    摘要： A process for the preparation of dialkylamines of the general formula I, ##STR1## in which R.sup.1, R.sup.2, and R.sup.3 denote C.sub.1 -C.sub.12 alkyl, by the reaction of a dialkylamine of the general formula II ##STR2## in which R.sup.1 and R.sup.2 denote C.sub.1 -C.sub.12 alkyl, with alcohols R.sup.3 --OH in the presence of a (copper chromite/alkaline-earth metal chromite)-containing hydrogenation/dehydrogenation catalyst, in which the reaction is carried out in the liquid phase over a fixed bed catalyst in the presence of the water formed during the reaction at temperatures ranging from 180.degree. to 210.degree. C. and pressures ranging from 40 to 120 bar.

    摘要： Avivage deposits on and between the dents of a reed, especially in an air weaving loom, are removed by heating at least a portion of the reed dents in the vicinity of the weft insertion channel to a temperature sufficient to melt the avivage which can then be discharged from the reed dents and the spaces between the reed dents by dripping downwardly, for example, into a collecting trough.

    摘要： When a faulty weft thread must be removed after it has been bound into the fabric and beat-up, it is necessary to perform a so-called reverse weaving operation following the stopping of the normal weaving operation in response to a stop signal signifying that a faulty weft thread has been detected. For this purpose the loom main shaft and the heald drive shaft are rotated for a number of rotational degrees in the same direction in which these shafts are rotated just prior to the stopping of a weaving operation in response to the above mentioned signal. Next, the drive between the main shaft and the heald shaft is interrupted. Next, the main shaft and thus also the reed shaft and with it the reed, are rotated back within a predetermined angular range between two successive reed beat-up motions. During this time the heald shaft is rotated back, preferably to the so-called detection point with a higher r.p.m., or rather with a higher angular speed than the main shaft. This function is accomplished by an auxiliary step-up transmission gear between the main shaft and the heald shaft. The auxiliary gear is bypassed during normal operation when there is no weft fault and it is connected in series during the operation for removing of a faulty weft thread.
