Patent number: 8024893Abstract: A vehicular, powered slider drive interface and drive assembly are provided. The interface has a driver bracket, which includes contact surfaces, mounted on a regulator, a driver receiver, which includes contact surfaces, mounted on a slider panel, and separate bumpers disposed on each driver surface. When the regulator is caused to move in an open direction, a first driver contact surface is brought into selectively non-attached pushing or pulling mechanical contact with a first driver bumper to smoothly open the slider-panel. When the regulator is caused to move in a closed direction, a second driver contact surface is brought into selectively non-attached pushing or pulling mechanical contact with a second receiver bumper to smoothly close the slider panel. Since the driver bracket and the driver receiver are not rigidly/directly mechanically attached, the slider panel slides freely without binding and requiring precise alignment of the drive interface.Type: GrantFiled: February 18, 2004Date of Patent: September 27, 2011Assignee: Pilkington North America, Inc.Inventor: John H.

Patent number: 7975509Abstract: A glass bending line for quickly shaping a complex bent glass sheet is provided that includes moving a ring-type female mold, which has a heated glass sheet placed on it, and a full face heated male mold, toward one another. Upon making shaping contact between the glass sheet and the male mold, a vacuum is applied through holes extending through the male mold, for a time sufficient to form the glass sheet to a desired shape. When the glass sheet has been shaped, the vacuum is terminated and pressurized air is connected to the holes to release the bent glass sheet from the male mold. The bent glass sheet is then quickly transported to a quenching station or an annealing station on a continuous conveying device. Hence, the complex bent glass sheet is achieved without the use of a shuttle ring.Type: GrantFiled: June 27, 2007Date of Patent: July 12, 2011Assignee: Pilkington North America, Inc.Inventors: Robert J. Boisselle, Thomas G. Kleman, Daniel P. Lubelski

Patent number: 7866187Abstract: A press bending station includes an annular mold (5) and a full-face mold (6). Holes (10), selectively connected to a negative pressure source, are placed in portions of the full-face mold (6) that are determined by the configuration of the annular mold when the annular mold comes into contact with a heated glass sheet (2) during the press bending process. The sheet (2) is drawn by negative pressure through the holes (10) towards the full-face mold (6) and thus acquires its shape. Positive pressure may be selectively applied to the holes (10) to release the sheet (2). According to the invention, at least some of the holes (10) are arranged in at least one groove (11) formed in the mold face of the full-face mold. The grooves (11) according to the invention accelerate considerably the removal by negative pressure of the air between the molding face of the full-face mold (6) and the glass sheet (2) to be bent and thus improve the press bending process.Type: GrantFiled: September 24, 2003Date of Patent: January 11, 2011Assignees: Pilkington North America, Inc., Pilkington Automotive Deutschland GmbHInventors: Robert J.
