Description

Regelwiderstand oder Potentiometeri Das Hauptpatent hezieht sich auf -einen Regelwiderstand oder ein Potentiometer, bei dem das auf dem Widerstandsielement oder damit in Berührung stehenden Kontaktele-' menten schleifende Stromabnaluncorgan all seiner eigentlichen Schleifstelle eine die Unebenheiten der Schleifbähn ausgleichende Schicht aus einem Amalgam trägt, das vo-rteilhaft in einer Höhlung des StromabnahmeorZgans untergebracht sein ka:nn. Die weitere Ausbildung und'Verbess-erung derartiger Reg,e,lwid,ers,tänide oder Potentiometer liegt nun gemäß der vorliegenden Er4n-dung darin, daß das Amalgarn aus Silhera:,malgam besteht. Dieses bietet gegenüber den übrigen zählreich-en * Metallamalgamen die- Möglichkeit, durch Bemessung des Silbergehalts jeden gewünschten - Flüssigkeitsgrad mit Leichtigleeit einzustellen, was für die angestrebte Wirkung eines Ausgleichs von Unebenheiten der Schleifbahn und auch für die bequeme und sichere Unterhringung in einer Hö-Mung des Stro-mabnahmeorgains von erheblichem- Vorteil ist.Variable resistor or potentiometeri The main patent refers to -a variable resistor or a potentiometer, in which the current connection organ sliding on the resistance element or contact elements in contact with it- 'elements of all of its actual grinding point carries an amalgam layer that compensates for the unevenness of the grinding track -can be properly housed in a cavity in the power take-off device. The further development and improvement of such reg, e, lwid, ers, tänide or potentiometers is now, according to the present invention, that the amal yarn consists of Silhera:, malgam. This offers advantages over the other zählreich-en * metal amalgams DIE opportunity to every desired by dimensioning of the silver content - adjust fluidity with Leichtigleeit what the desired effect of compensating for unevenness of the grinding path and also for the convenient and safe Unterhringung in a Hö mung of the power consumption organization is of considerable advantage.
