Definitions

  • the principal object of the invention is to obtain the maximum yield of oxides of nitrogen in the electric fixation of atmospheric nitrogen and to accomplish-the de- 5 sired result in a simple and inexpensive manner.
  • the principal feature of the invention consists in the novel method of transformin a portion of the current flowing to the elec- 10 trodes of an oxidizing apparatus and; effecting a substantial increase in the frequency thereof to more nearly harmonize with the natural frequency of the atoms of oxygen and nitrogen.
  • the drawing is a diagrammatic illustration of my method.
  • the present invention purposes the application of new conditions to the electric.
  • the electrodes constitute a stationary annular electrode A and a rotatable central electrode B, between which is formed an annulus of electric flame which is blown into a tubular form by the flow of air therebetween.
  • the electric leads 1 and 2 of the electrodes A and B respectively are tapped by.
  • the wires 3 and 4 and these wires are connected in the manner shown, to the primary and secondary coils 5 and 6 respectively. of the transformer which steps up the current from a normal commercial voltage, such as one thousand volts, voltage, say six thousand volts, and say at sixty cycles. 7
  • the wire 4 is connected to one end of the primary 5 and wire 3 is connected to the other end.
  • the secondary 6 is connected to the wire 3 and back to the wire 4 through the wire 7 and condenser 8.
  • the frequency of the secondary circuit is multiplied by the introduction of an interrupter 9 which is placed in a shunt 10 between the wires 3 and 7 and the result of the operation of this interrupter, which is rotated at high speed, say approximately to a higher.
  • What I claim as my invention is 1. A method of electric formation of oxides of nitrogen..consisting in producing an electr1c arc with a commercial frequency current by the introduction of the high fre-v quency current into the circuit and directing a flow of air through the zone of the arc. 2. method of electric formation of ox- 1des of nitrogen. consisting in utilizing a commercial frequency current connected to the electrodes of an are producing device by tapping the main line circuit to the electrodes for producing the oxidizing arc and creating a high frequency current in the tapped-circuit and directing a flow of air through the zone of the arc.
  • a method of electric formation of oxides of nitrogen consisting in utilizing a commercial frequency current by tapping the leads to the electrodes of an. oxidizing apparatus connected with said commercial frequency circuit and introducing a transformer in the subsidiary circuit and arranging a high frequency interrupter in a shunt in the secondary winding of the transformer connecting the high frequency current to the main circuit and directing a flow of air past the electrodes.
  • Means for the electric formation of oxides of nitrogen comprising the combination with circular electrodes, of a pair of taps leading from the main current supply leads, a transformer having its primary connected with said taps, and its secondary connected to one of said taps and returned
