Patent CA-2387913-A1 (CA)
Inventor: BAMFORD ROGER
IPC: H04L1/16
Filed: 2000-10-18
Abstract: A method and mechanism is described for reliably transmitting messages over an unreliable transport mechanism. A (180) sender transmits a first message over an unreliable transport mechanism (150) to a receiver (190), and a second message that identifies the first is transported over a reliable transport mechanism (160) to the receiver. When the receiver (190) receives the second message, the receiver (190) determines whether it has received the first message. If not, the receiver (190) requests retransmission of the first message.

Title: Process for selectively producing c3 olefins in a fluid catalytic cracking process
Inventor: STUNTZ GORDON F
IPC: C10G11/05
Filed: 2001-05-19
Abstract: A process for producing polymers from olefins selectively produced from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha stream is introduced into a process unit comprised of a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an avera ge pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures ranging from about 500.degree . to 650 .degree.C and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles  are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the strippi ng zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone. Overhead products from the reaction zone are passed to a fractionation zone where a stream of C3 produc ts is recovered and a stream rich in C4 and/or C5 olefins is recycled to the stripping zone. The olefins can be further processed and polymerized to form a variety of polymer materials.

Abstract: L'invention porte sur un procédé de sélection et de traitement d'un plan de retenue salariale comme option de paiement d'articles achetés par voie électronique. Un employeur autorise des vendeurs sélectionnés, évoluant dans le commerce électronique, à accepter une retenue salariale comme option de paiement pour ses employés. L'employeur et le vendeur établissent des lignes de guidage pour utiliser l'option de retenue salariale dans une opération de commerce électronique et le vendeur mémorise dans une base de données de son ordinateur les lignes de guidage et des informations d'identification destinées à l'employeur et à ses employés. Par conséquent, lorsqu'un employé sélectionne des articles sur le site web du vendeur, il peut sélectionner la retenue salariale comme option de paiement. Le vendeur place les sélections de l'employé et l'option de paiement dans un fichier et les envoie à l'employeur. L'employeur peut approuver ou refuser la sélection de l'employé et le vendeur traite la commande conformément aux instructions de l'employeur. Le vendeur informe alors l'employé de l'état de sa commande. Ce procédé offre donc aux employés autorisés l'option d'utiliser la retenue salariale dans une opération de commerce électronique.
