  • Patent number: 3948736
    Abstract: A novel method for the selective electrodeposition of a metallic coating onto a base material and the products produced thereby. In the method of the invention, a thin adherent coating of an electrically conductive material is initially applied to the base material to mask off those portions of the material not to be electroplated. The composite thus formed is then placed in a suitable electroplating apparatus wherein a metallic coating such as gold or other precious metal is electrodeposited onto the portions of the composite not covered by the masking material. After electroplating, the masking material may readily be removed from the base material by chemical or mechanical means, or it may be left intact on the plated article to perform a utilitarian or decorative function in the end product application.

  • Patent number: 3932070
    Abstract: In an electric motor fan unit, a motor section frame enclosing a motor ventilating fan moving air through an internal motor cooling air path includes an end bracket with an enlarged rim for mounting fan shell and interior partition structures defining a fan section housing with a chamber for a working air centrifugal impeller mounted on the motor shaft outboard of the end bracket and drawing a working air stream into a housing axial inlet for discharge at the housing circumference, and with an inner chamber for a slinger disk on the shaft to afford bearing protection from working air borne moisture, contaminants, and high temperature and humidity, by simple, low cost, durable structure.
