Utility
Feedthrough device
27 Jul 20
A feedthrough device includes a body having longitudinally spaced first and second end faces and an inner surface defining an opening extending longitudinally through the body, a conductor extending within the opening of the body, and an insulator extending within the opening of the body transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body, where the conductor includes an interior portion surrounded by the insulator and an exterior portion extending beyond the insulator, the exterior portion having a diameter that is greater than a diameter of the interior portion.

Utility
Method of manufacturing a metal-air cell
20 Jan 20
The invention includes a method of making a catalytic electrode for a metal-air cell in which a carbon-catalyst composite is produced by heating a manganese compound in the presence of a particulate carbon material to form manganese oxide catalyst on the surfaces of the particulate carbon, and then adding virgin particulate carbon material to the carbon-catalyst composite to produce a catalytic mixture that is formed into a catalytic layer.
