Abstract: The invention relates to a load-compensating rope sheave arrangement for drum winders, comprising at least two rope sheaves which are vertically guided in sliding frames and mounted on hydraulically short-circuited cylinders. Multiply redundant monitoring of the different sheave loads acting upon the rope sheaves is carried out via the hydraulic cylinders which are connected to the system control of the drum winder for communication.

Abstract: A method for inhibiting agglomeration of a block copolymer is presented, the method including coupling a plurality of block copolymer segments with a degradable coupling agent and thereafter drying the coupled block copolymer.

Abstract: A modified asphalt composition comprising a naphthenic asphalt, and a high-vinyl block copolymer is presented. The modified asphalt composition is prepared by combining a naphthenic asphalt and a high-vinyl block copolymer. Further an asphalt concrete is presented, such concrete comprises an asphalt, a functionalized block copolymer, and a siliceous aggregate. A diblock copolymer is presented, such copolymer comprises a vinyl block comprising conjugated vinyl aromatic units, a diene block comprising conjugated diene units and substantially devoid of a tapered block section between the vinyl block and the diene block wherein the diblock copolymer comprises a vinyl content of at least about 20%, and a molecular weight of at least about 50,000.

Abstract: The inventive composition includes a block copolymer which includes four blocks and has the following block arrangement: B-S-B-S. The two polymer blocks B comprise conjugated diene monomer constitutional units; and the two polymer blocks S comprise vinyl aromatic hydrocarbon monomer constitutional units. The invention also includes methods of making such inventive compositions as well as asphalt compositions and/or thermoplastic elastomers which include such block copolymer.
