Description

Gegenstand des Patents 879 651 ist eine Vorrichtung zum Regeln der Wärme in Atemschutzgeräten mit Erneuerung der Atemluft in Alkali-oder Alkalisuperoxydpatronen, bei der die Patrone von einem Kühlmantel, insbesondere einem Flüssigkeitsmantel, umgeben ist, dessen Kühlwirkung auf dem Verdampfen flüssiger oder dem Schmelzen fester Stoffe beruht. Der Kühlmantel kann ein ringförmiges Gefäß darstellen, in das die Patrone hineingesteckt ist. Der Kühlmantel kann auch durch aufsaugende Stoffe gebildet sein, die mit Flüssigkeiten getränkt sind und entweder für sich um die Patrone herumgelegt oder in einem ringförmigen, die Patrone aufnehmenden Gefäß untergebracht sein können. Die aufsaugenden Stoffe können mit einem Vorratsbehälter für Flüssigkeiten z. B. mit Hilfe eines Dochtes in Verbindung stehen, so daß die verdampfte Flüssigkeit ständig ersetzt wird.The subject of patent 879 651 is a device for regulating the heat in breathing apparatus with renewal of the breathing air in alkali or alkali peroxide cartridges, in which the cartridge is surrounded by a cooling jacket, in particular a liquid jacket, the cooling effect of which is based on the evaporation of liquid or the melting of solid substances is based. The cooling jacket can represent an annular vessel into which the cartridge is inserted. The cooling jacket can also be formed by absorbent substances which are soaked with liquids and which can either be placed around the cartridge by themselves or housed in an annular vessel that holds the cartridge. The absorbent substances can with a reservoir for liquids z. B. be in communication with the help of a wick, so that the evaporated liquid is constantly replaced.

Diese Vorrichtung wird erfindungsgemäß dadurch weiter ausgebildet und verbessert, daß der Kühlmantel aus einer oder mehreren Lagen von gegebenenfalls mit durchlaufenden Längsöffnungen versehener Wellpappe gebildet wird, die auf beiden Seiten von glatten Papplappen überdeckt sind, so daß Kanäle entstehen, die das Aufsaugen von Kühlflüssigkeit durch den Mantel erleichtern.This device is further developed according to the invention and improves that the cooling jacket consists of one or more layers of optionally Corrugated cardboard provided with continuous longitudinal openings is formed, which on both Pages are covered by smooth cardboard, so that channels are created that absorb of coolant through the jacket.

In der Zeichnung sind zwei Ausführungsformen der neuen Patrone schematisch im Schnitt dargestellt.In the drawing, two embodiments of the new cartridge are schematically shown in section.

Innerhalb der Patrone, deren Mantel r nur in einem Bruchstück sichtbar ist, ist gekörntes Alkalihydroxyd oder Alkalisuperoxyd 2 untergebracht. Dabei ist die Patrone von einem Mantel umgeben, der aus einer gegebenenfalls grobporigen Wellpappe 3 gebildet ist, die auf beiden Seiten von nicht gewellten Papplagen .4 bedeckt ist, so daß kapillarartig wirkende Aufsaugkanäle 5 und 6 für Kühlflüssigkeiten entstehen.Inside the cartridge, only a fragment of the jacket r is visible is, granular alkali hydroxide or alkali peroxide 2 is housed. It is the cartridge is surrounded by a jacket made of corrugated cardboard with possibly large pores 3 is formed, which is covered on both sides by non-corrugated cardboard sheets .4, so that capillary-like suction channels 5 and 6 arise for cooling liquids.

Abb.2 zeigt eine Ausführungsform, deren Mantel aus doppelten Lagen von Wellpappe besteht, wobei die Wellen gegeneinandergerichtet sind, so daß zur Patrone hin und nach außen die glatten Seiten der Wellpappe liegen. In diesem Falle ist die Verwendung besonderer, nicht gewellter Papplagen überflüssig. Die Wehpappen können zur Erhöhung der Kühlwirkung und der Aufsaugfähi:gkeit noch mit durchlaufenden Längsöffnungen 7 versehen sein. Dabei können, wie dies im unteren Teil der Zeichnung angedeutet ist, die Wellenberge aufeinanderliegen, sie können aber auch, wie dies der obere Teil der Abb. 2 zeigt, in den Wellentälern des Gegenstückes liegen.Fig.2 shows an embodiment whose jacket is made of double layers consists of corrugated cardboard, the waves are directed against each other, so that for Cartridge face back and forth against the smooth sides of the corrugated cardboard. In this case the use of special, non-corrugated cardboard layers is superfluous. The heraldic cardboard can be used to increase the cooling effect and the absorbency with continuous Longitudinal openings 7 may be provided. You can do this, as shown in the lower part of the drawing is indicated, the wave crests lie on top of each other, but they can also, like this the upper part of Fig. 2 shows, lie in the wave troughs of the counterpart.
