    Navy Liberal
With Licenses
More Consideration to Be
Given to Experimenters
Than Radio Sellers.
Washington, Dee. it.—Practically
•very applicant for license to manu
facture radio sets under the Von
Bronk-Schloemilch reflex patent who
owns a patent under which a cross
license can be granted to the Navy
Department will receive one.
It le the plan of the navy to pur
sue a very liberal course In granting
licensee'under the radio patents. It
is estimated that in the neighborhood
of 115 applications have been received
by the navy for licenses.
One of the factors to be taken Into
consideration In granting licenses 1*
tho extent of experimental work be
0ft* ing dona by the applicant. In other
words, an applicant who maintains a
laboratory and Is actively engaged In
promoting the art will receive more
consideration than one who Is merely
engaged In manufacturing and selling
■ets for profit.
There are two outstanding facts In
connection with the applications for
licenses under the navy radio pat
ent!. One Is that within a very short
time ft large number of new reflex
sets may appear on the market. The
other Is that there is ft tendency on
the pgrt of automobile manufacturers
to enter the radio field. Several ap
plications have been received from
this class stating a desire to manu
facture radio eets.
It Is believed that a month or two
will be required before licenses are
granted.
Protector for Tubes.
To protect expensive vacuum tubes
from burning out place a 15 or 20
watt electric lamp of the common
110-volt type In series with the "B”
battery, so that the current must
pass through the lamp before going
to the set. This will protect the tubes
In case of a short circuit.
Loop Turn Spacer.
A hard-rubber comb If mounted at
the ends of the loop frame makes an
excellent wire spacer and holder. If
only a few turns are to be used then
place the wire In every other slot,
to give the loop as large a surface
PM ss possible.
Proper Method of Soldering.
The proper way to use old solder
Is to first make the Joint as tight as
possible and then use a minimum of
solder to hold the Joint together.

Hoyt’s System of Signal Augmentation Graphically
Explained; All Necessary Accessories Contained
B> A. J. FARAON.
All who are familiar with Arm
strong's system of regeneration know
that there are several methods of ac
complishing this result; for Illustra
tion, by the tickler feed back arrange
ment, or by the well known tuned
plate circuit, employing a variometer
or tuned Impedance In the plate cir
cuit of the tube. This same condi
tion applies to the augmentation.
A commercial application of tlie I
necessary accessories self-contained,
reiver Is incorporated in the layout
There are several methods of accom
plishing the desired results. This
must not be taken to mean, however,
that the plat circuit can be tuned or
that a variometer may be employed.
The statement Implies that there srf
other methods by which augmentation
may be secured through circuit ar
rangements differing from the funda
mental circuit of last week. These
circuit arrangements constitute the
basis of ons of the patent applica
tions on signal augmentation as de
veloped by Mr. Hoyt, and will be ex
plained In pext week's Issue.
Commercial Adaptation.
The fundamental circuit shown In
last week's Issue of this paper, while
constituting the basis of all of the
augmentation circuits. Is only the
stepping stone to wider and more
economical applications of this prin
ciple.
The two tubes employed • In the
fundamental circuit nfforded the
equipment of a detector and a radio
frequency amplifier (although more
efficient than the conventional stage
of radio frequency amplification). The
circuit which Is about to be shown
and described goes the circuit of last
week on# better, In that the radio fre
quency or augmentation tube la now
the first stage of audio frequency as
well. This may be taken to be re
flexing—perhaps Ills—but here again
there Is something to analyze, and,
above alt else, certainly food for
thought.
By the circuit arrangement Illustrat
ed In fig. 2 efficiency and economy to j
the nth degree have been attained.
A careful study of this figure, which
has been made in schematic, form to
facilitate er.se of analysis, will be of
value to those who are either interest
ed in this circuit from a technical
point of view or to those who con
template building and experimenting
with the circuit when the turn ratios
and various circuit constants are ex
plained next week.
In Fig. 2 an alternating source of

