  • Publication number: 20200411747
    Abstract: A ferroelectric material includes a mixed crystal having AlN and at least one nitride of a transition metal. The proportion of the nitride of the transition metal is selected such that a direction of an initial or spontaneous polarity of the ferroelectric material is switchable by applying a switchover voltage. The switchover voltage is below a breakdown voltage of the ferroelectric material.

  • Publication number: 20200407263
    Abstract: A method for the production of glass or glass ceramic elements from flat glass or glass ceramic parts is provided where the edges of the glass or glass ceramic elements are treated by a combination of two processes. The flat glass or glass ceramic element with an edge surface connecting the two side surfaces is produced. The edge surface has at least one first elongated, strip-shaped edge region and at least one second elongated strip-shaped edge region, which are formed by a ground edge. The edge regions extend in the longitudinal direction along the edge surface and along the side surfaces. The first edge region has elongated parallel filamentary damages that are parallel and adjacent to one another and, in particular, spaced apart equidistantly, in the longitudinal direction thereof extending transversely to the side surfaces and along the surface of the first edge region.

  • Publication number: 20200369551
    Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.

  • Publication number: 20200355107
    Abstract: A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine (200) with the following steps: set up (111, 116) a pressure difference model, which models a measured pressure difference (?p) which drops across the particulate filter (210) as a function (220) of a volume flow ({dot over (V)}) through the particulate filter (210) with an offset value (a0, C); measure (120) multiple measurement values (245) for the pressure difference (?p) at different volume flows ({dot over (V)}) and solve (130) the pressure difference model as a function of the pressure difference (?p), whereby the offset value (a0, C) is also determined.

  • Publication number: 20200290152
    Abstract: A method provides for producing modifications in or on a transparent workpiece using a laser processing device. The laser processing device has a short pulse or ultrashort pulse laser that emits laser radiation having a wavelength in the transparency range of the workpiece and which has a beam-shaping optical unit for beam shaping for focusing the laser radiation. The transparent workpiece is composed of a material that has a plurality of phases, of which at least two phases have different dielectric constants, of which in turn the one phase is a phase embedded in the form of particles, which phase is substantially surrounded by the other phase, and wherein the product of the volume of the particles specified in cubic nanometers and the ratio of the absolute value of the difference of the two different dielectric constants to the dielectric constant of the surrounding phase is greater than 500.

  • Patent number: 10737967
    Abstract: A method is provided for separating a portion from a sheet-like glass or glass ceramic element along an intended separation line to divide the element into the portion and a main part. The method includes producing filamentary damages a volume of the glass or glass ceramic element adjacently aligned along the separation line, the filamentary damages are produced by laser pulses of a laser, the glass or glass ceramic element comprises a material that is transparent for the laser pulses; displacing incidence points of the laser pulses on a surface of the glass or glass ceramic element thereof along the separation line; and subjecting the material of the glass or glass ceramic element located in a region of the portion to a phase transition so that the material contracts to detach the portion from the main part at the adjacently aligned filamentary damages along the separation line, while the main part remains intact as a whole.

  • Patent number: 10702812
    Abstract: A filter device has a cup-shaped filter housing and a filter element disposed in the filter housing. A filter head is connectable to the filter housing and forms a cover for the filter housing. A spring element is provided that is acting on the filter element. The filter head has at least one first form-fit element. The filter housing has at least one second form-fit element for interacting with the at least one first form-fit element. The spring element is arranged such that the filter head and the filter housing for reaching a closed position, in which the at least one first form-fit element and the at least one second form-fit element engage each other, are movable relative to each other axially against the force of the spring element.

  • Publication number: 20200199007
    Abstract: A method is provided that includes producing filamentary damages in a volume of a glass or glass ceramic element adjacently aligned along a separation line and extend obliquely relative to a surface of the glass or glass ceramic element; and separating a portion from the glass or glass ceramic element along the separation line. The step of producing the filamentary damages includes directing laser pulses of an ultrashort pulse laser obliquely on the surface so that the laser pulses have a light propagation direction that extends obliquely relative to the surface and so that the filamentary damages resulting from the laser pulses have the longitudinal extension that extends obliquely relative to the surface; generating a plasma within the volume with the laser pulses; and displacing the laser pulses at points of incidence over the surface along the separation line.
