Abstract: A process is described for the preparation of a crosslinkable paint binder by working up a solution of a fluorine-containing copolymer composed of copolymerized units of a perfluoroolefin, a vinyl ester of a short-chain, saponifiable carboxylic acid and a vinyl ester of a strongly branched carboxylic acid which resists saponification. In this process, the bulk of the solvent and the residual monomers are first removed by distillation, the residual highly viscous copolymer is then dissolved in a mixture of alkanol and another solvent which is also capable of dissolving the saponified copolymer to form a homogeneous solution, and the alkaline saponification is subsequently carried out. If desired, the solvent is removed and exchanged for a paint solvent and this solution is finally filtered. A mild saponification is achieved in this manner.

Abstract: To deposit a solderable metal layer on conductive paths (4) of ITO on substrates of display devices (1) by an electroless method, the conductive paths are activated, prior to the deposition, and the areas not covered by the conductive paths are subsequently inactivated. The activated paths are then metallized with a solderable metal layer so that integrated circuits can be soldered to the metallized conductive paths.

Abstract: Oxide cathode wires are produced by coating tungsten wires with emissive material by cataphoretic coating. It is important for the coating to have a substantially uniform thickness over the entire surface of the wire. This is achieved in a simple manner by reversing the polarity of the direction of current flow for a short time at the beginning of the coating process, so that the tungsten wire to be coated is connected as an anode. The remainder of the coating process is performed in a known manner with a tungsten wire connected as a cathode.

Abstract: During silk-screen printing, the stencil (3) is stretched as a result of the pressure exerted by the squeeges (6) This results in a distorted pattern on the material (4) to be printed. To eliminate this error, the design (7') in the stencil (3) is predistorted in such a way that a distortion-free printed pattern (8') is obtained.
