A turbo-machine includes at least two rotors which are mounted so as to be rotatable in opposite directions relative to one another about a rotational axis and on which are arranged blades or vanes, having a rotatably mounted machine shaft and having a drive mechanism which connects the machine shaft to the at least two rotors and which converts a rotational movement of the machine shaft into rotational movements of the rotors in opposite directions relative to one another or vice versa. In at least one embodiment, the turbo-machine is designed to utilize the hydrodynamic advantages of counter-rotating rotors yet at the same time have comparatively low mechanical complexity and component density and therefore increased reliability. This is possible according to at least one embodiment of the invention in that the turbo-machine has a housing which forms a duct for a flow of a fluid, wherein the rotors are arranged in series in the duct in the flow direction of the fluid, the machine shaft and the rotors are of annular design and are rotatably mounted in the housing, and wherein the annular rotors have in each case a ring inner side and a ring outer side, wherein the blades or vanes are arranged on the ring inner side.

Device and method for processing and measuring properties of a moving rod of tobacco processing industry. Device includes a microwave measurement device in which endless rod is conveyable through microwave resonator from input side to output side. Microwave generator is included to generate a measurement signal having output frequency f0 and to supply measurement signal to input side of microwave resonator. At least one analysis arrangement includes a mixer, a low-pass filter, and an analog-to-digital converter in series, and local oscillator to generate a signal with local frequency fLO. Mixer is connected to port of microwave resonator and to output of local oscillator to generate difference signal of frequency fIM, which is less than f0 and corresponds to a difference of frequencies f0 and fLO. Low-pass filter is structured to pass output signal of mixer with intermediate frequency fIM, and filter higher frequency signal portions.

Device for processing and measuring properties of a moving rod of material of the tobacco processing industry includes a microwave resonator structured and arranged so that the rod of material is conveyable through the microwave resonator. Includes microwave generator with output frequency f0, and frequency stabilized oscillator to generate intermediate frequency fIM that is less than f0. Single sideband modulator supplies microwave resonator with a sideband signal having a sideband frequency shifted with respect to output frequency f0 by intermediate frequency fIM, and at least one analysis arrangement includes single sideband demodulator, low-pass filter, and analog to digital converter arranged in series. Single sideband demodulator receives a measurement signal of the sideband frequency transmitted or reflected from the microwave resonator, and receives output frequency f0. Low-pass filter passes an output signal of single sideband demodulator with intermediate frequency fIM, and filters out higher frequency signal portions.
