Abstract: A method of sorting articles having major and minor surfaces such that they normally assume a position presenting one major surface against a support surface and an opposed major surface spaced from said support surface wherein the articles are aligned on a support surface and advanced in a guided single file past a discriminating means which alters the path of advance of those articles having a first given orientation of its major surface relative to the guide means. The articles of the opposite major surface orientation relative to the guide means support surface are thus segregated. Both segregated groups of articles can be merged following their orientation to a like major surface relationship to a reference support surface.A turntable imposes centrifugal forces on the articles to be sorted to pass them to a tangential guide chute in single file.

Abstract: This invention relates to a method of moving a plurality of two-piece canning jar-type lids in series to a feed mechanism which will single-line the caps and maintain them in assembled position. The single-lining is arranged to approach the path of movement of a plurality of containers also moving in series on their side with their axes horizontal. The caps are brought, under gravity and at an angle, to the path of movement of the finish or neck of the jars such that the finish of the jars or containers individually engage and move the caps from the supply of caps. The caps are then retained on the finish of the jar and by reason of the movement with the jar, in a linear path, the caps are rotated and thereby threaded onto the finish of the containers.

Abstract: An inline magnetic mixer for flowing fluids. A magnetic particle is contained within a flow tube through which a fluid passes. A coil made of electrically conductive material is positioned in close proximity to the flow tube and outside the flow tube. A low voltage, oscillating electrical supply energizes the coil. This sets up an oscillating magnetic field within the flow tube which causes the magnetic particle to oscillate longitudinally within the flow tube, thereby mixing the fluid stream passing through the flow tube.

Abstract: A convenience closure having a removable central panel. A convenience closure is attached to a can end to seal the can. The closure includes a removable central panel; a panel fold with an endless severing line formed in its upper surface; a chuck wall fold which has a nose portion that extends radially inwardly farther than the severing line and overlies the severing line; and a pull tab, attached to the central panel, which has a nose portion that extends to the severing line. The panel fold includes a nose portion that extends to a position adjacent to and under the severing line. To remove the central panel, the pull tab nose is depressed to break the severing line. Then, the pull tab is moved upwardly to complete the breaking of the severing line and remove the central panel. Breaking the severing line forms two sharp raw edges; one lies under the nose of the chuck wall fold and is thus protected. The other raw edge is formed adjacent the nose of the panel wall fold.

Abstract: This invention relates to an apparatus for moving a plurality of two-piece canning jar-type lids in series to a feed mechanism in the form of a magazine which will single-line the caps and maintain them in assembled position. The single-lining mechanism is designed to feed lids into the path of movement of a plurality of containers, also moving in series on their sides with their axes horizontal. The caps or lids are carried at an angle to the path of movement of the finish of the jars such as that the finish of the jars or containers will each individually remove a cap from the supply of caps. The caps are then retained on the finish of the jar and are moved with the jar, in a linear path, with the caps being rotated by frictional engagement and thereby threaded onto the finish of the containers.
