Description

Rohrförmiges Zwischenstück mit eingebautem Mikrophon Gegenstand vorliegender Erfindung weist eine wesentliche Verbesserung der Konstruktion des Hauptpatents 667 787 auf, und zwar in bezug ,auf die Form des Mikrophons und dessen Einbau in das Rohrzwischenstück.Tubular Intermediate Piece with Built-in Microphone The subject of the present invention provides a substantial improvement in the construction of the main patent 667 787 , specifically in relation to the shape of the microphone and its installation in the tubular intermediate piece.

Der Gegenstand des Hauptpatents ist ein zwischen Gasmaske und Gasfilter rinschraubbares rohrförmiges Zwischenstück, in dessen Durchgangskanal ein den Kanalquerschnitt nur teilweise ausfüllendes Mikrophon ;aufgehängt ist, dessen Zuleitungen gasdicht durch die Rohrwandungen durchgeführt sind.The subject of the main patent is between a gas mask and a gas filter Screwable tubular intermediate piece, in the through-channel of which a channel cross-section Only partially filling microphone; is suspended, its feed lines are gas-tight are carried out through the pipe walls.

Der Gegenstand des Hauptpatents wird gedanklich nicht verändert, sondern nur konstruktiv für die praktische Nutzbarmachung verbessert, und zwar insofern, als die seither in bezug auf den Diurchlaß genügender Atemluft noch bestehenden geringen Widerstände beseitigt werden.The subject matter of the main patent is not changed, but rather only structurally improved for practical utilization, to the extent that than the air that has existed since then with regard to the passage of sufficient breathing air low resistances can be eliminated.

Bei dem Gegenstand vorliegender Erfindung ist ein ringförmiges Mikrophon so in die Wandung des Zwischenstückes eingebaut, daßeine Zylindermantelm-embran an die Stelle eines Teiles der Kanalwandung tritt oder diese Kanalwandung selbst bildet.In the subject matter of the present invention is an annular microphone so built into the wall of the intermediate piece that a cylinder jacket takes the place of part of the duct wall or this duct wall itself forms.

Diese Verbesserung, also der Einbau eines rohrförmigen Zwischenstückes mit angepaßtem Ringmikrophon, beseitigt die seither bestehenden geringen Atmungsschwierigkeiten völlig und schafft in bezug auf das Durchströmen der Atmungsluft .eine überzeugend einfache und wirksame Lösung mit dem weiteren. Vorteil, daß der Abstand zwischen Maske und Gasfilter, der durch das Einsetzen des Zwischenstückes an und für sich vergrößert wird, nunmehr in engen und handlichen Grenzen bleibt.This improvement, i.e. the installation of a tubular intermediate piece with adapted ring microphone, eliminates the minor breathing difficulties that have existed since then completely and creates a convincing effect with regard to the flow of the breathable air simple and effective solution with the further. Advantage that the distance between Mask and gas filter, which by inserting the adapter in and of itself is enlarged, now remains within narrow and manageable limits.

Ringmikrophone an sich sind als bekannt vorausgesetzt. Völlig neu ist jedoch der Gedanke des Einbaues solcher Ringmikrophone in ein rohrförmiges Zwischenstück laut Hauptpatent.Ring microphones per se are assumed to be known. Completely new however, the idea is to install such ring microphones in a tubular intermediate piece according to the main patent.

Die Verwendung eines Ringmikrophons und die Art seines Einbaues in das rohrförmige Zwischenstück ändert an den Zuleitungen und Kontakten nichts, so daß die Voraussetzungen des Hauptpatents bestehen bleiben.The use of a ring microphone and how to install it in the tubular intermediate piece does not change anything on the leads and contacts, see above that the requirements of the main patent remain.
