  • Patent number: 10173084
    Abstract: A gas mask is provided with a mask body, which is designed to cover the face of a user, and with an opening in the mask body, which is closed by a speech diaphragm (8) in a gas-tight manner. A funnel (4) is directed toward the speech diaphragm with an opening angle in the range of 20° to 90°. The funnel (4) is arranged in front of the speech diaphragm in the interior space of the mask body in order to focus sound waves onto the speech diaphragm.

  • Patent number: 9195307
    Abstract: An operator control device has an operator control element with haptic feedback. The operator element includes one or more sensors and can be activated by an operator by an inputting element. The operating control device includes first and second ferromagnetic two-dimensional components. The components are arranged in parallel and configured to move relative to each other. The first ferromagnetic two-dimensional component is configured to form the operator control element. The first ferromagnetic two-dimensional component includes at least one flat coil that is arranged on a printed circuit board and is arranged between the ferromagnetic components. The first and second ferromagnetic two-dimensional components are configured to move with respect to each other when said at least one flat coil is energized, and the printed circuit board bearing the flat coil is permanently arranged on a face of said second ferromagnetic two-dimensional component.

  • Patent number: 8957867
    Abstract: A haptic operating device particularly for motor vehicles, having a touch panel having at least one touch-sensitive area. When the area is touched, a switching signal can be triggered and the touch panel can be activated by a motion drive to be able to move at a certain rhythm in the plane of the touch panel. The touch panel is connected to a fixed support by one or more flexible connecting elements. The support and the touch panel form two housing parts of a closed housing, in which at least the display device or the display plane thereof is arranged, and are connected to each other by a sealing device so as to be able to move relative to each other in the plane of the touch panel or in a plane parallel to the touch panel.

  • Patent number: 8584865
    Abstract: The invention relates to a strainer for treating a fibrous material suspension suitable for producing a paper, cardboard, tissue, or other fibrous material web, having a plurality of strainer perforations, the smallest cross-sectional areas of which are approximately of the same size. The sorting effect and the throughput are to be improved such that the cross-sectional areas of the strainer perforations on the inflow side have varying size.

  • Publication number: 20070220942
    Abstract: Method for producing a rotationally symmetrical screening device with a plurality of profile bars and screening basket for a pressurized screen. The method includes inserting profile bars parallel to each other into cut-outs open on an interior circumference edge of bar holders and forming the bar holders into rings, thereby narrowing the cut-outs and clamping the profile bars. The forming of rings includes transferring bending forces to at least two locations on sides of the bar holders not provided with the cut-outs. The method further includes connecting abuttable ends of the bar holders to one another.

  • Patent number: 7263755
    Abstract: A method for fabricating fillings that are utilized in refiners for the purpose of refining paper fiber stock. The filling manufactured in accordance with the method of the present invention includes a base body, an overlay template on the base body and processing elements. The processing elements are inserted into the overlay template that is equipped with corresponding openings. A solid connection is subsequently produced, for example, by way of high temperature welding. Advantages of the method include the selection of optimum materials for the processing elements; the fabrication process is flexible; and the method is especially economical, when measured by the quality of the produced fillings.

  • Publication number: 20070199362
    Abstract: Method for producing a rotationally symmetrical screening device with a plurality of profile bars and screen basket for a pressurizable screen. The method includes producing bent bar holders having a radius of curvature of smaller than a radius of curvature of a finished screening device and having cut-outs open at an edge of an exterior circumference of the bent bar holders. The method also includes inserting profile bars parallel to one another into the cut-outs, and forming rings from the bar holders with inserted profile bars by enlarging the radius of curvature of the bar holders, thereby narrowing the cut-outs and clamping the profile bars. The forming of rings includes transferring bending forces to at least two locations on sides of the bar holders not provided with the cut-outs. The method also includes fixedly connecting respective ends of the bar holders to one another.

  • Patent number: 6943247
    Abstract: Described is a building material composition prepared from or having added thereto a particulate material selected from particulate polysaccharides or particulate polysaccharide derivatives. The particulate material of the building material composition is prepared by a method comprising: (a) forming a feed composition comprising a member selected from the group consisting of polysaccharides and polysaccharide derivatives, and 35 wt. % to 99 wt. % of water, based on the total weight of the feed composition, wherein said member is at least one of swelled and dissolved in the feed composition; (b) contacting, in a mill, the feed composition with a gas stream, thereby converting simultaneously the water of said feed composition into water vapor, and said member of said feed composition into a solid state form of finely particulate material; (c) separating the particulate material from the gas stream; and (d) optionally drying the particulate material.
