  • Patent number: 7407173
    Abstract: A motor vehicle chassis structure which includes an independent suspension system including left and right suspension components for left and right wheels (4, 8) respectively for gripping and travelling along a road surface, each of which suspension components is arranged to allow a constrained up and down movement of the respective wheel relative to the vehicle chassis structure, characterised in that the upper suspension components on one side of the vehicle are cross-linked with the upper suspension components on the other side of the vehicle by a connecting rod (10, 11) and an offset pivot shaft assembly (9, 5), so as to constrain the plane of each wheel towards an orientation which is normal to the road surface while allowing the chassis structure to move vertically and to roll relative to said wheels during cornering, acceleration, deceleration and combinations thereof.

  • Patent number: 7402024
    Abstract: A steam turbine (20), in particular for high pressure and/or intermediate pressure applications, has a rotor (11), which can rotate about an axis (23), an inner casing (14), which concentrically surrounds the rotor (11) at a distance, so as to form an annular passage (12) extending in the axial direction, and an outer casing (13), which concentrically surrounds the inner casing (14) at a distance so as to form an annular intermediate space (16) extending in the axial direction, blading including rotor blades (21) and guide vanes (22) being provided in the annular passage (12), and the annular passage (12), on the outlet side, being in communication with the intermediate space (16) in order for the steam to be passed on, and the inner casing (14) also being externally surrounded by a plurality of shrink rings (15), which are arranged one behind the other in the axial direction and project into the intermediate space (16).

  • Patent number: 6144208
    Abstract: A method for identifying and/or differentiating between asbestos materials and aramid materials comprises the steps of rubbing an area of a surface of a material (44) to be identified, with an acrylic reference material (28), measuring the polarity of the generated electrostatic charge and comparing the polarity with polarities of charge generated from surfaces of known asbestos and aramid materials.
