  • Patent number: 11145925
    Abstract: The disclosed technology relates to an electrical feedthrough for a cylindrical battery cell. The electrical feedthrough may include an annular channel having an outer sidewall, an inner sidewall, and a base; an insulator formed of glass having an overmold portion; and a pin extending through the insulator and configured to form an external battery terminal. The insulator is bonded to the inner sidewall of the annular channel and a portion of the base of the annular channel. The overmold portion prevents electrical contact between a set of electrodes and the electrode feedthrough.

  • Publication number: 20040238464
    Abstract: A dish rack draining tray that includes a sloped trough having an exit end at the front side of the draining tray. The slope in the trough allows fluid to flow and discharge off the exit end of the trough on the front side of the draining tray. The draining tray includes one or more sloped surfaces that allow the fluid collected on the sloped surfaces to run off into the sloped trough. These sloped surfaces also support a dish rack on a horizontal plane.
