Patent CA-2199512-A1 (CA)
Title: An Intelligent Telecommunications Network
Inventor: GILLMAN RICHARD JAMES
IPC: H04L29/06
Filed: 1995-09-14
Abstract: An intelligent network comprises switching units (54, 56) interconnected to provide connections between originating users (50) and terminating users (52).  The intelligent network includes a set of SCPs (60 to 70) which can be accessed by the switching units through a signalling network (58). The SCPs contain individual service profiles which define the individual services provided to users of the network as originating users and individual service profiles which define the individual services provided to the users as terminating users. During call set-up, a service control program which acts as agent for the originating user is generated from the service profile for the originating user as an originating user and a service control program which acts as agent for the terminating user is generated from the service profile for the terminating user as a terminating user. The two service control programs then enter into a dialogue with each other in order to generate call control instructions.

Abstract: ABSTRACT OF THE DISCLOSURE   A method for the separation and recovery of fluorochemicals from a gas stream containing a diluent gas and fluorochemicals by contact of the gas stream with amembrane, comprising the steps of: compressing a gas stream containing a diluent gas and fluorochemicals to an elevated pressure; heating the gas stream containing adiluent gas and fluorochemicals to an elevated temperature sufficient to increase the flux of the permeate stream and to increase the selectivity of the membrane for the permeation of the diluent gas relative to the permeation of the fluorochemicals;contacting the gas stream with a membrane which is selectively more permeable to the diluent gas than the fluorochemicals to result in a permeate stream rich in the diluent gas and a retentate rich in fluorochemicals; contacting the gas stream with one or more additional membranes which are selectively more permeable to the diluent gas than the fluorochemicals to result in a second permeate stream rich in the diluent gas and a second retentate rich in fluorochemicals; and recycling the second permeate stream to be compressed with the gas stream containing diluent gas and fluorochemicals to an elevated pressure. Preferably, the second retentate rich in fluorochemicals is further purified by adsorption or low temperature rectification to provide a fluorochemical-rich product stream and a diluent-rich vent stream.
