  • Method and means for the elastic bending of a support for a flexible switch
    Patent number: 6062144
    Abstract: A method and device for the elastic bending of a support (16) with at least one bendable end (24), intended in particular for a flexible switch (10). To achieve an elastic line of a finite radius of curvature also at the free end of the support, a bending moment diverging from zero is generated in the elastically bendable end (24) of the support (14) by applying a force coupling to an auxiliary lever (28).

  • Arrangement for controlled guidance of a wheel axle or of a bogie of a rail vehicle passing over points
    Patent number: 4925135
    Abstract: An arrangement is proposed for controlled guidance of a wheel axle (22) or of a bogie of a rail vehicle passing over points, whereby the wheel contact point (48, 50) is subjected to a controlled influence such that the wheel axle runs substantially vertical to the track longitudinal axis. The controlled influence of the wheel contact point can be exerted by, for example, the stock rail (32) veering away outwards in the area that the blade begins.
