  • Patent number: 7337747
    Abstract: A particulate non-clumping animal litter composition is disclosed. The composition comprises non-clumping absorbent particles bound to magnetically-attractable metal particles such that substantially all particles of the animal litter composition are attracted to a magnetic surface. The animal litter composition exhibits favorable properties such as absorbency, resiliency, homogeneity, and particle size. Methods of production for non-clumping animal litter compositions are also disclosed that employ sufficient shear to bind the non-clumping absorbent particulate material to the magnetically-attractable metal particles such that the animal litter compositions exhibit favorable properties. A method and apparatus for the collection of magnetically-attractable animal litter particles are also disclosed.
    Type: Grant

  • Publication number: 20070210005
    Abstract: It has been found that phosphorous-containing and oxyanion compounds can be removed efficiently and economically by adsorption with cation-exchanged aluminosilicates that are ion-exchanged in a concentrated aluminosilicate composition containing the aluminosilicate, the exchange cations, and only about 15% to about 50% by weight water, based on the total weight of the aluminosilicate and water. Further, the ion-exchange process described herein has been found to be effective, in addition to those complexing or ion-exchange elements described in the Douglas '383 patent, when complexed or ion-exchanged with one or more elements of Group VIII (Fe, Co, Mi, Ru, Rh, Pd, Re, Os, Ir), Group IB (Cn, Ag, Au), and Group IIB (Zn, Cl, Hg).

  • Publication number: 20070169710
    Abstract: A particulate clumping animal litter composition is disclosed. The composition comprises water-swellable smectite clay particles bound to magnetically-attractable metal particles such that substantially all particles of the animal litter composition are attracted to a magnetic surface. The animal litter composition exhibits favorable properties such as absorbency, resiliency, homogeneity, clump strength, and particle size. Methods of production for clumping animal litter compositions are also disclosed that employ sufficient shear to bind the water-swellable smectite clay particles to the magnetically-attractable metal particles such that the animal litter compositions exhibit favorable properties. A method and apparatus for the collection of magnetically-attractable animal litter particles are also disclosed.
