摘要:
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.

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.
摘要:
The present invention relates to the continuous preparation of alcohol- and plasticizer-free finished nitrocellulose solutions having a particularly low water content by partial distillative falling-film evaporation of comparatively water-rich, optionally emulsion-like crude nitrocellulose solutions which are preferably provided by dissolving nitrocelluloses of the customary solid forms offered, which are known to be initially water-moist as a result of the preparation, in preferably ethyl acetate.

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.

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. Examples of building material compositions according to the present invention include tile adhesives and joint fillers.

Manufactured by the method are screens provided with screening holes (7). For that purpose, a screen is composed of a plurality of screen strips (2) which, together with profile bars (1), are aligned parallel to one another and positively joined to one another and to at least two transverse beams (3). Screens manufactured in this manner are used in the paper industry as screen baskets.
摘要:
This invention concerns a process for making rotationally symmetric screen baskets featuring axially parallel bars with screen slots contained in between and, for support of the bars, rings that are coaxial with the basket axis, the rings being provided with recesses that are open toward the rim and the bar feet being placed and fastened in the recesses.The invention is characterized by the following features:(a) the bars are placed in the recesses while the rings do not have their final rounded shape yet;(b) next, the rings are rounded so as to close the circular shape and to clamp the bars in place in the recesses that are being constricted by the rounding.
