NEW YORK, Dec. Is. - European
rights Of the patents of Michael IdNor.
sky Pupin Of Columbia university gov.
erning his improvements in modern
long distanc. telephony have been sold
abroad by Professor Pupin for 4 sum
ag"regating more than SJUU,00O. His
invention makes telephony possible
over distance four times greater than
by the system generally in use at pres
emit So perfect is the transmission in
articulation that it has been found in
actual experiments by the German gov.
ernmcnt that conversation can be sat
iSfactorily maintained at distance of
thirty feet from the receiver, although
those telephoiling are hundred miles
apart.
Professor Pupin'S invention was first
brought into publicity in January, 1901,
when he sold the patents governing his
American rights to the American Bell
Telephone aud Telegraph company for
a sum said by Professor Pupln at the
time to be about S5OO,OOO His inven.
ton, willie not new has now its details
and cnDahility first authortarlvely de-
sCrihcd in the recent official report Of
the German government on the system,
which vcriiies not only all that was
claimed for the invention in this coun-
try, but even goes far beyond the
American estimates.
For his foreign patents Professor PHI
pin not only received S5oO,000, but will
also get substantial royalty. From
his invention. therefore. he Is put in
possession OF ut least 81 ,DOn,OUU. with
probabilities of large future income
from royalties.
In this country Professor Pupn's in
rcntion easily makes possible telephcn-
j" communication between New York
and San Francisco and has already |
been installed by the American Tclc- |
phone and Telegraph company be-
tween this city and Chicago, with
great improvements resultant
Abroad it offers no difficulty in the
way of establishing direct telephone
communication between Berlin and
London, Berlin and Copenhagen, Paris
and 81. Petersburg, Berlin and Stock
holm. etc. The problem Of Transatlantic
telephony has also become Il possibility