current aupply has been shown con
nected to the aperiodic primary P.
and the secondaries I,A and L.D are
shown connected respectively to the
grids of the augmentation and de
tector tubes. In the grid circuit of
the augmentation tube the secondary
S of the audio frequency transformer
—around which the by-pass condens
er BP Is bridged—has been Intro
duced. This automatically becomes
the first stage of audio frequency am
plification, as well. The primary of
the audio transformer. Ah', is now
included in the plate circuit of the
detector tube in the position occu
pied by the headphones in the funda
mental circuit. The plate circuit of
the augmentation, or booster, tube in
cludes the augmentation coil, as well
as the headphones or what may he
more properly termed the continua
tion of the audio frequency circuit.
In the augmentation circuit out
lined above several of the values are
critical, and the experimenter Is
warned against final determinations
unt|l the complete data ara aupplled
In these columns.
“K" Circuit.
Mr. Hoyt has "dubbed” the clrenlt
shown In Fig. 2 the "S” circuit, be
cause of the resemblance of the path
of the audio frequency currents
through the duplex tube arrange
ments to the letter 8.
By pass condensers must be used,
as shown In this circuit, each around
the secondary of the audio trans
former and the headphones or audio
cirrult of the augmentation tub*
] These eondensers are necessary to
j operation because radio frequency
[currents flow in both of these
branches. A condenser Is not npees
smry around the primary of the
first audio transformer In the aver
age Instance, although with some
makes of transformers a condenser
of very low capsrltance Improves
operation.
Fig. 3 shows the progressive paths
of the radio and audio frequency
currents In the two tubes. Here the
reference nliovo to the letter "8" lg
apparent. In thin Illustration the In
coming radio frequency energy to

(irltl I<rnIt Important.
Willi the augmentation circuit a
rather nnstinl condition prevails so
far ns lube biasing Is concerned. For
best operation it Is desirable to worli
the augmentation tubs with a nega
live hiss, whereas for detection the
action of the average vacuum tube
Is about twice as good when a posi
tive bias Is applied to the grid. Now,
since tit" Junction of the secondaries
constitutes the grid return circuit of
both tubes. It Is not possible to make
this both positive negative. This
junction Is, therefore, made to the
negative side of the filament and sup
plies the right bias for the operation
of the augmentation tube, while the
grid leak is connected from the posi
tive side of the filament to the grid
of the tube, between the grid terminal
and the grid condenser. In this way
the grid leak acts as leak and biasing
means simultaneously.
From the foregoing paragraph It
will be seen that complications set
In. and an explanation of the theory
Invotved will perhaps not be amiss at
this time. It has been said above
that the detecting qualities of the av
erage tube are about twice ns good
as when a positive bias la applied to
the grid: this comes as a result of the
grid-voltage grid-current curve of the
vacuum tube; that is, as a result of
the shape of thie curve.
Correct Orld Values.
Some one has said that the correct
values for the grid condenser end
grid leak with modern tubes comes
with the product of the capcitance In
micromicrofarads and the resistance
Jn millions of ohms- equals approxi
mately 200. This statement seems
to be about right In practice, while
an examination of the scientific
theory of a vacuum tube shows that
It Is desirable to use as high a value
of each as possible.
As was said before, in tha augmen
tation circuit ' a peculiar condition
exists. This Is due to the fact that
commercial grid condensers have a
certain Inherent leak value, that Is,
they have a certain definite unavoid
able ohmic resistance. This Is seen
from the fact that any receiver will
work (to a greater or lesser degree)
with tlie grid leak removed. If the
grid condenser did not have direct
leakabe resistance it would be im
possible for the receiver to function,
as there would* be no path for the
accumulated electrons on the grid of
the tube to leak off to the filament
and the grid would he maintained at
a negative poential as a result. Now,
since commercial grid condensers do
posses a leak value, we must con

