  • Publication number: 20230380478
    Abstract: An assembly to facilitate removal of a susceptor heating element from an aerosol generating article includes a cutting tool comprising (i) a body defining a passageway through which the aerosol generating article may be passed, and (ii) a cutting element extending into the passageway. The cutting element comprises a cutting edge arranged to cut the aerosol generating article as the aerosol generating article passes through the passageway. The assembly may include a heating element removal tool comprising a tip configured to magnetically attract the susceptor heating element. Alternatively, the cutting element may comprise a magnet to attract the susceptor heating element as the aerosol generating article passes the cutting element as the aerosol generating article passes through the passageway.

  • Patent number: 10913804
    Abstract: The present invention relates to a process for separating natural rubber deriving from non-Hevea type plants, in the form of solid crumbs, from solutions in an organic solvent system including it, where said organic solvent system may comprise at least one nonpolar organic solvent, or a mixture of at least one nonpolar organic solvent and at least one polar organic solvent, and the concomitant removal of said organic solvent system from said rubber, where the aforementioned process comprises subjecting said solution to a stripping stage by means of water vapor, in presence of a dispersing system, separating the aforementioned crumbs of natural rubber from the liquid phase, obtained through the stripping stage, and subjecting said crumbs to drying.

  • Patent number: 9090746
    Abstract: A process for the removal of solvent from a polymeric solution including at least one elastomeric polymer. The polymeric solution is subjected to a stripping step by means of water vapor, in the presence of a dispersant system including: from 0.005% by weight to 1% by weight, with respect to the total weight of the dry elastomeric polymer, of at least one lamellar material; from 0.0005% by weight to 1% by weight, with respect to the total weight of the dry elastomeric polymer, of at least one cationic surfactant.

  • Publication number: 20140323674
    Abstract: A process for the removal of the solvent from a polymeric solution including at least one elastomeric polymer, which comprises subjecting said polymeric solution to a stripping step by means of water vapour, in the presence of a dispersant system comprising: —from 0.005% by weight to 1% by weight, preferably from 0.008% by weight to 0.8% by weight, with respect to the total weight of the dry elastomeric polymer, of at least one lamellar material; —from 0.0005% by weight to 1% by weight, preferably from 0.0008% by weight to 0.8% by weight, with respect to the total weight of the dry elastomeric polymer, of at least one cationic surfactant.
