Patent number: 8695894Abstract: A system for dispensing liquid material with different configurations of air assisted fiberization or filament movement (e.g., meltblowing, controlled fiberization). In particular, front access for mounting a selected nozzle only requires adjustment of one lever and one fastener. Features of the lever and nozzle allow assisted ejection of the nozzle, even when the nozzle has become adhered to a die body through use. In addition, a nozzle mounting surface of the die body provides a universal interface to the various types of nozzles. An air cavity in the die body and air troughs in selected types of nozzles balance and adjust air flow.Type: GrantFiled: June 12, 2012Date of Patent: April 15, 2014Assignee: Nordson CorporationInventors: Charles A. Gressett, Jr., David E. Hardy, John M. Riney, Laurence B. Saidman, Paul Schmidt

Patent number: 6508617Abstract: Manipulators for safe, 360 degree rotation along at least two axes and horizontal and vertical translation of large, heavy objects are disclosed. Manipulators of the present invention include a support structure or open framework, a carriage, and an inner framework assembly. In some embodiments of the present invention, the inner framework assembly can be oriented substantially horizontally or substantially vertically. The inner framework assembly engages the work piece through the use of a support member that has one or more extension arms attached to its bottom surface which have one of more part grips at its ends. The extension arms further include a pair of rotating shafts that allow the work piece to rotate 360 degrees preferably along the central axis of the part grips. The inner framework assembly is capable of rotating 360 degrees about the axis of the central shaft.Type: GrantFiled: November 9, 2000Date of Patent: January 21, 2003Assignee: ABB Technology AGInventor: Charles Gressett
