Abstract: To extract and measure out a product from a bulk stock and adding said product inside a hopper use is made of at least three perforated surfaces or plates superimposed on one another and in contact with one another so that the product to be extracted is trapped in the hole(s) in the center plate between the top plate and the bottom plate by a relative movement of the top plate in relation to the two other plates then stationary in relation to each other and the product so trapped in the hole(s) in the center plate is extracted to the outside by a relative movement of the center plate in relation to the top plate and the bottom plate, then stationary in relation to each other, or by a relative movement of the bottom plate in relation to the center plate and the top plate.

Abstract: A hand-held hair-dryer comprises a substantially spherical casing containing an electric heating element associated with an impeller driven by an electric motor. The casing comprises first and second hemispherical caps joined together to form a spherical body with at least one our admission opening between the joined edges of the caps. The impeller is arranged for air to be drawn into the casing through the air admission opening, to then pass into contact with the heating element and finally to pass through the impeller for discharge through a radially directed air-ejection nozzle carried by one of the caps. The dimesions of the spherical casing are such that the hair-dryer can be grasped in the palm of the hand.
