摘要： The invention relates to a compressor blade of a compressor which, along a main axis, comprises a blade base, a platform area and an adjacent blade profile having a profile tip. The blade profile is configured by a convex wall at the suction end and a concave wall at the pressure end opposite the wall at the suction end. These surfaces extend, with respect to a flow medium, from a leading edge to a trailing edge, a profile center line extending in the center between the two. A front face is arranged on the profile tip at an angle to the main axis, a sealing lip at least partially extending from the leading edge to the trailing edge and the blade profile including the sealing lip having a blade profile height extending in the direction of the main axis. In order to allow for an inexpensive compressor blade having improved aerodynamic properties and a modified sealing lip while having the same sealing properties, the height of the sealing lip is less than 2 percent of the height of the blade profile.

摘要： Silicon-containing residues, as they accumulate especially during the synthesis of organosilanes out of metallic silicon, and especially methyl chloride, are processed according to the invention to briquettes, being additives for the quality adjustment of cast iron being produced in a cupola furnace in order to avoid either costly regeneration for the recovering of the valuable components or the total dumping of said silicon-containing residues. Besides the silicon-containing residue the briquettes contain 1-10 percent by weight of cardboard fiber, 5-40 percent by weight of hydraulic cement and 0-20 percent by weight of additional additives having influence on the quality of the cast iron. The cement- and cardboard fiber-containing briquettes are mechanically and thermally sufficiently stable with respect to the operation of the melting furnace. The yielding rate of the inserted small-sized silicon in the cast iron is about 85% and reaches thereby the same range of lumpy ferrosilicon.
