Abstract: An apparatus (1) for the accurate centrical placement of a self-adhesive label (12e) onto a disk-shaped object (11), particularly a compact disk (11a), comprising a first housing part (2) provided with a locating device (4) for the label (12e), as well as a second housing part (3) provided with a locating device (3b) for the disk-shaped object (11), whereby the housing parts (2, 3) are connected with each other to swivel about a common swivel axis (C) and are conveyable from an open position into a closed position such that, in this closed position, the locating devices (3b, 4) are placed in a position arranged to face one another and that, in this closed position, at least one of the two locating devices (3b, 4) is movably arranged in the respective housing part to move in the direction toward the opposite locating device, in order to bring the disk-shaped object (11) into contact with the label (12e). The labels (12e) are adaptedly structured according to the apparatus (1).

Abstract: A bicycle lighting system comprising a dynamo generator, integrated rechargeable batteries and an integrated electronic circuitry, the bicycle being an exemplary embodiment of pedal-driven vehicles provided with standard front and rear lamps. Hitherto known systems operate with conventional dynamos having an efficiency far too low to provide power to energize lamps and simultaneously charge batteries at speeds below 15 kmph. The inventive generator is constructed such that a rotating magnetic-circuit arrangement with a stationary air-core coil and specially defined pole shoes achieve 90% efficiency. At 5 to 7 kmph, at least 4 W energy is available for energizing lamps and rapidly charging batteries. From standstill to approximately 5 kmph, the batteries energize the lamps.

Abstract: The tail light comprises several light emitting diodes used as light sources. At least one of these diodes generates light emitted into a backward direction. The other diodes are emitting light into lateral and upward directions. For this purpose an arrangement of reflecting surfaces deflects part of the light of the diodes upwardly. In this way it is possible to reach a required light distribution at a considerably reduced power consumption.

Abstract: An electric machine within a hub housing rotatably disposed on an axle. A magnetic rotor is mounted on and can be rotated about the axle and is driven by the rotation of the hub housing by means of a transmission. The magnetic rotor comprises a central support carrying a plurality of axially aligned permanent-magnetic rods arranged in a star-shaped configuration. A coil assembly in the form of a cylindrical shell is arranged around the magnetic rotor. This design results in a compact and easy to assemble configuration with an overall efficiency higher than 0.5.

Abstract: The bicycle light plant includes a front light and a rear light having a set rated voltage, which lights are connected via a current circuit to a dynamo. The current circuit includes a switching controller which lets the voltage of the dynamo pass uncontrolled if it is below the rated voltage of the bulbs and stabilizes the voltage upon reaching or exceeding, the rated value practically without losses onto voltage level corresponding to this rated value. Accordingly, overvoltage at the bulbs can be prevented. Possible excessive output is not taken from the dynamo or is used for charging of batteries.

Abstract: The headlight has a light ray guiding disk which is domed towards the source of light. This light ray guiding disk is structured as integral formed article and includes at its central zone, which has the smallest distance from the source of light, a collective lens structure. By means of this a substantial portion of the light rays emitted from the source of light into a spatial angle in front of the source can be focussed in the direction of the axis of the headlight. The light ray guiding disk can be manufactured as simple formed article. A transparent ring in a signal color is foreseen outside the light ray guiding disk. By means of this disk the stray light is utilized for a lateral marking when the headlight is used e.g. in a bicycle lighting arrangement.
