    摘要： The present invention relates to a membrane being suitable for, for example, hemodialysis. Said membrane comprises at least one hydrophobic polymer and at least one hydrophilic polymer. According to the present invention the outer surface of the hollow fiber has pores in the range of 0.5-3 μm and the numbers of said pores in the outer surface are in the range of 10,000 to 150,000 pores per mm2, preferably in the range of 18,000 to 100,000 pores per mm2, and most preferably in the range of 20,000 to 100,000 pores per mm2. The present invention further relates to a process for the preparation of said membrane and use of said membrane in hemodialysis, hemodiafiltration and hemofiltration, and in dialysis and filtration in general, for example in water purification or dehydration.

    摘要： Cylinder head gasket with a gasket plate having several sheet-metal layers and at least one combustion chamber aperture, wherein a first outer sheet-metal layer is provided with an annular bead which surrounds the combustion chamber aperture, projects in the direction towards an adjacent, second sheet-metal layer and abuts against the latter, and wherein to limit the deformation of the bead a metal spacer ring is attached by welding to one of the two layers radially adjacent to the bead, the spacer ring facing the other layer and surrounding the combustion chamber aperture; in order to make a simple optical examination of the quality of the welding join possible, the spacer ring is attached in a gas-tight manner to the layer supporting it by a continuous, annular laser welding seam closed upon itself and uniform except for an area of overlap, wherein the seam is doubled in the area of overlap.

    摘要： A process for the production of hydrophilic membranes using at least one hydrophobic polymer and polyvinyl pyrrolidone as a hydrophilic polymer, membrane-forming shaping of the polymers and immobilization of the polyvinyl pyrrolidone is characterized in that the polyvinyl pyrrolidone is immobilized on and/or in the membrane by treatment with an aqueous solution of peroxodisulphate in a hot condition. The solution of peroxodisulphate is kept substantially free of oxygen during immobilization by degassing the solution. The membranes are used for hemodialysis, hemodiafiltration and hemofiltration of blood.
