Harold Younger 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).

  • Method of forming a transformer winding with rectangular copper wire
    Publication number: 20050034296
    Abstract: A preferred method for forming a transformer winding includes providing a length of copper wire having a substantially circular cross section, flattening the length of copper wire in two dimensions on a substantially simultaneous basis, and winding the length of copper wire into a first layer of adjacent turns.
    Type: Application

  • DC voltage/current heating/gelling/curing of resin encapsulated distribution transformer coils
    Patent number: 6624734
    Abstract: An internal heating method for drying, gelling and final curing of epoxy resin insulation systems used for encapsulating dry type cast distribution transformer coils is disclosed. The internal method uses a Direct-Current (DC) power source to control and supply DC current to resistively heat the transformer coil encapsulated with a liquid resin under vacuum in a mold. DC current is applied to a given coil based on its conductor cross-sectional area and its epoxy resin quantity to achieve a specified temperature for drying, gelling and final curing. The temperature, controlled by DC resistive heating is maintained for a given period for each step.

  • Method and apparatus for production of continuous metal strip
    Patent number: 5829298
    Abstract: Twin metal billets are fed to dual circumferential grooves formed in a rotating wheel. The billets are advanced first to a wedge-shaped gap which deforms the billets and are then advanced to a die. The die has a die opening with a circumferentially discontinuous, annular cross-section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube. The tube is then opened and flattened to form a flat strip by advancing the slit tube over a forming member having a progressively increasing width.
