A process and an apparatus for the production of a polyurethane mixture is described. The apparatus comprises a high-pressure mixing device provided with a mixing chamber opening onto a side of a discharge duct.An elongated cleaning member is reciprocable inside the duct and is provided with a longitudinal channel for feeding a fluidized reinforcing material, for example reinforcing fibers or a reinforcing material in powder or granulate form, to be blended with the polyurethane mixture flowing into the discharge duct. The feeding channel for the reinforcing material terminates at the front end of the cleaning member, at a point where the flow of reinforcing material impinges the polyurethane mixture which emerges from the mixing chamber under high turbulence conditions. Blowing nozzles are provided to generate air jets for repeatedly deviating the flow of blended polyurethane mixture and reinforcing material flowing out from the discharge duct.       Recently Added Patents Phenanthroindolizidine analogues Cooccurrence dictionary creating system, scoring system, cooccurrence dictionary creating method, scoring method, and program thereof Stand device Liquid-conducting electrical household appliance Beacon requests and RS bit resolving circular routes Field effect transistor and method of manufacturing the same Three-dimensional image processing apparatus and method of controlling the same   Randomly Featured Patents System and method for employing digital postage marks as part of value-added services in a mailing system Method of forming a saddle tree mold Bracket for flashlight Flotation separation system Fastener grip length selector N-aryl pyrrolidine derivatives as beta-secretase inhibitors Method for manufacturing stacked dynamic random access memories using reduced photoresist masking steps Method of reversing carboplatin resistance by inhibition of HGFIN Method of and apparatus for predicting DC coefficient of video data unit Vertical diverter assembly © 2006-2008 PatentGenius.
