Abstract: A process for preparing radioactive and other hazardous liquid wastes for treatment by the method of vitrification or melting is provided for.

Abstract: A liquid emulsion membrane process for removing sulfate anions from waste water is disclosed. The liquid emulsion membrane process includes the steps of: (a) providing a liquid emulsion formed from an aqueous strip solution and an organic phase that contains an extractant capable of removing sulfate anions from waste water; (b) dispersing the liquid emulsion in globule form into a quantity of waste water containing sulfate anions to allow the organic phase in each globule of the emulsion to extract and absorb sulfate anions from the waste water and (c) separating the emulsion including its organic phase and absorbed sulfate anions from the waste water to provide waste water containing substantially no sulfate anions.

Abstract: A continuous band of impervious elastic material covers and seals the closure around the periphery of a piece of luggage or similar container. An opening is provided, where necessary, through which the luggage handle protrudes. Various cross-sectional shapes are described for achieving close-fitting conformity with the peripheral side surfaces of the luggage.
