摘要： Plant for producing electric power from a watercourse is comprised of immersed turbines. The turbines known of this type are anchored in the bed of the river by complex and expensive arrangements. Such arrangements are superfluous if the turbine assembly (1) comprised of one or a plurality of turbines immersed and forming a closed unit is anchored while floating freely on the water. Cables (2) are anchored to pillars (3), buoys, rafts or pontoons. It is also possible to anchor the turbine assembly directly to the raft (9) or pontoon. To increase the floating capacity, the turbine assembly is provided with floating chambers.

摘要： Dispositif electronique pour l'excitation d'un element electromagnetique, notamment une bobine d'arret ou une bobine d'un appareil de commutation electromagnetique presentant un circuit magnetique avec bobine, culasse et armature. Un comparateur (5) recoit une valeur de consigne de courant predetermine U(Isoll2) et une valeur reelle de courant mesuree U(Iist). Lorsque la valeur reelle descend en dessous de la valeur de consigne, le comparateur (5) active, a travers un element a bascule monostable (6), un transistor de commutation (1) alimente par une tension d'alimentation Uv, situe dans le circuit de courant principal de l'element electromagnetique (2). Apres ecoulement de la duree de conduction tein constante, il bloque le transistor (1). Avec une duree de conduction tein variable du transistor de commutation (1), il en resulte une variation de la valeur de consigne de courant, fonction de la duree de conduction determinee. Afin d'obtenir un mode de fonctionnement sur d'un appareil de commutation electromagnetique comportant une bobine, on etablit une valeur de consigne de courant d'actionnement eleve et, apres l'obtention de l'actionnement de l'appareil de commutation, une valeur de consigne de courant de maintien reduite. Pour l'exploitation des differents etats de commutation de l'appareil de commutation, on tient compte de l'inductivite de la bobine.

摘要： A high-voltage composite insulator is substantially comprised of a rod (2) of synthetic material reinforced with fiber glass, screen forming bodies (3) and connection armatures (4). The outer cylindrical surfaces of the rod (2) of synthetic material reinforced with fiber glass are coded with a first layer (5) of silicon rubber and with a second layer (6) of synthetic plastic grease. The screen forming bodies (3) are crimped on said outer layer of the rod (2) of synthetic material. These screen forming bodies are made of polytetrafluoroethylen. They present in the direction of the longitudinal axis thereof smooth cylindrical bores (7). The diameter of these bores (7) is very slightly smaller than the diameter of the rod (2) covered by said layers. The screen forming bodies (3) supported by the synthetic material rod (2) are heated before their mounting and then set on the rod (2). In order to prevent water or dirt from penetrating inside the screen forming bodies (3) threaded onto the synthetic material rod (2), these bodies are preferably assembled by a tongue and groove joint (9a and 9b).
