  • Patent number: 6139675
    Abstract: Disclosed is a process of manufacturing a water-based adhesive bonded, solvent resistant protective laminate utilizing the steps of: providing a film having a first surface and a second surface; depositing a discontinuous coating of a cross-linkable; carboxylated styrene-butadiene rubber latex adhesive on the first surface of the film, the latex adhesive containing an effective amount of a cross-linking agent; joining a fibrous nonwoven web into intimate bonding contact with the film and adhesive; and removing water from the adhesive thereby causing cross-linking at reactive sites. The adhesive may be deposited utilizing gravure printing techniques and is desirably deposited at a rate greater than about 2 grams per square meter of film. Also disclosed is an adhesively bonded, solvent resistant protective laminate produced by the process. The film component of the laminate may be composed of a thermoset polymer or a thermoplastic polymer. The film may also be microporous or microapertured.

  • Patent number: 5820761
    Abstract: Organic pollutants in wastewaters are wet-oxidized by addition of pure oxygen or an oxygen-containing gas at temperatures of 80.degree. to 330.degree. C., under pressures of 1 bar to 200 bar and at a pH value below 7. For the wet oxidation process, iron ions and digested sludge or surplus sludge from a biological sewage treatment plant are added to the wastewater.

  • Patent number: 5720578
    Abstract: In the process for treating contaminated mud or suspended earth, the mud or the suspended earth in concentrations of 3% to 25% dry matter is wet-oxidized by addition of pure oxygen or an oxygen-containing gas at a temperature of 120.degree. C. to 220.degree. C., under a pressure of 3 bar to 50 bar and at pH values <7. To accelerate the oxidation reaction, iron ions alone or in combination with quinones or quinone-forming substances are added to the mud or to the suspended earth.

  • Patent number: 5173466
    Abstract: A carbon- and nitrogen-based catalyst consisting essentially of active carbon or active coke and comprising at least 90% by weight of graphite structures containing at least 10% of pores larger than 100 nm in diameter and having incorporated therein an isocyanate which forms C-N-ring structures, the percentage graphite content being at least 90% by weight. The catalayst is especially effective in the low temperature reduction of nitrogen oxides in waste gases.

  • Patent number: 4910005
    Abstract: A process for the reduction of nitrogen oxides contained in exhaust gases comprising reacting the gases with a reducing agent in the presence of a catalyst, the catalyst being based on carbon and having a carbon content greater than 65% by weight and containing 0.1 to 10% by weight of a sparingly soluble oxide of one or more metal selected from the group consisting of Co, Fe, Ni, Cr, V, Mo, W, Cu, Mn and Ti and having a nitrogen content of from 0.5 to 5% by weight, wherein the molar ratio of the reducing agent to the nitrogen oxide is 0.3 to 0.7.
