Abstract
Abstract A heat-recoverable sleeve for enclosing splices or joints in pressurized cables or supply lines is given increased resistance to peeling away from the cable or line by insertion of auxiliary means, preferably a U- or V-shaped flexible strip, which may be heat-recoverable, between the sleeve and the cable or supply line. The ends of the strip are preferably closed and are preferably overlapped and bonded to each other when the strip is placed around the cable or supply line. A release foil may be positioned inside the U- or V-shape of the strip to resist bonding together of the opposed arms thereof, and the foil may carry adhesive to bond it to one of the arms and may protrude beyond the ends of the arms so that the foil adhesive can help to locate the strip on the cable or supply line.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
129 words
A casing for a pressurized segment of an elongate substrate, comprising a sleeve positionable about the substrate segment to define an enclosure thereabout, said sleeve tapering at the ends thereof to meet the substrate when said sleeve is assembled with the substrate; and an auxiliary member positionable about the substrate between the substrate and said sleeve at the region where the substrate and said sleeve meet, said auxiliary member being of flexible sheet material having inner and outer arms in cross-section defining an annular channel with the concavity of said channel facing the interior of said enclosure and adapted to allow said channel to open out responsive to pressure within said sleeve, the inner and outer arms of said channel being bondable to the substrate and said sleeve respectively.
Claim 2
Dependent Claim
129 words
A casing for a pressurized segment of an elongate substrate, comprising a sleeve positionable about the substrate segment to define an enclosure thereabout, said sleeve tapering at the ends thereof to meet the substrate when said sleeve is assembled with the substrate; and an auxiliary member positionable about the substrate between the substrate and said sleeve at the region where the substrate and said sleeve meet, said auxiliary member being of flexible sheet material having inner and outer arms in cross-section defining an annular channel with the concavity of said channel facing the interior of said enclosure and adapted to allow said channel to open out responsive to pressure within said sleeve, the inner and outer arms of said channel being bondable to the substrate and said sleeve respectively.
Claim 3
Dependent Claim
11 words
The casing of claim 1 wherein said sleeve is heat recoverable.
Claim 4
Dependent Claim
21 words
The casing of claim 1 wherein said inner arm of said channel includes bonding material capable of bonding to the substrate.
Claim 5
Dependent Claim
21 words
The casing of claim 3 further including additional bonding material positionable between said outer arm of said channel and said sleeve.
Claim 6
Dependent Claim
14 words
The casing of claims 3 or 4 wherein said bonding material is hot-melt adhesive.
Claim 7
Dependent Claim
13 words
The casing of claims 3 or 4 wherein said bonding material is mastic.
Claim 8
Dependent Claim
26 words
The casing of claim 1 wherein said auxiliary member includes spring means within said channel for holding said auxiliary member in position wrapped about the substrate.
Claim 9
Dependent Claim
24 words
The casing according to claim 1 wherein said inner and outer arms are affixed to one another at the ends of said auxiliary member.
Claim 10
Dependent Claim
38 words
The casing of claim 1 further including a strip extending substantially the length of said auxiliary member, being positioned in said channel and extending outwardly therefrom, said strip preventing the bonding of said inner and outer arms together.
Claim 11
Dependent Claim
24 words
The casing of claim 9 wherein said strip includes bonding material on one side thereof and a nonstick surface on the other surface thereof.
Claim 12
Dependent Claim
13 words
The casing of claim 1 wherein said auxiliary member is of heat-shrinkable material.
Claim 13
Dependent Claim
126 words
A casing for a pressurized segment of an elongate substrate comprising a sleeve positioned about the substrate segment to define an enclosure thereabout, said sleeve tapering at the ends thereof to meet the substrate; an auxiliary member positioned about the substrate between the substrate and said sleeve at the region where the substrate and said sleeve meet, said auxiliary member being of flexible sheet material having inner and outer arms in cross-section defining an annular channel with the concavity of said channel facing the interior of said enclosure and adapted to allow said channel to open out responsive to pressure within said sleeve, said inner arm of said channel being bonded to the substrate and said outer arm of said channel being bonded to said sleeve.
Claim 14
Dependent Claim
126 words
A casing for a pressurized segment of an elongate substrate comprising a sleeve positioned about the substrate segment to define an enclosure thereabout, said sleeve tapering at the ends thereof to meet the substrate; an auxiliary member positioned about the substrate between the substrate and said sleeve at the region where the substrate and said sleeve meet, said auxiliary member being of flexible sheet material having inner and outer arms in cross-section defining an annular channel with the concavity of said channel facing the interior of said enclosure and adapted to allow said channel to open out responsive to pressure within said sleeve, said inner arm of said channel being bonded to the substrate and said outer arm of said channel being bonded to said sleeve.
Claim 15
Dependent Claim
19 words
The casing of claim 12 further including a second auxiliary member at the opposite corresponding position of said casing.
Claim 16
Dependent Claim
34 words
The casing of claim 12 further including a strip positioned in said channel, extending substantially the length thereof and extending outwardly of said channel, said strip having bonding material on a first side thereof.
Claim 17
