1,075,728. Portable solar stills for distilling sea water. AQUADOR PLASTICS, Inc. Aug. 25, 1965 [Sept. 21, 1964], No. 36510/65. Heading B1B. In a portable solar still for distilling sea water contamination of the distilled water with sea water is prevented by a separator ring 40, of minimum diameter greater than the maximum diameter of the evaporator surface 19, disposed adjacent the bottom of the evaporator surface so that sea water, even when the still is floating on rough seas, is thrown onto the sea water side 42 of the ring for passage through loose joint 45 into compartment 15, while distilled water which has condensed on the inner surface of flexible, heat transmitting bag 11 is deflected by surface 46 through openings 47 into a compartment 16. A sea water reservoir 60 is positioned at the top of the still, details illustrated on Fig. 2, not shown, a distributing surface 77 being positioned beneath the reservoir which is served with sea water through a feed hole which is kept free of scale by a pendulum device 82. Compartments 15 and 16 are defined by a conical separator member 13 and each have valved tubes 49, 17 for withdrawal of water. A ring shaped stabilizer tube 20 filled with sea water causes the bag to float with its conical upper section extending upwardly.
