Abstract: The inventive device for distilling a medium comprises at least one reservoir (11, 51) or accommodating the medium (15, 55) to be distilled, a heating element (12, 52) for vaporizing the medium (55), and comprises at least one collecting vessel (20, 60), which is situated downstream and which is provided with a cooling element for condensing the produced distillation vapor. In addition, a pipe (19, 59) or the like is provided on the top side of the reservoir (11, 51). Said pipe leads into the collecting vessel (20, 60) and connects the vapor space (14, 54) located inside the reservoir (51) to that which is located inside the collecting vessel (20, 60). To this end, means are provided, which, for the most part, completely remove foreign gases from the vapor spaces (14, 24; 54, 64) before or at the beginning of the distillation process.

Abstract: A mixing head to be mounted on a utilization system is operable to mix media and to then supply the mixed media to the utilization system. The mixing head includes a housing having an inlet end and an outlet end. The outlet end has an annular flange to enable the housing to be mounted on the utilization system. A rotor is mounted within the housing for rotation about an axis. The rotor includes an upstream axial flow impeller and a downstream radial flow impeller. Each impeller includes plural rigid and fixed blades. At the outlet end of the housing is an outlet in the form of an annular gap to supply mixed media from the housing into the utilization system. A deflection hood is mounted at the outlet end of the housing. The annular gap is positioned radially outwardly of the hood. The hood has an outer surface that is directed away from the housing and that has a convex shape.
