Abstract
L'INVENTION CONCERNE LE CLASSEMENT INSTANTANE DES MATIERES PARTICULAIRES. ON FAIT TOMBER LES GRAINS 14 D'UNE CERTAINE HAUTEUR ENTRE UN CONVOYEUR 3 ET UNE TREMIE 4. ON ENREGISTRE STATIQUEMENT, AU MOYEN D'UNE CAMERA DE TELEVISION 7, LA CHUTE DES GRAINS SUR LE FOND D'UN ECRAN 15 ECLAIRE STROBOSCOPIQUEMENT. ON CALCULE, AU MOYEN D'UN ENSEMBLE CALCULATEUR 8, 10, LA SURFACE, LE DIAMETRE, LE POIDS ET LE NOMBRE DE GRAINS, POUR EN DEDUIRE LA REPARTITION, A PARTIR DE L'IMAGE STATIQUE DES GRAINS QUI TOMBENT. APPLICATION AUX MESURES GRANULOMETRIQUES DES MINERAIS, DES CEREALES.THE INVENTION CONCERNS INSTANT CLASSIFICATION OF PARTICULAR MATERIALS. GRAINS 14 ARE FALLED FROM A CERTAIN HEIGHT BETWEEN A CONVEYOR 3 AND A HOPPER 4. STATICALLY RECORDED, BY MEANS OF A TELEVISION CAMERA 7, THE DROP OF GRAINS ON THE BACKGROUND OF A STROBOSCOPICALLY LIGHT SCREEN 15. WE CALCULATE, BY MEANS OF A COMPUTER ASSEMBLY 8, 10, THE SURFACE, DIAMETER, WEIGHT AND NUMBER OF GRAINS, TO DEDUCT THE DISTRIBUTION, FROM THE STATIC IMAGE OF THE FALLING GRAINS. APPLICATION TO GRANULOMETRIC MEASUREMENTS OF MINERALS, CEREALS.
