摘要： A process for releasing leachable substances from a polymeric contact lens blank. the contact lens is confined in a cavity within a carrier to permit the hydration of the lens without permitting it to invert or roll over. A fluid flow is introduced into the cavity about the lens to extract leachable material from the lens. The process significantly reduces the amount of leaching fluid that is used and the amount of time that is needed for hydration, washing and extraction.

摘要： A method of coating on a melt contact surface such as that of an injection sleeve for casting, a plunger end face or a mold cavity comprises a step of charging the soot and the melt contact surface with opposite electrical polarities to thereby cause an electrodeposition of the charged soot on the melt contact surface. A preferred apparatus for the soot coating comprises means for producing an air stream surrounding a combustion gas stream including the soot and forming an air curtain for preventing the sprayed soot from scattering.

摘要： A nonaqueous resin dispersion in which particles of a low molecular weight polyolefin are finely and uniformly dispersed, which dispersion is obtained by the polymerization of a vinyl monomer (C) in the presence of 20 to 90% by weight of a substantially saturated polymer (A), based upon the total weight of the reactants (A), (B) and (C), and a low molecular weight polyolefin (B) dispersed finely therein. The resin dispersions of the present invention contain the low molecular weight polyolefin finely and uniformly dispersed such that it has an average particle diameter of not more than 10.mu. and preferably not more than 1.mu.. According to the Invention, the polyolefin is more finely and uniformly dispersed than previous dispersions produced by mechanical melt-dispersion of low molecular weight polyolefin and a resin.
