Legierung zum Hintergiessen von Galvanos und zur Herstellung von Stereotyp-und LetternmetaH.
Bisher war es üblich, zum Hintergiessen von Galvanos und zur Herstellung von Stereotyp-und Letternmetall eine Legierung von Blei, Antimon und Zinn zu verwenden.
Je nach dem Verwendungszweck war das Mischungsverhältnis von Blei, Zinn und Antimon verschieden. Es wurde nun gefunden, dass sich an Stelle des Zinns, welches in der Legierung zur Erzielung der Leichtflüssigkeit und des porenfreien Gusses verwendet wurde, mit Vorteil Quecksilber verwenden lässt, und zwar ist die Menge des Quecksilbers, welche dem Metall zur Erzielung der gleichen Eigenschaften zugesetzt werden muss, bedeutend geringer als die der bisher verwendeten Menge von Zinn. Der so erhaltenen Legierung muss, um der Abnutzung beim Druck entgegenzuwirken, ein entsprechendes Härtungsmittel zugesetzt werden. Als solches Mittel hat sich Arsen erwiesen. Dem Arsen kommt hinsichtlich der Härte von Blei und Bleilegierungen bekanntlich die gleiche Eigenschaft, wie dem Antimon zu.
Als Vorteil ergibt sich, dass die Menge des der Legierung zuzusetzenden Arsens bedeutend geringer ist, als die des Antimons. Praktische Versuche haben ergeben, dass mit einer Legierung, welche beispielsweise aus 99'4% Blei, 0'4% Arsen, 0'2% Quecksilber besteht, die gleiche Anzahl von Abzügen auf Rotations-und anderen Druckmaschinen erzielt werden kann, wie mit einer Legierung aus 75% Blei, 18% Antimon, 7% Zinn.
-PATENT-ANSPRÜCHE : I. Legierung zum Hintergiessen von Galvanos und zur Herstellung von Stereotypund Letternmetall, dadurch gekennzeichnet, dass in einer Blei-Antimon-Zinnlegierung das bisher verwendete Zinn ganz oder teilweise durch Quecksilber ersetzt wird.

Alloy for back casting of electroplants and for the production of stereotype and letter metaH.
Up to now it has been customary to use an alloy of lead, antimony and tin for back-casting of electroplants and for the production of stereotype and letter metal.
The mixing ratio of lead, tin and antimony was different depending on the purpose. It has now been found that instead of the tin, which was used in the alloy to achieve the light fluidity and the pore-free casting, mercury can advantageously be used, namely the amount of mercury which is added to the metal to achieve the same properties must be, significantly less than the amount of tin previously used. An appropriate hardening agent must be added to the alloy obtained in this way in order to counteract wear and tear during printing. Arsenic has proven to be such an agent. As is well known, arsenic has the same property as antimony with regard to the hardness of lead and lead alloys.
The advantage is that the amount of arsenic to be added to the alloy is significantly less than that of antimony. Practical tests have shown that with an alloy consisting, for example, of 99.4% lead, 0.4% arsenic, 0.2% mercury, the same number of prints can be made on rotary and other printing machines as with one Alloy of 75% lead, 18% antimony, 7% tin.
-PATENT CLAIMS: I. Alloy for back casting of galvanos and for the production of stereotype and letter metal, characterized in that in a lead-antimony-tin alloy the previously used tin is wholly or partly replaced by mercury.
