Title: Production d'olefines vinylideniques
Inventor: LIN KAUNG-FAR
IPC: C07C2/30
Filed: 1997-02-04
Abstract: Une oléfine vinylidénique peut être obtenue sous un rendement et une sélectivité élevés et avec des temps de réaction inférieurs aux temps jugés critiques jusqu'à présent. Le procédé consiste à dimériser une oléfine vinylique à l'aide, au moins, d'un composé trialkyle aluminium en tant que composant de catalyse chargé dans la cuve de réaction. Ces matériaux sont chargés dans le réacteur dans des conditions telles que celui-ci contienne de 0,001 à 0,5 mole de trialkyle aluminium par mole d'oléfine vinylique initiale. La réaction s'effectue sous une température comprise entre 100 et 200 ·C pendant un laps de temps suffisant pour convertir de 10 à 99 % en poids de l'oléfine vinylique initiale en un produit différent constitué, au moins à 80 % en poids, par le dimère vinylidénique recherché. Dans la réalisation de l'opération, le mélange de réactions liquide est au contact direct d'une surface d'alliage métallique contenant du nickel pendant au moins une heure sous une température supérieure à environ 50 ·C, et au moins un hydrocarbure acétylénique est ajouté au mélange avant ledit contact dans une proportion au moins suffisante pour neutraliser l'isomérisation à doubles liaisons dans le mélange de réaction, mais non suffisante pour neutraliser la formation dimère vinylidénique. L'hydrocarbure acétylénique permet également d'éviter les effets dévastateurs que les impuretés de nickel dans la charge ou dans les résidus à l'intérieur du réacteur peuvent avoir sur la sélectivité du dimère.

Title: Method and device for variable, current rate signalling of in-based value-added services
Inventor: LAUTENSCHLAGER WOLFGANG
IPC: H04Q3/00
Filed: 1998-10-14
Abstract: A method for the variable, service-specific rate signalling of value-added services by a called destination subscriber (B) who is offering IN (Intelligent Network)-based services in a telecommunications network (TK), during an actual connection to a calling A-subscriber who is requesting an offered IN-service, ischaracterized in that via his service provider installation (10), the destination subscriber sends a rate signal, which corresponds to the actual rate requested by the destination subscriber, to a central control logic in the TK network, that the service control point (SCP) by means of a service logic checks the entitlement of the destination subscriber to impose the rate he has requested, and that if it is compatible, the service control point routes a corresponding fee charging information via a service switching point to the requesting A-subscriber, and to a customer data acquisition (KDE) connected to the TK network, whereby the customer data acquisition calculates the fees to be paid by the calling A-subscriber. This method makes it possible for the called destination subscriber to expand value-added services, which are IN-based anyway, to variable rate charging without great additional effort; however the entitlement to the rate charging isalways checked at a neutral place of the TK network.

Patent CA-2267475-A1 (CA)
Title: Atm adaptation layer traffic scheduling
Inventor: DUBUC KEN
IPC: H04L47/43
Filed: 1999-03-30
Abstract: The ATM transmitting apparatus for transmitting messages, such as frame relay packets, associated with a plurality of connections comprises ATM layer transmission equipment for receiving multiple messages, segmenting each received message into a plurality of smaller data units, such as 48 byte AAL SAR protocol data units, and multiplexing such data units into a single stream for transport over a physical interface. A scheduler receives messages from each of the connections and transfers the messages to the transmission equipment. The scheduler can dynamically set a transmission rate for any connection, and allocates each connection whose message is transferred to the transmission equipment a substantially maximal amount of bandwidth at any given time during the transmission of the message, to thereby minimize interleaving of data units from the various connections and reduce the average latency (per unit of message) in transmitting the messages across a network. The apparatus also reduces latency in variable bit rate connections by scheduling the transfer of messages to the transmission equipment in an order corresponding to the level of a leaky bucket associated with each connection, and by setting the transmission rate for the connection up to its burst rate such that the connection will stay in conformance with its traffic contact.
