The invention further provides a process for the manufacture of sulphur pellets comprising at least one H2S-suppressant, comprising the steps of: (a) mixing elemental sulphur, one or more H2S-suppressants and optionally a filler in a mixing unit to obtain a mixture; (b) shaping and/or palletizing the mixture obtained in step (a) in a palletizing unit to obtain H2S-suppressant-comprising sulphur pellets. The invention further provides a process for the manufacture of a sulphur-comprising asphalt paving mixture comprising the steps of: (i) preheating bitumen at a temperature of between 140 and 180° C.; (ii) preheating aggregate at a temperature of between 140 and 180° C.Type: GrantFiled: December 8, 2004Date of Patent: September 27, 2011Assignee: Shell Oil CompanyInventor: Imants Deme

Patent number: 8024953Abstract: There is provided a lubricant for hot plastic working, which contains 20 to 40 mass % of iron oxide and 10 to 30 mass % of sodium silicate, wherein impurities are 3 mass % or less, and the lubricant contains 40 to 60 mass % of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.Type: GrantFiled: June 28, 2010Date of Patent: September 27, 2011Assignee: Sumitomo Metal Industries, Ltd.Inventors: Kenichi Saito, Sumio Iida

Publication number: 20110226161Abstract: Multilayer pearlescent pigments with a silver interference color, based on platelet-shaped transparent substrates with an optically active coating, where the optically active coating includes at least a) a high-index layer A having a refractive index n?1.8 b) a low-index layer B having a refractive index n<1.8 c) a high-index layer C having a refractive index n?1.8 and also d) optionally an outer protective layer D. The multilayer pearlescent pigments have the indices D10, D50, D90 from the cumulative frequency distribution of the volume-averaged size distribution function, with a span ?D of 0.7-1.4, the span ?D being calculated in accordance with the formula ?D=(D90?D10)/D50. The invention further relates to a method for producing these multilayer pearlescent pigments, and also to their use.Type: ApplicationFiled: August 9, 2010Publication date: September 22, 2011Inventors: Dirk Schumacher, Michael Grüner, Günter Kaupp

Patent number: 8016935Abstract: An anticorrosion ferrite-based pigment, derived from a hydrometallurgical purification process of EAF dust. EAF dust is generated in an electric arc furnace for carbon steel production by processing scrap metal, direct reduced iron and/or pre-reduced hematite, and using CaO-rich slag; from a condensation reaction of metals vapors of Fe, or Zn and of Mn, Mg, Si and/or Al, and suspended CaO particles and oxygen. The pigment contains a non-toxic amount of lead, and includes condensed metal oxides, comprising ferrites MOFe2?3, M being Zn, Fe, Mn and Mg, and combinations thereof. The condensed oxides have ferrite structures preserved from the EAF dust, and form aggregates thereof. The pigment includes CaO entrapped by the ferrite structures and being partially available to react with humid air and/or water to protect the substrate against corrosion. The pigments are coated or uncoated. They are used for antifouling or paint formulations.Type: GrantFiled: June 19, 2006Date of Patent: September 13, 2011Assignee: Ferrinov Inc.Inventors: Maurice Morency, Guoji Shan, Denise Fontaine
