Abstract

The powder reservoir has drilling, in the bottom part which collects part of the power flowing through when open. A horizontal grille (9) is mounted in the lower part of the reservoir, with its edges recessed into the walls so as to allow slight up-and-down movement, and ultrasonic vibration is imparted to it in this direction. There can be a HF generator supplying a transductor (12) inside the hopper, and mechanically coupled to the grille.
