Abstract

927,387. Paper for electrolytic recording. MINNESOTA MINING & MANUFACTURING CO. March 30, 1961 [March 31, 1960], No. 11789/61. Drawings to Specification. Class 96. [Also in Group XIX] A light-insensitive facsimile recording sheet comprises a conductive backing having superimposed thereon a homogeneous coating of non- photoconductive indium oxide powder, and a binder having a lower electrical conductivity than the indium oxide. The backing may be metal foil, paper or fabric impregnated with conductive particles (e.g. aluminium flakes), vapour deposited metal film, conductive glass or conductive plastic. The coating comprises polystyrene, chlorinated rubber, rubber hydrochloride, or gelatine. In operation the sheet is wrapped round a rotating cylinder and a stylus contacts the sheet. Signals on the stylus produce corresponding degrees of current through the sheet and result in the liberation of free indium to provide a visible record of the current changes. An aqueous electrolyte, e.g. tap-water, is used, and this may be incorporated into the sheet, e.g. by providing a layer of gelatine. The indium metal image is erasible by oxidation, and sheets so erased can be re-used. A yellow light-absorbing dye may be incorporated to whiten the record sheet. Specification 927,386 is referred to.
