Abstract: A mechanically roughened substrate is conveyed through an electrolytic bath and is given a superposed electrochemical roughening, which is carried out by means of electrodes which are arranged in the electrolytic bath at a specific spacing from the substrate. The electrodes are connected to corresponding windings on the secondary side of a three-phase transformer. The corresponding windings on the primary side of the three-phase transformer are connected to a three-phase frequency converter, to which three-phase current is applied via leads. The three-phase frequency converter transforms the line frequency of the three-phase current supplied into a frequency range of about 50 to 300 Hz at a voltage of between about 1 and 380 V.

Abstract: An apparatus for drying a liquid layer deposited on a carrier material which is moved through a drying zone, which liquid layer contains evaporable solvent components and non-evaporable components, comprises a drying apparatus (1) with a drying channel (2), through which the carrier material band (4) runs in the longitudinal direction, on which band the liquid layer to be dried is deposited. The drying channel has a gas/air permeable channel covering surface (7), through which a gas flow, in particular a heated air flow, flows into the drying channel. The channel covering surface (7) is inclined in relation to the channel bottom surface (3) which runs horizontally. The drying channel (2) is adjoined by a gas exchange chamber (15) which contains a fan (12), the fan outlet (16) of which is directed towards a heat exchanger in a partition wall (10) between the gas exchange chamber (15) and a drying chamber (5) situated above the drying channel (2). The gas exchange chamber (15) contains a choke device (13 and 14 respectively) in its bottom surface (18) and in its upper gas inlet (19) respectively. The drying apparatus (1) further contains an exhausting fan (9) which is arranged above the covering surface of a through-channel (20) and is connected to the through-channel via a suction opening. In the outlet (11) of the exhausting fan (9) there is also a choke device (8). … …

Abstract: In its lateral surface, a distributor tube 1 has tube slits 10 which are transverse to the direction in which a fluid flows into the distributor tube. A casing tube 7 is enclosed by the distributor tube 1 and is subdivided into flow chambers 4, each of which is bounded by two annular plates 11 and is connected to an inlet sector 14. Situated at the inlet end of the distributor tube is a star-shaped volumetric flow distributor 2 in the form of a tube insert which subdivides the mass flow fed in into subflows for the flow chambers. … …
