摘要： A pneumatic tire includes a low conductive rubber portion forming at least a cap rubber portion of the tread rubber which provides a tread surface of the tire. A narrow high conductive rubber strip extends in a radial direction of the tire at a widthwise center region of the cap rubber portion, and is exposed to the tread surface to form a discharge path for allowing electrostatic charges of a vehicle body to be discharged to a road surface. An unvulcanized tread rubber for the tire is obtained by passing a high conductive unvulcanized rubber through a passage extending from an extruder unit to the back side of an extrusion orifice, to form at least part of the remaining potion of the tread rubber. The high conductive unvulcanized rubber while passing through the passage is partly introduced into a narrow branch passage and passed through a slit-like opening having a cross-sectional shape which is substantially straight in a height direction of the extrusion head and situated in the vicinity of the back side of the extrusion orifice, to form the narrow strip of the high conductive rubber in a composite body of different kinds of unvulcanized rubbers.

摘要： A multiple-orifice extrusion manifold 10 is disclosed which includes a first housing 20 defining an outer chamber 170 and an extrusion wall 140. A plurality of orifices 80, adapted for extruding a first substance from the outer chamber 170, extend through the extrusion wall 140. An inlet pipe 40 is provided in the first housing 20 for flowing the first substance into the outer chamber 170. The inlet pipe 40 is located so as to permit flow of the first substance symmetrically within the outer chamber 170. A second housing 190 which defines an inner chamber 200 is provided within the first housing 20. The second housing 190 is located symmetrically within the outer chamber. A plurality of tubes 210 extend from the second housing 190. Each tube 210 has a first end 212 opening into the inner chamber 200 and a second open end 213 cooperatively aligned with an orifice 80 for extruding a second substance from the inner chamber 200 through the tube 210 and to within the first substance. Thus, each extrudate substance is flowed to an extrusion orifice 80 through a flow path, which is symmetrical with all other flow paths for that substance. The manifold housing 20 presents a right circular cylindrical outer surface 70 with the extrusion orifices 80 therein. The orifices 80 are equally spaced around the outer surface 70. Three blades 110 with a cylindrically rotating path about the cylindrical outer surface 70 are provided to cut a continuous extrusion at each orifice as the blade or blades pass the orifice. The blades 110 are mounted for rotation around the inlet pipe 40 which supplies an extrudable substance to the housing.

摘要： A container capable of containing components of a mixture in chambers separated by a peelable seal constructed from a multi-layer film. The multi-layer film has at least one layer of a RF-responsive material and an interior layer of non-RF responsive material. When the layers are subjected to RF energy, the RF-responsive layer heats the interior layers resulting in a bond in the form of a peelable seal between the interior layers. The peelable seal is capable of withstanding external pressures to the container, such as from dropping the container. The seal may be selectively opened to allow mixture of components contained therein.

摘要： The present invention discloses an extrusion die module having a flat compression seal surrounded by a conical or otherwise angled spillover surface. The die module promotes a flat surface to flat surface compression seal outside of the flow distribution channels and promotes better streamlined flow and material combination than a traditional flat disk die module. The die module promotes a reduced overall diameter and wetted diameter in comparison to standard flat disk dies. In addition, the present invention relates to an extrusion die module having a spillover surface surrounding a planar sealing surface. Further, the present invention relates to a method for utilizing an extrusion die module with a conical or otherwise angled spillover surface to minimize the die surface area wetted by an intermediate layer in a multi-layer coextrusion process.
