A surface coil system for single channel MRI reception comprising a coil system including a plurality of self-resonant, overlapping coil conductor sections arranged relative to one another and to anatomical regions of a patient such that a combination of regions form a desired larger region of interest, a control unit located remotely from the coil system and electromagnetically communicating therewith, having means for selectively electronically activating and deactivating each coil section to produce MRI output signals when activated, means for combining selected MRI output signals, and means for electrically connecting the coil system to an MRI system to transmit selected MRI signals to the MRI system.

A thermoplastic elastomer asphalt composition is a blend of 100 parts by weight of asphalt, from about 12 to about 20 parts by weight of ground rubber containing primarily SBR, natural rubber, or polybutadiene, and from about 2 to about 8 parts by weight of a styrene-butadiene block copolymer. A block copolymer has at least two styrene blocks, each having a molecular weight of from about 5,000 to about 20,000 and may be linear or branched. The blend has good low and high temperature cohesive and adhesive properties, good low and high temperature flexibility, and good elasticity. The composition can be used as a crack sealer, a concrete joint sealer filler, an overlay sealant for construction materials, and the like.

A flame retardant synthetic rubber composition for use as a flooring material including a high bound styrene resin polymer and known flooring compounding ingredients. A hot emulsion SBR polymer, antimony oxide, a chlorinated paraffin hydrocarbon and hydrated alumina are present and the composition also includes a high flash point naphthenic oil.
