Abstract: A wheel suspension system for a motor vehicle has a steering swivel (1) attached to a beam (3) so as to be rotatable about a vertical axis (6). The vertical axis (6) runs approximately through the center (Z) of the wheel. The beam (3) is additionally coupled at its lower end to the bodywork via a link (8), the link (8) being swivelably mounted on the bodywork. Instead of the steering swivel (1), it is also possible to mount a spindle so as to be rotatable about a vertical axis through the center of the wheel. The suspension leg (4) is secured against rotation by coupling to a stabilizer (20).

Abstract: This invention relates to a spouted bed wood chip debarker/cleaner. Such structures of this type, generally, cause wood chips and bark to undergo attrition by accelerating the wood chips and bark with a jet of air. In particular, the accelerated wood chips and bark are impinged on a screen. When the wood chips hit the screen, bark and wood chips experience attrition. Small pieces of bark and other debris (sand, for example) will be exhausted through the screen which is too fine of a mesh to let desirable size wood chips be exhausted.

Abstract: This invention relates to an apparatus and method for identifying periodic roughness variations on a paper surface. Such devices of this type, generally, collect topography data from the paper surface, analyze the data, and compare the data with known signature topographies of paper machine clothing and equipment to determine the location in the paper manufacturing process where the periodic roughness variations on the paper surface are being produced.
