  • Patent number: 12203223
    Abstract: The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.

  • Publication number: 20050028351
    Abstract: A method of making composite electric machine components. Magnetic segments and non-magnetic segments are separately formed to green strength, and then arranged adjacent to each other in a desired magnetic pattern. A small amount of powder material is added in-between the segments, and the whole assembly is then sintered to form a sinterbonded composite component of high structural integrity.
