REASONS FOR DOUBLING PART OF THE STORY
ABOUT IT
Reference made by The Tribune nearly
fortnight ago to apparatus devised by Herr
Szczepanik, an Austrian Pole. for teegra phicallv
reproducing pictures Detailed descriptions which
are published by London newspapers show that
the device is rather complicated one IN CON
struction, although simple In theory At each end
of the line are two mirrors which are made 10
oscillate rapidly one in direction and the other
In aDother. Both are covered with q substance
that makes the surface lusreess and on this coat
Ing are scratched numerous parallel lines which
expose the mirror. The bright bars OF one OF
these grdirons are vertical: those Of the other
horizontal. The scene picture to be trans
mitted is first broken up into a series Of points
produced by the intersections OF the rejecting lines
OF the mirrors. The oscillations Of the reAectors
are effected in such way that only one point OF
Eight Is projected at time; but they come in such
q rapid succession that to the human eye they are
practically Simultaneous
Al the other end OF tho telegraph wlre-only one
seems 10 be necessary-is another pair OF mirrors
made 10 oscate Simultaneously with the first ones.
"Synchronously" means precisely the same
time Consequently, the ser.es OF dots OF light
proceeding from stationary spot in the receiving
apparatus are caught and distributed by the mn D