frequently have a blaa applied to the
grid of the tube through thia con
denser resistance. This brings us
to the situation where we have a pair
of resistances In parllel, aa will be
aeen from Klg. 4. In addition we
have two biasing sources to the de-'
lector tube grid, one positive and
the other negative. This is not a
serious condition by any means, but
one which requires attention.
Variable leak Necessary.
The manufacturer of sets employing
this circuit can readily select the^
proper grid leak value for any given
set, and for this value a fixed leak
may bo employed. But In the case of
the experimenter and the Individual
constructor It Is highly desirable that
a variable grid leak (an accurate one!
of at least six megohms range be
used with this circuit. Varloue grid
leaks wers used In early experimenta
tion on thta receher and leak values
of varying magnitude tried. The final
determinations showed that a grid
leak of from five to six megohms was
about right with a grid condenser of
reliability. A variable Fllko-Leak of
six megohms rating covered all of the
requirement* for existing commercial
mica condensers of reliable make.
For the purpose of concrete Illus
tration, let us imagine that the oh
mic resistance of the grid condenser
is the arbitrary value of two meg
ohms and that a variable leak rang
ing from one to six megohms is used
on the grid of the tube. These two
resistances are In parallel and con
sequently follow the law for parallt!
circuits, therefore we have actual re
sistance values of from .63 2 3 meg
ohm to 1-1-2 megohms, considering
the variable leak as operating from
one to six.
Interesting Receiver.
A new and unique receiver and the
first of Its kind and first for Its ex
clusive purpose (to make Its com
mercial bow in the near future) Is
shown In the photograph Fig. 1.
This receiver utilizes the ‘‘S’’ aug
mentation circuit with an additional
stage of audio fre<tueney amplifica
tion. making In all a three tube set.
This receiver has been designed ex
clusively for the business office—for
the business executive, if you wish.
The batteries are self-contained
and for local use the receiver gives
excellent results on a loop. An ex
tremely Interesting feature Is the
sound box and reproducing unit which
srs Included In the top or cover of
the set. The action of raising this
cover turns the set on. Lowering It
turns the receiver off. The volume
from the small loud speaker Is just
pleasant for office use. and the po
sition of the speaker Is at just the
right height for sound projection for
a person seated at a desk.
Market quotations, sporting svents
and a hundred and one features of
Interest to the executive conilned to
the office are thus made Immediately
available to him and it is possible
that the advent of this type of re
ceiver may be the forerunner of a
more comprehensive business broad
casting service.
The complete clrcuita of this re
ceiver, as well as constructional de
tails on features of the augmenta
tion circuit will be explained in next
week's article on this sensational
new circuit.

OCEAN LINER HAS
PASSENGER RADIO
The Canadian Pacific liner Mont
clare is the first steamer to be fitted
up with a ship's orchestral repeater
which will enable music played in a
salon to be heard in other parts of
the ship. On its last trip out from
Liverpool the Montclare had installed
a microphone transmitter, and music
played in the lounge was successfully
transmitted to other common rooms
in various parts of the ship. With
the aid of the transmitter ocean
travel can be made much more pleas

RADIOS DIFFER
SEASON TO SEASON
A receiving set will not act pre
cisely the same on any two days or
nights. ,Messages are received better
after dark than in the daytime, be
cause radio waves do not travel ao
strongly by daylight as they do by
dark. In general, better reception
occurred during cooler mtfnths than
during the warmer ones. This is tie
cause atmospheric conditions pecu
liar to the seasons have a marked
effect upon radio waves. It is con
stant variation In atmospheric condi
tions that make radio .reception also
vary from night to night. The more
favorable the atmospheric conditions
the better the reception.
JAPS REMOVE BAN
ON BROADCASTING
Announcement ha* been made by
the Japanese government that the
ban on radio broadcasting had been
lifted, and that radio broadcasting and
receiving were permitted on the part
of the general public without govern
ment interference after that date.

Interchanging Tube?.
A set that Is equipped with three
or more tubes will work better if
the tubes are changed from one
socket to another. The amplification
factor of a given type of tube 1*
generally said to be the same for
all tubes of this type, but actually
the amplification factor, like other In
dividual characteristics of a tube,
varies -slightly for each tube.
Recharging Dry Cell?.
Dead dry cells can sometimes be
recharged by boring two holes tn the
top of the cell, on opposite side of,
the center connections, each one-quar

Pawnee City, Dec. 26.—Payment in
full of the 1924 tastes assessed against
the defunct K. C. N. W. railroad by
the receiver of the road is bringing
heart to residents of the southwest
part of Pawnee county. For many
years the road has not been used.
In tendering the check of $2,231.41
to the county treasurer, the repre
sentative of the company stated that
conditions appeared bright, and that
probably with a federal loan the roaid
might again operate. Tax claims by.,
Wyandotte county, Kan., are being
argued by the officials, and their set
tlement has not yet been announced- .

CHESS MATCH IS
PLAYED BY RADIO
Haverford. Pa., Dec. 2S.—For fiv-»
and one-half hours a group of stu
dents at Haverford college recently
sat before several tables moving
chess men in accordant with the in
structions shouted st th-m by a radio
operator in the next ream. At the
same time, another group of stu
dents of Oxford university. England,
3.000 miles distant, were making the
identical moves and discussing the
same point. ‘
The instructions from both teams
were being sent in dots and dashes:
the first international chess match by
amateur radio was being played. The
game, which started at 7:15 p. m..
eastern standard time, was carried
on without a halt until 12:45 the next
morning, at which *lm# the match
was adjourned because of lengthy
consultations by the 'Oxford team.
During the entire period excellent
contact was maintained between two
stations of the Haverford College Ra-„
dio club and the English gmateur sta
tion.
All communication was on a wave
length of 85 meters. Few Interrupt
