Abstract: A new computerized tracking system, IndeliTrak, that incorporates the state-of-the-art technologies including cell phones, GPS, Internet, and scanners to gather and distribute up-to-the-minute tracking data with little effort. As an example, a courier carries a mobile phone that is attached to a barcode scanner and programmed with IndeliTrak's tracking software. The mobile phone enables the courier to log in, retrieve his service schedule, verify each service location, log arrival/departure time, scan packages for pickup and delivery, and sign off. Scanned data are stored on the phone and transmitted to a customized IndeliTrak database. End users can track the packages via IndeliTrak's browser-based user interface almost instantaneously. IndeliTrak does not require unique package identifications (IDs) or barcodes. Acceptable IDs include radio frequency identification (RFID) tags, non-serialized barcodes, electronic product codes (EPCs), etc. The same ID code can be reused daily.

Abstract: In the process according to the invention for the aqueous suspension polymerization of vinyl chloride, alone or as a mixture with another vinyl monomer, the polymerization initiator comprises at least one compound chosen from dialkyl peroxydicarbonates, peroxy-tert-alkanoates and diacyl peroxides and use is made, as agent for halting the polymerization, of a mono- or disubstituted hydroxylamine. The resins thus obtained exhibit improved color and heat stability.
