Transfer to Commerce
Department.
New York, March 27.—The execu
tive order of President Coolidge trans
ferring the United States patent office
from the Department of the Interior
to the Department of Commerce,
thpreby placing It under control of
Secretary Herbert Hoover, was de
fined by Dr. I,ee De Forest, "father of
radio," as "the most forward step In
Ihe history of the patent office since
its creation in 1790.
The importance of the patent sys
trin, Dr. De Forest pointed out, is
based on the first article of tlie con
stitution of the United States and
takes precedence over tlie clauses In
til© constitution giving congress the
right to declare war, to raise^ind gup
M port an army and naVy, or to con
stitute inferior federal courts below
that of, the United States supreme
court.
"That indicates how important the
framers of the constitution considered
the progress and protection of science
and useful arts to authors ami In
ventors. Now, if this congress will
take recognition that It is pitifully
undermanned and pitifully underpaid,
it will have rendered a service to the
advancement of science and art in
this country the value of which is
inestimable," Dr. De Forest said.
Slow Progress.
"This blindness of congress is re
sponsible for long delays and other
obstacles to modern progress created
because it does not seem to under
stand the tremendous volume of work
the bureau is required to do. Though
issuing over 50,000 patents and trade
marks each year, it requires 12 months
or more to get an application through.
This could be accomplished with in
creased pay and personnel, and the
member who introduces a bill that
finally passes to bring this about will
do much toward the etching of his
name in ihe hall of fame and have
the support of all forward-looking
business men in the United States."
Capt. Samuel E. Darby of patent
counsel for the De Forest Radio com
pany, and Dr. De Forest, former chief
clerk of the United States patent of
fice ami member of the examining
corps, stated that, while the patent
division was In effect an independent
bureau, the change to the Department
of Commerce was a step for greater
-efficiency, as its relations with Sec
* retary Hoover's department was more
intimate than with the Department
of the Interior.

A. M. 1. R. K.
When one employs regeneration 1
usually means a two-control set
even when no radio-frequency h
used ahead of the detector. However
It actually Is possible to have r
single control regenerative set, In
eluding a stage of radio-freqiier.cj
amplification. Such a receiver it
shown In Fig. 1. Both plati
colls, L2 and 1.5, are variable, in thai
their position may he adjusted unti
best results are obtained, but onc<
that position is determined there it
no further need of varying them
They remain fixed for all time.
The two semi-adjustable tickler?
are interrelated in their action, tht
actual effect of the RF tickler being
that of a sort of vernier adjusiment
of the detector stage tickler. It is
true indeed that regeneration Is
doubled up, an unsiftlsfactory and
unstable combination where both
constantly require control. But in
this circuit the tickler. 1,5, is su
placed that It gives best regenerative
effect on tlie lowest wavelength sta
tion to be received. Thereby the set
will not spill over on any of the
higher wavelength stations.
Sodion Is Advised.
Tlie success of the circuit is made
possible largely by using the new
Sodion tube as a detector. This tube,
unlike any other, permits the audi
bility of signals in a regenerative cir
cuit over the entire dial setting
range below that of resonance. When
other tubes are used the signal us
ually disappears as soon as the
tickler Is detuned slightly. More
over, the combination of circuit and
tube makes for sufh sensitivity that
I have been Able to tune in the local
stations on the speaker without us
ing either aerial or ground.
The set produces signals of excel
lent quality, functions over the en
tire broadcast band without notice
able radiation, produces gieat volume
and is capable of considerable dis
tance reception, although not as
great I>X as the regulation tuned
Itequireinenis men.
"As Dr. Pe Forest has said, the
fact remains that the personnel of the
patent office is woefully underpaid.
The requirements for appointment to,
the examining corps are quite severe
and practically none but graduates
from technical schools can find a
place upon the staff. It requires a
year for him to reach a state of use
fulness. and by the time he has ac
quired the necessary proficiency and
efficiency the government loses him
to some Industry or patent law office
that recognizes his ability and is will
ing to pay him double or triple his
government stipend.
“While the delays in the patent of
flee are not due wholly to this cause,
they are due In a measure to enor
mous increase in patent applications
that Industrial development has
brought, about, increasing the burden
of the bureau without adequately in
creasing the staff to handle it.
"Kllmination by Secretary Hoover
of the burdens imposed upon Ameri
can patentees in other countries that
are not imposed on their citizens in
this country will mean much to in
ventors and manufacturers of the
I'nited States, and every support
should be given by industry and com
merce to bring this about."
Test “B*’ Batteries.
» When you test the "B" batteries
^nd find that one Is dead, discard it
by all means. Jf you do not take it
out of tlie circuit, It will shorten the
life of the other batteries. Many fans
purchase one battery at a time and
place it in the circuit with tlie older
ones. This is also poor Judgment,
unless you wish to purchase batteries
frequently.
TRAINING COURSE
FOR ANNOUNCERS
Preliminary to the announcement
of a course of training for the an
nouncera at Stations W.IZ and WJY
of the Radio Corporation of America,
tests will he made to, determine the
essential qualifications of the ap
proximately perfect radio announcer.
A committee consisting of research
engineers, college professors, music
and dramatic critic*, prominent busi
ness men nnfl raldo editors has been
formed to pass upon this important
question. Phonograph records have
! pen made of the speeches of radio
tnnouncers at every important broad
-astlng station east of the Missis
dppi. These records will be run off
for the benefit of the committee, who
will Judge which Is the best. The
committee Is expected to meet at an
early date.

