Abstract: An aqueous fluorine-containing polymer dis­persion having particle diameters of 0.05-3 µm, which is obtainable by emulsion-polymerizing 5-95 parts by weight of a monomer mixture consisting of at least one monomer selected from the group consisting of alkyl acrylates whose alkyl groups have 1-18 carbon atoms and alkyl methacrylates whose alkyl groups have 1-18 carbon atoms and optionally an ethylenically unsaturated compound copolymerizable with the alkyl acrylates and the alkyl methacrylates, in an aqueous medium in the presence of 100 parts by weight of particles of a vinylidene fluoride polymer; and an aqueous dispersion containing a fluorine-containing polymer which consists essentially of 95-30 parts by weight (in terms of solids content) of said aqueous fluorine-containing polymer dispersion and 5-70 parts by weight (in terms of solids content) of an aqueous dispersion of a water-soluble resin and/or a water-dispersible resin. The aqueous fluorine-contain­ing polymer dispersion and the aqueous dispersion containing a fluorine-containing polymer have excellent heat resistance and weather resistance inherent in fluororesins and are significantly improved in film formability, transparency and adhesion to substrate. Therefore, these aqueous dispersions can be used as a coating composition for various applications, a fiber-­treating compound, a paper-processing compound or a floor-coating compound.

Abstract: Microfinishing devices and processes for in-process gauging of a microfinishing process of generally cylindrical workpieces. A size control shoe is used with a microfinishing shoe such that the diameter of a generally cylindrical workpiece can be continually monitored during the microfinishing process. Once a predetermined diameter or workpiece geometry is achieved, the machining process can be terminated. Several embodiments of size control shoes are disclosed which are particularly adapted for retrofit applications for existing microfinishing equipment. A "masterless" microfinishing machine is also described having arms which engage the size control and microfinishing shoes which follow the path of the workpiece during machining. Since the shoes must be maintained in engagement with the workpiece after a desired diameter is achieved, the pressure applied by the microfinishing arms is relieved until all of the workpiece surfaces are machined. Methods incorporating periodic reversing of the direction of rotation of the workpiece relative to the shoes are also described which provide enhanced material removal rate and high accuracy.
