The second layer with its insert is extruded from a main extruder for the extrusion of the portion of a tread in the unvulcanized condition, and a micro-extruder whose extrusion nozzle is fitted with a cutting edge and whose extrusion orifice is directed against a conveyor associated with the main extruder.Type: GrantFiled: August 24, 2000Date of Patent: December 28, 2004Assignee: Compagnie Generle des Etablissements Michelin-Michelin & CieInventors: Didier Calvar, Serge Nicolas, Daniel Bardy

Patent number: 6793858Abstract: A method and apparatus for continuously forming flexible mat structure in the form of spaced, interconnected concrete panels. The mat structure can serve as an erosion control mat along the banks of waterways and within drainage ditches and channels, and can also be utilized to provide temporary or permanent walkways and roadways. A rotatable drum includes peripherally-positioned mold cavities that receive concrete mix from a trough supplied from a source of concrete mix. A grid is fed against the drum periphery and over the mold cavities before the concrete mix is introduced, and after the mix is introduced a web of fibrous material is brought into contact with the concrete-mix-containing mold cavities to overlie the concrete-containing surface of the drum. As the drum rotates the fibrous material with overlying, interconnected concrete panels is deposited on the ground to provide the a finished mat structure.Type: GrantFiled: May 31, 2001Date of Patent: September 21, 2004Inventor: James G.

Patent number: 6780355Abstract: Diffuse reflective materials proximate to a structure formed by thermally induced phase separation of a thermoplastic polymer and a diluent providing enhanced flexibility and reflectivity especially in the visible wavelengths of 380-730 nanometers are described. Such materials find a wide variety of application among combinations with other reflective layers. The diffuse reflective articles are useful in backlight units of liquid crystal displays, lights, copy machines, projection system displays, facsimile apparatus, electronic blackboards, diffuse white standards, photographic lights and the like.Type: GrantFiled: October 17, 2002Date of Patent: August 24, 2004Assignee: 3M Innovative Properties CompanyInventors: Wade D Kretman, Scott R Kaytor

Patent number: 6740276Abstract: A process of making a pigmented shaped article comprising: (a) providing polytrimethylene terephthalate chips and two or more colored pigmented chips each containing at least one different color pigment; (b) heating the polytrimethylene terephthalate chips and colored pigmented chips to a temperature of about 200-about 280° C. to melt the chips and form a polymer composition comprising the polytrimethylene terephthalate and at least one color pigment; and (c) forming a shaped article from the polymer composition.Type: GrantFiled: June 29, 2001Date of Patent: May 25, 2004Assignee: E. I. du Pont de Nemours and CompanyInventors: Nirmal K. Agarwal, Jing C. Chang, Richard Lee Dommel, Joseph V. Kurian, Raymond Longhi

Patent number: 6706413Abstract: The present invention is a non-porous, breathable membrane of at least polyamide-4,6, with an elongation at rupture of about 250 to about 500% in the longitudinal direction and about 200 to about 500% in the transverse direction. The membrane has a higher heat resistance than a non-porous, breathable membrane made from polyether ester and, if it also contains an antioxidant, passes the oven/watertightness test. If the membrane is produced from a mixture of polyamide-4,6 and about 10 to about 30% by weight polyether amide, the membrane exhibits a surprisingly increased water-vapor permeability. The membrane is usable in the manufacture of thermally protective clothing.Type: GrantFiled: April 3, 2002Date of Patent: March 16, 2004Assignee: Sympatex Technologies GmbHInventors: Bertram R. Böhringer, Henricus Joannes Maria Van De Ven, Jozef Christiaan Wilhelmus Spijkers
