    Abstract: In a stirring device of liquid material, of circulation type comprising a return pipe inserted in a stirring tank, and a feeding pipe connected to bottom portion of the stirring tank, so that the liquid material fed through the feeding pipe is returned to the return pipe, an expanded part having inner diameter larger than that of the return pipe is provided at top end of the return pipe, and plurality of holes having the total opening diameter larger than the lateral sectional area of the return pipe are bored on both sides of outer circumferential portion of the expanded part. Two reverse circulation streams in the horizontal direction are formed within the circulation tank, and the liquid material is circulated through the feeding pipe and the return pipe, thereby the stirring is performed well without involving the excessive air.

    Abstract: A method and apparatus for rapidly dispersing particles of dry, water soluble polymer into water wherein air, water and said polymer particles are introduced to a chamber for thorough contact of the polymer with the water to form a mixture of aqueous polymer dispersion and entrained air. The mixture is immediately subjected to shear forces to separate any agglomerated particles into individual particles, and to prevent further agglomeration.

    Abstract: The present invention relates to a continuous manufacturing process for a rubber masterbatch and a rubber masterbatch prepared therefrom. The manufacturing process comprises the following steps: step 1): a filler is added to a rubber solution, forming a rubber/filler/solvent mixture by stirring; and step 2): the solvent is removed and the mixture is dried, resulting in a rubber/filler masterbatch. The present invention also relates to a masterbatch prepared by the above-mentioned process and a rubber article prepared using the masterbatch. Compared to the wet mixing technologies in the prior art, the present invention has no specific requirements of rubber and filler, with a wider scope of usage. In addition, the filler has a high dispersion in rubber compounds, the production process thereof is continuous, highly efficient, low in energy consumption and labour, and thus low in cost.

    Abstract: A vacuum-forming system for deforming a forming blank is disclosed. The system includes a tool and at least one regulator bag disposed adjacent to the tool. The regulator bag includes a sealed bag having an exterior and an interior and a first volume and a defined passage from the interior to the exterior of the regulator bag. The passage is configured such that the regulator bag has a rate of deflation wherein the sealed bag will deflate from the first volume to a second volume over a determined period of time while the exterior of the sealed bag is at a determined reduced pressure. The system also includes a vacuum membrane coupled to the tool, the membrane configured to form a vacuum space enclosing the forming blank and the at least one regulator bag.
