chemischer Reaktionen.chemical reactions.
Die vorliegende Erfindung betrifft die Vervollkommnung des bekannten Verfahrens der Tränkung von Löschpapier mit Chemikalien, um sie im Bedarfsfälle zur Herstellung von Lösungen bestimmten Gehaltes zu verwenden.The present invention relates to the improvement of the known method of FIG Impregnation of blotting paper with chemicals in order to produce them when necessary To use solutions of certain content.
Die Neuerung ist gekennzeichnet dadurch, dafs Löschpapierblätter oder -streifen einzeln mit verschiedenen auf einander einwirkenden Chemikalien getränkt werden; diese Blätter oder Streifen werden sodann unter Zwischenlegung neutraler Blätter, welche eine willkürliche Verbindung hindern sollen, zusammengelegt, zweckmäfsig durch eine Naht mit einander verbunden und in geeigneten Umhüllungen für den Gebrauch bereit gehalten, so dafs gleich grofse Stücke der fraglichen Blätter oder Streifen stets auch gleichwerthige Mengen der Reagentien enthalten, so dafs die gewünschten Reaktionen unmittelbar vor dem Gebrauch mit beliebig kleinen Mengen mittels Uebergiefsens von Wasser durchzuführen sind.The innovation is characterized by the fact that sheets or strips of blotting paper are used individually are soaked in various interacting chemicals; these sheets or strips are then interposed with neutral sheets, which an arbitrary Should prevent connection, put together, expediently by a seam with each other connected and kept ready for use in suitable wrappings, so that equally large pieces of the leaves in question or strips always contain equivalent amounts of the reagents, so that the desired Reactions are to be carried out immediately before use with arbitrarily small amounts by means of excess water.
Als Beispiele mögen dienen:The following may serve as examples:
Gleiche Gewichtsquanten von Ferridcyankalien und Ferrosulfat werden in gleichen Mengen Wasser gelöst und die gleiche ■ Anzahl von Löschpapierbogen mit je einer der Lösungen getränkt und getrocknet; die wechselweise mit neutraler Zwischenlage zusammengepackten Bogen werden nachher in Streifen geschnitten und durch Naht mit einander verbunden, so dafs stets genau die für die Reaktion (in diesem Falle einen blauen Farbstoff) benöthigten Gewichtsquanten der einzelnen Chemikalien in den Streifen bezw. in gleich grofsen Abschnitten derselben enthalten sind.Equal weight quanta of ferrous cyanide and ferrous sulfate are used in equal amounts Dissolved water and the same number of ■ sheets of blotting paper with one of the solutions soaked and dried; those alternately packed together with a neutral intermediate layer Arches are then cut into strips and connected to one another by seams, see above that always exactly the weight quanta required for the reaction (in this case a blue dye) the individual chemicals in the strips respectively. are contained in sections of equal size.
Für einen photographischen Entwickler möge folgendes Beispiel dienen:The following example may serve as a photographic developer:
120 g Natriumsulfit,
30 g Eikonogen,
50 g Pottasche,120 g sodium sulfite,
30 g egg-conogen,
50 g potash,
jedes einzeln in dem gleichen Quantum Wasser gelöst und in den Löschpapierstreifen einzeln imprägnirt, wird, wie beschrieben zusammengepackt und verwendet, einen genau abgestimmten Entwickler für belichtete Platten ergeben. each individually dissolved in the same quantity of water and individually in the blotting paper impregnated, is packed and used as described, a precisely matched one Developer for exposed plates.
Claims (1)
Löschpapierblätter oder -streifen, welche derart einzeln mit verschiedenen auf einander einwirkenden Chemikalien getränkt und unter Zwischenlegung neutraler Blätter oder Streifen zusammengelegt und zu einem Ganzen verpackt sind, dafs sie es ermöglichen, die gewünschten Reaktionen unmittelbar vor dem Gebrauch in beliebig kleinen Mengen durch Uebergiefsen mit Wasser durchzuführen.Patent claim:
Sheets or strips of blotting paper soaked individually with different chemicals that act on each other and folded together with the interposition of neutral sheets or strips and packed into a whole, that they allow the desired reactions to be carried out in any small quantities immediately before use by pouring water over them perform.
