  • Publication number: 20210020979
    Abstract: According to the invention, an electrolyte is provided for an alkali-sulfur battery. An alkali-sulfur battery is also provided, which contains the electrolyte according to the invention. The electrolyte according to the invention contains a mixture of a sulphone and a fluorine-containing ether in a volume ratio of #1:4 (v:v). Through the use of said electrolyte, the shuttling of polysulphide species from the cathode to the anode can be effectively suppressed, without the use of LiNO3. Through the electrolyte in alkali-sulfur batteries, a high coulombic efficiency, long-term stability (low self-discharge) and cycle durability can be achieved even without the use of LiNO3. Coloumbic efficiency, long-term stability and cycle durability can be further improved through the use of a cathode which contains an additive for uniform distribution of polysulphide inside the cathode. In addition, uses of components of the alkali-sulfur battery according to the invention are also disclosed.

  • Publication number: 20210008662
    Abstract: A laser beam is directed onto a pyramid-shaped element, wherein the beam is directed onto at least three reflecting surfaces and the respective reflected partial beams are incident on reflecting surfaces arranged on an optics carrier element. The partial beams are aligned such that they intersect in a common plane. An internal wire feed is arranged in a housing, having an outlet nozzle for a fusible wire-shaped material, which material is using the energy of the partial beams. The outlet nozzle is arranged in front of the plane in which the reflected partial beams intersect. The pyramid-shaped element and the reflecting surfaces are formed on a carrier element, which is arranged in such a way that it is displaceable following the outlet nozzle in two perpendicular directions to the optical axis of the laser beam or perpendicular to the central longitudinal axis of the wire-shaped material.

  • Patent number: 10887610
    Abstract: Transform block coding is performed very efficiently in terms of computational complexity and compression ratio, by coding the magnitude bits of the transform coefficients distributed in a matrix, in which the magnitude bits of the spectral coefficients are arranged column-wise with the spectral coefficients of the transform block ordered along a row direction of the matrix. That is, magnitude bits within a certain column of the matrix belong to a certain spectral coefficient, while magnitude bits within a certain row of the matrix belong to a certain bit plane. In this configuration, the distribution of non-zero magnitude bits may be condensed towards one corner of the matrix, corresponding to, for instance, the least significant bit plane and corresponding to, by using a scan order among the transform coefficients which sorts the transform coefficients generally in a manner from lowest to highest frequency, the lowest frequency. Various low complexity variants are presented.

  • Publication number: 20200398374
    Abstract: The invention concerns a method and an apparatus for processing an object (1) by means of interfering laser beams. It is the task of the invention to provide for an improved compensation of the aberrations accumulated over the beam path in such processes/apparatuses, since these are a substantial disturbing factor with respect to the precision in structuring the material. Furthermore, the influence of the period course, i.e. the spatial modulation of the period of the modification produced in the material of the object (1), shall be improved. The invention proposes that laser radiation is generated as a collimated laser beam (3). The intensity distribution and/or the phase progression is influenced over the cross-section of the laser beam (3) to correct aberrations. The laser beam (3) is divided into two partial beams (6, 7). Finally, the partial beams (6, 7) are deflected and focused so that the partial beams (6, 7) overlap in a processing zone (10) in the material of the object (1).
