  • Patent number: 4039444
    Abstract: A device for the purification of water and methods for the use thereof are disclosed. The device comprises a closed container substantially porous to water, a purification agent contained therein and an ingredient dispersed in the purification agent for the purpose of inhibiting fine particles of the agent from escaping the container when the device is immersed in water. The disclosed inhibitory ingredients include certain modified starches, wood flour and aluminium lanolate soap.The device is especially useful in removing incipient impurities from drinking water that can elude customary water treatment and render drinking water organoleptically unsatisfactory.

  • Patent number: 4032465
    Abstract: Detergent compositions are prepared containing a carboxymethyloxysuccinate salt detergency builder by spray drying a slurry containing dispersed carboxymethyloxysuccinate salt and detergent compound, to which slurry an alkali metal silicate is added after the addition of the carboxymethyloxysuccinate salt, with the slurry water content being maintained at not less than 40% of the final slurry formulation and a slurry temperature of not less than 76.degree. C. This decreases the formation of insoluble lumps in the slurry and gives improved slurry viscosity control.