Radio to Enable Father to Hear Son

Out In 1h» little town of Pocatello,
Idaho, a man, bowed with advancing

The aon Is Victor I^irsen, now a
New York advertising man, and a
talented concert and oratorio baritone
singer. The father Is Kmll Larsen,
a furniture denier of Pocatello, Idaho.
Thirty years ago, when the son was

'he boy's mother, died. The father,
then a newcomer from Norway, left

R. F. and Regeneration With One Control; Quality Not Sacrificed by Parts Economies

Tuned radio frequency phis regeneration and resistance coupled amplification all on a single control. The two feedback rolls are adjusted to the operating point and felt without any
further adjustment.
radio-frequency amplification of the
transformer type.
The great purity of the signal qual
ity led to the desire to preserve it
In all its beauty, hence resistance
coupled audio frequency amplification
was usefl by the designer. However,
the circuit Is entirely satisfactory If
the usual two stages of transformer
coupled AF are used. That would re
duce the number of tubes to four,
somewhat lessening the quality, but
not reducing the volume.
The R. F. Inductance, 1,1-1,2, Is
most easily wound on two spider-web
forms of any convenient size, say,
feinch outside diameter with about
a 114-inch huh. The size Is not im
portant, except that it he large
enough to accommodate ^he winding,
which In each instance consists of
20 turns of Xo. 24 single silk-covered
wire. Thus, two separate coils are
wound. The hub is cut away from
each and the spokes pulled out, the
wire being lied with linen thread laced
at right angles to the winding tip and
down the points where the wires
cross. This performance is easily vis
ualized when the coll Is hplng made.
When the time comes to mount
these spider-web colls It Is convenient
to insert two dowels In each coll, a!
adjacent turns, and glue these dow
els into the Itusehoard, where holes
have been drilled at a slight angle for
this purpose. Before the holes for
the second coll support are drilled,
of course, the best inductive position
of the colls should he determined. This
usually will lie one of tight coupling.
Indeed, It might be rnfe to wind the
RF Inductance on a single spider-web.
consisting of 52 turns, cutting it at
the center for the two colls.
The plate of the RF tube is con
nected to one end of one of these
coils (1,2 ill Fig. II and the other end
of that coil goes to the primary of a
three-circuit variocoupler. The end
of the variocoupler primary goes to
"B" plus amplifier voltage. In this
case at least !)0. The variocoupler,
1.5 1.4 1,5. may he any standard one.
The only control Is the variable
condenser, tuning 1.4. the secondary
| of that coll. This condenser has a
| maximum capacity of .0005 nifil., nor
mally 23 plates, and should he of
good construction, along genuine low
loss lines. For best results on dls
tance a vernier dial Is necessary, but
for local reception the vernier will not
be necessary.
Those desiring to make their own
vario-coupler may wind 10 turns of
No. 20 double silk covered wire on
a 31 a Inch diameter tubing, 4 inches
high, and begin the secondary as close
as possible to the primary In the
Interest of greater stability. Tf great
er selectivity Is found vital this
coupling may be made looser by re
winding the primary >i-lnch or more
from the secondary. Therefore, start
the primary at least 1 lneh from one
end of the form. The secondary con
sists of 43 turns of the same kind of
wire, wound In the same direction.
The tickler is wound on a 1%-Inch
diameter and consists fit 24 turns of
No. 24 single silk covered wire. If a
4 Inch diameter tubing Is handy, use
a primary of seven turns, secondary
32 turns and a tickler of 20 turns on
a 3-inoh diameter tubing. In either
case the tickler may be spider web or
basketweuve. The number of turns
would lie the same as If the coil were
wound on tubing.
Basket weave Most Ffflclent.
The T»rens or basketweave type
of coil may be used to good ndvnn
ta.ge. For home construction It Is pref
erable to use large wire, such as No.
18 or even No. 18 double cotton cov
ered. The secondary Is begun first,
after 15 dowels have been erected on
a 3-Inch diameter at right angles
to the base of a 4 inch square board.
These dowels are Inch apart.
Measure on a straight lln* from
point to point. This renders easy di
vision of the circumference into 15
equal parts, each chord automatical
ly 24 degrees.
Wind 30 turns of wire, under two
and over two—that I*, over alternate
dowels—then pick up about 10 feet
of the sathe kind of wire and wind
the primary for 10 turns, simultane
ously and side by side with the sec
ondary. After the 10-turn primary is
completed the secondary winding is
continued for 13 more turns, making
a secondary with a total of 33 turns—
1. e.. 30, 10 and 13. Likewise the RK
coll might he of the Lorenz type, esch
