摘要： A well-pressure operated pump having a tubular pump body provided with an interior, annular seating surface to receive a valve member mounted on a rod extending through the seating surface. An air spring in the pump body urges the rod upwardly in response to fluid pressure in the pump body and the height of the seating surface and the position of the valve member on the rod are adjustable for adjusting the well pressure at which the valve member is seated. Seal assemblies mounted on the pump body are adjustable to match the pump to the internal diameter of the well casing and the seal assemblies are provided with retainer rings having flanges that capture end portions of a sealing member of each seal assembly. A brake, having a plate that is spring loaded to overlay a shoulder in the bore of the pump body, slows the rate of descent of the pump through gases in the well. An aspirator formed in the support for the plate holds the plate off the shoulder during passage of the pump through liquids in the well.
摘要翻译：一种压力良好的泵，其具有管状泵体，其具有内部的环形就座表面，以接收安装在延伸穿过所述座面的杆上的阀构件。泵体内的空气弹簧响应于泵体内的流体压力而向上推动杆，并且座部表面的高度和阀构件在杆上的位置是可调节的，以调节阀构件的井压力坐了安装在泵体上的密封组件是可调节的，以使泵与井套管的内径匹配，并且密封组件设置有具有捕获每个密封组件的密封构件的端部的凸缘的保持环。具有弹簧加载以覆盖泵体的孔中的肩部的板的制动器减慢了泵通过井中的气体的下降速率。形成在板的支撑件中的抽吸器在泵通过井中的液体的过程中将板从肩上保持。

摘要： Disclosed is a transferred arc plasma torch in which a tubular anode is mounted in a bore at the lower end of a barrel of the torch, the bore being formed at a preselected angle to the axis of the barrel. The cathode is a length of tungsten rod which is held in a coaxial relation with the anode by cementing the end of an electrode holder, which mounts the cathode, into an insulating tube which extends through the barrel and forming a silicone rubber sleeve between the insulating tube and a bore formed in lower portions of the barrel such that the sleeve adheres to the insulating tube and the barrel. The silicone rubber sleeve and the cemented connection between the insulating tube and the cathode holder are formed adjacent one end of the anode so that the cemented end of the electrode holder is substantially fixed in relation to the anode. A tapered bore is formed in the electrode holder, coaxially with the anode, and a similar taper is formed on one end of the cathode so that the cathode can be inserted into the bore formed into the electrode holder. Shallow spiral grooves are formed in the tapered portion of the cathode and in the bore in the electrode holder and the tapered portion of the cathode is silver plated to enhance the grip of the electrode holder on the cathode.
摘要翻译：公开了一种转移的电弧等离子体焰炬，其中管状阳极安装在手电筒的下端的孔中，孔以与枪管的轴线成预定角度形成。阴极是钨棒的长度，其通过将安装阴极的电极保持器的端部粘合到延伸穿过筒体的绝缘管中并与绝缘体保持同轴的关系，并在绝缘体之间形成硅橡胶套筒管和形成在筒的下部中的孔，使得套筒粘附到绝缘管和筒体上。绝缘管和阴极保持器之间的硅橡胶套管和接合连接部形成在阳极的一端附近，使得电极夹持器的胶合端部相对于阳极基本固定。在电极保持器中与阳极同轴地形成锥形孔，并且在阴极的一端形成类似的锥形，使得阴极可以插入形成电极夹持器的孔中。在阴极的锥形部分和电极保持器的孔中形成浅螺旋槽，并且阴极的锥形部分被镀银以增强电极保持器在阴极上的抓地力。
