Abstract

LE DISPOSITIF DE PURGE DE GAZ DE CE FILTRE COMPREND UN FLOTTEUR4 QUI EST SOULEVE PAR LE LIQUIDE ENTRANT PAR LA TUBULURE7 ET QUI EST SUSCEPTIBLE DE FERMER UN EVENT5 AU SOMMET DU BOITIER1. UN VOLUME DE GAZ9 EST MAINTENU EN PERMANENCE AU-DESSUS DU LIQUIDE. LE LIQUIDE EST DEGAZE EN PARTIE PAR SON BRUSQUE CHANGEMENT DE DIRECTION SUR LE BORD SUPERIEUR8 D'UN CYLINDRE6 PLACE AUTOUR DE L'ELEMENT (BOUGIE) FILTRANT10. LES PETITES BULLES RESTANT ENCORE DANS LE LIQUIDE NE PEUVENT PAS TRAVERSER LA COUCHE FILTRANTE ET REMONTENT DANS LE VOLUME DE GAZ9 SOUS FORME DE BULLES PLUS GROSSES. L'INVENTION EST NOTAMMENT APPLICABLE AU FILTRAGE DE LIQUIDE UTILISES POUR L'ENDUCTION DE BANDES ET DE FEUILLES AVEC DES EMULSIONS PHOTOGRAPHIQUES.THE GAS PURGE DEVICE OF THIS FILTER INCLUDES A FLOAT4 WHICH IS LIFTED BY THE LIQUID ENTERING THROUGH TUBING7 AND WHICH IS LIKELY TO CLOSE A VENT5 AT THE TOP OF THE BOX1. A VOLUME OF GAS9 IS PERMANENTLY MAINTAINED ABOVE THE LIQUID. THE LIQUID IS DEGAZED IN PART BY ITS SUCCESSFUL DIRECTION ON THE UPPER EDGE8 OF A CYLINDER6 PLACED AROUND THE FILTERING ELEMENT (SPARK PLUG )10. SMALL BUBBLES STILL REMAINING IN THE LIQUID CANNOT PASS THROUGH THE FILTER LAYER AND RISE UP IN THE VOLUME OF GAS9 AS LARGER BUBBLES. THE INVENTION IS IN PARTICULAR APPLICABLE TO THE FILTERING OF LIQUID USED FOR COATING STRIPS AND SHEETS WITH PHOTOGRAPHIC EMULSIONS.
