    摘要: One exemplary embodiment includes a product including a housing that has a mixer portion and first, second and third openings. The first opening is configured to receive at least a portion of exhaust gases produced by an internal combustion engine, and the second opening is configured to receive intake air. The mixer portion is in communication with the first and second openings to mix the exhaust gases and the intake air into a gas mixture. The third opening is in communication with the mixer portion to flow the gas mixture therethrough. The invention further includes a particulate separator disposed within the housing. The particulate separator is configured to remove particulates from the exhaust gases. The product may be included in a low-pressure EGR path and/or a high-pressure EGR path.

    摘要: The present invention relates to a process for the preparation of aqueous dispersions or solutions of polyurethanes which have urea end groups and contain non-ionic hydrophilic segments and which are capable of being cross-linked with the aid of cross-linking agents which are reactive with urea groups, characterized in that prepolymers which have isocyanurate end groups and which(i) have an average molecular weight of less than about 15,000 and(ii) contain from about 2 to 30%, by weight, of ethylene oxide units corresponding to the following formula:--CH.sub.2 --CH.sub.2 --O-- within a polyether chain (containing ethylene oxide units)are reacted at from about 10.degree. to 70.degree. C. with an aqueous solution of ammonia or with a primary amine, optionally dissolved in water, the aqueous solution of ammonia or the primary amine, optionally dissolved in water, being added to the prepolymer in the reaction vessel and the quantity of water used for dissolving the ammonia or primary amine being not more than about 10%, by weight, based on the total quantity of reaction mixture, and finally, after termination of the addition reaction between the free isocyanate groups of the prepolymer and the added ammonia or primary amine, the reaction product obtained is stirred with water at from about 10.degree. to 70.degree. C. to form an aqueous dispersion or solution having a concentration of from about 5 to 65%, by weight. The present invention also relates to the use of dispersions or solutions obtainable by the process according to the present invention for the production of cross-linked sheets by application of the dispersion to a substrate and drying, cross-linking of the sheet being ensured by the addition of a cross-linking agent capable of undergoing a cross-linking reaction with the urea groups either before, during or after application of the solution or dispersion to the substrate.

    摘要: A process for preparing modified aqueous synthetic resin dispersions, comprising introducing organic diisocyanates which are liquid at room temperature into polyurethane-containing, non-sedimenting, aqueous synthetic resin dispersions, optionally in the presence of catalysts which accelerate the isocyanate polyaddition reaction and/or the dimerization of isocyanate groups and/or the carbodiimidization of isocyanate groups and/or the trimerization of isocyanate groups, mixing the organic diisocyanate with the aqueous dispersion at a temperature at which no visible foaming occurs, maintaining the temperature after addition of all the diisocyanate until at least 50% of the isocyanate groups in the added diisocyanate have undergone reaction and, if desired, completing the reaction by subsequently heating to temperatures up to 100.degree. C.These modified aqueous dispersions contain dispersed latex particles which are enveloped with polyurea formed from the diisocyanates. These modified dispersions are useful as water-resistant surface coatings and leather dressings which are abrasion resistant in the wet.
