  • Patent number: 4908997
    Abstract: A method and system for generating a lens by grinding a lens blank with a tool in a working position calls for a diamond tool to be disposed only angularly, the lens being moved in an X,Y relationship so that the relative cutting position is properly maintained. The angular disposition and X,Y relationship of the tool and the lens are pre-calculated by a computer, and the digital data thus obtained are converted to analog data for controlling a servo system. In accordance with the invention, when a certain range of curves is entered via a digital keyboard, a computation is made by computer to determine if an interference between the spindle holding the diamond tool and lens will exist, or if an interference between the lens and a chuck will exist. If an interference will exist, the chucked lens is caused to rotate around the optic axis by precisely 180.degree.

  • Patent number: 4392334
    Abstract: A method and apparatus for handling and dispersing a coolant and/or working fluid in ophthalmic lens processing equipment and the like. The apparatus includes a dispersing member (50) including a landing surface (52). An extension strip (62) projects away from the landing surface and includes a leading edge (64) having a compound arcuate contour. In operation a columnar flowing fluid (60) is directed onto the landing surface where it is spread into a sheet of flowing fluid (80). The sheet of fluid is guided away from the landing zone and onto working members operably intended to receive the fluid.

  • Patent number: 4373298
    Abstract: Disclosed is an automatic edge beveller for removing the sharp peripheral edges of ophthalmic lenses. It comprises (a) first apparatus for positioning an ophthalmic lens perpendicular to a first axis which extends through the lens, (b) second apparatus for rotating the lens about the first axis, (c) third apparatus for translating the ophthalmic lens parallel to the first axis, (d) a grinding wheel, and (e) fourth apparatus for rotating the grinding wheel about a second axis which intersects the first axis at an acute angle.

  • Patent number: 4328060
    Abstract: A method and apparatus for removing a block releasably adhered to the surface of an ophthalmic lens.The apparatus includes a base and a first and second stanchion extending upwardly from the base. First and second opposing gripping members are mounted at the distal ends of the first and second stanchions respectively wherein an operator may place lateral surfaces of a block adhered to the surface of an ophthalmic lens between the opposing gripping members and peel the lens away from the secured block using the first gripping means as a fulcrum.
