Abstract: The aim of the invention was to find a method of producing a sorptive body, to be used especially with objectives such as the elimination of odors and air freshening. In the invented process a granular or powdered solid component consisting of a sorptive material, e.g. active carbon, or a compound containing such a material, is mixed with a binding agent, by which it is generally fixed to a carrier substance. The essence of the invention is that at least part of the finely-ground solid component is mixed with a liquid sorbate; only then it is combined with the dissolved binding agent. In a subsequent operation heat is applied to the mixture, thereby expelling the sorbate. The heat causes pores and capillaries to form within the binding agent, thus enabling air to enter into the sorptive substances deposited in the binding agent and so effecting an increase in the active area of the surface of the body.

Abstract: Sustained release compositions containing depots of active substances such as soaps, detergents, antimicrobial agents and the like dispersed in a flexible carrier which are slowly released during use.

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.
