Title: Bi-directional spring holder assembly for an actuator
Inventor: JORGENSEN GREGORY A
IPC: E05B15/04
Filed: 1998-08-05
Granted: 2006-06-27
Abstract: An actuator having a bi-directional spring holder assembly is disclosed. The assembly has a substantially cylindrical housing (42) having a projection (60) formed on a rim of its cylindrical wall (56). The projection (60) is provided with first and second abutments (62, 64) facing in opposite directions along the circumference of the rim (58). A spring (70) is mounted around a shaft which passes through a longitudinal axis of the housing. A first, internal spring end (72) is engaged to the shaft while a second, external spring end (74) projects radially outward of the cylindrical wall (56). The assembly also includes a spring cover (80) provided with a cover abutment (84) which similarly projects radially outward of the cylindrical wall (56). When the holder assembly is assembled, the spring (70) is coiled and the cover abutment (84) pushes against the projection's first abutment (62) while the external spring end (74) pushes against the second abutment (64). The actuator housing is provided with a wall member (48), one side of which forms a stop for the cover abutment (84), while the other side serves as a stop for the external spring end (74). When the gear train is driven, one of the cover abutment (84) and the external spring end (74) abut a corresponding stop, and the entire housing (42) rotates with the output lever, causing the spring to coil. The coiled spring then provides a restoring force, returning the output lever to the neutral position.

Les valeurs d'échelle de gris correspondant à l'image sont stockées dans une mémoire (38). La composition des fréquences spatiales des valeurs de l'échelle de gris est analysée de façon à déterminer la quantité de pluie présente et afin de délivrer un signal de commande permettant de commander les essuie-glace (40) du véhicule en fonction de la quantité d'humidité présente. Ce système est également conçu pour détecter le niveau de buée à la fois sur la face intérieure du pare-brise (26) et sur la face extérieure du pare-brise (26). Ce système qui assure la détection automatique de la présence de buée sur les faces intérieure et extérieure du pare-brise (26) permet d'éliminer les sérieuses restrictions de performance des détecteurs de pluie automatiques connus à ce jour.

Title: Method and apparatus for continuous casting of metals
Inventor: YAMANE HIROSHI
IPC: B22D11/00
Filed: 2000-11-14
Granted: 2010-01-26
Abstract: During continuous casting of metals, a non-moving, vibrating magnetic field is applied to a molten metal in a casting mold to impose only vibration on the molten metal. This continuous casting method can produce a cast slab much less susceptible to flux entrainment, capture of bubbles and non-metal inclusions near the surface of the molten metal, and surface segregation. The magnetic field is preferably produced by arranging electromagnets in an opposing relation on both sides of the mold to lie side by side in the direction of longitudinal width of the mold, and supplying a single-phase AC current to each coil. The single-phase AC current preferably has frequency of 0.10 to 60 Hz. A static magnetic field can be applied intermittently in the direction of thickness of a cast slab. This technique can produce a cast slab substantially free from the flux entrainment and the surface segregation. Preferably, the static magnetic field is intermittently applied under setting of an on-time t1 = 0.10 to 30 seconds and an off-time t0 = 0.10 to 30 seconds. Also, the static magnetic field is preferably applied to the surface of the molten metal.

Title: Neutral brake
Inventor: JOLLIFF NORMAN E
IPC: B60W30/18
Filed: 2001-01-19
Granted: 2004-11-02
Abstract: A neutral brake system for use in a hydrostatic transmission to automatically apply a brake when the hydrostatic transmission is shifted to neutral. The neutral brake system includes a hydraulically-released, spring-activated brake mechanism in direct fluid communication with the main hydraulic passages which form a hydraulic circuit between the pump and the motor. When the hydrostatic transmission is shifted to neutral, a brake spring biases a brake lever into contact with a pair of friction pads to engage a brake disk splined to the output shaft of the motor to stop the vehicle. When the hydrostatic transmission is shifted out of neutral, a charge of hydraulic pressure within the hydraulic circuit causes a piston within a brake release chamber to override the biasing force of the brake spring, and to urge the brake lever out of contact with the friction pads such that the friction pads are disengaged from the brake disk, and the output shaft of the output shaft of the motor may freely rotate. A throttling orifice is provided in the hydraulic circuit to restrict hydraulic flow from the brake release chamber to prevent abrupt engaging of the brake mechanism when the transmission is shifted to neutral.

Title: Procede d'extraction par voie aqueuse utilise pour eliminer selectivement les phospholipides des jaunes d'oeufs
Inventor: BALL HERSHELL R JR
IPC: A23L15/00
Filed: 1999-06-30
Granted: 2004-05-11
Abstract: Le procédé d'extraction par voie aqueuse utilisé pour éliminer sélectivement les phospholipides des jaunes d'oeufs comprend en général l'utilisation d'un procédé par voie aqueuse pour séparer la majeure partie des protéines présentes dans le jaune d'oeuf au moyen de la force ionique, du pH et des forces centrifuges par gravité. Le procédé commence par la séparation des jaunes d'oeufs et de l'albumine. Le jaune d'oeuf est ensuite mélangé avec de l'eau pour diluer le jaune d'oeuf sous forme d'une fraction jaune dilué (JD). On ajuste ensuite le pH du jaune d'oeuf mélangé par addition d'acides, de bases et/ou de sels. Le jaune d'oeuf mélangé à pH ajusté est ensuite exposé à une séparation par gravité à l'aide d'une centrifugeuse pour obtenir des couches de fraction surnageant (SUR) et de fraction précipité (PRE). La fraction SUR est ensuite séparée de la fraction PRE. Des agents de viscosité sont alors ajoutés à la fraction SUR et le mélange est effectué. La fraction SUR est soumise à des forces de séparation par gravité pour former une fraction crème (CRE) et une fraction aqueuse. La fraction CRE est ensuite séparée de la fraction aqueuse pour obtenir la séparation désirée des phospholipides. Le procédé de cette invention peut également utiliser un régime d'alimentation à base de graines entières de soja et de graines de lin extrudées pour des poules pondeuses afin d'augmenter la concentration d'acide gras oméga 3 (acide docosahexanoïque) dans le jaune d'oeuf à son stade initial.

Abstract: An image forming apparatus uses an ink ribbon (7) having a plurality of ink layers (72) of different colors, and a long, film-like intermediate transfer medium (6). A platen (10) for holding the intermediate transfer medium (6) during transfer is driven by a motor (50) via a synchronous reduction gear (51 - 58) whose speed reducing ratio is an integer multiple.      The ink ribbon (7) is selectively heated by a thermal head (38) having substantially regular polygonal or substantially circular heat-generating portions (38a).      Under the control of a controller (C1), the thermal head (38) is driven on the basis of image information, and a record image containing an area gradation image is formed on the intermediate transfer medium (6).      This area gradation image has a color set by stacking dots having different colors in substantially the same spot. The intermediate transfer medium (6) on which the record image is formed is overlapped on a target body (1) and heated and pressed by a heat roller (40), thereby transferring the record image from the intermediate transfer medium (6) onto the target body (1).
