| 20090084225 | METHODS OF RECOVERING AND PURIFYING SECONDARY ALUMINUM - The invention provides efficient and effective processes for recovering metals such as aluminum, magnesium and lithium from mixed waste sources such as auto shredder residue, aluminum cans, waste particles of aluminum alloy and municipal waste. The metal-waste source is dissolved in a more noble metal solvent at a temperature at which contaminants do not dissolve. The purified metal is then recovered from the solvent, preferably by electrorefining. | 04-02-2009 |
| 20100276298 | CONVERSION OF CARBON TO HYDROCARBONS - The invention provides methods of forming lower alkyls and alcohols from carbon sources thermally and/or electrolytically. | 11-04-2010 |

| 20100219163 | HIGH-VOLTAGE CIRCUIT BREAKER HAVING A SWITCH FOR CONNECTION OF A CLOSING RESISTOR - A high-voltage circuit breaker has an interrupter unit, a closing resistor and a switch which is connected in series with the closing resistor. The interrupter unit has a driven first interrupter contact which can move along an axis and interacts with a second interrupter contact, which is arranged on the axis in order to open and close the high-voltage circuit breaker. The switch has a switching contact which can rotate about a rotation shaft (D) and whose rotary movement is coupled by of a link control to the movement along the axis (A | 09-02-2010 |

| 20090067108 | CLOSING RESISTOR FOR HIGH-VOLTAGE CIRCUIT BREAKERS - A closing resistor arrangement for a high-voltage circuit breaker has a large number of resistor elements and a large number of cooling elements, the cooling elements being arranged in series with one another and being connected electrically in series with one another. The resistor elements, which electrically connect the electrical cooling elements to one another, are arranged between in each case two cooling elements which are arranged in series. | 03-12-2009 |
