Abstract: A lid handling system employs a lid alignment assembly for aligning lids randomly placed on a rotating input disc, a lid separation assembly for separating lids spinning on a pair of horizontal spin bars into a counted stack, a vacuum pickup assembly for picking up a counted stack of lids, a pick and place assembly for transporting and placing stacks of lids into trays having upwardly bent side members, and a conveyor for conveying filled trays toward a carton.

Abstract: An apparatus for handling a plurality of lids or other predominately flat articles having two discrete sides, such as a top and bottom, delivering them in a common orientation, which includes a conveyor system for carrying the articles along the apparatus from an inlet end to a final discharge end and an air jet nozzle which directs compressed air to engage at least some of the articles to change their orientation. The conveyor system may include a number of orienting surfaces with at least a single disjoined area to provide conditions for article orientation, or re-orientation in specialized cases. The appropriate arrangement of any two of these surfaces provides varying degrees of automated flipping. Various forces, such as, but not limited to, air, vacuum and gravity, either separately or in combination, may assist in the flipping process. Such forces are selectively enabled by the detection of an improperly oriented article.

Abstract: A test apparatus for determining the corrosion protection performance of fluids includes a housing, an axial shaft mountable therein, a heating element, and a drive motor. The housing which contains the test fluid is preferably sealable to maintain a predetermined environment therein. The housing also includes a port or ports for introduction of corrosion initiating substances. The heating element is adjacent to a lower portion of the housing to provide increased temperatures within the housing when desired. Test specimens are mounted on the shaft and may be rotated in partially immersed emplacement within the bath.The process for determining the corrosion protection performance of a fluid comprises forming a bath of the test fluid and rotating a partially immersed, substantially corrosion free test specimen therein in the presence of a corrosive environment. Thereafter the specimen may be maintained in static and partially immersed emplacement within the bath.
