摘要： A fiber reinforced polymer beam may be manufactured by winding one or more strands of resin coated fibers about four pins mounted upon a winding fixture, each pin being independently translatable along the winding fixture and being independently extendable into, and retractable out of, the winding fixture. As the fiber is wound around the two exterior pins the interior pins will retract and translate to positions exterior of the pins being wound and will then extend to receive the next wrap of fiber. As the exterior pins are wound the interior pins continue to be translated to a position outside of the pins being wound so as to be in position to receive the next wrap of the fibers.
摘要翻译：纤维增强聚合物束可以通过缠绕一根或多根树脂涂覆的纤维缠绕在绕组夹具上的四个销钉来制造，每个销可以沿着卷绕夹具独立地平移，并且可独立地延伸到卷绕夹具。当纤维缠绕在两个外部销上时，内部销将缩回并且平移到被缠绕的销的外部位置，然后延伸以接收下一个纤维包裹。当外部引脚被缠绕时，内部引脚继续被平移到被缠绕的引脚外侧的位置，以便接收纤维的下一个包裹。

摘要： Method and device for enhancing the adhesion qualities of vehicle wheels through the use of a plurality of embedded members having exposed high frictional surfaces, which are capable of automatically being caused to attain frictional contact with a wheel bearing surface in response to slippage. Under normal conditions where enhanced friction is not needed, the embedded members lie in a relative retracted position from which they may respond to slippage conditions as needed.
摘要翻译：通过使用具有暴露的高摩擦表面的多个嵌入构件来提高车轮的附着质量的方法和装置，其能够自动地响应于滑动而与车轮支承表面摩擦接触。在不需要增强摩擦的正常条件下，嵌入构件处于相对缩回的位置，根据需要它们可以响应于滑动条件。
