Abstract: A rotor blade for a flow machine, in particular a steam turbine, includes an insertion root with a first finger and two second fingers which are arranged on either side of the first finger in axial direction. The first finger and the second fingers have a shoulder in axial direction on axial sides facing one another such that the fingers have a radially outer first portion and a radially inner second portion whose axial extension is shorter than that of the outer, first portion. In relation to a total axial width between axial sides of the two second fingers which face away from one another, the radial height of the first, radially outer portion is in the range of 0.39 to 0.45, particularly 0.40 to 0.44, and the radial height of the second, radially inner portion is between 0.40 and 0.46, particularly between 0.41 and 0.45.

Abstract: Method and an automation component for setting the clock frequency of a microprocessor in an industrial automation arrangement, the clock frequency of the microprocessor being selected depending on a required computation power, wherein in a first step, the required duration for execution of the main program cycle of a control program running on the automation component is detected, in a second step, this duration is compared with a maximum value, and in a third step, a new clock frequency is determined depending on the result of the comparison and used for the microprocessor. The method and automation component make it possible to match the clock frequency of the microprocessor dynamically, wherein firstly, the required computation power is always provided, and secondly an unnecessarily high clock frequency is avoided. As a result, a corresponding saving on energy and reduction in the power losses can be achieved.

Abstract: In a method for robot-controlled cutting of workpieces to be joined by laser radiation, a first workpiece is arranged in vicinity of a second workpiece in a first position. A laser is focused onto the first workpiece. A contour of the first workpiece is cut with the laser beam; this contour is to be assembled and joined with the second workpiece. During cutting, a first spacing of a focal point of the laser beam from the second workpiece is repeatedly determined in a distance direction that is identically oriented during cutting and is adjusted to a direction of assembling the first and second workpieces. During cutting, a second spacing of a processing point of the laser beam from the second workpiece is maintained at a constant value.

Abstract: A rotor of a steam or gas turbine is equipped with rotor blades, which are held in the rotor (6) in a plurality of radial rows and comprise a blade foot 1 installed in the rotor (6), a blade leaf (2) and a cover plate (3). An open pocket (5) is prepared in the sloping surfaces of the cover plates (3) of a row of rotor blades, which the sloping surfaces are located opposite each other. The pockets (5) of two adjacent cover plates (3) form together an essentially closed cavity, which expands in the radial direction of the rotor (6). A pin, whose largest cross section is smaller than the largest cross section of the cavity but larger than the smallest cross section of the cavity, is placed freely movably into each cavity.

Abstract: A connector (10) is connected to the front end of a cable (11) in a compact connection that provides electrical shielding and a water-tight seal. The connector has a metal main sleeve (30) with a rear end (64) having circular crimps (38,39). One crimp (39) is made against the cable insulator (16) to provide a water-tight seal and the other (38) is made to the cable shielding braid (35) to ground the main sleeve. The main sleeve has a front portion with a crimp (37) that crimps against an elastic seal ring (25) lying in a groove (23) in an insulative body (20) that has contact-holding passages (60).

Abstract: The laser beam optics for a robot link, wherein a first beam path of a first working laser beam is arranged on the longitudinal axis of the robot link, the first beam path is deflected at an end facing a workpiece into an axis-parallel second beam path, and a third beam path of a second working laser beam is axis-parallel to the first beam path in the robot link, have two optical elements arranged successively in one of the first and second beam paths of the first working laser beam. The two optical elements are transmissive for the first working laser beam in a transmission direction toward a workpiece and are adjusted relative to one another so as to compensate laser beam displacement of the first working laser beam. The second optical element arranged downstream receives the second working laser beam and reflects it toward the workpiece.

Abstract: A manipulator includes a carriage, a base and a longitudinal guide for positioning the carriage. The longitudinal guide contains two guide parts attached to the base to provide a sliding mount for the carriage along an axis. A spindle is coupled to the carriage for moving it longitudinally and is provided with a rotating mount on the base. The manipulator also includes two wedge arrangements between the side parts of the base and the guide parts of the guide to center the carriage and prestress the guide parts in the direction of the axis. Each wedge arrangement comprises two cooperating slant faces one of which is an inner face of each side part of the base and the other of which belongs to a wedge which is moved with respect to the respective guide part for centering the same relative to the spindle. After completion of the centering operation the guide parts will be secured to the base, e.g. by screws.
