Patent CA-2212785-A1 (CA)
Title: Liquid-filled separator for use in a fluidized-bed polymerization process
Inventor: POWER MICHAEL BERNARD
IPC: C08F10/00
Filed: 1997-08-12
Abstract: The invention relates to continuous gas fluidised bed polymerisation of olefins, especially ethylene, propylene, or mixtures of these with other alpha olefins, wherein the monomer-containing recycle gas employed to fluidise the bed is passed through a separator. The separator is charged with and maintained at least partially filled with liquid. Entrained catalyst and/or polymer particles are separated from the recycle gas in the separator and these separated particles are maintained in a suspended state in the liquid in the separator. The recycle stream can be cooled to condense out at least some liquid hydrocarbon; the condensed liquid, which can be a monomer or an inert liquid, is separated from the recycle gas in the separator and is fed directly to the bed to produce cooling by latent heat of evaporation. The process reduces fouling of the separator.

Abstract: L'invention concerne des procédés pour identifier un gène au niveau d'un locus chromosomique aléatoire dans le génome d'une cellule mammifère. L'un de ces procédés consiste à inactiver une copie du gène par intégration d'un produit de recombinaison d'ADN (produit de recombinaison par élimination) dans cette copie du gène. Ce produit de recombinaison par élimination comprend une séquence de régions marqueurs de sélection positive et, dans une direction 5' partant de cette séquence, une séquence de régions d'initiation de transcription en réaction à un facteur de transactivation, ladite région d'initiation de transcription étant orientée, en vue d'une transcription d'ARN antisens, dans la direction opposée à la séquence de régions marqueurs de sélection. La deuxième copie du gène est inactivée par transformation des cellules avec un deuxième produit de recombinaison d'ADN (produit de recombinaison par transactivation) contenant une séquence génique destinée au facteur de transactivation qui initie la transcription d'ARN antisens s'étendant du produit de recombinaison par élimination jusque dans le locus chromosomique adjacent au produit de recombinaison par élimination, au niveau de son extrémité 5'. L'inactivation des deux copies de gène peut entraîner une modification du phénotype cellulaire pouvant être distingué du phénotype de type sauvage. Eventuellement, ce dernier peut être récupéré par introduction d'un troisième produit de recombinaison en mesure d'inhiber la transcription d'ARN antisens. L'invention décrit par ailleurs un gène associé à la prédisposition tumorale des cellules mammifères, le tsg 101.
