  • Method for joining transformer coil conductors
    Patent number: 5104028
    Abstract: A method of joining transformer winding conductor cables is disclosed. The ends of the conductor cables to be joined are first chamfered to both clean and taper the respective ends. The tapered ends are then overlapped and pressed together. Vibratory energy is then applied to at least one of the overlapped ends to weld the cleaned conductor cable ends together to form a joint that has substantially the same cross sectional area as the conductor cables themselves.
    Type: Grant

    Inventors: Paul W. Martincic, Frank W. Benke
  • Vapor-cooled electrical apparatus
    Patent number: 4276530
    Abstract: A water collector for vapor-cooled electrical apparatus which is hermetically sealed to the atmosphere. The flow of vapor through the water collector is generated by the condensation of the vapor into a liquid and is continuous during operation of the apparatus. A storage chamber may be sized to contain all of the water collected during the lifetime of the apparatus or the water may be periodically eliminated from the system.

  • Vaporization cooled electrical apparatus
    Patent number: 4173746
    Abstract: Electrical apparatus cooled by dielectric fluid which vaporizes within the normal operating temperature range of the electrical apparatus. The electrical apparatus includes a plurality of fluid flow passages extending vertically therethrough which have widths within the range of approximately 0.010 inch to approximately 0.060 inch. The small width of the fluid flow passages causes the dielectric fluid to uniformly coat or wet both wall surfaces of the passages as it flows therethrough.

  • Vaporization cooled electrical apparatus
    Patent number: 4129845
    Abstract: A fluid distribution manifold for a vaporization cooled electrical apparatus. The manifold includes a flexible conduit of predetermined shape having a plurality of longitudinal and circumferential spaced apertures therein which distribute a vaporizable dielectric fluid uniformly and economically over the electrical apparatus.
