John H. Klungness has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11015295
    Abstract: A method of making paper is described. The method includes providing a cellulosic fibrous material, the cellulosic fibrous material comprising a plurality of elongated fibers having a fiber wall surrounding a hollow interior, the fibrous material having moisture content. The method also includes adding calcium bicarbonate solution to the cellulosic fibrous material to form a pulp mixture, the calcium bicarbonate solution containing up to the saturation level of about 16% solids of calcium bicarbonate, the resulting pulp mixture having between 0.1% to 65% total solids by weight. Further, the method includes refining the pulp mixture such that at least some of the calcium ions become associated with the reactive sites in the fiber walls. Further still, the method includes forming a web from the pulp mixture and wet pressing the web.

  • Patent number: 5223090
    Abstract: The present invention relates to a method for loading a chemical compound within the fibers of a fibrous material and to the fibrous materials produced by the method. In the method, a fibrous cellulose material is provided which consists of a plurality of elongated fibers having a fiber wall surrounding a hollow interior. The fibrous material has a moisture content such that the level of water ranges from 40-95% of the weight of the fibrous material and the water is positioned substantially within the hollow interior of the fibers and within the fiber walls of the fibers. A chemical is added to the fibrous material in a manner such that the chemical is disposed in the water present in the fibrous material. The fibrous material is then contacted with a gas which is reactive with the chemical to form a water insoluble chemical compound. The method provides a fibrous material having a chemical compound loaded within the hollow interiors and within the fiber walls of the plurality of fibers.
