Description

Vorrichtung zur Beseitigung der störenden Wirkung der Zündvorrichtung für Motoren auf den Empfang drahtloser Meldungen, insbesondere auf Flugzeugen. Der Empfang drahtloser Meldungen wird auf Flugzeugen, von anderen Bedingungen abgesehen, durch zwei Faktoren hauptsächlich beeinflußt, und zwar s. durch die äußeren Geräusche, welche erzeugt werden durch den arbeitenden Motor, die Rotation der Schraube, die Vibration der Streben usw., z. durch die störende Wirkung des Systems, welches zur Zündung der Brennmischung im den Motoren dient und aus Hochspannungsmagneten oder anderen Apparaten, Zierzen und Leitern besteht.Device for eliminating the disruptive effect of the ignition device for engines to receive wireless messages, especially on airplanes. Of the Receipt of wireless messages is permitted on aircraft, except for other conditions mainly influenced by two factors, namely by external noises, which are generated by the working motor, the rotation of the screw, the Vibration of the struts, etc., e.g. due to the disruptive effect of the system which is used for Ignition of the fuel mixture in serves the motors and consists of high-voltage magnets or other apparatus, ornaments and ladders.

Zwecks Schutzes dieses drahtlosen Empfanges von dem äußeren GerJ1usch werden speziell Helme mit Ohrlappen, die fest an dem Kopf und an den Ohren anliegen, wie auch speziell so genannte Innentelephone benutzt, die in den äußersten Gehörgang eingeführt werden. Dadurch gelingt es, die Wirkung der Nebengeräusche des arbeitenden Motors von dem zu empfangenden Ton fernzuhalten. Immerhin ist die störende Wirkung der Nebengeräusche sehr groß. Deshalb müssen die aufzunehmenden Anrufe und Reden genügend intensiv sein, um dem Empfänger in dem Flugzeug zu ermöglichen, dieselben genau aufzunehmen; deshalb ist es notwendig, vollständige Verstärker anzubringen.To protect this wireless reception from external noise specially made helmets with ear flaps that fit tightly to the head and ears, as well as specially so called internal telephones which are used in the outermost ear canal to be introduced. This makes it possible to reduce the effect of the background noise of the working Motors away from the sound to be received. After all, that's the disturbing effect the background noise is very large. Therefore, calls and speeches need to be recorded be sufficiently intense to enable the receiver on the aircraft to do the same to record exactly; therefore it is necessary to install complete amplifiers.

Um die störende Wirkung des elektrischen Zündapparatsystems der Flugzeugapparate zu bekämpfen, sind ganz andere Mittel erforderlich, denn die störende Wirkung beruht auf magnetischer Induktion, aber hauptsächlich auf der Ausstrahlung der elektromagnetischen Wellen bei der Funkenbildung an der Kerze während des Zündens.To the disruptive effect of the electrical ignition system of the aircraft apparatus To combat it, completely different means are required, because the disruptive effect is based on magnetic induction, but mainly on the radiation of electromagnetic radiation Waves when sparking the candle during ignition.

Die vorliegende Erfindung beruht nun auf der L'berlegung, daß es nicht so sehr darauf ankommt, den Empfangsapparat abzuschirmen oder in der gleichen Weise zu schützen, sondern die Ausstrahlung der elektromagnetischen Energie des Zündsystems während der Funkenbildung bedeutend abzuschwächen.The present invention is based on the idea that it is not as much as it comes down to shielding the receiving apparatus or in the same way to protect, but the radiation of the electromagnetic energy of the ignition system to be weakened significantly during sparking.

Gemäß der Erfindung wird dies erreicht durch Anwendung von Leitern, die einen großen Ohmschen M iderstand gleichmäßig über die ganze Länge verteilt haben, durch welche der Zündapparat mit dem Motor verbunden ist. Derartige Leiter sind erfindungsgem;iß besonders wirkungsvoll herzustellen aus Ketten, welche z. B. aus Eisen bestehen mit einer sie überziehenden Oxvdschicht, aber ebenso auch aus dünnen Leitern aus Metallegierungen von großem Ohmschen @\-iderstand. Durch Anwendung vor. Leitern mit einem großen Ohmschen N\ iderstand kann man den Dämpfungsgrad der bei der Funkenbildung entstehenden Schwingungen bedeutend vergrößern und auf diese Weise die elektromagnetische Energie, die beseitigt werden soll gleichfalls abschwächen.According to the invention this is achieved by using ladders, the one large ohmic resistance evenly distributed over the entire length through which the ignition apparatus is connected to the engine. Such a ladder are according to the invention; iß particularly effective to produce from chains, which z. B. consist of iron with a covering oxide layer, but also made of thin conductors made of metal alloys with a large ohmic resistance. By Application before. Ladders with a large ohmic resistance can be used to determine the degree of attenuation significantly increase and increase the vibrations caused by spark formation in this way the electromagnetic energy which is to be eliminated likewise weaken.

Verbindungsleiter dieser Art zwischen Zündapparat und Motor kann man beispielsweise herstellen, wie schon ausgeführt, aus einer Kette aus oxydiertem Eisen oder in Form eines dünnen Leiters oder einer entsprechenden Legierung mit großem spezifischen Widerstand. Am besten zu diesem "/.weck eignet sich jedoch, wie schon oben ausgeführt, eine Kette aus oxydiertemEisen. weil hier die Kontaktflüche zwischen den einzelnen Gliedern nicht nur gering ist, sondern auch schlecht leitend ist, während sie für Funkenstrom einen guten Durchlaß bilden. Die Wirkung der Erfindung wird vergrößert, wenn die Außenarmatur der Kerzen und das Motorgehäuse mit: der Masse des Zündapparates durch gute Leiter in einigen Punkten verbunden sind, wie aus der Zeichnung ersichtlich ist. Eine derartige Verbindung hat eine noch bessere Wirkung gezeigt.This type of connection between the ignition apparatus and the engine can be used for example, as already stated, produce from a chain of oxidized Iron or in the form of a thin conductor or a corresponding alloy with large resistivity. The best way to do this, however, is as already stated above, a chain of oxidized iron. because here the contact curses between the individual members is not only small, but also poorly conductive while they provide a good passage for spark current. The effect of the invention is enlarged if the outer fitting of the plugs and the motor housing with: the Grounds of the ignition apparatus are connected by good conductors in some points, such as can be seen from the drawing. Such a connection has an even better one Effect shown.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, nach dem ein Sechszylindermotor dargestellt ist mit einem entsprechenden Zündapparat. Die punktiert dargestellten Leiter a sollen Ketten veranschaulichen aus Eisen mit oxydierter Oberfläche oder andere Leiter mit großem Widerstand. b ist die Verbindung der Außenarmatur der Kerzen mit dem Zündapparat und c der Leiter zur Verbindung einiger Punkte des hfotorgehüuses miteinander und mit der Masse des Zündapparates.An exemplary embodiment of the invention is illustrated in the drawing, after which a six-cylinder engine is shown with a corresponding ignition device. The dotted ladder a are to illustrate chains made of iron with oxidized surface or other conductors with high resistance. b is the connection the outside fitting of the candles with the igniter and c the conductor for the connection some points of the photo camera housing with each other and with the mass of the ignition device.
