  • Patent number: 4818530
    Abstract: This invention relates to a method for preparing pellets containing living biocontrol fungi. Fungi are selected and grown for sufficient time to produce inoculum. The fungal propagules are harvested, homogenized and diluted with sodium alginate solution. Pelletization is then accomplished by dropwise addition of the fungal propagule-alginate mixture into a solution of calcium chloride or calcium gluconate. The resultant alginate gel pellets containing living fungi can then be dried and are used to inoculate agricultural fields infested with soilborne plant diseases.

  • Patent number: 4818243
    Abstract: Acetals of glyceraldehyde, when applied to cotton fabric by conventional pad-dry-cure procedures using special combined acid catalysts, were found to crosslink the cellulose hydroxyl groups at a very rapid rate (e.g., 10 seconds at 170.degree. C.), thereby imparting improved wrinkle recovery. In particular, the aldehydes studied were the diethyl and dimethyl acetals of glyceraldehyde. The best results were obtained with glyceraldehyde dimethyl acetal.

  • Patent number: 4806475
    Abstract: Nonwoody lignocellulosic portions of plant fruits, roots, and tubers, such as sugar beet pulp, citrus pulp, seed hulls, and cereal bran are treated with hydrogen peroxide under alkaline conditions thereby delignifying the materials and rendering the cellulose and hemicellulose highly available for subsequent use. The products are characterized by enhanced water-binding capacity of the cellulose as indicated by high water swellability. The products are also nontoxic and thereby useful as carbohydrate sources in ruminant feeds, as microbial feedstocks, and as sources of dietary fiber for humans and other monogastrics.

  • Patent number: 4753713
    Abstract: A sculptured structural fiberboard product is formed using a mold that includes porous forming areas which, in one embodiment, are porous forming mandrels movably mounted on the mold, and liquid impervious thimbles which removably cover the porous areas. A fiber network is formed as water is drained off through the porous areas and the thimbles are moved to gradually unveil the porous areas during the mat formation. When mandrels are used, the mandrels are withdrawn in cooperation with a pressing force applied to the mat to consolidate and dry the web. The porous areas can also act as heat and mass transfer means during consolidation and drying. An alternative embodiment permits formation of laminated products and another alternative embodiment permits close control over the product density during consolidation and drying.
