Abstract
Appareil auxiliaire ou similaire avec tôles de noyau en E et en I estampées pratiquement sans chutes, qui sont entourées d'une enveloppe en deux parties, de sorte que chaque tôle de noyau en E et en I est entourée d'une enveloppe, la partie d'enveloppe des tôles de noyau en E chevauchant la partie d'enveloppe des tôles de noyau en I. Dans la zone de leurs joints 5, 6 vis-à-vis des tôles de noyau en I 2, les tôles de noyau en E 1 sont munies de petites découpes, dans lesquelles viennent se placer les extrémites 7, 8 de la partie d'enveloppe 4 entourant les tôles de noyau en I. Applications : aux lampes fluorescentes et autotransformateurs sans starter.
