Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
57 words
An article capable of screening an electrical component, which comprises: (a) a recoverable fabric having as a component thereof fibres comprising an electrically conductive material; and (b) means for electrically terminating said fibres, said article after recovery having a surface transfer impedance of 5 ohm/m or less, measured over a frequency of from 1 to 50 MHz.
Claim 2
Dependent Claim
57 words
An article capable of screening an electrical component, which comprises: (a) a recoverable fabric having as a component thereof fibres comprising an electrically conductive material; and (b) means for electrically terminating said fibres, said article after recovery having a surface transfer impedance of 5 ohm/m or less, measured over a frequency of from 1 to 50 MHz.
Claim 3
Dependent Claim
17 words
An article according to claim 1, in which said surface transfer impedance is 40 mohm/m or less.
Claim 4
Dependent Claim
31 words
An article according to claim 1, in which the fabric comprises a weave, the weft of which comprises the recoverable fibres and the warp comprises the fibre comprising the conductive material.
Claim 5
Dependent Claim
25 words
An article according to claim 1, in which the fabric comprises a warp or weft inserted knit, recoverable by virtue of a recoverable fiber insertion.
Claim 6
Dependent Claim
24 words
An article according to claim 1, in which the optical coverage of the fabric by the conductive material after recovery is at least 70%.
Claim 7
Dependent Claim
17 words
An article according to claim 1, wherein the article is in the form of a wrap-around sleeve.
Claim 8
Dependent Claim
29 words
An article according to claim 1, in which the means for electrically terminating comprises a mechanical clamp which has an electrically conductive surface in contact with said conductive material.
Claim 9
Dependent Claim
30 words
An article according to claim 1, in which the means for terminating comprises a recoverable driver member, exhibiting a recovery force per unit area greater than that of said fabric.
Claim 10
Dependent Claim
18 words
An article according to claim 1, in which the means for terminating comprises an electrically conductive sealing material.
Claim 11
Dependent Claim
20 words
An article according to claim 9 in which said sealing material comprises a solder, heat-softenable sealant or a hot-melt adhesive.
Claim 12
Dependent Claim
37 words
An article according to claim 9, in which the sealing material is heat-activatable and the fabric is heat-recoverable, the activation temperature of the sealing material differing from the recovery temperature of the fabric by 20° or less.
Claim 13
Dependent Claim
17 words
An article according to claim 1, in which said means for terminating is attached to the fabric.
Claim 14
Dependent Claim
18 words
An article according to claim 12 in which said means for terminating comprises solder fibres in the fabric.
Claim 15
Dependent Claim
23 words
An article according to claim 1, in which the fabric additionally comprises a laminate of a polymeric material, thereby rendering the fabric impervious.
