Description
Kristalldetektor für elektrische Wellen. Die verschiedenen Kristalldetektoren für elektrische Wellen haben immer mehr oder weniger den Nachteil, daß sie teils durch Erschütterung und beim Transport, teils durch atmosphärische Einflüsse sehr leicht unempfindlich werden. Es ist dann mit viel Zeitverlust verbunden, die Detektoren wieder sorgfältig einzustellen und den Empfänger wieder gebrauchsfähig zu machen. Der neue Detektor soll diese Übelstände beseitigen. Zu diesem Zweck sind die Kristalle in einer luftdicht abgeschlossenen Kapsel eingeschlossen, wie die Abbildungen zeigen. Die Ringe c und d sind aus Isoliermaterial hergestellt, und der innere Hohlraum des Ringes c ist mit einer Schicht empfindlicher Kristallchen b lose angefüllt. Der Ring c ist, wie Abb. i zeigt, sehr -flach, so daß -,die Schicht von Kristallen sehr dünn wird. Dieselbe ist oben und unten durch eine dünne Blechscheibe a eingeschlossen. Die Metallscheiben a sind so groß wie der Isolierring c. Das Ganze ist schließlich durch einen beiderseits übergreifenden Ring d aus Isoliermaterial umgeben und dadurch zusammengehalten und versiegelt zu einem leicht auswechselbaren, handlichen, witterungsbeständigen Detektorelernent. Diese Art Detektorscheibe liegt im Apparat lose in einer Ausbohrung des Grundbrettes mit der unteren Metallfläche auf der Kopffläche des Kontaktbolzens e (Abb. i). Von oben wird dann die Feder f mit ihrem Kopf am freien Ende gegen die obere Metallfläche angedrückt und durch die Schraube g der Federdruck gegen den Detektor feiner eingestellt. Der Detektor kann auch, wie Abb. 3 zeigt, mehrere solche Kristallschichten übereinander besitzen. Die Schichten sind in diesem Falle aber immer durch voneinander isoliert liegende Metallbleche zu -trennen. Dieselben sind dann natürlich durch einen entsprechend größeren Isolierring d umschlossen.Electric wave crystal detector. The various crystal detectors for electrical waves always have the disadvantage that they are very easily insensitive, partly due to vibrations and during transport, partly due to atmospheric influences. It is then associated with a lot of loss of time to carefully readjust the detectors and make the receiver ready for use again. The new detector is supposed to remedy this problem. For this purpose, the crystals are enclosed in an airtight capsule, as the pictures show. The rings c and d are made of insulating material, and the inner cavity of the ring c is loosely filled with a layer of delicate crystals b. The ring c is, as Fig. I shows, very flat, so that the layer of crystals becomes very thin. It is enclosed above and below by a thin sheet metal disk a. The metal disks a are as large as the insulating ring c. The whole thing is finally surrounded by a ring d made of insulating material that overlaps on both sides and is thus held together and sealed to form an easily exchangeable, handy, weather-resistant detector element. This type of detector disk lies loosely in the apparatus in a hole in the base board with the lower metal surface on the top surface of the contact pin e (Fig. I). The spring f is then pressed from above with its head at the free end against the upper metal surface and the spring pressure against the detector is adjusted more finely by means of the screw g. As Fig. 3 shows, the detector can also have several such crystal layers on top of one another. In this case, however, the layers must always be separated by metal sheets that are isolated from one another. The same are then naturally enclosed by a correspondingly larger insulating ring d.
