  • 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.

  • Patent number: 6958429
    Abstract: The invention relates to absorbent polymers based on optionally partially neutralised, monoethylenically unsaturated, acid group-carrying monomers. The surfaces of said polymers are re-cross-linked. The inventive polymers also have cyclodextrines and/or cyclodextrine derivatives which are covalently and/or ionically bonded and/or included therein.

  • Patent number: 4693713
    Abstract: The invention concerns an absorbent for blood and serous body fluids consisting of at least two components, A and B, whereby component A is a crosslinked synthetic or natural polymer or copolymer, and component B is an organic and/or inorganic compound which is water-soluble and solid at normal temperature. The absorbent contains 25 to 98 weight % of component A and 2 to 75 weight % of component B. The invention, moveover, concerns the use of the said absorbent for absorption and/or retention of blood and serous body fluids, in particular in absorbent throwaway articles for surgical, medical and hygienic purposes.

  • Patent number: 4415295
    Abstract: A mineral mining installation serves to win mineral by explosive blasting. The installation employs a shuttle conveyor arranged alongside a mineral face. Roof supports stand side-by-side at the side of the conveyor remote from the conveyor. The roof supports are connected to the conveyor through shifting rams and have roof-engageable caps or the like supported on hydraulic props. The pans of the conveyor have upstanding walls at the rear side nearest the roof supports which carry rails at their upper ends. The roof caps have wall components pivoted thereto and hydraulic piston and cylinder units serve to swing the wall components up and down. When explosive blasting takes place the wall components are swung down to engage on the walls of the conveyor pans to form a screen between the winning region and the access region of the working.
