Patent number: 7185515Abstract: An invert assembly for an individual section glassware forming machine includes an invert base that is oscillated about an axis between angularly spaced apart first and second positions, a double ended ball screw positioned co-axially with the axis and having spaced apart oppositely threaded portions, first and second nuts each threadably engaging one of the oppositely threaded portions of the ball screw so that the nuts reciprocate toward and away from each other in response to rotation of the ball screw, and first and second neck ring arms respectively engaging the first and second nuts so that the neck ring arms reciprocate toward and away from each other along the axis with the first and second nuts. Preferably, the invert base is oscillated about the axis by a first reversible electric motor, and the ball screw is driven for rotation in opposed directions by a second reversible electric motor to move the nuts and neck ring arms toward and away from each other along the axis.Type: GrantFiled: June 27, 2003Date of Patent: March 6, 2007Assignee: Owens-Brockway Glass Container Inc.Inventors: Larry N. Shue, Paul B. Mohr, David D. Soley, Ronald P. Warnecke, Thomas R. Kirkman, William F. Mazur, Jonathan R. Nadler, W. Patrick Holbrook, D. Wayne Leidy

Patent number: 7063498Abstract: A takeout arm assembly (10) for an I.S. glass container forming machine, the arm assembly having a housing (14) that is oscillatible about the central axis of a first shaft (12). The housing has a first gear (16) that is coaxial with the first shaft and oscillatible with the housing, and with respect to the first shaft, the housing further having a second gear (18) that is positioned within and is rotatable with respect to the housing. The second gear is spaced from the first gear with the axes of the first and second gears being parallel to one another. A rack (30) having teeth in engagement with teeth on the first gear and the second gear is caused to move rectilinearly by oscillating motion of a reversible a.c. servo motor (26) that serves to drive the first gear, to thereby transmit turning motion from the first gear to the second gear.Type: GrantFiled: December 3, 2003Date of Patent: June 20, 2006Assignee: Owens-Brockway Glass Container Inc.Inventors: Frank J. DiFrank, Larry N. Shue, Thomas R. Kirkman

Patent number: 6558349Abstract: A method and apparatus for retaining a catheter tip in a fixed position within a blood flow and preventing it from contacting a blood vessel wall. The apparatus includes a tip retainer at the distal end of the catheter that anchors the tip of the catheter within the blood vessel. The catheter tip is retained within the blood vessel spaced from the wall to ensure that it does not contact the wall of the blood vessel. This reduces damage to the blood vessel caused by chronic movement and contact between the catheter tip and the wall of the blood vessel. In one embodiment, the tip retainer includes a prong that penetrates the wall of the blood vessel, thus preventing the catheter tip from moving longitudinally within the blood vessel. In alternative embodiments, the tip retainer contacts the wall but does not penetrate the wall.Type: GrantFiled: April 25, 2000Date of Patent: May 6, 2003Inventor: Thomas R. Kirkman

Patent number: 6446788Abstract: A glass machine system in accordance with presently preferred embodiments of the invention includes a glassware manufacturing machine for manufacturing articles of glassware and transferring the articles to a linear conveyor, at least one linear chain conveyor for receiving and transporting such articles from the machine, and a speed sensor for monitoring linear speed of the conveyor. The speed sensor includes a magnetic energy source, a magnetic energy sensor and bracketry mounting the source and sensor adjacent to the conveyor. The chain conveyor teeth affect magnetic energy coupling between the source and sensor as the conveyor passes adjacent to the sensor. Electronic circuitry is responsive to signals from the sensor for determining linear speed of the conveyor and maintaining a constant linear speed at the conveyor.Type: GrantFiled: March 12, 2001Date of Patent: September 10, 2002Assignee: Owens-Brockway Glass Container Inc.Inventors: D.

Patent number: 6314762Abstract: A neck ring arm assembly for a glass container forming machine of the individual section type comprising a horizontally extending invert shaft and a vertically extending cylinder with a rack that engages a spur gear attached to the invert shaft to oscillate the invert shaft. In a first embodiment, the invert shaft has an inner annular sleeve keyed to it, and the inner annular sleeve has a polygonal exterior, preferably a hexagonal exterior. First and second outer annular sleeves surround the inner annular sleeve to be oscillatable therewith, but reciprocable with respect thereto.Type: GrantFiled: November 19, 1999Date of Patent: November 13, 2001Assignee: Owens-Brockway Glass Container Inc.Inventor: Thomas R.
