  • Patent number: 10464124
    Abstract: A method and a system for configuring a strand guiding system (8, 8a, 8b) of a continuous casting machine (2) and such a strand guiding system (8, 8a, 8b). A strand guiding segment (10g-r) guides a metal strand in the strand guiding system (8, 8a, 8b). The strand guiding system (8, 8a, 8b) has a plurality of strand guiding segments (10g-r) and respective control units (22g-r), wherein each control unit (22g-r) identifies its strand guiding segment (10g-r), and each control unit (22g-r) automatically depends on the strand guiding segments (10g-r) identified by the control unit (22g-r). The strand guiding system (8, 8a, 8b) and the strand guiding segment (10g-r) are prepared for the performance of the method herein disclosed.

  • Patent number: 4533590
    Abstract: A carrier web coated with amino resin wherein at least one surface is resinated is produced by applying a spreadable amino resin dispersion containing 70-90% by weight of amino resin and 30-10% by weight of a liquid dispersant to at least one surface of an uncoated carrier web in an apparatus comprising:(a) unwinding station for unwinding uncoated carrier webs from rotatable supply rolls,(b) means for conveying the uncoated webs comprising a plurality of cooperating pressure rolls rotatably mounted in parallel relationship,(c) a coating means for applying a brushable amino resin dispersion to the web, and(d) a belt press for compression-molding and curing the coated web.

  • Patent number: 4408327
    Abstract: A method for synchronizing switching mechanisms or program sequences to an external frame clock pulse, wherein after a given period of time the switching mechanism or program is enabled to be reset and that after this enabling the resetting takes place with the edge of an external clock pulse. Moreover, the resetting takes place immediately after enabling if the edge of the external clock pulse has appeared earlier in time and the resetting takes place in any case no later than after a further given period of time even if the edge of the external clock pulse has not arrived. An apparatus for carrying out the method is also disclosed.

  • Patent number: 4251157
    Abstract: A strip of negatives is transported over a slit extending transverse to transport, and the image of successive slit-like elements of each original is projected onto the row of photosensitive zones of a CCD image sensor unit. A photodetector also receives the image of each slit-like element, either simultaneously with the CCD image sensor unit or earlier at a more upstream location, and generates an output signal indicating the average transparency of the whole slit-like image element. The average-transparency signal is used to control the clocking frequency of the clock signal which drives the CCD image sensor unit, either by changing the clocking frequency for each read-out of the image sensor unit or by changing the clocking frequency once per original, in the latter case a peak detector circuit being used to ascertain the transparency of the maximum transparency slit-like element of each original.
