Abstract: In a cleaning, scouring, scrubbing and/or polishing pad of the type formed from a pliable, flexible foam plastic body having a scrubbing surface with a plurality of protuberances being defined by peripheral surfaces generally perpendicular to and forming generally sharp edges with an upper scrubbing surface of the protuberances, there is provided an improvement which includes a hardened flexible, elastic material, generally more rigid than the foamed plastic material forming the pad, and impregnated into the foamed plastic at the protuberances to a depth of at least the height of the protuberances.

Abstract: A pourable solid filter material for the removal of foreign gases, particularly unpleasant odors, from the air comprises a granular composition. The granular composition is a mixture of at least one acid or basic chemosorptive substance which reacts chemically with the foreign gas, and a substance which stores moisture. A binder which binds the chemosorptive substance into the form of granules is preferably also used as the moisture storing substance. The granules may consist of spherical particles between 0.5 to 5 mm. in diameter. Suitable acid chemosorpents include organic carboxylic acids, amidosulphonic acid, p-toluene sulphonic acid, boric acid, sodium, potassium and ammonium hydrogen sulphates and phthalic andydride. Preferred basic chemosorbents include sodium and potassium carbonates, oxides or hydroxides of calcium and barium, sodium metasilicate, lithium carbonate, hydroxides of sodium or potassium, cement, and potash, double, and soda water glass.

Abstract: In a cleaning, scrubbing or polishing pad of the type formed from a pliable, flexible foamed plastic body having a scrubbing surface, the improvement of a plurality of protuberances on the scrubbing surface, each of the protuberances being defined by peripheral surfaces generally perpendicular to and forming generally sharp edges with an upper scrubbing surface of the protuberance.
