A turbine blade is provided, comprising a stator-side end located toward a stationary stator cylinder of the turbine, a rotor-side end located toward an axial rotor of the turbine, a leading edge located between the stator-side end and the rotor-side end, a trailing edge located between the stator-side end and the rotor-side end and located down-stream of the leading edge with respect to a fluid flow direction, wherein the rotor-side and stator-side ends have a negative sweep angle as measured between the instantaneous tangent of the blade surface and the fluid flow direction. Also, a turbine blade is provided, comprising a stator-side end located toward a stationary stator cylinder of the turbine, a rotor-side end located toward an axial rotor of the turbine, a delivery side located between the stator-side end and the rotor-side end, a suction side located between the stator-side end and the rotor-side end and located down-stream of the leading edge with respect to a fluid flow direction, wherein the rotor-side end is inclined toward the delivery side and the stator-side end is inclined with respect to a fluid flow direction.

An integrally bladed rotor disk (20) for a turbine, including rotor blades (40), which are joined in a substance-to-substance bond to a disk element (30), and a sealing device (60) for preventing or reducing the extent to which cooling air is able to flow from a high-pressure side (12) of the rotor disk (20) through openings (24) on the rotor disk (20) to a low-pressure side (14) of the rotor disk (20).

Wing-propulsion unit combination comprising a wing (W) with a main wing (W1) and a propulsion unit (E) with a pre-mix chamber (E1), a combustion chamber and a hot air chamber (E2), further comprising: a) a propulsion unit tap air channel (2) running along the span direction (SW) and along the front edge of the main wing, said tap air channel comprising a propulsion unit tap air inlet apparatus (2-1) that is coupled to a propulsion unit hot air chamber (E2), and comprising a propulsion unit tap air outlet apparatus (2-2) that is made up of a mouth at the main wing (W1) or a connecting part for coupling the propulsion unit tap air channel to a user of the propulsion unit tap air, b) a surrounding air channel (10) running along the propulsion unit tap air channel (2) comprising a surrounding air inlet apparatus (10-1) that is located at a component of the airplane (AC) facing the proper flow direction (S) of the airplane (AC) and that comprises an opening (10-3) for letting in surrounding air into the surrounding air channel (10), and comprising a surrounding air outlet apparatus (10-2) with a passage between the surrounding air channel (10) and a pre-mix chamber (E1) of the propulsion unit (E), so that the arrangement (1) of propulsion unit tap air channel (2) and surrounding air channel (10) forms a heat exchange apparatus for cooling of the air flowing in the propulsion unit tap air channel (2) and so that the surrounding air passing through the surrounding air channel (10) is fed to the combustion chamber in the propulsion unit.

The purpose of the present invention is to carry out press working by a free bending method on a blank comprising an ultra high-strength steel plate and manufacture a press component without cracks ina flange on the inside peripheral side of a curved part. A press component 11 having a hat shaped cross-sectional shape and a curved part 13 is manufactured by carrying out cold press working on a blank 24 comprising an ultra high-strength steel plate with a tensile strength of 1080 MPa or higher by the free bending method disclosed in the pamphlet for International Publication No. 2011 / 145679. By means of press working, a material flow facilitating part 19 is disposed in the vicinity of the portion of the blank 24 to be formed into a flange 11e that is on the inside peripheral side of the curved part 13 of the press component 11, and the material flow facilitating part 19 increases the flow amount by which the portion of the blank 24 to be formed into an end part 11f of the press component 11 flows into the portion of the blank 24 to be formed into the flange 11e on the inside peripheral side of the curved part 13 of the press component 11.

The present invention pertains to antimicrobial compositions comprising inter alia at least one alkenyl- and / or alkynyl-substituted polysiloxane, at least one polysiloxane comprising silicon-bonded hydrogen atoms, and at least one hydrosilylation catalyst, as well as antimicrobial silicone gels, wound dressings, and methods of preparing the above.

An agitating ball mill includes a comminution vessel surrounding an agitating shaft which is provided with a product inlet and a product outlet, wherein the comminution media located within the comminution vessel is activated through the rotation of the agitating shaft and held back in the comminution chamber by a separating and / or pre-classifying device. For optimum energy and space utilization a pre-crushing device is arranged upstream of the comminution chamber. The pre-crushing device includes either a static or dynamic gap guard.

When a louver member able to diffuse exhaust gas over the entire area of a catalytic converter is incorporated in the exhaust passage, passage resistance of the exhaust gas increases and, in addition, the time to complete a warm-up of the internal combustion engine is extended, and this leads to deterioration of fuel economy. An exhaust gas treatment apparatus for an internal combustion engine includes an exhaust gas treatment unit (21, 22) arranged in an exhaust passage (18a) of the engine (10), an exhaust gas burble zone (Z1, Z2) in which an exhaust gas flowing along a part of a wall face (18e), which defines the exhaust passage, burbles away from the part of the wall face, and a plasma actuator (23, 31) arranged at the part of the wall face of the exhaust passage in the exhaust gas burble zone and configured to generate air current toward the exhaust gas treatment unit along the part of the wall face.
