Abstract
Abstract A plug assembly for encircling a cable and encapsulating it within a conduit includes a first and second ring members, each of which is formed of resilient material and has an inner wall conformable to a circumferential portion of the cable's outer surface. A rigid spacer is disposed between the first and second ring members for defining a sealant-receiving channel therebetween. Sealant material, such as a silicone compound, is dispensed within the channel, and a compression means associated with the plug assembly is operable for deforming the first and second ring members axially and radially, thereby to deform the channel so that at least some sealant material received in the channel is displaced into the region between the inner walls of the first and second ring members and corresponding portions of the cable's outer surface to provide a cushion/sealant between the ring members and the cable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A plug assembly for encircling at least one cable and encapsulating it within a conduit comprising: a first ring member formed of resilient material having an inner wall conformable to a circumferential portion of a cable's outer surface; a second ring member formed of resilient material disposed adjacent the first ring member, the second ring member also having an inner wall conformable to a circumferential portion of a cable's outer surface; substantially rigid spacer means disposed between the first and second ring members for defining a sealant-receiving channel therebetween; and compression means operable for deforming the first and second ring members axially and radially thereby to deform the channel so that at least some sealant material received in the channel is displaced into the region between the inner walls of the first and second ring members and corresponding portions of a cable's outer surface to provide a cushion/sealant between the ring members and a cable.
Claim 2
Dependent Claim
155 words
A plug assembly for encircling at least one cable and encapsulating it within a conduit comprising: a first ring member formed of resilient material having an inner wall conformable to a circumferential portion of a cable's outer surface; a second ring member formed of resilient material disposed adjacent the first ring member, the second ring member also having an inner wall conformable to a circumferential portion of a cable's outer surface; substantially rigid spacer means disposed between the first and second ring members for defining a sealant-receiving channel therebetween; and compression means operable for deforming the first and second ring members axially and radially thereby to deform the channel so that at least some sealant material received in the channel is displaced into the region between the inner walls of the first and second ring members and corresponding portions of a cable's outer surface to provide a cushion/sealant between the ring members and a cable.
Claim 3
Dependent Claim
64 words
The plug assembly of claim 1 wherein the compression means includes rigid members mounted on the external sides of each ring member, and biasing means interconnecting the rigid members, ring members and spacer means selectively positionable for displacing the rigid members toward one another to compress the first and second ring members so that the channel decreases in width thereby urging sealant material therefrom.
Claim 4
Dependent Claim
28 words
The plug assembly of claim 2 wherein the biasing means includes elongate, adjustable fastening means disposed through apertures aligned in the rigid members, ring members and spacer means.
Claim 5
Dependent Claim
19 words
The plug assembly of claim 3 wherein the spacer means includes an arcuate surface facing internally toward a cable.
Claim 6
Dependent Claim
28 words
The plug assembly of claim 4 wherein the ring members are axially split to enable the ring members to be splayed outwardly for initial positioning around a cable.
Claim 7
Independent Claim
156 words
A method for encircling at least one cable and encapsulating it within a conduit comprising: providing a plug assembly defined by a pair of spaced-apart first and second ring members, each of which is formed of resilient material having an inner wall conformable to a circumferential portion of a cable's outer surface, the plug assembly also including a rigid spacer disposed between the first and second ring members for defining a sealant-receiving channel therebetween; dispensing sealant material into the channel; positioning the plug assembly around a cable; positioning the plug assembly within a conduit; and deforming the first and second ring members axially and radially thereby to deform the channel so that at least some sealant material received in the channel is displaced into the region between the inner walls of the first and second ring members and corresponding portions of a cable's outer surface to provide a cushion/sealant between the ring members and a cable.
Claim 8
Independent Claim
156 words
A method for encircling at least one cable and encapsulating it within a conduit comprising: providing a plug assembly defined by a pair of spaced-apart first and second ring members, each of which is formed of resilient material having an inner wall conformable to a circumferential portion of a cable's outer surface, the plug assembly also including a rigid spacer disposed between the first and second ring members for defining a sealant-receiving channel therebetween; dispensing sealant material into the channel; positioning the plug assembly around a cable; positioning the plug assembly within a conduit; and deforming the first and second ring members axially and radially thereby to deform the channel so that at least some sealant material received in the channel is displaced into the region between the inner walls of the first and second ring members and corresponding portions of a cable's outer surface to provide a cushion/sealant between the ring members and a cable.
Claim 9
Dependent Claim
31 words
The method of claim 6 wherein the deforming step is accomplished by compressing the first and second ring members so that the channel decreases in width thereby urging sealant material therefrom.
Claim 10
Dependent Claim
49 words
The method of claim 7 wherein the displacing of sealant material into the region between the inner walls of the first and second ring members and corresponding portions of a cable's outer surface is accompanied by equal radial forces directed against the corresponding portions of a cable's outer surface.
