Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
33 words
Animal control litter comprised of light weight aggregate expanded to form porous surfaces by subjecting the aggregate to a temperature of 1800 degrees F., a clumping agent, surfactant and an odor control agent.
Claim 2
Dependent Claim
33 words
Animal control litter comprised of light weight aggregate expanded to form porous surfaces by subjecting the aggregate to a temperature of 1800 degrees F., a clumping agent, surfactant and an odor control agent.
Claim 3
Dependent Claim
27 words
The animal control litter of claim 1 in which said light weight aggregate is selected from the class consisting of perlite, vermiculite, herculite, rice hulls and zeolite.
Claim 4
Dependent Claim
46 words
The animal control litter of claim 1 in which the component parts are present in the following amounts, 89.6 percent by weight of expanded aggregate, 00.4 percent by weight of odor control agent, 07.0 percent by weight of clumping agent, 03.0 percent by weight of surfactant.
Claim 5
Dependent Claim
28 words
The animal control litter of claim 1 in which the odor control agent is D-ODOR, the surfactant is an alkylphenol ethoxylate and the clumping agent is AgRho DR-2000.
Claim 6
Dependent Claim
18 words
The animal control litter of claim 1 in which the light weight aggregate consists of perlite and vermiculite.
Claim 7
Independent Claim
67 words
The method of manufacturing an animal control litter comprising the steps of subjecting an amount of perlite to a temperature of at least 1800 degrees F. to expand the perlite to form porous perlite, adding to the expanded perlite a clumping agent, a surfactant and an odor control agent, stirring the above named materials to add the agents and the surfactant to pores of the porous perlite.
Claim 8
Independent Claim
67 words
The method of manufacturing an animal control litter comprising the steps of subjecting an amount of perlite to a temperature of at least 1800 degrees F. to expand the perlite to form porous perlite, adding to the expanded perlite a clumping agent, a surfactant and an odor control agent, stirring the above named materials to add the agents and the surfactant to pores of the porous perlite.
