Abstract

L'invention porte sur un appareil thérapeutique gyromagnétique portatif à aimant permanent comprenant un rouleau magnétique placé dans un boîtier cylindrique (7) constitué de matériau non métallique. Ledit rouleau est entraîné par un moteur (11) pour tourner coaxialement sans balayage. Ledit rouleau magnétique est constitué d'une colonne faite de cinq couches parallèles les unes aux autres le long du sens de son axe. La section transversale de la colonne est circulaire ; la troisième couche médiane (4) ainsi que la première et la cinquième couche (2, 6) situées aux extrémités extérieures de la colonne sont constituées de matériaux ferromagnétiques ; la seconde couche et la quatrième couche (3, 5) situées respectivement entre la première et la troisième couche d'une part, et entre la troisième et la cinquième couche d'autre part, sont constituées de matériaux formant aimant permanent, la direction de magnétisation étant perpendiculaire au plan auquel adhèrent lesdits matériaux, et orientée vers la troisième couche à laquelle ils adhèrent ou à l'opposé de celle-ci. L'appareil utilise deux sources magnétiques et des circuits magnétiques parallèles de manière à raccourcir le circuit magnétique et à collecter le flux magnétique, les composants dudit flux pouvant être équilibrés. L'appareil ici décrit permet de rectifier les défauts présents dans les circuits magnétiques des séries antérieures et peut être utilisé comme appareil thérapeutique gyromagnétique portatif à aimant permanent.
