Abstract: PCT No. PCT/SE97/01016 Sec. 371 Date Jan. 12, 1999 Sec. 102(e) Date Jan. 12, 1999 PCT Filed Jun. 11, 1997 PCT Pub. No. WO97/47441 PCT Pub. Date Dec. 18, 1997A robot arm comprises an assembly (6) rotatable relative to a part (2) of the arm about an axis extending at an angle to a longitudinal axis of the arm part, said assembly comprising a drive unit (8) and a member (9) driven by the drive unit. A cable (35, 36) comprising one or more lines for communication of energy for driving and/or control purposes extends between the arm part (2) and the drive unit (8). The assembly (6) comprises an axle pin (13) rotatably supported relative to the arm part (2). The cable extends in a space (48) provided in the assembly and comprising a first part space (49) provided in the axle pin (13), the cable being coiled in screw-line-shape in said first part space, and a second part space (50), in which the cable extends from the first part space (49) to the drive unit. The two part spaces (49, 50) are separated from each other in a sealed manner by means of a separation element (51) which has first sealing members for adjoining sealingly to a wall delimiting the space and second members for sealed passage of the cable.

Abstract: A line arrester, which is articulately suspended from a transmission or distribution network and on which a stabilizing device is arranged. The stabilizing device increases the mass-moment of inertia of the line arrester so as to contract movements of the line arrester deviating from the vertical line. The stabilizing device has a mass center which substantially conforms to a vertical line which passes through the mass center of the line arrester.

Abstract: A device for relative movement of two elements (1, 2) comprises two link arrangement (5, 6) coupled in series by means of a connection arrangement (4). A first link arrangement (5) comprises at least three links (9, 14), which have substantially equal length and which are substantially parallel, said links (9, 14) being oriented in a substantially triangular relation, viewed along the longitudinal direction of the links, between the connection arrangement (4) and the element (2). The second link arrangement (6) comprises at least one parallelogram acting between the connection arrangement (4) and the element (1). First the second force-applying arrangements (17, 18) are adapted to cause the first link arrangement (5) to pivot. A third force-applying arrangement (33) is adapted to cause the second link arrangement (6) to pivot.

Abstract: The magnetic circuit of a generator in a wind power plant is arranged to directly supply a high supply voltage of 2-50 kV, preferably higher than 10 kV. The generator is provided with solid insulation and its winding includes a cable ( 6 ) comprising one or more current-carrying conductors ( 31 ) with a number of strands ( 36 ) surrounded by at least one outer and one inner semiconducting layer ( 34, 32 ) and intermediate insulating layers ( 33 ). The outer semiconducting layer ( 34 ) is at earth potential. The stator winding may be produced with full or fractional slot winding, the phases of the winding being Y-connected. The Y-point may be insulated and protected from over-voltage by means of surge arrestors, or else the Y-point may be earthed via a suppression filter. The invention also relates to a wind power plant, a generator included in the plant and a variable speed system for such a plant.

Abstract: An equipment for controlling an industrial robot, which robot has a plurality of rotation and/or translation axles (ax 1-6), comprising a motor (15) at each of said axles for generating desired movements of the arms and/or the wrist, of which the robot is constituted, a sensor at each of the axles for measuring axle angle and/or axle position, a servo (9) for each of the axles for controlling the motors based on measurement values from the sensors, and a path generator (8) for generating at least one reference (phiref, phiref, tauffw) for each of the servos (9). The equipment comprises an apparatus (1+2+3+4+5+6+7+parts of 8+18A+18B) at least one of the axles, which apparatus comprises a first device (18A) for calculation of the expected interference moment value (taudistexp) of said axle when the movable parts of the robot is not exposed to any external forces by interaction with the operator (64) or other things in the surroundings of the robot, and a second device (18B) for comparing this expected interference moment value (taudistexp) with values of the moment reference (taumr) of the servo (9) and/or with values of the moment (taum) of the motor and/or with values of the moment of the axle (14) and for forming, based on this comparison, a signal (taucontrol) for controlling the path generator (8). A method for programming/adjusting the movement of a robot is also included.

Abstract: The present invention relates to a method for locating a fault on a power transmission line which is series-compensated with capacitors. The site of the fault is determined with the aid of measured currents and voltages at one of the two ends of the power transmission line before and after the occurrence of the fault and a calculating algorithm based on impedance models of the power transmission line before and after the occurrence of the fault.

Abstract: In a plant for controlling an equipment ( 4 ) adapted to carry out a process a superior arrangement ( 1 ) exists and has a first interface ( 2 ) to a programming unit ( 3 ) and a second interface ( 5 ) between the process equipment ( 4 ) and the arrangement. The arrangement has members ( 6 ) for transmitting information between the two interfaces. A memory member ( 9 ) adapted to store important data required for describing and defining the process of the process equipment is arranged in the process equipment itself. The arrangement ( 1 ) is provided with a rule data base ( 8 ) and a text data base ( 7 ) containing a configuration file for communication between the process equipment and the arrangement through the second interface by utilising a general process application protocol and a text file, respectively, adapted to the format of said data in the memory member of the process equipment.
