INFRARED DE-ICING RADIATORS are proposed by J. D. Altemus, of
Roslyn, N. Y., as a new solution to one of aviation’s most insistent prob-
lems. Mounted on the nose and propeller hub, the radiators would focus
their beams on the propeller blades and leading edges of the wings to |
keep them above icing temperature.
TRACER BULLETS that ignite fast
enough for use in short-range tom-
my guns have been designed by Col.
Sterner St. P. Meek, U.S.A. By increasing the ex-
posed area of the igniter compound on which the
propellent powder acts, and shortening the fire's
path through the compound, the tracer material is
made to ignite almost instantly after the discharge.
A NEW DIRECTION FINDER employing a
cathode-ray oscilloscope has been developed
for planes by Donald G. Little, of Baltimore.
As the loop antenna revolves, a circular wave
pattern appears on the oscilloscope screen,
which is calibrated to 360 degrees. When radio
signals begin to come in, a depression appears
in the pattern to indicate the direction from
which they are being sent.
FLAME-THROWING TANKS that are said to be able to spew out their jets of fire a dis-
tance of 110 yards are reported to be among Germany's new ‘secret weapons.” The tanks |
are also said to be equipped with a smoke-screening device that makes it possible for them
to envelop themselves in a thick artificial fog in a matter of a few seconds. |
MINE-LAYING U-BOATS are now believed to be in use by the Germans in an effort to de-
stroy the bridge of ships carrying supplies to our allies and overseas forces. In addition to
torpedoes, the U-boats carry a substantial load of mines which they can plant while sub-
merged by dropping them from slotted chambers.
