摘要： A threaded connection assembly comprises a nut, a multiplier connected to the nut via a first threaded interface having a first number of threads per inch and a well servicing pipe coupling connected to the multiplier via a second threaded interface having a second number of threads per inch. A method of forming a threaded connection for a well servicing application comprises forming a pipe coupling between two well servicing pipe sections and threading a connector to the pipe coupling to form a threaded connection without impact loading the connector. Another method for forming a threaded connection comprises disposing a first pipe section partially within a nut, threading a multiplier into the nut, threading the multiplier onto a second pipe section, and leveraging the multiplier against the nut, or vice versa.

摘要： An apparatus for rotating a threaded tightening device includes a guide and an anvil utilized to impact a lug on the threaded tightening device to rotate the tightening device onto or off of a threaded member. The guide has a frame with a support sleeve attached thereto. A reciprocating device is received in and is supported by the support sleeve. The anvil is attached to the reciprocating device. When the reciprocating device is received in and is supported by the support sleeve, actuation of the reciprocating device will cause the anvil to repeatedly impact a lug to rotate the threaded tightening device in the desired direction.

摘要： A hydrodynamic pad including fluid-filled inner and outer bladders interconnected by fluid channels and configured such that displacement of fluid from the center of pressure distribution generated by foot impact radiates from the inner bladder outwardly to the outer bladder through one or more of the fluid channels causing the outer bladder to expand to an expanded condition. The expanded outer bladder seats the wearer's heel in the hydrodynamic pad, thereby stabilizing the foot of the wearer, and the controlled flow of fluid through the fluid channels to the outer bladder dissipates the impact loads, thereby cushioning the wearer's heel. When the pressure is released from the inner bladder, by lifting the wearer's heel, the expanded outer bladder forces at least a portion of the displaced fluid to the inner bladder, such that the hydrodynamic pad is reinitialized.
摘要翻译：一种流体动力垫，其包括通过流体通道互连的流体填充的内部和外部气囊，并且构造成使得流体从脚部冲击产生的压力分布中心的位移通过一个或多个流体通道从内部气囊向外辐射到外部气囊导致外囊膨胀到扩张状态。膨胀的外囊在水动力垫中安放穿用者的脚后跟，从而使穿着者的脚稳定，并且流体通过流体通道受到控制的流动到外囊消耗冲击负荷，从而缓冲穿着者的脚后跟。当压力从内囊释放时，通过提升穿着者的脚跟，膨胀的外囊将迫使流体动力垫重新初始化的位移流体的至少一部分迫使内囊。
