  • Atmospheric Pressure Plasma Treatment of Gaseous Effluents
    Publication number: 20080234530
    Abstract: The invention relates to a method for the conversion of a gas or gas mixture and, in particular, a fluorinated gaseous effluent. According to the invention, at least one bond between two atoms of at least one molecule of the gas or gas mixture is broken under the influence of an electric and/or magnetic field to which the gas or gas mixture is subjected. The gas or gas mixture stream is injected through the electric and/or magnetic field in a non-rectilinear manner in order to increase the distance travelled by the gas molecules through the field and, in this way, increase the effectiveness of the conversion of the gas or gas mixture molecules.

  • Apparatus and process for delivering an abrasive suspension for the mechanical polishing of a substrate
    Patent number: 6125876
    Abstract: An apparatus for delivering abrasive suspensions includes a reservoir containing an abrasive suspension, a loop for delivering the abrasive suspension to a point of use, the loop being connected to the reservoir, a pumping arrangement for circulating the abrasive suspension in the loop and for ensuring its return into the reservoir, the loop and the reservoir being arranged for recovering the abrasive suspension after circulation in the loop at a recovery point of the reservoir, and a control system for controlling the pumping arrangement so as to maintain a continuous circulation of the suspension.
