| 05-06-2010 |
| 20110190500 | PROCESS FOR PREPARING CATIONIC RHODIUM COMPLEXES - A process is described for the synthesis of a cationic [rhodium diolefin phosphorus ligand] complex comprising the steps of: (a) reacting a rhodium-diolefin-1,3-diketonate and an acid in a ketone solvent, (b) adding a stabilising olefin to form a stabilised cationic rhodium compound, and (c) mixing a phosphorus ligand with the solution of the stabilised cationic rhodium compound to form a solution of the cationic [rhodium diolefin phosphorus ligand] complex. The solution may be used directly or the complex recovered. In one embodiment, the solution may be combined with a co-solvent and the ketone removed to give a new catalyst solution, from which the complex may be recovered. | 08-04-2011 |
| 20110295008 | PROCESS FOR PREPARING CATIONIC RUTHENIUM COMPLEXES - A process is described for the preparation of a solid cationic [ruthenium (arene) (phosphorus ligand) (halogen)] complex comprising the step of treating the complex with at least one alkane. Further described is a process for preparing a cationic [ruthenium (arene) {4,4′-bis(disubstituted-phosphino)-3,3′-bipyridine} (halogen)] complex comprising the step of reacting [ruthenium (arene) (halogen) 2]2 and a 4,4′-bis(disubstituted-phosphino)-3,3′-bipyridine ligand in a solvent consisting of at least one alcohol. | 12-01-2011 |
| 20120123142 | PROCESS FOR HYDROGENATING KETONES IN THE PRESENCE OF RU(II) CATALYSTS - The present invention relates to a process for hydrogenating a substrate comprising a carbon-heteroatom double bond, the process comprising the step of reacting the substrate with hydrogen gas in the presence of a hydrogenation catalyst, wherein the hydrogenation catalyst is a complex of formula (I): R | 05-17-2012 |

| 20110253092 | OIL DRAIN SYSTEM BYPASS - A system and method are provided for increasing heating of engine oil during a cold start. In one example, engine oil is returned directly to the oil pump inlet, thus bypassing the sump. In this way, a smaller volume of oil receives more heat and is used for lubricating engine components during a cold start, thus providing reduced friction earlier than otherwise possible. | 10-20-2011 |
| 20120006286 | COOLING ARRANGEMENT FOR INTERNAL COMBUSTION ENGINES - A cooling arrangement for an internal combustion engine is described, with a coolant balancing tank which is capable of being filled with coolant and the inlet side of which is connected via a first venting line to an internal combustion engine and/or via a second venting line to a cooler for cooling the coolant, and the outlet side of which is connected via a coolant return line to the inlet side of a pumping device for pumping the coolant through the internal combustion engine. The cooling arrangement has, furthermore, a flow control unit for variably limiting the coolant volume flow in the venting line. | 01-12-2012 |
| 20120036848 | HIGH-PRESSURE EXHAUST-GAS RECIRCULATION SYSTEM WITH HEAT RECOVERY - A method for operation of a high pressure exhaust-gas recirculation (EGR) system is provided. The method includes transferring heat from an exhaust flow through an EGR cooler to an engine coolant, the EGR cooler coupled to an EGR line fluidly coupled in parallel with a turbine and directing a controlled portion of the exhaust flow from the EGR cooler to an engine intake. The method further includes directing another controlled portion of the exhaust flow from the EGR cooler to the surrounding atmosphere. | 02-16-2012 |
| 20120103283 | COOLING SYSTEM - A cooling system for an engine is provided. In one embodiment, an internal combustion engine comprises a cabin heat exchanger circuit including a connecting line opening on an inlet side into a cylinder block coolant jacket, a main coolant pump arranged in the cabin heat exchanger circuit, an auxiliary coolant pump arranged in the connecting line, and a check valve. In this way, additional cooling and/or heating may be provided to the engine and associated components by the auxiliary coolant pump. | 05-03-2012 |
