Abstract
Abstract An assembly for enclosing a telecommunication cable splice comprising a wraparound sleeve having longitudinal edges which can be brought together and secured by for example a metal channel. A seal is made between these edges by an internal sealing member which bridges the abutting edges of the sleeve and is urged into contact with the sleeve by expansive urging means between the sealing member and underlying cable splice. The urging means is preferably a foam strip.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
90 words
An assembly for enclosing a substrate, comprising: a wraparound sleeve having two longitudinal edge regions which can be brought together around the substrate; closure means for holding together said edge regions to form a closure for the wraparound sleeve; a sealing member arranged inside the sleeve and extending at least partially longitudinally beneath and bridging said edge regions when they are brought together; and means situated radially inwardly of the sealing member for urging the sealing member outwardly against the edge regions to form a seal between said edge regions.
Claim 2
Dependent Claim
90 words
An assembly for enclosing a substrate, comprising: a wraparound sleeve having two longitudinal edge regions which can be brought together around the substrate; closure means for holding together said edge regions to form a closure for the wraparound sleeve; a sealing member arranged inside the sleeve and extending at least partially longitudinally beneath and bridging said edge regions when they are brought together; and means situated radially inwardly of the sealing member for urging the sealing member outwardly against the edge regions to form a seal between said edge regions.
Claim 3
Dependent Claim
45 words
An assembly according to claim 1, wherein the closure means are closure members, one situated adjacent each edge region, which can be brought together to effect said closure; the sealing member bridging the gap between the closure members when said edge regions are brought together.
Claim 4
Dependent Claim
16 words
An assembly according to claim 1, wherein the sleeve and the sealing member are discrete components.
Claim 5
Dependent Claim
16 words
An assembly according to claim 1, wherein the means for urging comprises an expansible foam material.
Claim 6
Dependent Claim
20 words

Claim 8
Dependent Claim
20 words
An assembly according to claim 1, wherein the sealing member and means for urging are provided integrally with one another.
Claim 9
Dependent Claim
47 words
An assembly according to claim 1, wherein the sealing member comprises a strip of polymeric material coated on one major surface thereof with an adhesive, and wherein said means for urging comprises a strip of foam material disposed on the other major surface of the sealing strip.
Claim 10
Dependent Claim
14 words
An assembly according to claim 1, additionally comprising a support for said wraparound sleeve.
Claim 11
Dependent Claim
22 words

Claim 12
Dependent Claim
15 words
An assembly according to claim 9, wherein the support comprises a generally cylindrical metal canister.
Claim 13
Dependent Claim
34 words
An assembly according to claim 11, wherein the support is longitudinally slit and of variable cross-sectional size, being biased to an expanded configuration in order that it may act as said means for urging.
Claim 14
Dependent Claim
16 words
An assembly according to claim 9, wherein the support comprises end rings interconnected by longitudinal bars.
Claim 15
Dependent Claim
17 words
An assembly according to claim 13, wherein one of said longitudinal bars acts as said urging means.

Claim 19
Dependent Claim
19 words
An assembly according to claim 1, wherein the wraparound sleeve is recovered along at least part of its length.
Claim 20
Independent Claim
72 words
A method of enclosing a substrate wherein a wraparound sleeve is closed around the substrate by closure means which hold together longitudinal edge regions of the sleeve, a sealing member is located internally adjacent the sleeve to extend at least along said edge regions and the sleeve and sealing member are urged together by an urging means situated radially inwardly of the sealing member to effect a seal between said edge regions.
Claim 21
Independent Claim
72 words
A method of enclosing a substrate wherein a wraparound sleeve is closed around the substrate by closure means which hold together longitudinal edge regions of the sleeve, a sealing member is located internally adjacent the sleeve to extend at least along said edge regions and the sleeve and sealing member are urged together by an urging means situated radially inwardly of the sealing member to effect a seal between said edge regions.
Claim 22
Dependent Claim
30 words
A method according to claim 19, wherein the urging means is compressed by said closure of the sleeve, thereby urging the sealing member and sleeve into contact with one another.
Claim 23
Dependent Claim
