Abstract: A signaling device, in particular a signal pillar 1, is provided which is able to generate signals even outside the range of the usual optical and acoustic signals, and flexibly create them as needed with little additional effort. This object is achieved by providing a wireless transmitting unit (8) for transferring data to a receiver in addition to the signal elements (2, 3, 4) for generating optical and/or acoustic signals, wherein the transmitting unit (8) is arranged in an exchangeable module.

Abstract: A signaling appliance is provided, in particular a signaling column for indication of at least one operating state of a technical appliance such as a machine, an installation, a vehicle or the like, having at least one holding apparatus (5) for holding an electrical light-emitting element, in particular an incandescent lamp, which can be produced at a lower cost and/or provides further application options, in which case the electronics mount can be installed very easily, for example for commercially available signaling elements and/or bulbs. According to the invention, this is achieved in particular in that the holding apparatus (5) which is provided for holding the electronics mount (9) is also designed to hold the signaling element (7), with the holding apparatus (5) having at least one guide apparatus (8) for lateral guidance of the electronics mount (9) to be installed.

Abstract: A signal apparatus is disclosed which permits flexible use of the individual signal apparatus components. According to the invention, a holder and a signal generator for the connection to the holder are provided. The signal generator includes a base housing made of plastic and penetrated by at least two contact elements, and the function elements of the signal apparatus.

Abstract: An illuminator, in particular for a signal lamp, having at least one LED which is mounted on an LED printed circuit board is provided which permits uncomplicated and flexible production. A base housing of the illuminator is produced from plastic. The base housing is penetrated by at least two contact elements.

Abstract: A signal generator is suggested for a mounting on holding tubes, having a base element for being placed on the holding tube and a fastening element for fixing the base element on the holding tube, which requires low expenditures during the manufacturing and ensures a reliable fixing. According to the invention, this is achieved in that the fastening element cuts form-lockingly into the material of the holding tube (4) and of the base element (1).

Abstract: A method is described to contactlessly measure the brake temperatures of passing railroad cars, whereby the temperatures of all current practical brake types, for instance shoe and disk brakes at the wheels, but also of separate brake disks, can be measured. The method is characterized by using a known measurement apparatus with optics followed by an infrared sensor, whereby the measurement axis of this apparatus scans the passing wheel at a height 1 to 5 cm above the rail surface, the measurement axis "looking" from the rear-bottom, namely at an anagle alpha to the horizontal of 10.degree. to 22.degree. and at an angle omega of 7.degree. to 18.degree. to a horizontal line which is perpendicular to the rails, on the wheel. The measurement apparatus is controlled by track switch means activating the apparatus as long as the wheel rolls through the measurement axis.

Abstract: The invention concerns a system to detect irregularities in the geometry of railway wheels. The system is characterized in that a linearly expanding accelerometer is solidly joined to the rail underneath its head. The accelerometer sensitivity is constant over its entire length and generates a voltage proportional to the acceleration of the rail. For different damages, the rail acceleration takes place in different directions, whereby the voltage amplitude, depending on the type of damage, evinces opposite polarities. Frequency filtering or frequency analysis permit the determination of further criteria which, together with other weighted criteria, are used to characterize wheel damage.
