摘要： This invention is a trough solar collector that uses the principles of high leverage in order to produce a lightweight, inexpensive thermal solar collector. The parabolic reflectors are held in proper shape by rigid ribs that are spaced apart along the length of the collector. The structure of the trough is held rigid by a unique sun-tracking system that not only guides a long trough row to point it toward the sun, but also maintains the whole length of the row in rigid configuration. Small-diameter cables are wrapped around a rotatable pipe that extends along the row. The cables extend around circular arches attached to the parabolic ribs that provide high leverage for rotating the troughs. Since the arches rotate in unison, the long trough row is maintained in rotational rigidity. Rather than having heavy concrete foundations and heavy structures to support the troughs, lightweight support posts are placed into the ground, and guy wires maintain the position of the posts.

摘要： A means is provided to produce fresh water from seawater on both the boiler side and the condenser side of an OTEC power plant. Part of the warm ocean surface water is evaporated, and its vapor transfers heat to the working-fluid boiler as the vapor condenses. The condensation of the vapor provides fresh water. On the condenser side, the condensation of the working-fluid vapor from the turbine in the condenser releases heat that evaporates seawater that runs down the outside of the condenser surfaces. The vapor from the seawater is condensed by a heat exchanger that uses input from colder seawater. As the cold seawater accepts heat from the condensing vapor, it becomes slightly warmer and provides the source of seawater that accepts heat from the condenser. The condensing vapor on the heat exchanger becomes fresh water that is drawn out as potable water. To provide additional fresh water, a multi-stage desalination unit uses the warm water discharge and the cold-water discharge from the OTEC plant to provide a temperature gradient that causes evaporation and condensation in each stage of the unit.

摘要： A motor, expander, compressor, or hydraulic device is formed with an oscillating rotating piston comprising a cylinder having an axis of rotation and end surfaces and defining an oscillating compression volume and an expansion volume. An axial sealing member separates the compression volume and the expansion volume, and seal members seal the end surfaces of the piston. Valves operate to close the compression volume and open the expansion volume at each oscillation of the piston. Means are provided for reversing the rotation of the cylinder at the end of a compression cycle of the piston. One or more pistons may be provided that contact other pistons along axial surfaces to form axial seal surfaces with rolling contacts that reduce friction energy losses.

摘要： The outstanding tensile strength of some materials are used in compression applications by using air pressure to supply the outward force on an enclosure and by using interior tension members to maintain the geometry of the air-pressurized structure. The air pressure on each face of the structure is balanced by the tension in the tension members. Due to the high modulus of the tension members, the air-pressurized structures are very rigid. It is the air pressure that actually supports any load placed on the structure, but it is the tension members that maintain the geometry when the load is removed, and the strength of the tension members determine how much air pressure can be sustained. The mass of tension material required in such a structure is roughly equivalent to the amount of filament material required in a cable to support the same load. The Compressed-air Rigid Building Blocks can be stacked like bricks to form strong, lightweight walls, buildings, towers, and other structures.

摘要： This invention is a trough solar collector that uses inexpensive aluminized plastic films as the reflecting surface. The films are held in proper shape by stretching them between rigid ribs that are spaced apart along the length of the collector. The structure of the trough is held rigid by a unique sun-tracking system that not only guides a whole of array of troughs on a field to point them toward the sun, but also maintains the whole length of each trough in rigid configuration. It is not necessary to extend rigid metal beams along the trough to maintain the rigidity of the trough. Small-diameter cables are wrapped around rotatable pipes that extend along the east and west sides of the field. The cables extend over the field of the troughs and are attached to connecting points above the troughs in such a way that when the rotatable pipes rotate, the cables move, the troughs move with them, and the cables provide the rigidity of the troughs. The troughs are supported by support posts that are driven into the ground. Since the support posts do not have to supply torque to rotate the troughs, no concrete foundations are necessary.

摘要： This invention has a series of multiple parallel plates that form desalination chambers between them that have seawater or other saline water flowing down the inside of one plate of each chamber. Steam which is generated by solar heat or other heat source condenses on the outside of first chamber of the series on the plate, which has seawater running down it. This releases heat that evaporates the seawater. The vapor flows to the other wall (plate) of the desalination chamber and condenses, and this releases heat that flows through the plate to the next stage of parallel plates and evaporates seawater flowing down the other side of the plate. Each succeeding stage operates at a lower temperature than the previous stage. The final stage is cooled by the evaporation of seawater into the air. One embodiment of the invention has the parallel plates sloped at an angle to the horizontal so that the seawater flows down on the lower plate and evaporates with heat supplied from below. The vapor condenses on the ceiling of the chamber. Since each succeeding stage upward is at a lower temperature, the vapor pressure will be lower in succeeding stages. This pressure differential can be used to pump the seawater from one stage to the next higher stage.

摘要： A unique arrangement for leg extension jumpers consists of elastic members connecting movable extension tubes to guide tubes located at the front and rear of a foot platform. The foot platform is pivotally connected at its front to the front guide tube or tubes and at its rear to a support tube or tubes fixed to and extending above the rear guide tube or tubes. A leg strap is fixed to the top of the support tube or tubes. In one modification, a brace member pivoted to and extending between the lower ends of the front and rear extension tubes acts as a ground engaging member. In another modification, the brace member is pivoted to and extends between the bottom of the front guide tube and support tube. The pivoted structure forms a pivoted parallelogram which is normally held in rectangular configuration by the elastic members.

摘要： To produce the most pleasing display of the color patterns, the colored light, which is produced by interference of light waves from the two surfaces of a thin liquid film, is separated from the principal beam of the incident light, magnified, and projected onto a screen. Reflection from the thin liquid film is specular reflection (angle of reflection equals angle of incidence). The position of the projection lens is determined by the position of the light source. Thin liquid films, such as soap bubbles, reflect colored light by interference of light waves which reflect from the front and back surfaces of the films. The color of the light is a function of the thickness of the film.

摘要： This invention is a water producer that extracts water from the air. One embodiment of the invention adiabatically compresses and heats the air. The heated air is cooled through a counter-flow heat exchanger so that it becomes supersaturated and water condenses. The air is then cooled further and passed back through the heat exchanger to recover its former heat. It then passes through an adiabatic expander to recover energy. A second embodiment utilizes a unique isothermal compressor/expander to compress the humid air isothermally so that the air becomes supersaturated with water, and the water condenses. The air is then cooled to remove the heat of condensation of the water and returned to the isothermal compressor/expander to recover energy. A third embodiment draws in humid air through a counter-flow heat exchanger to cool it down below its dew point so that water is collected. The air is then cooled adiabatically and passed back through the counter-flow heat exchanger and on to a compressor, which compresses the air back to ambient pressure and pushes the air out. These embodiments can be used to desalinate seawater, brackish water, or desiccant aqueous solutions by having a humidifier evaporate water from the liquids to make the input air to the water producer very humid.
