  Hochfrequenztransformator. 
 EMI1.1 
   Telegraphie   angewendet werden. aus dünnen Blechen von etwa   0#03-0#1 mm Dicke hergestellt werden,   um die Verluste im Eisen möglichst zu reduzieren. Derartig hergestellte Bleche werden   zweckmässig   aus gestanzten ringförmigen Blechen angefertigt, so dass jeder Ring einen geschlossenen Eisenweg (ohne Luftspalt) für die Kraftlinien bildet. Die   Blechhöhe   dieser Kerne ist immerhin sehr beträchtlich, und 
 EMI1.2 
 dass die Transformatorenkerne aus sehr   dünnem,   emaillierten oder sonst passend isoliertem Eisendraht gewickelt werden.

   Da bei solchen gewickelten Eisendrahtkernen die einzelnen Windunge nicht in sieh geschlossen sind, jede   einzelne Windung also nicht einen geschlossenen Eisenring   bildet, wie dies bei jedem gestanzten Blechring eines aus Blechen zusammengesetzten Transformatorenkernes der Fall ist. werden die geschlossenen   Eisenwege   oder Ringe, in denen sieh   sehr ins (tewicht fallende schädliche Ströme   ausbilden, vermieden.

 isolierten Drähten gewickelt sind. Dieser Transformator ist auf der Sekundärseite durch die Abstimmungmittel 5 und 6 auf ein Vielfaches der Grundfrequenz abgestimmt. In diesem Kreise sind mit geeigneten Messinstrumenten sämtliche Oberschwingungen nachweisbar.

   Durch einfache Variation der statischen Abstimmungsmittel eventuell auch durch Anwendung von nicht dargestellten   Zwischen kreisen kann   jede beliebige   Oberschwingung herausgefiltert werden. Diese   kann durch eine   geeignete Kopptung so   auf die Antennen übertragen werden, dass darin Nebenschwingungen nicht mit auftreten. In der Zeichnung

   PATENT-ANSPRÜCHE :
1.   Hoehfrequenztransformator,   insbesondere für drahtlose Telegraphie. u. dgl. dadurch gekennzeichnet, dass der Transformatorkern aus sehr   dünnem,   isoliertem Eisendraht (maximal   0-1 w im   Durchmesser) gewickelt ist, um die Vielfachen der Grundfrequenz herauszufiltern.

  High frequency transformer.
 EMI1.1
   Telegraphy will be applied. made of thin sheets of about 0 # 03-0 # 1 mm thick in order to reduce the losses in the iron as much as possible. Sheets produced in this way are expediently made from punched ring-shaped sheets so that each ring forms a closed iron path (without an air gap) for the lines of force. The sheet height of these cores is nevertheless very considerable, and
 EMI1.2
 that the transformer cores are wound from very thin, enamelled or otherwise suitably insulated iron wire.

   Since in such wound iron wire cores the individual turns are not closed, each individual turn does not form a closed iron ring, as is the case with every stamped sheet metal ring of a transformer core composed of sheets. the closed iron paths or rings, in which very significant harmful currents develop, are avoided.
 EMI1.3

 insulated wires are wound. This transformer is tuned on the secondary side by the tuning means 5 and 6 to a multiple of the basic frequency. In this circle, all harmonics can be detected with suitable measuring instruments.

   Any harmonic can be filtered out by simply varying the static tuning means, possibly also by using intermediate circuits (not shown). This can be transmitted to the antennas through a suitable coupling so that secondary vibrations do not occur. In the drawing

   PATENT CLAIMS:
1. High frequency transformer, especially for wireless telegraphy. u. The like. characterized in that the transformer core is wound from very thin, insulated iron wire (maximum 0-1 w in diameter) in order to filter out multiples of the fundamental frequency.
