Abstract: Hydrocarbons are produced from a wellbore using a wand member supported within the top end of the casing and a bailer vessel supported within the casing of the wellbore to reciprocate between (i) a lower position submerged in the hydrocarbon fluids at a predetermined depth within the casing such that fluids enter a production chamber of the bailer vessel and (ii) an upper position receiving the wand member therein through an open top of the bailer vessel so as to force the hydrocarbon fluids in the production chamber under pressure through a bottom opening in the wand member and into a receiving chamber of the wand member. The hydrocarbons in the wand member are then discharged to a location externally of the casing for storage.

Abstract: A motor and pump assembly for use in a wellbore includes a downhole motor producing a rotary output, a reciprocating plunger for pumping fluid up a tubing string, and a drive linkage supported within the hollow tubular housing having a rotary input in connection with the rotary output of the motor and a reciprocating output which is arranged for longitudinal sliding movement with the reciprocating plunger and which is driven responsive to rotation of the rotary input to drive the plunger. The drive linkage includes a lead screw, a sleeve member having a closed end coupled to the plunger, and a follower supported on an inner side of the sleeve member in operative connection to the lead screw to drive longitudinal sliding movement of the sleeve member responsive to rotation of the lead screw.

Abstract: A method of providing proof of authenticity for an item of merchandise to the portable device of a potential buyer is disclosed. The method utilizes (i) affixing or embedding a token that provides a unique merchandise authentication code that is readable by the buyer's portable device (the code may be on a contactless microprocessor chip), (ii) including this merchandise authentication code in messages that comprise conventional card-based payment transactions, (iii) providing the potential buyer's portable device with data pertaining to the lifecycle status, authenticity, and description of the item of merchandise, (iv) displaying the data at the buyer's portable device, and (v) posting/recording the sale of the item of merchandise at the brandname lifecycle management host.

Abstract: Disclosed herein is a method of producing an instrumentation interface. The method includes the steps of receiving instrument data to be depicted via an indicator of the instrumentation interface, processing the instrument data to determine a motion trail for the indicator, and generating the instrumentation interface with the indicator and the motion trail. In some embodiments, the processing step includes generating a low-pass filtered representation of the received instrument data. To that end, the received instrument data may be applied to a cascaded pair of low-pass filters.
