Abstract: Un procédé permet de produire un stéroïde époxy de la formule (1.0) où R?1¿ est choisi parmi H, -OH, ou C1, et R?2¿ est choisi entre hydrogène ou alkyle inférieur. Ce procédé consiste à faire réagir un triène de formule (2.0) avec un agent de bromination ou de chloration dans du DMF contenant une quantité catalytique de 70 % de HCl¿4?, à une température allant de 0 à 40 ·C environ, pour produire le bromoformate de la formule (3.0) ou le chloroformate de la formule (3.0A) dans lesqulles si R?1¿ représente H, R?3¿ représente également H; si R?1¿ représente -OH, R?3¿ représente un groupe -OH judicieusement protégé; et si R?1¿ représente C1, R?3¿ représente également C1. On fait alors réagir ce bromoformate ou chloroformate, à une température allant d'environ -20 ·C à +10 ·C, avec une base forte dans un mélange de solvants organiques comprenant: (a) THF ou CH¿2?C1¿2?, et (b) un C¿1-6? alcanol ou acétonitrile, afin de produire le stéroïde époxy de la formule (1.0).

Title: Communication system architecture, exchange and method of operation
Inventor: LEWIS ANDREW PAUL
IPC: H04M11/06
Filed: 1998-08-18
Abstract: An exchange (12) has a cross-point switch that is arranged to couple data transmission between subscriber terminals (16, 18), each having a dedicated modem (34), and at least one assignable modem (148) located in the exchange (12). The exchange (12) comprises fewer assignable modems than a combined number of dedicated modems within the subscriber terminals (16, 18) and, since the cross-point switch (106) is responsive to the data transmission sent via the modems of the subscriber terminals, the cross-point switch (106) thereby acts to concentrate a ratio of dedicated modems to assignable modems.

Patent CA-2250546-A1 (CA)
Inventor: ROOYAKKERS GERARDUS HENRICUS F
IPC: B65H75/14
Filed: 1998-10-27
Abstract: In conventional reels for storing electrical cable it is known that in order to achieve the required strength more material is required resulting in an increased mass of the reel. This invention, preferably made of mild steel, is lightweight because of the arrangement of the spokes, which permit indirect tangential loading of the hubs, and enables less material to be used in its construction without sacrificing strength. The arrangement of the spokes also allows the load in the spokes to be dissipated to a certain degree by flexing of the spokes during handling. The lightness of the reel facilitates handling thereof by a single user. This invention will provide a cost effective, environmentally friendly alternative to conventional reels currently available.    The reel of the invention may be used in particular but not exclusively for storing electrical cable to be transported to various destinations. Once transported to such a destination the cable is unwound from the reel to permit laying or installation thereof. The reel is then left at that destination where it may be dismantled, re-used or recycled in any other field of application.

Patent CA-2266990-A1 (CA)
Inventor: RAMASWAMY SRIDHAR
IPC: G06F17/30
Filed: 1999-03-25
Abstract: An approximate query answering system that provides fast, highly-accurate approximate answers to database queries. The system provides these approximate answers using small, pre-computed synopsis data structures (samples, counts, etc.) from the underlying database and accuracy guarantees without any a priori assumptions on either the data distribution, the order in which the base data is loaded, or the layout of the data on the disks. The system also provides fast approximate ansers for queries with selects, aggregates, group bys and/or joins (especially, the multi-way foreign key joins that are popular in Online Analytical Processing (OLAP)). The system uses several new techniques for improving the accuracy of approximate query answers for this class of queries, including, (1) join sampling to significantly improve the approximation quality and (2) biased sampling to overcome the problem of group size disparities in group by operations. Moreover, the system uses efficient algorithms for incremental maintenance of join samples, biased samples, and all other synopses used in the current system. The system remains effective even in the presence of data distribution changes.

Abstract: Dans le domaine de l'acériculture on utilise un chalumeau afin de récolter l a sève de l'érable. Dans la présente invention, nous avons créer un adapteur souple, conique qui doit être glissé à l'extrémité du chalumeau qui sera introduit dans l'entaille. Ceci aura comme effet de diminuer le contact direct du chalumeau avec la paroi intérieure de l'entaille, donc augmentera la superficie interne de l'entaille procurant la  sève, et du même coup, permettre d'augmenter le volume de sève récolté par entaille. Il peu aussi servir d'adapteur dans le cas ou l'on voudrait soit grossir le diamètre d'un  chalumeau soit utiliser un même chalumeau tout en ravivant les entailles.
