Definitions

  • This invention relates to loaded GODClUC- tors, and more particularly to conductors of the kind commonly employed in telegraphy and telephony, in which the loading is provided in the form of a wire or tape of magnetic material wound uponthe conductor.
  • Such conductors are usually subjected to a processof annealing after having been wound with the wire or tape in order that the required magnetic propert'es may be developed in the loading material.
  • a method for the manufacture'ot loaded conductors which require heat treatment ed conductors which require heat treatment to develop the required magnetic properties which comprises laying a metal spacer 1/2000ths of an inch thick and fusible at a temperature not exceeding he temperature for annealing the loading upon the conductor, Winding the loading material over the conductor and the metal spacer and subjecting the loaded conductorto the said heat treat ment which causes the metal spacer to melt' 6.
