摘要： An endless conveyer or drive belt reaches with a portion of its cross-sectional configuration facing toward respective guide or drive rollers, into corresponding ring grooves in the rollers. The projecting portion includes an endless helical spring partially embedded in the drive belt. The ends of the helical spring are connected to each other. The spring keeps the belt trained on the rollers.

摘要： A mounting ring of synthetic material for fitting two pipe sections in place relative to each other, has a radial flange (1) and an axial neck (2). Tongues (3, 4, 5, 6) of differing lengths extend radially inwardly and radially outwardly from the neck. These tongues are preferably formed as part of the ring, for example, when molding the ring of synthetic material. The longer radially outer tongues bend over, snap into a groove, and center the ring in a pipe socket. The shorter radially outer tongues support the ring in the socket. When a pipe end is inserted into the socket through the ring the longer radially inner tongues bend and center the pipe in the socket while the shorter radially inner tongues support the pipe end. Thus, the inner surfaces of the pipe sections remain in alignment with each other because the shorter tongues act like spokes against forces acting crosswise on the pipe sections relative to their length.
摘要翻译：用于将两个管段相对于彼此配合在一起的合成材料的安装环具有径向凸缘（1）和轴向颈部（2）。不同长度的舌（3,4,5,6）从颈部径向向内和径向向外延伸。这些舌片优选地形成为环的一部分，例如，当模制合成材料的环时。较长的径向外部舌片弯曲，卡入凹槽，并将环中心放置在管道插座中。较短的径向外舌支撑在插座中的环。当管端通过环插入到插座中时，较长的径向内部舌片将管道弯曲并居中，并且较短的径向内部舌片支撑管端。因此，管段的内表面保持彼此对准，因为较短的舌片相对于它们的长度而相反地作用在管段上作用的力。

摘要： A transport roller, especially for transporting sheet material such as sheets of paper, has a rigid core surrounded by a friction increasing jacket of elastic material. At least one member is inserted between the jacket and the roller for preventing a relative axial displacement between the core and the jacket. Such member is an endless helical spring partially embedded in the jacket and projecting into a ring groove in the core, whereby the jacket is firmly held in place on the core against any relative axial displacement.
摘要翻译：特别是用于输送诸如纸张的片材的输送辊具有由弹性材料的增加摩擦的夹套围绕的刚性芯。在护套和辊之间插入至少一个构件以防止芯和护套之间的相对轴向位移。这种构件是部分地嵌入护套中并且突出到芯中的环形槽中的环形螺旋弹簧，由此护套牢固地保持在芯上的任何相对轴向位移。
