    摘要： A top entry ball valve including a valve body, a valve cover, a valve stem, an assembly screw, a spring, a support sleeve, a support valve seat, a sphere, and a sealing valve seat. The valve stem passes through the valve cover and the valve body and is fixedly connected to the sphere disposed within the valve body; the valve cover is fixed to the opening of the cavity of the valve body by screws, to seal the cavity of the valve body; the sphere spherically fits with the support valve seat and the sealing valve seat; the support sleeve and the spring are provided between the support valve seat and the valve body; the spring presses the support sleeve and the support valve seat such that the support valve seat clings to the sphere; the support sleeve is fixedly connected to the valve body by the assembly screw.

    摘要： The present invention provides a water-soluble crosslinkable poly(oxyalkylene)-containing prepolymer. The crosslinkable poly(oxyalkylene)-containing copolymer prepolymer of the invention is prepared by reacting an amine-capped poly(oxyalkylene)-containing polyamide with a multifunctional compound having at least one ethylenically unsaturated group and a function group coreactive with the capping amine groups of the amine-capped poly(oxyalkylene)-containing polyamide. The amine-capped poly(oxyalkylene)-containing polyamide is a copolymerization production of a mixture comprising: (a) at least one poly(oxyalkylene)diamine, (b) optionally at least one organic di- or poly-amine, (c) at least one dicarboxyl derivative, (d) optionally at least one polycarboxyl derivative, and (e) a carbodiimide. The crosslinkable poly(oxyalkylene)-containing prepolymer of the invention can find use in economically producing contact lenses which have improved thermal stability. In addition, the present invention provides method for making a medical device, preferably an ophthalmic device, more preferably a contact lens.

    摘要： The present invention generally relates to a method for making made-to-order (MTO) or customized silicone hydrogel lenses which have printed images on and/or below lens surfaces. A preferred method of the invention comprises printing and curing an ink on the molding surface of a mold for molding a single-side molded lens blank, producing the single-sided molded lens blank having a molded surface corresponding to one of the anterior and posterior surfaces of the lens to be produced and having an image embedded in the lens body and below lens surface, and directly lathing the lens blank on the side opposite to the molded surface to form the other lens surface. Colored silicone hydrogel lenses produced according to the invention will be useful as daily wear lenses and extended wear lenses. The lenses will allow alteration or enhancement of a patient's eye color.
