摘要:
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.

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. The mandrel may include a lower heated tapered portion for expanding the finish, and an upper cooled body portion on which the expanded finish may be cooled. The article may then be sent to a finish crystallizing station having a heating device that heats the widened finish portion for a time and temperature selected to crystallize at least a portion of the widened finish. A sizing mechanism positionable in the widened finish supports the finish during crystallization.

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.

Apparatus for orienting and feeding blow molded preforms which are elongated generally cylindrical plastic objects, one end of which is a threaded neck portion for the ultimate blow molded container, and the other end of which extends from the opposed end of the cylindrical object as a narrower and heavier tubular portion which during the blow molding operation will be softened and enlarged into the ultimate container, the preform further including an encircling handling disc between the said threaded neck portion and tubular portion which has a larger diameter than the remaining portions of the preform, the disc serving to facilitate handling of the preforms. 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 that of the disc. 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 preforms at the input ends of the conveying belts. The belts are moved in a common direction, but at different speeds. The preforms are rotated by contact with the differentially speeding belts as they descend into the converging zone and become supported at the gap and conveyed by riding on the edges of the moving belts which border the gap. Object output means at the ends of the belts receive the oriented objects and direct them toward the downstream processing line. Means at the output ends of the belts deflect any preforms which are not properly oriented and seated in the gap; and preform output means at the output end of the belts receive the oriented preforms and direct them toward the processing line. In order to preclude or minimize the preforms resisting deflection due to frictional lock between the disc portion of the preform and an adjacent lateral edge of an opposed belt, one or both of the lateral edges of the belts abounding the gap are formed to diverge upwardly away from the belt gap.

An elevatable operator-actuated lifting device, including a lower support frame and a platform section telescopically interfitted with the support frame as to be elevatable with respect thereto. Hydraulically actuated piston and cylinder means are provided for telescoping and de-telescoping the platform section with respect to the support frame, to enable elevation and lowering of the platform section. Means moveable with the platform section, including a manually actuated hydraulic pump, enable pressurization and de-pressurization of the piston and cylinder means, to thereby enable raising and lowering of the platform section by an operator standing thereupon.
