invention

Operation of electric clocks using electric waves

Franz Morawetz was a technical pioneer in the field of clocks. Together with Dr. Max Reithoffer invented and developed in 1905 a "device for operating electrical clocks using electrical waves". In the case of a signal sent by a central station at certain time intervals, the invention consisted in the fact that a drive was opened in the receiving station by this received signal, which then gradually returned to its original position, inhibited by a spring by a pendulum, and only then did the temporarily interrupted receiving circuit closed again to wait for the next pulse. Since the transmission time intervals were set to about 1 minute, the reception of every single minute transmission signal pulse would have been necessary for sufficient accuracy. The invention received a patent in Switzerland and at the Imperial Patent Office in Berlin .

Since the invention could not be implemented in practice, it was not marketed.
