Abstract: An eyewinder system 10 has stations 100-108 for straightening, bending, measuring and transporting a wire 11 to form an eyewire 109. A controller 120 controls each station. Using information from tension and length measuring stations 104, 105, the controller 120 can accurately operate the second bending station 107. The eyewire 109 is inspected for accurate bends by an inspection system 140 that compares the bends in the eyewire 109 to predetermined radii of curvature.

Abstract: A lens inspection system 10 has two cameras 50, 51 for capturing plan and edge images views of a lens 20 and providing pixel data signals representative of the images. The pixel data signals corresponding to the plan and edge images are analyzed by a computer 70. The computer uses the pixel data signals to calculate the circumference of the image, the lengths of radii to circumferential pixels, and the bevel angle of the lens 20. Such data are compared to data stored in memory 710 and a visual display 74 indicates the difference between the image and the stored data.

Abstract: A computer numerical control machine system for edging lenses controls the rotation and displacement of a lens workpiece with respect to a edging tool in accordance with a lens shape stored in memory. The system continuously translates the lens workpiece axially across the surface of the wheel to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool. The system compares the lens size with predetermined dimensions and compenates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size. The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece.

Abstract: Combined candle holder and mold apparatus includes a free-standing container having an open upper end and within which candle supporting structure is provided on which a burning candle is adapted to be supported so as to extend upwardly through and beyond the open container end. A wick has one of its ends connected to the candle supporting structure and its other end connected to a removable bottom closure member of the container so that the wick extends in the direction of the axis of the container through the substantial height thereof. In use, a burning candle is mounted on the supporting structure so that the apparatus functions as a candle holder. As the candle continues to burn the molten wax dripping therefrom falls into the container where it accumulates and solidifies around the wick so that the container thereby acts as a mold for the newly-forming candle.
