Inventor: CONRY RONALD DAVID
IPC: H02K1/27
Filed: 1998-01-28
Abstract: La présente invention concerne un rotor (10), et plus particulièrement un rotor de moteur électrique grande vitesse, comportant un noyau magnétique (12) en terre rare à l'intérieur d'un manchon (14) formant l'arbre du rotor. Le noyau (12) est soumis à une compression axialement comprimé s'exerçant entre des pièces d'extrémités opposées (16, 18) fixées au manchon par soudure, par collage ou par thermorétraction. Le noyau peut également être soumis à une compression radiale. Le procédé d'assemblage du rotor (10) consiste en une opération de compression axiale du noyau (12) entre les pièces d'extrémités (16, 18) et une opération de fixation du manchon (14) aux pièces d'extrémités (16, 18) pendant que le noyau (12) est soumis à précontrainte.

Inventor: SCHOENFISCH MURRAY
IPC: G01F22/00
Filed: 1998-04-21
Abstract: An apparatus (26) for measuring the flow of a particulate or clumpy material such as cotton (24) includes a transmitter array (28) and a receiver array (30) spaced on opposite sides of a flow path of a chute (18) through which the cotton (24) travels. The transmitter array (28) is pulsed at a particular rate and the receiver array (30) sampled synchronously with the pulsing of transmitter array (28). Controller (32) determines how many of the receivers in array (30) were blocked from receiving signal from corresponding transmitter array (28) by impeding clumps of cotton (24). From this, a digital signal is produced and the controller (32) can calculate an instantaneous volume of cotton (24) in accordance with the algorithm F=KS where F is the volume, S is the digital signal and K is a calibration constant.

Inventor: SAMUNEVA BISERKA I
IPC: C03C3/097
Filed: 1990-05-09
Abstract: Niobium-containing, silicate glass is used for preparing optical elements in optics and apparatus construction. It is derived at a melting temperature that is about 150 to 180 degrees C lower than that needed for glass production following by traditional method : with oxide blend. To produce glass (with a composition in molecules % of the following : silicon dioxide (50-80), diniobium pentaoxide (5-10) and potassium fluoride (5-35) or barium fluoride (5-30), the following raw materials are used : a solution of the silicon sol, finely-dispersed dust of diniobium pentaoxide (measuring between 5 and 10 microns), and a water solution of potassium or barium fluoride. Diniobium pentaoxide, which is homogenized into the solution, is added to the sol of the silicon acid by incessant mixing, thus ensuring silicon dioxide in the necessary quantity. A water solution of barium or potassium fluoride is added to the mixture, after which the solution is gelled. After drying and grinding, the dust-like mixture is melted at temperatures between 1,200-1,300 degrees C, with retention from 1 to 2 hours.

Title: Test immunologique en tandem pour le depistage du cancer
Inventor: PULIDO-CEJUDO GABRIEL
IPC: G01N33/574
Filed: 2000-03-30
Abstract: L'identification et la caractérisation de facteurs de risque et leurs implications moléculaires dans la pathophysiologie de maladies humaines comme le cancer sont essentiels pour concevoir des tests diagnostiques et des composés thérapeutiques efficaces. Des stéroïdes oestrogènes, dans des conditions physiologiques normales, ont joué un rôle critique dans plusieurs tissus. La réponse d'une telle variété de tissus à la stimulation oestrogène peut expliquer en partie leur rôle actif dans le développement et l'évolution de différentes maladies humaines, notamment le cancer du sein. On a identifié deux marqueurs cellulaires et une isoenzyme de leucine aminopeptidase présumée (LAPase; EC 3.4.11.1) issue de cellules parentales de cancers primaires du sein issues de biopsies tumorales et une NDP-Kinase/Nm23 (EC 2.7.4.6) cytocyclique dérivée de cellules HL60 en recherchant des facteurs cellulaires à réponse oestrogène dans les cellules parentales de cancers primaires du sein provenant de biopsies tumorales. Des anticorps monoclonaux luttant contre chaque marqueur cellulaire sont apparus. La détermination de la présence de ces deux marqueurs, seuls ou combinés, peut servir à dépister un cancer du sein et plus particulièrement une métastase associée. Ainsi, cette invention concerne l'utilisation de ces anticorps monoclonaux de LAP et NDP-Kinase/Nm23 dans un test immunologique matrice-solide en tandem en vue de l'analyse sanguine de première intention et de confirmation du cancer du sein.

Title: Method of manufacturing a belt pulley
Inventor: BICHEL JOACHIM
IPC: B21D53/26
Filed: 1990-05-17
Abstract: The invention relates to a method of manufacturing a belt pulley consisting of a metal disc, such as a poly-V-belt pulley, a toothed belt pulley, a flat belt pulley etc., having a hub and a region whose basic shape is a hollow cylinder, which is externally smooth or cambered, or is provided with a profile running in the circumferential or lateral direction, and whose material thickness can be greater than that of the hub, the metal disc being profiled in a corrugated shape in its circumferential region in a first step of the method and the respective finished profile being produced in further steps of the method. 
<??>Known methods require a large number of process steps and a large amount of force for forming. The new method is intended to allow high- quality belt pulleys to be produced from metal discs with a comparatively low outlay for carrying out the method. 
<??>The new method is characterised in that, in a second step of the method, the circumferential region (11), profiled in a corrugated shape, of the metal disc (1) is rolled into a shape, which is corrugated when seen in cross-section, with a corrugation maximum (12, 12') in each case on the edge side, pointing outwards in the radial direction, and laterally adjacent wave minima (13, 13'), pointing inwards, so that a contour is produced having a corrugated shape with optimum material distribution for further processing.

Abstract: Continuous Casting of Ingots Abstract In the embodiments described in the specifica-tion, continuous casting of ingots is carried out by transferring molten metal from a hearth (35) to a mold (34) through one or more flow channels (38) which provide flow paths having a shallow angle to the hori-zontal and which terminate adjacent to the surface (41) of the molten metal (40) in the mold (34) so that the vertical velocity component of the stream of molten metal flowing into the mold is minimal and the horizontal velocity component is low.  In one form, the hearth (33) surrounds the mold (34), providing four shallow-angle flow channels (38) uniformly spaced around the periphery of the mold (34) to avoid unilat-eral introduction of the molten material into the mold.
