Abstract: A method for transporting particulates wherein the particulates are entrained in a transport air stream. An energizing air stream is introduced into the pipeline to form an air encasement stream between the inner wall of the pipeline and the transport air stream. The air encasement stream is introduced into the pipeline opposite directions to form a forward leaning movement of encasement air at a higher velocity than the transport air.

Abstract: A synthetic clay court composition is provided having a first aggregate-containing elastomeric lamina applied to a substrate. Prior to the elastomer curing aggregate is broadcast over the elastomer in an amount sufficient to form a second free-flowing lamina.
