Title: Torque-turn system for a three-element sucker rod joint
Inventor: NEWMAN FREDERIC M
IPC: E21B19/16
Filed: 2001-10-26
Abstract: A sucker rod tool system for oil wells monitors both torque and angular displacement of a three-element sucker rod connection. The tool system engages two sucker rods that are at least partially screwed into opposite ends of a sucker rod coupling. The system, however, does not engage the coupling adjoining both rods. The system determines whether a connection has been properly tightened by sensing the torque and angular displacement of the connection as it is being tightened, and comparing the data to a stored reference set of data or curves. In some embodiments, a properly tightened connection is based upon the number of straight lines that are needed to adequately approximate a plotted curve of the sensed torque versus angular displacement. Tightness of each connection of a string of sucker rods is recorded with reference to each connection's depth within a well to later serve as an aide in diagnosing connection failures. In some cases, the energy required to unscrew a connection is also recorded. In some embodiments, the system automatically determines whether one or both sucker rods of a three-element connection need to be tightened.

Abstract: A method and system manages and controls the download of programming, i.e., code objects, to a set-top terminal connected to a cable television system so as to prevent disruptions to service that may arise if only some of the objects specified are successfully downloaded and might, therefore, function improperly or conflict with existing applications. When the message to download new or additional code objects lists two or more objects to be acquired, the set-top terminal will only enable and execute downloaded objects if all the listed objects are successfully acquired. If only some of the objects the terminal has been instructed to download are acquired, those downloaded objects may either be purged or stored in memory without being enabled and executed. The system operator may specify in the message instructing the terminal to acquire new objects, whether the listed objects must be implemented as a group or not at all. The system operator may similarly specify if objects from an incomplete download are to be purged from memory.
