    Abstract: Apparatus in plants, particularly for use in making master phonograph records and the like.In plants (FIG. 1) for galvanic processing in making master phonograph records, the apparatus in accordance with the invention comprises an arrangement of the receptacle (12) containing anode material (16) such that the electrolyte (2) is constrained (19, 35) to a given extent to flow through the receptacle in a direction from the surrounding liquid in a processing tub (1). The receptacle (12) is connected to an outlet (35) for liquid such that there is always a level (37) of liquid in the receptacle lower than the level thereof in the tub. By means of the liquid flow there is gained that particles which may be liberated from the anode material are not carried over to the object on which electro deposition takes place.
