Filed: 1930-11-17
Abstract: 364,756. Re covering clean pulp from old paper. WEBER, R., Drentwede, Bremen, Germany. Nov. 17, 1930, No. 34557. Convention date, Nov. 18, 1929. [Class 96.] Clean paper pulp is recovered from old printed paper by a cold process by treating with causticizing sludge, obtained as a waste product in the causticizing of soda, the pulp then being washed ; carnallite waste iquors may be added to the causticizing sludge, and the causticizing sludge or the carnallite liquor may be prepared from its constituents. The sludge may be obtained in the causticizing of pure sodium carbonate or in the causticizing of the residue obtained by evaporating and igniting the boiling liquors used in the manufacture of soda pulp or sulphate pulp. When carnallite waste liquor is added, magnesium hydroxide is formed, the colloidal nature of which assists removal of the printer's ink. In an example, 1000 kg. of old printed paper is disintegrated in a Hollander and 300-500 litres causticizing sludge added. After 1-2 hours the pulp is washed, preferably by means of a washing drum which revolves in the pulp and is covered with a fine sieve.

It is combined in Fig. 2 with a transparent conductive film 36, an electroluminescent-dielectric layer 38 and a current diffusing layer 40 to form a light amplifier. The current diffusing layer 40, which may be omitted, may comprise cadmium sulphide made conducting by adding cadmium chloride and heating to 700‹C. for 20 minutes. It has a high impedance parallel to its main surfaces but it need not have a linear impedance characteristic. An opaque layer 46 may be included, e.g. of black lacquer or of carbon particles mixed with a plastic. The cell in Fig. 4 comprises a conductive support plate 28 and an apertured electrode 52 spaced therefrom by separators 50 with a layer of photo-conductive material between them formed by squeegeeing a mixture of crystalline cadmium sulphide powder and ethyl cellulose across the mesh to fill the interstices. When the solvent evaporates, the binder-powder mix contracts to form depressions. It may be combined with an electroluminescent layer in a light amplifier as before, Fig. 5, (not shown). In another modification tiny particles, fibres or beads of glass or plastic are contained in the photo-conductive layer; or the layer itself may simply be formed with holes formed by spraying the photo-conductive powder with a plastic binder and a quick drying solvent so that the sprayed particles dry as soon as they land on the support plate, or by mixing with polystyrene foam and forming gas or air bubbles in the solidifying layer. Silk screen printing may also be used to print a pattern of dot arrays of photo-conductive material such as pillars of material separated by air spaces, Fig. 8 (not shown). In each case the photo-conductive layer assembly may be combined with an electroluminescent layer to give light amplification. The photo-conductive material may be cadmium sulphide or selenide or lead sulphide in dry power form or mixed with ethyl cellulose, methyl methacrylate or polystyrene. The electroluminescent material is zinc sulphide/copper mixed with ethyl cellulose.
