    摘要: A process for the manufacture of secondary amines, especially fatty amines, from alcohols and ammonia over a hydrogenating catalyst in the presence of hydrogen, in which the reaction mixture essentially consists of alcohol and the amine formed, with only little ammonia, the latter being added progressively and the water formed in the reaction being removed progressively.

    摘要: A weaving machine for producing a woven fabric has a shedding device to form a loom shed of warp material, a weft insertion device for inserting a preferably tape-shaped or band-shaped weft material into the loom shed, a drawing-off device for drawing off the finished fabric in a drawing-off direction, fabric movement device for moving the fabric back and forth in the warp direction to bring the last inserted weft material into contact with the binding point or fabric edge. A shed limiter device limits the opening of the loom shed from above and below the warp, and is movable back and forth in the warp direction. The shed limiter device only loosely bounds the fabric and essentially without actively clamping or pinching or contacting the fabric and/or the last inserted weft material, at least while moving in the direction opposite the drawing-off direction.

    摘要: For weaving pattern formation of a woven fabric with weft threads (3), warp threads (1) and effect threads (2), data sets (20) are produced according to a method in which data values are derived from weft sequence numbers (30) and from positions of interlacing points (P) of an effect thread (2) with the weft threads (3) in the pattern repeat (29). These data sets (20) are supplemented by further data values (31, 32, 33, 34) derived from the weaving pattern, in such a manner so that they form a pattern draft (28) for a weaving pattern with additional weft effects. In a weaving machine with devices for slidingly displacing effect threads (2) in the weft direction (12), the weaving pattern formation is derived from the data sets (20) of this pattern draft (28).

    摘要: A door arrangement includes a first part, in particular a door leaf, a second part, in particular a door frame, on which the first part is pivotably articulated about a pivot axis, a closing hinge, which connects the first part and the second part, for a closing movement of the first part relative to the second part and a damping hinge connecting the first part and the second part, to damp the closing movement. The door arrangement can be displaced between a closed position, in particular in which the first part rests in a closing manner on the second part, and an opened position, in which the first part is pivoted at a pivoting angle that differs from zero about the pivot axis in relation to the second part.

    摘要: Polyoxyalkylene glycols are prepared by a process in which tetrahydrofuran is polymerized with a total of not more than 95 mol %, based on the amount of tetrahydrofuran used, of one or more comonomers from the group consisting of the cyclic ethers and acetals in the absence of water and in the presence of a monohydric alcohol or of a monocarboxylic acid with the aid of an anhydrous heteropoly acid catalyst, and the polyoxyalkylene glycol is liberated from the resulting polyoxyalkylene glycol monoethers or polyoxyalkylene glycol monoesters by cleavage of the monoether or monoester bond.
