Patent CA-2274913-C (CA)
Title: Generateur de courant alternatif pour vehicules
Inventor: SHIGA TSUTOMU
IPC: H02K5/15
Filed: 1997-10-17
Granted: 2002-12-10
Abstract: Cette invention concerne un générateur de courant alternatif pour véhicules, dans lequel le noyau du stator (32) possède une forme cylindrique qui est obtenue en enroulant en spirale une tôle d'acier de type bande à l'état laminé. La section du moyeu du noyau (32) est maintenue en place entre deux cadres. Une section axiale renfoncée et de type gorge (38) est formée sur la périphérie externe du noyau (32), un boulon traversant (13) étant introduit à travers cette section (38). Lorsque la position du centre axial du boulon (13) est indiquée, les composantes de quantité de mouvement peuvent être grandement réduites au moment où l'on serre ledit boulon (13) dans le sens axial, ce qui permet d'éviter que ce dernier ne se déserre. On obtient ainsi un générateur de courant alternatif pour véhicules qui ne présente pas de chute de puissance en sortie, qui possède une taille réduite et une excellente résistance aux vibrations, qui ne génère qu'un faible bruit et qui peut être produit à faible coût.

Abstract: La présente invention concerne un procédé de production de lait écrémé stérile du point de vue commercial. Après séparation, la fraction de lait écrémé est traitée par microfiltration en une ou en plusieurs étapes. La microfiltration donne un flux de perméat et un flux de rétentat dans lesquels tous les microorganismes d'une taille donnée ont été séparés efficacement du flux de perméat. Après la microfiltration, le flux de perméat est traité à chaud à une température comprise entre 72 et 134  DEG C pendant une durée appropriée. Afin d'obtenir un lait écrémé stérile à la fois bon et exempt des microorganismes détruits, on n'utilise pas le flux du rétentat.

Title: Heater door safety interlock for infant warming apparatus
Inventor: BELSINGER HARRY E JR
IPC: A61G11/00
Filed: 2000-03-13
Granted: 2008-05-13
Abstract: An infant warming apparatus that functions both as an infant incubator as well as an infant warmer. The apparatus has a heater that moves vertically with respect to an infant support during the change in function between an infant incubator and infant warmer. A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions. The heater also has a door or doors that are open when the heater is in it upper position so that the heater can direct energy toward the infant to warm the infant when acting as an infant warmer. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel. A safety interlock system is provided that prevents the heater from being activated unless it is in its upper position and the door or doors are fully open. In addition, the interlock system also monitors the downward movement of the heater and discontinues that downward movement if the heater reaches a predetermined position and the door or doors are still in the open position. As a further interlock safety feature, a sensor also senses when the heater has reached its lower position and stops further downward movement of the heater.

Title: Electromagnetic actuator
Inventor: LAMMERS AREND JAN WILLEM
IPC: H01H51/22
Filed: 1998-09-07
Granted: 2008-10-14
Abstract: Electromagnetic actuator for moving a contact into a switched-on or switched-off state, comprising a contact-actuating rod which is displaceable in the longitudinal direction between a first position, corresponding to the switched-off state, and a second position, corresponding to the switched-on state. A core which is made of magnetizable material and interacts with a switch-on coil is attached to the contact-actuating rod. Also present is a pole piece which is made of magnetizable material and of which that face which is directed towards the core, in the first position of the contact-actuating rod, is arranged at an air-gap distance from that surface of the core which is directed perpendicular to the direction of displacement, and in the second position bears as closely as possible against the said core surface. The actuator furthermore comprises a yoke made of magnetizable material for closing the magnetic flux circuit of the switch-on coil through the pole piece and the core. A permanent magnet device is used to maintain the contact-actuating rod in the first position, while a spring preloads the contact-actuating rod, in its second position, towards the first position. The actuator is provided with a switch-off coil which, for the purpose of moving the contact-actuating rod fromthe second position to the first position, is excited in order to eliminate the magnetic field of the permanent magnet device at least temporarily, the magnetic flux circuit of the permanent magnet device being separate from that of the switch-on coil.

The inverter (38) receives command signals for the fundamental frequency d and q axis currents (40, 41) and higher frequency voltage command signals (42) from a position and velocity observer (43). The position and velocity observer (43) uses information from the signals (44, 45) to provide estimates for the rotor position and speed provided as output signals (47, 48). The direct field oriented controller (50) includes a flux regulator (58), a torque calculator (60) and a rotor flux observer (61) and provide the inverter (38) with the fundamental frequency current command signals (40, 41). Conventional induction motors can be provided with sufficient spatial variations in the stator winding impedance as a function of rotor position by varying the depth and/or width of the slots over the rotor conductive bars or by varying the cross-section of the bars, or by filling or partially filling some of the slots.

Filed: 1998-04-29
Granted: 2007-07-24
Abstract: L'invention porte sur un procédé de préparation par microfiltration d'un colostrum exempt de bactéries. Ce procédé consiste à verser le colostrum naturel (premier lait) dégraissé dans un réservoir d'équilibre. Puis, la pompe d'alimentation pompe le concentrat pour l'envoyer vers une pompe d'amorçage qui fait circuler ce concentrat à travers une membrane de filtration, la différence de pression dans la membrane rendant possible la filtration du concentrat. Ce concentrat s'écoule dans une unité de chauffage/refroidissement de façon à conserver une température de traitement constante avant de revenir à la pompe d'amorçage. Le colostrum filtré (filtrat) circule dans la membrane de filtration de façon à conserver une pression transmembranaire constante, puis le filtrat est drainé sans perte de pression sur le côté du filtre.

Title: Outil a diamant
Inventor: YOON SO YOUNG
IPC: B23B51/00
Filed: 2002-02-25
Granted: 2007-06-26
Abstract: L'outil à diamant sert à couper ou à percer des substances friables telles que la pierre, la brique, les structures de béton ou d'asphalte. Dans l'outil de diamant, les segments sont munis de diamants disposés sur une seule couche ou sur plusieurs couches montées en alternance ou par intermittence sur une âme d'acier, différemment des outils à diamant conventionnels où les diamants sont fixés en ordre aléatoire sur les segments. La disposition des diamants de cette invention en augmente l'efficacité de coupe. Cela en augmente la vitesse de coupe tout en réduisant les débris de coupe ou de perçage, d'où des conséquences moindres pour la santé des travailleurs et la pollution de l'environnement. Sur les segments, chaque ensemble de diamants étant disposé sur une seule couche ou plusieurs couches, le segment arrière trace des entailles à la surface de la substance friable en laissant un talon entre les entailles.
