determinations showed that q grid
| leak of from five to six megohms was
about right with grid condenser OF
reliability. A variable Filko-Leak OF
six megohms rating covered all Of the
requirements 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 variable leak rang
ing from one to six megohms is used
on the grid of the tube. These two
lresistances are in parallel and con
sequently follow the law for parable
circuits. therefore we have actual re
sistance values of from .6s 2.3 meg
ohm to l. IL 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
elusive purpose Ito make It's com
mercia1 bow in the near future) is
shown in the photograph Fig. /
This receiver utilizes the IS" aug
mentation circuit with an additional
stage of audio frequency amplifica
ton. making in all three tube set.
This receiver has been designed ex
clusively for the business office-for
the business executive, il 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
are included in the top or cover OF
the set. The action OF raising this
cover turns the set on. Lowering II
turns the receiver off. The volumk
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 events
and hundred and one features OF
interest to the executive confined to
the office are thus made Immediately
available to him, and 1t 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 circuits of this re
ceiver. as well as CONGREGATIONAL de
tails on features of the augmenta
ton circuit will be explained in next
weeks article on this sensational
new circuit.

Navy Liberal
With Licenses
More Consideration to Be
Given to Experimenters
Than Radio Sellers.

Washington, Dec. 2s.-Practically
every applicant for license to manu-.
facture radio sets under the Won
Bronx Schloemilch reflex patent who
owns a patent under which a cross
license can be granted to the Navy
Department will receive one.
1t Is the plan of the navy to pur-
sue a very liberal course in granting
licenses under tho radio patents. 1t
is estimated that in the neighborhood
of lis applications have been received
hy the navy for licenses.
One of the factors to be taken into
consideration in granting licenses Is
the extent of experimental work be-
ing done 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
sets for profit.
There are two outstanding facts In
connection with the applications Tor
licenses under the navy radio pat
ents. One is that within very short
time q large number Of new reflex
sets may appear on the market. The
other is that there IL a tendency on
the part of automobile manufacturers
to enter the radio field. Several ap-
plications have been received from
this class stating desire to manu-
facture radio sets.
1t Is believed that a month or two
will be required before licenses are
granted.

RADIOS DIFFER
SEASON TO SEASON

A receiving set will not act pre-
cisely the same on any two days or
nights. SMessages are received better
after dark than in the daytime. be-
cause radio waves do not travel so
strongly by daylight as they do by
dark. In general, better reception
occurred during cooler months than
during the warmer ones. This Is be-
cause atmospheric conditions pecu-
liar to the seasons have a marked
effect upon radio waves. 1t 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.

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 are
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 one of the patent applica-
tions on signal augmentation as de-
veloped by Mr.. Hoyt. and will be ex'
planned in next weeks issue.
Commercial Adaptation.
The fundamental circuit shown In
last weeks 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 afforded the
equipment Of a detector and a radio
frequency amplifier although more
efficient than ths conventional stage
OF radio frequency amplification). The
circuit which is about to be shown
and described goes tho circuit OF last
week one better. in that the radio FIRE.
quency or augmentation tube is now
tho first stnge OF audio frequency as
we'll. This may be taken to be re.
flexIng-perhaps It is--but here again
there is something to analyze. and
above all else. certainly food for
thought.

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 Ito a greater or lesser degree)
with the grid leak removed. If the
grid condenser did not have direct
leakabe resistance it would be i'm
possible for the receiver to function,
as there would be no path for the
accumulated e1ectrons on the grid of
the tube to leak off to the filament
and the grid would be maintained at
a negative poential as a result. Now,
since commercial grid condensers do
posses a leak value, We must con-

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 1t
will be seen that complications set

Interchanging Tubes.

A set that is equipped with three
or more tubes will work better II
the tubes are changed from one
socket 10 another. The ampiification

generally said TO be the same for
all tubes of this type. but actually
the amplification factor. like other in
diyidual characteristics OF a tube,
varies slightly for each tube.

Down at Westport we find great
beds Of clans, great numbers of
merchantable crabs, and, in reality,
the very flower of the worlds best
fish, the four kinds of salmon. Grad
ually through the past 40 years, 3
great business grew up about the old,
old dock at Westport, until it amount
ed to 100000 . year.
This great business came mostly
out Of the ocean for miles north and
south of the Harbor, and might have
been 100000 3 year today, but for
the failure to keep that Westport
dock in repair.
By all manner Of means we must
restore that dock and bring back

lish this fishing business on such a
firm basis that it will never, never
cease. The fisheries of the seas viii

berry land is worth $4,000, then there
is a future cranberry development at
Glen Grayland that will mean $12,-

WORKERS ARE ENJOINED:
IGNORE USURPER'S ORDER

FILLER CITY, Mich, Aug. 2s.-
County officials have failed to induce
striking pulp, sulphite and paper
mill workers to cease picketing the
plant of the Filler Fiber company.
The injunction, issued by Circuit
Judge Vanderwerp, prohibits strik-
ers from assembling at cor in the
neighborhood Of" the company's
premises, or "at other places" with
intent to cause the employees to
leave the company's employ cor to
interfere with or obstruct in any
manner the business, trade and oper-
alton of the plant and MILL"
Under this order the strikers can
hold no meeting of their union, can
not picket, or even visit the homes of
strikebreakers.
The paper mill workers are ignor-
ing the order and refuse to cease
picketing, though county officials are
aiding the company by pleading with
the workers to "obey the law" The
workers reply: what law have we
violated?"
