    • A liner string for a well has a liner hanger assembly at an upper portion of the liner string. A profile sub is located at a bottom portion of the liner string. A bottom hole assembly is latched to the profile sub. The operator lowers the liner string into the well with a drill pipe string and rotates the drill pipe string to rotate the drill bit to deepen the well. At a selected depth, the operator releases the bottom hole assembly from the profile sub and reverse circulates drilling fluid from a liner annulus surrounding the liner string, pumping the bottom hole assembly up the liner string. When the bottom hole assembly reaches the lower end of the drill pipe string, it latches to a catcher tool located at the lower end of the drill pipe string. The operator moves the liner hanger assembly into setting engagement with the casing string, releases the drill pipe string from the liner string, and retrieves the drill pipe string along with the bottom hole assembly.
    • 用于井的衬管串在衬套柱的上部具有衬垫悬挂器组件。 轮廓子部分位于衬垫弦的底部。 井底组件被锁定到轮廓子。 操作员将钻柱降低到钻井管柱中并旋转钻杆柱以旋转钻头以加深井。 在选定的深度处,操作者从型材中释放底孔组件,并使钻井液从围绕衬管柱的衬套环向后循环,将底孔组件向上泵送衬套柱。 当底孔组件到达钻杆柱的下端时,它锁定到位于钻杆柱下端的捕集器工具。 操作者将衬管悬挂器组件移动到与套管柱的设定接合中,从钻柱排出钻杆柱,并与钻孔组件一起取回钻杆柱。

    • The child receiving device includes a seat, seat suspension arms for supporting the seat portion, and a support frame for supporting the seat suspension arms and the seat above a supporting surface. Two front seat suspension arms are pivotally connected at their lower ends to opposite front ends of the seat and two rear seat suspension arms are pivotally connected at their lower ends to opposite rear ends of the seat. The support frame includes a suspension guide, the upper ends of the front and rear seat suspension arms being pivotally connected to the suspension guide. The suspension guide includes a slot along which the upper ends of the front seat suspension arms may be moved toward and away from the upper ends of the rear seat suspension arms. The distance between the upper ends of the front seat suspension arms and the upper ends of the rear seat suspension arms is adjustable to convert the child receiving between a swing configuration (providing a traditional arcuate swinging motion to the child seat) and a glider configuration (providing a front-to-back, quasi-linear, translational movement to the child seat).
    • 儿童接收装置包括用于支撑座椅部分的座椅,座椅悬挂臂,以及用于将座椅悬挂臂和座椅支撑在支撑表面上方的支撑框架。 两个前排悬挂臂在其下端枢转地连接到座椅的相对的前端,并且两个后座椅悬挂臂在其下端枢转地连接到座椅的相对的后端。 支撑框架包括悬挂导向件,前后座椅悬挂臂的上端可枢转地连接到悬架导向件。 悬挂引导件包括一个狭槽,前排座椅悬挂臂的上端沿着该槽可以朝向和远离后座椅悬挂臂的上端移动。 前座椅悬挂臂的上端与后座椅悬挂臂的上端之间的距离是可调节的,以便在摆动构型(向儿童座椅提供传统的弧形摆动)和滑翔机构型之间转换儿童接收 为儿童座椅提供前后,准线性,平移运动)。
