20150308943 | GLASS SHEET ACQUISITION AND POSITIONING MECHANISM FOR AN INLINE SYSTEM FOR MEASURING THE OPTICAL CHARACTERISTICS OF A GLASS SHEET - A glass sheet acquisition and positioning mechanism and associated method are utilized in an in-line glass sheet optical inspection system. The mechanism includes an exterior support frame mounted in proximity to one of the glass sheet processing system conveyors, and an interior support frame operably connected to the exterior support frame such that the interior support frame may be selectively positioned from its first orientation to a second orientation whereby the retained glass sheet is positioned between the camera and the screen at a preselected position. The interior support frame is also operably connected to the exterior support frame to provide for positioning of the interior support frame to a third orientation in which the glass sheet is released from the interior support frame for continued movement on the conveyor. An in-line glass sheet optical inspection system incorporating the glass sheet acquisition and positioning mechanism is also disclosed. | 10-29-2015 |

20150218029 | THREE STAGE FORMING STATION AND METHOD FOR FORMING A HOT GLASS SHEET WITH TRANSVERSE CURVATURE - A glass sheet forming station and method utilize first and second upper molds and a lower mold to provide three stage forming. The glass is curved on the upper mold in the first stage but retains straight line elements transverse to the curvature. Transfer of the initially formed glass sheet from the first upper mold to the lower mold then provides the second stage of gravity forming and the glass sheet is then press formed between the second upper mold and the lower mold in the third stage which reduces optical distortion in the central viewing area of the formed glass sheet. In one embodiment the glass sheet is moved horizontally on the lower mold, and in another embodiment the glass sheet is moved horizontally on the first upper mold. | 08-06-2015 |

20140270391 | SYSTEM AND METHOD FOR EVALUATING THE PERFORMANCE OF A VEHICLE WINDSHIELD/WIPER COMBINATION - A system and method for evaluating the performance of a vehicle windshield wiper system includes a digital camera positioned to allow the camera to capture an image of the surface of the windshield, and a computer including logic for capturing a digital image of the surface of the soiled windshield, capturing a digital image of the surface of the wiped windshield, and comparing the data from both captured images to develop selected indicia related to the extent to which the soil has been removed from the windshield. | 09-18-2014 |
20140260431 | GLASS SHEET SUPPORT STRUCTURE - A support structure for supporting a heated glass sheet in connection with a bending operation includes a frame, a support ring adjustably supported on the frame for supporting a peripheral portion of the glass sheet, and multiple rib assemblies associated with the frame. Each rib assembly includes a laterally extending rib supported on the frame and multiple spaced apart support members connected to the rib and configured such that at least a portion of each support member is adjustable with respect to the rib. Furthermore, each support member is configured to contact a respective inner portion of the glass sheet to support the respective inner portion of the glass sheet until the glass sheet has been sufficiently cooled. | 09-18-2014 |

20120297835 | GLASS SHEET BENDING STATION - A glass sheet bending station includes a framework, lower and upper deformable molds for receiving therebetween a glass sheet to be bent, and lower and upper linkages that respectively support the lower and upper molds on the framework. Each linkage includes connector links that are fixedly connected to the associated mold and that have pivotal connections to each other, wherein the pivotal connections define pivot axes that are parallel to a shape defined by the connector links between the lower and upper linkages throughout the bending. Each linkage also has control links connected to the connector links thereof such that the control links are pivotable about axes that extend perpendicular to the shape defined between the lower and upper. Furthermore, at least one of the control links of each linkage is configured to permit glass sheet bending by linkage movement on one side thereof independently of the other side thereof. | 11-29-2012 |
20120098959 | METHOD AND APPARATUS FOR MEASURING TRANSMITTED OPTICAL DISTORTION IN GLASS SHEETS - An apparatus and associated method for measuring both transmitted optical distortion and other minimal visible defects in the surface of a glass sheet. The disclosed apparatus includes a glass stand which receives a glass sheet for mounting between a background screen which includes a pre-defined contrasting pattern, and a digital camera which captures an image of the pattern transmitted through the glass sheet. The digital image is downloaded to a computer that is suitably programmed to analyze the image data to determine (1) optical distortion indicia, including the magnification and lens power, in the observed image of the pattern transmitted through the glass sheet, and (2) small visible optical or obstructive defects on the glass sheet. | 04-26-2012 |
