Description

Einrichtung zur Beseitigung. von Störungen bei drahtlosem Zeichenempfang durch die Zündmaschine, insbesondere bei Flugzeugen. In dem Patent 377319 ist eine Einrichtung zur Beseitigung der Störungen geschützt, die bei Flugzeugen und auch sonst in der Nähe von Explosionsmotoren durch die Ausstrahlung von kurzen elektromagnetischen Wellen hervorgerufen werden, die von der Zündung des Motors herrühren. Der Grundgedanke der dort geschützten Erfindung besteht darin, daß die Zuführungen zu den Zündkerzen des Motors aus einem Leiter von hohem Widerstand, nämlich einer Kette, gemacht werden. Die Eigenschwingungen des bei der Zündung erregten schwingungsfähigen Systems, dessen Hauptteil die Zuleitung zur Zündkerze bildet, «-erden dann infolge der starken Dämpfung fast völlig unterdrückt.Facility for disposal. of interference with wireless character reception by the blasting machine, especially in aircraft. In the 377319 patent there is one Facility to eliminate the interference that occurs in aircraft and also protected otherwise in the vicinity of explosion engines due to the emission of short electromagnetic waves Waves caused by the ignition of the engine. The basic idea the invention protected there is that the leads to the spark plugs of the motor can be made of a high resistance conductor, namely a chain. The natural vibrations of the vibratory system excited during ignition, its The main part forms the lead to the spark plug, then earth due to the strong damping almost completely suppressed.

Praktische Versuche haben nun ergeben, daß nicht nur eine Kette zur Unterdrückung der kurzen Wellen Verwendung finden kann. Die gleiche Wirkung wird auch erzielt, wenn die Zuleitung so ausgebildet ist, daß sie an einigen Stellen einen hohen Ohmschen Widerstand besitzt, an anderen aber gut leitend ist. Die Zuleitungen können dabei statt aus einer Kette auch aus homogenem Stoff oder auch aus verschiedenen Stoffen bestehen.Practical experiments have now shown that not only a chain for Suppression of the short waves can be used. The same effect will also achieved if the lead is designed so that it is in some places has a high ohmic resistance, but conducts well at others. The supply lines Instead of a chain, they can also be made of homogeneous material or of different materials Substances exist.
