Abstract (en)
An insulating ribbon 10 coated on both faces within an electrically conductive paint is wound into a spiral coil on a core 11 and enclosed by a sheath 12. Spacers 13 are formed by insulating strips perpendicular to the turns of the coil whose ends are twisted through 90 DEG and welded to the margins of the ribbon. Electrical contacts to the two faces of the ribbon are formed by contact strip 22 on the core and contact strip 24 on the sheath (through its ends 23).
