Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A method of making a hollow pressure vessel around an elongate substrate, which comprises: (A) providing around the substrate a liner having a larger central section and smaller end sections; (B) providing around the liner a hollow article having at least one recoverable outlet portion such that the substrate extends through said outlet portion, the article comprising a composite structure recoverable by virtue of a recoverable fibre component thereof; and (C) recovering into engagement with the substrate one or more outlet portions only of the structure.
Claim 2
Independent Claim
86 words
A method of making a hollow pressure vessel around an elongate substrate, which comprises: (A) providing around the substrate a liner having a larger central section and smaller end sections; (B) providing around the liner a hollow article having at least one recoverable outlet portion such that the substrate extends through said outlet portion, the article comprising a composite structure recoverable by virtue of a recoverable fibre component thereof; and (C) recovering into engagement with the substrate one or more outlet portions only of the structure.
Claim 3
Dependent Claim
26 words
A method according to claim 1, in which the substrate comprises a cable splice and the hollow article, when installed, has at least two outlet portions.
Claim 4
Dependent Claim
14 words
A method according to claim 2, in which the hollow article comprises a sleeve.
Claim 5
Dependent Claim
14 words
A method according to claim 3, in which the sleeve is a wrap-around sleeve.
Claim 6
Dependent Claim
57 words
A method according to claim 1, in which the pressure vessel is formed around at least two branching substrates, the method additionally comprising dividing an outlet of the article into at least two said recoverable outlet portions by means of a branch-off clip, such that each said recoverable outlet portion can receive one of the branching substrates.
Claim 7
Dependent Claim
17 words
A method according to claim 1, in which the recoverable fibres are provided by a recoverable fabric.
Claim 8
Dependent Claim
12 words
A method according to claim 1, in which the fibres are cross-linked.
Claim 9
Dependent Claim
24 words
A method according to claim 1, which additionally comprises formation of a bond between an outlet portion and the substrate which passes through it.
Claim 10
Dependent Claim
43 words
A method according to claim 1, which additionally comprises positioning around the substrate at a position where it will engage an outlet portion, means for reducing the tendency of pressure within the vessel to cause disengagement between the substrate and the outlet portion.
