NEW FAST ACTION CAMERA.

Of the conditions will probably lead to
the production of stronger, sitter
blades.
The navy also had pictures made of
several pigeons being released from a
basket at the start of a race. The
point in question was whether the
pigeons bumped into one another and
were hindered at the start when re-
leased simultaneously from one bas-
ket. This picture showed the pigeons
did not interfere.
BY chance facts that pigeon experts
had never known were learned. The
pigeons wings were seen slowly rising
on the up stroke until they touched
over the back: then they dropped on
the down stroke and touched below the
breast. The pigeon flies so swiftly that
this popularity had never been ap-
parent to the eye.
The pigeon breeders were surprised
to find, too, that the feathers at the
TIP of the wing spread like fingers as
the wind goes through them on the up
stroke.
Since the tumbling pigeons taught
aviators how TO loop the loop. it may
be that the birdmen can learn further
secrets from the pigeon by the close
analysis of its flight that is now pos
sible.
This camera is for scientific pur-
poses. Just as a very high powered
microscope is necessary for some exact
ing laboratory work. so the ultra rapid
camera, with a prospect of attaining
100000 pictures a minute. will have
its place in scientific research.
Also Sends Radio Pictures
Mr.. jenkins has lately been attract
ing great interest by another invention
of his. an instrument for sending pic
lures successfully and now he is work
ing to send moving pictures by radio.
He knows how it is TO be done, but he
estimates that il will be about a year
before the necessary additional instru-
ments for the higher speed will be COM
pleted. The instruments for all of his
work have to be made AT great expense
and difficulty by manufacturers. The
necessary apparatus or parts are not
commercially available.
Sending moving pictures by radio is
merely an amplification Of the method
by which ordinary pictures can be sent.
the inventor says. The main principle
of the camera used in all Of his work is
a prismatic ring. a new optical shape
in glass.
BY means of these prismatic rings
and n photo-electric cell at the sending
station. the. light characteristics which
make I'D q picture are converted into
electric current characteristics Mr..
Jenkins explains. These in turn mod,
niatp radio waves employed as carriers
When these arrive at n receiving sta
ton the electric characteristics are
changed back into picture characteris-
tics bv means of another pair of pris-
matte rings and q light valve and the
scene at the sending station is repro
duced with fidelity.
IAN actual scene may be transmitted
as readily as a drawing or photograph.
At the several receiving stations it is
reproduced on a Photographic negative
with duplicate prints or on q moving
~picture screen for direct viewing.
The daily papers may get pictures
Of news events broadcasted from the
immediate scene without the delay of
anv Photographic process at the send
ing end. Paris and London events
coming west will be seen in America
some hours before they happen by the
clock.
"A criminal suspect may be stood
up in front of a broadcasting machine
and his image appear in every police
station in the country equipped with a
suitable receiving instrument. Detec-
tives could be called in to look at him
and identify him as his picture is shown
on a screen. or photographs can be
made by radio and filed away in police
stations for further use.
THE instrument would have tactical
value in event Of war. A battle on
sen or land could be watched as it oc-
CURED from the offices of the chiefs
in command at Washington"
But the greatest volume of business
when radio pictures are in use will
from the homes, Mr.. Jenkins on
cludes. BY sending music Of n wave
length and pictures or another. an en-
tire opera may be enjoyed through both
car and eye. Looking in. Al well az
listening in, is to be the next indoor
sport !
