Abstract: An exemplary laser microscope can be provided, comprising at least one first laser source which emits at least one (e.g., pulsed) excitation beam, a scanning optical configuration (e.g., configured to scan the excitation beam over the surface of a sample), a focusing optical configuration (e.g., configured to focus the excitation beam onto the sample), and at least one detector configured to detect light emitted by the sample due to an optical effect in response to the excitation beam. A second laser source facilitates a pulsed ablation beam for a local ablation of the material of the sample. The ablation beam can be guided to the sample via the scanning and focusing optical configurations. The first and second laser sources can be fed by a mutual continuous wave pump laser and/or a mutual pulsed pump laser. The first laser source can emit pulses with at least two different wavelengths.

Abstract: A method for operating a redundant ringlike communications network, that communicates bidirectionally, includes communicating at least one primary participant and at least two secondary participants with one another by a data transmission device; communicating the secondary participants with one another directly by the data transmission device, indirectly by the primary participant and the data transmission device, or both; and exchanging by the participant the data to be exchanged between the secondary participants, between its data transmission device connections.

Abstract: The invention relates to a novel covering layer for electrophotographic printing rollers with improved scratch resistance. Said covering layer consists of between 50 and 75 wt. % of cycloaliphatic epoxides, between 20 and 60 wt. % of aminofunctional silica nanoparticles, and between 0 and 2 wt. % of perfluoroalkyltrialkoxysilanes. The aminofunctional nanoparticles are produced from aminoalkyltrialkoxysilanes preferably by means of sol/gel technology.

Abstract: In a method for operating a network having a primary station and at least two secondary stations, the primary station communicates with the secondary stations. The secondary stations communicate with one another via cross communication in the form of telegrams which are generated in the context of communications cycles.

Abstract: For operating a network having a primary station and at least two secondary stations, the primary station communicates with the at least two secondary stations, and the at least two secondary stations communicate with one another to furnish a cross communication, and the cross communication is effected by telegrams which are generated in the context of communications cycles.

Abstract: To prepare an absorption muffler for motor vehicles with a sound-absorbing material arranged in a hollow space of an exhaust muffler body in the form of glass wool (2), which is introduced into the hollow space in the form of an expanded, endless glass fiber roving, it is proposed that the exhaust muffler body (1) be completely prefabricated and assembled before the glass wool (2) is introduced into the prefabricated, assembled exhaust muffler body (1) from the outside.

Abstract: A process is for producing electrophotographically active titanylphthalocyanine. In the process, which has an improved space-time yield, titanylphthalocyanine is dissolved in pentafluoropropionic acid and a solvent of the group comprising halogenated alkanes/aromatic compounds or halogenated alkanes/aromatic compounds and sulphonic acids. The active form is precipitated by precipitation with water in the presence of a further polar organic solvent. A mixture of pentafluoropropionic acid and methylene chloride and a mixture of p-toluene sulphonic acid and methane sulphonic acid are particularly suitable as solvents. The precipitated product processes very good electrophotographic properties.
