Abstract: The invention relates to a flexible flat electrode arrangement for a dielectrically limited gas discharge, comprising a central region (3), an edge region, and a flat electrode (14) which conducts a high-voltage potential and which is embedded in a flat dielectric that forms an upper face (10) and a contact face (6). The invention allows the active surface of the electrode arrangement to be matched to the size of a surface to be treated in that the flat dielectric is in the form of a flat strip (1) wound into a spiral at least in the edge region, and the electrode (14) is formed by at least one electric conductor which runs in the longitudinal direction of the wound strip (1) and which leads into an end surface (13) of the strip (1).

Abstract: In order to treat human or animal hair fixedly arranged on a sopport, hair is divided into strands. The divided strands are subjected to a dielectric plasma treatment by drawing an apparatus connected to a high voltage source (8) through the strands. The apparatus can be in the form of tongs or have a comb-like structure.

Abstract: A valve arrangement for vibration decoupling has a housing, in which two valve bodies are accommodated, a first of which is biased by a spring in a reference direction towards a stop integral with the housing and has a through-path for fluid. The other housing is biased by a spring in an opposite direction towards a valve seat on the first valve body and lifts away from the latter in the event of a volume flow in the reference direction, so as to open the through-path for fluid. A further through-path for fluid is provided between the first valve body and the housing, wherein a further valve seat is formed on the stop integral with the housing, towards which further valve seat the first valve body is biased by a spring and lifts away from the valve seat in the event of a volume flow in the opposite direction.
