Abstract: A device (101) for rectifying warp-yarn breaks in a loom is first positioned approximately at the broken warp yarn (11) by being guided to the catch lamella (21) which belongs to the broken warp yarn (11). After the removal of the broken warp yarn (11), a new auxiliary warp yarn (1) is introduced into the catch lamella (21) and the heald (31), in that two laterally slotted draw-in tubes (71,72) alternately blow the auxiliary warp yarn (1) through orifices in the catch lamella (21) and in the heald (31). The auxiliary warp yarn thereby passes out of the blowing orifice of one draw-in tube (71) into a suction orifice of the other draw-in tube (72). In this operation, the draw-in tubes (71,72) are moved further in steps in the warp direction of the loom, until they reach a perforated needle (6c) which is inserted through the weaving reed (4) and into which the auxiliary warp yarn (1) is finally threaded. A warp-yarn break can be rectified definitively by means of this device (101) without additional work.

Abstract: L'invention concerne un procédé de traitement et de préparation d'un échantillon (7) d'une ou de plusieurs molécules non volatiles ou thermiquement instables pour une analyse spectrale de masse qui consiste à utiliser une solution de ces molécules dissoutes dans un solvant, à congeler la solution de molécules dissoutes pour former une solution congelée (8) et à exposer la solution congelée à une source d'énergie (30) pour effectuer la désorption des molécules à analyser de la surface de la solution congelée. Les molécules désorbées peuvent être ionisées directement lors de la désorption ou peuvent être photo-ionisées après désorption (40), si nécessaire, puis analysées de manière classique dans un spectromètre (60) de masse. Le procédé atténue ou minimise la fragmentation ou l'agglomération possible de telles grandes molécules pendant la désorption à partir de l'échantillon congelé et assurent également une désorption plus fiable et uniforme. Si on le désire, les molécules désorbées peuvent être soumises à une fragmentation séparée et régulée avant de les introduire dans la zone finale d'analyse spectrale de masse. Le procédé peut être associé à un équipement de chromatographie liquide.

Abstract: The invention relates to a process for producing printed circuit boards with solder pads which are to be provided with a solder deposit and which are initially surrounded by a boundary layer of defined thickness which prevents soldering; the printed circuit board is then introduced into a solder bath in which the regions to be soldered are covered with a sealing element; when the printed circuit board is removed from the bath, the covering achieves a separation of the enclosed volumes of solder from the liquid solder in the dipping bath or in the soldering chamber, appropriate volumes of solder being defined in the cavities above the solder pads. Compared with the prior art, this has the advantage that the covering can be carried out by simple means and the process of forming the solder pads can be carried out separately from the actual dip soldering operation. <IMAGE>
