    摘要: The present invention relates to novel bondable trisaryl-1,3,5-triazines containing active (acidic) hydrocarbons and the use thereof as an ultraviolet light absorber. The presently claimed compounds are particularly useful, either alone or in combination with other additives, including other ultraviolet light absorbers and stabilizers, in stabilizing polymers and other materials from degradation by environmental forces such as actinic radiation (ultraviolet light), oxidation, moisture, atmospheric pollutants and combinations thereof.

    摘要: Accumulating measuring devices which indicate the flow of electric current on graduated scale. Current flow may be of any fixed rate or value, steady or pulse, and scale may be any desired graduations. Current flow is indicated by a persistent electrochromic display material which changes color due to passage of electric current through it. The entire device is electronic, with no mechanical parts. Other accumulating functions may also be measured with the device if they can be converted first to electric current. One particular application is an elapsed time indicator, e.g. a watch or clock.
