KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Zwischenglieder der Erneuerungspatronen ■ für Atmungsvorrichtungen bestehen zumeist aus einem Behälter, vorzugsweise aus einer Blechschale, und aus einem Drahtnetzdeckel. Um zu verhindern, daß die in der Schale ausgebreiteten Stoffe beim Kippen der Schale nach einer Seite rutschen, wodurch die wirksame Oberfläche der chemischen Schicht in unerwünschter Weise verringert werdenThe intermediate links of the replacement cartridges ■ for breathing devices mostly exist from a container, preferably from a sheet metal shell, and from a wire mesh lid. In order to prevent the spread out fabrics in the tray from sliding to one side when the tray is tilted, whereby the effective surface area of the chemical layer can be undesirably reduced
ίο würde, hat man bereits vorgeschlagen, die Schalen durch Trennwände (Rippen, Leisten o. dgl.) in einzelne Felder zu teilen.ίο, one has already suggested that Dividing trays into individual fields by means of partitions (ribs, strips, etc.).
Der Gegenstand der Erfindung besteht nun darin, zu dem gleichen Zwecke nicht die Schalen mit Trennwänden zu versehen, sondern die Drahtnetzdeckel so auszugestalten, daß sie durchgedrückte, in das innere der Schalen reichende Rippen aufweisen.The object of the invention is now, for the same purpose, not the To provide bowls with partition walls, but to design the wire mesh cover in such a way that that they have pressed ribs reaching into the interior of the shells.
Diese Neuerung bietet dem Bekannten gegen-This innovation offers the familiar to
ao über wesentliche Vorteile, die sowohl in der Herstellung der Patronen wie auch in der technischen Wirkung liegen. Bei der Herstellung der mit Rippen versehenen Schalen macht sich nämlich der Ubelstand bemerkbar, daß durch das Pressen oft Risse im Blech entstehen, durch die die flüssige Kalilauge, welche sich bei der Erneuerung der Atmungsluft in der Patrone bildet, hindurchfließen würde. Ferner hat der Erfindungsgegenstand vor Behältern, bei denen die Schalen mit Trennwänden versehen sind, den Vorzug, daß sich Luftwirbel bilden, durch die eine innigere Berührung der Luft mit den Chemikalien erzielt wird.ao about essential advantages, both in the manufacture of the cartridges as well as in the technical effect. Makes in the manufacture of the ribbed bowls namely, the disadvantage is noticeable that cracks often arise in the sheet metal as a result of the pressing, through which the liquid potassium hydroxide solution, which is in the renewal of the breathing air the cartridge forms, would flow through it. Furthermore, the subject matter of the invention has in front of containers, in which the shells are provided with partitions, the advantage that there are air vortices through which a closer contact between the air and the chemicals is achieved.
Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht. Fig. 1 stellt eine solche Patrone im senkrechten Längsschnitt dar; Fig. 2 zeigt ein mit durchgedrückten Rippen versehenes Sieb und Fig. 3 eine für das Sieb der Fig. 2 geeignete ■— trennwandlose — Schale.The invention is illustrated by way of example in the drawing. Fig. 1 illustrates a such a cartridge in a vertical longitudinal section; Fig. 2 shows a with depressed Ribbed sieve and FIG. 3 a suitable for the sieve of FIG. 2 without a partition wall - Peel.
Jede Schale α von runder, ovaler oder langgestreckter Form aus blechartigem, gelochtem oder drahtnetzartigem Stoffe ist mit einem Drahtnetz b abgedeckt. Die Innenseite des Drahtnetzdeckels b ist durch eine Anzahl von durchgedrückten Rippen d in kleinere Felder aufgeteilt, und diese Rippen reichen in das Innere der mit geeigneten trockenen Chemikalien c, z. B. Ätzkalikörnern und Ätznatronkörnern, angefüllten Schalen. Eine Reihe solcher aus Schale und Drahtnetz bestehender Chemikalienträger wird in einem Behälter von geeigneter Form untergebracht und dadurch zu einer Erneuerungspatrone e vereinigt.Each shell α of round, oval or elongated shape made of sheet-like, perforated or wire-mesh-like materials is covered with a wire mesh b . The inside of the wire mesh cover b is divided into smaller fields by a number of pressed-through ribs d , and these ribs extend into the interior of the c, e.g. B. caustic potash grains and caustic soda grains, filled shells. A number of such chemical carriers, consisting of a bowl and a wire mesh, are placed in a container of suitable shape and thereby combined to form a replacement cartridge e .
