Abstract: A parts immersion system and method includes a trough through which a conveyor belt carries the parts. A chemical solution is introduced into the trough through an opening in the bottom of the trough, from above the trough, and/or from the sides of the trough. The parts on the conveyor belt in the trough have a tendency to retard liquid movement out of the open ends of the trough thereby allowing the chemical solution to accumulate in the trough resulting in a greater immersion of the parts in the chemical solution. A gate may be provided near one or both ends of the trough to further enhance the accumulation of the chemical solution in the trough. Flights may extend upwardly from the conveyor belt to further enhance liquid retention in the trough between the flights. Flexible seals at the ends of the flights may contact sidewalls of the trough. One or more vibrators may be provided to enhance drainage of the chemical solution from the parts as the parts exit the trough.

Abstract: An oven apparatus has an oven enclosure with a heating zone and has two fans that remove air from the heating zone during purging and during normal operations. One of the two fans, called the exhaust fan, is a fixed speed fan in some embodiments. The second fan is a variable speed fan in some embodiments. The oven apparatus may have a vestibule at a conveyor opening with a fan dedicated to exhausting the vestibule. The oven apparatus may have an air seal between the vestibule and a heating zone of an oven chamber.

Abstract: Processes are disclosed for the coating of objects with a coating composition. The processes include positioning the objects on a continuous belt comprising a supporting member positioned to retain the object thereon, conveying the continuous belt with a drive member such that the continuous belt passes through both a coating unit and a drying unit, coating the objects on the continuous belt with the coating composition, and drying the objects on the continuous belt.

Abstract: Apparatus and systems for the application of a coating to an object. The systems comprise a continuous belt comprising at least one supporting member positioned to retain the object thereon, a drive member in operative engagement with the continuous belt, a coating unit in communication with the continuous belt, and a drying unit in communication with the continuous belt and the coating unit and arranged such that the object is coated and dried on the continuous belt. The supporting member of the belt may include at least one blade member comprising a plurality of projections, at least one of which is positioned to contact the object.

Abstract: This invention relates to a floating roof support for a liquid storage tank that reduces the loss of vapor from the tank and that supports the roof in a low and a high position.

Abstract: A folding pour spout, particularly, for detergent cartons. The spout is formed from a spout blank preferably comprising a single thin sheet of plastic. The spout blank includes a first spout-forming panel having a pull tab, a second spout-forming panel including notches and a panel for attachment to a carton. The reduced thickness of the spout blank facilitates manufacturing of the carton.

Abstract: A plastic closure for cartons which permits controlled dispensing of product. The closure is a fitment comprised of a thin material which is of such a minimal thickness that it does not tend to cause uneven stacking of the cartons when they are in flattened form, prior to their erection. The closure is generally thin enough to be accommodated within a carbon having either a 3- or 4- point rule score and normal score caliper balancing. The closure comprises a base member having an aperture, and a cover member which has a depending plug which fits within the aperture of the base when the cover member is in the closed position.
