Title: Procede de production de fonte brute liquide ou de precurseurs d'acier liquides
Inventor: WALLNER FELIX
IPC: C21B13/06
Filed: 1997-06-26
Abstract: L'invention concerne un procédé de production de fonte brute (43) liquide ou de précurseurs d'acier liquides, à base de charges comprenant du minerai de fer (5) et des fondants, et présentant au moins en partie des fines. Selon ce procédé, le minerai de fer fait l'objet d'une réduction directe en lit fluidisé dans au moins deux étages de réduction, pour former du fer spongieux qui est mis en fusion dans une zone de gazéification par fusion (39) sous apport de substances porteuses de carbone et de gaz contenant l'oxygène. Un gaz de réduction contenant du CO et du H¿2? est produit et est introduit dans des zones de réduction des étages de réduction (1, 2) où il est converti et est extrait sous forme de gaz de gueulard, avant d'être éventuellement acheminé jusqu'à un consommateur. Afin de parvenir à une réduction homogène du minerai de fer avec une utilisation optimale du gaz de réduction, dans un premier étage de réduction (1), le minerai de fer (5) est fractionné à l'aide de gaz de réduction en au moins deux fractions à répartition différenciée de la grosseur des grains; chaque fraction est réduite à l'aide du gaz de réduction dans un lit fluidisé (6, 15) qui lui est propre; le gaz de réduction maintient un premier lit fluidisé (6) contenant la fraction à gros grains et en sépare la fraction à grains fins, du gaz de réduction étant ensuite introduit directement dans le lit fluidisé suivant (15); le minerai de fer (5) réduit est extrait aussi bien du premier lit fluidisé que du suivant (6, 15); et la fraction à grains fins et la fraction à gros grains réduites dans le premier étage de réduction (1) font l'objet d'un autre réduction dans au moins un autre étage de réduction (2) fonctionnant de manière similaire au premier étage de réduction (1). La fraction à grain fins issue du dernier étage de réduction (2) est acheminée dans la zone de gazéification par fusion (39) de manière à produire une agglomération par adjonction d'oxygène et la fraction à gros grains est acheminée directement dans la zone de gazéification par fusion (39), par gravitation.

Title: Alkaline hair conditioning compositions containing cationic guar
Inventor: VARCO JOSEPH J
IPC: A61Q5/12
Filed: 1999-03-01
Abstract: The invention provides compositions for relaxing and conditioning keratinous fibers, particularly human hair. The compositions of the present invention have a high pH, i.e., a pH greater than 10, preferably, in the range of about 11 to about 14, more preferably about 12 to about 13.5; and include as a conditioning additive a cationic guar. Surprisingly, the cationic guar maintains stability, viscosity and activity over time in the highly alkaline pH of the inventive hair relaxer and conditioning compositions of the present invention. The relaxer compositions of the present invention afford beneficial effects to the user, such as softness and ease of wet combing, and cause less damage to hair following application and use. In addition, the conditioning relaxer compositions of the present invention remain on the hair and provide lasting conditioning and relaxing effects after one or more shampoos.

Title: Method and apparatus for detecting bad data packets received by a mobile telephone using decoded speech parameters
Inventor: JACOBS PAUL E
IPC: G10L19/00
Filed: 1997-09-24
Abstract: The mobile telephone detects bad data packets by decoding speech parameters represented by the packets and comparing those speech parameters against acceptable ranges of speech parameters. If the speech parameters do not lie within the acceptable ranges, the packets are discarded. This speech parameter-based detection of bad data packets is particularly useful in mobile telephones receiving variable rate data packets wherein an error in determining the rate of a packet results in the entire packet being decoded at an incorrect rate, thereby likely causing an annoying audible artifact in the decoded speech signal. Such rate detection errors can occur eventhough a CRC  or other conventional error detection check fails to detect the bad packet. In an exemplary implementation, receiver (132) of mobile telephone (128) receives signals encoded with TIA/EIA/IS-95-A standards. Variable rate decoder (140) determines linear speech parameter frequencies and codebook gain parameters using linear predictive coding techniques. The parameters are tested against acceptable ranges to detect bad data packets by speech parameter examining unit (144).

Abstract: L'invention concerne (+/-)-1-azabicyclo[2.2.1]heptan-3-one racémique, pouvant être efficacement fractionné en ses isomères (1S, 4R)-1-azabicyclo[2.2.1]heptan-3-one et (1R, 4S)-1-azabicyclo[2.2.1]heptan-3-one par formation de ses sels d'hémitartrate de di-p-toluoyle par combinaison avec de l'acide di-p-toluoyl-L-tartrique et de l'acide di-p-toluoyl-D-tartrique, respectivement. Une cristallisation sélective à l'aide d'un des acides di-p-toluoyltartriques, en quantité inférieure à la quantité stoechiométrique, dans un mélange de solvants appropriés, permet d'isoler l'isomère souhaité comme son hémitartrate de di-p-toluoyle respectif avec une pureté isométrique élevée. Une fois stockés, les hémitartrates isolés restent stables. On peut les employer comme tels pour préparer des produits pharmaceutiques et d'autres composés biologiquement actifs, ou pour constituer la base libre de l'isomère 1-azabicyclo[2.2.1]heptan-3-one respectif.
