Specification of Letters Patent. Patente d June 3, 1913. Application filed May 13:; 191a Serial No. 696,971.,

To all whom, it may concern:

Be it known that we JONATHAN ZnNNEoK' and KARL VQLLMER, subjects, respectively, of the King of Wurttemberg and the King of Prussia, residing, respectively, at Danzig- Langfuhr and Jena, Germanyj have 1n-- .vented new and useful Improvements in the Production. of Long Stable Electric 'Arcs,

-.Of which the following is a specification.

In the specification of Letters Patent No.

'930,238 of August 3, 1909, granted to Messrs. Schtinherrand Hessberger, is described the production of long stable-electric arcs.

Our present invention relates to improvements in the reduction of the said arcs, whereby the e lciency of the said arcs for producing reactions in gases is considerably increased.

According to the present invention the are produced as describedin the-said Lettars Patent when employing an enveloping currentoof gas possessing awhirling motion is subjected to the action of a magnetic field and the best results are obtained when .the gases are introduced into the tubular furnace tangentially, so that a whirlingmotion is produced as described in the said specification. The magnetic field can be arranged in any suitable manner, for instance the lines of force may be caused to. run

parallel or nearly parallel with the arc which could be readily obtained by surroundin a coil 0 wire carrying a current or the lines of force may be caused'to pass at right i angles to'the arc and;th is latter arrangement appears to give the best result. Such .a. field can readily be created by the use of two or more coils with 'their axes at right anglesto the tube or passage containing the are. or permanent magnets or the like can be employed.

the reaction tube or passage with drawings,

Referring to the accompanying o the'arc K- Figure -1 illustrates a portio;

produced inv the large tube "E; B according.

to the process of Letters Patent No. 930,238 by means of a current of jairfwith a whirling motion around the arc; Fig. 2 shows the same are, but subjected to the modificationaccording -to the. present invention, namely by being subjected to the magnetic field of the pairs of magnetic poles P P, Q Q, R R

and S S. The gases nitrogen and oxygen treated in the are thus subjected to the action of magnetic fields are converted to a'greater -veloping current of gas possessing a whirling motion which consists in subjecting the said arc -'to the action of magnetic fields.

2. The improvement 'in the electric pro- (luction of, endothermic reactions in gases which-consists, in maintaining a cur-rent of the possessing a whirling motion around an electric are which is subjected to the action of a magnetic field.

In testimony that we claim the foregoing as our invention, we have signed our names in presence of two subscribing witnesses.
