Abstract: A crankshaft decoupler (10) has a mounting hub (12), a pulley (14) rotatably mounted on the mounting hub (12), an annular carrier (26) mounted within said pulley (14), a biasing device (38) mounted therebetween, and a one way clutch (40) mounted between the annular carrier (26) and the pulley (14). The biasing device (38) cushions the belt drive from crankshaft impulses and lowers the angular resonant frequency of the belt system. The one way clutch (40) prevents sudden reversal of the belt tension in the drive due to start/stop of the engine or sudden deceleration of the engine and prevents momentary reverse slip belt squeal as a result of the tensioners' inadequate output for the reverse mode. The one way clutch (40) limits the maximum amount of torque which may be transmitted preventing belt slippage during momentary overload.

Abstract: Cette invention concerne plusieurs types de transformateurs, lesquels peuvent être utilisés en qualité d'équipements électrotechniques principaux dans des centrales électriques, des centrales secondaires, des lignes d'alimentation électriques, ainsi que dans le domaine des techniques radio et dans des dispositifs de mesure, de commande et de contrôle automatiques. Le principe de ces transformateurs repose sur le fait que l'enroulement primaire se compose de deux sections. Ces sections sont enroulées et connectées entre elles de manière à ce que, lors du fonctionnement du transformateur, le flux magnétique généré par l'une de ces sections puisse compenser le flux magnétique généré par l'autre section de l'enroulement primaire. Ce transformateur comprend un conducteur magnétique ainsi qu'un enroulement primaire se composant de deux sections. Ces dernières sont enroulées autour de la tige du conducteur magnétique dans une direction donnée, et possèdent un même nombre de spires. Les enroulements des deux sections sont reliés entre eux par leurs fins tandis que les débuts servent de source d'alimentation. Le second enroulement, auquel on applique une charge RH, est enroulé sur le premier et autour de la tige de ce même conducteur magnétique. Les différentes variantes de ces transformateurs se caractérisent, une fois mises en oeuvre, par le fait que les sections de l'enroulement primaire sont enroulées sur une tige de conducteur magnétique (3 variantes) ou sur les deux tiges d'un conducteur magnétique (4 variantes). Ces transformateurs se caractérisent également par le sens d'enroulement des sections (dans un sens donné ou dans le sens opposé) et, donc, par une connexion différente des enroulements. Ces transformateurs se caractérisent enfin, dans une variante, par la présence de l'enroulement secondaire et par l'absence de l'enroulement primaire.

Filed: 1997-02-28
Granted: 2006-01-24
Abstract: A coin conditioner is provided for cleaning or otherwise conditioning coins in a coin discriminator apparatus prior to transfer to a coin sensor.   Coins enter through a feed tray (1302) and move down the length of a perforated tumbler (1314), preferably without the use of gravity, such as under screw force, mechanical or centrifugal force. The spinning tumbler is preferably rotated about its longitudinal axis by a motor (1352). In one embodiment, a blower or vacuum draws or moves air from one area to another, with the air preferably being filtered. As coins move through and down a tumbler, projections such as vanes (1922a), fins, ridges, dimples (1820), spines or other raised features cause mechanical agitation and/or abrasion as coins are lifted and dropped while passing longitudinally ~ through the tumbler. The coins are conditioned and non-coin matter is collected as it is separated and/or abraded from the coin surfaces.
