Abstract: An improved carpet tile for commercial, industrial or home use is disclosed. The carpet tile includes a tufted carpet facing portion including a stiffening and stabilizing layer (e.g., a primary backing layer and a glass fiber layer) in which the tufted carpet portion is embedded. The backing portion also includes a stiffening and stabilizing layer (e.g., glass fiber layer). Interposed between the facing and backing portions is a resilient thermoplastic material (e.g., polyvinyl chloride). The resulting unitary carpet tile shows surprising dimensional stability, stiffness and floor hugging properties even during periods of concentrated stress.

Abstract: An improved carpet tile for commercial, industrial or home use is disclosed. The carpet tile includes a carpet pile yarn facing portion including a stiffening and stabilizing layer (e.g., glass fiber layer). The backing portion also includes a stiffening and stabilizing layer (e.g., glass fiber layer). Interposed between the facing and backing portions is a stabilizing layer of a mixture of from about 70 to about 90 weight percent non-woven glass fibers and from about 30 to about 10 weight percent of a polyester. The resulting unitary carpet tile shows surprising dimensional stability, stiffness and floor hugging properties even during periods of concentrated stress, and passes rigorous flame retardancy and smoke emission tests.

Abstract: A hydraulic motor for converting the potential energy of a reservoir of water into mechanical or electrical energy and utilizing a reciprocating free floating piston that can be cyclically drained and filled, or floated in a cylinder that can be drained and filled, and including automatically actuated valves to permit the draining and filling, and detention devices for restraining the piston from motion for a portion of its cycle.
