    Abstract: A stitched yarn surface structure includes a backing having decorative upper surface and a thickness dimension T of at least two (2) millimeters. The backing exhibits a predetermined compressive resistance Rb. Plural rows of face yarn segments cover at least a portion of the decorative upper surface of the backing, with adjacent face yarn segments being spaced apart by a predetermined minimum spacing dimension S. The yarns forming the face yarn segments have a predetermined compressive resistance Ry. The compressive resistance Rb, the compressive resistance Ry, and the spacing S are selected such that a load of up to one hundred (100) pounds per square inch (psi) imposed on the stitched yarn surface structure by a loading member is able to be borne by the stitched yarn surface structure without allowing contact between the member and the decorative upper surface of the backing.

    Abstract: Apparatus (10) for agitating a cleaning agent into a carpet comprises a housing (16) within which a first and a second roller (76f, 76r) are each mounted for rotation in a first angular direction. A platen (112) is mounted intermediate the rollers (76f, 76r). A belt agitator (134) comprising a fabric substrate (134f) having a pile surface (134p) is trained about the first and second rollers (76f, 76r) and extends under the platen (112). The rollers (76f,76r) and the platen (112) support rectilinear movement of the belt agitator (134) in the first direction (138) to bring a portion (140s) of its surface sequentially from a first position (140a) within the housing (16) to a contacting position (140b) in which the portion of the surface is in agitating contact with a carpet and, thereafter, to a second position (140c) within the housing (16).

    Abstract: This invention concerns a process for the addition of volatile materials like catalysts, stabilizers, plasticizers or comonomers to to prepolymers of e.g. polyesters, polyamides or polycarbonates prior to or during solid state polymerization processes and the subsequent conducting of said solid state polymerization process. In one embodiment a catalyst like toluene sulfonic acid is introduced into the inert gas stream during solid state polymerization of a polyester like polyethylene terephthalate. Alternatively the prepolymer pellets are contacted with a solution of the volatile material before solid state polymerization.
