Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A method for producing a structural material, comprising the steps of: collecting refuse; sorting said refuse into its carbonaceous, cellulosic, plastic and metallic components; wet-milling said carbonaceous, cellulosic and plastic components to form a pulp; removing the water from said pulp; fluffing and drying said pulp; spinning fibers from slag at said slag's point of production; blending said fibers with said dried pulp; shaping said fiber/pulp mass with said fluffed fibers irregularly arranged with portions of said pulp and fibers contacting other portions of said pulp and fibers forming at said points of contact a plurality of junctions and a plurality of irregular cells between said fibers and fluffed pulp; dehydrating said mass by heating; impregnating said mass with a resin solution; coating said fluffed pulp and fibers with said resin solution, such coating also coating over said junctions; and solidifying said resin coating holding said fluffed pulp and fiber together at said junctions by said solidified resin forming a structural material.
Claim 2
Independent Claim
162 words
A method for producing a structural material, comprising the steps of: collecting refuse; sorting said refuse into its carbonaceous, cellulosic, plastic and metallic components; wet-milling said carbonaceous, cellulosic and plastic components to form a pulp; removing the water from said pulp; fluffing and drying said pulp; spinning fibers from slag at said slag's point of production; blending said fibers with said dried pulp; shaping said fiber/pulp mass with said fluffed fibers irregularly arranged with portions of said pulp and fibers contacting other portions of said pulp and fibers forming at said points of contact a plurality of junctions and a plurality of irregular cells between said fibers and fluffed pulp; dehydrating said mass by heating; impregnating said mass with a resin solution; coating said fluffed pulp and fibers with said resin solution, such coating also coating over said junctions; and solidifying said resin coating holding said fluffed pulp and fiber together at said junctions by said solidified resin forming a structural material.
Claim 3
Dependent Claim
36 words
The method of claim 1 further including the steps of: carbonizing said structural material; metallizing the internal irregular cells formed in said structural material by ion deposition; and depositing a metallic plating on said metallized surfaces.
Claim 4
Dependent Claim
17 words
The method of claim 2 further including the step of: sealing the external surface of said structure.
