Abstract
Abstract An economical, disposable, flexible, slip or skid resistant, electrically conductive strip device is formed which is useful for temporary attachment to shoes, booties, or the like to provide for the dissipation of static electricity from the bodies of personnel in environments containing explosive or inflammable materials. The strip device comprises a flexible, skid resistant, conductive strip having at one end a footwear-sole-engaging portion provided with pressure sensitive adhesive for attachment to the personnel''s footwear and means at the other end for temporary electrically conductive attachment to the body of the personnel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A Flexible, one-piece elastomeric skid resistant, disposable conductive strip for one-time use for electrically grounding the human body, comprising an elongated strip of flexible, electrically conductive elastomeric material having a foot wearsole-engaging portion at one end thereof provided with pressuresensitive adhesive having a peel adhesion of at least 0.14 kilograms per centimeter of width over at least a portion thereof and a body-contacting portion distally to said foot-engaging portion adapted for temporary attachment to the leg adjacent to said foot wear in electrical contact with the skin and in noninterfering relationship as regards locomotion.
Claim 2
Dependent Claim
94 words
A Flexible, one-piece elastomeric skid resistant, disposable conductive strip for one-time use for electrically grounding the human body, comprising an elongated strip of flexible, electrically conductive elastomeric material having a foot wearsole-engaging portion at one end thereof provided with pressuresensitive adhesive having a peel adhesion of at least 0.14 kilograms per centimeter of width over at least a portion thereof and a body-contacting portion distally to said foot-engaging portion adapted for temporary attachment to the leg adjacent to said foot wear in electrical contact with the skin and in noninterfering relationship as regards locomotion.
Claim 3
Dependent Claim
23 words
The conductive strip of claim 1 having a conductive pressure-sensitive adhesive on the end distal to the pressure-sensitive adhesive on the footwear-sole-engaging portion.
Claim 4
Dependent Claim
20 words
The conductive strip of claim 1 where said conductive strip comprises an elastomer, a thermoplastic binder, and particulate conductive material.
Claim 5
Dependent Claim
13 words

Claim 6
Dependent Claim
12 words
The conductive strip of claim 3 where said elastomeric material is rubber.
Claim 7
Dependent Claim
41 words
A convolutely wound roll of material suitable for being cut into flexible, elongated, conductive strips comprising a sheet of flexible elastomeric, electrically-conductive material having on a portion thereof a strip of pressure-sensitive adhesive, and a release liner surfacing said pressure-sensitive adhesive.
Claim 8
Dependent Claim
41 words
A convolutely wound roll of material suitable for being cut into flexible, elongated, conductive strips comprising a sheet of flexible elastomeric, electrically-conductive material having on a portion thereof a strip of pressure-sensitive adhesive, and a release liner surfacing said pressure-sensitive adhesive.
Claim 9
Dependent Claim
28 words
The material of claim 6 having in addition an electrically-conductive pressure-sensitive adhesive protected by a release liner on a portion of the sheet distal to the pressure-sensitive adhesive.
Claim 10
Dependent Claim
20 words
The material of claim 7 where said conductive sheet comprises an elastomer, a thermoplastic binder, and a particulate conductive material.
