Abstract: In a vehicle lamp, in particular a side marking lamp for a motor vehicle, comprising at least one light source and at least one optical system (6a, 6b) arranged in the beam path of the light source, the substantially conical light beam issuing from the light source impinges directly on the optical system (6a, 6b) and shines therethrough, wherein the optical system (6a, 6b) is such that it produces therefrom a cruciform light distribution (3).

Abstract: A bicycle dynamo with a rotary-current generator having a stator and a rotor which can be rotated relative to the stator. The stator or the rotor has radially extending pole fingers which are wound individually with one surrounding magnetic coil winding respectively. The ratio of the number of poles of the rotor to the number of poles of the stator is a non-integer value, and the ratio of the number of poles of the stator to the number of poles of the rotor is a non-integer value. This permits the implementation of a bicycle dynamo of a high efficiency even at a relatively low riding speed, which may be used, for example, to power bicycle lighting systems.

Abstract: In the production of hollow bodies from oriented thermoplastic material, a cylindrical portion of a heated hollow preform is stretched, with a simultaneous reduction in the wall thickness thereof, at a starting temperature below the vitreous transition temperature of the material. A mandrel is positioned in the preform to support it during stretching, the outside diameter of the mandrel corresponding to the inside diameter of the preform. Directly before the mandrel is inserted into the preform the preform is subjected to re-alignment to adapt at least the cross-sectional shape of the mouth opening of the preform to the cross-section of the mandrel. The re-aligning operation is effected by inserting the preform into a sleeve adjoining a drawing ring for carrying out the stretching operation.

Abstract: An apparatus for treating blanks of plastic material comprising a substantially cylindrical main frame structure, a central, coaxial cam drum which is mounted within same rotatably about its longitudinal axis and which is provided on its outside with working cams, and a plurality of treatment stations arranged in juxtaposed relationship around the periphery of the frame structure, with tools for processing the plastic blanks. The tools in a respective station are carried by vertically movable carriages, each of which is adapted to be moved up and down in the station by a cam follower guided by an associated cam on the cam drum. Each cam follower is carried by a drive carriage. The respectively associated tool carriages and drive carriages are each independently guided on the housing by vertical guide means and are interconnected by way of non-rigid connecting means.
