Purifier of Sea Water Invented for Men Adrift PASADENA, CALIF. Sailors or airmen adrift on the ocean can now survive as long as 25 days on sea water purified through a simple chemical formula, Dr. Alex Goetz, of the California Institute of Technology,' Tech-nology,' said recently. Dr. Goetz said that he had perfected per-fected the chemical after a year of intensive research. Although the process is a military secret, he described de-scribed the chemical as a combination combina-tion of collodial materials. "It's as simple as pouring water from one sea boot to another," he said. Two containers are necessary. One is used for precipitating poisonous materials from the salt water. About two hours later the sea water, except that containing the precipitate, is poured into the other container, where it is further clarified and ready to drink. A waterproof container about the size of a package of cigarettes would hold enough to purify approximately I two quarts of water, he said.
