KLASSE 55: Papiekkabiukation.CLASS 55: Papiekabiukation.
Patentirt im Deutschen Reiche vom io. Juni 1892 ab.Patented in the German Empire by the io. June 1892.
Die Makulatur wird mit Petroleum imprägnirt. Durch diese Operation wird die Druckerschwärze derart aufgeweicht, dafs man im Stande ist, das zerkleinerte und infolge seines eigenen Fettgehaltes mit dem Petroleum verbundene Papier durch Kochen mit kaustischer Soda vollständig zu verseifen, so dafs sich die Schwärze nunmehr durch Auswaschen mit Seifenlauge vollständig, wie beim Waschen von Zeugen, aus der Makulatur entfernen läfst.The waste is impregnated with petroleum. Through this operation, the Printing ink so softened that one is able to cut the crushed and consequently its own fat content associated with the kerosene by cooking with caustic To completely saponify soda, so that the blackness is now washed out Can be completely removed from the waste with soapy water, as when washing witnesses.
Die derart wieder weifs gewordene Makulatur kann nun ebenso wie frische Papiermasse zur Herstellung neuen Druckpapiers verwendet werden. ■The waste, which has become white again in this way, can now just as well as fresh paper pulp used to make new printing paper. ■
Wollte man etwa Makulatur ohne vorherige Behandlung mit Petroleum mit kaustischer Soda und.Seife behandeln, so würde man nur eine schmutzige, mit der Schwärze innig verbundene Masse erhalten, die keineswegs mehr zu Papier verwendbar und ganz werthlos sein würde.If you wanted to waste paper without prior treatment with petroleum with caustic Treat soda and soap, that's just how you would a dirty mass, intimately connected with the blackness, is no longer at all usable for paper and would be completely worthless.
Patenτ-Anspruch:Patenτ claim:
Verfahren, bedrucktes Papier — Makulatur — durch Imprägniren mit Petroleum derart vorzubereiten, dafs die Druckerschwärze dadurch aufgeweicht, alsdann beim Kochen des zerkleinerten Papiers mit kaustischer Soda durch ihren Fettgehalt verbunden, mit dem Petroleum verseift und beim Auswaschen mit Seifenlauge vollständig entfernt werden kann, so dafs die Makulatur neuerdings zu Druckpapier verwendbar ist.Process to prepare printed paper - waste - by impregnation with petroleum in such a way, that the printing ink is softened as a result, then when the crushed one is boiled Papers with caustic soda are connected by their fat content to petroleum saponified and can be completely removed when washing with soapy water, so that the Paper waste has recently become usable for printing paper.
