Abstract: .Iadd.A rotary potentiometer with speed reduction gearing. A multi-tap closed loop distributed impedance is coupled by a mechanical configuration including a shaft to selected taps on an autotransformer. The mechanical coupling configuration permits the output from the wiper on the closed loop distributed impedance to change as a function of shaft position and to jump from one end of the autotransformer to the other while the shaft is continuously rotated in a given direction. .Iaddend.

Abstract: A potentiometric sensor, comprising: a potentiometer track; a collector track opposite the potentiometer track; a conductive magnetic cushion slider coupled to the potentiometer track and the collector track; and a sealed body housing the potentiometer track, the collector track, and the conductive magnetic cushion is disclosed. The potentiometric sensor may provide a variable output voltage indicative of a level of liquid in a container. The output voltage of the potentiometric sensor may be based on a position of a magnet, which may determine a position of the conductive magnetic cushion or a ferromagnetic spring. The magnet may be outside of the sealed body. As the sensor will be more cost effective and less space consuming, the totally sealed sensor incorporating the conductive magnetic cushion or a ferromagnetic spring may replace many applications that allow a hysteresis of less than 1 mm. Additionally, these applications may be used on rotary systems.

Abstract: A thick-film potentiometer having a support substrate, particularly a ceramic substrate, onto which there is applied at least one resistance track of resistance composition which is electronically contacted via conductor lines on the support substrate at its ends and under circumstances at contact points therebetween and having a wiper track which extends along the resistance track and over which a wiper is swingable. The wiper track is formed of a plurality of the conductor lines which are narrow compared with the length of the wiper track and are arranged, spaced apart from each other, substantially at right angles to the wiper track, and the resistance track is arranged on the support substrate exclusively outside of the wiper track beyond and adjacent to the conductor lines.

Abstract: A unitary resistor film and shunt and a method of producing same for use as a resistor element per se or as the resistance element of a linear, nonlinear or characterized potentiometer. A conductive material is screened and fired onto the resistor film at a location that is spaced inwardly of end portions of the resistor in such a manner that a negligible amount of diffusion occurs between the conductive and resistive film material to thereby reduce the resistivity of the resistor film, e.g., ten fold without incurring any change in its original size, temperature coefficient of resistivity or stability.

Abstract: The invention includes tap electrodes comprising a plurality of resistance layers connected in series but different in width before and after the joint portions, and a sliding contacting member comprising a great number of small contacts. Either or both of the elongated directions of the electrodes and contacting member are relatively inclined. By this arrangement the variation in resistance is ideally stepwise and this stepwise variation is held stable regardless of the increase in the number of sliding operations of the slider.
