Alternatively where a bi-polar or quadripolar synchronous motor having permanent magnets is used to drive the roller a D. C. source is arranged to energize a selected one of the three-phase windings when it is disconnected from the supply. The resultant magnetic field acts with the field from the poles of the rotor to move it to a predetermined rest position with the poles of the roller situated opposite permanently stationary poles of opposite polarity.

Patent GB-763740-A (GB)
Abstract: 763,740. Capacitors. STANDARD TELEPHONES & CABLES, Ltd. May 6,1955 [May 11, 1954], No. 13712/54. Class 37. In the manufacture of capacitors comprising a metal electrode coated with a dielectric material, a high-voltage stress is applied across the dielectric material in order to cause it to break down at any weak spots and expose the metal, the exposed metal being subsequently removed by an electrolytic or chemical etching process. The high-voltage stress is preferably pulsed so that the mean current flowing through the weak spots in the dielectric is small and overheating does not occur. The metal foil 1, coated on both sides with dielectric material, is passed through an electrolytic bath 4 and is connected through a switch 12 to one side of a capacitor 9, the other side of which is connected to plates 6, 7 disposed on opposite sides of the coated foil 1 as it passes through the bath 4. A D.C. charging voltage is applied at points 10, 11 so that on closing the switch 12, the potential difference across the capacitor 9 is applied between the plates 6, 7 and the metal foil 1 through the electrolyte and the dielectric coating on the foil. Alternative pulse sources, e.g. thyratron circuits, may be used. In a modification, the electrodes 6, 7 are replaced by conducting rollers which are in contact with the coated surface of the foil and serve to guide it through the electrolytic bath.
