Some European Inventions

In a recent report to the Department
OF State, Consul Guenther Of Frank
fort describes a new and ingenious
method Of welding pipes, discovered
by a German engineer 1t is known
as the Goldschmidt process. Briefly
stated, it consists in mixing alumi-
MUM with oxide Of iron and adding to
it an easily ignited substance. This
powder is put into a clay crucible and
then ignited by means OF a match.
The resulting chemical action renders
the mixture liquid, and this liquid Is
then poured around the place to be
welded The object assumes a white
heat. and the Welding is done by
very simple apparatus The welded
places show the same firmness as the
original piece. and manifold applica-
tion Of the method is possible. In the
near future it is proposed to weld the
rails Of the electric railway at Dres-
den, which has been done before in
other cities. The speaker welded the
rails before the audience. and the ex-
periments were pronounced success
ful, especially on account Of the sim
plicity OF the process. It Is consid-
cred a very important discovery. and
great hopes are entertained for it.
The Telephohograph.- ph.-Brainard H.
Warner, Jr., United States Consul at
Leipsig, thus describes the telephone
graph in a report published in the
September issue OF Consular Reports:
THE 'telephonograph,' a new invention
In which the German Postmaster
General, Won POdbielski, is much in
terested. is a combination Of tele-
phone and a phonograph for the pur-
pose Of recording messages received
during the absence of the operator.
This apparatus was invented by a
Dane BY the name Of Paulsen. The
person called up has only to hold the
trumpet to his ear upon returning to
the Office, even after an absence Of two
days, to receive the message. Many
inventors have tried to effect such a
combination, but all failed on account
Of the difficulty Of transferring the
message onto a wax cylinder Instead
OF a wax cylinder. Paulsen used a
flexible steel band in his phonograph,
which is much simpler in construction
than the Edison phonograph. Mes
sages are much more easily removed
from the steel band than from the
wax cylinder II is wound on two
spools. moving quickly from one to
the other. and coming into contact
with a very small electro magnet,
switched into the circuit, which Affects
the steel band in such a way as to
record on 1t any sounds that may pen
etrete TO the monographs. Il is only
necessary to cause the steel band to re-
pass the magnet in order to have the
sounds repeated. Each vibration Of the
electro-magnet produces a correspond
ing vibration Of the steel band. In
order to remove a message from the
steel band a magnet is passed over
the surface on which the message was
recorded. The tests recently made In
the engineering department Of the Co
penhagen Telephone Company. whose
service the inventor has recently en-
tered. were surprisingly successful. Up
to the present time the apparatus
records a song better than a spoken
message: but the latter IS. neverthe-
less, quite clear. and the experts who
have been making experiments in CO.
operation with the inventor. declare
that It is only a question Of time until
the telephonograph viii repeat a mes
sage as clearly as il can be heard
through the most improved tele-
phone.
