Title: Process for gradient refractive index optical objects
Inventor: LA FLEUR EDWARD EWART
IPC: G02B3/00
Filed: 1997-09-29
Abstract: An improved process, preferably continuous, for the manufacture of gradient refractive index optical objects, wherein a core polymer, which itself may be prepared by a continuous and incorporated process, is passed through a hollow porous surrounding, generally cylindrical so as to obtain and maintain a rounded fiber, through which is fed a second monomer whose polymer has a lower refractive index than the core polymer, so as to swell the core polymer. The swollen polymer with a gradient of swelling by the second monomer from surface to core, is then led to a polymerization unit to complete the polymerization before equilibration of the second monomer throughout the core polymer occurs. The resulting polymers are useful in the preparation of optical fibers and light pipes.
Patent CA-2217927-A1 (CA)
Inventor: MCCURDY RONALD EDGAR
IPC: F16D41/26
Filed: 1997-11-18
Abstract: The invention relates to an adjustable mechanical means of changing the connective relationship between the sprockets of a chain-driven device (tricycle, bicycle, or other multiwheeled conveyance). By a simple adjustment of screws, the relationship may be freewheel, as found in multispeed bicycles. By the same token, a further adjustment may be readily effected so as to render a solid connection between the pedal operation and the drive portion.  As well, an infinite gradation between freewheeling and solid drive can be effected. The availability of having solid, freewheel, and an infinite linkage variation between these two extremes is provided by adjusting screws.  In the preferred embodiment, the adjusting screws are made of a material softer than the outer freewheel member to which they may attain a frictional connection. Use of the outer portion of the freewheel member adjacent to the chain allows stronger coupling of the freewheel without requiring undue tightening of the screws.  The screws themselves are threaded into a plate welded or otherwise fixed to the central portion of the freewheel which in turn is securely attached to either an axle, crank shaft, or the drive wheel itself.

Title: User invocation of services in public switched telephone network via parallel data networks
Inventor: STERN EDITH HELEN
IPC: H04M7/12
Filed: 1997-11-27
Abstract: This invention allows customers and other users of the Public Switched TelephoneNetwork (PSTN) to enable, disable or modify special services provided by the network. The PSTN is defined here as all equipment world wide (land-based, radio or other) enabling ordinary telephone users to connect to other telephone users, but excludes private telephone networks such as "tie line" systems maintained or leased by private enterprises.  Presently contemplated actions can be taken independent of the state of the customer's telephone line (e.g. on-hook or off-hook), and usually involve use of equipment other than telephones and communication networks other than the PSTN (e.g. computers operating through the Internet and pagers operating through pager networks).  The special services include existing services (call waiting, call blocking, call forwarding, etc.) and new ones (e.g. transferring an active call from a desk phone to a mobile cellular one without interrupting the call).  Security firewalls, between the public and telephony application intelligence (TAI) systems that administer customer services within the PSTN, ensure that actions by unauthorized individuals do not interfere with or adversely affect telephone system operations.  Authorized customers taking presently contemplated actions will not be able to adversely affect telephone system operations.  The present system will work on information maintained at any level of an intelligent network hierarchy within the PSTN, including service nodes through which customer services are traditionally provided.
