Abstract: A method of manufacturing a highly electrically conductive plastic material from thermoplastic resin and carbon fill through a two-screw mixer having a screw length of more than twenty times the screw diameter involves continuously inserting a thermoplastic resin into a first zone of the two-screw mixer and compacting and preheating the thermoplastic resin. The resin is then passed into a second zone where it is kneaded and plastified. A particulate carbon fill is continuously inserted into a third zone with the fill constituting 30 to 50% by weight of the mixture and being dispersed in said resin within the third zone. The speed of rotation of the two screw mixer lies in the range between 150 to 250 RPM and the temperatures of the zones lie within the range of 165.degree. C. to 300.degree. C. After passage through the various zones, the mixture is removed via an outlet of an extrusion head.

Abstract: The invention relates to a conductive plastic material based on a thermoplastic resin and a carbon fill including both particles and fibers. The particles fill constitutes 30% to 50% by weight of the material, and the fiber fill constitutes not more than 10% by weight.

Abstract: The component plates stacked in a filter press type structure in a repeated cathode, separator, anode and conductive plate sequence are of hexagonal or duodecagonal shape with an outer frame carrying the channels for supplying and withdrawing the reagents. Hollowed-out inlet and outlet portions communicating with appropriate channels passing through the frames are provided for passing the reagents across the active portions of the components at a desired cross-feed angle between adjacent units, 30.degree. in some cases and 60.degree. in others.

Abstract: The component plates stacked in a filter press type structure in a repeated sequence of cathode, separator, anode and conductive plate are of cylindrical shape with an outer frame carrying the channels for supplying and withdrawing the reagents. Hollowed-out inlet and outlet portions communicating with appropriate channels pressing through the frames are provided for passing the reagents across the active portions of the components at a desired cross-feed angle between adjacent units, 30.degree. in one case and 60.degree. in another.
