  GENERATEUR ELECTRONIQUE, TRES HAUTE TENSION, SERVANT AU TEXTILAGE SUR
ADHESIF, POUR LA DECORATION D'OBJETS DIVERS. 



  DESCRIPTION. 



   Cet ensemble qui comprend essentiellement un circuit résonnant excité par impulsion fournit les 25.000 volts nécessaires soit à un plateau se trouvant au dessus du redressement, soit relié à une pelle., formant un courant statique entre plateau ou pelle et un objectif négatif. 



   Le plateau est généralement employé pour le textilage en sé- ries sur papiercarton,, tissus et objets de petites dimensions. 



   La pelle est employée pour toutes surfaces verticales. Cet en- semble peut servir également à   la,projection   de poudre de liège., de cuir, de lainede fibrane, d'abrasif, et de poudres métalliques. 



   Le circuit résonnant produit des pointes de tensions d'environ   8.500   volts qui sont appliqués à un circuit redresseur tripleur de tension donnant à la sortie 25.000 volts environ. 



   Les trois diodes et les capacités de filtrage sont'montées dans une boite métallique étanche remplie d'huile. Cette boite avec les deux tubes montés à l'intérieur forment un chassis nécessitant seulement une ali- mentation de 6 volts 3 pour les filaments et'une haute tension de 350 volts. 



   Ces tensions sont obtenues par une alimentation séparée. Elles peuvent également être prises sur l'alimentation alternatif   d'un   poste ré- cepteur de radio. Quand le courant dépasse 200"A. la tension de sortie chute rapidement ce qui constitue aussi un dispositif de sécurité supplémentaire.

  ELECTRONIC GENERATOR, VERY HIGH VOLTAGE, USED FOR TEXTILING ON
ADHESIVE, FOR THE DECORATION OF VARIOUS OBJECTS.



  DESCRIPTION.



   This assembly which essentially comprises a resonant circuit excited by impulse supplies the 25,000 volts necessary either to a plate located above the rectification, or connected to a shovel, forming a static current between the plate or shovel and a negative objective.



   The tray is generally used for batch textilizing on paper, cardboard, fabrics and small items.



   The shovel is used for all vertical surfaces. This assembly can also be used for the projection of cork powder, leather, fiber wool, abrasive, and metal powders.



   The resonant circuit produces voltage spikes of about 8,500 volts which are applied to a voltage tripler rectifier circuit giving the output about 25,000 volts.



   The three diodes and the filtering capacities are mounted in a sealed metal box filled with oil. This box with the two tubes mounted inside forms a frame requiring only a 6 volt 3 power supply for the filaments and a high voltage of 350 volts.



   These voltages are obtained by a separate power supply. They can also be taken from the AC power supply of a radio receiver. When the current exceeds 200 "A, the output voltage drops rapidly which also constitutes an additional safety device.



  Very high voltage power supply. Element values: High frequency oscillating lamp I; High frequency lamp II; 3-4-5 rectifier lamps 8.500 volts plate.
