Abstract: A rope brake for an elevator installation for braking a rope coupled to a car is provided, which has a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe. The rope is led between the stop and the brake shoe, and the brake shoe is adapted to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope. A drive coupled to the brake shoe is provided for releasing the rope. The drive is formed as a linear drive and the at least one brake shoe can be transferred by means of the linear drive into its release position against the action of a braking force acting on it in the braking position. Methods for testing a rope brake for an elevator car having a movable brake shoe are also provided.

This antenna array can be connected with at least one reader. There can be at least one antenna consisting of an antenna loop having at least one winding. The antenna array can include at least two antennas that are disposed in a plane, in such a manner that the antenna loops of the individual antennas overlap. With this design, at least one multiplexer can be disposed between the at least one reader and the antennas of the antenna array, for selected activation of the antennas.

Abstract: The invention relates to an oblong signal strip (1), comprising signalling sections (2, 3) along the longitudinal extent thereof, each comprising at least two different pieces of information, referring to an optical property, a magnetic property or a property relating to a reflection of electromagnetic waves from the signalling section (2, 3), as determined by at least one sensor device (7-9). Information relating to the same property in alternating signal sections (2, 3) are different from each other. The signal strip (1) is applied to a system for determining a movement status of a moving body, in particular, a car (6) of a lift system (4).

Abstract: The invention relates to an elevator system with at least one shaft, in which at least two cars can be made to travel along a common traveling path, and also with a shaft information system for determining the positions and speeds of the cars, which is connected to an electrical safety device.

Abstract: An elevator installation with at least one shaft having a plurality of shaft doors is provided. At least two cars disposed one above the other travel up and down in the shaft. Each car has at least one car door. A safety device is provided for blocking the travel of the cars when the shaft doors or car doors are open. The safety device has at least two independent safety circuits, each having at least one shaft door and/or car door associated with it. Travel of at least one car can be blocked by means of the safety circuits.

Abstract: The invention relates to an elevator installation with at least one shaft, in which at least two cars disposed one above the other can be made to travel up and down, the shaft having a plurality of shaft doors and the cars respectively comprising at least one car door, and with a safety device for blocking the travel of the cars when the shaft doors or car doors are open. In order to develop the elevator installation in such a way that its transporting capacity can be increased and the cars hinder one another as little as possible, it is proposed according to the invention that the safety device has at least two independent safety circuits, each having at least one shaft door and/or car door associated with it, it being possible for the travel of at least one car to be blocked by means of the safety circuits. A method for controlling an elevator installation is also proposed.

Abstract: The invention relates to a rope brake for an elevator installation for braking a rope coupled to a car, with a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe, it being possible for the rope to be led through between the stop and the brake shoe, and it being possible for the brake shoe to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope, and with a drive coupled to the brake shoe for releasing the rope.

Abstract: An elevator system is provided for the transport of loads and/or persons in an elevator shaft. At least two elevator cars can be moved in the elevator shaft and are connected to a counterweight. A drive is associated with each car. At least one common track section and, in addition, separate track sections arranged next to one another are associated with at least two cars. The common track section and the separate track sections are arranged in sections along the elevator shaft. The cars can be moved not only in the same direction but also in directions opposite to one another.

Abstract: A two-wire bus system for connecting a plurality of users has at least one damping circuit for damping line resonances in the two-wire bus system with respect to a reference potential. The damping characteristic of the damping circuit is selected such that the damping only becomes operative above a preestablished reference voltage threshold1 value. In this manner, it is achieved that a useful signal is not weakened by the damping circuit, but rather resonance voltages are damped only above the threshold value. It is advantageous if each of the users of the bus system has assigned to it a damping circuit.

Abstract: The invention relates to an elevator system for the transport of loads and/or persons in an elevator shaft with at least two elevator cars which can be moved in the elevator shaft and are connected to a counterweight via carrying means, wherein a drive is associated with each car. In order to develop the elevator system further in such a manner that it can be produced inexpensively and has an improved transport capacity it is suggested in accordance with the invention that at least one common track section and, in addition, separate track sections arranged next to one another be associated with at least two cars in sections along the elevator shaft, wherein the cars can be moved not only in the same direction but also in directions opposite to one another.

Abstract: A glue coating apparatus is provided having a plurality of individual slit nozzles. Two faces are formed by an end face of a nozzle plate, in which feed channels open out, and by a clamping strip extending in front of the nozzle plate, these clamping a slit plate between them. The feed channels open into the regions of the slit plate which remain free between webs, so that the glue is channeled through the back of the slit plate. The webs and the individual glue streams are combined only immediately in front of an outflow point, to assure a uniform covering of the coating width, but prevent an overflow of glue from one slit nozzle into an adjacent one. The webs may also be tapered towards the outflow point, so that the individual glue streams can easily merge into one another.

Abstract: A glue coating apparatus is provided having a plurality of individual slit nozzles. Two faces are formed by an end face of a nozzle plate, in which feed channels open out, and by a clamping strip extending in front off the nozzle plate, these clamping a slit plate between them. The feed channels open into the regions of the slit plate which remain free between webs, so that the glue is channeled through the back of the slit plate. The webs and the individual glue streams are combined only immediately in front of an outflow point, to assure a uniform covering of the coating width, but prevent an overflow of glue from one slit nozzle into an adjacent one. The webs may also be tapered towards the outflow point, so that the individual glue streams can easily merge into one another.
