Patent

CA 2631366

The present invention provides a method of drawing a thermoelectrically active material (22) in a glass cladding (14), comprising sealing off one end of a glass tube (14) such that the tube (14) has an open end and a closed end, introducing the thermoelectrically active material (22) inside the glass tube (14) and evacuating the tube (14) by attaching the open end to a vacuum pump, heating a portion of the glass tube (14) such that the glass partially melts and collapses under the vacuum such that the partially melted glass tube (14) provides an ampoule (54) containing the thermoelectric material (22) to be used in a first drawing operation, introducing the ampoule (54) containing the thermoelectric material (22) into a heating device (10), increasing the temperature within the heating device (10) such that the glass tube (14) melts just enough for it to be drawn and drawing fibers (24) of the glass clad thermoelectrically active material (22).

La présente invention concerne un procédé d~étirement d~un matériau thermoélectriquement actif (22) dans un revêtement de verre (14), consistant à sceller une extrémité d~un tube de verre (14) de sorte que le tube (14) comprenne une extrémité ouverte et une extrémité fermée, à introduire le matériau thermoélectriquement actif (22) dans le tube de verre (14) et à évacuer le tube (14) en connectant l~extrémité ouverte à une pompe à vide, à chauffer une partie du tube de verre (14) de sorte que le verre fonde partiellement et s'affaisse sous l~action du vide de sorte que le tube de verre (14) partiellement fondu crée une ampoule (54) contenant le matériau thermoélectrique (22) à utiliser dans une première opération d~étirement, à introduire l~ampoule (54) contenant le matériau thermoélectrique (22) dans un dispositif de chauffage (10), à augmenter la température dans le dispositif de chauffage (10) de sorte que le tube de verre (14) fonde juste assez pour qu'il soit étiré et à étirer des fibres (24) du matériau thermoélectriquement actif (22) recouvert de verre.
