Abstract: In dressing a grinding wheel having a non-cylindrical contour, the wheel is moved in a path corresponding substantially to the desired wheel contour by first and second CNC controlled slides while a single point diamond or diamond roll dresser is rotated by a CNC controlled rotary mechanism through selected angles during traversal of the wheel therepast to maintain a vertical reference plane containing the centerline or mid-plane of the diamond dresser point or radius substantially orthogonal to a vertical reference plane containing a tangent to the wheel contour path. Maintenance of the orthogonal relationship between the single point diamond dresser point or radius and wheel contour path during traversal results in the desired wheel contour being accurately dressed.

Abstract: A tool and machine are provided for pressure forming teeth in the periphery of a cylindrical, tubular workpiece such as a power transmission member by rolling. The tool has a working surface which improves the flow characteristics of the metal work piece during the tooth forming operation. Flow characteristics are particularly improved during initial contact of the tool with the workpiece by providing an initial toothless clamping section on the tool preceding the first toothed working section. The clamping section minimizes or eliminates radial workpiece separation from the mandrel ahead of the toothed section during the initial stage of the tooth-forming operation, which separation is manifested as a wave or buckling effect in the workpiece during initial forming and as an out-of-round condition in the final product.

Abstract: Apparatus for manufacturing pin-stripe or common color thin-walled hollow shells for parts such as automobile door panels, controls and instrument panels from dry thermo-plastic powders include a powder box divider to form two or more compartments in a powder charge box and means for joining the charge box divider end-to-end with a mold separation edge on an open-ended heated mold for separating the mold into two or more sections; each compartment of the charge box has a different color powder. The charge box and mold are joined and then are rotated so that the powder is distributed into each mold section by gravity flow. Thereafter a third powder is distributed against an exposed division surface on the mold separation edge so as to form a pin stripe or common color for bonding prior cast multi-colored sections of a resultant shell of cured material.

Abstract: In pressure forming splines or teeth in the axially-extending sleeve of a clutch hub having a cylindrical oil seal surface adjacent the sleeve, a pair of special tooth-forming racks adapted to intermesh with a toothed mandrel with the sleeve therebetween and a pair of special support racks adapted to contact the oil seal surface are used. Each tooth-forming rack includes a first working surface with a plurality of toothed sections interrupted and spaced apart by toothless sections in an alternating sequence and each further includes a second working surface with uninterrupted toothed sections. Each support rack includes a first working surface with raised support sections interrupted and spaced apart by lower non-supporting sections in a proper alternating sequence and configuration to insure that the raised sections support the oil seal surface when the interrupted toothed rack sections of the tooth-forming racks deform the sleeve.

Abstract: The adapter member includes a threaded male portion adapted for threadable engagement in a threaded bore of the punch and a threaded female portion of smaller diameter adapted for threadable engagement with a small diameter threaded end of the draw stud which can pass through an initial small diameter pilot hole in the workpiece. The adapter member allows the punch to accommodate a draw stud of sufficiently small diameter to fit through the pilot hole and allows punching of a larger diameter hole in light gage or non-ferrous materials without enlarging the pilot hole. This arrangement eliminated the need in the past for the additional step of enlarging the pilot hole to accept a draw stud of larger diameter that was threaded directly into the thread bore of the punch for punching larger diameter holes in both heavy and light gage material.

Abstract: The invention provides a device for supporting a mold insert in space inside a mold cavity. A pilot and keeper assembly rests on the top of a mold part and extends into a mold cavity and through a small hole in the mold insert. Movement of a handle, which is part of the pilot and keeper assembly of the mold part, is transmitted through a shaft to a retaining means, which engages the opposite extremity of the hole to retain the insert in position during molding operations. After plastic is inserted into the base of the mold cavity and a sufficient curing time has transpired, the handle is rotated back to its initial position, thereby returning the retaining means to a nonretention position, and the pilot and keeper assembly is withdrawn from the mold.

Abstract: A sterilization apparatus and method for sterilizing the interiors of paperboard containers, wherein such apparatus and method are operative prior to the container being mounted on a mandrel assembly on which the container bottom closures are formed, closed and sealed. This is accomplished by providing nebulizing means for communicating a suitable sterilant fog through and onto the inside surfaces of the carton blank immediately after it has been removed from a magazine and opened into a four-sided tubular shape, thereby greatly increasing the total interior sterilizing time available prior to the container being filled, as compared to conventional sterilization processes which are operative after the bottom panels of the carton have been closed and sealed.

Abstract: A folding and tucking apparatus for a container end closure forming and sealing machine where a pair of oppositely rotating arms, each having a freely rotatable roller mounted on its distal end, are adapted to engage and move a heat-activated, plastic coated carton end closure panel around a score line from a vertical to a horizontal attitude. The result is that, while the rollers thus move the panel, the relative movement between the rollers and the panel is minimal, thereby preserving clean, unmarred surfaces on end panels of cartons which will be characteristically observed by consumers in the marketplace.

Abstract: There is disclosed a flat end closure arrangement for a thermoplastic coated paperboard container, and the blank therefor, wherein a suitable adhesive or anti-sealant is applied to four sets of four quadrant areas around intersections of score lines about which adjacent panels are folded both laterally and longitudinally in substantially 180.degree. bends, to provide areas of slippage between selected adjacent panels, thereby diminishing the chances of cracking of the thermoplastic coating at the bend locations.
