Abstract: The within invention is directed at a composite material comprising a product of a combination of materials. The combination of materials comprises an organic filler comprised of cellulosic material, a thermoplastic polymer having a melt temperature of less than the char temperature of the organic filler and a coupling agent comprised of at least one fatty acid having at least 16 carbon atoms and at least one rosin acid having at least 16 carbon atoms. The within invention is further directed at a process for producing the composite material comprising the step of combining the organic filler, the thermoplastic polymer and the coupling agent at a temperature of greater than or equal to the melt temperature of the thermoplastic polymer and less than the char temperature of the organic filler.

Abstract: The invention is directed at a composite material comprising a product of a combination of materials. The combination of materials comprises an inorganic filler comprised of ceramic cenospheres, a thermoplastic polymer and a coupling agent comprised of at least one fatty acid having at least 16 carbon atoms and at least one rosin acid having at least 16 carbon atoms. The combination may further comprise an organic filler comprised of cellulosic material and wherein the thermoplastic polymer has a melt temperature of less than the char temperature of the organic filler. The invention is further directed at a process for producing the composite material comprising the step of combining the components at a temperature of greater than or equal to the melt temperature of the thermoplastic polymer. Where the components include the organic filler, the process temperature is less than the char temperature of the organic filler.

Abstract: Removal of particulate solids and water from petroleum crudes to bring the BS&W content of the crude within pipeline specifications is accomplished with the aid of a demulsifier comprising an anionic surfactant soluble in oil, a nonionic surfactant insoluble in water and dispersible in oil, and a cationic surfactant soluble in water, the anionic surfactant being in a major proportion, the nonionic and cationic surfactant being in lesser proportions.

Abstract: Petroleum crudes, particularly heavy oil crudes produced by thermal or other enhanced recovery procedures, are treated to break the water-in-oil emulsion and reduce the BS&W content by use of additives, advantageously ammonium bisulfite, which act upon inorganic sulfur contained in the crude.

Abstract: Particulate solids and water are removed from petroleum crude to bring the BS&W content of the crude within pipeline specifications by treating a blended and dewatered crude to destabilize the water-in-oil emulsion of the crude and providing in uniform distribution through the treated crude both produced water and an acid-reacting coagulating agent while maintaining the crude at a pH of at least 8, then maintaining the resulting treated crude at 52.degree.-88.degree. C. for at least a few minutes, separating the treated crude into at least an oil phase and a water phase, and recovering the oil phase as a clean blended crude oil having a BS&W content within pipeline specifications and in a yield significantly greater than that which can be recovered without use of produced water and coagulating agent.

Abstract: A method for belling the ends of thermoplastic pipes including the steps of delivering the pipes successively to an initial location adjacent conveyor means including a continuously driven endless belt, and transferring the pipes successively from the initial location onto the conveyor means in a spaced relationship with each pipe disposed for movement by the conveyor means in a direction transverse to the length of the pipe and in a spaced relationship through heating and belling stations.

Abstract: Marker posts, useful for delineating traffic paths, e.g., on highways, airports and parking areas, capable of being impacted and run over by vehicles at sub-zero ambient temperatures, with the post returning to its normal upright position. The posts are extruded tubular bodies of polyethylene modified by an additional polymer selected from the group consisting of ethylene-vinyl acetate copolymers and ethylene-ethyl acrylate copolymers.

Abstract: Method and apparatus for belling an end of a length of thermoplastic pipe by thermally softening the end of the pipe, inserting an expansible belling head into the softened end, expanding the belling head to accomplish shaping of the thermoplastic material, cooling the pipe, and then separating the pipe from the belling head.
