Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 52 words
A liquid metering and coating device comprising a porous permeation control layer adhered to the outside of a porous tubular support, said porous tubular support comprising an open-celled thermosetting polymerfoam having in its pores a reinforcing layer of silicone oil and silicone rubber adjacent the inner surface of the permeation control layer.
Claim 2
Dependent Claim 52 words
A liquid metering and coating device comprising a porous permeation control layer adhered to the outside of a porous tubular support, said porous tubular support comprising an open-celled thermosetting polymerfoam having in its pores a reinforcing layer of silicone oil and silicone rubber adjacent the inner surface of the permeation control layer.
Claim 3
Dependent Claim 48 words
The liquid metering and coating device of claim 1 having an oil-supply second layer of silicone oil and silicone rubber inside the reinforcing layer; said oil-supply layer having a silicone oil to silicone rubber ratio greater than the silicone oil to silicone rubber ratio of said reinforcing layer.
Claim 4
Dependent Claim 19 words
The liquid metering and coating device of claim 1, wherein the porous permeation control layer is porous expanded polytetrafluoroethylene.
Claim 5
Dependent Claim 45 words
The liquid metering and coating device of claim 3, wherein the pores of the porous permeation control layer contain silicone oil and silicone rubber in a silicone oil to silicone rubber ratio less than the silicone oil to silicone rubber ratio of the reinforcing layer.
Claim 6
Dependent Claim 48 words
The liquid metering and coating device of claim 4, having an oil-supply third layer of silicone oil and silicone rubber inside the reinforcing layer; said oil-supply layer having a silicone oil to silicone rubber ratio greater than the silicone oil to silicone rubber ratio of said reinforcing layer.
