Patents by Inventor Daniel Featherstone

Daniel Featherstone 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).

  • Edge-wound resistor, resistor assembly, and method of making same
    Patent number: 9396847
    Abstract: A resistor, resistor assembly, and a method of making them are described, with advantages over existing resistors, resistor assemblies, and methods. The resistor includes a helical resistor element wound on an insulator. The insulator has a regularly spaced plurality of teeth on each of two opposite sides, with the helical resistor element situated within the teeth. The insulator provides support for the helical resistor element without use of a separate core within the insulator. The resistor may be assembled by inserting two toothed insulator pieces into a helical resistor element and separating the two insulator pieces such that turns of the helical resistor element are within the teeth of the first and second insulator pieces. Alternatively, the resistor may be assembled by winding a helical resistor element onto a toothed insulator piece.
