Abstract: The present invention provides a process for the production of a viscoelastic flexible polyurethane foam. The invention further relates to a viscoelastic flexible polyurethane foam slab or viscoelastic flexible polyurethane foam molding with particularly low emission values and pH values as close as possible to neutral, produced by the process according to the invention, and to the use of these foams.

Abstract: Resolving heterogeneous communication collisions in a system includes measuring a quality-of service value for at least one communication connection, determining if a communication collision is reducing the quality-of-service value to below a pre-determined threshold, and, if a communication collision is reducing the quality-of-service value to below a pre-determined threshold, iteratively modifying the at least one communication connection until either a maximum number of iterations has been exceeded or the quality of service value exceeds the pre-determined threshold.

Abstract: Moulded bodies are described which comprise a humus-containing plant substrate consolidated with polyurethane/polyurea, which are obtainable by slurrying a humus-containing plant substrate in water, admixing a liquid NCO prepolymer having a maximum NCO content of 15% by weight which has been produced by the reaction of toluene diisocyanate with a polyether polyol component containing at least one aminopolyether polyol in an amount of 0.5 to 100 mole % with respect to the polyol component, and introducing the mixture thus obtained into a mould and allowing it to solidify. A process for producing these moulded bodies is also described, as is their use as growth media for seedlings in the propagation and raising of plants.

Abstract: A deflection unit for a cathode ray tube, the deflection unit having saddle-shape sets of coils which are wound in slots which extend along the inside of a one-piece coil form. The coil form is flared so as to conform to the outer surface of the envelope of a cathode ray tube. The coils are wound so as to be interleaved in respective slots of the coil form thereby ensuring that the two sets of coils have substantially equal diameters with respect to a central longitudinal axis of the coil form. In further embodiments, apparatus is provided for rotatably affixing the deflection unit to the cathode ray tube so as to permit rotation of the cathode ray tube image. Such rotation may be achieved by an electric motor.

Abstract: The instant invention is directed to a process for the production of a cellular polyurethane elastomer having a density of 0.45 to 0.8 g/cm.sup.3, comprising:(a) preparing a prepolymer having an isocyanate content of 10 to 25% by weight from aromatic polyisocyanates and a portion of one or more polyhydroxyl compounds having a molecular weight of from 400 to 6,000; and(b) reacting said prepolymer with the remainder of said polyhydroxyl compound and water;wherein the quantity of said water is 0.3 to 1% by weight and the equivalent ratio of isocyanate groups to isocyanate reactive compounds is in the range of 0.95:1 to 1.1:1, characterized in that from 0.1 to 0.8% by weight, based on the whole reaction mixture, of aromatic diprimary diamines having a molecular weight from 108 to 500 are also used in (a) or (b).
