NEW YORK, January 23.-Perfected
methods Of fac-simile reproduction by
wire and wireless are foreshadowing
new era in communication, in the opin-
ion Of interested engineers.
Improved apparatus developed by
Charles j. Young, son of Owen D.
Young, permits the reproduction Of
handwriting, weather maps, and even
printed pages Of newspapers at speeds
lmpractlcable with systems now In use
Youngs apparatus, adaptable either
TO Geographic or radio use, produces at
the receiving end an almost exact re-
production Of material fed into the
transmitter. In its present stage it op-
crates more satisfactorily with written
and printed matter than with photo
graphs.
The new apparatus has already met
such tests as sending a weather map
by radio to ships far at sea and trans
mitting the whole front page of a news
paper from San Francisco to Schenec-
tady. N. Y, within few hours after
the paper went to press
transmission time now is on the
basis OF an inch a minute, requiring
little more than IL minutes to send a
typewriter page. Of standard letter
Size. 81a by 1l12 inches. The words
per-m1nute speed is governed largely
by the number Of words that can be
put within that space.
| The new facsimile method, some
what similar to the basic telephoto
method, but capable of being speeded
up throughout the entire process. was
flrst developed by Young at Schenec-
tady and later transferred to the r. C. A.
laboratories at Camden, NJ j., where
equipment used in the tests with ships
at sea was designed and constructed.
The recorder in the earlier fac
simile models depended upon an elec7
trically controlled pen to make a copy
OF the material at the transmitter This
method, while slow, records either in
the form OF dots or wavy lines. the
grouped whole completing the picture
or the message.
The improved recorder works on the
same basic system, except that the pen
Is eliminated and replaced by a bar Of
metal whose simple action Is one Of the
main reasons for the increase in speed.
Rolls OF carbon paper and white paper
are placed in the machine, the printer
bar pressing the carbon against the
paper and making an impression
thereon in response to the impulses
being received
Another secret Of the increase in
speed Is specially designed metal
drum over which the carbon and the
paper ride, the drum and the printer
bar working together to comprise the
printing mechanism.
The transmitter, like that for tele-
photo depends upon a photo-electric
cell to turn the material to be sent
into electric impulses. The letter or
picture to be sent automatically fed to
a drum which revolves under q con-
centrated beam of light.
This light is reflected to the photo
cell and from there sent either by wire
or wireless. at the option of the expert
menter- Special amplifiers are used.
the quality Of the received copy being
dependent to certain extent upon the
volume Of the incoming signal.
Simplicity has been one Of Young's
principal goals, and he has brought his
apparatus to point where neither
transmitter nor recorder requires much
attention.
