    Abstract: A variable resistance controller for electrical braking systems and the like wherein the form on which the resistance wire is wound has spaced apart flats into which some of the coils are drawn during winding. This arrangement provides alternate lands and depressions over which a leaf spring type contact rolls. The preferred arrangement has only two coils per land to give increased contact pressure of the leaf spring therewith and to provide predetermined incremental increases in electrical output as the leaf spring rolls from one land to the other. In the preferred embodiment, the spacing of the lands is arranged so that the electrical output is proportional to the hydraulic actuating pressure.The preferred embodiment also includes a diode connected between the output of the controller and ground through a fusible link to permit the collapsing magnetic field of the controlled braking electromagnets to draw current through the diode on deactuation of the unit to bypass the wound resistor. This reduces arcing and increases service life.

    Abstract: A D.C. potential controller is provided for controlling the magnitude and polarity of a D.C. potential applied to a D.C. drive motor. The controller includes a supply device for producing a potential having a predetermined polarity and magnitude and including a first fixed terminal referenced to said predetermined polarity and potential and a second fixed terminal referenced to a reference potential. A regulating element is displaceable between first and second polarity selecting positions, and is further coordinately displaceable from either first or second polarity selecting positions through a third position. The regulating element also includes first and second moving contacts disposed thereon in spaced apart relationship for contact with the first and second terminals, first and second fixed output current terminals are respectively disposed in contact with the first and second moving contacts when same are displaced through the third position, the first output current terminal including circuitry for linearly varying the output current in the first output current terminal in response to the aforesaid coordinate displacement of the regulating member.
