Abstract: Title of the Invention DATA COMMUNICATIONS SYSTEM WITH IMPROVED DIGITAL PHASE-LOCKED LOOP RETIMING CIRCUIT Abstract of the Disclosure A digital timing recovery circuit is disclosed for synchronously transmitting digitally encoded data in a multiterminal configuration between a data processor and a plurality of data terminals associated therewith.  Phase shifted synchronous data from the data processor is continuously com-pared with a newly generated synchronous clock generated at a repeater interposed along the communication line for minimiza-tion of the time differential between the retiming clock and the transmitted data.  The data transitions enable a digitally implemented one-shot, which generates pulses, the leading edges of which pulses enable a difference counter, while the leading edges of the retiming clock pulses disable the counter.          The difference counter output is sampled in a digital phase locked loop to derive the number of cycles of a stable oscillator which occur between the two aforementioned leading edges of the generated pulses.  A difference of less than a predetermined count such as two, results in no correction of the retiming clock, a difference count greater than such predetermined amount, such as a count of three through seven, advances the clock by adding a pulse to the retiming clock, and 8 difference of more than a predetermined number of counts, such as eight, retards the clock by subtracting a pulse from the retiming clock.  Thus, continuous digital adjustment of the synchronous clock is provided to maintain the counter difference below a predetermined count, such as two, which serves to resynchronize bit-shifted data with the retiming clock for retransmission into the communications channel.

Abstract: ABSTRACT FOR CANADA          Spray drying process and apparatus for producing fibres, especially polycrystalline inorganic fibres such as alumina, from viscous aqueous sols or solutions, optionally with the use of a linear organic polymer spinning aid such as poly-ethylene oxide.   The preferred atomiser is a rotating disc atomiser which may have grooves in the disc vanes.   The interior of the atomiser may be supplied with cold humid air to prevent premature solidification of the feed liquid which leads to shot formation.   Hot air for drying the fibres is preferably introduced tangentially on to the interior wall of the drying chamber and away from the atomiser, and in the same direction as fibres are formed from the atomiser.          Fibres having mean diameters above 1 micron and less than 5 microns and virtually free from shot (non-fibrous material) can be produced.
