Description

Verwendung der nach dem Verfahren gemäß Patent 409505 erhaltenen Legierungen. Zusatz zum Patent 409505")-. *) Früheres Zusatzpatent .1c z c35. Die nach dem Verfahren gemäß Patent ¢09505 erhaltenen sehr harten und zähen Legierungen aus Wolfram und Platin bei gleichzeitigem Gehalt von etwas Kohlenstoff sind, wie sich herausgestellt hat, nicht nur für. Goldfederspitzen, sondern, auch für die Spitzen von Grammophonnadeln und Kompaßpinnen besonders geeignet. Während die ;gewöhnlichen Stahlnadeln schon nach drei- bis sechsmaligem Gebrauch abgeschliffen sind, hat eine Nadel, deren Spitze aus der beschriebenen Legierung besteht, das Abspielen mehrerer hundert Platten ausgehalten, ohne daß sich die Spitze verändert hat.Use of the alloys obtained by the process of patent 409505. Addition to patent 409505 ") -. *) Former additional patent .1c z c35. The one after the process according to patent [09505] obtained very hard and tough alloys of tungsten and It turned out that they are platinum with some carbon at the same time has, not just for. Gold nib tips, but also for the tips of gramophone needles and compass spiders are particularly suitable. While the ordinary steel needles do sanded off after three to six uses, a needle has its point consists of the alloy described, playing several hundred records endured without the tip changing.
