  • Patent number: 6792189
    Abstract: An optical waveguide capable of having various characteristics and a method of manufacture thereof as well as a method of manufacturing a crystal film are provided. An optical functional material KTaxNb1-xO3 is used as an optical waveguide. The input optical signal is transmitted to the KTaxNb1-xO3 film. The KTaxNb1-xO3 film undergoes changes in optical property when an external voltage signal is applied to the electrode. Therefore, as it passes through the KTaxNb1-xO3 film, the input optical signal is modulated by the characteristic change. The modulated optical signal is taken out as an output optical signal.

  • Patent number: 6743371
    Abstract: The present invention relates to a magneto sensitive fluid composition and a process of its preparation. The electrical conductivity of the composition varies reversibly in the presence of an external magnetic field. The composition, which is practically an insulator, starts behaving as a conductor in the presence of a magnetic field. The fluid is basically a magnetrheological composition in which the magnetic sensitive particles are admixed with conductive additives in the form of conductive metallic or non-metallic powder. The change in electrical conductivity of the composition is in addition to the change in rheological characteristics of the composition in the presence of an external magnetic field.

  • Patent number: 6656344
    Abstract: A sequential processing for heavy petroleum residues is disclosed which uses a separate mixture of catalyst and adsorbent. The solid adsorbent and FCC (fluids catalytic cracking) catalyst particles differ significant at least on particle size or density or both. The adsorbent preferably consist of calcined coke or metal oxides of Al, Si, or Mg having enhanced ability of selectively capture different impurities of the residual oil. The adsorbent particles first treat the residual hydrocarbons in the riser bottom end subsequently the actual catalyst tales care of catalytic cracking in the upper section of the riser. The spent solid mixture is fed to the catalyst separator which uses steam at sufficiently high velocity but at lower temperature to lift the catalyst particles out of the separator. Such a novel low temperature faster separation minimizes Vanadium mobility and deactivation of the catalyst. A net coke stream is withdrawn from the separator/burner especially while processing residues above 5 wt % CCR.
