Description

Masse zum Herstellen von Erstarrungskernen Zusatz zum Patent 705 451 Die Erfindung betrifft eine Weiterentwicklung des Gegenstandes des Patents 705 45I, welches eine Masse zum Herstellen; von Erstarrungskernen schützt, die sich durch Leimgallerte kennzeichnet, die aus etwa 3oo Teilen tierischen Leimes von möglichst hohem Glutingehalt oder gleichwertigen Leimes in etwa 7oo Teilen warmen Wassers entstanden ist und Desinfektionsmittel, wie Karbolsäure, Kreosot, und ein bakterientötendes Anilinfärbmittel enthält. Bei der Anwendung dieser Masse soll nach dem Hauptpatent dem mit der Masse versetzten Kernsand Öl zugesetzt werden. Nach der Erfindung ist die Masse nach dem Hauptpatent bei möglichst niedriger Temperatur vor dem Erstarren mit trocknenden oder nichttrocknenden Ölen oder Fetten emu.lgiert, so daß sich ein nachträglicher Ölzusatz zu der Kernsandmasse erübrigt. Der Ölbedarf wird hierdurch zwar etwas vergrößert, jedoch ergibt sich der große Vorteil, daß die Masse eine bedeutend erhöhte Lagerfähigkeit besitzt und auch im Hochsommer bei jeder Witterung und Temperatur lagerfähig und versandfähig ist. Hinsichtlich der Herstellung von Kernen bestehen: die gleichen Vorteile wie bei der Masse nach dem Hauptpatent.Mass for the production of solidification cores Addendum to patent 705 451 The invention relates to a further development of the subject matter of patent 705 45I, which is a mass for production; from solidification cores, which is characterized by glue jelly, which is made from about 300 parts of animal glue with the highest possible glutin content or equivalent glue in about 700 parts of warm water and contains disinfectants such as carbolic acid, creosote and a bactericidal aniline dye. When using this mass, according to the main patent, oil should be added to the core sand mixed with the mass. According to the invention, the mass according to the main patent is emulated with drying or non-drying oils or fats at the lowest possible temperature before solidification, so that subsequent oil addition to the core sand mass is unnecessary. The oil requirement is thereby increased somewhat, but there is the great advantage that the mass has a significantly increased shelf life and can be stored and shipped even in midsummer in any weather and temperature. With regard to the production of cores: the same advantages as with the mass according to the main patent.
