Abstract: An apparatus for purifying a process gas containing at least one pollutant gas, having a reactor vessel, has a cylindrical region and a tapering region, and into which oxygen or an oxygen-containing gas can be introduced as a reaction gas into at least one gas inlet and can be discharged through at least one gas outlet. The at least one gas inlet introduces a defined volumetric flow of the reaction gas into the reactor vessel tangentially to a circumferential surface of the cylindrical region. The apparatus may have a pollutant gas inlet, which introduces a defined volumetric flow of the process gas containing at least one pollutant gas into the reactor vessel, so that the at least one pollutant gas and the reaction gas are mixed with each other in the direction of the gas outlet and chemically react with each other on their way through the reactor vessel.

Abstract: A fiber tape for producing fiber reinforced parts is provided. The fiber tape includes a fiber layer and a binder material securing the fibers of the fiber layer to each other. The binder material is provided as a binder mesh covering at least an upper surface and/or a lower surface of the fiber layer.

Abstract: A high-strength steel sheet comprises, by weight, not less than 0.25% and not more than 0.5% of C, not less than 4% and not more than 14% of Mn, not less than 6.5% and not more than 9.5% of Cr, and not less than 0.3% and not more than 3% of Si. The high-strength steel sheet satisfies formulas 1 and 2, formula (1) being 12?2.0Si+5.5Al+Cr+1.5Mo?25 and formula (2) being 13?30C+0.5Mn+0.3Cu+Ni+25N?17, and mainly consists of austenite, and the high-strength steel sheet has yield strength of not less than 1000 MPa and total elongation of not less than 20%. In formulas 1 and 2, each element in the above formulas indicates the content, in weight %, of the element.
