The invention relates to surfactant systems for liquid aqueous or aqueous-organic formulations comprising a mixture of one or more basic cosurfactants and one or more surfactants from the group of the acidic phosphoric esters. More particularly, an engine responsible for fetching native instructions from a memory subsystem is interfaced with an engine that processes emulated instructions. A plurality of spaced, parallel rods of similar length are positioned near the peripheries of the plates and secured and extending between the plates. An analyzer sends an alert signal to alert the operator if a detected angular shift of one or more reference points of the representation exceeds at feast one of a displacement threshold and a motion threshold. An abrasive product is provided by coating at least the raised areas of the backing with an abrasive coating. At least one cam has a stop wall that closes the respective spindle hole to form a closed non-circular hole.
