    摘要: The disclosed is a method for producing a carbon material dispersion which removes efficiently and reliably metallic components from carbon materials, and that provides a carbon material dispersion of a high product quality and stable electrical properties. The method comprises a first magnetic separation step in which the powdered and/or granulated carbon material C is applied to the surface of a rotating magnetic roll 130 to remove the metallic component M from the carbon material in the dry state of the powdered and granulated carbon material C; and a second magnetic separation step in which a magnet element 310 is placed in a carbon material dispersion D, in which the carbon material from which the metallic component has been removed in the first magnetic separation step is dispersed in a dispersing medium, in advance of the second magnetic separation step.

    摘要: Easy-Air (-) Ion Generator: The present invention provides an electric device that creates ‘corona discharge’ for cleaning the air from airborne/atmospheric particulate matter including gaseous and biological contaminates. The invention uses high voltage DC current that performs two functions/phases: (1) The first function has two pairs of positive and negative polarity, therein for building a force field between the metal plates for attracting airborne particles, gaseous and biological contaminates that are incinerated. SEE FIG. #1. (2) The second function has negative current wires that goes across the force field, which comes into contact with the filtered air separating negative ions that flow into the room or local area. SEE FIG. #2. The negative ions attach themselves to any particulate matter including soot, tobacco smoke, smog, oil smoke, fly ash, cement dust, suspended atmospheric dust, settling dust, and heavy dust and with its increased molecular weight and pulls the particulate matter to the ground or surface reducing/related atmospheric particulate matter to enhance air quality. Any related airborne/atmospheric particles with a heavier molecular weight due to the negative ionization process are also attracted to the positive current force field and are re-filtered to enhance air quality. SEE FIG. #1. Additionally, the corona discharge is used to split the diatomic oxygen molecule into valent oxygen atoms. These oxygen atoms have a negative charge and will bond quickly with another oxygen molecule to produce ozone. For each split oxygen molecule 2 ozone molecules are produced. SEE FIG. #2.
