Abstract: A resonator device for testing a material quantity in the tobacco-processing industry for existence of at least one foreign substance and/or for detecting at least one of weight, density and humidity level of the material includes a resonator housing having a through opening for the material to pass through and a testing region located inside the resonator housing to which the material can be moved at least in part. The device has at least one element that increases energy density of electromagnetic waves for increasing the energy density in at least a portion of the testing region.

Abstract: To integrate audiovisual, encoded information into one predefined, frame-structured transmission standard, individual data streams are multiplexed into one or a plurality of data channels of the frame-structured transmission standard. In addition, the capabilities of the communicating terminals are exchanged.

Abstract: A method of detecting impurities in a mass, such as detecting metallic and/or plastic particles in a stream of tobacco particles or filter material for tobacco smoke, includes the steps of moving the mass relative to a microwave field and/or vice versa, and analyzing the influence of the mass upon the microwave field. The analyzing step involves simultaneously measur- the actual values of a first and a second parameter of the microwave field, ascertaining the presence or absence of those changes of the parameters which are attributable to the presence of impurities in the mass, determining whether or not the changes are within an acceptable range, and generating signals for segregation of impurities-containing portions of the mass from the other portions when the changes are outside of the acceptable range.

Abstract: A computer for data processing and a method for data processing using a computer, each of which is used for reversing, with the aid of a circuit arrangement, the bit sequence of the information, which was coded with a reversible Huffman code, when an error occurs, so that the computer decodes the reversed bit sequences using a suitable code table. In the computer, a data buffer is connected to a register in such a way that the bit sequence is reversed when transferred from the data buffer to the register. The bit sequence is not reversed when it is retransferred from the register into the data buffer. In this way, information which is located after the error does not get lost. Since to reverse the bit sequence, the end of the bit sequence, designated by a synchronization bit sequence, must be found, the synchronization bit sequence is disposed at byte boundaries due to padding bits. In this way, synchronization bit sequences are located only at byte boundaries.

Abstract: At least one characteristic, such as the mass/density and/or moisture content and/or dielectric constant, of a substance (such as the rod-like tobacco filler of a continuously advancing cigarette rod or a continuously advancing rod-like filler of filter material for tobacco smoke) is ascertained by an evaluating circuit receiving high-frequency signals from a resonator arrangement which receives microwave signals at least at two different frequencies from one or more microwave generators. The substance is caused to advance through a dielectric resonator of the resonator arrangement, and the high-frequency signals are influenced by the substance. For example, the circuit can compare first and second curves of high-frequency signals which respectively are and are not influenced by a selected substance; the curves can have sloping flanks and each of the two frequencies can be allocated to a sloping flank of a curve.
