| 20080281141 | Method For Confining a Substance by Vitrification - The present invention relates to a process for the manufacture of a glass frit for the containment by vitrification of a material comprising at least one oxidizable or reducible chemical species, and also to a process for the containment of said material by vitrification. The process for the manufacture of the glass frit comprises a step of incorporating into a raw glass frit at least one redox couple, the nature and the amount of which make it possible to maintain said at least one chemical species in its oxidized or reduced state. The containment process comprises mixing and hot melting the resulting glass frit and the material to be contained. The present invention makes it possible to optimize the containment of pollutants such as radionucleides, metals and metalloids. The material may be nuclear waste or a material derived from the incineration of household refuse. | 11-13-2008 |
| 20090326312 | METHOD FOR VITRIFICATION OF FISSION PRODUCTS - The mass to be vitrified undergoes a reduction operation in order to have the ruthenium pass from an oxidized state to a metal state in order to reduce the viscosity, the electric conductivity and to obtain good chemical kinetics. | 12-31-2009 |

| 20100050670 | WEB COATING APPLICATOR WITH COOLING AND MATERIAL RECOVERY - Apparatus and method for applying a water-based emulsion of silicone fluid to a printed web required to be cooled, such that evaporative cooling of the web is promoted in addition to coating of said web with a silicone material. Water evaporated following the application of the silicone fluid to the web is recovered by condensation on the applicator(s) and reapplied to the web, thus economizing the amount of silicone fluid mixture necessary to provide both cooling and enhanced slip characteristics necessary for further handling and processing of the web. The condensation step is effected by containing the evaporated water from the web within a compact enclosure enveloping both the applicator(s) and the web, and optionally chilling said applicator(s) with a cooling medium, preferably water, by means of said cooling medium flowing through at least one of the applicators. In certain embodiments, in addition to condensing the evaporated water, the airborne silicone mist created in the coating step is captured and is returned to the fluid applicator. | 03-04-2010 |

| 20090092481 | ACTUATING ROD END CONNECTOR - An improved actuating rod end connector is connected with an actuating rod that extends from a turbocharger assembly actuator mechanism. The rod end connector has a body with an opening at one longitudinal end, and the actuator rod is disposed through the opening. An adjustment member is rotatably disposed within the body and has a threaded inside cavity in communication with the opening. The inside cavity is threadably engaged with a threaded outside surface of the actuator rod. The body includes an actuator rod opening disposed therethrough adjacent the adjustment member to receive a section of the actuator rod therein to facilitate contacting the actuator rod disposed within the body from outside of the rod end connector. An attachment opening is disposed through the body to facilitate attachment of the rod end connector with a linkage member, e.g., a linkage member connected with a movable member of the turbocharger. | 04-09-2009 |
