Abstract
Appareil d'application de particules magnétiques sur une image magnétique. Appareil comprenant deux cylindres tournant partiellement plongés dans les particules d'agent de virage et portant chacun à sa surface une hélice magnétique. Une lame située entre chacun des cylindres et l'image magnétique latente crée une onde stationnaire fluidisée de particules, qui touche l'image magnétique latente. Application aux appareils de reproduction à image magnétique latente.
