Patent EP-0447639-A1 (EP)
Inventor: KUKE ALBRECHT DR RER NAT
IPC: G02B6/42
Filed: 1990-12-13
Abstract: In designing optical modules having more than one light-guiding path, the problem frequently arises of leading the light-guiding paths of a first functional unit having narrow spacings between the light-guiding paths to a second functional unit having wide spacings between the light-guiding paths, the spacings of the light-guiding paths needing to be fanned out. To date, use has been made for the light-guiding paths of optical waveguides having an S-shaped curvature or doubly bent straight optical waveguides. Emission losses occur with curved or bent optical waveguides. Moreover, the space required for a fan-out unit with curved light-guiding paths is large. According to the invention, the required parallel offset is achieved using straight optical waveguides (41-46), the end faces of the optical waveguides being inclined with respect to the axes of the optical waveguides. The required deflection of light is effected not by curvature of the light-guiding paths, but by optical refraction at the end faces of the optical waveguides (41-46), which are mounted on a baseplate (3).   Application: optical transfers, for example from directional couplers to fibre arrays or to lines of microoptical imaging components. <IMAGE>

Abstract: The rail vehicle contains a vehicle body and two bogies (4) which each have two wheel sets (5, 5a) with axles (6, 6a), which can be adjusted at least approximately radially with respect to a curve to be travelled through and mounted in axial bearings (7), and a bogey frame (8) which is supported on the axle bearings (7) via support elements which are resilient at least in the longitudinal direction of the bogey. The axles (6, 6a) are additionally each mounted in a guide part (16 and 16a, respectively) and coupled to the vehicle body via connecting means which are suitable for transmitting pulling and/or braking forces, which means comprise, per bogey (4), in each case a single longitudinal connecting element (37) which is coupled in a spatially moveable manner to the vehicle body and to one of the guide parts (16) and two hitch-like connecting parts (17 and 17a) which are rigidly connected in each case to one of the guide parts (16 and 16a). The connecting parts (17 and 17a) are coupled to one another so as to be swivellable in a spatially moveable manner and are supported on a support part (12) of the vehicle so as to be capable of sideways deflection. In accordance with this, the stressing of the bogey frame (8) by the pulling and/or braking forces is avoided and the radial adjustment of the wheel sets (5 and 5a) is made easier. <IMAGE>
