Abstract: In a process for removing amines having normal boiling points under 100.degree. C., present in an oxygen-containing gas, which comprises passing the amine-containing gas through activated carbon and releasing the gas into the atmosphere, said gas containing from about 5 ppm by volume to about 5,000 ppm by volume of amines, the improvement which comprises adding about 500 ppm to about 30,000 ppm by volume of gaseous carbon dioxide to said gas prior to passing the gas through the activated carbon.
Abstract: In a process for removing hydrogen sulfide from an oxygen-containing gas stream by passing said gas stream through activated carbon, said stream containing from about 5 ppm to about 10,000 ppm by volume, which comprises adding ammonia to said stream prior to its passage through the carbon, improvement in which the amount of added ammonia is such that its concentration will be at least equal to the concentration of the hydrogen sulfide and not greater than 10,000 ppm with the proviso that when the concentration of hydrogen sulfide exceeds 4,000 ppm by volume, the concentration of the ammonia will not be greater than 6,000 ppm by volume.
Abstract: A hypodermic syringe capable of pre-filling aseptically from either end. Both ends of the rimmed syringe barrel are sealed and capped with standard vaccine or syringe vial closures and crimped aluminum seals. Both ends of the pre-filled and sealed syringe maintain assured sterility integrity by guaranteed microbe-proof barriers during the entire shelf life of package or container. The syringe is prepared for use by simply removing protective caps or seals. The needle assembly is packaged separately and placed in position on syringe by a simple action.
Abstract: A pre-filled syringe-needle assembly in which the needle is covered with a shield-closure unit to assure sterility. Said shield-closure unit comprises a tube which covers the needle and a plug for said tube, one end of said tube being adapted for fitting tightly over the reduced part of the barrel of a syringe, and the other end being covered by the plug, both said end and plug covering it being adapted to provide an air-tight fit between them, said plug being sufficiently long to engage the tip of the needle inside the tube.
Abstract: Migration of suspended materials in nail enamels is prevented by the addition thereto of from about 0.10 to 5.0% by weight of a phosphatide such as lecithin. Settling and migration of suspended materials in nail enamels is prevented by the addition thereto of from 0.10 to 5.0% by weight of a phosphatide such as lecithin and from about 0.04 to 0.20% by weight of a cosmetically acceptable acid.
