摘要： A motion control system for hydraulically operated lifting devices. The system provides for the dynamic weighing of a loaded container by controllably directing hydraulic flow through a bypass chamber of a two-way valve. An analog output signal is generated by a hydraulic pressure transducer fluidly communicating with the two-way valve or by a tensiometer mounted on the arms of the lifting device. The two-way valve further provides a second bypass chamber which receives fluid under gravity from the lift circuit line of the hydraulic cylinder for controllably lowering the lifting device. The pressure transducer or tensiometer generate an analog signal proportionate to the weight being lowered and whereby the hydraulic fluid is returned to the reservoir of the hydraulic system independently and downstream of the main operating valve.
摘要翻译：一种用于液压操作提升装置的运动控制系统。该系统通过可控地引导液压流动通过二通阀的旁路室来为装载的容器进行动态称重。模拟输出信号由与双向阀或安装在提升装置的臂上的张力计流体连通的液压传感器产生。双向阀进一步提供第二旁路室，其在重力作用下从液压缸的提升回路线接收流体，用于可控地降低提升装置。压力传感器或张力计产生与被降低的重量成比例的模拟信号，由此液压流体独立地在主操作阀的下游返回到液压系统的储存器。

摘要： A paint tinter system includes a plurality of canisters disposed in a circle about a rotatable plate. An orbiting plate, driven by a single motor, is connected to drive arms, each of which is connected to a crank arm of a stirrer in one of the canisters. The connection is made through a lost-motion device in a cap covering each canister. The cap captures the end of the drive arm, whereby the cap may be removed and hinged out of the way for providing access to the canister. An impeller is freely mounted for rotation in a socket in the bottom of the canister. The upper end of the impeller is driven by engagement between a pair of driver bosses rotated by the crank and edges of a top plate on the canister. Thus, when the cover is removed, the impeller may remain unmoved or be lifted from the socket for cleaning.
摘要翻译：油漆调色剂系统包括围绕可旋转板设置成圆形的多个罐。由单个电动机驱动的旋转板连接到驱动臂，每个驱动臂在其中一个罐中连接到搅拌器的曲柄臂。连接通过覆盖每个罐的盖中的丢失运动装置进行。盖帽捕获驱动臂的端部，由此盖子可以被移除并铰接在一起以提供对罐的通路。叶轮可自由地安装在罐的底部的插座中旋转。叶轮的上端由通过曲柄旋转的一对驱动器凸台和罐上的顶板的边缘之间的接合来驱动。因此，当盖子被移除时，叶轮可以保持不动或从插座上抬起以进行清洁。
