  • Patent number: 10913829
    Abstract: In some aspects, the disclosure relates to processes involving a two-component resin system to provide a composite matrix binder. The first component may be a liquid reactive diluent, like an epoxidized vegetable oil, and the second component may be a solid, powdered polymer component, like a carboxylic functional acrylic or polyester, that may react with the liquid component. The liquid component may wet and coat the filler materials, while the powdered resin may soften/melt at higher temperatures below its threshold reactive temperature, thus allowing it to flow, diffuse and mix with the liquid component. This facilities processing and allows use of higher molecular weight resins and/or a higher Tg polymers without solvent use. When used in stone composite formulations with fillers like quartz and/or titanium dioxide, example resulting products have high hardness, very low water absorption, and high mechanical strength along with stain, chemical, and heat resistance.

Before a first server system 3a resumes service during the failure recovery, a second server system 3b sends the first server system 3a directory images of directories of a highest-level tier to a predetermined lower-level tier out of data of files stored in a second storage apparatus 10b, and the first server system 3a restores the directory images in a first storage apparatus 10a. When the request is transmitted from the first server system 3a, the second server system 3b reads an additional directory image from the second storage apparatus 10b and transmits the additional directory image to the first server system 3a.
