Abstract

LA PRESENTE INVENTION CONCERNE UN APPAREIL DE COMPTAGE DE PARTICULES EN SUSPENSION DANS UN MILIEU LIQUIDE. UNE CHAMBRE W RECOIT UN ECHANTILLON DU MILIEU LIQUIDE CONTENANT DES PARTICULES ET CET ECHANTILLON SORT DE LA CHAMBRE PAR UNE CONDUITE 5. CETTE CONDUITE EST NORMALEMENT FERMEE SAUF POUR LAISSER PASSER DES PARTICULES. UN COMPTEUR COMPTE LES PARTICULES DANS L'ECHANTILLON TANDIS QUE CELUI-CI CIRCULE DANS LA CONDUITE ENTRE DES ELECTRODES E1 ET E2. L'APPUI SUR UNE TOUCHE K ECARTE LE FOND B DE LA CHAMBRE W DE L'EXTREMITE DE LA CONDUITE ET LAISSE PASSER L'ECHANTILLON TOUT EN VALIDANT LES DIVERS CIRCUITS DE COMPTAGE 13. APPLICATION A LA REALISATION D'UN APPAREIL DE NUMERATION GLOBULAIRE PORTATIF.
