20080289900 | Noise Damper for a Compressed Air Device - A noise damper for a compressed air device includes a tubular housing part provided with an air inlet and an inserted insulating material, in particular, an inserted knitted fabric roll. The air inlet is embodied in the envelope of the tubular housing part such that the supplied air tangentially flows through the insulating material or the knitted fabric roll, is radially deviated inside the tubular housing part, and axially flows out from at least one end of the tubular housing part. | 11-27-2008 |

20080231371 | Amplifier Circuit With Adjustable Amplification - An amplifier circuit has an amplifier element having an amplifier element input and an amplifier element input impedance, an amplification adjuster adapted to adjust an amplification of the amplifier element, an amplifier circuit input coupled to the amplifier element input, an impedance element having a alterable impedance value and being coupled to the amplifier circuit input, and an impedance adjuster adapted to adjust the impedance value of the impedance element as a function of the amplification of the amplifier element. | 09-25-2008 |
20080282808 | Measuring Means for Measuring a Flow Rate of a Medium Independently of the Medium - A measurer for measuring a flow rate of a medium which may be multi-component or heterogeneous, independently of the medium, a signal-generating unit generating a transmit signal on the basis of a reference signal of a signal generator and transmitting same by means of a stimulator via the flowing medium. This signal is received by a sensor and passed on to an evaluating unit which is implemented to determine a signal transfer time based on a plurality of mutually corresponding locations of a waveform of the receive signal and the waveform corresponding to the reference signal and the flow rate of the medium based on the signal transfer time and the certain distance between the stimulator and the sensor. | 11-20-2008 |
