摘要： To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.

摘要： Apparatus for gathering particulate material in mines and similar plants has a mobile platform which collects particulate material and surrounds the trailing end of a material removing conveyor. The sides of the trailing end of the conveyor are flanked by plate-like carriers on each of which are fixed several beams serving to push gathered material toward and onto the conveyor in response to movement of the carriers toward the conveyor. The carriers are movable toward and away from the conveyor by motors which are installed beneath the platform, and the apparatus further employs stationary or reciprocable barriers, one behind each beam, which prevent the beams from pushing material away from the conveyor during return strokes of the carriers. Those ends of the beams and barriers which face in the direction of forward movement of the platform slope forwardly and downwardly to facilitate penetration beneath the accumulations of particulate material on the platform.
