  • Patent number: 8492448
    Abstract: Systems and methods for performing photoreactions in a photoreactive material using scattered actinic light from at least one light-diffusing optical fiber are disclosed. The systems and methods include disposing a light-diffusing optical fiber relative to the photoreactive material. The light-diffusing optical fiber has a glass core, a surrounding cladding, and nano-sized structures situated either within the glass core or at the core-cladding boundary. The nano-sized structures are configured to scatter guided actinic light that travels in the light-diffusing optical fiber from an actinic light source. The scattered actinic light is provided throughout the photoreactive material and causes a photoreaction throughout the photoreactive material.

  • Publication number: 20020169221
    Abstract: The disclosed process to obtain a modifier for cement systems comprises a synthesis of the modifier by a process of polymerization in a soft alkaline catalysis. This contributes to the formation of a product with a low molecular mass and viscosity. The concentration of the homogeneous aqueous solution is from 40-58% and the specific production of the process is Q=0.25 to 3.00 kg per hour in comparison with the specific production of the known prototype which is Q=0.03 to 0.04 kg per hour. One of the most important characteristics of the new process used to obtain the disclosed modifier is the fact that synthesis is achieved without external heat sources. Also, synthesis is achieved either by a periodic process or a continuous process.
