20120186818 | Sucker Rod Coupling and Method of Wear Prevention in Driven Rotation of a Sucker Rod String in Production Tubing - A sucker rod coupling features a coupler unit having internally threaded coupling sections at opposite ends for engaging sucker rod pins and one or two outer members extending about the coupler unit between the ends, each outer member being rotatable about the coupler unit and presenting contact surfaces facing outwardly at positions radially outward therefrom. Each outer member is positioned between a respective end of the coupler and a stop defining feature thereof, and a respective stop element is selectively deployable adjacent the respective end of the coupler on a side of the outer member opposite the stop-defining feature. The outer member prevents wear to the production tubing and the sucker rod string, is easily replaceable through manipulation of the stop element to allow sliding of the member off the unit and sliding of a new member thereon, and directly engages the sucker rods without needing additional threaded components. | 07-26-2012 |
20130101380 | Rod Clamping Devices for Hanging or Pulling Rod Strings in a Wellbore - Clamping devices for hanging or pulling wellbore rod strings each feature housing with an axial bore in which a number of clamping pieces are placed to wedge in place between the housing and rod string to perform a self-tightening action against the rod string under the weight thereof due to cooperation of beveled surfaces at the bore wall and exterior of the clamping pieces. Threaded fasteners fed through the housing wall aid in placement of the slips against the rod string. For use in pulling operations, the housing is sized for receipt in the latching mechanism of a tubing elevator for support by the same, whereby the tubing elevator can be used to pull out a stuck rod string. Some embodiments feature a circumferential gap in the housing to enable the housing to be slipped laterally onto the rod string. | 04-25-2013 |
20140116725 | Tubular Member Coupling and Lining Systems and Methods - For use in assembling a tubing string for a production well, a rigid pre-formed liner is configured for simple drop-in place installation at each tubing joint during assembly of the tubing string in to protect the inside of the tubing string from wear caused by operation of a sucker rod inside the same. At a threaded connection in the finished tubing string, where an externally threaded top end of a section of production tubing is engaged with an internally threaded bottom end of a box coupler or collar, the tubular portion of a respective liner hangs downward from a larger-diameter collar portion of the liner that sits atop the annular top end of the section of production tubing. The liner is installed by simply dropping its tubular portion into the section of tubing and then threading the box coupler onto the section tubing around the upper end of the liner. | 05-01-2014 |

20100182189 | DEVICE AND METHOD FOR DETECTING NON-LINEAR ELECTRONIC COMPONENTS OR CIRCUITS ESPECIALLY OF A BOOBY TRAP OR THE LIKE - The invention relates to a device and a method wherein tunable transmitters and detectors (receivers) are integrated into a non-linear detection system and a narrow-band signal having a variable frequency is used. The scanable frequency range should be between 10-100 MHz. The frequency acceptance range for the second and third harmonic is adjusted according to the transmit frequency. | 07-22-2010 |
20100289686 | METHOD FOR PERMANENT DISTURBANCE/DESTRUCTION OF ELECTRONICS, IN PARTICULAR OF A BLAST CASE OR THE LIKE - In a first step, it is proposed that tunable transmitters and detectors (receivers) be included in a detection system and that a narrowband, preferably variable frequency signal be used in order to determine the frequencies for optimum injection into the electronics of a target. When the detection system identifies these frequencies, destruction can be initiated in the second step of the invention for a transmitter or receiver which is communicating with the target. For this purpose, once the optimum frequencies have been determined, a high-power signal is transmitted into the local area of the target at the specific/determined frequency. The evaluation unit, which is integrated in the detection system, controls the transmission frequencies, evaluates the harmonic signals, selects the optimum frequencies for an attack, and controls and checks the attack process. | 11-18-2010 |
