Abstract: An elevator installation has a sealing element that is movable by an electromagnetic actuator from a first position to a second position. The sealing element includes a seal carrier that is movably arranged at a door leaf of a door of the elevator installation. An electromagnetic actuator is fastened in the region of the door and upon actuation acts on the seal carrier to move it from the first position to the second position. An electrical circuit triggers the actuation before the door leaf executes an opening movement.

Abstract: A wall plate for use in an elevator installation has a glass part divided into segments, the transparency of which is individually controllable with physical magnitude information signals. A control device is connected to the segments for controlling the transparency on the basis of qualitative and quantitative state information and by linking the state information with the controlling magnitude information signals.

Abstract: A compactly constructed guide system has a run surface for guiding the run of the chain rollers. To guide the sides of the steps, a sliding pin arranged on a step rests on a side surface. A counter-surface serves as a counter-guide for the chain rollers and prevents the chain links from being pushed together. By means of an encapsulation, the step rollers, the chain links, and the running surface can be protected from dirt, dust, water, objects, etc. For run guidance of the step roller, a running surface is provided. An oil collecting channel prevents dripping of lubricating oil. The guide system rests on a bracket plate projection and is releasably connected to the bracket plate. The single-piece guide system is simple and efficient to install and can be accurately positioned at the sides against stops.

Abstract: An escalator or moving walk has a truss that is supported in the area of its extreme ends. In the area between its two extreme ends, the truss has at least one tension element which, at a first end, is connected mechanically to the truss, and at a second end is connected to a fastening point. The tension element is constructed and tensioned such that it exerts a tensile force on the truss that acts at least partly in the direction of the earth's gravitational force.

Abstract: A method for designing a regulator uses a predetermined overall model of an elevator car with known structure. The model parameters are known to greater or lesser extent or estimations are present, wherein the parameters for the elevator car used are to be identified. In that case the frequency responses of the model are compared with the measured frequency responses. With the help of an algorithm for optimization of functions with numerous variables the estimated model parameters are changed to achieve the greatest possible agreement. The model with the identified parameters forms the basis for design of an optimum regulator for active vibration damping at the elevator car.
