摘要： A blade of a turbomachine or a flying machine includes a blade airfoil extending in a radial direction from a blade root to a blade tip. The blade airfoil has an inflow-side leading edge, an outflow-side trailing edge, a pressure side and a suction side. A surface of each of the pressure side and the suction side extends between the inflow-side leading edge and the outflow-side trailing edge. The blade tip has an end face with a camber line that extends from the inflow-side leading edge to the outflow-side trailing edge. At least one tip-side recess forms a depression from the end face into the blade airfoil, the depression extending continuously from the pressure side to the suction side and having a partial length of the camber line.

摘要： A gas turbine is disclosed which includes an annular combustion chamber defined by an inner wall and an outer wall. A stator airfoil row can be defined by an annular inner stator wall and an annular outer stator wall housing a plurality of stator airfoils, and at least a rotor airfoil row defined by an annular inner rotor wall and an annular outer rotor wall housing a plurality of rotor airfoils. A gap is arranged, for example, between at least one of the inner stator wall and the inner combustion chamber wall, and the outer stator wall and the outer combustion chamber wall, upstream of said stator airfoil row. A border of at least one of the inner and outer stator wall facing the gap can be axisymmetric. A zone of at least one of the inner and outer stator wall downstream of the gap and upstream of the stator airfoils can be non-axisymmetric and defines bumps arranged to locally increase the static pressure of a fluid flow passing through said stator airfoil row to increase the uniformity of the static pressure.

摘要： The invention relates to a material for the formation of connections between two objects, for example between a roofing tile and a ridge tile. This material is a deformable filter foam, which is impregnated with a substance which is cured when exposed to air. Before the connection is formed, the filter foam with the substance impregnating it, is sealed airtight. When the connection is to be formed, the airtight seal is removed and the substance introduced between the objects to be connected. Due to the exposure to air, which is now possible, the substance becomes cured. This lends the previously soft filter foam a solid structure.

摘要： Process and arrangement for producing tetrahydrofuran from a hydrous butane diol solution contaminated by light volatile, organic compounds, comprising the following process stages: a) Distillative removal (K1) of the light volatile, organic compounds contained in the hydrous butane diol solution 1. b) Dehydrating (R) of the thus prepurified hydrous butane diol solution 3 over an acidic aluminum oxide catalyst. c) One-step or multi-step distillation (K2) of the thus obtained high-tetrahydrofuran fraction 8 for obtaining a pure tetrahydrofuran. In addition, a separation of the water from the hydrous butane diol solution to water contents of from 2 to 70% by weight, particularly 2 to 10% by weight, can take place before the dehydrating of the butane diol.
