Abstract: The tires for vehicles possess under their tread a belt which extends in the circumferential direction. At least one, preferentially two, layers contain, as strengthening and stabilizing means, foils or sheets with direction-dependent rigidity, which possesses its highest value in a preferred direction. The foils or sheets are so arranged that the preferred direction is oblique to the circumferential direction. Preferentially, the direction-dependent rigidity is realized with a waving or crimping. Through this alignment, which is arranged oblique to the tire circumference, the stabilizing effect of the waving is seen in both the longitudinal as well as the oblique directions. Thus, in comparison with the usual belted tires, less material is needed in tire production, and these tires are both light, but nevertheless possess good driving characteristics and superb rolling resistance.

Abstract: A pipe coupling is disclosed which is capable of being periodically coupled and uncoupled between two lengths of pipe. The pipe coupling includes a first and a second union which are fixed between an intervening length of pipe such that the intervening length of pipe does not have to be of a precision length. The outer periphery of one end of the pipe contains serrations and this end is fixed to the first union by a serrated compression ring and a backnut. By tightening the backnut onto the first union, the compression ring firmly engages the serrations on the pipe and prevents axial movement thereof. The second union includes a non-binding compression ring and a backnut as well as having an internal elongated bore of approximately the same diameter as the outer diameter of the pipe. As the backnut is tightened onto the second union, the compression ring is squeezed about the outer periphery of the pipe and forms a seal therewith. One benefit of this second union is that it can be repeatedly coupled and uncoupled relative to the pipe to permit the intervening length of pipe to be moved into or out of the second union as the need arises. The second union also permits a tight seal to be formed even when a limited amount of misalignment exist between the pipe and the second union.

Abstract translation: 公开了一种能够在两段管道之间周期性地联接和分离的管接头。 管接头包括第一和第二接头，其固定在中间长度的管之间，使得管的中间长度不必具有精度长度。 管的一端的外周边包含锯齿状，该端部通过锯齿状的压缩环和盘簧固定在第一接头上。 通过将螺母拧紧到第一接头上，压缩环牢固地接合管道上的锯齿并防止其轴向移动。 第二联合体包括无约束力的压缩环和底盘以及具有与管的外径大致相同直径的内部细长孔。 随着将螺母紧固到第二接头上，压缩环围绕管的外周被挤压并与其形成密封。 该第二联合体的一个好处是可以相对于管道重复地联接和分离，以允许管道的中间长度根据需要移入或移出第二联合。 即使在管道和第二联管之间存在有限量的不对准的情况下，第二联管也允许形成紧密的密封。

Abstract: A foldable rollover protection system, or ROPS, is equipped with a lever to assist in raising and lowering the ROPS, without the necessity of the operator leaving the vehicle seat. The lever is slidably mounted in a guide on the upper, folding, part of the ROPS to allow it to slide out of the way when not in use. Appropriate holes are provided in the pivot bracket into which a pin can be inserted to lock the ROPS in its raised or lowered positions. A spring clip is provided which can hold the pin in place in either set of holes.

Abstract: A plug connector set-up for a control unit includes: a pin support having a pin; and a guide element having a lead-through for positioning the pin at a circuit board of the control unit. The lead-through has an entrance opening on the side facing the pin support and an outlet opening on the side facing away from the pin support. A diameter of the entrance opening is greater than a diameter of the outlet opening. The pin includes a centering region having a diameter which is less than the diameter of the entrance opening and greater than the diameter of the outlet opening.
