Zusatz zum Patente 126135 vom 13. Februar 1900.Addendum to patent 126135 from February 13, 1900.

Patentiert im Deutschen Reiche vom 30. März 1905 ab. Längste Dauer: 12. Februar 1915.Patented in the German Empire on March 30, 1905. Longest duration: February 12, 1915.

Nach der Erfindung werden dem im D. R. P. 126135 beschriebenen, in einen hängenden Glühstrumpf eintretenden Gasluftstrom ein Strom oder mehrere Ströme von Gasluftgemischen derart zugefügt, daß die Ströme einander einhüllen und bei gleichen oder verschiedenen Geschwindigkeiten auch verschiedene Luftzumischungen haben...According to the invention, the one described in D. R. P. 126135, in a hanging Incandescent gas air stream entering a stream or several streams of gas air mixtures added so that the currents envelop each other and at the same or different Speeds also have different air admixtures ...

Bei Invertlampen, bei denen die Verbrennungsluft durch einen Zugzylinder dem Gas^v luftgemisch entgegengeführt wird, ist nicht an allen Stellen der Flamme ein gleich starkes Gegenprallen der äußeren Luft gegen das Gasluftgemisch vorhanden, vielmehr ist diesesIn Invertlampen in which the combustion air is led towards ^v-air mixture by a traction cylinder the gas is not at all points of the flame an equally strong counter-colliding against the outside air, the gas air mixture is present, but this is

¹S meist am unteren Saum der Flamme am stärksten. Hat nun der Gasluftstrom im ganzen Querschnitt gleiche Geschwindigkeit und gleiche Mischung von Gas und Luft, so kehrt sich die Flamme bei aufsteigender äußerer Verbrennungsluft sofort um, wenn die beiden Ströme den ganzen Strumpfquerschnitt ausfüllen. A^ersucht man die Aus- ¹ S mostly strongest at the lower edge of the flame. If the gas air stream has the same speed and the same mixture of gas and air over the entire cross-section, the flame reverses immediately when the external combustion air rises when the two streams fill the entire cross-section of the stocking. A ^ one asks for the

" trittsgeschwindigkeit zu vergrößern, so wird eine so bedeutende Gasmenge in den Strumpf eingeführt, daß das Gas nicht vollständig innerhalb des Strumpfes verbrennt und also zum Teil nutzlos verloren geht. Nach dem Hauptpatent wird deshalb das Gasluftgemisch in einer nicht den ganzen Querschnitt des Strumpfes ausfüllenden Säule in denselben' eingeführt."To increase the speed of the footsteps, such a significant amount of gas enters the stocking introduced that the gas does not burn completely inside the stocking and so partly useless is lost. According to the main patent, the gas-air mixture is therefore in a column that does not fill the entire cross-section of the stocking in the same ' introduced.

Bei diesem Verfahren wird indessen die 35 In this procedure, however, the 35th

Verbrennung an den Seiten und am Fuß des Glühstrumpfes leicht zu sehr herabgesetzt. Es ist daher wünschenswert, zwischen den zentralen, dort luftarm zu lassenden Strom und den Glühkörper noch einen oder mehrere Gasluftgemischströme einzuführen, die gegebenenfalls den ganzen Zwischenraum ausfüllen können, und den äußeren Schichten des Gasluftgemisches, die nicht bis zum unteren Rand der Flamme gelangen, mehr Luft beizumengen als den inneren Schichten, oder die äußeren Schichten mit geringerer Geschwindigkeit in den Strumpf eintreten zu lassen als die inneren Schichten. Wenn beide Ströme zusammen den . ganzen Querschnitt des Strumpfes an seiner Basis ausfüllen, ist es empfehlenswert, den äußeren Gasluftstrom mit ganz geringer Geschwindigkeit einzuführen, weil dann das am Rand in den Strumpf eintretende Gemisch noch verhältnismäßig leicht verbrennt' und ein Entweichen unverbrannten Gases möglichst vermieden wird.Burns on the sides and at the base of the mantle are slightly too reduced. It is therefore desirable between the central, there air-poor flow and to introduce one or more gas-air mixture streams into the incandescent body, which optionally can fill the whole gap, and the outer layers of the gas-air mixture, which do not go down to the bottom Get to the edge of the flame to add more air than the inner layers, or the to allow outer layers to enter the stocking at a slower rate than the inner layers. If both streams together the. whole cross section of the Filling the stocking at its base, it is recommended to use the external gas air flow to be introduced at a very low speed, because then it will be inserted into the stocking at the edge incoming mixture still burns relatively easily 'and an escape of unburned Gas is avoided as far as possible.

