: Das in der Patentschrift 168717 beschriebene Verfahren zur Regenerierung der Atmungsluft besteht darin, daß die durch Einwirkung der Atmungsgase auf Superoxyde von der Zusammensetzung des Natriumsuperoxyds in-: The one described in Patent 168717 Process for the regeneration of the breathing air consists in that the by action the respiratory gases on superoxide on the composition of the sodium superoxide in

. ■ weiterem Studium der Wirkungsweise anderer Superoxyde zeigte es sich jedoch, daß der gemäß Patentschrift 168717 erforderliche Rest- oder Reservesauerstoff auch langsam entwickelt werden kann und namentlich zu diesem Behufe ebenfalls die Exhalationsprodukte herangezogen werden können, so daß bei geeigneter Zusammensetzung der Alkalisuper-. ■ further study of the way others work Superoxyde it was found, however, that the residual required according to patent 168717 or reserve oxygen can also be developed slowly and especially to this The exhalation products can also be used, so that when appropriate Composition of the alkali super-
ao oxyde mindestens jene Menge Sauerstoff aus den Atmungsprodukten regeneriert werden kann, welche bei ihrer Bildung verbraucht wurde.ao oxyde at least that amount of oxygen can be regenerated from the respiratory products which was consumed in their formation.
In diesem Falle erfolgt die Regenerierung überdies in genau dem gleichen Tempo als der Verbrauch. Zu diesem Behufe eignen sich jene Superoxyde, welche einerseits analog dem Natriumsuperoxyd mit ,-Wasser'■ .und Kohlensäure reagieren, andererseits aber eine größere Anzahl abspaltbarer Sauerstoffatome, bezogen auf die gleiche Anzahl Metallatome, enthalten. Beispielsweise sind die Reaktionsgleichungen bei Verwendung von Kaliumsuperoxyd (Kaliumtetroxyd) folgende:In this case, moreover, the regeneration takes place at exactly the same rate as the consumption. For this purpose those super oxides are suitable, which on the one hand analog the sodium peroxide with "water" and Carbonic acid react, but on the other hand a larger number of removable oxygen atoms, based on the same number of metal atoms. For example are the reaction equations when using potassium peroxide (potassium tetroxide) the following:
X2O4 +CO2 = K2 CO3 + 3O 3S X 2 O 4 + CO 2 = K 2 CO 3 + 3O 3S
K2O4 + H2O --2KOH+ 3 O. K 2 O 4 + H 2 O -2KOH + 3 O.
Es wird also in diesem Falle die 1 1J2 fache Menge, welche in der Kohlensäure, und die 3 fache Menge Sauerstoff, welche im Wasser gebunden ist, in elementarer Form regeneriert.It is thus in this case, the 1 1 J 2 times the amount which is regenerated in the carbonic acid, and 3 times the amount of oxygen which is bound in the water in elemental form.
Beim Kaliumnatriumsuperoxyd oder einem entsprechenden Gemenge der beiden Alkalisuperoxyde sind die Gleichungen folgende:In the case of potassium sodium peroxide or a corresponding mixture of the two alkali peroxides the equations are as follows:
Na KO3 + CO2 = Na KCO3 + O2 Na KO3 + H2O = NaOH+ KOH + O2, Na KO 3 + CO 2 = Na KCO 3 + O 2 Na KO 3 + H 2 O = NaOH + KOH + O 2 ,
so daß auch in diesem Falle der in den Atmungsprodukten gebundene Sauerstoff vollständig regeneriert wird.so that in this case, too, the oxygen bound in the respiratory products is complete is regenerated.
Bei Anwendung dieses Verfahrens auf einen zum Atmen in mit irrespirablen Gasen erfüllten Räumen dienenden Apparat ist dieser gekennzeichnet durch einen Behälter (Büchse) mit darin eingelagertem geeigneten höheren Alkalisuperoxyd, beiderseits durch FilterkämmernWhen using this procedure on one to breathe in filled with irresponsible gases The device used for space is marked by a container (can) with suitable higher alkali peroxide stored therein, through filter combs on both sides

Ja, es · kann sogar dieser Sack wegfallen und somit direkt das Gasgemenge, welches einen Raum erfüllt, in dem ein Brand stattfindet oder stattgefunden hat, und das daher Kohlensäure, Wasserdampf, Stickstoff und event. Kohlenoxyd in einem zum gewöhnliehen Atmen nicht mehr tauglichen Verhältnis zum noch vorhandenen Sauerstoff enthält, 'durch die Superoxydschicht geführt und nach ' Absorption der schädlichen Bestandteile und Regenerierung des in dem Superoxyd gebundenen Sauerstoffes in die Lunge einge- ao atmet werden.

Yes, even this bag can be omitted and thus directly the gas mixture, which fills a room in which a fire is taking place or has taken place, and that therefore carbonic acid, water vapor, nitrogen and possibly. Carbon oxide in one to be used Breathing contains an unsuitable proportion to the oxygen that is still present, 'passed through the superoxide layer and after' absorption of the harmful ingredients and Regeneration of the oxygen bound in the superoxide in the lungs be breathed.
