Abstract
Abstract A braid, consisting of monofilaments, made of two different resins which are adapted, when heated, to fuse and mix and be subjected to polymerization or cross-linking. The braid is interposed between a thermo-retractible sleeve and conductors which are to be covered by the sleeve.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A device, for interposing between electrically conductive means and a thermo-retractible protective element disposed about said electrically conductive means, to effect electrically-insulating fluid-tight connection between said thermo-retractible protective element and said electrically conductive means, said device comprising a portion of a fabric having first and second inter-engaged threads, said first and second threads each being constituted of a respective fusible synthetic resinous material which is different from that of the other of said threads, the synthetic resinous material of which said first thread is constituted being selected to undergo polymerisation or cross-linking upon the application of heating by interaction with the material of which said second thread is constituted.
Claim 2
Independent Claim
109 words
A device, for interposing between electrically conductive means and a thermo-retractible protective element disposed about said electrically conductive means, to effect electrically-insulating fluid-tight connection between said thermo-retractible protective element and said electrically conductive means, said device comprising a portion of a fabric having first and second inter-engaged threads, said first and second threads each being constituted of a respective fusible synthetic resinous material which is different from that of the other of said threads, the synthetic resinous material of which said first thread is constituted being selected to undergo polymerisation or cross-linking upon the application of heating by interaction with the material of which said second thread is constituted.
Claim 3
Dependent Claim
25 words
A device, as claimed in claim 1, wherein the synthetic resinous material of said second thread constitutes a catalyst for the said polymerisation or cross-linking.
Claim 4
Dependent Claim
27 words
A device, as claimed in claim 1 wherein the synthetic resinous material of which said second thread is constituted includes a catalyst for the polymerisation or cross-linking.
Claim 5
Dependent Claim
15 words
A device, as claimed in claim 1, wherein said first and second threads are braided.
Claim 6
Dependent Claim
15 words
A device, as claimed in claim 1, wherein said first and second threads are knitted.
Claim 7
Dependent Claim
15 words
A device, as claimed in claim 1, wherein said first and second threads are woven.
Claim 8
Dependent Claim
13 words
A device, as claimed in claim 1, in the form of a sleeve.
Claim 9
Dependent Claim
15 words
A device, as claimed in claim 1, wherein said first and second threads are monofilaments.
Claim 10
Dependent Claim
23 words
A device, as claimed in claim 1, wherein said first thread is of epoxy resin and said second thread is of polyamide resin.
Claim 11
Dependent Claim
31 words
A device, as claimed in claim 1, wherein said first thread is of polyester resin and said second thread is of a mixture of ethylene vinyl acetate resin and polyurethane resin.
Claim 12
Dependent Claim
147 words
In combination, for the production of an electrically-insulating fluid-tight protective covering about an electrically-conducting means: (i) a protective sheath for placing about said electrically-conducting means, said sheath being made of a material selected, upon the application of heating at a predetermined temperature, to be thermo-retractible, and (ii) a sleeve for interpositioning between said sheath and said electrically-conducting means, said sleeve being of a fabric having first and second interengaged threads, said first and second threads each being constituted of a respective fusible synthetic resinous material which is different from that of the other of said threads, the synthetic resinous material of which said first thread is constituted being selected to undergo polymerisation or cross-linking upon the application of heating at said predetermined temperature and in the presence of a catalyst, the synthetic resinous material of which said second thread is constituted being selected to provide said catalyst.
Claim 13
Dependent Claim
147 words

Claim 14
Dependent Claim
85 words
In an assembly comprising a portion of each of two electrically conductive elements and an electrically-conductive joint formed between said portions, the improvement which comprises an electrically-insulating fluid-tight protective covering formed about said assembly, said covering being the resultant of applying heating at a predetermined temperature to a protective sheath and sleeve as set forth in claim 11, said sheath and said sleeve being disposed about said portion and said joint, and said sleeve being interposed between said sheath and said portions and said joint.
Claim 15
Dependent Claim
34 words
A device as claimed in claim 1, wherein the synthetic resinous material of which said second thread is constituted polymerises or cross-links with the synthetic resinous material of which said first thread is constituted.
