Klaus Rudiger Petrikat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Glass encapsulated capacitor with pressure connected cathode lead
    Patent number: 3947735
    Abstract: An electrolytic glass encapsulated capacitor has a pressure connection to the cathode lead. The glass envelope includes a sintered body having a dielectric oxide layer, semiconductor and conducting layers. A porous deformable metal layer is sprayed on the conducting layer adjacent the cathode lead which extends through the glass. The cathode lead is pressed into the deformable layer to provide an improved connection.

  • Capacitor with glass metal conductive layer
    Patent number: 3935516
    Abstract: A glass-metal powder mixture, preferably including silver, is used in place of the usual epoxy resin-silver outer layer of a tantalum capacitor. This reduces temperature sensitivity during soldering and avoids penetration of silver into the graphite and manganese dioxide layers of the capacitor. Thinner layers of graphite and MnO.sub.2 can be used and reduced carbonization provides improved conductivity. A small solder bead can also be used instead of dipping into a solder bath.
