Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
18 words
A method as of claim 1, wherein the induction of said electromagnetic field equals at least 0.08 Tesla.
Claim 2
Dependent Claim
28 words
The method of claim 1, further including the steps of separating the ferromagnetic bodies from the loose ingredients and milling the loose ingredients together with a rubber material.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein the ferromagnetic bodies are cylindrical in shape.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the filler component of the loose ingredients is selected from the group consisting of kaolin and chalk.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein the ferromagnetic bodies are made of a material selected from the group consisting of steel, iron and nickel.
Claim 6
Dependent Claim
32 words
The method of claim 1 wherein there is initially added to the loose ingredients prior to treatment in the rotating electromagnetic field, a modifying agent in the form of a cation surfactant.
