    摘要： Hydrated sodium silicate particles can be expanded by heat to form thin-walled bubbles that can be broken, neutralized, washed and dried to provide hydrated silica flakes. These flakes can be mixed with non-swelling sorptive particles such as TLC grade silica and used to make chromatographic articles. One such article is a composite of a poly(tetrafluoroethylene) fibril matrix in which those particles and hydrated or fired silica flakes are enmeshed. The hydrated silica flakes can be fired to a refractory state and then incorporated into protective coatings to enhance their resistance to abrasion while also better protecting the coated substrates from corrosion.

    摘要翻译： 水合硅酸钠颗粒可以通过加热来膨胀以形成可以破碎，中和，洗涤和干燥以提供水合二氧化硅薄片的薄壁气泡。 这些薄片可与非溶胀吸附颗粒如TLC级二氧化硅混合并用于制备色谱制品。 一种这样的制品是聚（四氟乙烯）原纤基质的复合材料，其中这些颗粒和水合或煅烧的二氧化硅薄片是啮合的。 水合二氧化硅薄片可以烧制到耐火状态，然后加入到保护涂层中，以增强其耐磨性，同时还能更好地保护涂覆的基材免受腐蚀。

    摘要： Glitter, at least a portion of which comprises color shifting film. The glitter is useful in any of a variety of ways, including in loose form, attached to the surface of a substrate, in a dispersible combination, or present in a matrix material ranging, for example, from liquids, such as water and alcohols, to gels, such as silicone and glycerol, to hard, rigid materials such as plastics, particle board, and fiberglass. Examples of other matrix materials include putties or molding clays, rubbers, and adhesives.

    摘要： Game with a privacy member. The game includes a play region and a directional viewing screen. The directional viewing screen covers at least a portion of the play region such that said portion of the play region is viewable therethrough at a first player position, but is not viewable therethrough at a second player position. The game with privacy member in accordance with the present invention allows for enhancement of existing games, as well as for the creation of new games or new play patterns of existing games.
