Description

Elektrische Heizwiderstände. Bekannt sind elektrische Heizkörper, deren Widerstandsdrähte aus. Eisen - oder Nickel oder aus Legierungen derselben miteinander oder anderen Metallen bestehen. Sie müssen, um Oxydationen zu vermeiden, möglichst luftdicht zwischen Glimmerplatten oder in hitzebeständige Massen eingebettet. werden. Nach vorliegender Erfindung sollen(nun)Heizwiderstände hergestellt werden, . die luftbeständig sind. Hierzu wird kohlenstofffreies Eisen je nach dem gewünschten spezifischen Widerstand mit Bormetall bis zu 2o Prozent legiert und dann in Stäbe gegossen. Diese Heizstäbe, frei auf Isolatoren gelegt - wenn gewünscht, auch in Heizmasse eingebettet -, geben dann einen luftbeständigen Heizkörper, der in sehr geringem Maße oxydiert und eine große Lebensdauer besitzt.Electric heating resistors. Electric radiators are known, their resistance wires. Iron or nickel or from alloys of the same with each other or with other metals. To avoid oxidation, you must Embedded as airtight as possible between mica sheets or in heat-resistant compounds. will. According to the present invention, heating resistors should (now) be produced, . that are air-resistant. This is done using carbon-free iron depending on the desired Specific resistance alloyed with boron metal up to 2o percent and then in rods poured. These heating rods, placed freely on insulators - if desired, also in Embedded heating mass - then give an air-resistant radiator, which is in very oxidizes to a small extent and has a long service life.

Ebenso wie Eisen kann auch Nickel oder eine Legierung von Eisen und Nickel durch Borzusatz in einen brauchbaren Heizkörper verwandelt werden.Just like iron, nickel or an alloy of iron and can also be used Nickel can be turned into a usable radiator by adding boron.
