ALSO Sends Radio Pictures
Mr.. Jenkins has lately been At
tracing great interest by another
invention Of his. an instrument for
sending pictures by radio. He has
already sent pictures successfully
and now he is working to send NOV
ing pictures by radio. He knows
how it is to be done. but he esti-
mates that it will be about a year
before the necessary additional in
/! struments for the higher speed will
be completed. The instruments for
! all Of bis work have to be made in
his own Laboratory, or else he has
to have them made at great ex-
| pense and difficulty by manufac-
turers. The necessary apparatus
or parts are not commercially
available.
Sending moving pictures by ra-
dio is merely an amplification Of
the method by which ordinary pic
lures can be sent, the inventor
says. The main principle Of the,
camera used in all Of his work is
a prismatic ring, . new optical
! shape in glass.
by means of these prismaic
| rings and a photo-electric cell at
! the sending station, the light char
acteristics which make up a pic
ture are converted into electric
current characteristics" Mr.. Jenk-
ms explains. These in turn mod
ulate radio waves employed as car
riers. When these arrive at . re-
ceiving station the electric char
acteristics are changed back into
picture characteristics by means OF
another pair of prismatic rings and
a light valve and the scene at the
sending station is reproduced with
fidelity.
! IAN actual scene may be trans
mitted as readily as drawing or
Photographic negative with dupli-
cate prints or on = moving picture
screen for direct viewing.
THE daily papers may get pic
lures Of news events broadcasted
from the immediate scene without
I; the delay Of any Photographic pro
cess at the sending end. Paris ant
London events coming west will b
seen in America some hours before
they happen by the clock.

called in to look at him and iden
tify him as his picture is shown OF
|! a screen, or photographs can b.
made by radio and filed away in pc
lice stations for future use.

But the greatest volume of bust.
ness when radio pictures are in
use will come from the homes, Mr.
jenkins concludes. By sendiO:

lures on another an entire ope.;
