Abstract
LA PRESENTE INVENTION CONCERNE UN PROCEDE ET UN APPAREIL DE MESURE DES DIMENSIONS DE FIBRES DE BOIS. CE PROCEDE CONSISTE A DILUER DES FIBRES DE BOIS DANS UN VEHICULE PORTEUR, PAR EXEMPLE DANS UN BAC 15, A FAIRE CIRCULER LE LIQUIDE PORTEUR AU MOYEN D'UNE POMPE 11 DANS UNE CANALISATION 10 COMPRENANT UNE CHAMBRE 12 DANS LAQUELLE EXISTE UN ECOULEMENT TURBULENT, ET A CAPTER UNE PARTIE DU LIQUIDE COMPRIS DANS LA CHAMBRE 12 VERS UNE DERIVATION 13. UN TUBE TRANSPARENT EST PREVU SUR UNE PARTIE DE LA DERIVATION 13 ET LA LONGUEUR DES FIBRES PASSANT DANS LA DERIVATION EST MESUREE OPTO-ELECTRONIQUEMENT ALORS QUE LES FIBRES SONT EN CIRCULATION. APPLICATION A LA FABRICATION DE LA PATE A PAPIER.
