An industrial robot has two linkages connected with a rotary joint. Gravity imposes a torque on the joint. A counterbalancing unit connects the two linkages to each the other to compensate for the gravity-caused torque. The unit has a cylinder with two chambers. A piston in the cylinder has one end connected to the rotary joint and seals the two chambers against each other. Hydraulic fluid is in at least one of the two chambers and one or more instances of compressible material are in the hydraulic fluid. Movement of the rotary joint in a predetermined direction causes the piston to move and compress the compressible material and increase the cylinder pressure to create a force on the piston rod in a direction opposite to a direction of the piston movement.

METHOD AND APPARATUS FOR THE PROTECTION OF DC DISTRIBUTION SYSTEMS
While transient current magnitudes at different locations within a DC distribution system themselves are not a reliable indicator of fault location, it is recognized herein that accumulating energy or pseudo energy values provides a reliable basis for tripping the protection element at a fault location. Thus, in one aspect of the teachings herein, pseudo energy values are accumulated independently during a fault condition, for each of one or more protected branch circuits and the protection element for each such branch circuit is tripped responsive to the accumulated pseudo energy values reaching a defined pseudo energy threshold. The pseudo energy thresholds are defined so that the protection element in the branch circuit where the fault is located will trip first.

A wind power generator comprising a stator, a rotor with a shaft connectable to wind turbine and a stationary superconducting coil structure for magnetizing the rotor of the wind power generator, the stator of the wind power generator comprising a multi-phase winding for producing electricity from the wind power generator. The wind power generator is a synchronous generator, and the superconducting coil structure comprises end portions that are arranged to be magnetized with opposing polarities by a superconducting coil, and the rotor comprises poles ex- tending in the surface of the rotor in the direction of the shaft of the generator, the poles being arranged to be magnetized using the superconducting coil structure, wherein each rotor pole is arranged to extend inwardly at one end of the pole such that the inwardly extended end of the pole is arranged in the vicinity of an end portion of the superconducting coil structure for magnetizing the rotor pole and wherein the rotor poles comprises pole shoes, which are formed to provide sinusoidally varying air gap flux in the air gap between stator and rotor.
