摘要： A web drying apparatus, e.g., for a paper web, includes several heatable drying cylinders arranged in at least one row with at least one respective endless loop drying wire and preferably arranged in two rows of cylinders with two respective wires. A wire guide roll is between and offset from two of the adjacent cylinders in the one row. The one endless loop dryer wire carries the web thereon on a first part of the web loop path from the first cylinder to the wire guide roll. There the web separates from the wire and travels to a second cylinder in the second row. The wire wraps around the wire guide roll and returns on a second part of the web loop path to the next cylinder in the first row, without supporting a web. On the path between the first and third cylinders and around the wire guide roll, the wire defines a loop. An air guide box and a blower are arranged within the loop. The air guide box produces a vacuum at the first part of the wire loop path for drawing the web against the wire. An air channel extends between the air guide box and the blower. At least one drive nozzle outlets into the air channel. The air channel draws air out of the first part of the loop path to create the vacuum there. The blower directs a stream of air through the wire, at the second part of the wire loop path, and then to a pocket outside the second loop part. The drive nozzle and the blower are supplied by independently controlled flows of blown air.

摘要翻译： 卷筒纸干燥装置，例如用于纸幅，包括布置在至少一排中的几个可加热干燥筒，其具有至少一个相应的无端环形干燥线，并且优选地布置在具有两根相应导线的两排圆筒中。 线引导辊位于一排中的两个相邻气缸之间并偏移。 一个无端环形干燥器丝线在从第一圆柱体到导丝辊的卷材环路径的第一部分上承载着卷材。 在那里，网与线分离并行进到第二排中的第二圆柱体。 电线缠绕在导丝辊周围，并且在卷材环路径的第二部分上返回到第一排中的下一个圆柱体，而不支撑卷材。 在第一和第三圆柱体之间以及绕线导向辊周围的路径上，线限定回路。 引导箱和鼓风机布置在回路内。 引导箱在线环路径的第一部分处产生真空，用于将幅材拉到线材上。 空气通道在导风箱和鼓风机之间延伸。 至少一个驱动喷嘴出口进入空气通道。 空气通道将空气从循环路径的第一部分中抽出，以在那里产生真空。 鼓风机引导空气流穿过导线，在导线环路径的第二部分处，然后引导到第二环部分外部的口袋。 驱动喷嘴和鼓风机由独立控制的吹风空气供给。

摘要： A spacing element for spacing a pipe from a protective pipe outwardly surrounding the latter, has an annular body including a plurality of segments adapted to be placed on an outer surface of the pipe and each having a plurality of projections provided with sliding surfaces and adapted to abut against the protective pipe. The spacing element further includes a plurality of electrically insulating wedge-shaped connecting portions for connecting the segments with one another. The connecting portions may be formed as trough-shaped members embracing trough-shaped flanges of the segments. The connecting portions may also be formed as wedge members insertable into bores of a projection of one of the segments engaging a recess of an adjacent segment, or fixable to an outer surface of such projection. Additional connecting members such as electrically insulating pins, straps and strings may be provided for connecting the segments with one another.

摘要翻译： 用于将管道与保护管隔开的间隔元件用于将管道与围绕后者的保护管隔开，具有环形体，其包括适于放置在管的外表面上的多个段，每个段具有设置有滑动表面的多个突起， 抵靠保护管。 间隔元件还包括用于将片段彼此连接的多个电绝缘的楔形连接部分。 连接部分可以形成为包围节段的槽形凸缘的槽形构件。 连接部分也可以形成为可插入其中一个部分的突出物的孔中的楔形构件，其接合相邻段的凹部，或可固定到该突起的外表面。 可以提供诸如电绝缘销，带和串的附加连接构件用于将段彼此连接。
