  • Low density pet litters and methods of making and using such pet litters
    Patent number: 11457606
    Abstract: Compacting expanded perlite fines in the presence of a clay and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a clumping agent to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.
    Type: Grant
    Filed: October 11, 2019
    Date of Patent: October 4, 2022
    Assignee: SOCIÉTÉ DES PRODUITS NESTLÉ S.A.

  • LOW DENSITY PET LITTERS AND METHODS OF MAKING AND USING SUCH PET LITTERS
    Publication number: 20210076635
    Abstract: Compacting expanded perlite fines in the presence of a small amount of binder (starch and/or clay) and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a small amount of clumping agent (e.g., guar gum) to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.

  • Rotary forming devices and methods for using such devices
    Patent number: 8602766
    Abstract: Rotary forming devices and methods of using the rotary forming devices for producing products such as filled and unfilled “pillow” shaped products. In an embodiment, the invention provides a device comprising a housing comprising a die plate defining a plurality of outlets. The housing defines an inlet. A race plate is attached to the die plate. The race plate circumscribes the outlets of the die plate. A forming wheel is rotatably attached to the die plate. A motor assembly is attached to the forming wheel. The motor assembly is constructed and arranged to rotate the forming wheel in a hypocycloid motion.