Das Entweichen unverbrannter Gase wird aber noch sicherer dadurch vermieden, daß man den inneren und äußeren Gasluftstrom so klein macht, daß sie zusammen noch einen erheblich geringeren Querschnitt haben als der Strumpf; dann ist auch ein Riechen der Flamme völlig zu vermeiden. Die Aufgabe, einen starken mittleren Gasluftstrom neben schwächeren seitlichen Strömen zu erzielen, hat man bei Invertlampen ohne GegenführungThe escape of unburned gases is avoided even more reliably in that one makes the inner and outer gas air stream so small that they together add up to a considerable amount have a smaller cross-section than the stocking; then there is also a smell of the Avoid flame entirely. The task of a strong medium gas air stream alongside To achieve weaker lateral currents, one has to do with invert lamps without a counter guide

Claims

the combustion air already z. B. tried to solve by the fact that the expanded mixing tube mouth was completed by a sieve provided with a free central passage opening, so that the gas-air mixture flows out of the central sieve opening at greater speed than that part of the gas-air mixture "which flows in through the sieve itself and the Or a burner head protruding into the incandescent body was connected to the mouth of the mixing tube, which is made up of several cells open on both sides or tubes of different lengths inserted into one another with the same axis, so that the gas-air mixture in several columns enveloping the burner head According to the invention, these known similar means are used to further develop the method according to the main patent in the manner indicated, in the case of the burners shown in FIG Arranged two injectors and two mixing tubes, one of which injector and its associated mixing tube introduces an inner air-poor gas-air column and the second introduces an air-rich gas-air mixture in a ring surrounding this column through the burner head into the mantle. The outer stream can be given a slower speed than the inner one. In FIG. 2, the injector, which in FIG. 1 is slightly inclined to the stocking base, has an inclination of 900 to the stocking base. In the burner shown in Fig. 3, there is only one injector and one mixing tube. Inside the mixing tube, a second narrower tube is coaxially arranged and led to the mixing tube opening, so that the inner gas air layers richer in gas near the gas nozzle are protected from diffusion with the outer gas air layers on their way to the burner head. In the case of the burner according to FIG. 4, too, two concentric mixing tubes are arranged. Here the gas nozzle consists of a larger central passage opening which supplies the gas for the inner mixing tube, and a number of smaller passage openings which are arranged concentrically around this large central opening and which supply the gas for the outer mixing tube. In all figures, α denotes the gas supply pipe, b the air inlets for the mixed air, c the gas nozzle or gas nozzles, e the mixing tubes / the glow fabric and g the bell jar surrounding the flow. Godfather ν τ claims:

1. A method for producing incandescent gas light according to Patent 126135, characterized in that that apart from the air-poor gas-air mixture stream flowing out of the center of the burner head, one or more of the the latter enveloping streams of a gas-air mixture richer in air into the incandescent body to be introduced.

2. The method according to claim 1, characterized in that the inner air-poor • Gas-air mixture flow at a greater speed than that or those surrounding it air-rich gas-air mixture- 75 streams is introduced into the incandescent body.

3. Burner for performing the method according to claim 1 and 2, characterized by two independent mixing tubes penetrating each other at their mouth in such a way that the one in one mixing tube The gas-air mixture stream generated envelops the stream generated in the other mixing tube and the gas-air mixture streams with it different air admixture and different speed in the incandescent body to be introduced.

4. Burner for carrying out the method according to claim 1 and 2, characterized in that a narrower pipe is inserted in a wide mixed go pipe coaxially with this, the upper mouth of which is close to the nozzle opening (c) , so that in the The gas-air mixture flow generated in the insert tube has less air than the gas-air mixture flow which surrounds it and is generated in the further mixing tube.

5. Burner according to claim 4, wherein to generate the air-poor and of the air-rich gas-air mixture stream enveloping it, a central nozzle opening above the insert tube and several Nozzles standing in a circle around this nozzle opening into the annular space between the insert tube and the mixing tube are arranged.
