    Telegraphenanlage.   



   Gegenstand der Erfindung bezieht sich auf eine Telegraphenanlage nach Patent Nr. 71457, deren Wesen darin besteht, dass Wechselstromsendeapparate auf bestimmte Periodenzahlen eingestellt werden können, um mit je einem der durch gemeinsame Leitung verbundenen, auf die gleiche Periodenzahl abgestimmten Empfangsapparate wahlweise in Verkehr treten zu können. Gemäss der Erfindung werden Sendeapparate verwendet, die statt Wechselstrom Wellenstrom oder intermittierenden Gleichstrom liefern. Zur Verwendung derartiger Sendeapparate ist eine Umgestaltung der Apparatur erforderlich, welche jedoch hauptsächlich nur die Sender betrifft. So kann z.

   B. für intermittierenden Gleichstrom ein mechanischer Unterbrecher vorgesehen sein, welcher entweder mit ver- änderlicher Tourenzahl oder mit veränderlicher Segmentzahl ausgerüstet ist, oder welcher sowohl rücksichtlich der   Tourenzahl   als auch der Segmentzahl veränderlich eingerichtet ist. Als Stromerzeuger kann ein beliebiger Gleichstromgenerator dienen, ebenso wie auch für die Erzeugung des Wellenstromes beliebige bekannte Apparate Verwendung finden können. Für die Telegraphenanlage ist es sodann nur erforderlich, dass einer jeden Station als Telegraphenstrom ein Wellenstrom bestimmter Pulszahl bzw. Wellenzahl oder ein intermittierender Gleichstrom bestimmter Unterbrechungszahl zugewiesen wird. Im übrigen entspricht die Anlage der Einrichtung gemäss dem Stammpatente.

    Telegraph system.



   The subject of the invention relates to a telegraph system according to patent no. 71457, the essence of which is that alternating current transmitting devices can be set to certain number of periods in order to be able to enter into traffic with one of the receiving devices connected by a common line and tuned to the same number of periods . According to the invention, transmitting apparatuses are used which supply wave current or intermittent direct current instead of alternating current. A redesign of the apparatus is required to use such transmitting apparatus, but this mainly only affects the transmitters. So z.

   B. for intermittent direct current a mechanical breaker can be provided, which is equipped either with a variable number of revolutions or with a variable number of segments, or which is set up to be variable in terms of both the number of revolutions and the number of segments. Any direct current generator can serve as the power generator, just as any known apparatus can be used to generate the wave current. For the telegraph system it is then only necessary that a wave current of a certain number of pulses or wave number or an intermittent direct current of a certain number of interruptions is assigned to each station as a telegraph current. Otherwise the system corresponds to the facility according to the parent patent.
