Abstract: Medical or dental instruments having a lighting device, manufacturing methods for such instruments and various lighting devices having an optical semiconductor element are described. The lighting devices have, for example, a body, at least one radiation-emitting surface on a radiation-emitting end of the body and at least one fluid channel which is provided in the body and connects at least one opening which is provided on the radiation-emitting end to one or more fluid sources for dispensing fluid. The lighting devices have, for example, a hollow metallic sleeve, a transparent window for emission of electromagnetic radiation and a socket on which at least one optical semiconductor element is arranged. The socket is made of a ceramic, glass ceramic or glass material, and is connected to the hollow metallic sleeve by a material comprising metal and glass.

Abstract: A medical or dental handle for driving a medical instrument, comprises a housing with a drive device accommodated therein and/or a supply line for a drive device, a first connection device for detachably connecting a medical or dental instrument and a second connection device for detachably connecting the handle to a media source and/or a drive unit, at least one electric component preferably comprising a light-emitting diode, at least one electric contact and an electric connecting device, which connect electrically the at least one electric component and the at least one electric contact, wherein the electric connecting device comprises a flexible circuit board in the interior of the handle.

Abstract: The invention relates to a long-range optical device (1), in particular binoculars, with a housing (2) and a support means, wherein at least one mount (3) is provided between the housing (2) and the support means for forming a mechanical connection, and wherein the at least one mount (3) comprises an interface for forming an electrical or electronic connection between the housing (2) and the support means.

Abstract: The device for forming a fabric edge from two doup ends and one stationary thread comprises three guides for the doup ends and the stationary thread. The doup ends are twisted by the device after every second weft thread insertion. The thread guides for the doup ends and the thread guide for the stationary thread are arranged to pivot towards each other to form a shed between the doup ends on the one hand and the stationary thread on the other hand. The thread guides take the form of two needles to guide the doup ends and one needle for the stationary thread The two needles for the doup ends are parallel and spaced apart through a rotary support in such a way that the needle for the stationary thread can penetrate between the two needles for the doup ends.
