Patent number: 8447763Abstract: A numbering system for antecedents and outcomes providing a method for numbering antecedents and outcomes that reveals underlying information of relationships. The numbering system for antecedents and outcomes utilizes a mathematical relationship and an antecedent's or outcome's existing characterizing information to assign a unique indexing number identifying each antecedent and outcome. In an antecedent numbering system, the unique indexing number is able to provide information about the contributor line number, the cohort, the combination of the preceding multiple antecedents, and the sequence number of the outcome. In an outcomes numbering system, the unique indexing number provides information about the sequence line number, the cohort, the combination of the antecedents, and the order numberof the outcomes.Type: GrantFiled: June 7, 2011Date of Patent: May 21, 2013Inventor: Capers Walter McDonald

Patent number: 8226397Abstract: Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish portion, is positioned to enable insertion of a mandrel into an open top aperture of the finish portion to widen the finish.Type: GrantFiled: September 2, 2011Date of Patent: July 24, 2012Assignee: Graham Packaging Company, LPInventors: Keith Barker, Brian Lynch, Walter McDonald, Norbert Seitel

Patent number: 8151970Abstract: The present improvement is useful for orienting and feeding blow molded preforms. Cylindrical preforms have larger threaded necks with larger encircling discs below the necks. A pair of belts is provided for conveying objects downstream. The gap between these belts is less than the disc diameter of the preforms. An output means is provided for receiving the oriented objects and directing them downstream. A means is provided at the output of the belts for deflecting any improperly oriented preforms back for recirculation. An increase in the feed rate of the preforms is achieved by an agitation means such as a blower positioned to disperse the interlocked assemblages and help move the preforms down into the belts.Type: GrantFiled: January 27, 2009Date of Patent: April 10, 2012Assignee: Norwalt Design Inc.Inventors: Walter McDonald, Norbert J.

Publication number: 20040144618Abstract: Apparatus and methods for rapidly orienting and feeding generally cylindrical, elongated objects having a maximum transverse diameter Y. First and second conveying belts are provided having input and output ends for cooperatively conveying such objects toward a downstream processing line. The belts are mounted so that their respective conveying surfaces are movable in a common parallel direction. The facing edges of the conveying surfaces of these belts are spaced from one another to define a uniform gap between them of a dimension less than Y. The conveying surfaces are upwardly sloped away from the gap, to define a zone converging downwardly in the direction of the gap. Object input means deposit the initially unoriented elongated objects at the input ends of the conveying belts. The belts are moved in a common direction, but at different speeds.Type: ApplicationFiled: January 29, 2003Publication date: July 29, 2004Inventors: Walter McDonald, Norbert J. Seitel

Patent number: 4878575Abstract: Apparatus is provided for accepting an initially presented population of randomly oriented articles formed from a soft elastomeric material, and providing a high-speed output stream, wherein all said articles are commonly oriented for further mechanical manipulation. The apparatus includes an input bowl for accepting the articles, which bowl includes a rotatable central disk for feeding objects incident thereupon to the periphery of the disk. A continuous wall member extends upwardly from the disk periphery about a major arced zone. An output section defined adjacent the periphery of the disk at the portion opposed to the arced zone receives and delivers the articles from the disk, and an arrangement is provided for causing the disk to undergo vibratory motions while it is rotated.Type: GrantFiled: December 30, 1988Date of Patent: November 7, 1989Assignee: Norwalt Design, Inc.Inventors: Walter McDonald, Norbert J.

Patent number: 4615428Abstract: Apparatus is provided for accepting a population of articles of the type having one axis generally longer than the other and one end different from the other with random orientation of the ends and providing a high-speed output stream of articles with all the ends thereof commonly oriented. The apparatus comprise a rotatable wheel adapted to accept the articles with randomly oriented ends in the periphery thereof and advance said articles to an output station having means for constraining the articles during advance thereof in the wheel and means for biasing said articles to turn end for end within the wheel only as the result of an article being in an undesired endwise orientation.Type: GrantFiled: August 16, 1984Date of Patent: October 7, 1986Assignee: Norwalt Design, Inc.Inventors: Walter McDonald, Norbert F. Seitel

Patent number: 4401203Abstract: Apparatus is disclosed for accepting an initially presented population of randomly oriented elongated slender articles which terminate in an enlarged head portion, and providing a high-speed output stream, wherein all said articles are commonly oriented for further mechanical manipulation. The apparatus comprises an input bowl for accepting the articles, which bowl includes a rotatable central disk for feeding objects incident thereupon to the periphery of the disk. A continuous wall member extends upwardly from the disk periphery about a major arced zone, the bottom of the wall member being spaced from the disk to define a gap through which the elongated portion of the articles may protrude while the heads of same continue to ride upon the disk periphery in sliding contact with the side wall. An output section defined adjacent the periphery of the disk at the portion opposed to the arced zone receives and delivers the articles from the disk.Type: GrantFiled: October 21, 1981Date of Patent: August 30, 1983Inventors: Walter McDonald, Norbert F. Seitel

Patent number: 4214656Abstract: Apparatus for accepting an initially presented population of randomly oriented container caps and providing an output in-line stream of said caps wherein the open ends of the caps face in an upward direction to facilitate further processing of the caps. The apparatus comprises a feeder bowl for accepting the randomly oriented caps, and feeding from an output port thereof, an in-line stream of caps oriented in a substantially horizontal plane. An inclined twisting chute extends from the output of the feeder bowl. This chute receives the in-line stream of caps and twists the plane of advance of same through 90.degree., whereby the caps are reoriented to a stream wherein their diameters are substantially in a vertical plane.Type: GrantFiled: June 26, 1978Date of Patent: July 29, 1980Assignee: Norwalt Design, Inc.Inventors: Walter McDonald, Norbert F.
