    摘要: A passive collimating tubular skylight consisting of a radiant energy-collecting aperture, a radiant energy-delivering aperture, and a radiant energy passageway between these two apertures, the passageway having a specularly reflective interior surface and a configuration to improve the collimation of the radiant energy passing therethrough. The skylight can be configured with the radiant energy-collecting aperture located above the roof of a building, oriented to collect sunlight; and equipped with a sealed weatherproof glazing, with the radiant energy-delivering aperture, or luminaire, located at ceiling level within the building, and equipped with a diffusing glazing; and with the reflective tubular light passageway constructed with a larger cross sectional area near the radiant energy-delivering aperture than near the radiant energy-collecting aperture. In complete accord with the second law of thermodynamics, and as proven by experimental results, the new passive collimating tubular skylight provides significant advantages over the prior art, including better solar energy collection, higher throughput optical efficiency, improved radiant energy collimation, enhanced interior illumination levels, and more precise positional control of the interior illumination.

    摘要: A reflective article has a multilayer film covering a patterned retroreflective layer. In one embodiment the patterned retroreflective layer includes a separate indicia layer covering a retroreflective substrate. The indicia are substantially hidden under normal viewing conditions but easily detectable under retroreflective lighting conditions. Various types of retroreflective layers are disclosed. The article can also include microstructured relief patterns which produce holographic images under ambient lighting but which disappear under retroreflective conditions. The multilayer film includes alternating layers of at least a first and second polymer, and has a relatively high reflectivity for normally incident light within a first spectral range which is approximately coextensive with the visible spectrum, and a relatively low reflectance for normally incident light within a second spectral range. The second spectral range can include a transmission window of 15% or less fractional bandwidth located at least partially in the visible spectrum. Film constructions are disclosed which achieve sharper spectral transitions than previously attainable. Film constructions are also disclosed which preserve such sharp transitions even at high entrance (tilt) angles.

    摘要: A refrigerator interior liner can be made of a composition including a monovinylaromatic polymer matrix having an average molecular weight in weight Mw above 150,000 g/mol; rubber particles; and low- Mw plasticizers. The rubber particles can have an RPS volume of about 8.5 μm, a monomodal distribution, a swell index above 13.8, and an RPVF of at least 39%. The composition can be prepared by forming a polymerizable mixture including a monovinylaromatic monomer, and dissolving a viscous rubber in the polymerizable mixture. A free radical initiator and a chain transfer agent can be contacted with the polymerizable mixture at conditions whereby phase inversion subsequently occurs. The chain transfer agent can produce an increase of the rubber to PS phase viscosity ratio within the inversion reactor. Polymerization can be continued until a monovinylaromatic polymer matrix having rubber particles dispersed therein is obtained.
