Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
64 words
The method of dehydrating wet soil, comprising, heating particulate aggregate material to a temperature substantially above the existing atmospheric temperature, spreading said heated aggregate on the wet soil to be dehydrated, cutting a plurality of slits in said soil to permit said heated aggregate to fall into the slits, whereby the heated aggregate will heat the soil and induce evaporation of the moisture therein.
Claim 2
Independent Claim
64 words
The method of dehydrating wet soil, comprising, heating particulate aggregate material to a temperature substantially above the existing atmospheric temperature, spreading said heated aggregate on the wet soil to be dehydrated, cutting a plurality of slits in said soil to permit said heated aggregate to fall into the slits, whereby the heated aggregate will heat the soil and induce evaporation of the moisture therein.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein said slits are cut in the soil before said heated aggregate is deposited on the soil.
Claim 4
Dependent Claim
17 words
The method of claim 1 wherein said slits are cut in a parallel direction with each other.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein said slits are substantially narrow in proportion to their depth.
Claim 6
Dependent Claim
49 words
The method of claim 1 wherein said aggregate is of a texture and of a sufficient thickness on said ground, and the slits are of sufficient width and depth, that said slits will be filled by said aggregate through the force of gravity as said slits are being cut.
Claim 7
Dependent Claim
19 words
The method of claim 1 wherein said slits have a depth in excess of ten times the width thereof.
Claim 8
Dependent Claim
18 words
The method of claim 3 wherein the slits are spaced apart a distance less than the depth thereof.
Claim 9
Dependent Claim
20 words
The method of claim 1 wherein said aggregate is heated to a temperature of between 125* Fahrenheit to 600* Fahrenheit.
