Abstract
Pour distribuer une quantité déterminée de poudre à partir d'un récipient de fluidisation muni à sa partie inférieure d'une soupape débouchant dans un récipient récepteur, on ouvre et ferme alternativement la soupape pendant de brefs instants en faisant en sorte d'égaliser la pression dans le récipient de fluidisation et dans le récipient récepteur, on pèse le poids du récipient récepteur et de la poudre qu'il renferme entre chaque fermeture et réouverture de la vanne, et interrompt la succession d'ouverture et de fermeture lorsque le poids voulu est atteint.
