Patent CA-2391856-A1 (CA)
Inventor: HEROLD ROBERT D
IPC: C08G18/82
Filed: 2000-11-18
Abstract: L'invention concerne un nouveau procédé de préparation d'un polymérisat, qui consiste à polymériser une composition à deux composants. Un premier composant contient au moins un réactif polycyanate ayant au moins deux groupes fonctionnels choisis parmi isocyanate, isothiocyanate et des combinaisons de ceux-ci, le réactif de polycyanate étant le produit de la réaction d'un monomère polythiol ayant au moins deux groupes thiol; et un monomère polycyanate ayant au moins deux groupes fonctionnels choisis parmi isocyanate, isothiocyanate et des combinaisons de ceux-ci. Un second composant contient au moins un réactif polyamine ayant au moins deux groupes fonctionnels choisis parmi amine primaire, amine secondaire et des combinaisons de ceux-ci. Le rapport équivalent molaire des groupes (NCO + NCS) du premier composant aux groupes (-NH¿2? + -NH-) du second composant est de 0,5 à 100. L'invention concerne également des polymérisats préparés selon ce procédé. Elle concerne en outre des articles photochromiques qui peuvent être préparés à partir desdits polymérisats.
Patent CA-2392664-A1 (CA)
Title: A broadcast/multicast system and protocol for circuit-switched networks
Inventor: WEINMAN JOSEPH BERNARD JR
IPC: H04M3/42
Filed: 2002-07-05
Abstract: A system and method directed to providing a broadcast/multicast in a circuit-- switched network. An exemplary method includes receiving at a first switch a call directed to a called number; determining whether the first switch has an active connection to the called number; if the first switch has an active connection to the called number, merging the call with the active connection; and if the first switch does not have an active connection to the called number, routing the call to a next switch. The process is repeated as necessary until a next switch with an active connection is identified and/or the switch serving the called number is reached. The present invention conserves network resources and increases network efficiency, in part, by not carrying a call any further than is necessary for the caller to participate in a broadcast/multicast.

Title: Inhalation therapy decongestant with foraminous carrier
Inventor: GOON DAVID J W
IPC: A61K9/00
Filed: 2000-05-12
Abstract: A vaporizable decongestant is supported and stabilized on a flexible foraminous carrier composed typically of open-cell plastic foam, cloth or other fibrous material such as nonwoven fabric. The term "foraminous" herein is intended to refer to a substance or medium containing minute openings or perforated by many minute apertures. The decongestant is placed on the surfaces within the interstices and minute apertures or on fibers from which the foraminous carrier is formed. Vaporization of the inhalable decongestant is facilitated by providing the potential for greatly increasing its exposed surface area. Distributing the decongestant composition over the large, expanded surface within the foraminous carrier is beneficial in enhancing both the volatilization and evaporation of the decongestant agent. It also prolongs the useful life of the product. Once vaporized, the aromatic decongestant is available for natural inhalation through the nose or mouth to help relieve one or more of the symptoms of cough, colds, nasal or chest congestion and related symptoms. The foraminous carrier is preferably provided in the form of a patch or sheet that is bonded to the skin to serve as a supporting base for the active decongestant agent. The patch defining the carrier is typically adhesively bonded to the upper part of the body, <i>e.g.</i> on the face, neck or chest, in a location where the decongestant is liberated into the air and can be inhaled through the mouth or nose.
