Abstract: Enhanced visual acuity is provided by one or more exceptionally narrowband absorption dyes having sharp turn-on and cut-off slopes selected to spectrally sculpt light to correct most types of colorblindness, to exaggerate color contrast vision for everyone, and/or to markedly sharpen visual focus beyond normal vision. The dyes are incorporated, for example, in sunglasses, prescription and non-prescription eyewear, window thin films and artificial light sources such as incandescent, fluorescent, and LED lightbulbs to provide improved photopic color vision, improved mesopic dim light color vision, and also sharper scotopic night vision.

Abstract: High-temperature solar trap collectors provide near ambient temperature solar entry surfaces and negligible thermal radiation losses by counterflowing low velocity transparent gases or liquids (fluids) to nullify internal thermal diffusion and radiative heat losses at the solar entry surface. Small steradian (sr) baffling plus wavelength-selective materials trap the entire 0.35 u to 2.7 u incoming solar spectrum and heat highly absorbing internal surfaces to high temperatures; only a small solid angle of the 2? steradians—on the order of 0.01 sr—of internal thermal radiation escapes. A nearly 100% efficient flat panel solar trapping embodiment exhibits alpha (?) absorption nearing 1.0 and radiant emission losses nearing 0.0 even at solar collection temperatures in excess of 1,000° K. Ultra high collection efficiency counterflow configurations are ideal for solar hot water, space heating, cooling, energy storage, and electric power generation applications.

Abstract: The present invention proposes a permanent and prosperous solution to both human global warming (˜0.26 to 0.74° F.) as well as natural global warming (˜7 to 9° F.). It simultan-eously employs all three of the physical laws to thermostatically regulate Earth: Macro solar energy reflection; sequestration of absorbed solar energy; and, enhanced infrared radiation from Earth. Temporal and spatial macro aerosol water evaporation is employed to triple-cool Earth's surface, by way of: 1. Low-altitude atmospheric and oceanic vapor-cooling and/or macro storage of artificial snow; 2. Automatic ascension of lightweight water vapors to high-altitudes for enhanced water-phase-change infrared radiation from Earth, and; 3. Increased cloud coverage to reflect more incoming solar energy.

Abstract: An excavationless geothermal system for heating and cooling applications includes a potable water storage container that receives water from a water supply through a supply line and a reversible water meter. The water in the storage container is circulated through a heat pump, and when the temperature of the water in the container is increased or decreased by the heat pump, the water is returned to the supply through the reversible meter.

Abstract: A di-lubricant for shaving comprises a low concentration of polyacrylamides suspended in water to provide lubrication for skin but not for hair.

Abstract: A safety lens liner adapted to be mounted on the peripheral edge of an eyeglass lens is disclosed. The liner is shaped to engage a groove on the rim of an eyeglass frame to secure the lens in place. The lens incorporates a circumferential groove on its peripheral edge, which receives a tongue extending inwardly from the inner surface of said tongue, for positioning the tongue on the peripheral edge of the bead.

Abstract: A method of producing multifocal ophthalmic lenses having a near vision minor lens element adhesively secured to the ocular surface of a major lens is disclosed. The ocular surface of the major lens is finished to provide an ophthalmic prescription lens. This ocular surface may have a spherical, cylindrical, or prismatic curvature, or any combination thereof, and thus generally may have a complex toric curvature. The minor lens has a predetermined "add power", to provide a near vision segment on the major lens, and preferably is flexible, or is made flexible as by heating, so that it can conform to the shape of the toric curve on the ocular surface of the major lens without distortion or change in its add power. An adhesive material is placed on the major lens, and the minor lens is carefully positioned and gently pressed against it so that it conforms to the curvature of the major lens.

Abstract: A method and apparatus for manufacturing prescription eyeglass lenses through the assembly of modular lens components is disclosed. The lens components include single-vision spherocylindrical stock lenses having positive or negative power, prism wedges which have no spherical or cylindrical power, bifocal or multifocal lens buttons, and slab-off prism wedges. These components may be assembled in accordance with data provided by a central computer to produce a desired prescription lens. The components are precisely aligned by means of an assembler, and are laminated by suitable adhesives.

Abstract: A composite glass/plastic ophthalmic lens is disclosed. The lens consists of a thin layer of glass, preferably photochromic, adhered to the front of a plastic layer, by a highly elastic adhesive. The rear surface of the glass has a different radius than the front surface of the plastic so that the space between the lenses forms a tapered gap which is filled by the elastic adhesive. The edge thickness of the elastic adhesive is sufficient to insure that the increase in diameter of the plastic layer with respect to the diameter of the glass layer due to differences in the thermal expansion characteristic of the glass and the plastic will not damage the composite lens even over a temperature range greater than 300.degree.
