Title: Composition for shortstopping free radical emulsion polymerizations and stabilizing latices made therefrom
Inventor: LOU JIANFENG
IPC: C08F2/24
Filed: 2001-03-02
Abstract: Disclosed are compositions for shortstopping free radical emulsion polymerizations and stabilizing polymers produced from the corresponding emulsion processes. Such compositions include at least one hydrophillic radical scavenger (i.e, shortstopper)and at least one hydrophobic radical scavenger. The compositions are preferably targeted for applications in the emulsion processes of rubber latexes. These compositions exhibit excellent performance not only as shortstoppers of free radical emulsion polymerizations but also as stabilizers of the corresponding polymers. Thus, the compositions prevent additional polymerization in the particles without requiring additional stabilizer even after such polymers are steam stripped. They do so without the use of chemicals which carry a high safety, health, or environmental risk.

The first unit is programmed to produce a command sequence, preferably comprising a series of DC voltages applied to the tip and ring leads, and received at the second unit. The second unit is programmed to recognize the series of DC voltages and begin transmitting the test signal. The second unit is preferably able to signal the first unit to begin a test sequence by drawing a DC current through the tip and ring leads for a predetermined period of time, which is recognized by the first unit. The second unit is further adapted to be a passive device, and to have an energy storage device to provide power to the unit during transmission of the command sequence.

Title: System and method for prioritizing traffic channel messages
Inventor: YEGANI PARVIZ
IPC: H04L12/851
Filed: 2000-03-31
Abstract: A system and method places signaling message frames in a traffic channel carrying voice frames so that the signaling message transmission does not seriously impact voice quality. This is accomplished by producing a first stream of voice encoded packets and a second stream of signaling message packets. The signaling message packets are prioritized in the second stream relative to the voice encoded packets in the first stream. An arbitration element arbitrates between the voice encoded and prioritized signaling messa ge packets, which are multiplexed as a function of this arbitration. The multiplexed voice encoded and prioritized signaling message packets are then  transmitted.
