Title: Procede de valorisation d'un minerai de fer au moyen de plusieurs separateurs magnetiques
Inventor: LEHTINEN LARRY J
IPC: B02C23/08
Filed: 1998-11-05
Granted: 2007-07-10
Abstract: La présente invention concerne la valorisation d'un minerai de fer, consistant à réduire sa teneur en matériaux non ferreux et donc à accroître la teneur en fer dudit minerai. En particulier, l'invention concerne un procédé utilisant des champs magnétiques (20, 50, 140) pour séparer un flux d'alimentation en fractions magnétiques (30, 60, 150) et en fractions non magnétiques (40, 70, 160). Les procédés de l'invention peuvent être utilisés avantageusement pour séparer une quantité importante de matériau non magnétique, telle que silice ou pyrolusite, de l'oxyde de fer utile dans un minerai de fer ou un concentré de minerai de fer. L'invention tire avantageusement profit d'une source améliorée d'oxydes de fer destinés à des usages haute pureté, tels que par exemple, des procédés de réduction directe et des procédés d'enrichissement du charbon en milieu dense.

Title: Antibodies against human il-12
Inventor: GATELY MAURICE KENT
IPC: C12P21/08
Filed: 1999-01-15
Granted: 2012-07-03
Abstract: The present invention relates to p75 heterodimer specific anti-human IL-12 antibodies that are characterized by a higher potency and greater efficacy in neutralizing human IL-12 bioactivity than known heterodimer specific IL-12 monoclonal antibodies. The heterodimer specific antibodies recognize one or more epitopes of the human IL-12 p75 heterodimer, but do not bind to the p40 subunit alone. The heterodimer specific IL-12 antibodies neutralize rhesus monkey IL-12 bioactivity with a potency similar to their potency for neutralizing human IL-12 bioactivity making them useful IL-12 antagonists.

Abstract: A computer system defines a set of electronic catalogs. The catalogs each have an associated contract and each user of the catalogs is associated with a contract. The set of catalogs is represented as a graph. Nodes in the graph represent contracts, catalogs, categories, products and prices. Edges in the graph are labelled with a catalog identifier or a contract identifier. The graph is traversed to display data to the user. The traversal of the graph by a given user is constrained so that the user's contract and catalog matches the edge labelling of the traversal.

Title: Dossier comprenant un renfort en trois parties et des enveloppes transparentes
Inventor: ABBOTT MARC DEAN
IPC: B42D3/00
Filed: 1999-09-15
Granted: 2006-11-14
Abstract: L'invention concerne un dossier (5) ou une reliure de feuillets mobiles qui comprend une nouvelle structure de dos. Cette structure se compose d'une feuille (10) rigide qui présente deux plis (12) espacés l'un de l'autre de manière à former un renfort (20) de dos comprenant des renforts (22, 24) de couverture adjacents.

Title: Wet sprinkler system for cold environments
Inventor: HANKINS JOSEPH
IPC: A62C35/00
Filed: 2000-04-28
Granted: 2008-12-23
Abstract: In a sprinkler system for warehouse freezers or other cold environments (11), a sprinkler system piping (17) is connected to a water supply (23) through a check valve (25) and extends through a freez-ing cold environment to sprinkler heads (13) positioned to discharge extinguishant.  The sprinkler system piping (17) within the cold environment is filled with a so-lution of pottasium lactate. When a fire occurs casing one or more of the sprinkler heads to be activated, the sprinkler heads will discharge the potassium lactate onto the fire. This action will reduce the pres-sure in the sprinkler system piping below that of the water supply so that water flows from the water supply through the sprin-kler system piping through the activated sprinkler heads (13) to be discharged upon the fire.

Title: Looper and cutter drive mechanism for sewing machine
Inventor: SAKUMA KOUICHI
IPC: D05B37/06
Filed: 2001-03-05
Granted: 2008-09-16
Abstract: In a looper and cutter drive mechanism for sewing machine, an upper looper and a lower looper are respectively disposed below a throat plate, respective loop-taker points of these loopers are arranged in the same direction such that the loop-taker points pass a front side of the needle as seen in the stitching direction. The upper looper and the lower looper are driven such that the upper looper and the lower looper perform movements having traces on planes substantially parallel to each other. Due to such a constitution, the looper drive mechanism has both of the lockstitching function and the over-edge stitching function and can perform both functions by a single sewing machine. Further, the rotational movement of an upper shaft of the sewing machine is transferred to the upward and downward movement by way of a motion transfer mechanism which is operated in an interlocking manner with the rotational movement and a fabric edge is cut by an upper cutter which is operated corresponding to the upward and downward movement and a lower cutter which is cooperatively operated with the upper cutter. Here, the upper cutter is slidably guided by a cutter drive portion which is pivotally mounted on a frame . The motion transfer mechanism is connected to the upper cutter by way of a clutch. The clutch transfers power to the upper cutter at the time of performing the cutters of the cutter drive portion and pivotally moves the cutter drive portion to a shunting position and interrupts the transmission of power to the upper cutter at the time of not performing the cutters.
