Abstract: A mixture which comprises an organic amide solvent and a sulfur source comprising an alkali metal hydrosulfide and optionally contains part of the whole alkali metal hydroxide to be introduced is heated to conduct a dehydration step. The mixture remaining in the system after the dehydration step is mixed with a dihaloaromatic compound. The resultant mixture is heated to polymerize it and, simultaneously therewith, an alkali metal hydroxide is continuously or portion-wise added to the polymerization reaction mixture to regulate the pH of the polymerization reaction mixture to 7 to 12.5 throughout the period of from the initiation to the termination of the polymerization. The polyarylene sulfide has a nitrogen content of 800 ppm or lower.

Title: Robust mode staggercasting user controlled switching modes
Inventor: BOYCE JILL
IPC: H04N21/438

Abstract: A method and apparatus for staggercasting includes encoding a set of signals representing content. The set of encoded signals (115) is capable of being decoded to produce a corresponding set of decoded signals (output of 210), each having a quality which is different from the qualities of the decoded signals corresponding to the other encoded signals. A composite signal (115 or 205) is generated which includes the set of encoded signals, staggered in time. The set of encoded signals extracting from the composite signal. Errors in the set of extracted encoded signals are detected (E) to produce a subset of available extracted encoded signals which are not erroneous. A content representative signal (215) at a selectable desired quality is then decoded.
