Abstract: An open ended, flat spiral belt (10) is joined at its ends on a roll (12) to form an endless cover. A spiral belt is fitted with a zipper assist (24) in the seam area to facilitate the joining of the spiral belt on the roll. One part (26) of the zipper assist (24) is removably attached to one end (40) of the spiral belt with the other part (28) of the zipper assist being removably attached to the other end (42) of the spiral belt. When the two sections (26, 28) of the zipper assist (24) are zipped together, they pull the two ends (40, 42) of the spiral belt (10) together, allowing for interdigitation of the spiral loops of the spiral belt, which then forms a channel for the introduction of a seam wire (60). Once the spiral belt (10) is seamed on the roll, the zipper assist (24) is removed and the roll (12) is set in slow motion at about ten revolutions per minute. The entire fabric is subjected to application of heat from a hot air gun to set the spiral belt, now in the form of a spiral shrink sleeve.

Abstract: Système informatique et procédé permettant de reproduire un livre sur les images-écrans d'un terminal à écran de visualisation. Une représentation de livre est formée de plusieurs entités disposées en série qui se recouvrent successivement. On peut visualiser des données relatives uniquement à des entités ou à des parties d'entités ne se chevauchant pas. Un système de processeur change l'affichage de la série de sorte que les entités recherchées soient affichées sans chevauchement dans une position respective de la série. Chaque entité succédant à l'entité recherchée dans la série recouvre respectivement l'entité qui lui succède, s'il y en a une, et chaque entité précédant l'entité recherchée dans la série recouvre respectivement l'entité qui la précède, s'il y en a une, pour afficher sur l'écran l'entité recherchée qui n'est pas recouverte de la série. La position des images-écrans des données visualisables de la série varie ainsi en fonction de l'entité fournissant les données et correspondant à la position de l'entité dans la série. Un traitement par processeur règle la position des tabulations définissables par l'utilisateur couplées aux entités pour maximiser la visualisation des tabulations. Des numéros de pages et d'autres repères sont utilisés pour fournir des indications relatives aux positions des entités dans la série. Dans un autre mode d'exécution, les entités se trouvant le plus près d'une entité non recouverte sont moins recouvertes par des entités voisines que les entités se trouvant le plus loin d'une entité non recouverte qui sont recouvertes par les entités respectivement voisines.

Abstract: A method of removing and placing sediments, sludge or other materials from/on the bed of a stretch of water, in which a hood-like receiving device is lowered onto the bed of the stretch of water and during the removal is pressed at least partly into the bed while material to be removed is enclosed, whereupon the water is displaced out of the receiving device and the enclosed material is removed from the bed of the stretch of water, is to bring about in particular better separation of the material to be removed, from the free water and is to be less complicated. To this end, the receiving device is closed at the bottom after being pressed into the bed and, to remove the enclosed material, is raised with the latter. On the other hand, during the placing of materials, the receiving device is brought through the water together with the enclosed material onto the bed of the stretch of water. After the bottom closure plate (11) is opened, the material can be pressed out of the receiving device by means of the pressure plate (6) and be deposited compactly on the bottom. <IMAGE>

Abstract: In the interest of ease of manufacture, hybrid lasers of distributed-Bragg-reflector type are preferred for use as light sources in optical communications. We have found that such lasers are prone to mode instabilities which can adversely affect the error rate. However, by making the reflectance peak of the Bragg reflector sufficiently wide that it is capable of supporting two or more modes of optical radiation it is possible to render mode instability of negligible influence on error rate, provided that mode dispersion is not a problem.

Abstract: The invention relates to a circuit arrangement for operating a low-pressure mercury discharge lamp by means of a high-frequency current which consists of a DC component G and a high-frequency AC component W, comprising
     switching means I for generating the high-frequency AC component W from a supply voltage,   asymmetry means II for rendering an amplitude A1 of the high-frequency AC component W in a first polarization direction and an amplitude A2 of the high-frequency AC component W in a second polarization direction unequal to one another, and   DC means III for generating the DC component G.   
     According to the invention, the polarity of the DC component G coincides with the polarization direction of the greater of the two amplitudes A1 and A2. It is achieved by this that striations in a low-pressure mercury discharge lamp operated on the circuit arrangement can be rendered invisible over a wide range of powers consumed by the lamp.
