer and the
negative lead of the A or lighting bat
rery, with the positive post of the G
battery connected with the negative
lead of the filament. The negative side
of the G battery is connected to the

Women's complaints often prove to be
nothing else but kidney trouble, or the

makes the purchase of more than two
or three transformers unnecessary. no
matter how many different receiving
sets the eyperimenter may use
The scheme, as can be seen from
the drawing, consists of mounting the
transformers upon separate, Identical
bases of bakelite or formica on which
four contacts made from switch stop
wired TO the terminals of the trans
formers. If different makes of trans
formers are used. be sure the G b.
and F terminals are wired to cor
responding contacts on the bases TO
prevent reversed connections as the
transformers are moved from socket to
socket.
The sockets consist of pieces of
formica or bakelite cut slightly larger
than the transformer bases. On each
of these are fastened four binding
posts and four "Rasco Societies"
(small siZe). If the Societies can
not be obtained, cord tip jacks which
will accommodate stop pins or the ar
rangement shown in Fig. 2 mays be
used.
To avoid placing the transformers in
the sockets Incorrectly, do not arrange
the contacts in square or rectangular
formation, but place the primary con-
facts closer together than the sec.
ondary contacts.
This idea is also useful in making
comparative tests between different
transformers. and also the best posi-
ton in the circuit for different radio
transformers.

Receivers Should Have
Variable Capacities

In sensitive radio-frequency receiv-
ers of the neutrodyne type it is hard
to neutralize them over their entire
tuning range. They win be neutral
lied as a general rule at about the
middle range, around 800 meters.
When a station is tuned in around
40 meters the naturalization is not
exact, and there is a slight tendency
toward oscillation, causing the receiv-
er to be rather noisy-much the same
as a regenerative receiver just before
splitting over. To be really efficient
these receivers should have variable
capacities, which can be varied with
each and every change in the tuning.

the stationary plates of the secondary
condenser? A simple method of ae-
comprising this is to remove the end
piece of the secondary condenser and
fasten clear piece of mica about 001
inch thick and one inch square TO the
outside stationary plate by means of
shellac. piece of tin or copper foil
may then be placed over the mica TO
form the other plate of the grid con-
denser. This plate may be fastened to

small lug. The grid connection is
made directly to this binding post The
