IPC: C08G85/00
Filed: 2000-02-17
Abstract: This invention concerns a process for the addition of volatile materials lik e catalysts, stabilizers, plasticizers or comonomers to to prepolymers of e.g.  polyesters, polyamides or polycarbonates prior to or during solid state polymerization processes and the subsequent conducting of said solid state polymerization process. In one embodiment a catalyst like toluene sulfonic acid is introduced into the inert gas stream during solid state polymerizati on of a polyester like polyethylene terephthalate. Alternatively the prepolymer  pellets are contacted with a solution of the volatile material before solid state polymerization.
Patent CA-2359731-A1 (CA)
Title: Method and apparatus for delivering reference signal information within a specified time interval
Inventor: HUANG SI JUN
IPC: H04N7/24
Filed: 2000-01-18
Abstract: Variable rate multiplexer devices have, by definition, a variable output rate for bits of information encoded therein. As a result necessary time sync information such as program clock reference information cannot be guaranteed to be delivered within the time interval thresholds mandated by certain industry broadcast standards, such as MPEG-2 and digital video broadcast (DVB). Transmission of reference signals, such as PCR information, may be assured by inserting detection means to detect the time interval between occurrences of the reference signal. If the interval between occurrences of the reference signal exceeds a predetermined time interval threshold, the detection means will instruct a memory device to provide a reference signal, which is then imprinted with reference signal information and inserted into the stream of information being output by the multiplexer. Alternatively, the multiplexer may simply provide an output signal at a preset predetermined time intervals, regardless of whether or not a reference signal is being provided by the input stream. In this embodiment, the output signal may occur substantially more frequently than is required by the time interval threshold of the relevant broadcast standard.1015

Title: A process for making poly(urethane-urea)/addition polymer composite particles
Inventor: WILLIAMS NEAL ST JOHN
IPC: C08G18/66
Filed: 2001-06-15
Abstract: A process for making poly(urethane-urea)/addition polymer composite particles which avoids the need to use a highly viscous solution of a prepolymer for the poly(urethane-urea). The process comprises dissolving diol and diisocyanate in addition polymerisable monomers and allowing them to co-react but for only long enough to form a precursor for the prepolymer which is of a lower molecular weight than the prepolymer so that the precursor forms a solution of much lower viscosity. This lower viscosity solution is then dispersed in water to give droplets in which the co-reaction continues and completes the formation of the prepolymer whilst water diffuses into the droplets and causes chain extension to create the poly(urethane-urea) particles. The addition polymerisable monomers in the dispersed droplets spontaneously diffuse into the poly(urethane-urea) particles where they are subjected to a conventional free radical addition polymerisation process whereupon composite the poly(urethane-urea)/addition polymer particles are formed. The composite particles can be obtained as stable aqueous dispersions optionally containing less than 3wt% organic solvent and over 40wt% of the composite particles.
