Definitions

  • Our invention relates to vapor electric devices such as the mercury rectifier and has for its principal object the provision of an improved apparatus and method of operation whereby the current of a continuously excited vapor electric device may be readily controlled.
  • the current transmitted between the cathode and anode of a continuously excited vapor electric device is controlled by a sleeve or electrode mounted on the outside of the evacuated vessel which encloses the cathode and anode.
  • the rectifier have at least one electrode which is the seat of a continuous emission of electrons, for example, a mercury bath with a sustained cathodic spot or an electrical filament. It is characterized by the fact that there are arranged around the bulb one or more conductor sleeves which are connected with one or more control circuits by means of which these sleeves may be carried to potentials different from those of the electrodes.
  • such an apparatus is provided with one or more conductive sleeves and if these sleeves are carried to a' suitable potential, the electromagnetic field thus created in the rectifier will prevent formation of the are. It is hence possible, by means of such sleeves to prevent passage of the current or to permit it to pass as desired; also, by carrying these sleeves periodically, more or less rapidly and more or less regularly, to the suitable potential, it is possible to permit the passage of the continuous pulsating current fed only perlodlcally for longer or shorter periods of time, that 1s, to regulateas desired the mean or average intensity of the current; by periodically increasing or decreasing the otential of the sleeve we thus obtain an un ulatory current and of any desired frequency lower than that of the feed current.
  • the arrangement thus permits of obtaining elther an interrupter or a relay, by means of which the changes of periodicity of the potential variation of the sleeve will be reproduced by the variations of the intensity of the feed current.
  • the present invention is clearly difl'erent from any of the preceding devices.
  • Fig. 1 shows an arc rectifier truth 'a single anode the cathode of which is in a mercury bath having a sustained cathodic spot.
  • Fig. 2 shows an arc rectifier with a single anode and the cathode of which is formed y an electrically heated filament.
  • Fig. 3 is an arc rectifier with two anodes with a cathodic spot fed by a transformer.
  • the bulb 1 contains a main cathode 2 and an auxiliary cathode 3, and at the other end an anode 4.
  • This bulb 1 is" fed by an alternating current source the terminals of which are indicated at 11. 12
  • a sleeve 5 connected to an electric source, for example, a battery or series of batteries by means of a movable commutator 7 which permits of carrying it to a more or less high potential.
  • the main cathode 2 and the auxiliary cathode 3 are placed in a continuous current circuit 13-14.
  • An auxiliary are 9 remains continually ignited by the passage of the continuous current circuit 13-14 between the cathodes 2 and 3.
  • the main arc 8 is formed between the cathode 2 and the anode 4 at each positive half period of the alternating current coming from the terminals 11.
  • the formation of the arc permits the passage of a continuous pulsatingcurrent which is utilized in the circuit 12. If we carry the sleeve 5 to a negative potential with respect to the cathode 2, the main are 8 will not be formed between the cathode 2 and the anode 4 at each half period in which it would be formed if this sleeve 5 were not carried to this potential.
  • the sleeve 5 may serve to interru t the supply of current of the rectifier and t 115 by means of a current which is extremely slight relative to-the current fed by the arc. If it is desired to establish an interrupter directly on the load circuit, it is necessary to give it dimensions and strength relative-to the voltage and intensity of the current used.
  • the elements are the same as in that of Fig. 1, except as follows.
  • the cathode is formed of a filament 10 heated by a source of continuous current 15.
  • the operation is exactly the same as that of the device of Fig. 1.
  • the rectifier comprises a main cathode 18 and an auxiliary cathode 19 placed in the continuous current circuit and producing a permanent are for the maintenance of the cathodic spot of bath 18.
  • the rectifier comprises two anodes 16 and 17 which are connected respectively tothe ends of two windings of a transformer 22-23.
  • the useful circuit is passed to terminals 25-26 connected respectively with the cathode 18 and with the neutral point 24 of the transformer 22-23.
  • Sleeves 20-21 are arranged on each arm of the rectifier near the anodes 16-17.
  • These sleeves are connected respectivel to the ends 22-23 of the transformer win ings by acommutator 27 which permits of connecting each sleeve 20-21 with the end 22-23 which feeds the corresponding anode 16-17, or reversing this connection.
  • each sleeve 20-21 be connected to the same end 22-23 of the transformer as the corresponding anode 16-17
  • the sleeve will. have at each instant the same potential as the anode and its presence will not prevent the formation of one or the other of the arcs which play between the cathode 18 and the anode 16 or 17; on the contrary, the formation of this are will be facilitated.
  • each sleeve 20-21 will have a negative potential while the correspondin anode 16-17 will have a positive potentia that is, at the moment at which the arcs 18-16, 18-17 may be formed, and will prestated, a series 0 pulsations which are more or less long and more or less s aced apart.”
  • each bulb in operation, will permit the passage of one of the. phases, and the whole will feed alternating current.
  • the sleeves By the operation or movement of the sleeves it is thus possible to effect interruption or regulation of the alternating current fed, as previously herein. described.
  • the invention will permit of being employed in most cases where three electrode lamps are used, for example, in rectifying currents, amplification, generation of high or low frequency alternating current and in frequency transformation.
  • a continuously excited arc device provided with an anode and a cathode enclosed 5 within an evacuated vessel and with a control electrode mounted outside; of said vessel and arranged to prevent the starting of the arc of said device.
