Kohlenelektrode für Flammenbogenlampen.Carbon electrode for flame arc lamps.
Patentiert im Deutschen Reiche vom 11. Mai 1913 ab.Patented in the German Empire on May 11, 1913.
Es ist bekannt, daß Titanverbindungen einen sehr hellen, aber unruhigen Lichtbogen geben, und daß Fluorverbindungen eine beruhigende Wirkung haben, und es ist auch vorgeschlagen worden, um einen zugleich hellen und ruhigen Lichtbogen zu erhalten, beständige Titanfluorverbindungen zu verwenden, die natürlich noch ein anderes Metall außer Titan enthalten müssen. Kalziumtitanfluoride für gelbes und Certitanfluorid für weißes Licht geben, nur mit Kohle verarbeitet, im allgemeinen sehr brauchbare Elektroden.It is known that titanium compounds give a very bright but restless arc, and that fluorine compounds have a sedative effect, and it is also suggested in order to obtain a bright and calm arc at the same time, permanent titanium fluorine compounds to use, which of course must contain another metal besides titanium. Calcium titanium fluoride for yellow and Certitanfluorid for giving white light, only processed with charcoal, in general very useful Electrodes.
Unter gewissen Bedingungen aber, besonders wenn die Elektroden langsam verbraucht wer-Under certain conditions, however, especially when the electrodes are slowly being used up
1S den, z. B. in Lampen mit eingeschlossenem Lichtbogen, dampft das Titanfluorid des Erdmetalles schon in einiger Entfernung von dem Lichtbogen aus, die Dämpfe treten ungleichförmig in den Lichtbogen ein und machen ihn unruhig. Es ist nun vorgeschlagen worden, die Unruhe durch eine Alkaliverbindung, wie Kalium- oder Natriumtitanfluorid, zu beheben, das bei geringerer Temperatur schmilzt als die Titanfluoride der Erdmetalle und letztere in Suspension hält. 1 S den, e.g. B. in lamps with an enclosed arc, the titanium fluoride of the earth metal evaporates at some distance from the arc, the vapors enter the arc unevenly and make it restless. It has now been proposed to remedy the unrest by means of an alkali compound, such as potassium or sodium titanium fluoride, which melts at a lower temperature than the titanium fluorides of the earth metals and keeps the latter in suspension.
Die Natrium- und Kaliumverbindungen geben aber dem Bogen eine gelbe Farbe, die z. B. bei Straßenbeleuchtung sehr störend ist. Erfindungsgemäß wird daher durch eine Bariumverbindung die gelbe Farbe unterdrückt und ein mehr tageslichtähnliches Licht erzeugt. Eine gute Elektrode erhält man z. B. aus:However, the sodium and potassium compounds give the sheet a yellow color, which z. B. is very annoying in street lighting. According to the invention is therefore by a barium compound suppresses the yellow color and creates a more daylight-like light. A good electrode is obtained e.g. B. from:
Certitanfluorid 35 Prozent,Certitanfluorid 35 percent,
Kaliumtitanfluorid 10Potassium Titanium Fluoride 10
Bariumfluorid 10 -Barium fluoride 10 -
Kohle 45 - .Coal 45 -.
Man hatte zwar schon früher Bariumverbindungen in Titanelektroden anzuwenden versucht, war aber durch die geringe Lichtausbeute abgeschreckt worden und hatte auch nicht versucht, sie neben Natrium- oder Kaliumverbindungen zu verwenden. Die Titanfluoride der Alkalimetalle haben aber auch die Eigenschaften, ätzende Dämpfe abzugeben, und werden daher für den Zweck, die Titanfluoride der Erdmetalle in Suspension zu halten, vorteilhaft durch andere Alkaliverbindungen ersetzt. Bewährt hat sich Natriumsilikat, Natriumborat, Natriumcarbonat, ■ Natriumwolframat und -molybdat. Auch Kaliumverbindungen, besonders Kaliumborat, haben sich bewährt. Ersetzt man die Titanfluoride durch diese letztgenannten Verbindungen, so muß man aber das Verhalten des Titanfluorides des Erdmetalles zu den anderen Bestandteilen etwas verändern. Eine gute Elektrode erhält man z. B. aus:Barium compounds had to be used in titanium electrodes before tried, but was deterred by the low light output and also had did not try to use them alongside sodium or potassium compounds. The titanium fluorides However, the alkali metals also have the properties of emitting corrosive vapors, and are therefore used for the purpose of the titanium fluoride to keep the earth metals in suspension, advantageously through other alkali compounds replaced. Sodium silicate, sodium borate, sodium carbonate, ■ sodium tungstate have proven useful and molybdate. Also have potassium compounds, especially potassium borate proven itself. If the titanium fluorides are replaced by these last-mentioned compounds, so but one has to determine the behavior of the titanium fluoride of the earth metal to the other components change something. A good electrode is obtained e.g. B. from:
Certitanfluorid 37 Prozent,Certitanfluorid 37 percent,
Bariumfluorid 7Barium fluoride 7
Natriumsilikat 3Sodium silicate 3
Natrium wolf ramat. . 3Sodium wolf ramat. . 3
Kohle 50 ■ - .Coal 50 ■ -.
Statt der Kohle verwendet man mit Vorteil ein aus der Literatur bekanntes Gemisch von Ruß und Koks. 6 Teile Ruß und 44 Teile gepulverter Koks geben eine gute Kohlemischung.Instead of the coal, a mixture of known from the literature is advantageously used Soot and coke. 6 parts of carbon black and 44 parts of powdered coke make a good coal mix.
Auch bei starken Abweichungen von den angegebenen Verhältnissen erhält man noch gute Elektroden.Even with strong deviations from the specified ratios, you still get good electrodes.
