The invention is a conveying wire with disc-shaped conveying members for use in endless tube conveyor systems. A status report periodically received from each of a plurality of network appliances is recorded. The system 98 further includes means for allowing the user to start and stop the processing of the measured finger motion by moving the finger with sensor ring 100 thereon a predetermined distance and speed. The feedback loop loops back to the input a feedback signal which depends on an output signal present at the output. The hydrocarbon fraction is isomerized to improve cold flow properties.
