  • Patent number: 8259971
    Abstract: A Hearing apparatuses is provided. The hearing apparatus includes a programming socket that features at least a first connection and a second connection, with a signal processing system that is connected to the second connection, and with a control system. The control system taps the potential of the first connection. The control system furthermore engages the signal processing system in a first function when the first connection reaches the predetermined potential and in a second function when the potential of the first connection deviates from the predetermined potential. This enables multiple usages for example of the input of a programming interface of a signal processing IC.

  • Publication number: 20100124861
    Abstract: The invention relates to a method for the production of cellulose shaped bodies according to the dry-wet extrusion method (Lyocell method) with high degree of whiteness and bioactive action for use in the textile sector and paper production. In the context of the invention, the term “bioactive” refers to antimicrobial efficacy, based on the antibacterial action of the element silver, which is used as nanoscale reagent for increasing the efficacy thereof. The chemically inert and, at the same time, bactericidal effect is used in the production of sports and leisure clothing with a high degree of whiteness and papers with a long shelf life. Use is possible in the medical sector, for example, for wound dressings, textiles for hospitals, and in the filter and packaging industry.

  • Publication number: 20060283567
    Abstract: The invention relates to a method for producing cellulosed molded articles having a functional effect. The method is characterized by charging cellulosed fibers or films with incorporated ion exchangers having bactericidal metal ions and/or ionic pharmaceutical active substances in such a manner that a depot of these active substances is built up in the fiber. Said depot time releases the active substances in the amount of the corresponding equivalent concentration when the fibers and films are used in aqueous solutions. The invention also relates to molded articles produced according to the inventive method.

  • Patent number: 7052775
    Abstract: A process for producing cellulosic formed materials having high water retention capacity according to the dry-wet extrusion process by producing a solution of 5 to 20 wt.-% of cellulose in a hydrous tertiary amine oxide, extruding the solution, stretching the extrudate in a non-precipitating medium, and precipitating the formed materials in an aqueous or alcoholic precipitating bath, characterized by extruding a solution including 0.01 to 250 wt.-%, relative to cellulose, of at least one superabsorbent polymer having a grain size of ?100 ?m. The fibers, films, and composite materials being formed are remarkable for their high water retention capacity and are suitable in the production of hygiene products, baby or disposable diapers, sanitary towels, tampons, incontinence articles, absorbent patches, wound dressings, strappings, bandages, absorbent cloths, moisture-absorbing clothing, bed mattings, filter materials or filters, packaging materials, or cable sheathings.
