  • Patent number: 4443829
    Abstract: In a capacitor of the wound metallized dielectric type, a section of resistive material is provided on a film forming the metallized dielectric, and this resistive material extends across the film's entire width (the axial dimension of the capacitor). A metal contact for one of the capacitor plates is sprayed on either end of the capacitor so as to touch one end of the section of resistive material, thereby creating a resistive shunt across the plates formed on the metallized film. The section of resistive material is preferably carbon-loaded paper which is secured over an unmetallized area to the film used to make the capacitor. The paper projects beyond either lateral edge of the film so that spraying metal on the ends of the capacitor causes the ends of the paper to be connected to respective capacitor plates.

  • Patent number: RE30775
    Abstract: An automatic capacitor winding machine has a retractable bifurcated arbor and vertically movable clamps to grasp the ends of the capacitor dielectric layers and carry those ends to a point below the retracted arbor. The bifurcated arbor is registered in its retracted state with its slot parallel to the dielectric layers. The arbor is then extended and grasps the dielectric layers between its tangs. The pressure grasping the dielectric layers is partially removed to allow the arbor to rotate and pull the dielectric layers from between the clamps. A stripper washer is provided to freely rotate on the arbor with limited movement parallel to the axis of the arbor and with a relatively small clearance between the washer's inside surface and the arbor's outside surface. Photoelectric means are provided to accurately detect the location of the first tab (terminal) to time the insertion of the other tabs. A reciprocating blade severs the dielectric layers after the capacitor is wound.
