Noninductive twisted-wire resistor

Claim 1

A noninductive resistor comprising a supply line having an electrical terminal at its one end; a return line having an electrical terminal at its one end; said ends being adjacently located with respect to each other; each of said supply and return lines respectively having ends remote from said terminal ends, said remote ends being integrally and electrically connected together; said supply and return lines being equally dimensioned and extending from said remote ends to said terminal ends twisted together in spaced abutting relation to provide the same twist pitch for each said supply and return line; said twisted-together supply and return lines having said abutting relation at spaced areas to provide direct contact between said lines thereat, and a cross-sectional plane through said areas being absent of any central open area; said supply and return lines having an insulating coating thereon with part of said coating removed to provide an exposed area on said lines; means having relative movement with respect to said exposed area to provide a resistance adjustment of the resistor; and said twisted lines being wound in toroidal form about a base element.
