The Prevention and EIiminn ton 4
RRdl0 Trnuhles- ILL.

In many cases detector circuit
will work all right, but the amplifier
introduces so much distortion, pro-
ducing Earbled speech and noisy
music, that the effect is all but pleas
ant.
In such cases the trouble can often
be traced to the lack of a battery
for putting the proper grid potential
on the grids of the amplifying tubes.
{ battery can be inserted into
circuit very easily by disconnecting
the r or A terminals of the second
airy winding of the transformers from
the points where they connect to the
hlament circuit and connecting them
instead with the negative terminal OF
a ur-and-one- -half-volt c battery.
The positive terminal of the G battery
should be connected with the mega
tive A battery lead.
If you insist on doing away with the
battery. be sure that the grid re-
turn leads from the secondary wind
ings of the transformers are con-
nected with the negative A battery
lead and not with the positive A bat
terry lead
When radio frequency amplification
of the ordinary untuned or tuned type
is used in receiver for reception on
local or comparatively local stations.
the use of potentiometer is not nee
essary If fairly good aerial is used
with the set. If, however, you use
poor aerial or want to receive dis
tant stations, the use of A potenti-
omcter is necessary for good results.
In such vases a potentiometer. pref
erably 400-ohm one. is connected
across the \ battery leads and the
grid return leads from the secondary
winding of all the radio frequency
transformers, except the one just be
fore the detector, should be connected
with the movable or slider arm OF
the pOtentiometer. A .00l to .O02 mid.
condenser connected between the slid =
cr arm of the potentiometer and the
negative a battery lead is advisable.
but not absolutely essential
When no pOtentiometerS or G bat
teries are used, a good rule to remem-
bcr is to connect the grid return lead
from audin and radio frequency
transformers with the negative A
battery lead. The only exception as
mentioned above is the grid return
lead of the detector circuit which
should be connected with the positive
y battery lead.
This is especially true in reflex

their respective programs. The con-

series of ten and will be broadcast
direct from Carnegie Hall, New

The Philharmonic Orchestra will
play under the direction of William

few changes in the makeup of the
orchestra. II. Lang is the new con

is Il new third oboe, a new clarinet,
a new second trombone. a new second

nected with the negative A battery
lead
When high amplification is desired
and two or three stages of audio am
plification are used to attain the de-
sired volume, distortion is very apt
to be present to considerable de-
gree. In many such cases the trouble
can be remeded by connecting fixed
condensers of from ,00025 to .002 mfd.
across the secondary windings of the
second and third stage amplifying
transformers, the best values depend
ing on the constants of the trans
formers used.

especially of the tuned type the cir

Justment is made to bring in the sta

brought back to its original condition
by bringing the adjusting dial or

In such cases touching the finger to

the adjustment has been returned to

cillation and bring back the signal

to pass the point where the circuit
went into oscillation. To facilitate Q

grid Of the tube. BY touching the
screws the effect is obtained without
opening the cabinet.
In many cases the circuit can be

sigma Of ONCE and say to his new
friends, Gentlemen, come with me-"
, This work of the police Is to be
commended. Swindling some kinds Of
men seems to be so easy that 1t lacks
craftsmanship. and Washington does
veil to put a quietus on the penny
matchers. These fellows were once
called ICON men," "con" being the ia
miliar term for confidence" Sometimes
they were called "fim-ham artists" !"
though they were often more crude
than artistic. Before it became nec-
essary to protect innocent and child
like men from penny matching there
was game called three-card monte.
Years ago engaging strangers whose
principles were not the highest would
induce strangers to play this game
in the Smithsonian grounds. That
was when the Pennsylvania Station
was at Sixth and B streets. We used
to hear a good deal from victims who
played the game in the Monument
Lot before it became an imposing and
frequented park, and in the days when
old Jackson City, at the Virginia end
of Long Bridge. was prominent in
crime many robberies and swindles
were committed there.
1t seems strange to those who have
some grains of common sense and
who read newspapers that there are SO
many people who will let a stranger
come up to them. tell them what kind
Of weather it is, take them for walk
to see the town, entertain them with
game of pennies and take their roll.
But there is no use shutting ones
eyes to the fact that sharpers pick
out many foolish men, and for some
time Union Station seems to have been
hunting ground for these human
hawks.

"The," or CLOS" or Both :

Sticklers for the niceties Of language
aver that the new name OF ZR-3,
christened in this city on Tuesday, is
Los Angeles. They insist that the
addition of the article the before the
name is needless, grotesque, illogical
redundancy. inasmuch as Los Angeles
means 1.-The angels" They are un-
doubtedly correct. There is no mis-
taking the force Of their contention.
Los Angeles is a sufficient, self-con.
tanning title. It is a name. It Is com.
piete.
Nevertheless, in all likelihood, this
great dirigible will be known to and
by most people by its redundant name
with the article duplicated.
Nature will have to take its course
in this matter. If the public gets set
on using the English article ahead Of
the Spanish in referring to the airship
no citation Of grammar will possibly
check the custom. It Is one Of the
strong habits Of the American people
to use articles freely. 1t was in
recognition Of this fact that 4 good
many years ago, when Gov. Pinchot
was chief forester, he was saved from
a technical blunder by his associates
in that service who insisted upon the
naming of timber reservation near
that city 1.-THE Angeles National
Forest" Mr.. Pinchot wanted to put
in both the 1.-The" and the Los" so
the 1.-The" was saved, but the Los
was scrapped and propriety was pre-.
served.

The Langdon Grade Crossing.

The Langdon grade crossing comes
into the news again, but this time not
as the scene Of a tragedy. A number
Of persons have been killed at that
crossing, protests against its con-
tinuance have been numerous, and
there Is general recognition that this
grade crossing, one Of the last two or
three in the District Of Columbia,
should be eliminated. The Commis.
sioners favor the abolition of this
crossing, the railroad company is un-
derstood to be in favor Of the change,
and all that has preserved this cross.
ing has been the need of funds to
abolish it. The cost OF realigning or
regarding roadbed or highway in
order that railroad tracks and streets
shall not intersect at the same level
is borne jointly by the District and
the railroad company. In the last few
years that part Of the District in
which these grade crossings are To-
Gated has made a remarkable gain in
population and traffic volume. Con-
gress has made appropriations the
District so sparingly in that time that
funds have not been available for
grade-crossing elimination. But now
there is no warrant for further delay.
The two or three remaining railroad
grade crossings in the District, in.
cluding that at Langdon, should be
cured. with no further postponement.
