Abstract

Dispositif pour échanger des creusets dans un appareil de chauffage à l'incandescence pour laboratoire, cet appareil pouvant être fermé de façon étanche et comportant un tube de chauffage entouré par un dispositif de chauffage sur une partie de sa longueur. On dispose, à peu près horizontalement, un cylindre 25 ouvert aux extrémités et pouvant être raccordé de façon étanche à l'appareil de chauffage à l'incandescence 5 et on monte dans ce cylindre 25 un piston 27 que l'on peut faire glisser et qui peut recevoir plusieurs creusets 29 dans des compartiments 28 à partir desquels les creusets peuvent être amenés au dispositif de chauffage 5 par une tige 33. Ce dispositif peut, par exemple, servir à déterminer la teneur en carbone du sodium utilisé comme réfrigérant dans les centrales nucléaires.Device for exchanging crucibles in a laboratory incandescent heater, this apparatus being able to be closed in a sealed manner and comprising a heating tube surrounded by a heating device over part of its length. A cylinder 25 open at the ends and sealingly connectable to the incandescent heater 5 is arranged approximately horizontally, and a piston 27 is mounted in this cylinder 25 which can be slid and which can receive several crucibles 29 in compartments 28 from which the crucibles can be brought to the heater 5 by a rod 33. This device can, for example, be used to determine the carbon content of the sodium used as refrigerant in power plants nuclear.
