Abstract: A non-segregating, free-flowing bath bead composition, based on prilled urea in combination with active bath components, is produced by admixing urea prills with an oily liquid emollient to distribute the emollient substantially uniformly on the prills and then adhering a powdered surfactant to the emollient-bearing prills to produce free-flowing bath beads. If desired, color can be imparted to the prills by providing moisture-containing prills and commingling the prills with a powdered, water-soluble dye prior to the distribution of the emollient thereon.

Abstract: Automotive exhaust gases, and especially the exhaust gases which have been further oxidized by a treatment in a catalytic converter, are treated by passing them through a filter containing paper coated with a calcium carbonate coating. The paper is desirably coated on both sides with heavy coatings and wound into a roll with spacers extending through the roll to permit the gases to pass therethrough. The calcium carbonate desirably constitutes at least 85% of the weight of pigments and fillers in the coating and the proportion of binder does not exceed 20% of the total weight of pigments and fillers. The acidic gases in the exhaust, and particularly the oxides of sulfur, react with the finely divided particles of calcium carbonate in the coating to form an ash which flakes off from the lower face of the roll while the gases pass upwardly through the roll.
