PRECIS DE LA DIVULGATION
L'invention a pour but de réduire la puissance consom-
mée globale par une boucle induisant un courant alternatif
à haute fréquence dans les rails d'une voie ferrée pour la
transmission d'informations aux trains circulant sur cette
voie. Selon l'invention la boucle est constituée de deux
spires conductrices réalisées au moyen d'une bande conduc-
trice fixée sur une bande isolante, la bande conductrice
étant disposée, dans les parties de la boucle qui sont pa-
rallèles au rail, dans un plan parallèle aux flancs de
l'âme du rail et de part et d'autre de celle-ci, la bande
isolante séparant l'âme du rail et la bande conductrice.
Les deux spires sont connectées de telle manière qu'elles
soient parcourues par un même courant de même sens. Appli-
cation au domaine ferroviaire.
