  • Patent number: 8740189
    Abstract: A lifting system for vertical adjustment of a transportation system structure consists of a foot that is fastened onto the transportation system structure and a foot cradle. The foot is bounded on opposite sides by two foot surfaces that are arranged at a foot-surface angle to each other. The foot cradle has two complimentary supporting surfaces against which the foot surfaces rest. The supporting surfaces are vertically movable, allowing the foot and transportation system structure to be raised or lowered, and the vertical adjustment thereby takes place.

  • Publication number: 20130228414
    Abstract: An escalator or a moving walkway includes a support structure and a soffit plate. A first side edge region of the soffit plate is fixedly connected with the support structure. In addition, the soffit plate is biased between the first side edge region and a second side edge region, which is opposite the first side edge region, by a predetermined biasing force. In order to maintain the bias the second side edge region is fixedly connected with the support structure, wherein through the maintenance of the biasing force a stiffness of the support structure is increased and in operation of the escalator or the moving walkway the output of noise is reduced.

  • Patent number: 8461655
    Abstract: A method for manufacturing a micromechanical sound transducer includes depositing successive layers of first and second membrane support material on a first main surface of a substrate arrangement with a first etching rate and a lower second etching rate, respectively. A layer of membrane material is then deposited. A cavity is created in the substrate arrangement from a side of the substrate arrangement opposite to the membrane support materials and the membrane material at least until the cavity extends to the layer of first membrane support material. The layers of first and second membrane support material are etched by applying an etching agent through the cavity in at least one first region located in an extension of the cavity also in a second region surrounding the first region. The etching creates a tapered surface on the layer of second membrane support material in the second region.
