Abstract: A plastic molded deck board provides a sturdy, durable, lightweight, economical, readily identifiable, and easily handled surface for supporting cargo on top of trailer load beams. The deck board defines a platform having a top face for supporting cargo, a bottom face and a plurality of side faces. The top face defines a plurality of protrusions having variable shapes and heights and rubber stoppers for providing surface friction. The bottom face defines a plurality of side walls, a plurality of angled cross walls, a first platform channel and optionally a second platform channel disposed between the plurality of angled cross walls for receiving a center load beam of a cargo trailer. The top face defines recessed slots for receiving the angled cross walls of another deck board such that two or more deck boards can be securely stacked.

Abstract: This invention discloses a rubbery polymer which is comprised of repeat units that are derived from (1) at least one conjugated diolefin monomer, and (2) at least one leaving group-bearing monomer having the structural formula: wherein R represents an alkyl group containing from 1 to about 10 carbon atoms or a hydrogen atom, wherein R? represents a methyl group or a hydrogen atom, with the proviso that if R represents an alkyl group then R? represents a hydrogen atom, and wherein R1 and R2 can be the same or different, wherein R1 represents an alkyl group that is functionalized with a leaving group, wherein R2 represents a moiety selected from the group consisting of hydrogen atoms, alkyl groups containing from 1 to 18 carbon atoms, aryl groups containing from 6 to 18 carbon atoms, alkaryl groups containing from 7 to 18 carbon atoms, and alkyl groups that are functionalized with a leaving group.

Abstract: The invention is directed to an oil extended rubber and composition comprising: a solution-polymerized elastomer derived from at least one conjugated diene monomer and at least one vinyl aromatic monomer, the elastomer coupled with at least one metal selected from the group consisting of silicon and tin; and from about 5 to about 70 parts by weight, per 100 parts by weight of elastomer (phr), of a process oil having a glass transition temperature of from about ?80° C. to about ?40° C., a polycyclic aromatic content of less than 3 percent by weight as determined by the IP346 method, and an aromatic content of less than 20 percent by weight as measured by ASTM D2140.

Abstract: A deployment apparatus for a flexible cover sized to cover a side-dump container comprises first and second swing arm assemblies pivotally mounted at a pivot point to opposite sides of the container. A drive assembly connected to the roll tube of the flexible cover is operable to rotate the roll tube so that the flexible cover winds around the roll tube. The drive assembly is slidably supported on one of the swing arms so that the mechanism translates along the length of the swing arm as it winds the flexible cover around the roll tube. A stop is provided on the swing arm between the pivot point and the free end to limit the translation of the drive assembly along swing arm. In another form, the drive assembly is fixed to a swing arm that is slidably received in a pivoting spring mechanism.

Abstract: The invention is directed to an oil extended rubber and composition comprising: a solution polymerized elastomer derived from isoprene and optionally at least member of the group consisting of conjugated dienes and vinyl aromatic monomers; and from about 5 to about 70 parts by weight, per 100 parts by weight of elastomer (phr), of a process oil having a glass transition temperature of from about ?80° C. to about ?40° C. and a polycyclic aromatic content of less than 3 percent by weight as determined by the IP346 method.
