Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
100 words
A method of sealing an exposed area of an electrical cable comprising the steps of: forming an enclosure around said exposed area; sealably attaching said enclosure to said cable adjacent said exposed area; providing an access opening in said enclosure; interposing selectively closable flexible inlet means into said access opening; filling said enclosure through said inlet means with an encapsulant, said encapsulant substantially surrounding said exposed area; closing said inlet means, thereby preventing escape of said encapsulant; sealably wrapping said filled enclosure and said closed flexible inlet means with sealing tape; and placing a sealing sleeve around said wrapped enclosure.
Claim 2
Independent Claim
100 words
A method of sealing an exposed area of an electrical cable comprising the steps of: forming an enclosure around said exposed area; sealably attaching said enclosure to said cable adjacent said exposed area; providing an access opening in said enclosure; interposing selectively closable flexible inlet means into said access opening; filling said enclosure through said inlet means with an encapsulant, said encapsulant substantially surrounding said exposed area; closing said inlet means, thereby preventing escape of said encapsulant; sealably wrapping said filled enclosure and said closed flexible inlet means with sealing tape; and placing a sealing sleeve around said wrapped enclosure.
Claim 3
Dependent Claim
25 words
The method in accordance with claim 1 wherein said forming step further comprises: forming said enclosure into an elongate trough having an open upper end.
Claim 4
Dependent Claim
30 words
The method in accordance with claim 2 wherein said sealing step comprises: sealing the opposite elongate ends of said trough to said cable at either side of said exposed area.
Claim 5
Dependent Claim
31 words
The method in accordance with claim 3 wherein said providing step comprises: partially closing said open upper end of said trough and thereby providing said access opening along an extent thereof.
Claim 6
Dependent Claim
21 words
The method in accordance with claim 1 wherein said closing step comprises: manually closing said sealing member of said inlet means.
Claim 7
Dependent Claim
25 words

Claim 8
Dependent Claim
24 words
The method in accordance with claim 1 further including the step of: sealably securing said inlet means to said enclosure adjacent said access opening.
Claim 9
Independent Claim
82 words
A method of sealably covering an exposed portion of an electrical cable comprising: enclosing said exposed portion with an elongate self-adhering enclosure sheet; providing an access opening in said enclosure sheet; inserting a sealable flexible inlet member in said opening; adhering a portion of said inlet member to said enclosure sheet; pouring an encapsulant into and through said inlet member to surround said exposed portion; sealing said inlet member; and wrapping said enclosure sheet and said flexible inlet member with sealing tape.
Claim 10
Independent Claim
82 words
A method of sealably covering an exposed portion of an electrical cable comprising: enclosing said exposed portion with an elongate self-adhering enclosure sheet; providing an access opening in said enclosure sheet; inserting a sealable flexible inlet member in said opening; adhering a portion of said inlet member to said enclosure sheet; pouring an encapsulant into and through said inlet member to surround said exposed portion; sealing said inlet member; and wrapping said enclosure sheet and said flexible inlet member with sealing tape.
Claim 11
Dependent Claim
39 words
The method in accordance with claim 8 wherein said enclosing step includes: folding said enclosure sheet around said exposed portion; sealably adhering at least one longitudinal end of said enclosure sheet to said cable adjacent to the exposed portion.
Claim 12
Dependent Claim
46 words
The method in accordance with claim 9 wherein the folding step further comprises: sealably adhering the other longitudinal end of said enclosure sheet to said cable; and wherein said providing step further comprises providing said access opening longitudinally between the two said sealably adhered longitudinal ends.
Claim 13
Dependent Claim
20 words
The method in accordance with claim 8 further comprising the step of: wrapping said exposed portion with a protective layer.
Claim 14
Dependent Claim
84 words
In a method of sealing an exposed area of an electrical cable including the steps of providing an enclosure around said exposed area, filling said enclosure with an encapsulant, and sealably covering said enclosure, the improvement comprising the steps of: interposing a selectively openable inlet member in said enclosure for passage of said encapsulant; closing said inlet member upon receipt of said encapsulant; folding said inlet member in said enclosure upon sealably covering said enclosure; and sealably adhering said inlet member to said enclosure.
Claim 15
Dependent Claim
84 words
In a method of sealing an exposed area of an electrical cable including the steps of providing an enclosure around said exposed area, filling said enclosure with an encapsulant, and sealably covering said enclosure, the improvement comprising the steps of: interposing a selectively openable inlet member in said enclosure for passage of said encapsulant; closing said inlet member upon receipt of said encapsulant; folding said inlet member in said enclosure upon sealably covering said enclosure; and sealably adhering said inlet member to said enclosure.
Claim 16
Dependent Claim
18 words
The method in accordance with claim 12 wherein said closing step further comprises: manually closing said inlet member.
