Inventor: BOURGON PIERRE
IPC: F23R3/40
Filed: 2000-02-22
Abstract: The JET ENGINE CATALYTIC CONVERTER is a catalytic converter built into the engine. This invention uses platinum(Pt), the primary catalyst used in automobile catalytic converters.

Patent CA-2312235-A1 (CA)
Title: System and method of targeted marketing
Inventor: JONES CHARLES L
IPC: G06Q30/02
Filed: 1998-10-26
Abstract: A system and method of targeted marketing to consumers, including businesses and associates, based upon the financial characteristics of the consumer, type offer being made and the channel of communication for delivery of the offer. The consumer is characterized based upon financial, behavioral, and socioeconomic factors. The offer is characterized based upon the consumer and the potential for the consumer accepting the offer. The channel of communication for delivery of the offer is also characterized and combined with the consumer and consumer-offer characteristics to arrive at a net present value of the offer to be made. If the net present value is sufficient the offer is processed and presented to the consumer. If the net present value is not sufficient, the offer is revised to present a better value to the consumer (or discarded if the required offer value can not be created) thereby enhancing the chances that the consumer will accept the offer in question. In this way the system and method of the target marketing creates value in both releasing, and not releasing specific offers.

Patent CA-2322447-A1 (CA)
Title: Process for treating gas flows of polyolefin manufacturing
Inventor: NYMAN TIMO
IPC: C08F6/10
Filed: 1999-03-04
Abstract: The invention relates to a process for the treatment of a gas stream obtained from the production of polyolefins and containing unreacted compounds. According to the process, uncondensed compounds are removed from the gas stream and, when so desired, these compounds are directed to further treatment. According to the invention, the uncondensed compounds are separated from the gas stream by membrane separation. Thus the separation of gases is facilitated, since by coupling the membrane system in conjunction with distillation columns the distillation can be carried out at a substantially higher top temperature. By using the membrane system it is possible effectively to remove the lightest gases, which would otherwise accumulate in the process.

Abstract: Les glycoprotéines associées à la grossesse (PAG) sont structurellement apparentées aux pepsines, que l'on croyait limitées aux ongulés et qui s'expriment en particulier dans la couche extérieure des cellules épithéliales (chorion/trophectoderme) du placenta. On estime que par un clonage des gènes exprimés provenant de banques génomiques placentaires d'ovins et de bovins, le bétail, les ovins, et très certainement tous les Artiodactyles ruminants, peuvent posséder au moins 100 gènes PAG, dont la plupart sont exprimés dans le placenta. Ces gènes PAG divergent largement au niveau de leurs séquences et présentent des régions d'hypervariabilité, généralement limitées à des boucles exposées en surface. Certains gènes PAG sont le produit de cellules binucléaires invasives, qui sont exprimées fortement dans une grossesse précoce au moment de l'invasion trophoblastique, et faiblement, voire pas du tout, dans une gestation tardive, ces gènes PAG permettant par ailleurs un diagnostic précoce de la grossesse. Dans un mode de réalisation préféré, cette invention concerne des essais immunologiques permettant de détecter ces gènes PAG.

Abstract: Delivery components allow data read, write or operation requests and data responses to pass between a client software application and access components.  Each delivery component is developed specifically for each client application.  Furthermore, data views (that is, sets of mapping and stored procedures) receive data read, write or operation requests and construct responses, and allow data responses to pass to system domain server components from a target database that is not compatible with the client application. Each set of data views is developed specifically for each target database, and provides virtual compatibility for each target database with each client application. The delivery components and the data views together allow the client application to access the incompatible database through the access components and system domain server components.
