PATENTAMT.PATENT OFFICE.
Die allgemein üblichen Stahlbürsten sowie . Bürsten mit anderen bisher verwendeten Metallborsten haben den Nachteil, daß sie gegen die Einwirkung der Feuchtigkeit der Luft nicht immer im gewünschten Maße widerstandsfähig sind, daß sie außerdem von Säuren und Al-.)■' kalien leicht angegriffen, brüchig gemacht und ^ unter Umständen ganz zerstört werden.The commonly used steel brushes as well. Brushes with other previously used metal bristles have the disadvantage that they do not protect against the effects of moisture in the air are always resistant to the desired extent that they are also resistant to acids and Al -.) ■ ' alkalis can be easily attacked, made brittle and, under certain circumstances, completely destroyed.
Diese Übelstände haben den Gedanken zu ίο der vorliegenden Erfindung gegeben, welche darin besteht, daß Drähte aus dem hochschmelzenden Metall Wolfram für solche Bürsten, Pinsel u. dgl. verwendet werden.These drawbacks have given the idea to ίο the present invention, which consists in using wires made of the refractory metal tungsten for such brushes, Brushes and the like can be used.
Es ist in neuerer Zeit durch die Erfordernisse der Glühlampenindustrie möglich geworden, Wolfram zu Drähten allerfeinster Durch- > messer nach den auch sonst in der Draht-herstellung üblichen Verfahren herzustellen, und zwar können je nach der Bearbeitungsart weiche, mittelharte und spröde Drähte hergestellt werden. Diese können in der üblichen Weise zu Bürsten, Pinseln u. dgl. vereinigt werden. Auch als Ersatz für Radiergummi, Schaber, Schwabber u. dgl. können derartige Bürsten bzw. pinseiförmige Bindungen von Wolframdraht verwendet werden.In recent times, the requirements of the incandescent lamp industry have made it possible to Tungsten to wires of the finest> diameter, similar to those used in wire production conventional methods, and depending on the type of processing, soft, medium-hard and brittle wires can be produced will. These can be combined in the usual way to form brushes, paint brushes and the like will. These can also be used as a replacement for erasers, scrapers, buffers and the like Brushes or pin-shaped bonds of tungsten wire are used.
Dieselben haben den Vorteil großer mechanischer Widerstandsfähigkeit in gleichem Maße wie den der Unangreifbarkeit durch Säuren, Laugen, Gase, Dämpfe u. dgl. (Bekanntlich wird das Wolfram nur durch ein Gemisch von Salpeter- und Flußsäure gelöst.)The same have the advantage of great mechanical resistance in the same Measures such as the invulnerability to acids, alkalis, gases, vapors and the like the tungsten is only dissolved by a mixture of nitric and hydrofluoric acid.)
