Abstract

251,239. Felten & Guilleaume Carlswork Akt.-Ges. April 22, 1925, [Convention date]. Addition to 222,436. Induction, preventing and minimizing. - In the method of reducing cross-talk in each section of a cable by altering the dielectric conditions between the conductors in a short length of the section, as described in the parent Specification, copper sleeves a open along a slit b are employed to embrace two conductors, and are compressed until the desired capacity is obtained between the conductors.
