In a spiral tube winder, the plies going to the winding mechanism are monitored to make sure that no ply is broken. Upon sensing a ply break plies are removed from in the glue applying portion of the apparatus and the machine stopped so that broken ply does not become entangled in the apparatus. The ply break detection system (34) is automatically activated for each ply lane that is in use so that...

The invention is a method of determining the acoustic velocity of a drill string (28) in a borehole (10). An acoustic signal is generated at a first location(34) along the drill string, and detected at a second location (7). The detected signal is autocorrelated and the time of occurrence of multipath reflections on the autocorrelation record is utilized to determine acoustic velocity.

A cell including a time stamp, first cell sending rate, first requested cell sending rate is transmitted from a transmitting side to a receiving side. At the receiving side a second cell sending rate is determined based on the first requested cell sending rate, and a second requested sending rate is determined based on the first cell sending rate and the cell discard information. The second reques...
