| 20110257435 | FUNCTIONALIZED CATIONIC POLYAMINES AND THEIR USE TO REDUCE THE NDMA FORMATION DURING THE TREATMENT OF AQUEOUS SYSTEMS, AND APPLICATIONS IN THE WATER TREATMENT INDUSTRY, INCLUDING WASTEWATER AND DRINKING WATER TREATMENT PROCESSES - New water treatment chemicals and corresponding water treatment or more generally aqueous systems treatment processes are provided, which greatly attenuate the NDMA problem, that is, decrease the formation of NDMA during the water or aqueous system treatment namely in the presence of a disinfectant, and decrease too the level of NDMA in the so treated water of the aqueous system, and in the end products such as drinking water. | 10-20-2011 |

| 20120058922 | NOVEL FORMULATIONS OF WATER-SOLUBLE POLYMERS AND STABILIZING ADDITIVES FOR INJECTING A SINGLE COMPOUND USEABLE IN INJECTION FLUIDS FOR CHEMICAL ENHANCED OIL RECOVERY - Composition based on anionic polymers or water-soluble amphoteric (co)polymers suitable for viscosifying the injection fluids for oil recovery, characterized in that, before dilution with the injection fluid, it further contains at least 3 stabilizing agents selected from the group comprising oxygen reducing agents, precipitating agents, free radical scavengers, complexing agents and sacrificial agents, the said stabilizing agent being suitable for preventing the chemical degradation of the polymer once the polymer is introduced into the injection fluid. | 03-08-2012 |

| 20090123307 | ELECTRICAL DEVICE AND PLUG FOR AN ELECTRICAL DEVICE - Known pumping devices have a connection lid, a connection cap slipped over the connection lid, a hollow chamber formed between the connection lid and the connection cap, and electrical connections that extend through the connection cap into the hollow chamber. It is disadvantageous that when fuels containing water are being pumped, such as ethanol, corrosion can occur at the electrical connections and at the uninsulated cable segments that are exposed to fuel near the electrical connections, for instance at the electrical coils or flexible cables of the carbon brushes, and in the final analysis this leads to an interruption in the electrical contact and thus to failure of the pumping device. In the electrical device of the invention, corrosion of the electrical connections and of the electrical components adjoining them upstream and downstream is avoided entirely or at least greatly diminished. According to the invention, the electrical connections are each provided in separate chambers of the hollow chamber. | 05-14-2009 |
