Abstract

a. Installation pourvue d'un noyau ferromagnétique fixe et d'une armature de levage mobile. b. Installation caractérisée par des buses éjectant un gaz sous pression, disposées dans les faces correspondantes du noyau fixe et de l'armature mobile, ainsi que dans le guidage de l'armature, l'air des espaces intermédiaires étant comprimé lors d'un déplacement de l'armature dans l'une ou l'autre direction, pour s'échapper lentement à l'extérieur à travers des canaux étroits de section réglable, en amortissant le déplacement. c. Disposition applicable à la commande de déplacement des plaques de semi-conducteurs.
