    Abstract: Non-woven fibrous material is manufactured from a foamed fibre dispersion fed to a foraminous support and the invention resides in forming the foamed fibre dispersion by applying a vacuum to the underside of the support to recover a major part of the liquid from the dispersion on the support, delivering the recovered liquid to a mixer and mixing the recovered liquid in the mixer with fibres, a air, and a surface active agent to obtain a mixture thereof which is fed to a foaming device in which the foamed fibre dispersion is formed for feeding to the support.

    Abstract: An electrically conductive base paper has on one side thereof a continuous coating of dielectric material consisting of a polymeric material deposited from an aqueous dispersion having a minimum film-forming temperature not greater than 30*C to provide an intense image with no background discolouration due to pick-up of excess toner material during processing. If desired two such coatings may be used of which each has a minimum film-forming temperature not greater than 30*C or the second of which has a minimum film-forming temperature of between 60*C and 120*C. The coating may contain an inorganic pigment material in an amount of up to about 20 percent by weight of dry polymeric material used.

    Abstract: A colour reactant component for coating a receptor sheet of the kind used in copying paper systems is produced by incorporating in an aqueous slurry of an inorganic mineral at least one soluble salt of the metals cobalt, cerium, copper, iron, manganese, lead, indium, lanthanum, barium, antimony, beryllium, strontium, nickel, zinc, calcium cadmium, magnesium, chromium, and tin, and at least one soluble aluminate salt, so as to precipitate at least one insoluble aluminate compound in the slurry, and thereafter incorporating a binding agent selected to bond the colour reactant component to the receptor sheet.

    Abstract: In copying paper for use in a pressure-sensitive copying system of the kind in which copying is effected by reacting together a colour-former and a colour-reactant, the colour-reactant is formed by fine particles of oil-absorptive, inorganic, mineral material, the particles being individually coated, at least in part, with an organic, acidic, oil-soluble polymer containing uncombined phenolic hydroxyl groups, said polymer being reactive with the colour-former to develop it to the coloured form. The polymer may be a phenol/formaldehyde or a phenol/acetylene polymer and the mineral particles may consist of silicates, alumino-silicates, silica, alumina or silica/alumina mixtures. In one example they are kaolin.

    Abstract: Improvements are afforded in method and apparatus for making non-woven fibrous webs including paper from a foamed aqueous furnish containing a surfactant in that the foam acquires and has imparted thereto physical characteristics as regards attainment of such a highly emulsified state that the bubbles are scarcely visible to the naked eye, as regards viscosity build-up of the foam to at least 22 seconds as measured with a Ford Cup Type B-4 and as regards the specific gravity being no greater than 0.35. Other improvements pertain to vortical mixing in the production of the foam, to combining the method and apparatus with conventional methods and apparatus and to handling the surfactant-containing water when in the foamed furnish and likewise as drained from the formed web.
