Abstract: A method for producing random form of nanosilicate platelets comprises mixing and acidifying an exfoliating agent with an inorganic acid to form an acidified exfoliating agent; intercalating layered inorganic silicate clay with the acidified exfoliating agent to form a mixture; and dissolving the mixture in a solvent and reacting it with a hydroxide or chloride of alkali metal or alkaline-earth metal. The hyperbranched polyamines serving as the exfoliating agent are prepared by polymerizing poly(oxypropylene)-triamine and diglycidyl ether of bisphenol-A (DGEBA). Hydrophilic amine groups of the exfoliating agent are acidified and then reacted with the layered inorganic silicate clay through cation exchange reaction and physical clay exfoliation to give random form of nanosilicate platelets.

Abstract: A lens activating device includes at least one elastic piece, at least one stationary piece and a movable piece. At least one elastic piece has at least four sheet portions and four sets of elastic portions. Each set of the elastic portions are serpentine and connected between two sheet portions in order to make the at least one elastic piece form a closed ring. The stationary piece is connected to two sheet portions, and the movable portion is connected to the other two sheet portions. The elastic force generated by the four sets of elastic portions exerts a restoring force on the movable piece. Via this arrangement, the slight rotation of the movable piece within the lens activating device can be reduced. Further, the problem that the elastic piece may scrape the neighboring elements can be prevented.

Abstract: A spring mounted tube pressing member for peristaltic pumps allows loading and unloading of an elastic tube section between the tube pressing member and a continuously revolving rotor assembly by selectively moving between a locked position for fluid transfer and an open position for unhindered mounting and demounting of the tube section or a replaceable tube cassette. Not only is the pressure on the tube pressing member adjustable by the spring used, its dynamic pressure distribution on the tube section also prolongs the tube flex life and reduces fluid back mixing and pulsation in the tube.
