Abstract: A solar powered water pump combines an evacuated tubular solar collector array for heating air with a diaphragm type pump by providing an internal heat exchanger in the manifold of the collector array. The heat exchanger uses heat from the heated air to generate steam from water. The steam from the heat exchanger is used to drive the diaphragm pump. Another heat exchange medium such as freon or ammonia can be used in place of water.

Abstract: In a preferred embodiment, a pressurized portable elastic membrane liquid container having an expandable circular elastic membrane of which a central location thereof has an integrally molded handle extending upwardly and a boss of increased thickness of the membrane extending downwardly from a bottom face of the membrane from beneath the handle, with the boss extending radially outwardly from said central location for a distance of about one-half radius of the circular elastic membrane, and with an additional boss in the form of a circular ridge extending upwardly from a top surface of the membrane with the ridge extending above a plurality of mold injection points located in juxtaposition to an outer periphery of said circular elastic membrane, the membrane being of polyisopreme base rubber and including an ozone inhibitor.

Abstract: A hose-mounted faucet-connector having an integral inner and outer housing, the outer housing at one end being connectable to a hose and at the mounting end having the inner housing integrally mounted across the remaining other mounting end sealably thereof except for a mounting aperture centrally within the body of the inner housing that extends concavely within space of the outer housing, the inner walls of the outer housing including spaced-apart ribs extending substantially axially of tubular space from the one end to the integral inner housing at the mounting end of the outer housing; in a preferred embodiment, the faucet mount is mounted on a valve-containing hose that is mounted on an inlet-outlet structure of the pressurizable vessel.
