    • Paper cutting mechanisms for cutting paper in a printing device including a drive mechanism, a cutting device coupled to the drive mechanism, and a retention mechanism including a trigger and a retaining portion configured to mechanically interact with the cutting device to selectively deploy the retention mechanism to retain the paper. In some examples, paper cutting mechanism includes a trigger including an elbow, a first arm extending from the elbow, and a second arm extending from the elbow offset from the first arm, and a rotation shaft extending from the elbow transverse to a plane defined by the first arm and the second arm. In some further examples, the paper cutting mechanism includes a resilient member cooperatively coupled with a paper engaging end of the retaining portion.

    • A grappler for use in grasping and manipulating pipe segments for large diameter pipeline tie-ins has a first frame and a second frame movably secured thereto. A pair of grapple arms is pivotally mounted to each frame and is actuated between a open position and a closed position to engage and grasp the pipe segments. An actuator displaces the second frame relative to the first frame in a first degree of movement to displace one pair of grapple arms relative to the other pair of arms, and a support frame provides the grappler with two additional degrees of movement. When mounted to a backhoe or like device, the grappler facilitates safe retrieval of pipe from hazardous trenches, and provides handling and alignment of the pipe segments for easier and safer welding of the pipe joints.
    • 用于抓取和操纵用于大直径管道连接件的管段的抓斗具有可移动地固定到其上的第一框架和第二框架。 一对抓斗臂枢转地安装到每个框架上并且在打开位置和关闭位置之间被致动以接合和抓住管段。 执行器以第一移动位置相对于第一框架移动第二框架以相对于另一对臂移动一对抓钩臂,并且支撑框架为抓斗提供两个额外的移动程度。 当安装到反铲或类似装置上时,抓斗有助于从危险沟槽中安全地取出管道,并且提供管段的处理和对准以便更容易和更安全地焊接管接头。

    • A method for rehabilitating manholes and other sewer collection system structures begins by repairing existing leaks using hydraulic grout and cleaning the interior surface of the manhole by sandblasting or the like. A waterproofing stage is applied in multiple coats using a crystallization agent that integrates a crystalline structure with the underlying substrate. A chemical attack resistant calcium aluminate cement stage is then applied, and the waterproofing capabilities of the underlying coating are enhanced by the integration of the crystalline structure with the calcium aluminate cement stage. An epoxy coating is applied on the calcium aluminate cement to provide further chemical resistance and waterproofing while simultaneously providing a continuous, bridging barrier during self-repair of cracks in the underlying calcium aluminate by expanding crystallization by the crystallization agent.
    • 修复人孔和其他下水道收集系统结构的方法首先是通过使用液压灌浆修复现有泄漏并通过喷砂等清洁人孔内表面。 使用将晶体结构与底层基底结合的结晶剂在多层涂层中施加防水阶段。 然后施加抗化学腐蚀的铝酸钙水泥阶段,并且通过结晶结构与铝酸钙水泥阶段的整合来增强底层涂层的防水性能。 在铝酸钙水泥上施加环氧涂层以提供进一步的耐化学性和防水性,同时通过使结晶剂膨胀结晶来在底层铝酸钙的裂纹自修复的同时提供连续的桥接屏障。
