Patent CA-2454980-A1 (CA)
Title: Multiplexer discovery and parameter exchange
Inventor: SCHOLTE ALEXANDER MARTIN
IPC: H04L12/56
Filed: 2004-01-09
Abstract: The present invention is directed to the discovery of network devices capable of handling multiplexed packet data flows. According to the present invention, multiplexing routers included in a path along which communication resources are reserved insert an object into the RSVP RESV message, to provide operating parameters to an originating multiplexing router. Using the operating parameters provided by multiplexing routers along the path, the originating multiplexing router can identify a multiplexing router proximate to a receiving communication device or devices. The originating multiplexing router can then create super packets addressed to the receiving multiplexing router proximate to the receiving communication that contains multiple data packets. The router to which the super packet is addressed can then deaggregate the super packet, and deliver the data packets to the receiving communication device or devices.

Filed: 2002-12-26
Abstract: This invention relates to a process for preparing high-purity aromatic oligomers by effectively separating an organic layer containing aromatic oligomers or the reaction products of a polycyclic aromatic compound with formaldehyde from an aqueous layer containing an acid catalyst in a simplified manner, hitherto regarded difficult to accomplish, and obtaining high-purity aromatic oligomers from the organic layer containing a reduced amount of impurities. In separating the aqueous layer containing the acid catalyst and the organic layer containing the oligomers from the reaction mixture formed by the condensation of a polycyclic aromatic compound and formaldehyde, the emulsion phase is broken by adding a nonionic or cationic surfactant in an effective amount and an alkali in an amount sufficient to neutralize 1-70% of the acid in the acid catalyst, the organic and aqueous layers are separated and the aromatic oligomers are recovered from the organic layer.

Abstract: L'invention concerne un récipient comportant une buse et un corps qui en dépendent. Ledit corps, de préférence tubulaire, définit un intérieur qui retient un produit à distribuer. Un capuchon, en prise avec la buse, empêche la libération accidentelle du produit. Afin de distribuer le produit, on enlève le capuchon et on applique une pression sur le corps et la buse libère le produit. La buse libère le produit sans que le produit restant soit exposé au milieu extérieur, la stérilité de l'intérieur du corps étant ainsi maintenue et la durée de vie du produit accrue. La buse comporte un corps intérieur, couplé au corps tubulaire, entouré d'une enveloppe externe souple. Un joint, entre le corps interne et l'enveloppe externe souple, forme une valve de libération à sens unique, une partie du joint demeurant fermée pendant la distribution du produit.
