Abstract: A method of forming metal spheres includes ejecting a precisely measured droplet of molten metal from a molten metal mass, buffering the molten metal droplet to reduce the internal kinetic energy of the droplet without solidifying the droplet and cooling the buffered droplet until the droplet solidifies in the form of a metal sphere. An apparatus for fabricating metal spheres includes a droplet generator that generates a droplet from a molten metal mass, a buffering chamber that receives the droplet from the droplet generator, and diminishes internal kinetic energy of the droplet without solidifying the droplet, and a cooling drum that receives the droplet from the buffering chamber, and cools the droplet to the extent that the droplet solidifies into a metal sphere. The apparatus may further include a collector arrangement that receives the metal spheres from the cooling drum and makes the metal sphere available for collection.

Abstract: A jack and plug assembly wherein the jack has downwardly extending inner and outer coaxial connectors, and is designed to receive a coaxial cable at a right angle to the axis of the jack, with the inner connector of a coaxial cable attached to the inner conductor. The inner connector of the jack comprises a downwardly extending hollow cylindrical spring metal conductor, with the upper portion of the conductor having a surface hole of a size slightly smaller than the diameter of the inner conductor of the coaxial cable to be connected thereto. A lower portion of the hollow cylinder below the hole is removed and the surface of the hollow cylinder between the top and the lower portion is slotted to permit forcible expansion of the upper portion so that the hole is enlarged sufficiently to receive the larger inner conductor of the coaxial cable.
