Abstract: Ce système d'extinction d'arcs pour contacts électriques comprend un transistor, un IGBT par exemple, qui est connecté entre les contacts. Un circuit de commande gère le fonctionnement du transistor de telle sorte que l'activation dudit transistor se traduit par un chemin de courant autour des contacts, ce qui a tendance à empêcher la formation d'arcs entre ces contacts. Un détecteur de courant tel qu'un transformateur de balayage horizontal est monté en série avec les contacts. Lorsque les contacts s'ouvrent, le passage du courant est interrompu dans ces contacts et dans le transformateur, une seconde tension se crée qui est appliquée au transistor et tend à le maintenir enclenché pendant un laps de temps suffisant pour permettre aux contacts soit de s'ouvrir, soit de se fermer, en l'absence d'arc.

Title: Recovery of platinum group metals
Inventor: BAX ALAN
IPC: C22B3/20
Filed: 2004-04-08
Granted: 2012-08-07
Abstract: ABSTRACT A process of recovering platinum group metals (PGMs) from a pregnant solution or leachate containing PGM values and base metals, typically a cyanide solution or leachate. A non-selective precipitation of the PGM values and base metals to form an insoluble precipitate comprising the PGM values and base metals is followed by selective leaching of the precipitate. The selective leaching forms a leach solution containing the base metals and a residue containing the PGM values, or a leach solution containing the base metals and PGM values and a depleted residue. The base metals are recovered from the leach solution and the PGM values are recovered from the residue or the leach solution, depending on the selective leaching. The non-selective precipitation of the PGM values and base metals is carried out by controlled reduction of the pH of the pregnant solution or leachate to a pH of about 2.

Title: Tire balancing apparatus
Inventor: WILLIAMS THOMAS D
IPC: G01M1/06
Filed: 2005-04-13
Granted: 2010-09-21
Abstract: A machine and method for performing balancing measurements on a tire or tire/wheel assembly that includes a structure defining spaced apart tire centering and tire testing positions. A first conveyor moves a tire to a centering position where a shuttle assembly is operative to center the tire and, after it has been centered, engages the tire and effects the transfer of the tire from the centering station to a testing station. The shuttle assembly includes a pair of grippers that move towards and away from each other, in a lateral direction in order to engage the tire. The first conveyor permits movement of the tire in a lateral direction; whereas it substantially resists relative movement between the tire and conveyor in the longitudinal direction, i.e., and the direction of movement of the conveyor. The shuttle assembly is mounted for movement in a longitudinal direction and includes a drive mechanism which allows the shuttle assembly to move relative to a tire in a longitudinal direction as the grippers engage the tire so that the shuttle assembly can align itself, in the longitudinal direction with respect to the tire. The frame structure of the machine includes three spaced apart support members providing a three-point support arrangement for the machine. The machine also includes at least four legs, which extend downwardly, but are spaced above a plane defined by the support members and inhibit tipping of the machine beyond predetermined limits. The testing station, which includes a spindle assembly for rotating the tire also, includes an elevator mechanism for lowering the tire on to the spindle and for raising the tire off the spindle. A lower marking mechanism forms part of the elevator and is operative to mark a predetermined location on the tire at the conclusion of a tire testing procedure. The spindle assembly includes a drive motor comprised of a drive motor housing and an armature. The armature is maintained in its operative position by a bearing arrangement associated with a shaft assembly forming part of the spindle assembly which eliminates the need for armature supporting bearings in the drive motor housing.
