Abstract: Die Erfindung betrifft eine Abtastvorrichtung für von Gleichstrommotoren angetriebenen Taktscheiben mit lichtdurchlässigen Schlitzen zur Abgabe von Signalen an eine Auswerteschaltung in Schreib- oder Büromaschinen ähnlicher Bauart, wobei die Schlitze (4) durch eine als Stellungsfühler ausgebildete Doppellichtschrankenanordnung (5) mit einer Lichtquelle (6) und zwei Lichtempfängern (7, 8) abtastbar sind. Um eine exakte Steuerung des Gleichstrommotors (1) und der damit verbundenen Abtriebsteile, z. B. einer Typenscheibe oder eines Druckwerksschlittens zu gewährleisten, ist es erforderlich, daß die Signale an den beiden Ausgangskanälen, die um ein Viertel der Taktperiode versetzt sind, einen bestimmten Maximalwert nicht unter- bzw. überschreiten. Für diesen notwendigen Abgleichvorgang sind bereits elektrische Steuervorrichtungen bekannt, die aber für billige Büromaschinen weniger geeignet sind. Das Abgleichen der beiden sinusförmig ausgebildeten Signale an den Ausgangskanälen der Lichtempfänger (7, 8) wird erfindungsgemäß dadurch erzielt, daß der Querschnitt des Lichtstrahlenbündels der von der Lichtquelle (6) kommenden Lichtstrahlen durch in deren Strahlengang von Hand einschwenkund justierbare Blenden (21, 22) auf einfachste Weise veränderbar ist. Hierdurch ist eine schnelle Abgleichung der Maximalwerte der Ausgangsspannungen in den Lichtempfängern (7, 8) auf eine vorgegebene Spannung möglich.

Abstract: A procedure for smoothing off the edges of springs is characterised in that the springs are heated by a laser beam until the desired smoothing off of the edges takes place as a result of softening or fusing of the surface, whereupon the heating operation is stopped. The procedure can be used in an advantageous manner for smoothing off the edges of burr which has developed in the manufacture of micro sliding contacts by punching. The laser beam is preferably defocused, that is, it is focused on a point in front of or behind the surface to be exposed to the laser beam, which results in "soft" radiation. An especially high surface quality can be achieved due to the avoidance of mechanical rework and due to the contactless working. This procedure is especially cost-effective, since it is also easy to automate.
