A turbine blade including an airfoil having a pressure sidewall and a suction sidewall joined together along an upstream leading edge and a downstream trailing edge. The leading edge and trailing edge are formed as substantially straight edges, and portions of the pressure sidewall and suction sidewall adjacent the trailing edge form substantially planar surfaces. The airfoil has an uncoated nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table 1 wherein Z represents a perpendicular distance from a plane normal to a radius of a turbine centerline and containing the X and Y values with the Z value commencing at zero in the X, Y plane at a radially innermost aerodynamic section of the airfoil, and X and Y represent coordinate values defining the airfoil profile at each distance Z which, when connected by smooth continuing arcs, define profile sections at each distance Z.

A wideband antenna includes a grounding unit electrically connected to a ground, a feed-in source for transmitting and receiving radio frequency signals, a first radiating body including a first radiating unit extending along a first direction, a second radiating unit extending along a second direction opposite to the first direction, and a conducting unit extending along a third direction, and a second radiating body including a short-circuit unit electrically connected to the grounding unit, a third radiating unit including a branch to generate a coupling connection effect with the conducting unit via a first distance, wherein an average perpendicular distance between the second radiating body and the grounding unit is smaller than an average perpendicular distance between the first radiating body and the grounding unit.

The invention relates to a valve, in particular a pendulum or slide gate valve, for essentially gastight closing of a flow path (F). The valve includes a valve housing (1) having a first wall (2) which has a first opening (3) and a first valve seat (4), a valve plate (5) having a closing side (6) with a first sealing ring (7) and at least one drive (8). By action of the drive (8), the valve plate (5) is pivotable or displaceable from an opened position (A) essentially parallel to the first valve seat (4), and the perpendicular distance between the valve plate (5), and the first valve seat (4) can be reduced so that, in the closed position (C), the flow path (F) is closed essentially gastight by an axially sealing contact between the first sealing ring (7) and the first valve seat (4). The valve plate (5) includes support part (9), which is connected to the drive (8) and fixes the first sealing ring (7) in the perpendicular direction to the first valve seat (4), and a sealing part (10) which has an inner circumferential area (11) and which is mounted so as to be movable relative to the support part (9) in a direction (Z) essentially perpendicular to the first valve seat (4). The inner circumferential area (11) encloses the first sealing ring (7) in an essentially gastight way with an inner seal. Thus, in the closed position (C), a pressure difference at the valve plate (5) acts essentially on the sealing part (10) so that sealing part (10), decoupled from the support part (9), is supported perpendicularly on a section of the valve housing (1), in particular the first valve seat (4) or a lateral groove (27).
