Patent number: 8893762Abstract: A horizontally expandable, portable wall partition is incrementally expandable between a closed position and an open position. The portable wall partition consists of a number of upright panel members that are sidewardly adjacent and vertically parallel to one another. These panel members are interconnected by connectors that allow the panels to slide past one another from the closed position to the expanded position. The partition may also have non-sliding end members that provide stability to the partition. The partition may also have nested panels.Type: GrantFiled: October 31, 2012Date of Patent: November 25, 2014Assignee: Versare Solutions, Inc.Inventors: Jeffrey W. Ryan, Robert J. Jantschek

Patent number: 6574837Abstract: A three point pivoting 360° articulable pinchless hinge connects two members which may pivot 360° with respect to each other. The hinge has two opposing couplers, each having a toothed semicircular portion meshed with the opposing coupler toothed semicircular portion. Each coupler is adapted to be connected to one of the members to be pivoted with respect to each other. A pin is in each coupler extending along an axis of the semicircular portion thereof. A link connects each pin to maintain the meshed engagement of the couplers through 360° of coupler pivotal rotation with respect to each other. The link has a sufficient width substantially that of the width of the coupler body as to block and prevent the meshed semicircular portions from pinching an individual's finger or object. The hinge may also have a locking mechanism or detent which locks the two members at 180° from each other.Type: GrantFiled: April 3, 2001Date of Patent: June 10, 2003Assignee: Versare Solutions, Inc.Inventor: Robert J. Jantschek

Patent number: 6009930Abstract: A portable wall partition having a three point pivoting 360.degree. articulate pinch less hinge connecting two panels which may pivot 360.degree. with respect to each other. The hinge has two opposing couplers, each having a toothed semicircular portion meshed with the opposing coupler toothed semicircular portion. Each coupler is adapted to be connected to one of the panels to be pivoted with respect to each other. A pin is in each coupler extending along an axis of the semicircular portion thereof. A link connects each pin to maintain the meshed engagement of the couplers through 360.degree. of coupler pivotal rotation with respect to each other. The link has a sufficient width substantially that of the width of the coupler body as to block and prevent the meshed semicircular portions from pinching an individual's finger or object. The portable wall partition has two full panel end members which provide support, rigidity, privacy, and noise reduction.Type: GrantFiled: April 12, 1999Date of Patent: January 4, 2000Assignee: Versare Solutions, Inc.Inventor: Robert J.

Patent number: 5618225Abstract: The present invention relates to a method and apparatus for abrading a workpiece. The apparatus includes an abrasive tape having a microstructured surface on the back face thereof, and a support shoe having a microstructured surface on an exposed pressure face. The two microstructured surfaces intermesh and resist displacement of the abrasive tape with respect to the pressure face as the workpiece is rotatively abraded.Type: GrantFiled: June 6, 1995Date of Patent: April 8, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert J. Jantschek, Forrest J. Rouser, Mark L. Sterner, Theodore J. Testen
