Abstract
Abstract A penetration seal for a surface opening and method of forming it by positioning a non-liquid, non-combustible substance in the void of the surface opening to provide a dam of desired thickness and applying an elastic coating over the dam and the object adjacent its passage through the dam to accommodate movement of the object relative to the dam without forming cracks in the closure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
55 words
A penetration seal for a surface opening having an object passing therethrough comprising a non-liquid, non-combustible substance substantially filling the void in the opening and an elastic coating over the substance and encapsulating the object adjacent its passage through the substance in the opening said elastic coating capable of elongating at least about 5 percent.
Claim 2
Dependent Claim
55 words
A penetration seal for a surface opening having an object passing therethrough comprising a non-liquid, non-combustible substance substantially filling the void in the opening and an elastic coating over the substance and encapsulating the object adjacent its passage through the substance in the opening said elastic coating capable of elongating at least about 5 percent.
Claim 3
Dependent Claim
20 words
The penetration seal of claim 1 wherein the substance includes an inorganic or organic binder for holding the substance together.
Claim 4
Dependent Claim
15 words
The penetration seal of claim 2 wherein the binder is phenolic coating or Kaolin clay.
Claim 5
Dependent Claim
46 words
The penetration seal of claim 1 wherein the weight of the substance is in the range from about 6 to about 20 pounds per cubic foot and wherein the thickness of the coating is in the range of about 0.010 to about 0.200 of an inch.
Claim 6
Dependent Claim
30 words
The penetration seal of claim 1 wherein the substance is from the group consisting essentially of silica fiber, mineral fiber, alumina silicate fiber, calcium silicate, ceramic fiber or refractory material.
Claim 7
Dependent Claim
16 words
The penetration seal of claim 1 wherein the elastic coating comprises elastic binder, filler and water.
Claim 8
Dependent Claim
29 words
The penetration seal of claim 1 wherein the elastic coating comprises a binder which binder consists essentially of a water based, elastic resinous emulsion thermoplastic, a filler and water.
Claim 9
Dependent Claim
15 words
The penetration seal of claim 7 wherein the filler is TiO 2 or alumina trihydrate.
Claim 10
Dependent Claim
43 words
The penetration seal of claims 6, 7 or 8 wherein the elastic coating is any one or more from the group of acrylic elastomer latex, acrylic modified polyvinyl emulsion, plasticized polyvinyl acetate latex polymers, polyvinyl ethylene latex polymers or plasticized polyvinyl latex polymers.
Claim 11
Dependent Claim
40 words
The penetration seal of claim 1 wherein the elastic coating comprises any one or more from the group of acrylic elastomer latex, acrylic modified polyvinyl emulsion, plasticized polyvinyl acetate latex polymers, polyvinyl ethylene latex polymers or plasticized polyvinyl latex polymers.
Claim 12
Dependent Claim
63 words
The penetration seal of claims 1, or 2, or 3, or 4, or 5, or 6, or 7, or 8 or 10 wherein the range by weight of the binder is about 25% to about 75%; the range by weight of the filler is about 15% to about 60%; and the range by weight of the water is about 7% to about 31%.
Claim 13
Independent Claim
75 words
A method of forming a penetration seal in a surface opening having an object passing therethrough comprising the steps of: positioning a non-liquid, non-combustible substance in the void of the surface opening to provide a blocking dam of desired thickness; and applying an elastic coating over the dam and encapsulating the object adjacent its passage through the dam to accommodate movement of the object relative to the dam without forming cracks in the penetration seal.
Claim 14
Independent Claim
75 words
A method of forming a penetration seal in a surface opening having an object passing therethrough comprising the steps of: positioning a non-liquid, non-combustible substance in the void of the surface opening to provide a blocking dam of desired thickness; and applying an elastic coating over the dam and encapsulating the object adjacent its passage through the dam to accommodate movement of the object relative to the dam without forming cracks in the penetration seal.
