A mixer having a discharge screw centrally located between first and second side walls and disposed in a cavity provided in the bottom. The discharge screw has (a) a shaft with a first end that extends through a first end wall and (b) a driven end opposite the first end of the shaft, with the driven end being connected to a motor shaft for rotating the discharge screw in at least one direction. The driven end has a recessed portion that extends into the second end wall of the vessel. The mixer may include a deflector that is fixed to the second end wall and extends toward the first end wall and is located between the mixing blades and the discharge screw.

A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.

Pellet-stable olefinic copolymer bimodal rubber is made using parallel reactors, with one reactor synthesizing higher molecular weight (MW) rubber with dual catalysts, with an improved molecular weight split ratio and an improved composition distribution of the moderate and ultra-high MW components, while another reactor synthesizes random isotactic polypropylene copolymer (RCP). The effluents are reactor-blended and result in pellet-stable bimodal rubber (P-SBR), which may be pelletized. When making thermoplastic vulcanizates (TPVs) with P-SBR, the need to granulate rubber bales and subsequently use talc, clay, or other anti-agglomeration agents to prevent granulated rubber crumbs from agglomerating are eliminated. TPVs made with P-SBR have vulcanized rubber particles that are smaller and more uniform in size, resulting in TPVs with higher particle counts and more thermoplastic “ligaments” between the particles, with such ligaments being made stronger by the added RCP. Such thus-produced TPVs have a lower hysteresis and flexural modulus, and better elastic properties.

A process for producing tyres including building a green tyre having two bead structures. Each bead structure includes a bead filler. The bead filler or another rigid component of the green tyre includes a final elastomeric compound produced by the following: feeding elastomeric polymer and reinforcement filler to a first batch mixing device; mixing and dispersing the reinforcement filler in the elastomeric polymer and unloading the obtained elastomeric compound; feeding the obtained elastomeric compound, along with at least 5 phr of reinforcement resin, to a continuous mixing device of intermeshing and co-rotating twin-screw or multi-screw type or of planetary type; mixing the reinforcement resin in the elastomeric compound and unloading the obtained elastomeric compound; and feeding the obtained elastomeric compound along with the components capable of facilitating the cross-linking to a second batch mixing device and mixing to obtain the final elastomeric compound. The first and second batch mixing device have two counterrotating rotors.
