Abstract: Un appareil, servant à produire des épreuves couleurs par voie électrophotographique, comprend un poste de chargement, un poste d'exposition et un poste de développement. Procédant au départ à des séparations par demi-teintes chromatiques de l'original à reproduire, ledit appareil, qui utilise une méthode originale, commande électroniquement l'exposition et les potentiels au niveau des postes de chargement et de développement, afin de produire une épreuve. Ledit appareil est conçu pour produire des épreuves qui correspondent au gain ou à la perte de points et à la densité des feuilles d'impression imprimées par une grande variété de presses commerciales, procédant pour commencer aux mêmes séparations que celles utilisées pour produire les épreuves. Lesdites séparations sont ensuite modifiées jusqu'à ce que l'appareil produise une autre épreuve qui est une reproduction acceptable de l'original à reproduire. Les séparations modifiées sont ensuite utilisées pour produire sur la presse commerciale une feuille d'impression qui sera une reproduction acceptable de l'original à reproduire.

Abstract: Le circuit d'une section de sélectivité numérique d'une fréquence intermédiaire zéro agit sur un signal d'entrée récupéré (12), synchronisé numériquement par une première horloge (22) à une vitesse de synchronisation de fréquence dans un récepteur. Le circuit utilise une seconde horloge (24) fonctionnant à une vitesse inférieure à celle de la première horloge (22) pour synchroniser des moyens de filtration numérique FIR d'ordre N (16) pour limiter sélectivement le spectre de fréquence du signal d'entrée récupéré (12). Un second moyen de filtration numérique (20, 28) est couplé à la sortie des premiers moyens de filtration numérique FIR (16). Le second moyen de filtration numérique (20, 28) fonctionne à une vitesse d'horloge inférieure ou égale à celle de la seconde horloge. Les seconds moyens de filtration numérique (20, 28) sont utilisés pour limiter sélectivement le spectre de fréquence du signal d'entrée récupéré (12).

Abstract: The invention relates to a process and a device for producing mineral-fibre boards (3), in which, following a thickness precompression in a prepress (4), a longitudinal compression is performed by bulging out of the mineral fibre layer (3) in several successively arranged compression stages (8 to 11) up to entry into the tunnel oven (5). This achieves the effect of a gradual longitudinal compression, which results in a very uniform and lasting alignment of the fibres within the layer (3). This in turn increases to a considerable extent the compressive strength and abrasion resistance of the end product. <IMAGE>
