Abstract: The invention relates to a method for treating process fluids, such as those which are produced when a process liquid is separated into different process gases using an electric current in an electrolysis cell (10), comprising at least one fluid circuit in which at least one of the process gases is contained in the process liquid, thereby forming the process fluid, wherein at least one fluid storage tank (22) is provided as part of the fluid circuit. The invention is characterized in that the fluid storage tank (22) is equipped with at least one filter device (24), by means of which the process fluid is cleaned of any possible particulate contamination and simultaneously the contained process gas is separated from the process fluid while the process liquid is retained.

Abstract: A linear drive system has an actuator (10), which can be moved in a translatory manner by an electric drive (12) and which is coupled to a mechanical energy storage (16) in the form of a spring (32). In the event of a loss of energy at the electric drive (12) or in an emergency operation, the actuator (10) travels to a predeterminable position and in so doing exerts an actuating force. One free end of the spring (32) is supported at the free end of the spindle housing (20), and the other free end of the spring (32) is supported at a closing part (36) of the actuator (10) or at the actuator (10) itself and is tensioned in every travel position of the actuator (10).

Abstract: A guiding device for strand-shaped components, such as energy- and/or information-conducting cables (5) of wind turbines (1, 3), has a guiding part (7) for partially holding the components. The guiding part (7) can be fastened to a tower segment (3) of the turbine (1, 3) by a fastening apparatus (13, 15). The fastening apparatus performs the fastening of the associated guiding part (7) by an adhesion apparatus (13), preferably in a detachable manner.