comprising 28 turns of the No. 18 wire.
If the dowel sticks are five inches
long for this coil, then both LI and
L2 may be wound on the same form
and their Inductive relationship shift
ed right on that form by sliding the
top coll up or down. The easiest way
is to start with tight coupling, due
to the unlikelihood of being required
to change that.
The single dial may be placed In the
center of a 7xJ4-inch panel and under
a Dalco dial pointer. The pointer Is
not only useful, but Improves the ap
pearance of the set.
The single closed circuit jack J1
may be a double circuit Jack, with one
Inside c ontact to be ignored. The plate
is connected to the outside spring or
hooked arm of the jack, the "B" plus
90 volts to the other outside arm. this
one the right angle. The leaf or
spring cm the inside making contact
in ttie hooked arm that went to the
plate is connected to one side of the
.006 mfd. fixed condenser that lies be
tween It 1 and R2. This Jack may Ire
plugged in for earphone service.
Where Resistance* Go.
As for the resistances, R7 is a 10
to l' ohrn rheostat controlling the It.
K tube, which should Ire of the VY
201.V or 0-301A type. R2 is 2rt ohms
and controls the Sod0m Ir 21 detector
tube. This tube consumes .23 nm
per'e, like the 201A and 30IA. and dr
tects as well as the soft tubes that
draw one whole ampere each. The
resistance A Is an amperlte. type
D-12, which eliminates one minor con
trol. It is connected, one side to "A"
battery minus, the other side to the
filament minus posts of ail three audio
tube sockets. There is no detector
grid leak, ns the Sodlon tube nor
■ daily does not require one. R1 is one
megohm fl.noo non ohms!, as are T!3
and R3. R4 Is live megohm (300.000
rlimsl, R6 .23 megohnt (230.000 ohms!.
Switch SI is used to' turn tile set
on and off when, as is most usual, the
machine Is set for speaker operation.
The rheostats need not be adjusted
every time the receiver is used, al
though perhaps distance reception
may be cleared up a little by testing
these filament resistance* for best re
suits. This, however. Is not one of
those alleged on# knob regenerative
sets that really have two controls,
the rheostat critically governing re
generation.
Switch S2 enable# you to put out
the last two audio tubes when you’re
listening on earphones.
Cl is the variable tuning condenser.
C2 a .00025 mfd. fixed grid con
denser, C3 a .001 or 002 mfd. fixed
by pass condenser. The optional grid
leak would be connected from the G
post of the detector tube to the fila
ment plus post of that tube, and. If
used, should he variable, such as the
Bradleyleak, Kil Ko Leak, Turnlt and
the like.
it’s indeed odd that a tube that
functions without any leak will, when
it docs require a leak. demand a
variable one. for the leakage Is then
critical. The tube, however, is not
like the ordinary ones. Tt has a novel
filament, with an extra heating wire
and evidently a good Internal leakage
path. The filament heating control*
the leakage to some extent.
The Audio Amplifier.
For 1 hove desiring to build their own
audio amplifier, even grid leaks around
the house may be tried for HI, 2. 3. 4.
5. 6. They should be of approximately
the values stated, or variable leaks
may lie used. The standard resistances
for this circuit are purchasealile In a
radio store. E\en the audio resistance
part of the circuit may lie purchased
complete (Parent. In that case It
would he e isler to put the jack .11 In
the detector output lnstoad of the first
audio output.
Ths circuit, one# built, will prove a
surprise to many. I tried it for 10
successive nights, and each night
brought greater delight than Its pred
eiesscr. I used my Western Electric
i nne speaker, and there are few sets.

RADIO DEVELOPS
NEW VOICE TYPE
Radio has developed an entirely
new type of .vocal artists whose
voices surpass In sweetness those of
some of the more famous concert
stars, according to Franklin C. K.
Rundqulst, mu seal director of sta
tion WHT. which is preparing to
open In Chicago.
L undquist explained that these
voices, because of their lack of vol
ume, could not have been given to
the public without the radio. For the
most part, he said, they would not fill
p\en a small hall, but have a quality
of delicate sweetness impossible to be
found in a voice of greater carrying
power.
"Before radio broadcasting swept
the country, these voices were what
is known as ‘parlor voices." confined
largely to home and a small circle
of friends. The system of sound
amplification in radio has supplied
the power and volume necessary to
make them h*»ard in every corner of
the world, and the radio voices.’ as
we now call them, are heard nightly
ir. thousands of homes.'*

loopholes in the wave hand for Ca
nadian broadcasters The most an
noying of the recent interference
cases reported was the heterodyning
of PXRO, Ottawa, with WJZ. New
York.

his church clearly. *1 even, heard
