Description

Fernschreibmaschine Bei den heute üblichen Fernschreibmaschinen, ist das benutzte Alphabet den einzelnen Tasten so zugeordnet, daß sehr viele Zeichen sich nur um einen Impuls unterscheiden. Dies bringt insbesondere bei der übertragung mittels drahtloser Telegraphie den Nachteil mit sich, daß infolge atmosphürischer Störungen die Zeichen häufig verstümmelt bzw. statt eines beabsichtigten Zeichens ein anderes Zeichen gedruckt wirC. Besonders unangenehm ist die ungewollte Einschaltung der Taste für die Umschaltung von Buchstaben in Ziffern und umgekehrt.Teletypewriter With the teletyping machines commonly used today, is the alphabet used is assigned to the individual keys in such a way that a large number of characters differ only by an impulse. This is particularly beneficial when it comes to transmission by means of wireless telegraphy the disadvantage with it that as a result of atmospheric Disturbances often mutilate the characters or instead of an intended character another character is printed C. Unintentional switching on is particularly unpleasant the key for switching from letters to numbers and vice versa.

Dieser Nachteil wird, gemäß der Erfindun#g dadurch vermieden, daß den einzelnen Tasten, der Fernschreibmaschine Kombinationen eines Sechser-Alphabets derart zugeordnet sind, daß die einzelnen Impulskombinationen sich in mindestens zwei Impulsen unterscheiden, ähnlich wie bei manchen K-odes sich die einzelnen Kodewörter um mindestens zwei Buchstaben unterscheiden. Dadurch wird in den meisten Fällen erreicht, daß die. verstümmelt übertragenen Zeichen sofort erkannt werden, da nur in den seltensten Fällen mehr als ein Impuls verstümme#It wird. Hierbei ist es weiterhin zweckmäßig, den nicht belegten Kombinationen jeweils die Irrungtaste zuzuordnen.According to the invention, this disadvantage is avoided in that the individual keys, the teletypewriter combinations of a six-digit alphabet are assigned in such a way that the individual pulse combinations are at least two impulses differ, similar to how with some K-codes the individual code words differ differ by at least two letters. This will do in most cases achieved that the. garbled characters transmitted can be recognized immediately, as only in the rarest of cases more than one impulse is silenced # It. Here it is still It is advisable to assign the error key to the combinations that are not in use.
