摘要： A NONBURNING PAPER WHICH IS SUITABLE FOR PRINTING, WRITING, ETC IS DISCLOSED. THE BASIC INGREDIENTS OF THE NONBURNING PAPER ARE ASBESTOS, FIBER GLASS, A LIGHT METAL VERMICULITE AND A LATEX RESIN. THE METHOD OF PRODUCING THIS NONBURNING PAPER, WHILE WHICH EXTINGUISH ITSELF IN PURE OXYGEN, IS AS FOLLOWS; AN ACIDIFIED AQUEOUS SOLUTION OF FLOCCULATING AGENTS IS PREPARED; FIBER GLASS IS ADDED AND ADMIXED TO THE ACIDIFIED SOLUTION TO PREPARE A DISPERSION; ASBESTOS IS ADMIXED WITH THE FIBER GLASS DISPERSION; A LATEX RESIN IS ADMIXED WITH THE DISPERSION; A LITHIUM VERMICULITE SUSPENSION IS ADDED TO THE DISPERSION; SUFFICIENT AMMONIUM HYDROXED IS ADDED TO THE DISPERSION TO NEUTRALIZE THE ACID PRESENT AND TO FORM AMMONIUM SULFATE WHICH ACTS AS A CATALYST FOR CURING THE LATEX RESIN; THE RESULTANT DISPERSION IS FILTERED; AND THE FILTRATE IS REMOVED, ROLLED AND DRIED. THE RESULTANT SHEET OF PATER IS NONBURNING AND, IN THOSE CASES WHERE ITS PREPARATING IS SO TAILORED, IT CAN BE USED AS WRITING PAPER OR CAN BE USED IN A CONVENTIONAL PRINTING PRESS, SUCH AS, AN OFFSET LITHOGRAPHIC PRINTING PRESS.

摘要： (1) ASBESTOS ARTICLES OF IMPROVED DIELECTRIC STRENGTH ARE MADE BY DISTRIBUTING PULVERULENT EXFOLIATED VERMICULITE THROUGHOUT AN ASBESTOS FIBER-BINDER COMPOSITION; APPROXIMATELY 1 PART OF VERIMCULITE IS PRESENT PER 1-5 PARTS OF ASBESTOS. (2) A MATERIAL OF GREAT DIELECTRIC STRENGTH IS MADE BY WETTING THE ORDINARY SHEET OF THE ABOVE COMPOSITION WITH WATER SOLUTIONS OF ALUMINUM PHOSPHATE OR CERTAIN SILICO FLUORIDES, PRESSING THE WET SHEET AT ELEVATED PRESSURE FOR A TIME TO INCREASE THE DENSITY THEREOF AND, THEN DRYING THE WET, PRESSED ARTICLE.
