Title: Process for the recovery of metallic iron from slags and other residues
Inventor: CRISTOVICI MARIUS A
IPC: C22B7/04
Filed: 1995-10-31
Abstract: A process for the recovery of at least a major proportion of the useful metallic iron values in small sized ferrous slags and drosses  in which the slags and drosses are subjected to at least one grinding step in a wet grinding mill. Depending on the size of the slag and dross particles, either a peripheral end discharge rod mill or an axial discharge ball mill is used.  In a preferred configuration, two wet grinding stages are used, comprising a peripheral end discharge rod mill followed by a ball mill.  Products with different metallic iron contents are recovered by interposing screens with suitably sized openings between and after the grinding mills.   This process makes it possible to recover at least about 80% of the metallic iron in the feed material.

Patent CA-2174344-A1 (CA)
Inventor: ZEHAVI EPHRAIM
IPC: H04J13/00
Filed: 1994-11-01
Abstract: Cette invention se rapporte à un système et à un procédé améliorés, qui servent à communiquer des informations à des vitesses de données variables le long de canaux de communications de type en phase (I) et de type à quadrature de phase (Q) dans un système de communications à spectre étalé AMDC (accès multiple par différence de code). Dans une réalisation exemplaire d'un tel système, un signal d'informations d'entrée est transmis le long d'un canal de communications soit de type I soit de type Q, grâce à l'utilisation d'un signal de communications à spectre étalé en séquence directe. Ce signal d'informations est d'abord divisé en un premier sous-signal et en un second sous-signal, lesquels sont respectivement fournis à des premier et second réseaux de codage d'ensembles secondaires. Le premier réseau de codage d'ensembles secondaires combine le premier sous-signal avec un premier code d'ensemble secondaire, tandis que le second réseau de codage d'ensembles secondaires combine le second sous-signal avec un second code d'ensemble secondaire, orthogonal par rapport au premier code d'ensemble secondaire. Ainsi, les premier et second réseaux de codage d'ensembles secondaires fonctionnent de façon à produire des premier et second signaux à codage d'ensembles secondaires, respectivement. Un signal à codage d'ensemble secondaire composite, formé à partir des premier et second signaux à codage d'ensembles secondaires, est ensuite modulé par un signal de fonction orthogonale, pour produire un premier signal modulé. Un signal de bruit pseudo-aléatoire en phase (PN¿I?) et un signal de bruit pseudo-aléatoire à quadrature de phase (PN¿Q?), ayant des codes PN prédéterminés, sont utilisés pour étaler le premier signal modulé, en vue de sa transmission à destination d'un récepteur le long du canal de communications soit de type I soit de type Q, respectivement. Ledit récepteur fonctionne de façon à produire une estimation du signal d'informations d'entrée, sur la base du signal porteur modulé reçu par l'intermédiaire du canal de communications soit de type I soit de type Q.
