Abstract

215,504. Roberts, V. S. March 14, 1923. Inductances.-A tapped coil is wound from a single length of wire on a hollow former a by forming loops d in the wire and passing them through holes c in the former. The loops are led away through the interior of the former and are preferably led out again through perorations e at one end.
