    摘要: In a process for applying a friction-resistant coating to a steel sucker rod, the rod is passed, in sequence, through a surface preparation stage (for example, scale removal, shot peening, or other suitable method), an adhesive application stage (to enhance the strength of the coating's bond to the rod), an extrusion stage (in which the rod is passed through a die in conjunction with a flow of melted polymeric coating material), and a cooling (coating solidification) stage. Typically, the radial thickness of the coating will be between 0.125 and 0.375 inches. The process is adaptable to apply extruded coatings to continuous rod or to individual sucker rods having upset ends. The coating may be selected from but is not limited to high-density polyethylene, cross-linked polyethylene, polyvinylidene fluoride, ethylene tetrafluoroethylene, polytetrafluoroethylene, polyphenylensulfide, nylon, polyester, polyethersulfone, polyethylene terephthalate, polypropylene, polystyrene, epoxy, or acetyl.

    摘要: An optical module includes a first optics group, a second optics group, and an image sensor, wherein the first optics group and second optics group are configured to provide an image having a focus and a magnification to the image sensor. In some embodiments of the present invention, a first optics assembly includes a first optics group coupled to a threaded portion of a first lead screw so that rotation of the first lead screw results in translation of the first optics group along an axis of the first lead screw, a first actuator for rotating the first lead screw; and a first sensing target configured to permit detection of rotation of the first lead screw. In some embodiments of the present invention a second optics assembly includes a second optics group coupled to a threaded portion of a second lead screw so that rotation of the second lead screw results in translation of the second optics group along an axis of the second lead screw, a second actuator for rotating the second lead screw, and second means for sensing configured to detect rotation of the second lead screw.
