Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A method for reducing the amount of particles which become airborne during the dismantling of wall structures comprising the steps of: providing a reservoir for receiving a dissipative foam by constructing a reservoir wall spaced a distance from the wall structures, the reservoir wall cooperating with a portion of the wall structures to define the reservoir and retain the foam; spraying said foam into the reservoir to provide a reservoir of foam; spraying a dissipative foam on the wall structures to be dismantled; and dismantling portions of said wall structures and directing substantially all of the dismantled portions of the wall structures into the reservoir of foam until the wall structures substantially are dismantled.
Claim 2
Independent Claim
114 words
A method for reducing the amount of particles which become airborne during the dismantling of wall structures comprising the steps of: providing a reservoir for receiving a dissipative foam by constructing a reservoir wall spaced a distance from the wall structures, the reservoir wall cooperating with a portion of the wall structures to define the reservoir and retain the foam; spraying said foam into the reservoir to provide a reservoir of foam; spraying a dissipative foam on the wall structures to be dismantled; and dismantling portions of said wall structures and directing substantially all of the dismantled portions of the wall structures into the reservoir of foam until the wall structures substantially are dismantled.
Claim 3
Dependent Claim
65 words
The method of claim 1 wherein the step of providing the reservoir is defined further as providing a reservoir having a predetermined volume adequate to accommodate a predetermined volume of said foam sufficient to receive the dismantled portions of the wall structures, and the step of spraying the foam into the reservoir is defined further as spraying the predetermined volume of foam into the reservoir.
Claim 4
Dependent Claim
30 words
The method of claim 1 wherein the step of spraying the foam on the wall structures is defined further as spraying the foam on the sides of the wall structures.
Claim 5
Dependent Claim
77 words
The method of claim 3 wherein the step of spraying the foam on the sides of the wall structures is defined further to include the steps of: providing water; providing foam concentrate; mixing the water and foam concentrate; and expanding the mixed water and foam concentrate to provide the foam having a predetermined density sufficient to facilitate the foam substantially remaining in place on the sides of the wall structures during the dismantling of the wall structures.
Claim 6
Dependent Claim
76 words
The method of claim 4 wherein the step of spraying the foam into the reservoir is defined further to include the steps of: providing water; providing foam concentrate; mixing the water and foam concentrate; and expanding the mixed water and foam concentrate to provide the foam having a predetermined density, the density of the foam providing the reservoir of foam being less than the density of the foam sprayed on the sides of the wall structures.
Claim 7
Dependent Claim
22 words
The method of claim 1 wherein the wall structures are defined further as being contaminated by way of exposure to radioactive materials.
Claim 8
Dependent Claim
29 words
The method of claim 1 defined further to include the steps of: permitting the foam to dissipate after dismantling the wall structures; and disposing of the dismantled wall structures.
Claim 9
Independent Claim
103 words
A method for reducing the amount of particles which become airborne during the dismantling of wall structures comprising the steps of: providing a reservoir for receiving a dissipative foam by constructing a reservoir wall spaced a distance from the wall structures, the reservoir wall cooperating with a portion of the wall structures to define the reservoir and retain the foam; spraying said foam into the reservoir to provide a reservoir of foam; and dismantling portions of said wall structures and directing substantially all of the dismantled portions of the wall structures into the reservoir of foam until the wall structures substantially are dismantled.
Claim 10
Independent Claim
103 words
A method for reducing the amount of particles which become airborne during the dismantling of wall structures comprising the steps of: providing a reservoir for receiving a dissipative foam by constructing a reservoir wall spaced a distance from the wall structures, the reservoir wall cooperating with a portion of the wall structures to define the reservoir and retain the foam; spraying said foam into the reservoir to provide a reservoir of foam; and dismantling portions of said wall structures and directing substantially all of the dismantled portions of the wall structures into the reservoir of foam until the wall structures substantially are dismantled.
Claim 11
Dependent Claim
66 words
The method of claim 8 wherein the step of providing the reservoir is defined further as providing a reservoir having a predetermined volume adequate to accommodate a predetermined volume of the foam sufficient to receive the dismantled portions of the wall structures and wherein the step of spraying the foam into the reservoir is defined further as spraying the predetermined volume of foam into the reservoir.
Claim 12
Dependent Claim
22 words
The method of claim 8 wherein the wall structures are defined further as being contaminated by way of exposure to radioactive materials.
Claim 13
Dependent Claim
29 words
The method of claim 8 defined further to include the steps of: permitting the foam to dissipate after dismantling the wall structures; and disposing of the dismantled wall structures.
