  • Patent number: 8227364
    Abstract: The present invention relates to a porous planting medium containing minerals and a method for preparing the same, and more particularly, to a porous planting medium prepared by using bentonite and/or zeolite and minerals for promoting plant growth as raw materials and a method for preparing the same. The porous planting medium containing minerals according to the present invention can provide places where plants can grow due to the pores therein and create the ideal environment for plant growth due to minerals used therein. Also, since it is installed in a building with plant seeds germinated therein, it can provide effects of interior decoration, wood bathing due to anion generation and a pleasant interior environment.

  • Patent number: 6162273
    Abstract: A floral foam which contains nutrients an preservatives for cut flowers is described, which floral foam has been pre-injected with nutrients and preservatives in an amount of 8-12 g per dm.sup.3 water which can be absorbed by the foam. A method for the production of such a floral foam is also described. The floral foam is pre-injected with 10-30 ml of a solution containing nutrients and preservatives per dm.sup.3 water which can be absorbed by the floral foam.

  • Patent number: 5840210
    Abstract: Disclosed are dry particulate compositions containing an anionic sulfonate or sulfate surfactant, fatty mono- or di-ethanolamide, alcohol, sugar and maltodextrin. The dry compositions readily disperse in water to form formulations which can form voluminous, stable, environmentally benign foams useful, for instance, in marking outdoor areas.

  • Patent number: 5730773
    Abstract: The present invention is a device and method for selectively dispensing at least one target compound into a selected environment. A target compound is dissolved within an elastomer compound in a concentration that supersaturates the elastomer compound. The elastomer compound is then shaped into a selected form that is conducive to placement within the selected environment. The target compound within the elastomer compound begins to bloom to the surface of the elastomer compound where it is exposed to the surrounding environment. The bloom of the target compound into the surrounding environment continues until the concentration of the target compound within the elastomer compound reaches its saturation point. As such, the duration of the bloom of the target compound from the elastomer compound can be regulated by the concentration of the target compound within the elastomer compound, the volume of the elastomer compound and the surface area of the elastomer compound.

  • Patent number: 5096616
    Abstract: Aqueous thixotropic foam-producing chemical compositions are presented which are comprised of an anionic sulfonate or sulfate surfactant, a fatty acid having 10-30 carbon atoms, an acrylic-based thixotropic thickener, an acrylic acid polymer processing aide and a base present in a concentration sufficiently high to neutralize all of the acid components of the mixture and adjust the pH to above 7.5. The thixotropic foam-producing compositions are useful for producing thixotropic foams which have the ability to resist slumping on sloped surfaces. Also disclosed is a process for mixing highly viscous, low density chemical foaming compositions with water without causing foaming of the resulting mixture.

  • Patent number: 4315761
    Abstract: The object of the invention is to use a finely divided calcium hydrosilicate material, in particular aerated or foamed concrete, as a substance for binding and clearing of urine and excrements of the kind excreted for instance by our pet animals. This material gives rapid and effective drying of the excrements, which, particularly if the material is combined with gypsum as a bond-improving agent, become extremely easy to remove or clear.
