| 20080257321 | Valve and Cylinder Head Cover for Crankcase Ventilation of an Internal Combustion Engine - A valve for crankcase ventilation of an internal combustion engine comprises a fresh-air side for connection with an intake section of the internal combustion engine, an engine side for connection with the crankcase and a valve insert movable as a whole for changing the flow resistance through the valve. Said valve inset is held inside said valve without pre-load. Said valve insert is designed to be freely displaced to a deventilation limit-stop position under negative pressure on the fresh-air side relative to the engine side, and to be freely displaced to a ventilation limit-stop position under excess pressure on the fresh-air side relative to the engine side. The valve insert id designed to open a deventilation cross-section in the deventilation limit-stop position and to open a deventilation cross-section that is different from the ventilation cross-section in the ventilation limit-stop position. | 10-23-2008 |
| 20090263261 | DEVICE FOR RETURNING OIL SEPARATED FROM BLOW-BY GASES AND ACCUMULATED IN AN ACCUMULATION CHAMBER - The invention relates to a device for returning oil separated from blow-by gases and accumulated in an accumulation chamber ( | 10-22-2009 |
| 20100050962 | Flexible tongue valve for an oil separation device in the crankcase ventilation of a motor vehicle - A flexible tongue valve for an oil separation device in the crankcase ventilation of a motor vehicle includes a flexible tongue which on one end is suspended in a cantilevered manner and on the opposite end interacts with a valve seat. The flexible tongue comprises a bistable portion with a first stable position and a second stable position, wherein the bistable portion consists of a bimetal and is adapted to automatically abruptly switch between the first stable position and the second stable position depending on temperature. | 03-04-2010 |

| 20090026181 | RADIO FREQUENCY POWER SUPPLY - A plasma supply device includes a full bridge circuit that is connected to a DC power supply and that has two half bridges each with two series connected switching elements. The plasma supply device further includes a primary winding of a power transformer connected to centers of the half bridges between the switching elements. The primary winding includes a tapping connectable to an alternating current center between the potentials of the DC power supply. | 01-29-2009 |
| 20090026964 | High Frequency Power Supply - For determining a wave running time between a RF source in a plasma power supply device and a load connected to the plasma power supply device, an RF pulse is transmitted forwards from the RF source to the load. The pulses are reflected by the load and transmitted backwards to the power source. A return time measured on arrival of the pulse(s) at the inverter is used to determine a wave running time. | 01-29-2009 |
| 20090026968 | PLASMA SUPPLY DEVICE - A plasma supply device generates an output power greater than 500 W at an essentially constant basic frequency greater than 3 MHz and powers a plasma process to which is supplied the generated output power, and from which reflected power is returned to the plasma supply device. The plasma supply device includes at least one inverter connected to a DC power supply, which inverter has at least one switching element, and an output network. The output network is arranged on a printed circuit board. The output network can therefore be designed low priced and accurately. | 01-29-2009 |
| 20100171428 | DRIVING SWITCHES OF A PLASMA LOAD POWER SUUPLY - Operation of a plasma supply device having at least one switching bridge with at least two switching elements, and configured to deliver a high frequency output signal having a power of >500 W and a substantially constant fundamental frequency>3 MHz to a plasma load is accomplished by determining at least one operating parameter, at least one environmental parameter of at least one switching element and/or a switching bridge parameter, determining individual drive signals for the switching elements taking into account the at least one operating parameter, the at least one environmental parameter and/or the switching bridge parameter, and individually driving the switching elements with a respective drive signal. | 07-08-2010 |
