Description
Im Vorliegenden ist eine besondere Ausbildung der Anordnung für Nachrichtenübermittlung mit und ohne Draht nach dem Hauptpatent 301234 beschrieben, und zwar besteht diese besondere Ausbildung der Anordnung darin, daß der Umschalter auch eine solche Schaltstellung aufweist, daß von den beiden Fernhörern der eine auf die eine Betriebsart und der andere Fernhörer auf die andere Betriebsart geschaltet werden kann. Es hat dies gegenüber der Anordnung in dem Hauptpatent den Vorzug, .daß die Stromkreise für die beiden Betriebsarten elektrisch völlig getrennt bleiben und trotzdem derselbe Erfolg herbeigeführt wird, . als wenn man die Telephone parallel auf beide Empfangsarten schalten würde, wobei es natürlich unvermeidlich ist, daß die Stromkreise der beiden Betriebsarten an der Stelle, wo die Fernhörer angeschlossen sind, elektrisch miteinander verbunden werden.·In the present case there is a special embodiment of the arrangement for the transmission of messages with and without wire according to the main patent 301234 described, and that there is this particular design of the arrangement is that the switch also has such a Has switching position that of the two telephones one on the one mode of operation and the other remote handset can be switched to the other operating mode. It has this over the arrangement in the main patent the advantage that the circuits for the two Operating modes remain completely separated electrically and still bring about the same success will, . than if you switch the telephones in parallel to both types of reception would, whereby it is of course inevitable that the circuits of the two modes of operation be electrically connected to each other at the point where the remote receivers are connected.
Nach vorliegendem Zusatzpatent bleiben die Stromkreise der beiden Betriebsarten elektrisch stets völlig getrennt, der Umschalter gestattet jedoch, genau wie in dem Hauptpatent, wahlweise beide Hörer nur auf die eine oder nur auf die andere Betriebsart umzuschalten, wobei auch weiter genau wie in dem Hauptpatent zugleich mit der Umschaltung auf die eine oder ändere Betriebsart eine Umschaltung (Parallel- oder Serienschaltung) der Telephone bewirkt werden kann.According to this additional patent, the circuits of the two operating modes remain electrical always completely separate, but the switch allows, just as in the main patent, optional to switch both earphones only to one or only to the other operating mode, whereby also continue exactly as in the main patent at the same time with the switch to one or another operating mode causes a switchover (parallel or series connection) of the telephones can be.
Auch die wechselseitigen Unterbrechungen ■ der Stromkreise zwangläufig mit dem Umschalten (z. B. die Unterbrechung der drahtlosen Senderanlage, wenn der Umschalter auf gleichzeitigen Empfang mit beiden Betriebsarten oder auf drahtlosen Empfang steht) erfolgten in der gleichen Weise wie bei dem Hauptpatent.The mutual interruptions ■ of the circuits also inevitably occur with the switchover (e.g. the interruption of the wireless transmitter system if the switch is for simultaneous reception with both operating modes or wireless reception) were done in the same way as in the main patent.
