Abstract: A method for forming a polymer-filler composite having advantageous bound filler content, the method comprising (a) providing a guayule cement; (b) introducing particulate filler to the guayule cement to form a solution masterbatch; and (c) desolventizing the solution masterbatch to form a polymer-filler composite.

Abstract: Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

Abstract: In various embodiments, methods for producing aqueous polyisoprene latex from natural cis-1,4-polyisoprene are described. The natural cis-1,4-polyisoprene may be sourced from guayule scrubs. In various embodiments, the method comprises extracting guayule plant material to form a miscella, fractionating the miscella to a preliminary cement, diluting the preliminary cement to a cement for dispersing, dispersing the cement in an aqueous surfactant mixture under high shear to produce an emulsion, and de-solventizing the emulsion to produce an aqueous latex dispersion. The rubber solids level can then be adjusted by centrifugation and dilution in water to produce a final aqueous cis-1,4-polyisoprene latex.

Abstract: An extractor suitable for using a solvent to separate a compound from a solid or semisolid substance containing the compound. The extractor includes a conveying assembly having an inclined conveyor for receiving the substance from a substance inlet and moving the substance through the solvent, an inclined upper surface associated with the first conveyor and an inclined lower surface associated with the first conveyor. The conveyor is configured to move the substance downward through the solvent along the upper surface toward a lower end of the conveyor and upward through the solvent along the lower surface toward an upper end of the conveyor.

Abstract: Methods, systems, and computer program products sustain a fleet of configuration-controlled assets. The method involves integrating a plurality of previously separate systems with reusable business transactions associated with managing a fleet of vehicles. The method also involves receiving operational data associated with a vehicle of the fleet, integrating the operational data per customer requirements, packaging and distributing the operational data to the plurality of systems, and installing and distributing the operational data to one or more applications of the plurality of systems utilizing reusable business transactions. The system utilizes a plurality of applications and a plurality of logical subsystems, which are connected to each other through gateways. The logical subsystems use a common format defined by a set of messages. However, the applications can use a plurality of different formats.
