Abstract: Un procede de purification de coulees, consistant sensiblement en metaux non ferreux, de preference du cuivre et du plomb, par elimination des impuretes contenues sous forme d'elements qui ne sont pas separables facilement, tels que le cobalt, le nickel, le plomb, le bismuth, l'antimoine et l'arsenic, consiste a injecter dans la coulee au moins un agent de reaction solide a l'aide d'un gaz porteur. Pendant le procede d'injection, la coulee est maintenue sous l'influence de turbulences importantes. Le gaz porteur et l'agent de reaction solide sont selectionnes de sorte qu'il se forme avec l'element ou les elements d'impurete un produit dont le point de fusion est superieur a la temperature regnant dans la coulee, et qui possede une densite differente de celle de la coulee. Le produit resultant est alors separe de la coulee. Par exemple, la coulee peut etre constituee de cuivre, et les elements d'impurete peuvent etre du nickel et/ou du cobalt, et l'agent de reaction de la silice, qui forme un produit solide avec le nickel et/ou le cobalt. De maniere appropriee, la coulee peut egalement contenir un agent d'oxydation, tel que l'oxyde de fer (III) ou l'oxyde de cuivre. La coulee peut consister egalement en plomb brut et les elements d'impurete peuvent etre de l'antimoine et/ou de l'arsenic. Dans ce cas, l'agent d'oxydation peut etre de l'oxyde de plomb, qui peut egalement jouer le role d'agent de reaction solide pour former un produit solide. D'autres combinaisons sont egalement concevables.

Abstract: A secondary sealing element for axial seal rings, is resistant to stresses due to temperature, pressure, vibration, corrosion, swelling and shrinking. This sealing element is produced of non-rubber-type elastic and non brittle material and its shape, in cross-section, consists of a ring, with a pair of arms to give it an elastic reaction. The double-arm ring forms three radial-type sealing surfaces and is completely locked into a chamber. Special material with low static friction and higher thermal conductivity than rubber material is used. Furthermore the dissipation of heat, produced by the axial sliding rings, will be increased through the double contact area to the shaft by the arms in comparison to an O-ring, and through a wear-resistant and non-corrosive layer on the shaft having at least the thermal conductivity of the basic material.

Abstract: Dans le passe, la commande du cycle de travail pour optimiser la puissance de moteurs a induction etait effectuee avec un thyristor a declenchement de phase et un circuit de commande de mesure de l'angle de phase tension-courant, monte en serie. Ces types de systemes sont compliques et couteux. Dans la presente invention, le rendement optimum est obtenu en utilisant une tension de commande generee par le moteur a induction a roue libre (20) ou ligne (16) pendant les periodes de non conduction d'un thyristor en serie (60). L'angle d'allumage du thyristor (60) varie par la tension de commande augmentant la vitesse de charge d'un condensateur (44) d'un degre variable, lequel condensateur declenche le thyristor (60). Sous une charge mecanique plus grande, la tension de commande du moteur a induction en roue libre (20) diminue, la tension de commande diminuee accelerant la vitesse de charge du condensateur (44) reduisant ainsi l'angle d'allumage du thyristor (60), de sorte qu'on obtient une puissance par cycle moteur (20) plus grande. L'effet inverse se produit lorsque la charge mecanique est diminuee. Par consequent, la presente invention constitue un circuit de commande plus simple et moins couteux pour optimiser le facteur de puissance d'un moteur a induction.

Abstract: The clutch device is suitable for intermittent or freewheeling operation of a vehicle and is particularly intended to prevent operating errors and lapses on the part of a driver when switching off freewheel operation. In this arrangement, a clutch lever (4) can be operated with the aid of a clutch pedal (18) and a controllable piston (6). A hand switch (21) for switching off the automatic freewheel in the open state of the clutch, which is actuated by the piston (6), does not become effective until the clutch pedal (18) is depressed and a contact (19) is closed. Only then does the control release a discharge line (9), so that the piston (6) is unloaded and can be pushed back. Due to the depressed clutch pedal (18), however, in this process the driver directly takes over the movement of the clutch lever (4) via the clutch pedal (18). The driver can then engage the clutch in the usual fashion with the aid of the clutch pedal (18). <IMAGE>
