  • Patent number: 5583165
    Abstract: A soil top dressing is comprised of a mixture of sand, clay, a plasticizer material, water, and a coloring pigment, if desired. The components of the soil composition are preferably present in the following proportions by weight: sand 50-70%; clay 10-40%; plasticizer 0.5-5.0%; water 5-20%; coloring pigment 1-5%; all coated with kelp meal granules (5-20%). The method of making the invention involves continuously mixing a portion of the sand and the plasticizer in an agitation mixer. The sand becomes coated with the plasticizer, whereupon a quantity of clay is then added, followed by an additional portion of the plasticizing material. It is particularly important that the sand particles become coated with the plasticizing compound and clay. The coloring pigments are added and mixed thereafter. The foregoing particles are thereupon coated with particles of kelp meal. As soon as complete mixing takes place, material can be immediately transferred from the mixer to suitable packaging.

  • Patent number: 4364979
    Abstract: Particle board contains, as a fibrous material with good structural properties, at least a proportion of chicory root particles. Preferably the chicory is mixed with bagasse fibres to provide strength to the board, and a filler in the form of coffee grounds is included. The coffee and chicory constituents are conveniently obtained as wastes from the manufacture of instant coffee.

  • Patent number: 4362827
    Abstract: The invention concerns the production of particle board with a very substantially lowered formaldehyde emission as well as suitable binding agents. According to the invention the binding agent used in the production of the board is a combination of a polyisocyanate with a aminoplast resin containing 0.25 to 0.625 moles of formaldehyde per mole equivalent of aminogroups. The particle boards thus obtained possess satisfactory mechanical properties and a strongly reduced formaldehyde emission.
