TECHNICAL ASPECTS OF THE CINEMATOGRAPH
Dr. Mihaly has invented steel wire cinematography. It is highly probable that the eminent Hungarian scientist was inspired in his researches by the experiences of the German engineer, Dr. Stille, who has recently perfected a system for registering sound on steel wire by means of electromagnetic variations.
So far, we lack precise details on this new invention, which -may perhaps still be in the experimental phase, and, while awaiting that Dr. Mihali may endeavor to resolve the problem of television, we trust that the fullest success may soon crown his researches.
The scientific principle that guided Dr. Mihaly in his research has "been much talked of. It is not new; it was already applied several years ago, and now again claims our attention, thanks to Dr. Stille's studies, which have rendered it of practical industrial value.
We feel sure that our readers will be interested in a brief description of this invention.
At the Paris International Exhibition of 1900, the renowned Danish scientist, V. Poulsen, exhibited an apparatus invented by himself, which he called the Telegraphone, which at the time roused keen interest in all who had an opportunity to see it.
This was a simple mechanism which, by means of a steel wire, registered and reproduced sounds through the medium of electro-magnetic variations. This brilliant invention seemed to promise the greatest success, but it has, on the contrary, been overlooked for 30 years; so much so that, being brought before us again in its present form, as perfected by Dr. Stille under the name of the Mnemophone, it claims all the interest of a novelty.
Poulsen 's invention was based on the property of steel to receive a geater or lesser degree of magnetisation, and to preserve the same for a greater or lesser period of time, when placed close to a natural magnet or an electro-magnet.
Just as a variable electric current can create a proportional magnetic field, in like manner a variable magnetic field can create electric currents of identically the same variations.
Relying on this principle, Poulsen ran an electric wire between the nearly adjacent poles of an electromagnet inserted in the circuit of a pile and a microphone. The wire registered all the electro-magnetic variations produced by the vibrations of sound passing through the microphone.
