20110298183 | SEALING ARRANGEMENT FOR SEALING A PISTON ROD OF A RECIPROCATING COMPRESSOR - Due to increasingly strict requirements and regulations, it is becoming more and more important for piston compressors to reduce the amount of leakage of operating medium through the seal of the piston rod. Conventional seals comprising packing rings and/or packing ring combinations always have a certain amount of leakage, both during operation and when at standstill, which is why they are not usable for certain applications, or the complexity involved in such a seal increases considerably. A further problem involving the seals of piston rods relates to transverse movements by piston rods during which the sealing action of the seal must be maintained. Proposed is, therefore, a sealing arrangement according to the principle of a sealing medium barrier providing that the sealing elements | 12-08-2011 |

20080319701 | METHOD FOR DETERMINING A TIRE POSITION IN A TIRE PRESSURE MEASUREMENT SYSTEM - In a method for transmitting data, the step of transmitting the data representing a measured pressure or pressure variation is repeated with a first repetition rate if no pressure variation has been detected or repeated with a second repetition rate if a specific pressure variation has been detected. The second repetition rate is higher than the first repetition rate. The different repetition frequencies can be used in a method for determining a tire position in a tire pressure measurement system to switch between a first mode of operation and a second mode of operation. The method for determining a tire position evaluates the repetition rate between the received data packets of transmitted data and extracts a pressure variation out of the received data packets. | 12-25-2008 |
