Abstract: The invention relates to a wind farm having a multiplicity of wind energy installations (11; 12, WEC). The electrical energy produced by the wind energy installations (11, 12, WEC) is transferred to a public electricity grid system (16) at a transfer point (15). The public electricity grid system (16) presets nominal values for the transfer point (15). A measurement sensor (29) measures electrical actual values at the transfer point (15). According to the invention, a master regulator (17, 27) which is associated with an upper control level, and a plurality of submaster regulators (18, 19, 30, 32, 33, 34), which are associated with a lower control level, are provided. The master regulator (17, 27) uses a difference between upper nominal values and upper actual values at the first control level to determine a preset for the second control level. The submaster regulators (18, 19, 30, 32, 33, 34) take the presets as lower nominal values and, on the basis of a difference between the lower nominal value and a lower actual value, make presets for a plurality of wind energy installations (11, 12, WEC). The invention also relates to a method for controlling a wind farm such as this. The invention allows a high level of control accuracy to be achieved even in large wind farms.

Abstract: To assist in minimizing interference, a bandwidth range can have guards on either side to reduce leakage into neighboring bandwidth ranges. However, in relatively low power situations the risk of leakage is reduced. Therefore, the guard bandwidths can be used to open new channels upon which information can be transmitted. Thus, there can be a larger amount of bandwidth used while still retaining protective aspects, such as low interference to neighboring bands. Using the guard bandwidth to transmit new channels facilitates backward compatibility since legacy devices do not commonly monitor the guard bandwidth.  These techniques can also be used at high power base stations by advertising a larger guard than necessary to legacy devices and using the additionally created guard bandwidth to transmit new channels.

Abstract: The invention relates to a hand pliers for assembly purposes, more particularly for the assembly of pipe connections at pipe systems, said pliers comprised of two limbs which are rotatably connected to one another via a first link joint (1) and which by means of this link joint (1) are divided into an assembly limb and a handle limb (2,3), wherein the first handle limb (3) is divided into an off-handle lever (14) and into a handle-near lever (15) and wherein these two levers (14, 15) are rotatably connected to one another by means of a bolt (16) via a second link joint, wherein a tension wheel (17) and a ratchet wheel (18) with external toothing (27) connected torsionally proof to it are pivotably arranged on the bolt side by side (16) in axial direction, and wherein the tension wheel (17) engages into a tension means (20) that connects both handle limbs (2,3) to one another, and wherein a spring-loaded dog ratchet (25) is arranged at the handle-near lever (15), said dog ratchet engaging into the ratchet wheel (18) in such a manner that when the handle-near lever (15) makes a latching movement the ratchet wheel (18) and the tension wheel (17) execute a rotation that causes the closing of the pliers, with a spring-loaded arrest ratchet (30) being provided for which also engages in the ratchet wheel (18) and permits a rotation of the ratchet wheel (18) on closing the pliers, but which prevents its rotation in the opposite direction. It is the object of the present invention to provide a hand pliers whose arrest ratchet can be released even if subjected to great assembly forces. To solve this task the invention proposes a switch (33) by the actuation of which the direction of the spring loading of the arrest ratchet (30) is reversible in such a manner that the actuation of the switch (33) takes the effect that the engagement of the arrest ratchet (30) into the ratchet wheel (18) is abolished.
