Description
<Desc/Clms Page number 1>
Material am Draht festgehalten ist ; diese Umhüllung verhindert einerseits das Abfallen des Silberschwammes bei plötzlichen Stössen oder Erschütterungen und hält andererseits Partikolchen von Zink oder Quecksilber ab, in Berührung mit dem Silberschwamm zu kommen. Die Zellen 5 sind zum Teil mit einer Lösung von Ätzkali oder Ätznatron gefüllt. Beim Laden der Zellen 5 mittelst eines elektrischen Stromes absorbiert das schwammige Silber Sauerstoff, während Wasserstoff an den Zellenwandungen entweicht. Beim Entladen
EMI1.1
ein und das gebildete Six'oxyd wird wieder zu Silber reduziert. Bei nun wiederholtem Laden wird das Zink aus der Lösung an den amalgamierten Kupforüberzug der Zellen-
EMI1.2
zuvor, da es im Amalgam am Boden der Zellen enthalten war.
Sollten etwa Teile des am Kupferüberzug abgelagerten Zinks abfallen, dann gelangen diese in das Zinkamalgam am Boden der Zelle und sind wieder ausnützbar.
Die Zellen 5 sind in geeigneter Weise elektrisch verbunden ; eine Kontaktfläche ist die Stahlzelle selbst, der andere Kontakt ist dort, wo der mit der Silberkathode verbundene Eisendraht 11 durch den Boden der Zelle hervorragt. Wie demnach hervorgeht, sind die Zellen parallel geschaltet.
Vorliegende Erfindung ermöglicht die Herstellung einer wirksamen und dauerhaften, tragbaren elektrischen Handlampe, welche ein gutes und starkes Licht für einen längeren Zeitraum liefert und welche sich hauptsächlich für Minen und ähnliche Räume eignet, in denen ein offenes (frei brennendes) Licht nicht ohne Gefahr verwendbar ist. Der vollkommen abgeschlossene Lampenkörper macht die Lampe gefahrlos und schützt den Tnhalt : die Verwendung von Säuren ist vermieden.

Material is held on the wire; on the one hand, this covering prevents the silver sponge from falling off in the event of sudden bumps or vibrations and, on the other hand, keeps particles of zinc or mercury from coming into contact with the silver sponge. The cells 5 are partially filled with a solution of caustic potash or caustic soda. When the cells 5 are charged by means of an electric current, the spongy silver absorbs oxygen, while hydrogen escapes from the cell walls. When discharging
EMI1.1
and the six'oxide formed is reduced again to silver. With repeated charging, the zinc is transferred from the solution to the amalgamated copper coating of the cell
EMI1.2
before, as it was contained in the amalgam at the bottom of the cells.
If, for example, parts of the zinc deposited on the copper coating should fall off, these would end up in the zinc amalgam at the bottom of the cell and can be used again.
The cells 5 are electrically connected in a suitable manner; one contact surface is the steel cell itself, the other contact is where the iron wire 11 connected to the silver cathode protrudes through the bottom of the cell. As can be seen, the cells are connected in parallel.
The present invention enables the production of an effective and durable, portable electric hand lamp which provides a good and strong light for a longer period of time and which is mainly suitable for mines and similar rooms in which an open (freely burning) light cannot be used without danger . The completely enclosed lamp body makes the lamp safe and protects the contents: the use of acids is avoided.
