    • A braiding-machine strand-guide arm has an outer end provided with a strand guide and an inner end formed as a pivot eye. The arm further has a body formed of spaced-apart outer layers of a hard material and a very low-density mass between the outer layers. The outer layers are formed of a plastic laminate reinforced with fibers of carbon, glass, boron, or metal. Whisker fibers can also be used as reinforcement. Preferably the laminate includes textile reinforcement. Alternately the hard material of the shell of the arm can be made of cast metal. The low-density mass is normally a solid material. It is a foamed plastic, typically a light polyurethane foam.
    • 编织机绞线引导臂具有设置有线引导件的外端和形成为枢轴眼的内端。 臂还具有由外部层之间由硬质材料隔开的外层和非常低密度的质量形成的主体。 外层由用碳,玻璃,硼或金属纤维增强的塑料层压板形成。 晶须纤维也可用作增强材料。 优选地,层压体包括织物加强件。 或者,臂的壳的硬质材料可以由铸造金属制成。 低密度质量通常是固体材料。 它是泡沫塑料,通常是轻质聚氨酯泡沫。

    • A drive mechanism for driving one or a plurality of displaceable elements around a closed path, such as a circle, constituted by a linear induction actuator associated with means for constraining the displaceable elements to move in the closed path. A capacitive feedback control system determines the position of the element or elements around the path and controls the windings of the linear induction actuator in dependence on an error signal generated therefrom. An open path drive mechanism having a plurality of linear induction actuators and a capacitive feedback control system is also encompassed by the invention as are hybrid linear induction motors using sets of arcuate linear induction actuators around the rim of a reaction member which drives an output shaft of the motor.
    • 驱动机构,用于驱动一个或多个位移元件围绕诸如圆圈的闭合路径驱动,该线性感应致动器由与用于限制可移动元件在闭合路径中移动的装置相关联的线性感应致动器构成。 电容反馈控制系统确定元件围绕路径的位置,并且根据由其产生的误差信号控制线性感应致动器的绕组。 具有多个线性感应致动器和电容反馈控制系统的开放路径驱动机构也包括在本发明中,混合式线性感应电动机是使用围绕反作用构件的边缘的弓形线性感应致动器组,其驱动输出轴 电机。
