    • A system for monitoring a machine tool under automatic control is provided which uses the actual path of the tool in all directions of motion for comparison with a mathematically ideal path to detect tool error. Machine tool position is obtained from independent feedback devices on each axis of tool movement. The system monitors the machine control commands independently of a machine control command generating means, the machine control command generating means commonly bring a computer of a conventional type. Thus, a monitoring loop is placed about the entire machine tool, that loop being capable of detecting malfunction or mispositioning of the tool, as that tool operates under automatic control. An independent dynamic braking means enables the system of this invention to bring the machine to a stop without part scrappage in the event of a machine shut down, occurring for example, because of a power system failue, or mispositioning error detection.
    • 提供了一种用于在自动控制下监视机床的系统,其使用工具在所有运动方向上的实际路径与用于检测工具误差的数学理想路径进行比较。 机床位置由刀具运动各轴上的独立反馈装置获得。 该系统独立于机器控制命令生成装置监视机器控制命令,机器控制命令生成装置通常带有常规类型的计算机。 因此,围绕整个机床设置监控回路,该回路能够检测到工具的故障或错位,因为该工具在自动控制下运行。 独立的动态制动装置使本发明的系统能够在机器停机的情况下使机器停止,例如由于电力系统故障或误位错误检测而发生。

    • Springs and straps laterally and vertically buttress lateral buttock support wings of a motorcycle seat. The springs are flat and sinuous and extend slightly upward and outward from the seat pan to support the seat wings. Straps secure to the springs and pass inwardly from them through a hole in the pan to an anchor point for the straps underneath the pan. The length of the straps is adjustable to adjust the lateral distance between the springs in the wings and the response to force applied to the springs. The straps restrain the springs in their spreading under rider load. The looser the straps the more the springs deflect vertically and laterally under rider load.
    • 横向和纵向的弹簧和肩带支撑侧面臀部支撑摩托车座椅的翼。 弹簧是平的和弯曲的,并且从座盘向稍微向上和向外延伸以支撑座椅翼。 皮带固定在弹簧上,并从它们的内部通过锅中的一个孔向内移动到平底锅下的皮带的锚固点。 带的长度是可调节的,以调节翼中的弹簧之间的横向距离和对施加到弹簧的力的响应。 带子限制弹簧在骑手负载下的传播。 松紧带的弹簧越多,弹簧在骑手负载下垂直和横向偏转。
