20150122377 | Steel, Sheet Steel Product and Process for Producing a Sheet Steel Product - The invention relates to a steel and to a flat steel product produced therefrom that have optimized mechanical properties and at the same time can be produced at low cost, without having to rely for this on expensive alloying elements that are subject to great fluctuations with regard to their procurement costs. The steel and the flat steel product have for this purpose the following composition according to the invention (in % by weight): C: 0.11-0.16%; Si: 0.1-0.3%; Mn: 1.4-1.9%; Al: 0.02-0.1%; Cr: 0.45-0.85%; Ti: 0.025-0.06%; B: 0.0008-0.002%, the remainder Fe and impurities that are unavoidable for production-related reasons, which include contents of phosphorus, sulfur, nitrogen or molybdenum as long as the following respectively apply for their contents: P: ≦0.02%, S: ≦0.003%, N: ≦0.008%, Mo: ≦0.1%. Similarly, the invention relates to a method for producing a flat steel product that consists of a steel according to the invention. | 05-07-2015 |

20090141346 | TELESCOPE WITH VARIABLE MAGNIFICATION - A description is given of a telescopic sight with variable magnification, comprising a fixed objective and first image plane assigned thereto, a variable system with second image plane assigned thereto, and a fixed eyepiece for viewing the second image plane and that has a stop in the vicinity of the first image plane whose aperture diameter can be varied as a function of the magnification of the variable system in order to suppress scattered and/or false light. | 06-04-2009 |
20110228395 | APPARATUS FOR ILLUMINATING A RETICLE - An apparatus for illuminating a marking, which is applied on a transparent reticle in the form of a diffraction structure, wherein illuminating beams are injected into the reticle via a side edge surface of the reticle such that they are emitted after diffraction at the marking perpendicular to the plane of the reticle, wherein a concavely curved mirror having two focal points is attached to the side edge surface such that a light source is arranged in the region of the first focal point and the marking is arranged in the region of the second focal point, wherein a second mirror having two focal points is attached such that a second light source with a second emission wavelength is arranged in the first focal point thereof and the marking is arranged in the region of the second focal point of the second mirror. | 09-22-2011 |
