Abstract

a. L'invention concerne la fabrication de buses de projection par galvanoplastie où l'on établit d'abord un modèle négatif sur lequel on dépose la pièce positive. b. Le corps base est fait de plusieurs parties dont les pièces sont dirigées l'une vers l'autre de façon que la pointe de l'une est centrée et maintenue dans un evidement coaxial à l'axe de symétrie de rotation soit de la pointe, soit de la surface de base. c. Ce procédé facilite grandement l'usinage des buses de projection du fait que l'on produit d'abord un négatif des parties intérieures très difficiles à usiner.
