摘要： A data communication system for use in downhole applications wherein electrical energy is supplied over a multiple-conductor power cable to an ESP motor assembly. A downhole unit is AC-coupled to the conductors of the power cable through the wye point of the ESP motor assembly. A surface unit is AC-coupled to the conductors of the power cable. Uplink communication of telemetry data occurs over an AC communication scheme supported by the downhole unit and the surface unit. Downlink communication of remote control command data occurs over a different AC communication scheme supported by the surface unit and the downhole unit. These AC communication schemes provide an independent supply of power to the downhole environment. All communication between the surface and downhole environment is accomplished through the power cable without the use of additional communication lines. Data communication is maintained in the event of a ground fault on the power cable.

摘要： At least one three phase driven pumps (56) in a hydrocarbon well (10) well bore (12) uses frequency shift keyed digital signals (78) to pass instructions from a surface station (46, 26, 34, 30) to a tool (14, 76, 56) and reports from a tool (14, 76, 56) to the surface station (46, 26, 34, 30) in common mode through the three phase cables (16) using a star point (58) of the three phase cables (16) after each pump as the signal transmission and reception point and as the point for coupling a DC Power supply (28), also provided in common mode on the three phase cables (16), to the down hole electronic equipment (72 76). The surface equipment (46) and the tool (14) use as a common ground. The digital messages comprises an address portion (80) identifying either the tool (14) for which an instruction (82) is destined or the tool (14) from which a report (also 82) originates. The digital message (18) also comprises a checksum (84) for error identification and correction.

摘要： A fruit juice extractor may include at least one fruit juice extracting assembly for extracting fruit juice and generating a discharge comprising peel oil and frit, and a discharge separation filter positioned below a misfed fruit guide and having a proximal end adjacent the at least one fruit juice extracting assembly and a distal end opposite the proximal end. The discharge separation filter may have a porosity to permit passage therethrough of peel oil while separating the frit, and the discharge separation filter may be positioned at an inclined angle from horizontal so that the distal end thereof sheds frit separated from the discharge. The discharge separation filter permits the peel oil and frit to be separated near the fruit juice extractor assembly instead of downstream therefrom.
