A method for purifying source water to obtain sterile, low-sodium water is described. The improved method employs ion-exchange, adsorption, filtration by particulate size, ultrafiltration, and reverse osmosis in combination with a closed holding system requiring only 2-3 ppm chlorine for sterilization. A method for storing treated water sterilized with chlorine, keeping the chlorine uniformly dist...

A posturepedic buoyancy device for supporting a person lying on said device in water or on land in a manner to minimize postural strain comprises an inflatable mattress having attached thereto an inflatable lumbar elevation cushion on the top surface of the mattress. The cushion elevates a person's lumbo-sacral region sufficiently to minimize hyper-extension in the lumbar region while lying prone ...

The angular timing relationship of the cams opening and closing the inlet and exhaust valves of an internal combustion engine can be varied while the engine is running to improve combustion efficiency. The angular relationship is varied by shifting of idler rollers 78, 80 acting on the camshaft driving timing chain adjusted by providing two cams 108, 110 for the same valve intake 104 so that cam 1...
