PRECIS DE LA DIVULGATION :
Procédé et appareil permettant le pompage d'une masse vis-
queuse épaisse, séjournant à l'air libre, après l'avoir rendue fluide ou
suffisamment liquide pour être pompée.
L'appareil selon l'invention, constitué de manière connue
en soi par une barge ou traîneau, adaptée pour flotter ou glisser à la
surface de la masse visqueuse épaisse, est remarquable du fait qu'il
comporte, d'une part, suspendue en dessous du châssis (2) de support de
pompe, une cage (5) maillée ou grillagée pénétrant dans la masse (M) à
faible profondeur pour délimiter une couche superficielle de cette masse
et, d'autre part, un lit (7) de résistances chauffantes place à faible
distance du fond de cette cage, de façon à être situé dans cette couche
afin de la réchauffer suffisamment pour qu'elle se fluidifie et permette
son pompage.
