Abstract: The invention relates to a gas supply for an electrostatic filter and an electrostatic filter arrangement which has an electrostatic filter and a gas supply. Here, the gas supply has an incoming flow channel of constant cross-sectional area, a gas inlet hood with cross-sectional area expanding in the direction of the electrostatic filter, and an admixture arrangement for a conditioning means, wherein at least one flow distributor is arranged in the expanded cross-sectional region of the gas inlet hood. Characterizing features include a first vortex arrangement generating a leading-edge vortex arranged in the incoming flow channel, a second vortex arrangement generating a leading-edge vortex arranged in the gas inlet hood before the flow divider in the gas flow direction, and the admixture arrangement arranged in the region of one of the two vortex arrangements.

Abstract: A mixer for mixing at least two flows of gas or other Newtonian liquids is provided herein. The mixer includes a main flow channel through which a first flow of gas passes, with an incorporated surface that is arranged therein and which affects the flow. This incorporated surface has leading edges that are orientated against the flow and about which the flow can move freely; the leading edges include a component that acts in the direction of the main flow of the gas flow as well as a component that acts transversely thereto. In order to ensure that an additional gas or liquid component is mixed in rapidly, provision is made such that the incorporated structure surface has a chamber into which a separate flow channel for a second gas flow leads and the chamber has outlet openings into the first gas flow on a rear side of the incorporated surface that faces away from the first gas flow.

Abstract: A device for moving transverse beams and workpieces suspended therefrom along a support rail in the longitudinal direction of the support rail. Each one of the transverse beams is connected by lifting devices, for lowering and lifting the workpieces connected to the transverse beam into and out of the zinc bath, to transport carriages riding on the support rail. The transverse beams have a vertically movable doctor blade arrangement at the leading end for removing contaminants from the surface of the zinc bath.
