Description

Verfahren zur Ausscheidung des ersten Spannungsstoßes von Doppelzeichen oder von mehreren aufgenommenen Impulsen eines Zeichens Im Hauptpatent wird vorgeschlagen, zur Ausscheidung des ersten Spannungsstoßes bei Doppelzeichen o. dgl. durch den ersten Spannungsstoß einen Kondensator zu entladen, der sich dann langsam bis zum Eintreffen des nächsten Stoßes wieder auflädt und während seiner Aufladezeit die Empfangsanordnwig sperrt. Bei der Durchführung dieses Verfahrens war daran gedacht, den ersten Spannungsstoß vollständig zur Entladung des Kondensators heranzuziehen. Es hat sich jedoch gezeigt, daß es in bestimmten Fällen zweckmäßig ist, nur den ersten Teil eines Zeichens zur Entladung des Kondensators zu verwenden.Procedure for eliminating the first surge of double characters or from several recorded impulses of a character The main patent suggests for the elimination of the first voltage surge in the case of double characters or the like first voltage surge to discharge a capacitor, which then slowly up to the When the next surge arrives and the Receive order blocked. In carrying out this procedure, it was thought that to use the first voltage surge completely to discharge the capacitor. However, it has been shown that in certain cases it is appropriate to only use the to use the first part of a character to discharge the capacitor.

Erfindungsgemäß werdenTelegraphiezeicheit ausgesandt, und der Ladekondensator der Empfangseinrichtung wird derart bemessen, daß seine Ladung bereits durch den ersten noch nicht durch den Nachteffekt oder ähnliche Störungen verformten Teil eines au der Empfangsstelle eintreffenden Zeichens gänzlich verbraucht wird.According to the invention, telegraphy signals are sent out and the charging capacitor the receiving device is dimensioned so that its charge is already through the first part not yet deformed by the night effect or similar disturbances of a character arriving at the receiving point is completely used up.

Die hierbei vorkommenden Verhältnisse sind in der Abbildung näher veranschaulicht. Es ist hier das an der Empfangsstelle ankommende Zeichen gezeigt. Das durch die Bodenwelle übermittelte Zeichen B (Telegraphiestrichzeichen) hat die übliche rechteckige Form. Der Bodenwelle ist jedoch die Raumwelle überlagert, so daß durch den Raumwellenanteil R die rechteckige Zeichenform von einem bestimmten Zeitaugenblick T ab in eine regelmäßige übergeführt wird. Es wird nun erfindungsgemäß vorgeschlagen, die Anordnung des Hauptpatents so einzurichten, z. B. durch entsprechende Dimensionierung des Entlade- bzw. Ladekreises für den Kondensator, daß die Kon.densatorentladung nur durch den Anfangsteil des durch den Nachteffekt nochnicht verformten Zeichens ausgelöst wird. Erfolgt die Entladung des Kondensators zwischen der Zeit A und T, so wird der Entladevorgang durch den ersten Teil des aufgenommenen Zeichens ausgelöst, d. h. durch den Teil des ankommenden Zeichens, das noch die rechteckige Grundform besitzt.The relationships that occur here are illustrated in more detail in the figure. The character arriving at the receiving point is shown here. The character B transmitted through the bump (telegraph line character) has the usual rectangular shape. However, the sky wave is superimposed on the ground wave, so that the rectangular character shape is converted into a regular one from a certain instant T from a certain time instant on by the sky wave component R. It is now proposed according to the invention to set up the arrangement of the main patent such. B. by appropriate dimensioning of the discharge or charging circuit for the capacitor that the Kon.densatorentladen is triggered only by the initial part of the character not yet deformed by the night effect. If the capacitor is discharged between time A and T, the discharge process is triggered by the first part of the recorded character, ie by the part of the incoming character that still has the basic rectangular shape.
