  • Patent number: 10926782
    Abstract: A strain gauge arrangement for an axle counter has a strain sensor element, a carrier and a railway line structure that is to be monitored. At least one part of the carrier is maintained in an elastically deformed state by the structure when the carrier is secured to the structure. The carrier is formed from a first carrier piece and a second carrier piece, which lie opposite one another at a distance from one another. The strain sensor element has one first fixing point fixed to the first carrier piece, and one second fixing point fixed to the second carrier piece, and a middle section mounted between the fixing points which are not fixed to the first or second carrier piece. The strain gauge arrangement is simple to handle and a drop can be reliably detected and a strain state of the strain sensor element can be predetermined more easily.

  • Publication number: 20210003057
    Abstract: A method for operating a petrol engine, in which air is introduced into an exhaust tract through which exhaust gas from the petrol engine can flow, bypassing the petrol engine, includes introducing the air into the exhaust tract at a point arranged downstream of a first three-way catalytic converter arranged in the exhaust tract and upstream of a second three-way catalytic converter arranged in the exhaust tract downstream of the first three-way catalytic converter, while the petrol engine is operated with a sub-stoichiometric combustion air ratio, where a desulphurization of the second three-way catalytic converter is effected.

  • Publication number: 20200363347
    Abstract: An X-ray detector device for a device for the X-ray inspection of products includes a first line detector with a first discrete spatial resolution, a second line detector with the same or lesser second discrete spatial resolution, and an evaluation and control unit. The first line detector is operable to capture X-radiation in a non-spectrally resolved fashion along a first capture line transverse to a product movement direction to generate first image data. The second line detector is operable to capture the X-radiation in a spectrally resolved fashion along a second capture line parallel to the first capture line to generate second image data. The evaluation and control unit is operable to evaluate the first and second image data to detect at least one predefined feature of the product with the first discrete spatial resolution by combining the items of information contained in the first and second image data.

  • Publication number: 20200231194
    Abstract: A method of mounting a rail monitoring member/element at a mounting location of a rail for rail traffic, in particular on a railway track, is disclosed. The rail monitoring member includes a strain sensor member with a carrier on which a strain gauge, being an optical fiber with a fiber Bragg grating, is fixed. The method steps include: determination of the temperature of the rail and/or rail monitoring member at the mounting location; checking whether the determined temperature is within a predefined temperature interval; providing heating or cooling application to the rail and/or rail monitoring member at the mounting location, if the determined temperature is not within the predefined temperature interval; positioning and adhesively fixing of the carrier of the rail monitoring member at the mounting location. The method can be carried out easily and allows reliable and accurate monitoring of the rail using a strain sensor member.

  • Publication number: 20190348560
    Abstract: A back surface contact solar cell has a wafer with an anti-reflection layer on the front surface, with an emitter and a back surface field on the back surface, and with contacts, produced using laser ablation, on the back surface, wherein the pitch is at most 800 micrometers. Furthermore provided is a method for producing such a solar cell.

  • Patent number: 10435437
    Abstract: This invention relates to modified antibiotic peptides, particularly for use in medicine. The invention further relates to composite and methods for destroying microorganisms, such as bacteria, viruses or fungi, and to methods for treating microbial infections. The object of the invention is to develop novel antibiotic peptides, particularly having enhanced antibiotic activity and an expanded spectrum of activity against other strains of bacteria, particularly gram-positive bacteria such as Staphylococcus aureus. According to the invention, the object is attained in a first aspect by a peptide according to claim 1.

  • Publication number: 20160312745
    Abstract: A method for operating an internal combustion piston engine, preferably a spark ignition engine, is disclosed. For each combustion chamber at least one intake valve is closed prematurely or belatedly and an exhaust gas recirculation can be carried out. For each combustion chamber at least two intake valves are provided which are opened at least during the exhaust gas recirculation with different maximum strokes.
