Abstract: A method for traffic-dependent control of beam projection of headlights of motor vehicles requires the passing of images from at least two image recording units to a control unit for evaluation. A road profile is generated as a three-dimensional image by reference to the images from the at least two image recording units so that predictive control of the vehicle lighting is carried out on a basis of the determined road profile.

Abstract: An illuminating device, particularly for motor vehicles, is suggested which has a housing, and a lens which form the interior space of a headlight. In addition to reflectors and lights, a component 15 is provided in the interior space of the headlight, which component 15 is arranged on the housing of the headlight and which has a heat-sensitive expansion element 16 and a valve 17, in which case the expansion element opens the valve when a defined temperature has been reached for the aerating of the interior space of the headlight. In addition, a moisture-absorbing material is arranged in the interior space of the headlight, which material absorbs the moisture in the headlight at low temperatures and thus when the valve is closed.

Abstract: A device is provided for controlling the light distribution of a headlamp installation of a motor vehicle, with a first light source for an additional lamp and a second light source for a driving lamp. In order to provide a better device for controlling(the light distribution of a headlamp installation of a vehicle, it is provided that a light source for an additional lamp be mounted so that it can swivel. In this process, the light source for an additional lamp will illuminate part of the vehicle's own lane lying outside the edge of the roadway, while, in its second position, it illuminates the vehicle's own lane, preferably at a greater distance. The light source for the additional lamp is mounted in such a way that it has, at least, one common light passage area with, at least, one other light source.

Abstract: This invention relates to a side lamp for vehicles which have an opening in their shell. In order to provide a side lamp which can be used as a turn signal side lamp and as a side marking lamp, it is suggested to construct the side lamp as part of an edge of an opening, preferably a wheel opening, on the shell of the vehicle. It is also contemplated to provide a reflector as a component of the side lamp which can be designed as part of a cover plate of the side lamp.

Abstract: An under-the-floor lathe for re-machining the wheels in railroad-vehicle wheel sets. It has two assemblies for each wheel in the set. Each assembly comprises an upright, a swiveling head, an axle-bearing support, a hold-down, two friction rollers that can be positioned against one of the wheels, and a friction-roller holder. At least one of the friction rollers in each holder is powered. Each holder rotates around an axis that travels along the mid-plane of the lathe. The object is to accelerate the machining action without using brakes that engage the friction-roller holders. Two pressure-application devices that generate opposite torques in relation to their associated pivoting axis are attached to each friction-roller holder.

Abstract: A below-floor lathe for reprofiling the rims of railroad-vehicle wheel sets, with four driven friction rollers, two rotating supports, and controls. The friction rollers can be forced in pairs against the outer surface of each rim in a wheel set. A detector determines the level of slippage that occurs between a friction roller and a rim surface and varies the rate at which the rotating supports advance in accordance with the level of slippage detected.

Abstract: For machining the tread circumferences and brake disks of sets of wheels dismounted from railroad vehicles a lathe is proposed wherein each wheel in the set is driven by four friction rollers that can be forced against the tread and are positioned essentially diametrically opposite one another in pairs.

Abstract: A tailstock sleeve guide for lathes comprising two axially spaced guide sleeves which guide the tailstock sleeve and are inserted into a bore of a housing. Adjustment of the radial guide clearance of the tailstock sleeve is effected by axially compressing the guide sleeves. Between the two guide sleeves (4, 5) a claming means (6) act thereon to minimize the time required for the adjustment of the two guide sleeves to identical guide clearance of the tailstock sleeve.

Abstract: An underfloor wheelset turning machine for reprofiling the wheel tire contours of railway wheelsets comprising two driven friction roller pairs each adapted to be pressed against a wheel tire contour of a wheelset, the friction rollers of each friction roller pair being individually connected in each case to a pivot drive and each pivotal about a pivot axis arranged parallel to the wheelset axle, is distinguished for uniform application of the friction rollers and automatic alignment of the wheelset axle in that each pivot drive (13, 14, 15, 16) comprises a pneumatic bellows cylinder (76, 77, 78, 79) for producing the pivot movement and that in each case two pivot drives (13, 14, 15, 16) associated with a friction roller pair (11, 12) are coupled to a synchronizing means (80, 81).
