    摘要: A two-wheeled running gear for a track-guided vehicle comprising a running gear frame; a wheel carrier; first and second wheels coupled to opposite sides of the wheel carrier; first and second vertical pivot pins, the first vertical pivot pin coupled to the first side of the wheel carrier and movably connected to the first side of the running gear frame, the second vertical pivot pin coupled to the second side of the wheel carrier and movably connected to the second side of the running gear frame, the first and second wheels located between the first and second vertical pins; and means for controlling a movement of the first pivot pin relative to the running gear frame such that, during a curved track drive, the first pivot pin can be held substantially in place relative to the running gear frame while the second pivot pin can move relative to the running gear frame so that the line connecting the centers of the wheels is maintained substantially parallel to the radius of curvature of the track.

    摘要: A ball valve for shutting off pipelines carrying liquid, gaseous and solids-laden media, particularly those of large nominal diameters, includes a housing containing a ball provided with at least one bore and supported in a rotatable fashion in the housing by means of a spindle, annular seals located before and after the ball in the direction of flow in the housing which seal off the inlet side from the outlet side, one additional annular seal which rests upon the surface of the ball in the housing in each of the planes perpendicular to the spindle axis above and below the bore, as well as above and below the seals which are placed before and after the ball in the flow direction, in such a way that each of the planes which are spanned by them and are parallel with each other is perpendicular to the planes spanned by the sealing rings placed before and after the ball.
