Patent CA-2248105-A1 (CA)
Inventor: MCKEE PAUL FRANCIS
IPC: H04M15/00
Filed: 1997-04-01
Abstract: Dans un système de taxation de télécommunications cellulaires, des prix en temps réel pour de nouvelles communications sont proposés au client. Ces prix en temps réel tiennent compte à la fois des structures de trafic actuelles et passées, ainsi que de la probabilité que le client se déplacera depuis sa cellule normale vers l'intérieur d'une cellule avoisinante. Les cellules du réseau sont contrôlées en grappes. Si un client est situé dans une cellule particulière, le prix proposé à ce client tiendra compte de la probabilité de transfert vers une cellule avoisinante pendant la communication et, éventuellement, de la probabilité de trafic d'arrivée depuis des cellules avoisinantes pendant la communication. Afin de faciliter cette tarification prédictive, le système mémorise et, éventuellement, met à jour les données historiques.

Patent CA-2299263-A1 (CA)
Inventor: GREENWALT RICHARD B
IPC: C22B5/10
Filed: 1998-04-06
Abstract: A method of upgrading relatively rich, fine-grained earthy hematite iron ores is provided. The iron ore, after suitable preparation, is reduced using a solid state reduction technique. As a result of the reduction process, the iron grains undergo size enhancement while the nonmetallic oxides are unreduced and remain as refractory oxide gangue. After completion of the reduction process, the enlarged malleable metallic iron grains are crushed in such a way as to cause the iron grains to fuse together, forming large, flat iron flakes. In order to achieve maximum flake size, the crushing system applies a relatively gradual pressing force rather than a rapid, impact type of force. The flakes are generally greater than 0.1 millimeters in size, and typically in the range of 0.3 to 0.5 millimeters. As the large flakes are formed, the iron grains are liberated from the refractory oxide grains resulting in an increase in density from about 4 to 5 grams per cubic centimeter to about 6 to 7 grams per cubic centimeter. The crushing system causes non-iron oxide bonds to be broken, resulting in the formation of residual refractory particles generally with a grain size of less than 0.05 millimeters, and typically less than 0.01 millimeters. The shape, size, density, and ferromagnetic differences between the iron flakes and the nonmetallic oxides are used to separate the iron from the nonmetallics. A variety of different separation techniques may be used, including screens, jigs, spirals, elutriation, cyclones, magnetic, and gravity separation. Although other processes may be used, preferably the final concentration and cleaning is accomplished using a low-intensity magnetic separator. The combination of solid state reduction, mechanical working, and physical/electromagnetic separation enable consistent production of super concentrates of material with metallic iron contents exceeding 92 % with less than 4 % oxide gangue and an iron recovery of greater than 95 %.
