摘要： Polyurethanes and polyesters are described which are the reaction products of an aromatic, aliphatic or cycloaliphatic diisocyanate, or of a diacid or diacid derivative respectively, with a diol containing a pendent UV-absorbing moiety, optionally also with one or more other diols or diamines. These UV-absorbing polycondensates can be applied to the surfaces of substrates by exhaustion methods or by spraying and act to protect polymers and dyes from degradation by UV radiation. They are therefore useful, either alone or in combination with other coating materials, for the treatment of wood, paper, textiles, leather or other surfaces which are exposed to degrading radiation.

摘要： An angular reflectance sensor having no moving parts and capable of the essentially simultaneous measurement of the reflectivity of a surface at a plurality of angles. The sensor comprises a quarter pitch graded index lens (78) having first end face (82) and second end face (84) and an optical axis (86). Light is coupled from an optical source (72) to an input position (88) on the first end face. A plurality of detectors are provided, each detector having associated therewith an output position (97-99) on the first end face. Each detector comprises a photodetector (74-76) and a fiber optic cable (94-96) for coupling light from the associated output position to the photodetector. The second end face of the lens is positioned adjacent a surface. Light reflected from the surface at a particular angle is focused by the lens to a particular output position, and thus to a particular photodetector.

摘要： An arrangement for optical multiplexing and demultiplexing. The multiplexer comprises an optical output waveguide and a plurality of optical input waveguides coupled to the output waveguide by nonblocking optical switches. An electrical activation signal at a switch causes light entering the switch through the associated input waveguide to appear on the output waveguide. The activation signals are provided by a pulse traveling down an electrode past the optical switches, such that parallel input signals on the input waveguides are time multiplexed onto the output waveguide to produce a serial output signal. A similar arrangement is provided for a demultiplexer comprising one input waveguide and a plurality of output waveguides.
