Abstract: Hot melt adhesive compositions comprising a block copolymer, a particulate mineral reinforcing agent and glass fiber. The block copolymer is selected from the group consisting of copolyesters, copolyamides, copoly(esteramides) and copoly(ether-esters) melting at a temperature above about 150°C. and having from about30 to about70 weight percent of hard segments and from about 70 to about 30 weight percent of soft segments. The weight ratio of block copolymer to particulate mineral reinforcing agent and glass fiber is in the range of about 3:7 to about 3:2, the weight ratio of block copolymer to glass fiber is at least about 3:4, and the weight ratio of particulate mineral reinforcing agentto glass fiber is in the range of about 1:3 to about 9:1. The compositions are particularly useful for filling voids and cavities in substrates, which comprise applying excess adhesive composition as a hot melt into the cavity, spreading the adhesive composition to fill the cavity, cooling said adhesive composition and thereafter sanding said composition to provide a surface even with the surrounding substrate.

Abstract: The invention relates to an ink supply device for a roller-type inking unit in rotary printing machines with an ink duct roller (26) and a transfer roller (27, 33) which, apart from the ink duct roller, also interacts with one of the inking-unit rollers. The transfer roller (28) is mounted with play over its entire length on its control shaft (5). The circumferential surface of the transfer roller is of continuous design. The roller body of the transfer roller is designed to be flexible perpendicularly to its axis of rotation. Means are provided by which the transfer roller is pressed snugly over its whole length both against the ink duct roller and against the inking-unit roller. These means are omitted if the dead weight of the transfer roller guarantees snug contact of the circumferential surface of the transfer roller with the two adjacent rollers. Very thin ink films can be continuously transferred because, due to its flexibility and its special mounting, the transfer roller adapts completely to the shape of the two circumferential surfaces of both adjacent rollers. <IMAGE>

Abstract: A novel ink printing apparatus utilizes electroosmotic force on a face of dielectric substance substrate 10 between a needle shaped recording electrode 20 and a ring shaped auxiliary electrode 30. When a voltage of a suitable polarity is applied between the electrodes 20 and 30, a fluid ink (of solvent ink) 40 laid on the dielectric substrate 10 to range from the electrodes 30 to 20 travels by the electroosmotic force and makes protrusion 41 on the end tip 20' of the recording electrode 20. By applying a high voltage between a counter electrode 60 behind a recording paper 50 and the recording electrode 20, the fluid ink 41 flies to the recording paper.

Abstract: Analysegerät zur Bestimmung des Kupfergehaltes im Abwasser, insbesondere von Galvanikanlagen, wobei dem Abwasser in Intervallen Proben entnommen und diese Proben in einem Gefäß gesammelt werden, dann durch Zugabe eines Reduktionsmittels das Cu(II) zu Cu(I) reduziert wird und anschließend nach Einstellung eines bestimmten pH-Wertes mit Hilfe einer Pufferlösung ein Reagenz für eine Farbbildung beigegeben wird und schließlich aus dieser Probe der Kupfergehalt durch Kolorimetrie bestimmt wird. Damit auch die Kupfer-Cyankomplexe erfaßt werden können, wird die Abwasserprobe mit einer metallhaltigen Säure in einem eigenen Gefäß aufbereitet, wobei ein Metall verwendet wird, das wie Kupfer einen Cyan-Komplex bildet, der jedoch stärker als der Kupfer-Cyankomplex ist. Zur Bestimmung des Blindwertes wird die aufbereitete Abwasserprobe vor und nach Zugabe des Einfärbemittels kolorimetriert.

Abstract: Die Einrichtung zur Erzeugung einer Schaltanweisung weist drei drehzahlabhängige Schwellwertschalter (6, 7, 12) auf. Der erste Schwellwertschalter (6) ist über ein Und-Gatter (5) mit einem Hochschaltsignalgeber (9) verknüpft. Dieses Und-Gatter schaltet nur durch, wenn das Gaspedal (1) weniger als 20% durchgetreten und die Drehzahlschwelle des ersten Schwellwertgebers (6) erreicht ist. Wird das Gaspedal (1) stärker durchgetreten, so leuchtet der Hochschaltsignalgeber (9) erst auf, wenn die Drehzahlschwelle des dritten Schwellwertschalters, nämlich die maximal zulässige Drehzahl, erreicht ist. Der Herunterschaltsignalgeber (11) leuchtet auf, wenn die Motordrehzahl unter der Schwelle des zweiten Schwellwertschalters (7) sinkt. Durch diese Gestaltung werden Schaltanweisungen gegeben, die die Motorleistung des Fahrzeugs hinreichend berücksichtigen, ohne daß diese Motorleistung gemessen werden muß.
