Abstract

APPAREIL ET PROCEDE POUR CONTRACTER LA GAINE, POUVANT RETRECIR SOUS L'EFFET DE LA CHALEUR, D'UNE LIGATURE, AUTOUR DE DEUX OBJETS ALLONGES A LIGATURER, PLACES A L'INTERIEUR DE CETTE LIGATURE. L'APPAREIL COMPORTE UN SOCLE RIGIDE POURVU D'UN LOGEMENT PROPRE A RECEVOIR LA LIGATURE, AINSI QUE DES MOYENS PROPRES A RETENIR LESDITS OBJETS ALLONGES DE SORTE QU'ILS CONSERVENT UN POSITIONNEMENT CORRECT DANS LA LIGATURE, ET UN MICROSCOPE MONTE SUR LE SOCLE, PERMETTANT D'OBSERVER LES EXTREMITES DES OBJETS A TRAVERS UNE FENETRE PRATIQUEE DANS LA LIGATURE. UN DISPOSITIF DE CHAUFFAGE DISPOSE SOUS LE SOCLE PERMET DE CREER DE L'AIR CHAUD TRAVERSANT UNE OUVERTURE DU SOCLE DEBOUCHANT DANS LE LOGEMENT, GRACE A QUOI LA LIGATURE PEUT SE RETRECIR AUTOUR DES OBJETS A LIGATURER. PRINCIPALES APPLICATIONS : LIGATURE DE FIBRES OPTIQUES.APPARATUS AND METHOD FOR CONTRACTING THE SHEATH, CAPABLE OF SHRINKING UNDER THE EFFECT OF HEAT, OF A LIGATURE AROUND TWO ELONGATED OBJECTS TO BE LIGATURED, PLACED INSIDE THIS LIGATURE. THE APPARATUS INCLUDES A RIGID BASE PROVIDED WITH A PROPER HOUSING TO RECEIVE THE LIGATURE, AS WELL AS PROPER MEANS TO RETAIN THE SAID ELONGATED OBJECTS SO THAT THEY KEEP CORRECT POSITIONING IN THE LIGATURE, AND A MICROSCOPE MOUNTED ON THE BASE, TO OBSERVE THE ENDS OF OBJECTS THROUGH A WINDOW IN THE LIGATURE. A HEATING DEVICE PROVIDED UNDER THE BASE ALLOWS HOT AIR TO BE CREATED THROUGH AN OPENING IN THE BASE LEADING INTO THE HOUSING, THANKS TO THE LIGATURE MAY TIGHTEN AROUND THE OBJECTS TO BE LIGATED. MAIN APPLICATIONS: LIGATURE OF OPTICAL FIBERS.
