Abstract: The aim of the invention is to improve a projector lens, comprising an optical element for shaping radiation fields emitted from light guides, such that the light guide may be optimally coupled to the optical element. Said aim is achieved, whereby the optical element is embodied in a monolithic body, comprising a radiation field forming region and a connector region for the light guide, which form part of the optical element and the connector region comprises a connector surface for a front face of the light guide which approximately matches a diameter of the light guide and is arranged offset from a vicinity of the connector region.

Abstract: A plug for light wave conductors or photo-conductors with a plug housing into a rear end of which a photo-conductor bundle with at least two photo-conductor fibers is introduced, and from an oppositely lying front end of which there emerge ferrules, into which, in each case, one of the photo-conductor fibers is introduced. The ferrules are supported in a ferrule housing which is installed in a plug housing correspondingly formed for the reception of the ferrule housing. The ferrules are movable, spring-loaded in their axial direction, in which the plug is intended for being plugged together with a coupling housing that receives this plug. The ferrule housing comprises a core housing and a core interior housing, which are designed for the reception of two ferrules. The ferrules are supported in the core housing. Front ends of the ferrules extend forward through the core housing and rear ends of the ferrules extend into the core interior housing.

Abstract: Alternate support for a drawing die made of hard metal, in which the drawing die is held with a hollow clamping ring which clamps the drawing die and the support, the drawing die being supported by a shoulder in a bore provided in the support. The drawing die is swingingly supported on the shoulder within the support.
