Abstract: An estimation unit can estimate, on a real-time basis, a maximum power generation capacity of a single cycle or combined cycle gas turbine power plant. For example, the actual power output and the maximum power generation capacity can be calculated relying on a mathematical process model. Subsequently, the calculated actual power output can be compared with the measured power output yielding a model-estimation error. Based on the model-estimation error, a correction signal can be deduced, to correct the calculated maximum power generation capacity. A controller can maintain a specified power reserve. The controller can use an estimate of the maximum power generation capacity as a reference, subtract a load offset, and apply the resulting signal as upper limit of the load set-point.

Abstract: A tube of a surgical microscope has a base part, intermediate part pivotable about a rotational axis on the base part, and an ocular part pivotable about a rotational axis on the intermediate part. The imaging beam path is guided through the base part, intermediate part and pivotable ocular part. The tube has a tube lens system which transfers a parallel imaging beam path into an intermediate image. The parallel imaging beam path enters via an opening in a connecting piece of the base part. The tube has a first displaceable mirror element movable about the rotational axis on the base part. The tube has a further displaceable mirror element movable on the intermediate part about the rotational axis. The first mirror element directs the imaging beam path to the further mirror element. The first mirror element and further mirror element are mounted in the imaging beam path between a lens unit having positive refractive power and a lens unit having negative refractive power.

Abstract: Screwing tool (1) having a grip (2) and a shank (3), which is received removably in a cavity (4) open toward an end of the grip (2) and which at its free end has an actuating portion (5). The shank (3) is retained in a position of use such that it is fixed in terms of rotation on the grip, to avoid sliding in the axial direction, by a retaining element (14) associated with the grip (2). The retaining element (14) can be displaced into a removal position by displacement of an actuating member (6) in order for the shank to be removed from the grip (2). In a storage position, a large part of the shank (3) is located in the cavity (4), where it is held by a holding element (H). The holding element (H) is releasable, so that part of the shank (3) can be moved out.

Abstract: The casting chamber for a die casting machine includes a casting chamber jacket in which, over its entire length, there is provided an inner jacket defining the sliding surface for the pressure piston. In order for excessive heat in the inner jacket to be uniformly distributed and passed to the casting chamber jacket, copper rings are inserted in the inner jacket (3), the latter being pressed against the casting chamber jacket by means of screws threaded into a conical wedge. In this manner, heat distortion of the casting chamber can, for the first time, be held within limits, without requiring an oil or water cooling apparatus.

Abstract: A backup battery for buffering the operating voltage of a circuit arrangement is realized by a battery combined with an electrically irreversible element established by a melt fuse to form a unit. When the irreversible element exhibits its original condition when monitored, it is placed into the irreversible condition and the point in time is stored. As a result of the positive identification of the point in time of the initial commissioning of the backup battery, a premature replacement of the battery before expiration of the guaranteed service life that may appear necessary due to security considerations is avoidable. In a specific development, reaching the end of the service life of the backup battery is marked by the irreversible element.
