    Abstract: The invention relates to a device for the electrolytic coating of at least one electrically conductive substrate or a structured or full-surface electrically conductive surface on a nonconductive substrate, which comprises at least one bath, one anode and one cathode, the bath containing an electrolyte solution containing at least one metal salt, from which metal ions are deposited on electrically conductive surfaces of the substrate to form a metal layer while the cathode is brought in contact with the substrate's surface to be coated and the substrate is transported through the bath, wherein the cathode comprises at least two disks (2, 4, 10) mounted on a respective shaft (1, 5, 14) so that they can rotate, the disks (2, 4, 10) engaging in one another. The invention furthermore relates to a method for the electrolytic coating of at least one substrate, which is carried out in a device according to the invention. Lastly, the invention also relates to a use of the device according to the invention for the electrolytic coating of electrically conductive structures on an electrically nonconductive support.

    Abstract: Procedimiento para la obtención en continuo de nitritos de alquilo o de dinitritos de alquilo mediante la reacción de un alcanol o de un dialcanol con un nitrito inorgánico en presencia de, al menos, un ácido mineral que no tenga acción oxidante sobre el nitrito, caracterizado porque (i) se mezcla el alcanol o el dialcanol con una solución acuosa del ácido mineral, empleándose, en promedio, una cantidad no mayor que 1,01 moles de equivalentes de ácido por cada mol de grupos hidroxilo del alcanol o del dialcanol, (ii) se aporta en continuo, en una zona de reacción, a la mezcla acuosa, obtenida en (i), una solución acuosa del nitrito inorgánico, y (iii) en caso dado se aísla la fase orgánica.

    Abstract: The invention relates to a method for producing electrically conductive surfaces on a nonconductive substrate, comprising the following steps: a) transferring a dispersion containing electrolessly and/or electrolytically coatable particles from a support onto the substrate by irradiating the support with a laser, b) at least partially drying and/or curing the dispersion transferred onto the substrate, so as to form a base layer, c) electrolessly and/or electrolytically coating the base layer.

    Abstract: The invention relates to a device for the electrolytic coating of a structured or full-surface base layer (9) on a surface of a substrate (7), which comprises at least one electrolyte bath (3) having at least one rotatably mounted roller (2) connectable as a cathode, which contacts the base layer (9) during the electrolytic coating, the base layer (9) being covered by an electrolyte solution (5) contained in the electrolyte bath (3) and being moved relative to the at least one roller (2) during the coating. The at least one roller (2) connectable as a cathode is connected cathodically during the contact with the base layer (9) and is connected neutrally or anodically as soon as there is no contact with the base layer (9). The invention furthermore relates to a method for the electrolytic coating of a structured or full-surface base layer (9) on a surface of a substrate (7), the base layer (9) being surrounded by an electrolyte solution (5) and being contacted by at least one roller (2) connectable as a cathode. The roller (2) connectable as a cathode is connected cathodically when it contacts the base layer (9) and is connected neutrally or anodically as soon as there is no contact with the base layer (9).
