Cheaper Motors Demanded.

The forced draft" employed on the
racing cars also may he adopted to
stock models. This is a development
really along the same lines as the
forced draft in steamers engine
room. 1t consists of a fan incloSed
in a housing which forces air into the
carburetOr to make the combuStible
mixture with the gasoline at a higher
pressure than that furnished by the
atmosphere. This results in more
rapid vaporiZation of fuel and addi-
tional power in the relatively small
piston displacement Of the modern
high-Speed motor.
More efficient and more economical
motors have been in demand for q
long time. This has given impetus to
experiments with air-Cooled motors,
and designs eliminating the overhead
and poppet valve types in favor of
single or double sleeve valves have
been evolved abroad by engineers of
the Rolls Royce Co. and others.

HOT WATER HELPS

Standards Experts Deter
mine by Series of Tests.

Hot jacket water in automobile en-
glnes helps reduce the thinning of the
lubricating oil. according TO tests
made by Bureau of Standards ex-
perts. In a cool cylinder, it is ex-
planned. the fuel is only partially
NaporiZed. and the unvaporized gaso-
line does not burn. Instead. It re-
mains In the cylinder and mixes with
the oil. and is carried into the lubri-
eating system of the engine. After a
while the oil becomes so diluted that
Its lubricating value is seriously i'm
paired, and 1t has to be replaced.
"Dilution may also be iessened by
high temperatures in the crank case
oil, as heat tends to separate the
gasoline from the OIL reads a state
ment issued by the bureau. The loss
of efficiency accompanying this dilu-
tion may be extremely small. for only
a very small portion Of the gasoline
fed to the engine is required to pro-
duce serious diiutions :.
Everything possible should be done
to reduce the time required to warm
up the engine in starting. as dilu-
tion has been found to take place
much more rapidly when starting
than after the engine has reached
its operating temperature. In start
ing, the gasoline consumption may be
as muCn as ~ times the normal rate,
and much of the unburned gasoline
gets into the oil. Dilution also. is
made worse by frequent starting of
the engine, with alternate short
period of use and of cooling off,
Tests made by the bureau have
shown that crank ease dilutiou is the
greatest drawback to decrease in
the volatility Of gasoline. For sew
eral years the bureau has been en-
gagged in a series of tests to determine
the effect of such a change on engine
performance, and has found that
when once warmed up an engine
using the less volatile : grade will
give as many miles TO the gallon as
one using the grade obtainable few
years ago.
The reason for such a change, 1t
is explained, Is that a greater pro-
portion of gasoline can be obtained
from given supply of crude oil if
the volatility is reduced.

Light Waves Speed Is
10000 Miles Second

The mysteries of the radio are never
ending. Scientists have now figured it
out that the speech of man in New
York, if broadcast by radio, is heard
in San Francisco before it is heard by
the audience facing him.
Astounding? Sure, but true just the
same, due TO the fact that the New
York audience hears by sound waves
which travel but 1,126 feet per second,
while radio audiences over the country
hear by means of vibrations or light
waves and these travel at the almost
incomprehensible speed of 10000
miles per second. AS San Francisco is
but 5000 miles from New York, it
would take but the veriest fraction Of
a second for the radio to transmit the
speakers voice to the Pacific coast,
less time than it takes sound waves To
carry the same voice to the audience
directly in front of the speaker.
The radio is the wonder of the age.

The latest Improvement in radio ap-
paratus. the low-loss doughnut coil
can be used in any of the neutrodyne
and tuned radio frequency to stabilize
the circuit. Its use in place of the
customary aperiodic coupler used for
tuning the first stage will improve any
existing receiver and is a good piece
of apparatus to incorporate in any re-
ceiver.
The interference, noise and general
tuning qualities of the first stage are
amplified and eventually become the
output Of the receiver If the first
stage is broad in tuning, the receiver
will very likely lack selectivity. The
action of the first stage has a great
deal to do with the ultimate perform
ance of the receiver.
Usual Type of Transformer.
The usual type of transformer used
has a single-layer wound coil on
tube, with tap taken off for the an
tenna connection. The field of the
magnetic lines of force around the
ends of the coil, created by the flow of
current through the wire, spreads out
and sprays nearby pieces of apparatus.
causing distortion and making the re-
ceiver unstable in operation.
The low-loss doughnut type of coil,
on the other hand, has an entirely self.
contained field that prevents magnetic
spraying effects The low loss feature
of the coil is due to the fact that the
wires are indented at every other face
around the coil. thereby lowering the
distributed capacity and resistance
losses below that of ordinary coils to
a noticeable degree.
To incorporate the coil in a regular
neutrodyne or tuned radio-frequency
receiver, all that is necessary is 70 re-

The life of any radio tube is gov
erned by the use it receives in the
hands of the operator. and its exist

filament burning out or decrease in
the electronic life of the tube. Now,
the burning out of tube may be
caused by excessive filament current.
or by a short circuit with the "B'
battery. or it may naturally burn out
of it's own accord. The decrease in
electronic emission in a tuhe is caused
by excessive filament voltage. or excess

of operators Of receiving sets can pro-
long the life or their tubes by burn
ing the filaments as low as possible
and by keeping the ''B" battery to 90
volts or less.
