  • Positioning apparatus
    Patent number: 8973910
    Abstract: A positioning apparatus includes a base plate and a deflection mechanism mounted upon the base plate. The deflection mechanism includes a stationary platform, a rocker assembly and a deflection platform. The stationary platform is mounted over the base plate for placing and positioning a workpiece. The deflection platform is tiltably mounted over the stationary platform via the rocker assembly and the height of the stationary platform itself is adjustable. The rocker assembly comprises a first rocker and a second rocker of different lengths.
    Type: Grant

  • Catalytic removal of sulfur dioxide from flue gas
    Patent number: 5853684
    Abstract: The present invention provides novel catalysts for the simultaneous removal of SO.sub.2 and NO.sub.x from flue gases. The catalysts may be supported or unsupported, pretreated or untreated, but allow the simultaneous reduction of SO.sub.2 to S and NO.sub.x to N.sub.2. Elemental sulfur is a useful byproduct of the process.

  • Catalytic removal of sulfur dioxide form flue gas
    Patent number: 5804153
    Abstract: The present invention discloses a method for the catalytic reduction of sulfur dioxide, for example in flue gas, by carbon monoxide using lanthanum oxysulfide as the active catalyst. The catalyst is prepared from lanthanum oxide by hydration and sulfidization, the latter step being carried out in the gas stream itself. This method of preparation has more general applicability and can also be used as a method for the preparation of lanthanum, yttrium, gadolinium and lutetium oxysulfides generally.
