  • Patent number: 6379446
    Abstract: Compositions and methods in which dry-committed fibers are substantially homogeneously dispersed throughout a fibrous composition. The fibrous composition is characterized as having sufficient yield stress and viscosity such that the shearing forces from the mixing apparatus are effectively transferred down to the fiber level. This is accomplished by means of an appropriate thickening agent, e.g, gelatinized starch. The dry-committed fibers are exemplified by flash dry fibers or fibrous sheets that have been cut or torn into fragments less than 2 cm across. Providing fibers that have been dry-committed greatly reduces the time that it takes to obtain substantially homogeneous dispersion of the fibers throughout the fibrous composition. This, in turn, reduces the risk of mixture spoilage and mechanical or chemical damage to the solid components within the fibrous composition.

    Abstract: Sorghum millet stalks are defibrated and refined into fibers, after which, a cohesive material is admixed with such sorghum millet fibers so as to provide a lump of initially cohered sorghum millet fibers, which is then shaped in the form of a mat. This mat is subjected to a press working process so that a desired shape or uneven shape of panel is produced. During the press working process, the cohesive material is compressed and changed into a state where is acts as a bonding agent to strongly cohere the sorghum millet fibers integrally together. Together with the cohesive material, a bonding material may be admixed with the sorghum millet fibers. Thus, it is possible to obtain a sorghum millet fiber panel which has a strength enough for usual use as with other panels and boards.

  • Patent number: 5763509
    Abstract: To form a binder from naturally occurring products or a fuel brick or pellet using the binder without extraction or purification steps, the binder utilizes proteins from the germ or endosperm of cereal grasses or from the seed of buckwheat, oil seed plants, Amaranthus or leguminous plants or from leaves or from grain stillage. The protein has a thermoplastic microstructure with linear polymers of molecular weight of at least 2,000 linked with peptide linkages of at least 50 in number. The binder is mixed with waste such as municipal waste without further processing and processed in a pelleting machine.

  • Patent number: 5714525
    Abstract: Densified particles of friction ingredients which include an uncured mix of friction ingredients with a thermosetting binder resin and an effective amount of a liquid coreactive with the resin which maintains the temperature during particle formation below the curing temperature of the resin can be used to make friction elements. Methods of forming friction elements from the particles and friction elements made from the particles also are described.

  • Patent number: 5663221
    Abstract: Medium density fiber boards having sufficient physical strength are made from sunflower seed husks by an efficient method. The method of forming the boards involves impregnanting sunflower seed husks with steam, digesting so as to de-fibrate the husks, mixing the de-fibrated sunflower seed husks with a resin, drying the mixture and pressing the dried mixture into a medium density fiber board.

  • Patent number: 5639804
    Abstract: The present invention relates to a friction material comprising a silicone resin, a phenolic resin, and, in certain embodiments, silicon nitride particles, incorporated into an aqueous paper formulation which is then formed into a friction material. The friction material is prepared by mixing the silicone resin, the phenolic resin (and, in certain embodiments, silicon nitride particles) into a raw paper formulation, forming a porous friction material, and heating the friction material to cure the phenolic resin and silicone resin.

  • Patent number: 5506285
    Abstract: To form a binder from naturally occurring products without extraction or purification steps, the binder utilizes proteins from the germ or endosperm of cereal grasses or from the seed of buckwheat, oil seed plants, Amaranthus or leguminous plants or from leaves. The protein has a thermoplastic microstructure with linear polymers of moleculer weight of at least 2,000 linked with peptide linkages of at least 50 in number. The naturally occurring product is ground or milled without further processing and thus includes carbohydrates, particularly as cellulose, and possibly fats, yeast or materials yielding ash upon burning, with the carbohydrates being at least 5 percent of the proteins by weight. The binder may include some initiators or catalysts to polymerize fats or other initiators or catalysts to polymerize proteins.
