  • Vacuum arc discharge device with tapered rod electrodes
    Patent number: 4063126
    Abstract: In a vacuum arc discharge device of the rod array type, improved arc diffuseness and enhanced ability to hold off voltage during the recovery period are obtained by tapering the rods, with the maximum diameter occurring near the free ends. A higher threshold current for rod anode spot formation and melting also results.

  • Sheet-wound transformer coils
    Patent number: 4012706
    Abstract: In sheet-wound transformer coils, excessive ohmic losses due to high current density at the sheet edges caused by a radial magnetic leakage field are avoided by adding apparatus adjacent the edges which may comprise individual strips that are transposed as the coil is wound. In one alternative embodiment, the apparatus adjacent the edges comprises separate parallel strips of high magnetic permeability material assembled in conjunction with the coils. In another alternative embodiment, wire-wound coils are employed at each edge of the sheet-wound coils.
