Abstract
Abstract An article of manufacture is described which, in normal use, tends to accumulate a charge of electricity. Secured to the article is a substrate containing static electric dissipating elements having grid-like discontinuities. As such, it can be used in the manufacture of carpets. The normal propensity of such carpets to accumulate a charge of static electricity is thus greatly reduced.
