    • A down hole drill, includes a drill bit (40), a reciprocating piston (75) operable to deliver an impact load to the drill bit, and means for changing the frequency with which the piston delivers impact loading to the drill bit, also resulting in a change in overall power of the drill. The means for changing frequency and overall power may operate during continuous operation of the drill. The means for changing the frequency and overall power may include a valve (130) for selectively changing the effective volume of a drive or return chamber, an actuator (140) for changing the timing of placing the drive (25) or return chamber (30) in communication with exhaust (95), or a system for changing the frequency in response to sensing an predetermined operating parameter of the drill, such as pressure or piston position.
    • 井下钻具包括钻头(40),可操作以将冲击载荷传递到钻头的往复式活塞(75),以及用于改变活塞传递冲击的频率的装置 装载到钻头上,也会导致钻机的总功率发生变化。 用于改变频率和整体功率的手段可以在钻机的连续操作期间运行。 用于改变频率和总功率的装置可以包括用于选择性地改变驱动或返回腔室的有效容积的阀(130),用于改变驱动器(25)或返回腔室(30)的放置时间的致动器(140) )与排气装置(95)连通,或者响应于检测到钻头的预定操作参数(例如压力或活塞位置)而改变频率的系统。

    • The present disclosure features tube insertion devices that are configured to allow a user to manually insert a hollow tube into a receiving bore, e.g., a pen tube into the bore of a blank. The disclosure also features methods of using such devices. In some implementations, the devices comprise (a) a pair of elongated arms, each arm comprising a gripping portion and an insertion portions, each of the insertion portions terminating in a distal tip, and (b) a connecting portion joining the arms such that the arms pivot about the connecting portion in a plane defined by the arms when the gripping portions are pressed together by a user. Each of the insertion portions preferably includes a relatively wider proximal portion and a relatively narrower distal tube-carrying portion, the change in width between the proximal portion and the distal portion defining a stop surface.
    • 本公开的特征在于,管插入装置被配置为允许使用者手动地将中空管插入容纳孔中,例如将笔管插入坯件的孔中。 本公开还具有使用这种装置的方法。 在一些实施方案中,装置包括(a)一对细长臂,每个臂包括夹持部分和插入部分,每个插入部分终止于远侧末端,和(b)连接臂连接部分,使得 当把手部分被使用者压在一起时,臂在由臂限定的平面中围绕连接部分枢转。 每个插入部优选地包括相对较宽的近端部分和相对较窄的远端管道承载部分,所述近端部分和远侧部分之间的宽度变化限定止动表面。
