摘要： A binder consisting of an aromatic polymeric material in which aryl groups are connected together by single-bond linkages over one or more atoms of carbon, sulfur, oxygen, nitrogen, phosphorus or silicon, preferably polyphenylene-sulfide, is mixed with carbon particles, with or without the addition of copper powder and the mixture is then pressed in a mold, removed from the mold, and sintered at a temperature of 300-500.degree.C, preferably about 350.degree.C for about an hour. Even without the presence of metal powder such brushes have qualities comparable to brushes cut from carbon plate material and conventional copper-containing brushes, and have substantially longer life than the former.
摘要翻译：由芳族聚合物材料组成的粘合剂，其中芳基通过碳键，硫，氧，氮，磷或硅（优选聚苯硫醚）的一个或多个原子上的单键键连接在一起，与碳颗粒混合，或者不加入铜粉末，然后将该混合物压在模具中，从模具中取出，并在300-500℃，优选约350℃的温度下烧结约1小时。即使不存在金属粉末，这样的刷子也具有与碳板材料和常规含铜刷子切割的刷子相当的质量，并且具有比前者更长的寿命。

摘要： Insulation between a rotor shaft and slip rings for electrical connection to a rotary winding is provided by a layer coating the shaft that is sintered in place from fluidized bed material, providing a thin layer that is sufficiently tough for slip rings to be mounted on top so that the layer provides the insulation from the shaft. The slip rings may be quite thin, thus keeping the active surface of the slip ring to a very small diameter. Brass and bronze slip rings may be press-fitted onto the shaft while maintaining the insulation of the layer, but carbon slip rings, which are desirable for long life are best secured by means of an adhesive. The slip ring assembly is particularly useful for three-phase alternators of motor vehicles.
摘要翻译：用于与旋转绕组电连接的转子轴和滑环之间的绝缘通过涂覆从流化床材料烧结就绪的轴的层提供，从而为滑环安装在顶部提供足够坚硬的薄层该层提供了与轴的绝缘。滑环可能相当薄，从而将滑环的活动表面保持在非常小的直径。黄铜和青铜滑环可以压在轴上同时保持层的绝缘性，但是长寿命所需的碳滑环最好通过粘合剂来保证。滑环组件对于机动车辆的三相交流发电机特别有用。
