Abstract
L'INVENTION CONCERNE LES CIRCUITS DE DETECTION DE LA DISTANCE MINIMALE SEPARANT DEUX ORGANES CONTENANT DU FER ET MOBILES L'UN PAR RAPPORT A L'AUTRE. ELLE SE RAPPORTE A UN APPAREIL DANS LEQUEL UN AIMANT PERMANENT 44 ET UNE BOBINE DETECTRICE 52 SONT PLACES DANS UNE BARRE 36 DE CISAILLEMENT EN FACE DE LAQUELLE PASSE UN COUTEAU 34. LE RECOUPEMENT DU CHAMP MAGNETIQUE PAR LE COUTEAU 34 CREE UN SIGNAL QUI EST TRAITE PAR UN CIRCUIT D'INTEGRATION ET QUI PERMET L'INDICATION DE LA DISTANCE MINIMALE SEPARANT LE COUTEAU 34 DE LA BARRE 36. APPLICATION AUX MACHINES A RAMASSER LE FOURRAGE.
