Abstract

276,003. Viel, E. A. O., and Amiot, J. Aug. 11, 1926, [Convention date]. Drawings to Specification. Regulating transformers.-Relates to methods of varying simultaneously the inductance of the primary and secondary windings of high-frequency transformers by means of movable conducting screens, and consists in making the screens of non-homogenous material, e.g., copper partially coated with tin or zinc, in order that the damping may be caused to vary according to a predetermined law.
