    摘要： New polyhydric phenol coesters are disclosed of polyhydric phenols, having 2 to 3 phenolic hydroxyl groups and 1 to 3 benzenoid rings, with carbonic acid and an inorganic acid which can be phosphorous acid, phosphoric acid, and boric acid. The new coesters have molecular weights from 700 to about 10,000, preferably from 1200 to 7000, and are highly effective stabilizers for a variety of synthetic resins.Stabilizer compositions comprising a polyhydric phenol coester and a known polymer stabilizer, as well as synthetic resins stabilized with such stabilizer compositions, are also disclosed.

    摘要： An information display device includes a two-dimensional array of cells, each cell including an opaque wall pierced by an aperture and containing an opaque ferromagnetic spherical shutter member movable by electromagnetic means to roll upon a vertical wall of the cell between limiting positions in which it respectively exposes and occults the aperture. The shutter members may be restrained in their limiting positions by friction or magnets embedded in the cell walls.
